BreakevenInflationen

Breakeven inflation, also known as the breakeven inflation rate, is a market-implied measure of expected average inflation over a specified horizon. It is calculated as the difference between the yield on a nominal government bond of a given maturity and the yield on an inflation-linked bond of the same maturity. For example, the difference between the 10-year nominal Treasury yield and the 10-year TIPS yield approximates the 10-year breakeven inflation rate. The concept stems from the Fisher equation and reflects market consensus on future inflation, incorporating various premiums and uncertainties.

The breakeven rate represents the inflation level that would make an investor indifferent between holding a nominal bond and an inflation-protected bond over the same period. It is a snapshot of expected inflation in the future, not a guaranteed outcome. The measure is commonly observed for multiple maturities (eg, 2, 5, 10, 30 years) and can be constructed from different country bond markets that offer nominal and inflation-linked securities.

Limitations and caveats include that the breakeven rate incorporates inflation risk premia and liquidity factors, which means it may diverge from actual realized inflation. Differences in tax treatment, inflation indexing methods (such as CPI variants), and market demand can also influence the spread. Consequently, the breakeven rate should be interpreted as a market-based expectation conditional on current prices, rather than a precise forecast.

Usage: policymakers and investors monitor breakeven inflation to gauge longer-run inflation expectations and to assess market positions, hedging strategies, and the term structure of expected inflation. It is one of several tools used to understand inflation dynamics in financial markets.
