A debt instrument is a financial instrument that represents money that is owed from one party to another. It is typically used as a form of financing for businesses and individuals. Examples of debt instruments include bonds, loans, mortgages, and promissory notes. These instruments are typically issued by governments, corporations, or other entities in order to raise funds for their operations. The terms of the debt instrument, such as the interest rate, repayment schedule, and maturity date, are usually specified in the contract. Debt instruments can also be traded on the secondary market, allowing investors to buy and sell them.
