Chapter 1. Introduction
The shadow banking system played a critical function in the 2007-2009 fiscal crisis. The FSB ( 2011b ) study has defined shadow banking as “ recognition intermediation which occurs outside or partly outside the banking system, but which involves purchase and adulthood transmutation ” , and the shadow banking system as “ the system of recognition intermediation that involves entities and activities outside the regular banking system ” . It provides a cheaper and more efficient manner for corporations to run into their demands on support, and was emerge as a complement to regular banking. However, the fiscal crisis shown that the shadow banking system can besides make a figure of hazards, in which the most of import one is systemic hazard.
A repurchase understanding is a fiscal contract that market participants used it as a funding method to run into short and long term liquidness demands, in which one participant borrows hard currency from the other by plighting a fiscal security as collateral. In U.S. repo market, a series of regulative alterations in the 1980s made the repo market an attractive beginning of short-run funding for primary traders to finance their places in the debt of the U.S. authorities, federal bureaus, corporations, and federal bureau mortgage-backed securities. Furthermore, another important alteration in 2005 makes repo minutess eligible for bankruptcy safe seaport protection based on any stock, bond, or security. In add-on, the rapid growing of money keeping by institutional investors, pension financess, common financess, provinces and municipalities, and non-financial houses is another chief driver for increasing usage of repos. Unfortunately, there is no official informations of the overall size of the repo market in U.S..
Since repos are the major constituent of the shadow banking system, and shadow banking is seen to trust on sweeping support such every bit repo as the sedimentations issued by traditional Bankss, and even seen as more dependent on these beginnings of support than traditional Bankss are on sedimentations, it is necessary to concentrate on the function of repo in the shadow banking system every bit good as in the 2007-2009 fiscal crisis, and discourse the effectual ordinance on repo market.

Chapter 2. Background of Dissertation
2.1 Shadow Banking System
FSB ( 2011a ) references that the outgrowth of the term “ shadow banking system ” reflected a acknowledgment of the increased importance of entities and activities structured outside the regular banking system that perform bank-like maps. The recent fiscal crisis demonstrated that shadow banking is extremely interrelated with the regular banking system and can hold an important impact on fiscal stableness. In the ulterior study, FSB ( 2011b ) defined shadow banking as “ recognition intermediation which occurs outside or partly outside the banking system, but which involves purchase and adulthood transmutation ” , and the shadow banking system as “ the system of recognition intermediation that involves entities and activities outside the regular banking system ” .
The traditional banking system based on doing and keeping loans with insured nest eggs as the chief beginning of financess, it borrowing short-run from other Bankss and imparting long-run to the retail consumer.
The shadow banking system based on the concern of packaging and reselling loans, it provides a cheaper and more efficient manner for corporations to run into their demands on short-run support, in which repos and asset-backed commercial paper ( ABCP ) are the chief beginning of financess. These Bankss provide recognition both straight and indirectly through three different procedures of fiscal transmutation:
Credit transmutation, which means they enhance the recognition quality to offer a scope of senior status and continuance, and a corresponding scope of hazard and return, from short-run AAA down to equity ;
Maturity transmutation, by which they finance long-run assets with short-run liabilities, it makes the term of their liabilities much shorter than their assets, and exposes short-run investors to market liquidness and continuance hazards ;
Liquidity transmutation, by which they fund illiquid assets with liquid liabilities, it causes the same consequence as adulthood transmutation through different techniques.
Harmonizing to one step of the size of the shadow banking system from FSB ( 2011 ) , it grew quickly before the fiscal crisis, from an estimated $ 27 trillion in 2002 to $ 60 trillion in 2007, and remained at around the same degree in 2010. Gorton and Metrick ( 2010a ) argue that the force from both supply and demand side cause the rapid development of shadow banking system before the current crisis: a series of alterations in inventions and ordinances eroded the Bankss ‘ competitory advantage ; and demand for collateral for fiscal minutess of bank promote the development of securitization and increase the usage of repos as a money-like instrument.
On the one manus, it should be recognised that interceding recognition through shadow banking can offer advantages to the fiscal system. First, shadow banking system provide an alternate beginning of funding for market participants to bank sedimentations. Second, since some non-bank entities increased specialisation, it provide more expeditiously recognition resource to run into the specific demands in the economic system and cut down the cost the investors. Third, it constitute an alternate beginning to diversify hazard other than traditional banking system.
On the other manus, nevertheless, as the fiscal crisis has shown, the shadow banking system can besides make a figure of hazards, in which the most of import one is systemic hazard. First, shadow banking concern exposed to the similar hazards as traditional Bankss, it financed by short-run deposit-like support of non-bank entities, which my lead to “ runs ” in the market if assurance is lost. Second, the operation of non-deposit beginnings of collateral support in shadow banking can be extremely leveraged without being limited by regulator, particularly when plus monetary values are rise and haircuts on secured funding are low. Highly leveraged minutess can increase the breakability of the fiscal system and go a beginning of systemic hazard. Third, the hazards in the shadow banking system can easy transmitted to the regular banking system since shadow banking concerns are frequently closely linked to the traditional banking sector. Which means that any failures in shadow banking can take to of import contagious disease due to the fact that Bankss frequently take portion in the shadow banking recognition intermediation concatenation or even supply support to the shadow banking entities. In add-on, shadow banking system operations provide tools that Bankss can utilize it to avoid ordinance or supervising applied to traditional bank system. Banks can interrupt the traditional recognition intermediation procedure under lawfully independent constructions covering with each other. As good known, the operations that Bankss besieging capital and accounting regulations, reassigning hazards out the control of banking ordinance is the chief cause of the recent crisis.
