What is the 10Y-2Y spread?
By Market Ontology Research
The 10Y-2Y spread is the difference between the 10-year Treasury yield and the 2-year Treasury yield. When it goes negative - an inversion - it has preceded every US recession since 1969, with a lag of 6 to 24 months. It works because the 2Y reflects near-term Fed policy expectations and the 10Y reflects long-run growth and inflation. When near-term policy is tighter than long-run growth, recession risk is elevated. The signal weakens when the term premium is distorted by QE/QT.
- Inversion signal
- Negative spread historically precedes recession by 6-24 months.
- Steepening signal
- Spread re-steepening after inversion often coincides with the recession itself.
- False positives
- 1966, 1998 inverted without immediate recession.
- Watch with credit
- Inversion + widening HY OAS is a stronger combined signal.
What it measures
- 2Y yield - market's bet on Fed policy over the next two years
- 10Y yield - long-run growth + inflation + term premium
- Spread - when negative, the market expects rate cuts (slowing growth or recession)
Track record
The 10Y-2Y has inverted before every US recession since 1969:
- 1973, 1980, 1981, 1990, 2000, 2007, 2019, 2022
False positives are rare but exist (1966, 1998).
What to read alongside
The 10Y-2Y is one of many curve measures. Pair it with:
- 3M-10Y - Fed's preferred measure
- HY OAS - credit-market confirmation
- ISM new orders - real-economy lead
- Initial claims - labor confirmation
A single spread is a signal. Three confirming signals is a setup.
