Term maturity Definition: That date at which the principal on a bond or similar financial asset needs to be repaid. Maturity dates can be anywhere from a few hours to 30 or more years. For example, government securities are classified by their maturity dates, with Treasury bills maturing in one year or less, Treasury notes in 1 to 10 years, and Treasury bonds in 10 years or more. Under normal (nonrecessionary) conditions, shorter maturity periods carry lower interest rates, while longer maturities need higher interest rates to compensate for the uncertainty of tying funds up for longer periods.