2.2 The Repurchase Agreement ( Repo ) Market
2.2.1 The Repurchase Agreement ( Repo )
The most of import constituent in shadow banking is securitized debt, such as U.S. Treasuries, commercial paper, mortgage-backed securities ( MBSs ) , equities, and so on. Acharya and A-ncu ( 2010 ) reference that, by the 4th one-fourth of 2009, the sum of outstanding securitized debt in the United States totaled $ 11.6 trillion, about tierce of the full U.S. debt market, and much of this securitized debt is in the signifier of repurchase understandings. As mentioned before, shadow banking is seen to trust on sweeping support such every bit repo as the sedimentations issued by traditional Bankss, and even seen as more dependent on these beginnings of support than traditional Bankss are on sedimentations.
A repurchase understanding is a fiscal contract that market participants used it as a funding method to run into short and long term liquidness demands, in which one participant borrows hard currency from the other by plighting a fiscal security as collateral. It besides known as a sale and buy back understanding for a two portion dealing, originally the bank or borrower, and the depositor or loaner. In instance that repo is negotiated and executed in private between a borrower and a loaner, it is referred to as a bilateral understanding. And when both participants to a repo portion a common keeper to keep collateral and to reassign hard currency, the agreement is referred to as a tri-party repo.
The depositor deposits money and earns involvement, whereas the bank provides bonds as collateral to endorse the sedimentation in exchange for the hard currency. Regulative alterations in the 1980s made the repo market an attractive beginning of short-run, frequently nightlong, funding for primary traders to finance their places in the debt of the U.S. authorities, federal bureaus, corporations, and federal bureau mortgage-backed securities. Subsequently, it besides became a support beginning for investors to impart and put in comparatively illiquid mortgage-backed securities.
When a repo dealing is agreed, hard currency will interchange for collateral on both the colony and the adulthood. The sale monetary value for the constitution of securities peers to the sum of hard currency Lent to the borrower, and the repurchase monetary value is tantamount to the sale monetary value plus involvement charged by loaner. Typically, the loan sum is tantamount to the market value of the collateral minus a haircut, in which the haircut is a per centum that calculated to protect the loaner in the instance of default by the borrower.
Figure 2.1 shows the hard currency exchanges in an “ nightlong ” bilateral repo that settles on the twenty-four hours after the trade and matures on the twenty-four hours after colony, and Figure 2.2 illustrates the function of a tri-party agent in keeping the borrower ‘s collateral and reassigning the loaner ‘s hard currency.
Repo is an nonprescription ( OTC ) contract that portions many cardinal characteristics with derived functions, such as the trust on its opposite numbers to run into duties over clip. Similar as all OTC merchandises, the life rhythm of repo contains several standard procedures: certification, executing, glade, colony, and detention. Figure 2.3 shows the life rhythm of repo.
The measure of glade is the lucifer of trade notices generated by the two participants and the induction of colony instructions for the motion of hard currency and securities. Uncluttering happens several times during the life rhythm of a trade: traders match trades between themselves and their clients, and depositaries match the ensuing colony instructions.
Colony of repo is the exchange of hard currency and collateral. Detention is the care of the hard currency and collateral in two separate histories for both the loaner and the borrower, which are held by broker-dealers themselves, by detention Bankss stand foring either party to the dealing, or by a individual bank functioning as keeper for both parties at the same time.
2.2.2 Repo Market in the U.S.
In 1917, the redemption understandings were foremost introduced to the U.S. fiscal market by the Federal Reserve. As Acharya and A-ncu ( 2010 ) reference, the Fed used repos secured with bankers ‘ credences to widen recognition to traders to promote the development of a liquid secondary market for credences. Early repos in the U.S. had two distinguishing characteristics. First, accrued involvement was excluded from the monetary value of the repo securities. Second, even though the creditor could sell or present the repo securities to settle a anterior sale at monetary values that included the accumulated involvement during the term of the repo, ownership of the repo securities rested with the debitor.
Figure 2.4 lists the chief alterations in the U.S. repo market history, the last important alteration before the current crisis is that Congress enacted the Bankruptcy Abuse Prevention and Consumer Protection Act of 2005 ( BAPCPA ) , which expanded the definition of redemption understandings to include mortgage loans, mortgage-related securities, and involvement from mortgage loans or mortgage-related securities, which make repo minutess eligible for bankruptcy safe seaport protection based on any stock, bond, or other security.
In the U.S. repo market, loans are largely drawn-out overnight, which constitute about half of all repo minutess, and most of them are unfastened, which means that they roll over automatically until either party chooses to go out. Other repo minutess called term repos, have footings longer than one twenty-four hours but shorter than one twelvemonth, while most adulthood of them three months or less. Participants in the repo market include commercial Bankss, investing Bankss, hedge financess, common financess, pension financess, money market financess, municipalities, corporations, and other proprietors of big sums of idle hard currency, every bit good as the Fed and primary securities traders.
The Fed participates in the repo market largely to implement its pecuniary policy, while primary securities traders participate chiefly to finance their market-making and hazard direction activities. Owners of big sums of hard currency in the repo market chiefly prosecute for two grounds: First, acquire better involvement rates in the repo market compared with sedimentations at commercial Bankss. Second, for insurance intents. Large sedimentations at commercial Bankss are non insured, whereas sedimentations at “ repo Bankss ” are secured by debt used as collateral.
The rapid growing of money keeping by institutional investors, pension financess, common financess, provinces and municipalities, and non-financial houses is one of the chief drivers of increasing usage of repos. They are seeking for a safe investing which can gain involvement and at the same time have strong liquidness. Under the U.S. Bankruptcy Code, particularly since the alteration in 2005, repos have a particular position: repo contract allows either participant to implement the expiration commissariats of the understanding one-sidedly if a bankruptcy filing by the other participant. Figure 2.5 shows the institutional investors ‘ fiscal assets in the United State from 1980 to 2008.
Unfortunately, there is no official statistics of the overall size of the repo market in US, the Fed merely counted the repo contracts that completed by the primary security traders trade with the Fed. Figure 2.6 indicates one-year norm of Daily funding by U.S. authorities primary traders from 1996 to 2011, and it can be seen that there is an exponential growing in repo market.
