U.S. Savings Bonds are government-backed securities designed to help individuals save money while earning interest. They are sold at a discount and can be redeemed for their full value after a set period, typically 20 years. There are two main types: Series I bonds, which protect against inflation, and Series EE bonds, which earn a fixed interest rate. These bonds are easy to purchase online through the TreasuryDirect website and can be bought in small denominations, making them accessible for many savers. They are considered a safe investment, as they are backed by the full faith and credit of the U.S. government.
