Constructing a 5-Year TIPS Ladder to Lock in 2026 Purchasing Power

With inflation showing persistent stickiness into 2026, investors seeking preservation of capital are looking beyond nominal yields. The primary threat to fixed-income portfolios is not just default risk—which is minimal for sovereign debt—but the erosion of purchasing power. A Treasury Inflation-Protected Securities (TIPS) ladder offers a mechanical solution to this problem, providing a contractual adjustment of principal based on the Consumer Price Index for All Urban Consumers (CPI-U).

Constructing a ladder requires precision. It is not merely purchasing a fund; it is engineering a series of cash flows that mature exactly when liquidity is needed, regardless of the price level at that time.

Quantifying the Real Liability

The first step involves ignoring the nominal dollar amount and focusing entirely on the spending requirement in today's terms. For an investor planning to fund a liability of $50,000 in 2027, that $50,000 represents a specific basket of goods. If the CPI rises by 3% over the next year, $51,500 will be required to purchase that same basket.

To build the ladder, one must map out the exact real spending needs for the next five years—2027 through 2031. A common error is over-purchasing to hedge against worst-case scenarios. The efficiency of a TIPS ladder comes from matching the principal to the actual liability. By determining the required real annual income, the investor establishes the "face value" needed for each rung of the ladder.

For example, if the goal is to generate $30,000 of real income annually, the ladder must hold $30,000 in face value of TIPS maturing each year. The coupon payments—currently hovering around 2.0% to 2.5% for many issues in the current market—will arrive every six months, but the inflation adjustment accrues daily to the principal, paid out upon maturity.

Selecting the Specific Maturities for a Five-Year Horizon

Once the real liability is quantified, the next action is selecting the specific CUSIPs. The United States Treasury issues TIPS with original maturities of 5, 10, and 30 years. For a five-year ladder ending in 2031, an investor might utilize a combination of new issues and "on-the-run" securities available in the secondary market.

As of March 2026, the market offers 5-year TIPS maturing in 2031, 10-year notes maturing in 2034 and 2035, and 30-year bonds extending to 2055. To build the 2027–2031 ladder, one must identify the specific issues maturing in January of each target year (or July, depending on liquidity preference).

The specific yield on each rung will vary. The yield curve for real rates is rarely flat. Currently, the 5-year real rate might differ from the 10-year real rate by 20 to 30 basis points. Investors must accept the market-determined yield for each specific maturity rather than trying to time the entry point across the entire curve. It is often beneficial to review the mechanics of rolling down the yield curve to understand how holding these securities changes as they approach maturity.

The selection process involves calculating the cost to acquire $1,000 of inflation-adjusted principal at maturity. Since TIPS trade based on their inflation-adjusted principal (the "Accrued Principal"), the price paid will be the quoted clean price plus the index ratio.

Executing the Purchase at Auction vs. Secondary Market

Execution involves a choice between participating in Treasury auctions or buying on the secondary market through a brokerage. Auctions offer the advantage of buying at the "average yield" accepted by the Treasury, typically without paying a transaction fee or markup to a dealer.

However, auctions only occur at specific intervals. The 5-year TIPS auction typically happens in April and October. If an investor is building the ladder in March 2026, waiting for an April auction might be feasible for the 2031 maturity, but the 2027 or 2028 rungs might require immediate secondary market purchases.

When buying on the secondary market, the investor pays a bid/ask spread. Dealers often mark up the price significantly on smaller lots. It is standard practice to check the pricing against the benchmark yields published by the Federal Reserve Bank of New York to ensure the markup is reasonable—generally kept under a few cents on the dollar.

The order entry must specify the face value amount, not the dollar cost. If an investor needs $30,000 of real value in 2028, they place an order for $30,000 face value. The settlement amount will be higher or lower depending on the inflation index ratio and the price (above or below par).

Mitigating the Tax Drag on Inflation Adjustments

A critical, often overlooked component of TIPS ownership is the tax treatment. In a taxable account, the phantom income tax creates a significant drag. The IRS taxes the annual inflation adjustment of the principal as ordinary income in the year it occurs, even though the investor does not receive that cash until the bond matures.

This means if inflation spikes to 5%, the investor receives a 1099-OID (Original Issue Discount) for that 5% increase and owes taxes on it, despite receiving no cash distribution to pay the tax. This necessitates holding liquidity outside the ladder to settle the tax bill.

For investors in high tax brackets, this tax drag can sometimes erode the real benefit of holding TIPS. In some jurisdictions, investors weigh this against Municipal Bonds which offer tax-free interest but lack the inflation principal adjustment. The decision comes down to the investor's marginal tax rate versus their expectation of long-term CPI growth.

Holding TIPS in tax-advantaged accounts like IRAs or 401(k)s eliminates this problem, as the tax is deferred or exempt. Ideally, a TIPS ladder resides entirely within a tax-sheltered wrapper to maximize efficiency.

Managing Deflation Risk and the Floor

While the focus is usually on inflation, a TIPS ladder also provides deflation protection that a nominal Treasury ladder does not. TIPS come with a deflation floor: at maturity, the Treasury redeems the bond for the greater of the original principal or the inflation-adjusted principal.

In a disinflationary or deflationary scenario, the nominal value of the TIPS decreases. However, the investor still receives the original face value at maturity. This feature makes the 5-year rung of the ladder effectively a deflation put option. If prices fall, the purchasing power of the returned principal increases.

Structuring the ladder requires acknowledging that the coupon rate is fixed. If real rates rise from 2% to 3% after purchase, the market value of the TIPS will drop. However, because the strategy involves holding to maturity, these price fluctuations are irrelevant—often referred to as "paper losses"—provided the credit quality remains absolute. Unlike corporate bonds nearing distress, US Treasury credit risk is not a variable here.

Reinvestment and Ladder Extension

The final step involves managing the cash flow as the first rung matures in 2027. When the bond matures, the investor receives the inflation-adjusted principal. At this junction, the decision must be made whether to spend the cash or reinvest it to extend the ladder.

If the original liability persists (e.g., living expenses), the matured principal is used to purchase a new TIPS bond maturing in 2032. This "rolling" mechanism extends the duration of the ladder. The investor is subject to the prevailing real interest rates at the time of reinvestment.

If rates are higher in 2027 than they were in 2026, the ladder's yield improves. If rates are lower, the yield resets lower. This uncertainty regarding the reinvestment rate is the primary risk of the ladder strategy compared to a single long-duration bond, though it offers greater liquidity and flexibility.

Constructing a TIPS ladder is an exercise in certainty. It trades the potential for higher nominal returns from equities or corporate credit for the mathematical assurance of purchasing power. By matching specific maturities to real liabilities, the investor removes the variable of inflation from the financial equation, focusing instead on managing the tax implications and reinvestment rates.
