over-the-counter (OTC) derivative
USA
A derivative product not traded on any organized, regulated exchange. OTC derivatives are customized, bilateral, privately negotiated contracts, which, as a result, can be illiquid as compared to standardized exchange-traded derivatives. No exchange operates between, and essentially guarantees, the performance of the parties to an OTC derivative as is the case with exchange-traded derivatives. Examples of OTC derivatives include most credit derivatives, including credit default swaps (CDS), interest rate swaps and currency swaps.
