CPI tells you what inflation did last month. The breakeven rate tells you what the bond market thinks inflation will average for the next ten years — and it updates daily instead of monthly.
When breakevens move sharply, the professional inflation narrative is changing in real time. That usually happens days or weeks before the data confirms it, and long before retail traders notice.
Here's a question worth sitting with: if you wanted to know what inflation was going to be, would you rather have an economist's opinion or a number that thousands of institutions are actively betting billions on?
That second number exists. It's published every business day, it's completely free, and most retail traders have never heard of it.
What a TIPS Breakeven Rate Actually Is
The U.S. Treasury sells two kinds of bonds. Regular ones pay a fixed rate. TIPS — Treasury Inflation-Protected Securities — have their principal adjusted with the Consumer Price Index, so the holder is compensated for whatever inflation actually turns up.
Compare the yields on those two and something useful falls out. Subtract the TIPS yield from the equivalent nominal Treasury yield, and the gap is the breakeven inflation rate:
| Component | Illustrative value |
|---|---|
| 10-year nominal Treasury yield | 4.28% |
| 10-year TIPS yield (real yield) | 1.90% |
| 10-year breakeven rate | 2.38% |
The name is literal. At 2.38% average inflation over ten years, both bonds return the same thing — you break even. Above that, TIPS win. Below it, the nominal bond wins.
Which means the breakeven is the level of inflation at which the market is genuinely indifferent between the two. It is, quite precisely, the market's collective forecast with capital behind it.
The Three Breakevens Worth Watching
You'll see several maturities quoted. Each answers a different question, and knowing which one to pull up matters more than watching all of them.
| Measure | What it captures | Best used for |
|---|---|---|
| 5-year breakeven | Expected average inflation over five years | Near-term pressure. Reacts hardest to energy prices and current CPI surprises. |
| 10-year breakeven | Expected average inflation over a decade | The standard headline gauge, and the one most commonly quoted in market commentary. |
| 5-year, 5-year forward | Expected inflation for the five years starting five years from now | The Fed's preferred measure. Strips out today's noise entirely. |
Why the 5y5y Forward Is the One the Fed Actually Cares About
Near-term breakevens bounce around with oil prices. That's noise, and the Fed knows it — a spike because crude jumped tells you nothing about whether monetary policy is working.
The 5y5y forward removes that problem by skipping the first five years entirely. What's left is the market's view of inflation after current shocks have washed through — which is effectively a live scorecard on the Fed's credibility.
Central banking runs on belief. As long as people expect inflation to return to roughly 2%, they negotiate wages and set prices in ways that help deliver it. The expectation is partly self-fulfilling.
If the 5y5y forward drifts persistently higher, that mechanism is breaking — the market no longer believes the Fed will get inflation back to target. Expectations have become "unanchored," and history says restoring them requires far more tightening, and far more economic pain, than preventing the drift would have.
How to Read Breakevens Day to Day
The interpretation is refreshingly direct, which is rare in macro.
| Breakeven move | What the market is saying | Likely Fed implication |
|---|---|---|
| Rising | Inflation expectations building | Hawkish pressure — harder to justify cuts |
| Falling | Disinflation expected, or growth fears | Dovish room opening up |
| Collapsing fast | Deflation or recession fear | Emergency easing becomes plausible |
A useful habit: check the breakeven on CPI morning before the release. If breakevens have been drifting lower for two weeks and CPI comes in hot anyway, the bond market got it wrong — and those positions have to unwind, which amplifies the move well beyond what the print alone justifies.
What Breakevens Let You Predict
This sits in the leading-indicator stack for inflation alongside PPI and the ISM Prices Paid sub-indexes, but with one advantage neither of those has: it updates daily rather than monthly.
| What you watch | What it predicts | Lead time |
|---|---|---|
| 5-year breakeven trend | Near-term CPI direction | Days to weeks — often moves before the data confirms it |
| 5y5y forward drift | Fed policy stance over quarters | Months — this is the measure that keeps policy restrictive even as current inflation cools |
| Breakeven vs real yield split | Whether a bond selloff is inflation-driven or growth-driven | Immediate — and it's the cleanest read available on gold |
The Gold Connection Most Traders Miss
Gold doesn't track inflation. It tracks real yields — the nominal yield minus expected inflation, which is exactly what the TIPS yield already represents.
That's why gold sometimes falls during high inflation, confusing everyone who was told it's an inflation hedge. If nominal yields rise faster than breakevens, real yields go up, and gold gets crushed regardless of what CPI prints. If breakevens rise while nominal yields stay put, real yields fall and gold rallies.
Watching the 10-year TIPS yield directly is one of the most reliable gold signals available — considerably more useful than watching CPI headlines.
Where to Find Breakeven Data Free
The Federal Reserve Bank of St. Louis publishes all of these daily on FRED at no cost. Search for the 5-year, 10-year, and 5-year 5-year forward breakeven inflation series. The Treasury also publishes the underlying real yield curve directly.
No subscription, no terminal, no delay — daily institutional-grade inflation expectations data, which is genuinely unusual in a market where most useful things sit behind expensive paywalls.
Two Caveats Worth Knowing
Breakevens are excellent, not perfect, and both distortions matter at exactly the moments you most want the signal.
- They include risk premia. The number blends genuine inflation expectations with the extra compensation investors demand for bearing inflation uncertainty. So it's an expectation plus a premium, not a pure forecast.
- TIPS are less liquid than nominal Treasuries. In a genuine crisis, investors dump everything for the most liquid asset available, which distorts TIPS pricing. During the worst of 2008, breakevens collapsed far more than any realistic deflation forecast justified — that was liquidity panic, not an inflation view.
The practical rule: trust breakevens in normal conditions, treat them sceptically during liquidity stress, and always cross-check sharp moves against PPI and the ISM Prices Paid sub-indexes before acting.
Like every leading indicator on this site, breakevens tell you which way inflation expectations are shifting — not the CPI print itself.