Hordahl and King ( 2008 ) study that repo markets doubled in size from 2002 to 2007, the paper indicate that with gross sums outstanding at year-end 2007 of approximately $ 10 trillion in each of the US and euro repo markets, and another $ 1 trillion in the UK repo market. They besides point out that the U.S. repo market exceeded $ 10 trillion in mid-2008, including dual numbering both repo and contrary repo in the same dealing. Gorton ( 2010 ) illustrate that the size of repo market in US is likely to be about $ 12 trillion as of 2009, compared with the entire assets in the U.S. banking system of $ 10 trillion.
In add-on, the tri-party repo is preponderantly portion in the US repo market, anecdotal grounds suggests that tri-party repo activity may account for between 65 % and 80 % of the overall US repo market. Figure 2.7 shows the growing of tri-party repo minutess from May 2002 to May 2010. The value of securities financed by tri-party repos grow swimmingly since 2002, reached the extremum to about $ 2.8 trillion in early 2008, so the size of the market has declined notably to $ 1.7 trillion during first-quarter in 2010.
Chapter 3. Literature Reappraisal
The term “ shadow banking system ” was foremost coined by former Pacific Investment Management Company ( PIMCO ) executive Paul McCulley at Federal Reserve Bank of Kansas City ‘s Economic Symposium in Jackson Hole Wyoming in 2007. McCulley ( 2010 ) said that the shadow banking system appeared with the development of money market financess in the 1970s, the money market accounts function similar as bank sedimentations, but money market financess non regulated as Bankss. Gertler and Boyd ( 1993 ) and Corrigan ( 2000 ) are early treatments of the function of commercial Bankss and the market based fiscal system in fiscal intermediation.
Paul Krugman ( 2008 ) of the New York Times trace the cause of the economic meltdown to a “ tally ” on shadow Bankss when recognition dried up. He argued that the shadow banking system rely on complex fiscal design, avoid the conventional fiscal ordinance and take portion in more commercial banking concern. Because of non regulated, shadow Bankss are easier to spread out concern countries than traditional Bankss, the fiscal crisis leads people to reassign their money from the shadow banking system to authorities bonds, all of a sudden the shadow Banks ‘ liquidness exhaustion.
3.1 Literature on Shadow Banking System
After the terror of 2007, there are a figure of academic surveies focus on the shadow banking system, and point out that the shadow banking system is at the bosom of the recognition crisis. Pozsar ( 2008 ) cataloguizes different types of shadow Bankss and describes the plus and support flows within the shadow banking system. The paper clearly presents how the collateralized debt duties ( CDOs ) changed from tools to pull off recognition hazard to a beginning of recognition hazard.
Adrian and Shin ( 2009 ) focal point on the function of security agents and traders in the shadow banking system, and discourse the deductions for fiscal ordinance. The paper illustrates that securitization was ab initio intended to be a manner to reassign recognition hazard to something better able to absorb losingss, but alternatively it increased the breakability of the fiscal system. It allows Bankss and other mediators to leverage up by purchasing each other ‘s securities. They point out that it is of import to forestall inordinate purchase and adulthood mismatch, which can sabotage the stableness of full fiscal system.
Pozsar, Adrian, Ashcraft, and Boesky ( 2010 ) supply a overview of shadow banking establishments and activities, focal point on support flows in a slightly mechanical mode. The paper outline the economic function of shadow banking and show that there is a deep connexion between shadow banking system and traditional banking system. The writers expect the shadow banking to be a important portion in the fiscal system in the hereafter, but in a different signifier.
Gorton and Metrick ( 2010a ) nowadays a good description of the shadow banking system and discourse its hazards to fiscal stableness. The analysis focal point on three major establishments: money-market common financess ( MMMFs ) , securitization and redemption understandings ( repos ) . They argue that the alteration that makes repo a bankruptcy safe seaport was important to the growing and efficiency of shadow banking, regulators can do usage of the entree to this bankruptcy safe seaport as the breach to implement new ordinances.
Gennaioli, Shleifer and Vishny ( 2011 ) develop a theoretical account of shadow banking where mediators originate, securitize and trade loans, financed externally with risk-free debt. As a consequence, adulthood transmutation and purchase are inordinate, and lead to recognition roars and flops when investors and mediators neglect tail hazards. Therefore, the paper argued that regulators should continuously supervise mediators ‘ exposures and fiscal inventions and intervene when necessary.
3.2 Literature on Repurchase Agreements ( Repo )
There are increasing figure of literatures on markets for redemption understandings ( repo ) since the terror of 2007 broke out. Before that, surveies on repo chiefly concentrate on the plus pricing field, e.g. Duffie ( 1996 ) and Buraschi and Menini ( 2002 ) . After the 2007 fiscal crisis, the research workers started to discourse the function of repo in shadow banking system, and its part to recent fiscal crisis. Most of the researches are based on the grounds of the U.S. repo market.
Many theoretical surveies have shown that pro-cyclical borders and haircuts have strong negative impact on the stableness of fiscal markets. Brunnermeier and Pederson ( 2009 ) develop a theoretical account where borders can increase in illiquidity given uncertainness over the nature of monetary value dazes. Once the speculators are capable to capital restraints, they will cut down their places and market liquidness autumn, which will so take to higher borders and a alleged liquidness spiral. They argued that regulators should better market liquidness by hiking speculator support conditions during a liquidness crisis. Jurek and Stafford ( 2010 ) provide financing footings in collateralized loaning markets with a theoretical theoretical account. The paper shows that securities which have rapidly worsening recovery values are financed at higher haircuts, will react much more strongly to market fluctuations. They argue that the hazard profile of the implicit in collateral entirely can explicate why the repo haircuts displacement massively during the recent fiscal crisis. Acharya, Gale and Yorulmazer ( 2011 ) present a theoretical account of market freezings and haircuts in secured adoption, which explain a chief characteristic of the crisis of 2007-2009: a sudden freezing in the market for short-run and asset-backed funding. The theoretical account contains three indispensable characteristics: the term of debts is much shorter than the assets and demands to turn over over often ; if the borrower default the contract, the collateral will be sold by the creditors and there is a little settlement cost ; and a important portion of possible purchasers of the collateral besides relies on short-run debt finance. Under these conditions, the debt capacity of the assets can be much less than the cardinal value, and in fact, equal the lower limit possible value of the plus. The paper argued that it is true even if the cardinal value of the assets is presently high. In peculiar, a little alteration in the cardinal value of the assets can be associated with a sudden prostration in the debt capacity. Other documents on this subject include Valderrama ( 2010 ) , Rytchkov ( 2009 ) , Geanakoplos ( 2010 ) .
