What Are Breakeven Inflation Rates and How Do You Read Them?
Breakeven inflation rates are the market’s implied expectation for average inflation over a given period. They are derived from the gap between nominal Treasury yields and TIPS yields. Rising breakevens signal increasing inflation expectations — a key input for central bank policy and asset allocation.

The short answer
Treasury Inflation-Protected Securities (TIPS) pay a return that adjusts with inflation. Regular Treasuries pay a fixed return regardless of inflation. The difference between the two yields tells you what the bond market expects inflation to average over that period.
If the 10-year nominal Treasury yields 4.5% and the 10-year TIPS yields 2%, the breakeven is 2.5%. This means the market expects inflation to average 2.5% per year over the next decade. If actual inflation exceeds 2.5%, TIPS holders profit. If it runs below, nominal bondholders win.
Breakevens are not a forecast — they’re a consensus price. Like any market price, they reflect the balance of opinion, positioning, and liquidity at a given moment. But they are the single best real-time measure of inflation expectations available.

What the data shows
Using FRED data (T10YIE for 10-year and T5YIE for 5-year breakevens, 2003–2024), several patterns emerge.
The 10-year breakeven has averaged approximately 2.1% since 2003 — close to the Fed’s 2% inflation target. It has ranged from a low of 0.5% during the March 2020 liquidity panic to a peak of 3.0% in April 2022 at the height of the inflation surge.
The 5-year breakeven is more volatile and reflects nearer-term expectations. It peaked at 3.6% in March 2022 and fell back below 2.5% by mid-2023 as core inflation decelerated. The spread between 5-year and 10-year breakevens provides additional information: when the 5-year exceeds the 10-year, markets expect inflation to be higher in the near term but to moderate over time (the 2022 pattern).
The most dramatic breakeven collapse occurred in March 2020, when 10-year breakevens crashed from 1.7% to 0.5% in two weeks — not because markets expected deflation, but because a liquidity crisis forced indiscriminate selling of TIPS. This illustrates a critical limitation: breakevens can be distorted by liquidity conditions, not just inflation expectations.

Why it happens — the macro mechanism
Breakevens reflect three components, not just inflation expectations:
Inflation expectations are the primary driver. When investors believe inflation will be higher, they demand more compensation on nominal bonds (pushing nominal yields up) or accept lower yields on TIPS (which adjust for inflation). The breakeven widens.
The inflation risk premium is embedded in nominal yields. Investors holding nominal bonds face uncertainty about future inflation — they may demand extra yield as compensation for this risk, even if their point estimate of inflation hasn’t changed. This means breakevens can overstate expected inflation during volatile periods.
Liquidity premium affects TIPS yields. The TIPS market is smaller and less liquid than the nominal Treasury market. During stress periods, the liquidity discount on TIPS can widen, pushing TIPS yields up and compressing breakevens — even when inflation expectations are actually rising. The March 2020 crash was an extreme example.
The Fed monitors breakevens closely as a real-time gauge of whether inflation expectations remain “anchored” near 2%. If 10-year breakevens persistently exceed 2.5%, it signals that the market doubts the Fed’s ability to control inflation — a direct threat to the credibility that underpins the entire monetary policy framework.
Breakevens don’t predict inflation. They price the market’s belief in the central bank’s ability to control it.

What it means for different economic actors
Bond investors use breakevens to decide between nominal Treasuries and TIPS. If you expect inflation to exceed the current breakeven, TIPS are the better investment. If you expect inflation to run below the breakeven, nominal bonds outperform. The decision is essentially a bet on whether the market’s inflation consensus is too high or too low.
Equity investors should watch breakevens as a leading indicator for Fed policy. Rising breakevens increase the probability of tightening, which tends to pressure equity valuations — especially long-duration growth stocks. Falling breakevens suggest easing may be ahead, which is typically supportive for risk assets.
Savers can use breakevens as a quick benchmark: if your savings account yields less than the 5-year breakeven, you are expected to lose purchasing power over that horizon. This simple comparison cuts through the complexity of inflation measurement.
A frequent error is treating breakevens as a precise forecast. They are a market price — subject to supply/demand dynamics, positioning, and liquidity distortions. During the 2021–2022 inflation surge, actual CPI consistently exceeded breakeven-implied levels, demonstrating that markets systematically underestimated the inflation risk.

Frequently asked questions
What is the 5-year, 5-year forward breakeven?
This measures expected average inflation from year 5 to year 10 — stripping out near-term noise. The Fed watches this measure closely because it captures long-term expectations, which are the most important for monetary policy credibility. If this measure exceeds 2.5% persistently, it suggests inflation expectations are becoming unanchored.
Can breakevens be negative?
Technically, yes — and they briefly approached zero during the March 2020 crisis. Negative breakevens would imply the market expects deflation. This has occurred in Japan and briefly in the Eurozone during severe economic downturns. In the U.S., persistently negative breakevens would signal a deflation trap — a scenario the Fed has fought aggressively to avoid since 2008.
Are TIPS a good inflation hedge?
Over their full holding period, yes — TIPS provide a guaranteed real return if held to maturity. However, TIPS can lose value in mark-to-market terms during rising real rate environments (2022 saw significant TIPS losses despite high inflation) because their price is sensitive to real yield changes. TIPS hedge inflation risk but not interest rate risk.
