The CDS discussed above transfers the credit risk of a single entity from the protection buyer to the protection seller for a contracted period. Where protection buyers seek to securitize large portfolios of default risk prone loans, or even CDSs, the collateralized debt obligations (CDO) is used.
How is a loan portfolio different from a single loan? We have seen above that the individual firms (in a loan portfolio) could default, leading to losses in the portfolio value. This risk can be assessed by estimating the PD for each firm and the LGD (1 – RR). Additionally, the degree of dependence in the portfolio between firms’ default probability, known as ‘default correlation’, has an impact on the timing of firms’ default, and, therefore, on the portfolio loss.
Understanding the CDO We have seen in the previous chapter that a CDO, like securitization, is a way of creating securities with differing risk characteristics from a portfolio of debt instruments.
However in a CDO, the portfolio comprises of heterogeneous instruments, such as senior secured bank loans, CDSs or high yield bonds (in securitization, it is typically a homogeneous pool of, say, home loans, auto loans, etc.). The basic structure of a CDO is as given in Figure 9.14.
Bank A, owner of a loan portfolio, wants to protect itself against the possible losses in the portfolio, but it does not want to ‘sell’ the portfolio. One way is to buy CDS for each borrower/firm in the loan portfolio, but that would be quite expensive. Further, individual CDS contracts do not protect against correlated defaults.
Bank A decides to buy protection through a CDO. In a typical CDO, the portfolio’s risk is ‘sliced’ into ‘tranches’ (‘tranche’ in French, means ‘slice’ and, in simple terms, every tranche is akin to tradable commercial paper) of increasing seniority and default risk of the underlying pool of loans (or CDSs).
Thus, each tranche in a CDO shows the priority of receiving payments from the underlying pool of assets, and also bearing the default risk. Each tranche is sold separately to investors according to their risk preferences, for a fee.
Cash flows are the critical link between the asset and liability sides of the CDO transaction. The asset side of the CDO is the underlying portfolio of reference assets—loans (or CDSs). The liabilities side comprises the securities issued by an issuer, which is typically a special purpose vehicle (SPV) that is a separate company or trust specially created for the transaction by the owner of the pool of assets. The SPV is created to insulate potential investors from the risk of failure of the CDO originator itself, say a bank.
Bank A, the originator of the CDO, sells the selected portfolio of assets whose credit risk is to be transferred, to the SPV, which in turn issues structured notes in the market backed by the portfolio of assets.
Let us now understand Figure 9.14. The first tranche (called the ‘equity tranche’) holds 5 per cent of the total notional loan principal, and absorbs all credit losses from the portfolio (during the life of the CDO) until the losses aggregate to 5 per cent of the notional principal. Hence the equity tranche is also called the ‘first loss tranche’, if the losses exceed 5 percent; the second tranche, which has 10 per cent of the loan principal, absorbs losses up to a maximum of 15 per cent (cumulatively). The third tranche holds 15 per cent of the principal and absorbs losses over 15 per cent up to a maximum of 30 per cent of the principal. The fourth tranche holds the bulk of the loan principal, 70 per cent, and absorbs all losses exceeding 30 per cent of the principal.
FIGURE 9.14 THE BASIC CDO STRUCTURE
Now look at the yields (rate of interest paid) to the respective tranche holders. These rates are paid on the notional principal remaining in each tranche after the losses have been paid. Assume that tranche 1 suffers a loss of 1 per cent. The tranche holders, who were paid 40 per cent in case of no default, would now lose 20 per cent (1/5) of their investment, and would earn only on the remaining 80 per cent of their investment. Since they assume the first loss, taking the maximum risk, they are called the ‘equity tranche holders’. If the default loss were to rise to 3 per cent, this tranche would lose up to 60 per cent of the notional principal. Compare this with tranche 4. Defaults on the portfolio must exceed 30 per cent if this tranche is to suffer losses. Hence, this tranche is usually given the top rating (say AAA) by rating agencies. Since this is relatively safe investment, the tranche earns less for its holders. It is usual for Bank A, the originator of the CDO, to retain the equity tranche. The remaining tranches are sold in the market.
The transaction in the above example is termed ‘cash CDO’.