Predictably, a great figure of empirical literatures based on grounds from the US repo market have turned up to corroborate the pro-cyclicality of borders and haircuts. The decision from these empirical surveies strongly show that alterations in borders and haircuts has a signally negative consequence on fiscal system.
Adrian and Shin ( 2010 ) showed that marked-to-market purchase is strongly procyclical, repo minutess have accounted for most of the pro-cyclical accommodation of the purchase of investing Bankss. In this paper, they argued that aggregative liquidness can be understood as the rate of growing of the aggregative fiscal sector balance sheet. Fiscal mediators ‘ balance sheets by and large become stronger when plus monetary values addition, their purchase tends to be excessively low, and so they hold excess capital. In this instance, the mediators will try to happen ways to use their excess capital. And for such excess capacity to be utilized, they must spread out their balance sheets, which means that they should take on more short-run debt on the liability side and hunt for possible borrowers on the plus side. From the grounds of repo market in the U.S. , it can be seen that when balance sheets are spread outing fast plenty, borrowers are granted recognition even they do non hold the agencies to refund, since the impulse to use excess capital is so intense. They point out that this is the cardinal cause for the subsequent diminution in the recognition rhythm.
Gorton and Metrick ( 2010b ) nowadays direct grounds on the haircuts in the repo market and exemplify that backdowns from securitized Bankss is the chief cause of addition in repo haircuts, which means that it is a bank tally. The paper said that when all investors involve in the tally and the haircuts rise high plenty, the securitized banking system can non finance itself and is forced to sell assets. These alterations in the restraints on support liquidness can hold a fast consequence on plus monetary values and market kineticss. As a consequence, the assets become information sensitive and the liquidness dries up, and eventually the system is insolvent.
Gorton and Metrick ( 2011 ) argued that one of the major cause of the 2007-2009 fiscal crisis was alterations in repo haircuts.The paper study a section of the bilateral repo market and utilize a fresh information set that includes recognition spreads for 100s of securitized bonds to follow the way of crisis from sub-prime-housing related assets into markets that had no connexion to lodging. They find that alterations in the “ LIB-OIS ” spread, a placeholder for counter-party hazard, was strongly correlated with alterations in recognition spreads and repo rates for securitized bonds, which implied higher uncertainness about bank solvency and lower values for repo collateral. Furthermore, they draw a figure demoing the haircuts index, which can be seen as an mean haircut for collateral used in repo minutess but non including U.S. Treasury securities, In the US repo market, mean haircut lifting from zero before July 2007 to about 50 per centum at the extremum of the fiscal crisis in late 2008. With decreasing plus values and increasing haircuts, the U.S. banking system was eventually insolvent for the first clip since the Great Depression.
However, Richard Comotto ( 2012 ) argued that there is a serious defect in this “ haircut index ” , every bit good as the thesis that much of the crisis was driven by “ run on repo ” . The paper point out that Gorton and Metrick ( 2011 ) ‘s informations based their decisions was merely for collateral in the signifier of structured securities ( ABS, RMBS, CMBS, CLO and CDO ) . Furthermore, the paper claim that Gorton and Metrick ( 2011 ) offer no information on US Treasuries, which constitutes the largest pool of repo collateral in the US, and disregard the tri-party section of the repo market, which may hold accounted for 50-60 % of outstanding U.S. repo and is mostly collateralized by U.S. Treasuries, Agencies and MBS, for which haircuts are much lower and plus values were non impacted by the crisis to anything like the grade as structured securities. The paper besides indicate that the Fed sponsored Task Force on Tri-party Repo Infrastructure ( 2009 ) reported that the available informations suggested that haircuts in the tri-party repo market did non alter much during the 2007-2009. In decision, Richard Comotto ( 2012 ) thought that Gorton and Metrick ( 2011 ) are unwise to presume that repo support is by virtuousness of the kineticss of haircuts is an inherently unstable beginning of support without sufficient empirical informations.
Copeland, Martin and Walker ( 2011 ) find that there are important differences between haircut alterations in bilateral and tri-party section of the repo market. During the 2007-2009 fiscal crisis, haircuts and support in the bilateral repo market changed dramatically which is similar with the consequence of Gorton and Metrick ( 2011 ) ‘s work. However, haircuts in the tri-party repo market did non alter much, and that support was really stable for traders, and the lone exclusion is Lehman Brothers, whose tri-party repo book decreased aggressively in the yearss taking up to its bankruptcy. The writer provide three possible accounts as to why haircuts in the tri-party repo market about maintain unchanged. First one is that some hard currency investors prefer to retreat support instead than take ownership of the collateral when they think a trader is non responsible. Second, since money financess are really intolerant of liquidness and recognition hazard, major classs of tri-party repo investors have to worry about backdown force per unit areas from their ain investors. Third, due to tri-party repos were chiefly nightlong and the glade bank would wind off repos every forenoon, hard currency investors may experience that they can ever draw away from troubled trader, which makes the direction of haircuts less of import.
