Definition: Certificate of deposit
External debt - IMF
A certificate issued by a bank acknowledging a deposit in that bank for a specified period of time at a specified rate of interest; CDs are essentially a form of negotiable time deposit (evidenced by the certificate). CDs are widely issued in the domestic and international markets, and are typically bearer instruments, issued at face value with original maturities of one to six months, although there have been maturities of up to seven years. Typically, interest costs are payable at maturity for issues of one year or less, and semiannually on longer issues. The rate of interest on a given CD depends on several factors: current market conditions, the denomination of the certificate, and the market standing of the bank offering it. Typically, CDs are highly liquid instruments, which allows banks access to a cheaper source of funds than borrowing on the interbank market.
