The Yield Curve and Recession-Risk Research

Summary

Yield-curve inversion has historically been associated with elevated US recession risk, but timing varies and the signal is not a standalone forecast.

What the yield curve is

The yield curve plots the yield on US Treasury securities across maturities — from 3 months out to 30 years. In normal times it's upward-sloping: you get paid more for lending longer. When short-term yields exceed long-term yields, the curve is inverted.

Why inversion signals recession

An inverted curve can reflect expectations for slower growth, lower future policy rates, or changing term premia. Historically, commonly watched Treasury-curve inversions have often preceded US recessions, but the lead time varies and the relationship is not a deterministic forecast.

The 10Y-2Y vs 10Y-3M

The linked New York Fed model uses the ten-year minus three-month Treasury yield spread to estimate a probability for a stated future horizon. The ten-year minus two-year spread is a different series. Model probabilities depend on the model and sample and are not certain outcomes; the two spreads need not invert on the same date.

Trading around the curve

The curve is a slow-moving macro indicator. Treat it as one piece of economic context rather than as an intraday timing tool or an automatic instruction to change a portfolio.

Key takeaways

• The yield curve is normally upward-sloping.
• Inversions have historically been associated with elevated recession risk, with timing that varies across cycles.
• The linked NY Fed recession model uses the ten-year minus three-month Treasury yield spread.
• Use the curve as one macro indicator alongside other evidence.

Check your understanding

• Inverted curve = Options: Short < long; Short > long; Flat; Negative yields. Correct answer: Short > long. Why: Short-term exceeds long-term.
• Which spread does the linked NY Fed recession model use? Options: 10Y-2Y; 10Y-3M; 30Y-5Y; 2Y-Fed Funds. Correct answer: 10Y-3M. Why: 10Y-3M used in official model.
• What is the safest interpretation of a yield-curve inversion? Options: It guarantees a recession; It is one historical recession-risk indicator with uncertain timing; It predicts the exact market bottom; It only matters for day traders. Correct answer: It is one historical recession-risk indicator with uncertain timing. Why: Yield-curve inversion is informative context, but it is not a guaranteed or precisely timed forecast.
• The yield curve by itself provides: Options: An exact entry time; A dated description of yields across maturities; Guaranteed equity returns; One required asset allocation. Correct answer: A dated description of yields across maturities. Why: A curve describes relative yields; any forecast requires additional assumptions and remains uncertain.