Since tri-party repo market and the bilateral repo market were both at the bosom of the current fiscal crisis, to recognize the different usage of haircuts across these two repo markets is of import to regulators in sing policies designed to forestall tallies on securities traders. A farther survey from Martin, Skeie and von Thadden ( 2011 ) , develop a dynamic equilibrium theoretical account to analyze how the breakability of short-run support markets depends upon the peculiar microstructures, liquidness, and indirect agreements that may take to runs at assorted types of fiscal establishments. The paper shows that market microstructure can explicate the different alterations of haircuts between bilateral and tri-party repo markets. The haircut for each collateral category is included in the tutelary project understanding between the three parties and takes much more clip to alter than bilateral contracts, which make the tri-party repo market more susceptible to runs. The theoretical account can really explicate why haircuts may non set sufficiently to protect the investors in instance of Lehman Brothers.
Although several surveies believe that the tally on the repo market play a important function during the fiscal crisis, some empirical documents argue that the impact of repo contraction on the shadow banking system is comparatively limited. For illustration, Krishnamurthy, Nagel and Orlov ( 2012 ) step the repo support extended by money market financess ( MMF ) and securities loaners to the shadow banking system, including measures, haircuts, and repo rates by type of implicit in collateral. They suggest that repo merely played a really little function in funding private sector assets prior to the crisis, merely 3 % of outstanding non-Agency mortgage-backed securities ( MBS ) and asset-backed ( ABS ) securities was financed by repos from MMFs or securities loaners, and 22 % was financed by asset-backed commercial paper ( ABCP ) . However, they besides find that the contraction in repo peculiarly have systematical impact on cardinal trader Bankss with big exposures to private sector securities, which so had knock-on effects on security markets.
3.3 Literature on Repo Market Regulation
Gai, Haldane and Kapadia ( 2011 ) develop a web theoretical account of interbank loaning in which unbarred claims, repo activity and dazes to the haircuts applied to indirect assume centre phase. The theoretical account shows that how the complexness and concentration in fiscal system may magnify its breakability. The analysis non merely points out that minimal border demands can be used as a macro-prudential tool in ordinance, it besides suggests that how a scope of policy steps including liquidness ordinance and capital surcharges for systemically of import fiscal establishments could do the fiscal system more resilient.
Goodhart, Charles, Kashyap, Tsmocos and Varoulavis ( 2011 ) present a theoretical account that includes both a banking system and a “ shadow banking system ” that each aid families finance their outgos, and research how different types of fiscal ordinance could battle many of the phenomena that were observed in the fiscal crisis of 2007 to 2009. The paper analyses the effects of increasing border demands on repo minutess, and show that border limitations may partly restrain hazard pickings and raise the cost of mortgage adoption.
Gorton and Metrick ( 2010b ) suggest that repos should be regulated because they are, in consequence, new signifiers of banking, it is similar to bank sedimentations but have the same exposures as bank-created money. The writers ‘ proposals are aimed to make a sufficient sum of high quality collateral which can safely be used in repo minutess.
Acharya and A-ncu ( 2012 ) point out one of the regulative failures behind the recent fiscal crisis started in 2007 has been that the regulative exercising focal point on single, instead than systemic, hazard of fiscal establishments. Therefore, they provide a set of declaration mechanisms which is non merely capable of turn toing the issues of bring oning market subject and extenuating moral jeopardy, but besides capable of turn toing the systemic hazard associated with the systemically of import assets and liabilities ( SIALs ) . Specifically, in order to command the hazard of the tally on repo market, the writers propose to make a “ Repo Resolution Authority ( RRA ) ” in legal powers with important repo activities, which can turn to the outwardness of systemic hazard of repo contracts on risky and potentially illiquid collaterals.
Chapter 4. Repo in 2007-2009 Financial Crisis
4.1 The Crisis of 2007-2009
Due to the fact that the bulk of leveraged places in shadow banking was based on repo funding, it efficaciously observed that a tally on repos drama a important function in the fiscal crisis. Gorton and Metrick ( 2010 ) usage two chief variables to assist reexamine the timeline of the crisis: the ABX index, and LIB-OIS. The ABX index provides publically discernible market that monetary values sub-prime hazard, can be seen as a placeholder for basicss in the sub-prime mortgage market. The LIB-OIS, which is the spread between the three-month London Interbank Offered Rate ( LIBOR ) and the three-month nightlong index barter ( OIS ) rate, can be seen as a placeholder for counter-party hazard in repo minutess.
Figure 4.1 shows the ABX and LIB-OIS spreads, in which the ABX spread is the CDS spread on the BBB-rated ABX tranche of the first vintage of the ABX in 2006.
Harmonizing to the ABX index in figure, the sub-prime market start to deteriorate since the beginning of 2007, which had a direct impact on Bankss whoes equilibrate sheets had tonss of securitized assets and pre-securitized mortgages. Creditors started to inquire the two Bear Stearns financess to supply more collateral to endorse the repos, and when the financess unable to run into the calls, creditors led by Merrill Lynch threatened to declare the financess in default of repos and to prehend the investings. In fact, harmonizing to Acharya et Al. ( 2009 ) , Merrill seized $ 850 million of the CDOs and tried to auction them on June 19, 2007. However, when Merrill was merely able to sell about $ 100 million worth of CDOs, sub-prime assets ‘ illiquid nature and the worsening value emerged.
The rapid addition of the ABX spread during July 2007 appears to be a response of the sub-prime market to this run on the shadow Bankss in the repo market. The importance of the freedom of repos from the application of automatic stay becomes to emerge. The Bear Stearns financess can hold filed for bankruptcy and avoid the forced fire sale of their assets since their repo securities was capable to automatic stay, and the sub-prime mortgage diminution became systemic finally.
