The maturity date is the specific date on which a financial obligation, such as a bond, loan, or other debt instrument, becomes due and payable in full. On the maturity date, the borrower is required to repay the principal amount of the debt, along with any remaining interest that has accrued. The maturity date is a key term in the contract governing the debt instrument and is agreed upon by both the lender and the borrower at the time the debt is issued.