Typically, four broad types of CDOs are recognized—cash flow CDOs, market value CDOs, managed CDOs and static CDOs. The attributes of a specific CDO, such as MTM, rules related to trading of the underlying securities, etc., are determined by the type of CDO. For example, in a cash flow CDO, payments to investors are in the form of interest earnings and principal repayments from the underlying assets. Erosion in the underlying asset values would not usually have an impact on the cash flows to the investors in the CDO, unless the erosion is accompanied by a credit event. In this case, the interest/principal payments cease to flow from the asset originators to the SPV, leading to lower cash flow for the CDO investors. In the case of the market value CDO, changes in the MTM value are passed on to the CDO investors through the SPV.99 In a managed CDO, the CDO manager actively trades the securities in the pool, with performance being monitored by the investors. In contrast, the static CDO’s portfolio is determined upfront and does not change over time.
If the portfolio of loans in the example is replaced by a portfolio of CDSs, the CDO is termed ‘synthetic CDO’.
Cash inflows to the synthetic CDO are the underlying CDS premiums, and cash outflows are losses consequent to credit events related to the underlying assets. Each tranche in a synthetic CDO has a specified upper and lower ‘detachment’ (U) and ‘attachment’ (L) point. Defaults affect the tranche according to the seniority of the tranche in the capital structure. The buyer of the tranche with attachment point L and detachment point U will bear all losses in the portfolio value in excess of L and up to U per cent of initial value of the portfolio. Table 9.13 presents the typical tranching done in the iTraxx index (Please see Box 9.10 for an introduction to credit indices).
TABLE 9.13 A SAMPLE CDO TRANCHED STRUCTURE, ITRAXX100
Assume that the above CDO experiences a 12 per cent loss of its initial value. This implies that the equity tranche holders will bear up to 10 per cent of the loss while the junior mezzanine holders would bear the remaining 2 per cent. The holders of more senior tranches (senior mezzanine, junior senior, super senior) will not suffer any loss. The super senior suffers only if the total collateral portfolio loss exceeds 35 per cent of its notional value.
Hence, it can be seen that CDO tranching enables holders of the respective tranches to limit their loss exposure to (U – L) per cent of the initial portfolio value.
For example,101 assume a hypothetical CDS index comprises of 100 names with equal weight (1/100) for each name. The tranches are indicated in the market as follows: 0–5, 5–10, 10–15, 15–22, 22–100. In other words, the 10–15 tranche has an attachment point L of 10 and a detachment point U of 15 and so on. We assume a specific investor has bought protection on the 0–5 per cent tranche with a notional principal of ₹10 crore. If one name out of the 100 defaults, and recovery is set at 65 per cent, the LGD is 35 per cent. In such a case the payout from the protection seller would be calculated using the formula—(notional principal × LGD × weighting)/tranche size, i.e., a payout of ₹70,000. Once the payout happens, the 025 tranche is recalculated to reflect the reduced notional principal. Hence 4.65 per cent (5 – 0.35 LGD) of the notional principal remains, which implies that the new detachment point should reflect that only 99 names now remain in the CDO. The new detachment point has to be now adjusted for the remaining names in the Index. It is to be noted that the original principal of the other tranches are not impacted due to this change, but have less protection against further losses.
The same concept can be used for determining the number of credit events at which the equity tranche stops covering losses, and the next tranche starts losing. The loss level in any given tranche depends on two random variables—the number of credit events in the entire portfolio and the related LGD. Assuming the LGD of 35 per cent in the previous paragraph applies to all defaulted firms in the portfolio (in reality LGD for each asset may be uncertain), the scenario under which the equity holders lose their entire notional principal (i.e., when the equity tranche gets fully written down to zero) will be given by the equation n number of defaults × ₹10 lakh per name notional × 35 per cent loss rate = 5 per cent equity tranche width × ₹10 crore million total portfolio notional.
Solving for n yields 14—the number of defaults for the equity tranche to be written down to zero. This means that the portfolio would have lost ₹50 lakh, at which point the equity tranche would be fully written down to zero. The next tranche, say, the junior mezzanine, would start losing from the 15th default onwards, and so on.
Pricing the CDO The concept of ‘default correlation’ is important to determine the pricing of a tranched CDO, such as tranched iTraxx.
For any two given firms, their default correlation approximates to a measure of the correlation between the times at which they default. In other words, two reference assets or firms which are highly correlated (correlation close to 1) are likely to behave similarly—either defaulting or not defaulting, together. This implies that a portfolio with several reference assets, who bear a high default correlation with one another, will have higher probabilities of both higher and lower loss rates. Consequently, the emanating loss distribution is likely to have fatter tails.
