What Are TIPS? Treasury Inflation-Protected Securities Explained
TIPS (Treasury Inflation-Protected Securities) protect your savings from inflation. Here's how they work, what they pay, and when they make sense.
Inflation is the silent killer of savings. A 3% inflation rate turns $100,000 into $74,000 of purchasing power in 10 years — even if the account balance shows $100,000. Treasury Inflation-Protected Securities (TIPS) are U.S. government bonds specifically designed to prevent that erosion.
How TIPS Work
TIPS have two components: the principal (face value) and the interest rate (coupon). The unique feature: the principal adjusts with inflation (measured by CPI) every 6 months. If inflation rises 3%, a $10,000 TIPS becomes a $10,300 bond. Your interest payments are a fixed percentage of the adjusted principal — so both the principal and interest grow with inflation.
TIPS vs Regular Treasury Bonds
- Regular T-bond: $10,000 at 4% → always pays $400/year, always redeems at $10,000
- TIPS: $10,000 at 1.5% real yield → after 10 years of 3% inflation, principal is $13,439, final payment ~$13,439
- TIPS protects purchasing power; regular bonds do not
- TIPS coupon rates are lower because inflation protection has value
What Is the 'Real Yield'?
TIPS are quoted by their real yield — the return above inflation. A TIPS with a 1.5% real yield at 3% inflation delivers an effective 4.5% nominal return. When real yields are positive (as in 2023–2024), TIPS are particularly attractive. When real yields are negative, you're accepting a return below inflation.
How to Buy TIPS

- Brokerage account: Purchase TIPS on the secondary market
- TIPS ETFs: TIP (iShares), SCHP (Schwab), VTIP (Vanguard) — easy diversification
- TIPS mutual funds: Available in many 401(k) plans
The Tax Catch: Phantom Income
Here's the important wrinkle: the inflation adjustment to TIPS principal is taxable in the year it occurs — even though you don't receive that money until the bond matures. This 'phantom income' makes TIPS tax-inefficient in taxable accounts. Best practice: hold TIPS in a tax-advantaged account (IRA, 401k) where phantom income isn't a problem.
When TIPS Make Sense
- You're retired or near retirement and protecting purchasing power matters most
- You're worried about higher-than-expected inflation
- Real yields are attractive (above 1%)
- You hold them in a tax-advantaged account to avoid phantom income tax
💡 Tip: I Bonds are a TIPS alternative for smaller amounts. They also adjust with inflation, have no phantom income tax issue, and can be bought at TreasuryDirect.gov — up to $10,000/year per person.
