Debt refers to an amount of money borrowed by an individual, corporation, or government from another party, usually with the agreement to repay it over time with interest. It can take various forms, including loans, bonds, and credit lines, and is a fundamental component of modern economies. Debt enables investment and growth but can also pose risks when repayment obligations become unsustainable. Investors monitor debt levels closely as they influence credit ratings, interest rates, and overall economic stability.