After maintaining unchanged in the first 6 months in 2007, LIB-OIS first signals danger with the first major leap in August, for the existent impairment in bank balance sheets in the interbank market. In period during July to September LIB-OIS reached and past its historical record 3 times, which is besides the period that the initial daze for a broad scope of the securitization markets, peculiarly in top-quality parts that normally used as collateral in the repo market.In early August 2007, a tally ensued on the assets of three structured investing vehicles ( SIVs ) of BNP Paribas. On August 9, BNP Paribas suspended salvations from these SIVs. BNP Paribas ‘s SIVs were bankruptcy-remote entities financing their sub-prime retentions through the issue of ABCPs that had basically lost their liquidness and go non-tradable. The proclamation of the suspension of salvations by BNP Paribas gave rise to counter-party hazard concerns and caused the ABCP market to stop dead, and This freezing coincided in the LIB-OIS spread. Fears of counter-party hazard spread through markets, all short-run debt markets-including the repo market-froze, merely to open after cardinal Bankss injected monolithic sums of liquidness into the system.
The LIB-OIS spread remained in a historically high until September 2008, when the events at Fannie Mae, Freddie Mac, Lehman, and AIG cause a rapid arrested development in interbank markets and sustained addition in the LIB-OIS until the terminal of 2008.
4.2 Repo Haircuts
A haircut of repo is a per centum price reduction deducted from the market value of a security which is being offered as a collateral in a repo in order to cipher the purchase monetary value. The expression for a haircut is as follow:
It counts to turn to the hazard that if the depositor of the bond in repo must sell a bond in the market to acquire the backdown, the bargainer to whom the bond is sold may be better informed and ensuing in a loss, which means that the monetary value may non set to turn to this hazard. In this instance, a haircut tranching the collateral to animate an information insensitive security and thereby better its liquidness. Gorton and Metrick ( 2010 ) suggest that the increasing haircuts in the interdealer repo market may be seen as a tally on shadow Bankss, it tantamount to a backdown from the publishing bank.
Figure 4.2 shows the haircuts for the non-sub-prime-related group, sub-prime-related groups, and the norm of all the classs from 2007 to 2009. The informations Gorton and Metrick ( 2010 ) examine are the interdealer repo haircuts for the undermentioned plus classesi?s ( 1 ) A-AAA ABS ( auto/credit cards/student loans ) ; ( 2 ) AA-AAA RMBS/CMBS ; ( 3 ) below-A RMBS/CMBS ; ( 4 ) AA-AAA CLO ; ( 5 ) unpriced ABS/MBS/all sub-prime ; ( 6 ) AA-AAA CDOs ; ( 7 ) unpriced CLOs/ CDOs. Of these categories, ( 1 ) through ( 4 ) are non sub-prime related since they do non incorporate sub-prime mortgages. The RMBS in classs ( 2 ) and ( 3 ) are premier mortgages, non sub-prime. Classs ( 5 ) through ( 7 ) are either straight sub-prime or incorporate sub-prime mortgages. in peculiar, CDOs contain some sub-prime mortgages. Gorton and Metrick ( 2010 ) use all seven classs to build an every bit leaden mean repo haircut index for structured bonds.
Figure 4.2 illustrates that in the period of 2007 to 2009, the repo haircuts increased from nothing in early 2007 to about 50 per centum in late 2008 on norm. Haircuts were higher on sub-prime-related plus categories, it finally went to 100 per centum haircuts, which means these assets were non acceptable in repo as collateral, whereas the non-sub-prime-related plus categories reached a extremum at 20 per centum. In order to assist understand the impact of “ run on repo ” , for case, take entire size of the repo market to be $ 10 trillion. Then, if the mean haircut goes from zero to 20 per centum during the crisis, which means that the securitized banking system must lift $ 2 trillion from other beginnings to fund its assets. In this instance, the merely available manner for Bankss to do up the difference was sale the plus, which caused a farther diminution in the monetary values of these plus categories, doing them less useable as collateral, so further gross revenues, and so on. Furthermore, Figure 4.2 besides shows a loss of assurance through the haircut growing in the non-sub-prime-related group even though it had nil to make with sub-prime mortgages.
It is deserving detecting that Gorton and Metrick ( 2010 ) ‘s informations ignore the tri-party section of the repo market, and harmonizing to the Task Force on Tri-party Repo Infrastructure White Paper ( 2010 ) , the available informations suggested that haircuts in the tri-party repo market about remain unchanged during 2007 and 2009. However, it does non intend tri-party repo had nil to make with the crisis. FRBNY White Paper ( 2010 ) claims that “ ( a ) T several points during the fiscal crisis of 2007-2009, the tri-party repo market took on peculiar importance in relation to the failures and near-failures of Countrywide Securities, Bear Stearns, and Lehman Brothers. The potency for the tri-party repo market to discontinue operation, with impacts to securities houses, money market common financess, major Bankss involved in payment and colonies globally, and even to the liquidness of the U.S. Treasury and Agency securities, has been cited by policy shapers as a key concern behind aggressive intercessions to incorporate the fiscal crisis. ”
4.3 The Transparency of Repo
Security funding market is complicated, evolved quickly and sometime can be opaquely for some market participants and regulators. The transparence may, every bit good, be missing due to the bilateral nature of securities financing minutess. During the fiscal crisis, the deficiency of transparence is embodied in several degrees:
Market informations on macro degree: old to the current crisis, some governments faced troubles in valuating and oversing the hazards on certain angles of the markets. There are merely some available informations from information sellers that collect information from mediators for commercial intents, or based on studies presented by the governments or trade associations. Particularly in bilateral and man-made minutess, the deficiency of transparence is much more terrible since there is no market informations available and governments have to trust on market intelligence.
Market informations on micro degree: due to the fact that securities imparting and repo are constructed in assorted ways, without exact informations on dealing degree, it might be hard to prehend the existent hazards that individual market participants pose to the system, particularly for the bilateral minutess.
Corporate revelation by market participants: in most governments, cash-versus-securities minutess are normally reported on-balance sheet. However, harmonizing to the accounting criterions used in some instances, repos can be reported off-balance sheet, or even revelation is provided in fiscal histories of securities-versus-securities minutess, that are typically “ looked through ” for the intent of fiscal study. The battle of fiscal establishments in off-balance sheet minutess without sufficient revelation may lend to their risk-taking inducements and finally increase the breakability of the full fiscal system.
