How To Start A TIPS Ladder To Protect Against Unexpected Inflation

Build a TIPS ladder by buying individual TIPS bonds maturing in consecutive years (e.g., every year for the next 10 years) and holding each bond to maturity, which locks in real yields and ensures principal adjusts upward with CPI regardless of future inflation surprises. The ladder fails as inflation protection if you might need to sell bonds before maturity, since TIPS prices can fall when real yields rise.

Build a tips ladder that works even when inflation surprises you

Build a TIPS ladder by buying individual TIPS bonds maturing in consecutive years (e.g., every year for the next 10 years). Hold each bond to its final payment date. This locks in real yields. It also ensures principal adjusts upward with CPI regardless of future inflation surprises. The ladder fails as inflation protection if you might need to sell bonds before their scheduled end date. TIPS prices can fall when real yields rise. For the self-directed investor who already understands TIPS mechanics, a rolling ladder is a deliberate portfolio structure, not a convenience product. It forces you to define your time horizon, your cash-flow needs, and your reinvestment discipline before you place a single order.

Why funds don't work for this specific goal

A TIPS ETF or mutual fund holds hundreds of bonds but never returns your principal in a predictable way. You own a slice of a continuously revolving portfolio. Its net asset value (NAV) drops when real yields spike. That spike is exactly what happens during an unexpected inflation shock. The Fed raises rates to cool the economy. Real yields jump. Your fund’s price falls even though the CPI adjustment is rising. If you need to sell shares to pay a bill during that window, you lock in a nominal loss. Individual TIPS held to their natural conclusion avoid this entirely. The Treasury guarantees you receive the inflation-adjusted par value at the end, regardless of what the secondary market quotes on any given Tuesday. The fund’s “rolling” nature means you never reach a final payoff date. You are permanently exposed to interest-rate risk. A ladder with fixed rungs converts that risk into a known sequence of cash flows.

Picking your rungs and time horizons

Decide how many years of spending you want to protect. If you need real purchasing power for the next decade, build 10 rungs spaced one year apart. The face value you need for each rung is set by your own spending plan. For a rolling ladder meant to guard against surprise inflation rather than match a single liability, use a 5-year or 7-year maximum term. Shorter ladders sacrifice yield but reduce the chance that a sudden rate spike crushes the mark-to-market value of your longer rungs. Space rungs evenly. Annual spacing is simplest. Semi-annual spacing works if you prefer smaller, more frequent reinvestments. Match your rung size to your actual spending spike risk. If a big tax bill or tuition payment looms in year 3, make that rung larger. Do not extend beyond 10 years for a pure inflation-protection ladder. The real yield premium for 20-year TIPS rarely compensates for the added duration risk. You can always roll maturing proceeds forward.

Executing the auction and secondary market buys

Buy newly issued TIPS at TreasuryDirect auctions for the specific years you need. Understand that the Treasury only issues 5-year, 10-year, and 30-year TIPS on a regular schedule. A 3-year or 7-year rung requires a secondary market purchase through a brokerage account. At your broker, search for “TIPS” and filter by the date the bond comes due. You will see bonds quoted with a real yield to the end, an inflation factor (index ratio), and a dirty price that includes accrued interest. Place limit orders no wider than two ticks above the best ask. Confirm the yield is positive after the inflation factor is applied. A negative real yield means you are paying for inflation insurance, which might still be rational for a liability you must meet. For the auction route, check the Treasury’s auction calendar in January for the year’s dates. Your desired term might not have an auction until months later. Buy a shorter-term TIPS in the secondary market now and let it roll into the missing rung when the auction occurs. Keep settlement dates in mind. TIPS settle T+1 for new issues and T+2 for secondary trades. Fund your cash account accordingly to avoid a margin call.

What to do with the proceeds when a rung comes due

When a rung reaches its end, you receive the inflation-adjusted principal. This is the original face value multiplied by the cumulative CPI adjustment over the bond’s life. You also receive the final coupon. If that cash covers a near-term expense you identified when building the ladder, spend it. That is the point of the structure. If you do not need the cash, reinvest it into a new long rung to keep the ladder’s average duration constant. A new 10-year TIPS is one option. Park it in a money market fund if real yields on new TIPS are unattractive. But if inflation has already materialized and CPI is running hot, shift the proceeds into short-term TIPS (1-2 years) rather than rolling into a long bond. Locking in a low real yield for a decade after a spike is a classic mistake. The ladder’s discipline forces you to revisit your inflation expectations every time a rung concludes. You never drift into a passive “buy and hold forever” posture that leaves you exposed to a single rate regime.

Frequently asked questions

What is the minimum amount I need to start a TIPS ladder?

Individual TIPS trade in increments set by the Treasury at $1,000 face value. A 5-rung ladder therefore costs at least $5,000 plus accrued interest and any inflation adjustment already built into the price. For a 10-rung ladder, plan on a minimum face value of $10,000 across all rungs. You can buy smaller portions of each rung in the secondary market if your broker allows odd lots. Check the TreasuryDirect website for current auction minimums and your broker’s bond desk for secondary market lot sizes.

How does a TIPS ladder compare to I Bonds for inflation protection?

I Bonds have a purchase limit set by the Treasury at $10,000 per person each calendar year. They cannot be redeemed for the first year. This makes them useless for a sudden inflation spike in year one. TIPS have no purchase limit and can be sold anytime. But they lose principal if you sell before the scheduled end during a rate spike. I Bonds never lose principal if held for five years. Visit TreasuryDirect for the current I Bond fixed rate and purchase rules.

Should I buy TIPS in a tax-advantaged account or taxable account?

Hold TIPS in a retirement account like an IRA. The inflation adjustment is taxed as ordinary income each year, even though you do not receive the cash until the bond concludes. In a taxable account, you pay tax on phantom income. This reduces your real return. In an IRA, the tax is deferred until withdrawal. That preserves your compounding.

What happens to my ladder if deflation occurs?

If CPI falls, the principal adjusts downward. The Treasury guarantees you receive at least the original face value at the final payoff date if you hold to term. Deflation reduces the coupon payment because it is a fixed percentage of the adjusted principal. Your real purchasing power is protected. You just get no inflation bonus.
