Bullet maturity refers to a specific type of bond or debt instrument that has a single maturity date. With a bullet maturity structure, the issuer of the bond or debt makes periodic interest payments to the bondholders over the life of the bond. However, the principal amount is repaid in full on the maturity date, rather than being paid in installments over time. This contrasts with amortizing structures where the principal is paid down gradually. The bullet maturity feature provides simplicity and clarity in terms of repayment, as the entire principal amount is due at a specific future date.
