Credit Risk in Swaps
Credit Default Swaps
Despite the similarity in names, a credit default swap, or CDS, is not the same type of
instrument as interest rate or currency swaps. As we saw in Chapter 14, payment on a CDS
is tied to the financial status of one or more reference firms; the CDS therefore allows two
counterparties to take positions on the credit risk of those firms. When a particular “credit
event” is triggered, say, default on an outstanding bond or failure to pay interest, the seller
of protection is expected to cover the loss in the market value of the bond. For example,
the swap seller may be obligated to pay par value to take delivery of the defaulted bond (in
which case the swap is said to entail physical settlement) or may instead pay the swap buyer
the difference between the par value and market value of the bond (termed cash settlement).
The swap purchaser pays a periodic fee to the seller for this protection against credit events.
Unlike interest rate swaps, credit default swaps do not entail periodic netting of one
reference rate against another. They are in fact more like insurance policies written on par-
ticular credit events. Bondholders may buy these swaps to transfer their credit risk expo-
sure to the swap seller, effectively enhancing the credit quality of their portfolios. Unlike
insurance policies, however, the swap holder need not hold the bonds underlying the CDS
contract; therefore, credit default swaps can be used purely to speculate on changes in the
credit standing of the reference firms.

Economics 9 (1981).
Commodity futures prices are governed by the same general considerations as stock futures.
One difference, however, is that the cost of “carrying” commodities, especially those subject
to spoilage, is greater than the cost of carrying financial assets. The underlying asset for
some contracts, such as electricity futures, simply cannot be “carried” or held in portfolio.
Finally, spot prices for some commodities demonstrate marked seasonal patterns that can
affect futures pricing.
