US Treasury securities are the safest investment in the world — backed by the full faith and credit of the US government. In 2026, with yields still elevated from the Fed rate cycle, they offer compelling returns for conservative investors.

The state tax advantage
Treasury interest is exempt from state and local income tax. In California (13.3% top rate), an investor in the top bracket: a 4.8% T-bill is equivalent to a 5.44% taxable yield. This advantage is significant in high-tax states.
How to buy Treasuries
- TreasuryDirect.gov: Buy directly from the government, no fees, minimum $100. Hold to maturity — limited secondary market through TreasuryDirect.
- Brokerage (Fidelity, Schwab, Vanguard): Buy on secondary market or at auction. Full secondary market liquidity. Most convenient option.
- ETFs (BIL for T-bills, IEF for 7–10yr notes, TLT for 20+yr): Instant liquidity, diversified, but ongoing expense ratio eats some yield.