As default correlation increases in a portfolio, it is easy to understand why the cash flows from the underlying asset pool of loans or CDS would exhibit higher volatility. As volatility increases, the market value of the equity tranche (the highest risk bearing tranche) increases (and the spread decreases). On the other hand, since increased volatility (risk) is not favoured by the senior most tranche, the market value declines with an increase in default correlation, leading to higher spreads. The mezzanine and other tranches in between these two can have exposures to correlation in either direction, depending on the degree of volatility.
The basic methodology is to average the discounted cash flows to a particular tranche over several independently simulated scenarios. This implies that cash flows for each underlying single name CDS in the CDO have to be simulated, with correlation in the default times of the various underlying firms as well. The widely used industry methodology for the correlated default time simulation is the ‘Gaussian copula’ (in Statistics, ‘copula’ is used to couple the behaviour of two or more variables—however, a discussion on this is outside the scope of this book).102
Box 9.10 introduces credit indices developed in credit derivative markets.
It is obvious from the discussion this far that CDOs were created and customized to meet specific needs of investors and credit risk transferring institutions. However, customization also means higher cost—creating exclusive SPVs, legal documentation and approvals, managers to design and oversee trade in the CDO and so on. The primary advantages of indices over customized CDOs are (1) liquidity, since issue sizes are large with varying credit spreads, (2) transparency (easier to obtain price quotes and information on pricing and spreads—rules, constituents, fixed coupon and daily prices are publicly available), (3) cost (lower transaction costs due to possibility of trading in portions of the market and standardization), (4) tradability, (5) operational efficiency (standardized terms, legal documentation and electronic processing) and (6) industry support (most major dealer banks and other players use and support the indices).
The standardization also contributed to better hedging patterns. For example, before the introduction of indices, issuers would hedge unbalanced positions of customized CDOs through even more complex, multi-tranche structures. This made the transaction even less transparent.
The Evolution
2001 saw the launch of synthetic credit indices by J. P. Morgan (JECI and Hydi), and Morgan Stanley (Synthetic TRACERS). Subsequently, in 2003, these indices were merged under the name Trac-x. At around the same time, credit derivative indices were introduced by iBoxx. Further consolidation took place in 2004 when Trac-x and iBoxx combined to form the CDX in North America, and the iTraxx in Europe and Asia. Since November 2007, Markit (www.markit.com), which had earlier been the administrator for CDX and the calculation agent for iTraxx, owns both families of credit indices. Markit owns the iTraxx, CDX, LevX and LCDX indices for derivatives and iBoxx indices for cash bonds.
The role of Delphi’s bankruptcy in the evolution of new protocols
As CDS markets evolved, CDS indices were fast becoming the centre of trading activity. Simultaneously, the notional value of contracts written on insurers who found a place in these indices also increased rapidly. At times the notional value of CDS contracts began to exceed the bonds outstanding. This trend was more pronounced when CDS contracts were written on issuers who found a place in the major CDS indices. The result was a scramble by protection buyers to find CTD bonds when credit events happened.
When Delphi, a major supplier of auto parts to General Motors, filed for bankruptcy (Chapter 11 in the United States) in October 2005, it was reported to have $28 billion notional value of CDS contracts against $5.2 billion in outstanding bonds. The rush to find bonds to deliver to the CDS contracts led to a rise in the bond prices after the bankruptcy filing. This was followed by a steep fall in the bond prices.
The Delphi episode was one of the primary triggers for the ISDA, the trade organization for derivatives, to step in and set up protocols for settling derivative trades, as also determining, through auctions, the value of the obligations of the defaulted reference asset. The option to settle CDS contracts in cash (as opposed to physical settlement that led to complications as described) was popularized around this time.
The auctions happen in two stages. In the first stage, about 15 dealers submit bid and offer prices for the bonds of the reference asset, with a bid-offer spread of maximum 2 points. In the second stage, these bids and offers are bifurcated. Where the bids are higher than offers by other bidders, they are excluded from the calculation as ‘tradeable’. The objective of this process is to prevent manipulation or misuse of the auction mechanism. The remaining bids are again bifurcated, and the best half of the two is selected. The average of the bids and offers in this best half is the auction settlement price or the ‘inside market midpoint’. This process establishes the price of the instruments.
Market Participants
Apart from Markit, which owns and operates the indices, the other participants include all major banks dealing in derivatives, institutional investors, ISDA (responsible for globally approved legal documentation) and other parties who use and trade in the indices.
Trading Practices
Markit categorizes its tradable credit indices into three broad categories
The indices under ‘structured finance’ are the ABS, CMBX and the TABX, traded exclusively in the United States. ‘Synthetic fixed income’ indices form the largest category with the following sub-categories
FIGURE 9.15 CATEGORIES OF SYNTHETIC FIXED INCOME INDICES
Each index has its unique features and notations. Indices roll every 6 months, and a new series is created with updated names. However, the previous series will continue trading.
