How US Savings Bonds Work
US savings bonds are government-backed securities sold directly through TreasuryDirect.gov. They cannot be bought and sold on secondary markets — they must be redeemed through the Treasury. Both EE and I bonds have a 1-year minimum holding period; redeeming within the first 5 years forfeits 3 months of interest.
EE vs I Bonds
EE bonds currently earn a fixed rate and are guaranteed to double in 20 years. I bonds adjust their rate every 6 months based on CPI-U inflation. In high-inflation years (2022: 9.62%), I bonds dramatically outperformed. In low-inflation years, EE bonds may be better. Many investors hold both types.
FAQ
How do Series EE bonds work?
Series EE bonds are purchased at face value and earn a fixed interest rate. The US Treasury guarantees they will double in value in 20 years (minimum), equivalent to a 3.5% annual return. After 20 years, they continue earning interest for up to 30 years total.
How do Series I bonds work?
Series I bonds earn a composite rate combining a fixed base rate plus an inflation adjustment (CPI-U) updated every 6 months. They protect against inflation but may earn 0% in low-inflation periods. The current I bond rate is published at TreasuryDirect.gov.
What is the savings bond purchase limit?
You can buy up to $10,000 in electronic EE or I bonds per year per Social Security number. An additional $5,000 can be purchased in paper I bonds using your tax refund, for a maximum of $15,000 in I bonds per year.
Are savings bonds taxable?
Interest from US savings bonds is exempt from state and local income tax but is subject to federal income tax. EE bonds used for qualifying education expenses may be fully or partially excluded from federal tax under the Education Savings Bond Program.
