Breakeven Trades and Linker Relative Value

A nominal Treasury bond's yield compensates investors for expected inflation plus a real return plus a term premium. A TIPS of the same maturity strips out the inflation compensation, paying a real return directly. Subtract the two yields and what's left, roughly, is the market's expected inflation rate over that maturity, plus a small risk premium for inflation uncertainty — the breakeven inflation rate. That single number is useful on its own, but it also opens the door to a family of relative-value trades once you start comparing breakevens across maturities, and across countries.

The basic building block

$$\text{Breakeven} \approx \text{Nominal yield} - \text{Real yield (TIPS)}$$

In words: the gap between what a nominal bond yields and what an inflation-protected bond of the same maturity yields is, approximately, the average inflation rate the market needs to see over that period for the two investments to have paid off equally. Buying TIPS and shorting nominals, DV01-matched, is a bet that realized inflation comes in above the current breakeven; the reverse trade bets inflation disappoints relative to what's priced.

Worked example: an outright breakeven trade

The 10-year breakeven is currently 2.20%, and a desk believes tariff-driven cost pressures and sticky services inflation will keep realized CPI running closer to 2.6% on average over the next decade — above what's priced. They buy 10-year TIPS and short a duration-matched amount of 10-year nominal Treasuries. If, a year later, incoming data and Fed commentary shift market expectations so the 10-year breakeven rises to 2.45%, the TIPS will have outperformed the nominal bond by roughly that 25bp of breakeven widening (converted through each leg's duration), even before any inflation has actually been realized, because breakevens are forward-looking and this repricing happens well before the decade plays out.

Worked example: a breakeven curve trade

The 5-year breakeven sits at 2.35% while the 30-year breakeven sits at 2.15% — an inverted breakeven curve, unusual since long-run inflation expectations are typically anchored and shouldn't be more optimistic than near-term ones unless the market expects near-term inflation pressure (tariffs, supply shocks) to fade over time. A desk believing this inversion is overdone puts on a curve trade: short the 5-year breakeven (short 5y TIPS, long 5y nominal), long the 30-year breakeven (long 30y TIPS, short 30y nominal), DV01-matched on each leg. If near-term inflation pressures do fade as expected and the 5-year breakeven falls to 2.00% while the 30-year holds at 2.15%, the curve trade profits from the inversion narrowing, regardless of whether the outright level of either breakeven ends up higher or lower than today.

What this means in practice

Breakeven trades let macro desks express a view on inflation without taking real-rate duration risk, since the TIPS and nominal legs largely cancel real-rate exposure and leave only inflation-expectations exposure. Cross-country breakeven trades (US breakevens versus UK or Eurozone breakevens) extend the same logic to bet on which economy's inflation outlook is more mispriced relative to the other.