The CDX indices, e.g., are broken out between investment grade (IG), high yield (HY), high volatility (HVOC), crossover (XO) and emerging market (EM). The CDX.NA.HY is the notation to indicate an index based on a basket of North American (NA) single-name HY CDSs. The XO index includes names that are split-rated, meaning they are rated IG by one agency, and ‘below IG by another. The CDX index rolls over every 6 months. There are 125 names in the IG index, with maturities of 1, 2, 3, 5, 7 and 10 years, and 100 names in the HY index, with a single maturity of 5 years. These names enter and leave the index as appropriate. For example, if one of the names is upgraded, it will move, say, from the HY index to the IG index when the rebalance occurs. The tranches for each index are standardized. For example, for the CDX, NA.IG, the tranches are 0–3, 3–7, 7–10, 10–15, 15–30 and 30–100. The significance of these tranches is as explained earlier using the hypothetical iTraxx example.
The LCDX basket is made up of 100 single-name, senior secured loans in the United States. Prices are quoted for maturities of 3 and 5 years, rolled over every 6 months.
The iTraxx Europe has 125 names, while the iTraxx Asia (Japan) has 50 names. Almost all the indices are rolled over every 6 months, but the maturities for which prices are quoted differ from index to index.
Payments from the protection buyer to the protection seller are made quarterly—the 20th of March, June, September and December—except in the case of CDX.EM, where payments are semi-annual. The payments accrue on an Actual/360 basis.
The ‘cash-fixed income’ category comprises of bonds. The index is iBoxx and is traded in Europe, Asia, United States and the emerging markets (EM).
More on trading rules can be found on Markit’s Web site, www.markit.com. (May 2009)
The Credit Event Fixings have been developed by Creditex and Markit along with ISDA and major dealers in credit derivatives. The objective of credit fixings is to ensure a fair, efficient and transparent process for settlement of credit derivative trades following a corporate default. They are an integral part of ISDA’s CDS Index protocols. Creditex and Markit have jointly acted as administrators of the Credit Event Fixings since their inception in June 2005.
Tradable credit fixings are determined based on a well-defined methodology for iTraxx Europe—iTraxx 5 year Europe, HiVol and XO indices. A North American version is shortly expected to be in the market. Credit fixings take place weekly on Fridays. More details can be accessed at www.creditfixings.com.
During a Credit Event Fixing, dealers place executable orders on the Creditex platform for the reference asset of a particular company in respect of which a credit event, such as filing for bankruptcy, has occurred. A market standard methodology is used to simultaneously execute these orders and generate a final cash settlement price for eligible credit derivative contracts in respect of this reference asset. Markit verifies the integrity of the process and calculates the final price which it publishes on the Credit Fixings Web site.
When some of the world’s largest banks folded up quietly overnight in 2007–2008, afflicted by the ‘subprime crisis’, shaking up powerful economies, leaving stock markets and investors in a state of panic, taking centre stage in the crisis were the ‘villains’—structured products and the credit derivative.
The subprime crisis that began in mid 2007 is widely regarded as the first financial crisis in the age of mass securitization. It has unleashed a flurry of daunting questions on the very foundations of securitized finance and structured products. Just about everything related to the credit market is being questioned—is it right to originate and distribute? Is Basel II (to be discussed in a later chapter) adequate to control credit risks and ensure adequacy of bank capital? With its reliance on internal models and external credit rating agencies, can the credit risk be wished away by merely dispensing with complex derivatives? Is ‘financial engineering’ a dirty word?—and the debate goes on.
Funds and banks around the world purchased bonds or the risk related to bonds, backed by home loans, often bundled into CDOs. These CDOs were backed by pools of mortgages or other income-producing assets and considered essentially ‘bond like’ in that they offered investors a steady stream of returns. Investors found these securities attractive as they offered higher returns at a time when traditional fixed income or debt-related products were yielding lower returns. Investors also viewed these structured products to be quite ‘risk free’, when they were certified to be so by the top rating agencies of the world. The ability of ‘structured finance’ to repackage risks and create ‘safe’, tradable assets from risky, illiquid collateral was the reason for the meteoric increase in the issue of structured securities.