Hazard coverage by mediators to their clients: old to the current crisis, a figure of premier agents had non provide equal revelation on re-hypothecation activities to their hedge fund clients. After the prostration of Lehman Brothers International, for case, many hedge financess turned into unbarred general creditors out of the blue since they did non realized that the extent to which it had been re-hypothecating client securities. Furthermore, some securities loaners, peculiarly some less sophisticated loaners who have claimed that they were non adequately informed by the agent loaners about the counter-party hazard and hard currency collateral reinvestment hazard of their securities loaning activities.
4.4 Role of Repo during the Crisis
Repo played a important function in each phase of the fiscal crisis, from investor hurt in early 2007 to the prostration of major fiscal establishments at the extremum of the crisis in October of 2008. ICMA ‘s Europe European Repo Council ( 2012 ) lineation and discourse several possible functions that repo played during the current crisis:
4.4.1 Excessive Leverage
In theory, repo can let infinite purchase. For illustration, a house finance the purchase of an plus with its ain financess ab initio, so it could repo out the assets to borrow hard currency and utilize the hard currency to purchase more assets, and it repos out for more hard currency and so on. However, the hazard of collateralized funding promoting inordinate purchase is slightly mitigated by the existent universe restraints on over-borrowing, which apply to both unbarred and secured instruments. This is why Lehman Brothers perpetrated Repo 105 and why MF Global employed repo-to-maturity. And although adoption degrees are merely disclosed sporadically with a slowdown and amiss, participants in both the unbarred and secured money markets conduct real-time examination of each other ‘s adoption in order to observe forms of behaviour that suggest an unusual hungriness for liquidness. It is a gross misinterpretation of the nature of repo that collateral makes loaners apathetic to counter-party recognition hazard.
Some Bankss have over-leveraged, utilizing both unbarred and secured funding. So, some kind of restraint can be justified. But a compulsory haircut to move as a type of fractional modesty is unwanted, as it would falsify the comparative pricing of secured versus unbarred instruments. It would besides be a really blunt tool, which would cut down liquidness across the full market, to cover with what should be seen as a job of hazard direction particular to single establishments. General instrument-based attacks are more likely to hold unexpected effects. And, as a affair of rule, concerns about establishments taking inordinate purchase should be addressed straight utilizing institution-specific tools such as purchase bounds and capital ratios.
4.4.2 Encumber Assetss
Traditionally, burden is a job originating from the pledging of collateral, which may be caused when assets are provided as collateral by a borrower. Although those assets still looking on the borrower ‘s balance sheet, they are no longer available to assist run into the claims of unbarred creditors in the event of the insolvency of the borrower. Now repos such as collateral barters have started to be seen as a beginning of burden.
Burden might originate where repo collateral is capable to an haircut. In this instance, it can be argued that the assets represented by the haircut are encumbered, as their sale is non compensated by hard currency. Hence, it would look that haircuts structurally subordinate the claims of unbarred creditors over assets given as collateral. However, it should to be remembered that haircuts are non universally applied nor are they are important in size.
The job can originate where haircuts are deep, for illustration, in long-run repo and collateral barters, over-collateralization could be seen as giving rise to burden. However, the giving of the haircut in such minutess is typically compensated by the purchaser plighting the haircut back to the marketer, which eliminates any burden. Therefore, the issue of the burden of assets by repos is mostly illusive.
4.4.3 Amplify Pro-cyclicality
Regulatory concerns that market patterns in puting haircuts aid to magnify fiscal market pro-cyclicality envisage a haircut-asset rating spiral as the elaboration mechanism. In an up-cycle, ample liquidness, low volatility, lifting plus values, high recognition evaluations and strong competition for concern erode haircuts, lending to the growing in purchase. When an sum daze triggers the start of a down-cycle, haircuts are increased in response to the initial loss of assurance. In the mode of a recognition multiplier in contrary, this reduces the liquidness of market users who sell assets in response. Asset gross revenues cut down the value of collateral, doing haircuts to be increased once more. And so on. Each market user is acting rationally from its point of position but, in sum, their single actions create a negative systemic outwardness. This type of scenario has given rise to the broader claim that the market crisis of 2007-09 was basically, if non wholly, a “ tally on repo ” and that repo is an built-in, unstable beginning of support.
However, the regulative argument has been taking topographic point mostly in the absence of sufficient empirical informations on haircuts use or possible impact. Estimates of the likely impact of alterations in haircuts on the liquidness of the European repo market between 2007 and 2009, utilizing available informations on market size and composing, suggest that their systemic impact may be comparatively undistinguished in footings of the de-leveraging that took topographic point over this period, which earnestly undermines the statement that repo is, by virtuousness of haircuts, an inherently unstable beginning of support.
Chapter 5. Regulations in Repo Market
5.1 Current Regulatory Framework of Repo Market
FSB ( 2012 ) provides a high-ranking sum-up of the consequences of a study in fall 2011, conducted by the FSB Workstream on Securities Lending and Repos and the International Organization of Commissions ( IOSCO ) Standing Committee on Risk and Research, which maps the current regulative models based on the responses from 12 member governments ( Australia, Brazil, Canada, France, Germany, Japan, Mexico, the Netherlands, Switzerland, Turkey, U.K. and U.S. ) , the European Commission, and the European Central Bank ( ECB ) . Figure 5.1 lineation the chief regulative alterations in 12 legal powers on different facets:
5.1.1 Requirements on Financial Intermediations
Typically, hazard exposures originating from securities imparting and repo minutess are taken into history in the regulative capital government for Bankss and broker-dealers. Under the Basel capital government, for case, Bankss are requested to keep capital against any counter-party exposures cyberspace of the collateral from repo or securities loan associated with an add-on for possible hereafter exposure. Internet of the collateral, nevertheless, is allowed merely when the legal understanding is enforceable under appropriate Torahs. As good, capital demands must be held against Lent or repoed securities continuously.
