The CDS market did not exist 10 years ago. Today, the market for these securities is enormous. Since 2000, it has ballooned from $900 billion to more than $45.5 trillion — roughly twice the size of the entire United States stock market according to the New York Times. Although we’ve always been very vocal on the inherent risks of having an unregulated insurance market of this size (see the article), it must be said at the outset that, aside from a handful of hiccups, it has served its users well. Buyers of protection in the CDS market have always been paid in a market which has offered ample levels of liquidity. With the credit crunch came wider spreads on most CDS contracts, but they still settled. Market participants are honest and committed and there’s no reason to think they won’t be disciplined.
On the other hand, tthese instruments are designed to go through normal credit events and haven’t been properly tested in recessions. A bit like the subprime market, the market for default insurance is a product of good economic times.
As long as credit events are idiosyncratic, it is highly likely the CDS market will serve its purpose and buyers of protection will be reimbursed in an orderly fashion. Unfortunately, the current credit crunch and its subsequent impact on the real economy will have the effect of concentrating losses. At this point, the CDS market may be faced with a systemic shock it was never designed to handle. It’s a bit like a boat navigating through a channel with floating mines. If the mines are spread out, the odds of making it through are high. Unfortunately, if they start concentrating in several points, the risks of a “blow up” become greater.
Delivery of the underlying bonds and the example of Delphi
As we’ve just stated a default swap is a very useful tool to hedge credit risk but like virtually all derivatives, it also makes it very easy to take highly leveraged positions, long or short, in a given name. The difference between the CDS market and say the futures market is that it is an OTC market and there is no central depository or record of outstanding positions. There is also no natural limit on positions, as there is in the cash market. Shorting a cash bond stops when you can no longer borrow it. This barrier does not exist in the CDS world. We have seen many instances when a bond rallies significantly after default as the amount of protection written is a multiple of the outstanding issue (the reference security needs to be delivered to the seller of protection).Index CDS can be settled for cash but the ISDA agreements for single name CDS reference the bonds that must be delivered in the event of default.
With Delphi's bankruptcy in late 2004 and the subsequent auction/credit fixing, the credit derivatives market took a positive step forward in its rapid evolution. For DPH, initial estimates suggested that nearly USD$25Bln in gross credit protection had been written on some $2.2Bln bonds which could have led to a major bond squeeze and the absurd situation whereby a bankrupt companies’ bonds could have traded at par on short covering by dealers. The November 4 2004 auction proceeded without a major squeeze with most market participants easily settling without incurring basis gains or losses. Delphi bonds were trading in the low 60s at the time of the auction but traded as high as 70/71 before settling in the low 50s. There was a 20pt distortion because of the credit derivatives market and although not market disrupting, it was still a 30% move and certainly not insignificant. The NY Fed, which acts as the gatekeeper of the ISDA, urged dealers to get together to create a protocol for delivery which was hugely helpful.
Valuations of insurance coverage is more art than science
In the end, market participants worked out an auction system where settlements of Delphi contracts could be made even if the bonds could not be physically delivered.
This arrangement was done at just over 36 cents on the dollar; so buyers of protection on Delphi who did not have the bonds received $366.25 for every $1,000 in coverage they had bought. Had they been valuing their Delphi insurance coverage at $1,000 per bond, they would have had to write off that position by $633.75 per $1,000 bond.
That is why the valuation of these contracts is of such concern to some participants. As with other securities that trade privately and by appointment, assigning values to credit default swaps is highly subjective. So some on Wall Street wonder how much of the paper gains generated in these instruments by firms and hedge funds last year will turn out to be illusory when they try to cash them in.
Due to the CDS market, the rise in defaults may create a systemic shock: the GM downgrade
The theme had been that derivatives are an instrument that helps diversify risk and stabilize risk-taking. This is very questionable and some feel that if Delphi’s default had been related to a much bigger company like GM it could have been a different story. Even though DPH’s default involved a constituent of one of the investment grade indices and S&P noted DPH appeared in over 800 synthetic CDOs (representing about 35% of its universe), the variety of product in the bespoke market is much higher for GM. Regardless, the issue does not surround individual credit. It has more to do with the overall levels of leverage in the system. In the 90s, CDO equity tranches were 10% (10X leverage). Today, based on synthetic CDOs, the equity tranche is 3% (30X leverage). Buyers of the equity tranches are (or should I say were) all structured credit hedge funds which are already leveraged buying CDO^2 which are theoretically leveraged 900X. It’s quite apparent what the subprime market has done to most CDOs. Once defaults rise and CDS unwinds lead to increased volatility in the underlying and a sustained rise in credit spreads, we just don’t know how the CDO and CLO markets will behave. Incidentally, 16 percent of the CDS market is designed to protect holders of collateralized debt obligations according to a recent CNBC survey.
Who’s on the other side and how can they repay?
Another issue relates to the fact that traders don't have a clear idea about who ultimately is on the other side of derivative trades that aren't executed on regulated exchanges. As we have stated, these agreements are completely uncollateralized with hedge funds acting as one of the many participants who have written insurance. It’s a worry, as their assets can very easily walk out the door on the back of investor redemptions, leaving them penniless. This is scenario is very likely to occur sooner rather than later. Hedge funds have aggressively written CDS contracts to boost returns. As the markets take a turn for the worse, their returns suffer, leading to many investor redemptions (we’ve seen it all too often last year). At the same time, default rates are rising and some of the names the hedge fund wrote protection on go belly up. The banks that act as counterparties in these transactions won’t be able to get their money back as the hedge fund’s tills are completely empty (credit default swaps were invented by major banks in the mid-1990s as a way to offset risk in their lending or bond portfolios). They will therefore have to write down tens of billions in losses and may very well become insolvent (or seen as a risky counterparty at the very list raising its own cost of financing). There could easily be more pain ahead.
During the credit market upheaval in August 2007, 14 percent of trades in these contracts were unconfirmed; meaning one of the parties in the resale transaction was unidentified in trade documents and remained unknown 30 days later. In December, that number stood at 13 percent. Because these trades are unregulated, there is no requirement that all parties to a contract be told when it is sold. As investors who have purchased such swaps try to cash them in, they may have trouble tracking down who is supposed to pay their claims.
The intricacies of the CDS product offered mixed results in 2007
Hedge funds investing in bank loans had quite some difficulty using CDS insurance to protect their long market exposure last year. The CDS market moved in very erratic fashion compared to the underlying adding what is called in hedge fund jargon, basis risk. A positive basis trade is when the yield on the bond is higher than on the CDS covering the exact same bond of the same duration and ultimately offers hedge funds positive carry. Unfortunately this basis can become negative when CDS and underlying become disjointed (as we have seen too often last summer and again in January of this year).
Furthermore, even though CDS aren’t affected by the same “greeks” as their equity derivative counterparts (they are swaps after all), there are still a multitude of dimensions investors need to be aware of. There exists, for instance, a relationship between equity volatility and spreads which ultimately will affect the value of the CDS. Buying CDS protection for instance, whilst holding the underlying bond will more often than not create a position that, in the event of a sharp rally in the stock, is short gamma on the credit. The intricacies of these relationships require very high levels of education which is more often than not lacking.
The Office of the Comptroller of the Currency, a US federal banking regulator, warned that a significant increase in trading in swaps during the third quarter of last year “put a strain on processing systems” used by banks to handle these trades and make sure they match up. The good news is that a major catastrophe was averted; the bad news is that painless lessons are all too quickly forgotten.