However, as low interest rates in many parts of the world fuelled a lending boom to less than creditworthy borrowers, banks looked for new avenues to package and sell these loans, so that they could get liquidity to lend more. By selling off risky loans, banks could maintain less regulatory capital commensurate with the risk. Hence banks and other financial institutions pooled these asset-backed securities into new pools, dividing them up and issuing securities against them, thus creating CDOs. The concept caught on pretty fast, with new combinations that were further and further removed from the original underlying asset. Such innovations included CDOs of CDOs or CDO-squared and even CDO-cubed.
According to J. P. Morgan, there are about $1.5 trillion in CDO, referring to those made up of bonds backed by subprime mortgages, slightly safer mortgages and commercial mortgage-backed securities.
Then what went wrong?
At the core of the crisis has been the housing boom in the United States since the beginning of the decade. Low interest rates meant home buyers could take larger loans, giving rise to a housing bubble marked by unrealistic optimism and a failure to consider the downside, since it was assumed that all foreseeable downside was taken care of while designing the securitized products. The cracks began showing in 2006, when subprime borrowers increasingly defaulted on monthly payments due to annual interest rate resets on their floating rate loans. Fears of recession caused bloated housing prices to dip alarmingly, and in 2007, prices of securities based on subprime loans were in free fall as investors feared that they would not get the promised payments from the structured securities. Lenders became wary and showed reluctance to lend.
With the underlying assets—the subprime mortgages—fast losing value, dangerous levels of leverage were revealed in the packaged securities, leading to the discovery that the ‘safe’ CDOs and other securities were actually far riskier than originally envisaged. As the complexity of these products increased, so did their opaqueness. The extent of losses that they have generated has surprised not only investors, but also the funds and bankers themselves. This was when weaknesses in the system were laid bare, including ratings that did not accurately reflect risk and faulty assumptions on how diversified pools would act on multiple layers of leverage.
The innovation in structured products was assisted by the rise of credit derivatives—especially CDSs. CDSs became staggeringly popular over the last few years throughout the developed world. CDSs resemble an insurance policy to the extent that they can be used by debt owners to hedge, or insure against a default on a debt. However, because there is no requirement to actually hold any asset or suffer a loss, CDSs could also be used for speculative purposes.
Thus, credit derivatives allowed banks to hedge their exposure to the subprime loans they had made, and also freed up capital—since they did not have to reserve capital for potential losses. The banks partnered with hedge funds—lightly regulated pools of capital with high fees—looking for better returns. Insurance companies and pension funds also sought the higher yields as interest rates hit historically low rates.
Annexure I presents a case study in the form of a brief chronology of events leading to the crisis that hit the United States and Europe.
Are structured products and credit derivatives really the villains of the high drama in the financial world? Who is responsible for the mammoth fiasco—Basel II, the rating agencies, the regulators or the banks themselves?
One possible inference is that the benefits of financial structuring and risk management are small compared to the huge costs they impose on financial stability and the reputation of banks. An alternative, therefore, is to return to ‘good, old-fashioned banking’ where banks create loans and hold them on their balance sheets and do not synthetically pool, package and distribute them.
Another argument advanced against credit risk transfer mechanisms is that they create the problem of ‘moral hazard’. The originators of loans do not assess the credit quality with the same rigor that they would exercise were they to hold them on their balance sheets. This allegation seems to be true in the light of the findings of the 2008 and earlier surveys of credit underwriting practices in the United States.104 The findings show that credit appraisal and delivery standards had in fact declined over the previous periods and banks have begun exercising more prudence in granting credit post the credit crisis. Table 9.14 summarizes the changes.
TABLE 9.14 TRENDS IN CREDIT APPRAISAL AND DELIVERY STANDARDS
Basel II has also been squarely blamed for the incentive for banks to take risky assets off their balance sheet, or simply transfer the risk to willing sellers of protection—to comply with capital requirements. Theoretically, originators of loans can assume that assets or risks are off their balance sheet when they distribute them. Hence, the need to maintain capital on these assets is obviated. But for reputation, the originators may feel compelled to repurchase securities sold earlier. Then the assets come right back on the balance sheet—and when this would happen cannot be determined. For instance, Citigroup was seen to act responsibly when it included put options on CDOs backed by subprime mortgages that it sold to customers. The ‘puts’ gave the buyers the right to sell the securities back to the originator in case of financing problems. This contingency was not accounted for in the bank’s balance sheet.
