Reading 32: Credit Default Swaps Flashcards
Credit Default Swap
- essentially and insurance contract
- if a credit event occurs, the credit protection buyer gets compensated by the credit protection seller.
- protection buyer pays seller a premium called the CDS SPREAD
- Protection seller is assuming (long) credit risk, while the buyer is short credit risk.
- delivered in cash or physical delivery
Notion Principal
-Face value of protection
Components of CDS
- Protection buyer: short credit risk or reference asset and short the CDS
- Protection seller: long the CDS and long the credit risk of reference asset
Coupon Rates
-standardization has led to fixed coupon rates (1% for IG, 5% for HY)
EX:
CDS on IG bond with credit spread of 75bps would require a coupon payment of 1% by the protection buyer. This would lead to buyer paying too much. Seller would pay upfront to the buyer the PV of 25bps present value of notional principal.
International Swaps and Derivatives Association
-unofficial governing boy of the industry, publishes standardized contract terms and conventions in the ISDA Master Agreement to facilitate smooth functioning of the CDS market.
Single name CDS
- reference obligation is the fixed income security on which the swap is written, usually a senior unsecured obligation.
- The issuer is the reference entity
- When does it pay out: only when reference entity defaults on the reference obligation or when they default on any other issue that is ranked pari passu.
- Payout is based on market value cheapest-to-deliver method
EX
$10M notional principal, bond trading at 25% of par. Payout:
$10M - (0.25)($10M) = $7.5M
Cheapest-to-deliver
-debt instrument with the same seniority as the reference obligation but that can be purchased and delivered at the lowest cost.
Index CDS
- covers multiple issuers, allowing market participants to take on an exposure to credit risk of several companies simultaneously in the same way stock indexes allow investors to take on an equity exposure to several companies at once.
- Protection for each issuer is equally weighted
Ex:
Party X is buyer in five-year, $100M notional principal CDS for CDX-IG, which contains 125 entities. One index constituents defaults and bond trades at 30% of par after default.
CDS payoff? $100M/125 = $0.8 per entity. Payout is $0.8Million - (0.3)($0.8M) = $560,000
Notional P after default? $99.2M
Default Types
- bankruptcy
- failure to pay
- restructuring
*Determination Committee declares when an event occurs.
CDS Settlement
-Physical
Swap seller gets reference obligation
Swap buyer gets par value
-Cash
Swap buyer gets payout amount = (payout ratio x notional principal) or (Par Value - Market Value)
Factors affecting CDS Pricing
-probability of default (or hazard rate)
PODt = PS(t-1) * hazard rate
-loss given default
-coupon rate on swap
CDS premium
CDS Spread = (1 - RR) * POD
Upfront payment (by protection buyer)
PV(protection leg) - PV(premium leg)
can approximate as:
CDS spread - CDS coupon rate
Upfront premium %
(CDS spread - CDS coupon) x duration = upfront premium%
CDS spread = (upfront premium %/duration) + CDS coupon
Price of CDS
$100 - upfront premium (%)
