The unravelling of the housing market, followed by the credit markets, was, (in my opinion) due to the proliferation of <a href="http://en.wikipedia.org/wiki/Credit_default_swap">Credit Default Swaps a.k.a CDS's</a>. CDS's were invented by a brilliant British woman - <a href="http://mycrains.crainsnewyork.com/40under40/profiles/2004/228">Blythe Masters</a>. In the olden days, if you bought a bond, your risks were:
a. Default on the payment of interest.
b. Insolvency of the issuer.
c. Pre-payment of the loan [with interest].
So, when you ask the question - "How about separating the risks from the instrument [the bond], and forfeiting a part of the interest received by the bond, and paying that as an "insurance premium" to the bond insurer. Well, this has been going on for a while - especially in the municipal bond industry. So far, so good.
'http://mycrains.crainsnewyork.com/40under40/profiles/2004/228' Ms. Masters</a> took this to the next logical step. What if you could "bet" on whether a financial entity will default on their debt [or not]? This "bet" is what a CDS is...... a CDS is a contract between a buyer - who makes periodic payments to the seller. If the financial entity defaults on their bonds, or if the entity's financial health changes significantly, the buyer of the CDS gets paid the face value minus the market value of the financial entity's bond.
An example
You (Bond Guru Inc.) were long a Lehman Brothers' CDS, and were probably paying a healthy quarterly premium to the seller (Default Newbie Inc.) of the CDS. When Lehman filed for bankruptcy, this created a <a href="http://en.wikipedia.org/wiki/Credit_event">credit event</a>. When the <a href="http://www.bapcha.com/?p=182">Lehman bonds were finally auctioned off</a>, they settled for 8.625% - or 8.625cents per dollar. In this case, Bond Guru Inc. - who were long Lehman's CDS, was obliged to get ($1.000 - $0.08625) = $0.91375 per dollar (from Default Newbie Inc.). The converse is true too. If Lehman's financial health improved [instead of deteriorating], Bond Guru Inc. could stop paying the premiums, and Default Newbie Inc. keeps all the money that they had collected in premiums. Alternately, Bond Guru could buy a "cheaper" CDS - where the premiums are lower.
The settlement
Congratulations Bond Guru Inc.! You did great with the Lehman CDS's. But, Default Newbie Inc. allocated [set aside for default] a half a cent per dollar of bond value of the CDS that he sold to you [for which you dutifully paid your premiums]. So, BG Inc. will receive 0.005 + 0.08625 = 0.09125 cents per dollar. Plus, Default Newbie Inc. will be in bankruptcy [liquidation].
The CDS market
Is $55,000,000,000,000.00 strong. So, everyone wants a piece of it. The players are:
1. Ice Ice Baby. <a href="http://finance.yahoo.com/q?s=ice">The Intercontinental Exchange.</a> [With <a href="http://www.markit.com">Markit</a>].
2. <a href="http://finance.yahoo.com/q?s=cme">The Chicago Mercantile Exchange.</a> [With <a href="http://www.citadelgroup.com">The Citadel Group</a>].
3. <a href="http://finance.yahoo.com/q?s=NYX">The NYSE/Euronext</a> - which will also use <a href="http://www.markit.com">Markit</a>.
4. <a href="http://finance.yahoo.com/q?s=NDAQ">The NASDAQ/OMX</a> - through Liffe [which is actually a part of the Euronext].
5. <a href="http://finance.yahoo.com/q?s=NITE">Knight/Trimark Group</a>.
While The Knight/Trimark group has already launched their CDS platform NetDelta; the ICE has a formidable record of bringing scalable products on-line in record time. In fact, the ICE's dominance of the West Texas Crude Intermediate [WTI] blind-sided the CME, an CME's stranglehold on the energy market/energy futures. Both the CME and ICE will dominate the market, but the NYSE, Nasdaq and Knight/Trimark aren't exactly spring chicken. They know this business too, and know how to make money with the slimmest of margins.
Unresolved Issues
1. There are two possible models for a CDE exchange. Once is the OTC model - where the exchange provides a medium to transact the business. The second model is the one of a central counter-party [the ICE/CME model] - where in either party's default, the exchange makes the parties "whole".
2. Since the numbers involved here are huge, and as we have found from the collapse of the banking system; mere capital requirements are insufficient to guarantee a functioning CDS market - where all defaults can be cured.
3. The CDS market is not [yet] regulated. Hence, there is little if any in margin requirements. Even 1% in margin equates to 550 Billion dollars. Capital that CDS sellers [insurers] like Default Newbie Inc. above cannot afford to lock up in these times [or other].
4. Neither can a central counter-party unconditionally guarantee the proper execution and clearing and in the case of default/credit event - the "making whole" of the party that purchased and paid the premiums for the CDS.
In other words, as we saw recently [during the Lehman Credit Event] - the default of one huge entity can wipe out a half a trillion dollars of equity. In other words, none of the five companies mentioned above can cure [the default of] their trading clients in the event of a default similar in size to the Lehman debacle.
In Part-II of this article, I will discuss which of these five companies are a worthy investment, and why.