Sophisticated financial models of asset portfolios have been built and used by the banking system and these have now come under the scanner. Were the financial models flawed or was there too much reliance on the results that they threw up? For example, Northern Rock, one of the biggest casualties of the UK, had reportedly carried out extensive stress testing as stipulated by the UK Financial Services Authority only in the first half of 2007 and the results sounded no alarm. Evidently, the probability that all the bank’s funding sources could dry up simultaneously was not one of the scenarios tested—since this looked highly improbable at that time!
The leading rating agencies of the world—S&P, Moody’s, Fitch—have all drawn huge flak for their ‘failure’ to distinguish the riskiness of different securities. They have been accused of being too generous with their AAA ratings, and worse still, overlooking the potential downfall of the market as the underlying mortgage assets deteriorated in value. The worst cut of all—they reacted with wholesale downgrades when the market collapsed. The possible conflicts of interest arising from rating agencies being paid by the issuers and the same agencies offering advisory services to the issuers are also areas drawing criticism.
And there could be other reasons too—Was it the structured investment vehicles (SIVs, similar to special purpose vehicles/entities (SPVs) or (SPEs) and other mechanisms that used short-term bank funding to invest in long-term derivatives, or was it their opaqueness, or was it the lack of proper regulation?
The Way Forward There are two alternatives before banks.
They return to ‘good, old-fashioned banking’, where banks originate and hold the assets till they are liquidated. But this option ignores economic realities. Deregulation has already come to stay, and structured products and risk management are inexorably linked with the broader deregulation of the financial markets and financial technology, backed by the dramatic leap forward of information technology and communication. Even if we turn the clock back and launch the era of strict and restrictive regulation, the advances made in communication and technology would make it possible for banks to move risks and assets offshore, and securitization would take a different form.
The second alternative is to recognize the real benefits of securitization and financial innovation—after all, these innovations have shown us methods of packaging and redistributing risk, transforming illiquid assets on bank balance sheets to tradable ones with attractive income streams; they have shown banks how to reduce holding costly capital to absorb the credit risk; they have given liquidity to the system and lowered funding costs.
Innovation has its costs too—as the present crisis has shown. But this is a necessary though unwelcome cost of learning. Pioneering efforts in any industry have always run into rough weather for lack of prior experience. The global turbulence is a heavy price to pay for innovation, but central banks and governments have acted swiftly to soften the blow to the banking system and markets.
The present crisis can therefore be considered a maturity crisis of the credit market after the development of credit derivatives. At first glance, it looks like a massive failure of most used quantitative models of credit derivative pricing. However, we would have to remember here that there is a basic risk involved in lending money, and that this risk comes at a price, and credit derivatives have found a way to merely transfer this risk, but not to wish risk away! Probably, armed with a deeper understanding of the causality of the credit default process, deductive models with better and better predictive ability can take care of the changing environment.
The signals are now quite clear. The OCC Survey sums it up neatly. ‘While the competitive environment will inevitably cause changes in credit underwriting standards, banks need to have risk management and control processes to signal when standards veer away from safe and sound banking practices. Banks should underwrite credit based upon an expectation that the borrower can repay the loan, regardless of whether the loan is intended for portfolio or for distribution. As recent events have clearly shown, liquidity conditions in credit markets can change abruptly. Banks originating credit for distribution should maintain underwriting standards reasonably consistent with the standards for their own portfolio holdings.’106
In a bid to ensure the stability of the financial system, several regulatory and market-related changes are being introduced. One of the focus areas of these changes is credit derivatives. Even though public interest has turned towards the credit derivatives market only recently, the derivatives market has been focused on by regulators over the years. Regulatory attention is now most pronounced in the United States and Europe, where the crisis has taken its severest toll.107
A major lesson of the crisis seemed to be insufficient regulatory oversight over CDS and other structured instruments. In its final report, the US Financial Crisis Inquiry Commission (FCIC 2011, p 50) noted that “key OTC derivative in the financial crisis was the Credit Default Swap”.
Some of the important international regulatory developments in the CDS markets are given below:
Deemed as one of the greatest regulatory overhauls of financial markets after the Glass Steagall Act almost eight decades earlier, the Dodd Frank Act contains at least three regulatory aspects that directly impact the CDS market. One, the Volcker Rule, which separates proprietary trading from commercial banking activities; two, the central clearing of CDS indices, and three, the gradual phasing out of uncleared single name CDS.
In October 2011, the European Commission adopted a legislative proposal for the revision of Markets in Financial Instruments Directive (MiFID) which took the form of a revised Directive and a new Regulation. After more than two years of vigorous debate, the Directive on Markets in Financial Instruments repealing the earlier Directive in 2004 and the Regulation on Markets in Financial Instruments, commonly referred to as MiFID II and MiFIR, were adopted by the European Parliament on 15 April 2014, by the Council of the European Union on 13 May 2014 and published in the EU Official Journal on 12 June 2014.
