Three shapes
Each tells a different story.
- →Normal — long > short. Expansion conditions.
- →Flat — long ≈ short. Mid-cycle, growth uncertainty.
- →Inverted — long < short. Late cycle; bond market pricing future cuts.
Recession indicator
T10Y2Y has inverted before every US recession since 1955. Lag from inversion to recession is usually 12–18 months.
Why traders care
Beyond predicting recessions, the curve drives everything.
- →Bank margins — banks borrow short, lend long. Flat/inverted squeezes margins.
- →Equity rotation — steepening favours cyclicals; flattening favours defensives.
- →FX — steeper curves often outperform on growth optimism.
- →Real estate — long-end drives mortgage rates.
