Bonds are one of the oldest, most essential, and most widely used financial instruments in global capital markets. As a core component of the fixed income market, bonds play a crucial role in capital preservation, income generation, portfolio diversification, and economic stability.
From governments financing infrastructure to corporations funding expansion, bonds enable long-term borrowing while offering investors predictable cash flows and relatively lower risk compared to equities. This comprehensive guide explores bonds in depth, covering their structure, types, valuation, risks, yields, taxation, market dynamics, and strategic role in modern investment portfolios.
A bond is a fixed income instrument that represents a loan made by an investor to a borrower, typically a government, corporation, or financial institution. When an investor purchases a bond, they are effectively lending money to the issuer in exchange for periodic interest payments and the return of principal at maturity.
A bond is a contractual promise to repay borrowed money with interest over time.
Bonds are legally binding debt instruments and form the backbone of the global debt market.
When a bond is issued, investors purchase it at face value or market price. The issuer pays periodic interest (coupon payments) and returns the principal amount on maturity.
Bonds can be held until maturity or traded in the secondary bond market, where prices fluctuate based on interest rates, credit risk, and market demand.
Government bonds are issued by central or state governments and are considered the safest fixed income instruments.
In India, government bonds are issued by the Government of India and state governments, while globally they include US Treasuries, UK Gilts, and Japanese Government Bonds.