Building on the rules already in place, these new rules are designed to take into account developments in the trading environment since the implementation of MiFID in 2007 and, in light of the financial crisis, to improve the functioning of financial markets making them more efficient, resilient and transparent.
The Basel regulations, which is being discussed in detail in Chapter 11, prescribe international standards for bank capital and associated risks, with a view to lending more stability to the global financial system.110
Basel 3 is currently being implemented, but there has been an almost constant review of various standards, which is being labelled widely as Basel 4. Currently, revisions are in place for market risk and counterparty risk, as well as securitization exposures. A notion of ‘liquidity horizons’ has been introduced. Valuation of illiquid positions such as CDS and Mortgage backed securities are also expected to be impacted.
The treatment of counterparty credit risk (CCP), the risk associated with derivatives has already been subject to substantial change under Basel 3 after the financial crisis.
A new credit valuation adjustment (CVA) volatility charge is being introduced by Basel 3. There are basically two ways to incorporate credit risk in valuing a derivative portfolio. One way is to discount expected cash flows of the financial asset, say a CDS, at a discount rate incorporating a credit risk adjustment. The other way is to apply a CVA. The CVA is the expected value or price of counterparty risk. The asset is valued at a risk free price (no credit risk) and a specific adjustment is made for counterparty risk. Basel 3 has introduced more stringent requirement for Internal Models Methodology (IMM) for determining capital requirements.
Ironically, about two years after the Dodd Frank act was passed, the large trading loss sustained by J P Morgan in early 2012 once again focussed on CDS. Dubbed as the London Whale case, this event once again served to highlight ineffective risk management in CDS trading strategies. The call for more stringent CDS regulations grew louder.
In the second half of 2015, the CDS market faced another tough challenge. A $1.86 billion settlement in favour of the Los Angeles Country Employees Association was made. The defendants in the case included 12 major Wall Street banks, the CDS industry representative ISDA (International Swaps and Derivatives Association) and the CDS data provider Markit Group Ltd. The defendants were accused of obstructing efforts in making the transactions more transparent.
Deutsche bank, a major participant in the CDS market, closed their books for single name corporate CDS in October 2014. In May 2015, the world’s largest asset manager, Black Rock, called for a market wide effort to revive the single name CDS market.
Central clearing, an important requirement of Dodd-Frank, will have to cover most CDS. From February 2014, The CDS Index trades have to be traded on Swap Execution Facilities and centrally cleared. However, single name CDS are not part of the central clearing system, which could distort the CDS index market.
However, the BIS quarterly review of June 2017111 notes that the share of outstanding CDS cleared through central counterparties (CCP) “jumped from 37% of notional amounts outstanding at end- June 2016 to 44% at end-December 2016. This movement represented the largest semiannual increase in the centrally cleared share since CCP data for CDS were first collected in 2010. The proportion of outstanding CDS contracts centrally cleared increased for single-name as well as multi-name instruments, although the proportion remained much higher for the latter: 54% compared with 36%. Multi-name products tend to be more standardised than singlename products and consequently more amenable to central clearing. Notably, the increase in the proportion was driven by a sharp decline in the uncleared segment of CDS markets. Whereas the notional amount cleared through CCPs was more or less unchanged in the second half of 2016, at $4.3 trillion, the notional amount for contracts between reporting dealers fell from $5.1 trillion to $3.7 trillion.”
However, it is noteworthy that the CDS market (outstanding notional size) had grown from less than $1 trillion in 2001, to over $60 trillion by 2007, when the financial crisis happened. The CDS market is currently at a fraction of its pre crisis levels.
‘Analytics will define the difference between the losers and winners going forward,’—Tim McGuire, a McKinsey director.
By this time, you would have understood that behind effective risk management, and a successful model that aids risk management, lies a very important ingredient – Information. Valuable information, in turn, is embedded in data that is grouped and analyzed to yield information for decision making and management. Banks and firms now realize that data and its proper analysis can be used effectively to increase productivity, improve decision making, enhance risk management capabilities and thus gain competitive advantage. Experts call it the ‘big data’ revolution.
