U.S. Treasury securities are debt instruments issued by the federal government, backed by the full faith and credit of the United States.
32 steps across 8 sections
1. TreasuryDirect (www.treasurydirect.gov)
- The only way to buy I Bonds and EE Bonds
- Also sells T-Bills, T-Notes, T-Bonds, TIPS, and FRNs via non-competitive auction
- No fees for opening an account or purchasing
- Minimum purchase: $25 for savings bonds, $100 for marketable securities
- Requires: Social Security number, U.S. address, bank account for funding
- Limitation: No secondary market access; must hold to maturity (or cash savings bonds after 1 year)
2. Through a Brokerage (Fidelity, Schwab, Vanguard, E*TRADE, etc.)
- Can buy T-Bills, T-Notes, T-Bonds, TIPS, and FRNs at auction or on the secondary market
- Cannot buy I Bonds or EE Bonds through brokerages
- Many brokerages charge $0 commission for Treasury purchases (Fidelity, Vanguard, Schwab)
- Advantage: Can sell before maturity on the secondary market (at market price)
- Advantage: Better portfolio integration and reporting
3. Through Treasury Bond ETFs/Mutual Funds
- ETFs like SHY (short-term), IEF (intermediate), TLT (long-term), TIP (TIPS)
- Provides diversification and instant liquidity
- Management fees apply (typically 0.03-0.15%)
- Does not provide the same "hold to maturity" guarantee as individual bonds
4. Current Rates (Through April 2026)
- Composite rate: 4.03% annualized
- Fixed rate component: 0.90% (locked for life of the bond)
- Inflation rate component: 1.55% semi-annual (adjusts every 6 months based on CPI)
- Next rate reset: May 1, 2026 (new rates for May-October 2026 purchases)
5. How I Bond Rates Work
- Composite rate = Fixed rate + (2 x semi-annual inflation rate) + (fixed rate x semi-annual inflation rate)
- The fixed rate is set at purchase and never changes for that bond
- The inflation rate resets every 6 months (May and November) based on CPI-U changes
- Your bond's rate resets on the 6-month anniversary of purchase
6. I Bond Purchase Limits
- Trusts, businesses, and entities can also purchase $10,000/year each
- Gift purchases: You can buy I Bonds as gifts (delivered to recipient's TreasuryDirect account), but they count against the recipient's $10K limit in the year delivered
7. I Bond Redemption Rules
- Cannot cash before 12 months from purchase date
- Early redemption penalty (months 12-60): Forfeit the last 3 months of interest
- After 5 years: No penalty; can cash at any time for full value
- Maturity: 30 years (stops earning interest after 30 years)
8. I Bond Tax Advantages
- Federal income tax: Interest is taxable but can be deferred until redemption or maturity
- State and local tax: Completely exempt from state and local income tax
- Education tax exclusion: Interest may be tax-free if used for qualified higher education expenses (income limits apply; must be 24+ years old; bond must be in parent's name, not child's)
Common Mistakes
- Not maxing out I Bonds before other fixed income
- Buying I Bonds right before a rate reset
- Forgetting the 1-year lockup
- Ignoring the 3-month interest penalty
- Not using the tax refund paper bond option
Pro Tips
