10-year Treasury yield vs inflation
The 10-year Treasury yield is a nominal rate that decomposes into two pieces: the real yield (compensation for lending after inflation) and the breakeven inflation rate (the market's average CPI forecast over the next 10 years). Nominal 10Y = 10Y real yield (TIPS) + 10Y breakeven. When the nominal yield rises but breakevens are flat, real yields are doing the work - usually tighter financial conditions, a headwind for equities and duration. When nominal rises because breakevens rise, the market is repricing inflation, not growth. Watching all three together tells you whether a yield move is about inflation, real growth, or term premium.
- Nominal 10Y
- The headline Treasury yield. Sum of real yield + expected inflation + term premium.
- 10Y breakeven
- Nominal 10Y minus 10Y TIPS. The market's forward inflation expectation.
- 10Y real yield
- TIPS yield. Drives risk assets, gold, and the dollar more than the nominal print.
- Term premium
- Extra yield demanded for duration risk. Rises with supply, QT, and policy uncertainty.
The decomposition
The 10-year nominal Treasury yield is not one number - it's three:
- Real yield (from 10Y TIPS): the inflation-adjusted rate investors earn
- Breakeven inflation: nominal 10Y − TIPS 10Y, the market's average CPI forecast
- Term premium: the residual - compensation for holding duration
A move in the nominal 10Y always resolves into a mix of these. Which one drove it determines what it means.
Four regimes to recognize
- Real yields up, breakevens flat - Tighter financial conditions. Bad for long-duration equities, gold, and EM. This was 2022 and much of 2023.
- Breakevens up, real yields flat - Inflation scare, growth intact. Commodities and cyclicals lead. Late 2020 through early 2021.
- Real yields down, breakevens down - Growth scare. Duration rallies, defensives lead. Recession-adjacent regimes.
- Both up - Overheating or fiscal supply shock. Term premium is often doing the work.
Why real yields matter more than nominal
Discount rates for every long-duration cash flow - equities, private assets, housing - are real, not nominal. A 5% nominal 10Y with 3% breakevens (2% real) is far more accommodative than a 4% nominal with 1% breakevens (3% real). Watching only the nominal print misses the actual signal for risk assets.
What to pair it with
- 5Y5Y forward breakeven - cleaner inflation-expectations gauge than spot breakevens
- ACM term premium estimate - separates supply/uncertainty premium from expectations
- DXY and gold - real yields lead both inversely
- Financial conditions indices - Chicago Fed NFCI, Goldman FCI
A single yield move is noise. The decomposition is the signal.
