A negotiable certificate of deposit is a large-denomination bank deposit that can be sold to other investors in a secondary market before it reaches maturity. Unlike a standard certificate of deposit, which locks your money in place until the term ends, a negotiable certificate of deposit gives you an exit option. You cannot redeem it early from the issuing bank, but you can sell it to someone else and walk away with the market price.
Citibank invented the instrument in 1961, creating a secondary market in negotiable certificates of deposit to help banks raise large amounts of short-term funds at a time when institutions were shifting money into bonds and other liquid assets.
A negotiable certificate of deposit requires a minimum investment of $100,000, though most trade in denominations of $1 million or more. Maturities typically range from two weeks to one year, with an average maturity currently around two weeks in active trading markets.
Interest can be fixed for the full term or floating, pegged to a benchmark rate like the Secured Overnight Financing Rate. You receive interest at maturity for short-term instruments. If the term exceeds one year, interest is paid semiannually. The issuing bank has no call option on most negotiable certificates of deposit, so the terms you agree to at issuance hold for the full life of the instrument.
Negotiable certificates of deposit are institutional instruments. Corporations, insurance companies, mutual funds, pension funds, and money market funds use them to put large amounts of cash to work for short periods while preserving the option to access liquidity by selling in the secondary market.
They sit in the portfolio as a cash management tool. The yield is typically close to a Treasury bill rate, reflecting the near-equivalent short-term safety, while FDIC insurance covers the first $250,000 of the deposit. The primary risk above that threshold is the credit quality of the issuing bank.
Interest rate risk is the most common concern. If market rates rise after you buy, the market value of your fixed-rate negotiable certificate of deposit falls, because buyers in the secondary market can get better rates on new issuances. You will sell at a discount to the face value. Credit risk is low but real. If the issuing bank defaults, you face losses on anything above the FDIC limit. Callable versions, while less common, expose you to reinvestment risk if the bank exercises the call option during a low-rate environment.
