Debt markets, also known as bond markets, are platforms where investors buy and sell debt securities. These securities are essentially loans made by investors to borrowers, which can include governments, municipalities, and corporations. In return for lending money, investors receive interest payments and the return of their principal at maturity. The primary purpose of debt markets is to facilitate borrowing and lending. When a government issues bonds, for example, it raises funds to finance public projects. Similarly, corporations issue bonds to fund expansion or operations. Overall, debt markets play a crucial role in the global economy by providing liquidity and enabling capital flow.
