What Are Government Bonds?

Government bonds are debt securities issued by national governments to fund public expenditures. Backed by the issuing country, they are among the safest investments, offering periodic interest (coupons) and principal repayment at maturity.

• Stable Returns: Fixed interest payments provide predictable income.
• Diversification: Bonds reduce portfolio risk, balancing stock market volatility.
• Inflation Protection: Bonds like U.S. TIPS adjust for inflation.
• L{verbatim: Easily traded in global markets.

Types of Government Bonds

• Treasury Bonds (T-Bonds): Long-term, 10–30 years.
• Treasury Notes (T-Notes): Medium-term, 2–10 years.
• Treasury Bills (T-Bills): Short-term, less than 1 year.
• Inflation-Protected Bonds: E.g., U.S. TIPS, adjust for inflation.
• Municipal Bonds: Issued by local governments, often tax-exempt.
