What Is the Inflation Risk Premium and How Is It Measured?
The inflation risk premium is the additional return nominal bond investors demand for bearing inflation uncertainty — beyond expected inflation. It is embedded in the breakeven inflation rate: breakeven = expected inflation + inflation risk premium. The inflation risk premium expands in Stagflation/Reflation (high inflation uncertainty) and compresses in Goldilocks/Deflation (low uncertainty). Rising breakeven rates can signal either rising inflation expectations or rising inflation risk premium — the distinction matters for regime analysis.

Breakeven Inflation Decomposition
The 10-year breakeven inflation rate (the yield difference between nominal Treasuries and TIPS) is the most widely used market-based inflation expectation measure. But it conflates two components: expected inflation (the market's best estimate of future CPI) and the inflation risk premium (compensation for uncertainty around that estimate).
When breakeven rates rise, it could mean: (a) the market expects higher inflation, or (b) the market is demanding higher compensation for inflation uncertainty, or (c) both. Distinguishing between these requires term structure models. AhaSignals uses the NY Fed's inflation risk premium estimates as a reference.

Known Limitations
- Inflation risk premium estimates are highly model-dependent
