"Big Bang" is just a pretentious term referring to the day of April 8, 2009. That day will see radical changes in some of the standard terms or conventions of CDS contracts. These changes are:
For all CDS globally:
- Hardwiring of Auction Protocol
- Formation of Event Determination Committees
- Changing of Effective Dates for Protection
For CDS in North America only:
- Setting of 100/500 bps Fixed Coupons
- Removing of Restructuring Clause
- Changing the Convention for Accrual to Full Coupon
These contract changes will involve new contracts immediately. It will also be possible to make the new changes effective for legacy contracts.
These changes are intended to make CDS contracts more liquid. There will be more standardization and more clarity regarding credit and succession events. These changes will make it easier to offset existing contracts.
The most significant one change involves the use of fixed coupons for all CDS contracts in North America. That is a very logical thing to do and is probably agreed by all market participants. In contrast, the removal of "Restructuring" as a credit event may be more questionable. This will reduce the impact or efficient of CDS contracts. It has an economic impact because less is the coverage of credit events, less is the value of bought protection. Restructuring is already not included as a credit event in credit indices. Making single name CDS to follow the same convention as these indices will help with their liquidity.

More important changes are those that involve the CDS contracts in North America:
• Setting of 100/500 bps Fixed Coupon: Any single name CDS will have a pre-set coupon of either 100 bps or 500 bps. Currently, a new trade for CDS on a single name is entered at the current market spread by convention. As a result, a new trade does not require cashflow exchange. Only when there is a considerable default risk, trading of CDS contracts shift to a set 500 bps coupon and the quotes involve the upfront amount required to be posted for trade. Generalizing this to all CDS means new trades will require cashflow exchanges. This is not much different than the trading of a bond for example. There is a fixed coupon, but the current effective spread is most usually different than that fixed coupon. The market quotes a yield or spread that is different than the origination yield or spread. Besides the benefit of added liquidity, this change will help with a typical CDS problem. A party that entered into a CDS contract can close it by either unwinding or by entering into another CDS contract at opposite direction at a different spread. This eliminates the jump to default risk but keeps in the books an interest-only type strip that still carries a risk exposure.
• Removing of Restructuring Clause: Restructuring will be dropped from the definition of credit events for standard contracts. Currently, the CDS contracts referencing the investment-grade credits trade with “Modified-Restructuring” being defined as a credit event. On the other hand, neither the credit indices nor those CDS contracts referencing high yield credits include that definition. Restructuring will drop out as a potential trigger/credit event for all North American CDS contracts.
• Changing to Full Coupon Convention for Accrual: This will involve just a convention change concerning the first premium calculations. Current conventions use either a short stub or long stub to calculate the accrual depending on the timing of trade entry during the quarter. The changes proposed will make the accrual calculations more in line with those for bonds.
As for the global contract changes, these incorporate the lessons of many credit events that occurred during this credit crisis:
• Hardwiring of Auction Protocol: Following a credit event, the dealers hold an auction to determine the recovery rates to be used in cash settlement of CDS. Those parties that agree to protocol before the auction will use the auction results to settle their CDS. Signing up to this auction protocol was optional. Those that wanted to sign up had to send in confirmations. This signup to accrual will be the default choice, rather than optional. Alternative is always to settle by physical delivery of the referenced debt. Those that want to opt out of auctions will have to state so beforehand.
• Formation of Event Determination Committees: It is not always clear cut whether and when a credit or succession event occurs. In the end, the market participants will have to interpret whether a corporate event fits into pre-defined legal language of the ISDA CDS contracts. To prevent potential disagreements, a committee of large market participants will make binding determinations on the existence and timing of credit or succession events.
• Changing of Effective Dates for Protection: This involves the CDS protection to be effective a little further in past, not simply the next day following the trade date. For credit events, the protection will be effective for 60 days before the current date. For succession dates, it would be 90 days prior.
Overall, these changes are a significant positive for credit markets. They should be considered one of the steps to eventually move CDS trading to exchanges.
