Wall Street has spent 2026 arguing about artificial intelligence the way a family argues about politics at Thanksgiving: loudly, endlessly, and with nobody changing seats. Meanwhile, in the quietest corner of the market, the United States Treasury is making an offer so good we had to read it twice.
The offer sits on a security called TIPS — Treasury Inflation-Protected Securities. A TIPS is a government bond whose value rises with inflation, so the yield it pays is “real”: it lands on top of whatever inflation does. Long-dated TIPS now pay nearly 3% real. Guaranteed, for decades, by the same government that prints the inflation.
Compare that with the regular 30-year Treasury bond, which pays a bit over 5.2%. That sounds richer, but it is a fixed promise — if inflation runs hot for 30 years, the 5.2% gets quietly eaten from the inside. The TIPS holder does not care. Whatever inflation does, they collect roughly 3% on top of it. That is the highest guaranteed real yield in decades.
The other side
Now look at what stocks offer for the same long-term money. One classic yardstick compares stock prices with ten years of company earnings. By that measure, the S&P 500 sits in its highest few percentiles ever. When prices are that high relative to earnings, history says the long-run return after inflation tends to be low. The seesaw has rarely tilted this far: stocks priced for near record-low real returns, TIPS priced for near record-high ones.
The standard rebuttal is that AI changes everything, so the old math no longer applies. Maybe! But the last time the U.S. market began a 30-year boom, it was 125 years ago, powered by cars, planes, electricity and radio all at once. AI may beat them all. We do not know. And “we do not know” is exactly the condition a guaranteed 3% real is built for.
| Long-term money, four ways | What it pays | The catch |
|---|---|---|
| Long-dated TIPS | ~3% real | Guaranteed above inflation; prices swing if real yields move; awkward taxes (see below) |
| 30-year Treasury | ~5.2% before inflation | No inflation protection — 30 years of hot inflation eats it from the inside |
| S&P 500 at today’s prices | Real return near historic lows (implied) | Unless AI outruns cars, planes, electricity, and radio combined |
| T-bill ladder | Short-term rate, resets | Superb for cash; guarantees nothing beyond the next roll |
Two warnings
First, the tax problem. When inflation pushes a TIPS’ value up, the IRS taxes that increase every year even though you did not receive it in cash. Investors call it “phantom income” — real taxes on paper gains. The fix is simple: hold TIPS through funds, inside retirement accounts like an IRA or 401(k). Not in the regular brokerage account. We mean it.
Second, TIPS protect against inflation, not against panic. In 2008, when everyone needed cash at once, long TIPS sold off hard alongside everything else. Anyone forced to sell mid-panic learned the guarantee only fully applies to those who can hold. Long-dated means long-held.
The action
Now the part where this stops being commentary. Most weeks, an idea like this goes on our watch list to be admired. This week we acted: a starter position in the PIMCO 15+ Year U.S. TIPS Index ETF (LTPZ) joins our income holdings — in retirement accounts only, for the phantom-income reason above.
It sits beside our Treasury-bill ladder and our dividend payers, and it follows the same discipline as everything else we own for income: we can say, in one sentence, exactly where the money comes from. Here the sentence is short. It comes from the U.S. Treasury, and it is promised in purchasing power, not paper dollars.
One honest caveat. LTPZ is a fund, not a single bond, so it never matures — there is no fixed date when you get your money back. You earn that real yield by holding while the share price moves with interest rates. We are starting small and letting the math talk.