Furthermore, some other demands that subject to Bankss and securities agent traders are designed in order to better hazard direction and strengthen protection on investors. Unlike consistent regulative capital demands that has been applied across governments, there are a assortment of tools and inside informations each authorization has adopted harmonizing to the hazards that they need to cover with.
5.1.2 Requirements on Investors
Due to the fact that hazard exposures originating when investing financess and insurance companies involved in the securities loaning and repo markets as investors, it is necessary to plan relevant regulative demands and activity limitations to modulate such fiscal establishments, every bit good as protect single investors.
Counter-party recognition hazard, which originating from securities imparting and repo minutess, can be alleviated by limitations on eligible counter-parties and counter-party concentration bounds. Concretely, it can be regulated from two facets: foremost, curtailing eligible counter-parties for securities loaning and repo minutess ; 2nd, utilizing counter-party concentration bounds to relieve the consequence of a big counter-party ‘s default.
Liquidity hazard, originating from securities imparting and repo minutess for insurance companies and MMFs. Some governments restrict the adulthood of securities loans and repos in order to relieve the liquidness hazard. Such adulthood bounds range from 30 yearss to around one twelvemonth.
Collateral guidelines, some legal powers have introduced indirect guidelines that apply either by and large or specifically to securities loaning and repos, which include assorted regulative tools such as lower limit borders and haircuts, eligibility standards for collateral, limitations on re-use of collateral and re-hypothecation, and limitations on hard currency collateral reinvestment.
Transparency, which are similar to the general demands for public revelations and regulative coverage. One exclusion is that U.S. petition insurance companies who involved in securities imparting plan to register extra revelation in reinvested collateral by specific plus classs and emphasis testing. These revelations will emphasis the continuance mismatch and coerce the company to explicate how they would pull off the unexpected liquidness demands.
5.2 Deductions for Further Regulation on Repo Market
Presently, fiscal ordinance chiefly concentrate on two distinguishable activities: proctor single establishments ‘ impact on system stableness, and the protection of investors. For repo market ‘s systemic nature and structural failings, nevertheless, regulative exercising on repo market should concentrate more on systemic hazard of fiscal establishments, instead than persons.
Acharya and A-ncu ( 2012 ) reference that unless the systemic liquidness hazard of repo market is resolved, the hazard of a tally on the repo market will still stay. They point out that unlike the unbarred liquidness hazard that funding may go unavailable to a house, the secured liquidness hazard that repo funding may go unavailable to a house is inherently a systemic hazard. In other words, markets for the repo securities may be illiquid when most portion of fiscal sector is undergoing undercapitalization or support emphasis. In good times, fiscal houses may non to the full internalise the costs imposed on the system by being overly financed through short-run repo markets, whereas in bad times, they charge overly high haircuts on repo funding and do non internalise the monetary outwardnesss imposed on other houses through the resulting fire gross revenues of assets. In this instance, it should be concern that whether to back up fiscal houses confronting a repo freezing or to back up the assets straight. On one manus, it can subject repo-financed hazardous securities to a efficaciously regulative haircut, which takes into history the security ‘s systemic hazard and adulthood mismatch relation to the repo tenor. On the other manus, it can take a better design of the bankruptcy of a repo-financed debitor than merely allowing its repo moneyman the full right to prehend the collateral and neutralize it at will in an illiquid market.
Haircuts are widely seen among regulators and faculty members as lending to the instability of the repo funding. There is a argument as to whether larger and more stable haircuts should be imposed on the repo market in order to stifle valuation-induced pro-cyclicality in stressed market conditions, peculiarly for indirect assets that are prone to rating uncertainnesss. This could be done straight or by the infliction of a countercyclical addition to capital charges on secured loaning to hike haircuts during up-cycles. As the paper of ICMA ( 2012 ) references, even if haircuts are mandated to stay stable over the concern rhythm, there are other loaning footings that could be used to increase the handiness of recognition during periods of optimism and restrain recognition during periods of de-leveraging, with potentially some of the same pro-cyclical effects on fiscal markets as that of variable haircuts
Furthermore, regulators besides need to see that whether mandated minimal haircuts can be sufficiently flexible to expeditiously embrace the broad scope of combinations of collateral, contract and counter-party that are possible in repo. A policy of one-size-fits-all compulsory haircuts hazards falsifying the market and making rigidnesss that will further unreal arbitrages. As a affair of rule, concerns about inordinate purchase would best be addressed at house instead than dealing degree, by the direct ordinance of purchase without concern its beginning. In add-on, the proposal that encourage of more frequent and efficient border care to smooth out collateral calls seems more helpful than mandated minimal haircuts.
Chapter 6. Decision
This paper chiefly focus on two facets: discourse the function of repo in the current fiscal crisis, and sketch the deductions on repo market ordinance. As the former comprehensive literature study on this subject shows that there is no exact reply on what is the chief cause for the current crisis and the regulators are still. In this paper, the survey merely give to supply a ocular apprehension on repo market in the 2007-2009 fiscal crisis.
As mentioned above, repo is the important portion of the shadow banking system, every bit good played an of import function in the current crisis. However, since the deficiency of official statistics, there still remains debate on whether “ run on repo ” is the chief cause of the crisis. Furthermore, repo has been viewed as a beginning of plus burden, has the leaning of collateralized funding to promote inordinate purchase, and the possibility in amplify pro-cyclicality.
On the facet of ordinance, after a brief overview of the regulative model in repo market, it can be seen that current fiscal ordinance chiefly focus on single, instead than systemic hazard. A efficaciously regulative haircut, which takes into history the security ‘s systemic hazard and adulthood mismatch relation to the repo tenor, might be a good pick to pull off the hazard in repo-financed securities. However, regulators need to see that whether mandated minimal haircuts can be sufficiently flexible to expeditiously embrace the broad scope of combinations of collateral, contract and counter-party that are possible in repo. As a affair of rule, concerns about inordinate purchase would best be addressed at house instead than dealing degree, by the direct ordinance of purchase without concern its beginning.