In the world of finance, we know that ‘information’ has value. However, voluminous and unstructured data or information that most banks and firms seem to have today cannot be managed or analyzed by traditional tools. For example, banks traditionally gather data for reporting purposes—to their head offices, to central banks, to the government, to the public and so on. However, today data signifies not only the traditional data, but also enormous amounts of data that converge from click stream sources from the web, social media, and videos. Banks’ back offices generate voice data. Data is generated through the ‘cloud’. (It is estimated that Google alone processes over 24000 terrabytes per day!). However, these unconventional information sources are not tabulated in typical rows and columns that one can read or interpret.
Banks, in particular, have access to enormous information—customer data, transaction details, performance data, credit information, and so on—from both internal and external sources.
So the first question is—what is the data that they want to use and for achieving what purpose? With the help of advanced technology, it is now easy to gather data and store it. But the challenge is to determine which data to use, the best source for the data, and how to put it together into an integrated form that can serve the objective across the bank.
Therefore, a key capability to utilize the information explosion for data analytics is to identify, integrate and manage diverse sources of data. Another key capability is to build or use the vast data in advanced analytics models that would realistically predict future trends and outcomes. Of course, the most important requirement is the capability of management to integrate the data analytics models into the firm’s functioning so that better decisions can be made. The latter capability presupposes the existence of a clear strategy for transforming the way the firm works through data analytics, and the use of the most appropriate technology infrastructure and human skills. All this implies that the approach to using analytics for optimal decision making should be integrated with the sourcing of the correct and appropriate data. Information is costly, and lack of vision in collecting data and wondering how to use the data would lead to loss of productivity and undermine the firm’s competitive ability.
Banks need data analytics in a big way for managing risks—be it credit risk, market risk, operational risks, liquidity risk, or the interplay of various risks on the financial system. While regulatory prescriptions for risk management are driving banks to ‘big data’ analytics, banks are using the data generated for internal management as well.
Banks can benefit from ‘big data’ in a big way. The following diagram illustrates.
One of the very foundations of the ‘learning by doing’ concept of business games is the acceptance of failures, and the ability of deriving valuable learning from them. This very basic principle is what made Silicon Valley become the unique and striving start-up hub it is today, and it is most valuable skill for students to get a complete hands on before embarking on their journey as working adults. Business management simulations are the safer ways of helping the students first learn how to navigate the landscape of a real company, than losing out all their savings on a badly executed business idea or venture.
One of the key differentiators of business simulation games is that it acts as an excellent tool to practice real world business decision-making skills as everything happens in a risk free simulated learning environment. This encourages the students to try out different strategies, observe the results, monitor market fluctuations, then pivot their direction, all without real-life repercussions.
With the massive surge of multiplayer online games, most college students today prefer an environment where they could interact with other players in either a cooperative or competitive fashion. Business Games brings people together in virtual worlds, mirroring the phenomenon of increased internationalization and cross-border cooperation between businesses as well, a need of the hour.
In business simulation games students form the management teams of a virtual company that competes against other companies in the same market for a slice of the consumer pie. Today business simulation games with a fully web-based platform supported by an in-game messaging system, enables these teams from anywhere in the world to improve cross-campus cooperation and create exciting competitions between partner universities.
Another major appeal of many games would be their real time feedback on decisions made. This feature just not only makes participants more engaging, but also helps them practice a number of different strategies in a short period of time and discover what works best or better.
Most Business Simulation Games employ a round-based system which gives the students an opportunity to strategize with their teammates before coming to any final decisions, and also enabling the instructors/facilitators to schedule and manage his/her course better. The dynamic aspect is prevalent however in the decision-making areas, where students can immediately see the effect of their choices once they start experimenting with the decisions.
Good stories always captivates human brains, in business as well as in games, story driven game plays are very successful in enticing large audiences.
In higher education stories have been encapsulated in case studies, which although take students through a particular segment of a company’s life, it happens in a non-interactive format. Business Simulations on the contrary enables the students to further immerse by actually becoming the protagonists of their company’s story, and determining its faith through decisions made in a volatile environment. This not only does give students a greater sense of purpose, but also make them think much more carefully about their actions when they don’t only exist in theory.
What would this entire experience be without any satisfying rewards? Just like in any traditional games, business simulations also do reward players in one or more ways, most notably would be the rankings on the leader board, and/or by a market leadership position with a great cumulative total on business profits, shareholder returns, etc.
But the most valuable rewards for students is ultimately help them improve on their business decision making skills, holistic thinking, teamwork, proactive pivoting, and problem solving skills, all of which will be retained substantially longer than by others, less active forms of learning.
Credit risk models are valuable since they provide users and decision makers with insights that are not otherwise available or can be gathered only at a prohibitive cost.
