Guest Contribution: “Does the Yield Curve Still Predict Recessions? U.S. and OECD Evidence”

Key Takeaways

• Yield curve still predicts recessions, but signals weaker post‑2022.
• Debt service ratio boosts forecast accuracy in five of eight OECD nations.
• United States and UK see highest probability spikes for 2024 recessions.
• France, Germany, Japan forecast performance declines when debt service ratio added.
• Probit models evaluated with Brier scores beat neutral 0.5 benchmark.

Pulse Analysis

The yield curve has long been a go‑to barometer for looming recessions, with an inverted spread between long‑ and short‑term rates historically preceding downturns in the United States and Europe. Yet the 2022 inversions across major economies failed to trigger immediate recessions, prompting scholars to question the indicator’s relevance. Chen’s study revisits this debate by assembling a comprehensive monthly dataset spanning three decades, allowing a fresh look at how the curve’s predictive power has evolved in a low‑interest‑rate era.

Using probit models that forecast recession risk twelve months ahead, the research contrasts three specifications: a pure yield‑spread model, one that adds the short‑term rate, and a third that incorporates the debt service ratio (DSR), a measure of household and corporate debt burdens. The DSR improves forecast accuracy in five of the eight countries examined—most notably the United States and the United Kingdom—by capturing financial vulnerabilities that the spread alone misses. Conversely, the ratio degrades performance in France, Germany and Japan, underscoring that debt dynamics interact with local macro‑financial conditions in heterogeneous ways. Model performance is gauged with Brier scores, which consistently beat the neutral 0.5 benchmark, confirming that even imperfect signals retain informational value.

For policymakers and market participants, the study signals that the yield curve should not be discarded but rather complemented with debt‑related metrics to sharpen recession forecasts. As central banks navigate prolonged low rates and elevated debt levels, integrating the DSR could enhance early‑warning systems and inform tighter or more accommodative policy moves. Future research will need to unpack the channels through which debt burdens amplify or dampen recession risk, offering a richer toolkit for navigating an increasingly complex financial landscape.
