Breakeven Inflation
Breakeven inflation is the yield on a regular government bond minus the yield on an inflation-protected bond of the same maturity. It is the inflation rate at which both would earn the same, and is used as a market estimate of expected inflation.
Markets offer two kinds of government bonds: ordinary ones with fixed payments, and inflation-protected ones whose principal follows prices. Comparing their yields reveals how much inflation investors are pricing in — the breakeven rate. Central banks, economists and traders watch it as a real-time gauge of inflation expectations. This entry explains how it is calculated, how to read it and what can distort it.

Breakeven inflation in plain words
An ordinary Treasury pays a fixed amount. A TIPS has a principal that rises and falls with a consumer price index.1 Both are backed by the US government, so the main difference between them is inflation.2
Subtract the TIPS yield from the ordinary bond yield of the same maturity: if inflation turns out higher than that gap, TIPS do better; if lower, the ordinary bond does better. The gap is the breakeven. See Treasury Inflation-Protected Securities and Real Yield.
How to read breakeven inflation, step by step
Find the nominal yield
For example the 10-year Treasury. See Treasury Bills, Notes and Bonds.
Find the TIPS yield
Same maturity.
Subtract
Breakeven ≈ nominal yield − TIPS yield.
Compare with targets
Many central banks aim for about 2% inflation.3
Watch changes
Rising breakevens suggest higher expected inflation.
Remember distortions
Liquidity and risk premiums also affect the gap.
Worked examples
Example 1 — The calculation
Calculation10-year Treasury yield 4.3%; 10-year TIPS yield 2.0%.
| Breakeven inflation | 4.3% − 2.0% = 2.3% |
Markets price in roughly 2.3% average inflation over ten years.
Example 2 — Which bond wins?
TIPS winUsing the breakeven of 2.3%, actual inflation averages 3.5% over the period.
| Result | TIPS outperform the ordinary bond |
Inflation above the breakeven favours inflation protection. See Inflation.
Example 3 — Market reaction
SignalAfter a hot inflation report, the 10-year breakeven rises from 2.2% to 2.5%.
| Signal | Higher expected inflation |
Breakevens react quickly to inflation news and policy expectations. See Consumer Price Index.
Measures of inflation expectations
| Aspect | Source | Strength / weakness |
|---|---|---|
| Breakeven inflation | Bond market prices | Real-time; affected by liquidity |
| Surveys | Households or economists | Direct; slower, can be biased |
| Inflation swaps | Derivatives market | Clean; less accessible |
| Central-bank forecasts | Policy makers | Informed; reflect policy goals |
Why breakeven inflation matters
Policy watching
Central banks track expectations closely. See Federal Reserve.

Advantages and disadvantages
Advantages
- Updated continuously by market prices.
- Easy to calculate from public yields.
- Directly comparable with inflation targets.
Disadvantages
- Includes liquidity and risk premiums, not just expectations.
- Can be distorted in market stress.
- Based on one specific price index.

A bet on inflation
Beginner
Choosing TIPS over ordinary Treasuries is effectively betting that inflation will exceed the breakeven.
Different horizons
Intermediate
Five-year breakevens react more to near-term inflation news; ten-year breakevens reflect longer-run expectations.
Liquidity premium
Advanced
TIPS usually trade less than ordinary Treasuries. In stressed markets, investors may sell TIPS, pushing their yields up and breakevens down even if inflation expectations have not changed.
Common mistakes
Treating breakeven as a forecast guarantee
It is a market price, not a promise.
Ignoring liquidity effects
Stress can distort the signal.
Comparing different maturities
Use the same maturity for both yields.
Forgetting the index
TIPS follow a specific consumer price index.
Check your understanding
Test yourself before moving on. Each answer comes with an explanation.
Key points to remember
- Breakeven = nominal yield − TIPS yield of the same maturity.
- It is the market’s implied average inflation.
- Above-breakeven inflation favours TIPS.
- Compare it with central-bank targets.
- Liquidity can distort it, especially in stress.
