TIPS — Treasury Inflation-Protected Securities Explained
Complete guide to TIPS — Treasury Inflation-Protected Securities. How they work, current yields, comparison with I Bonds, and whether they belong in your 2026 portfolio.
What Are TIPS?
TIPS — Treasury Inflation-Protected Securities — are US government bonds whose principal adjusts with inflation. They're one of the few investments that directly protect your purchasing power against rising prices.
TIPS are issued by the US Treasury in 5-year, 10-year, and 30-year maturities. They trade on the secondary market, making them far more liquid than savings bonds like I Bonds.
TIPS are among the most popular inflation hedges for both individual and institutional investors. They combine the safety of US Treasuries with automatic CPI adjustment — your principal literally grows with inflation.
How Does TIPS Pricing Work?
TIPS have two components that determine your total return:
| Component | Description |
|---|---|
| Fixed coupon rate | Set at auction (currently ~1.5–2% for 10-year) |
| Inflation adjustment | Principal adjusts semiannually based on CPI-U |
| Total return | Coupon payments on adjusted principal + principal growth |
The coupon rate stays fixed for the life of the bond, but it's applied to your inflation-adjusted principal. So as inflation rises, both your principal and your coupon payments grow.
Interest is paid semiannually based on the adjusted principal. At maturity, you receive the greater of the adjusted principal or the original face value — so deflation can't reduce your principal below what you invested.
Example: How Much Could You Earn?
Suppose you invest $10,000 in 10-year TIPS with a 1.75% real yield, and inflation averages 3.5%, 3.0%, and 2.5% over the first three years:
| Year | Adjusted Principal | Coupon Payment | Total Annual Return |
|---|---|---|---|
| 1 | $10,350 | $181 | $531 |
| 2 | $10,661 | $187 | $497 |
| 3 | $10,927 | $191 | $457 |
Over the full 10-year term with average 3% inflation and a 1.75% real yield, your $10,000 would grow to roughly $16,000–$17,000 before taxes.

Who Should Buy TIPS?
TIPS are an excellent choice if you:
- Want inflation protection without purchase limits — unlike I Bonds ($10K/year cap), you can buy TIPS in any amount
- Value semiannual income — coupon payments every 6 months provide regular cash flow
- Need secondary market liquidity — sell anytime if you need your money before maturity
- Are building a diversified portfolio — TIPS are a proven "safety core" for long-term investors
TIPS vs I Bonds — Which Inflation Hedge?
This is the most common comparison. I Bonds have a higher composite rate for small investors and better tax treatment (you can defer taxes and potentially avoid them for education). But I Bonds are capped at $10,000/year and locked for 1 year. TIPS have no purchase limit, trade freely, and come in multiple maturities. Rule of thumb: max out I Bonds first, then use TIPS for additional inflation protection.
TIPS vs Regular Treasury Notes — Inflation vs Fixed?
Standard Treasury Notes pay a higher nominal coupon but offer zero inflation protection. If inflation stays below ~2.5%, regular Treasuries may outperform TIPS. But if inflation rises above 3–4%, TIPS will deliver significantly better real returns.
