Interest rate swaps and currency swaps are contracts in which counterparties agree to exchange cash flows according to a pre-arranged formula over a period of time. Since 1985, the federal government has been using such swaps to manage its liabilities in a cost-effective and flexible manner.
The authors outline the characteristics of swap agreements and the ways in which the government uses them. They show that the swap program has been cost-effective, estimating that past and projected savings exceed $500 million. The authors also discuss the methods that the government uses to monitor the counterparty credit risk associated with these transactions.
