The US Treasury yield curve, measured by the spread between the 10-year and 2-year yields, has returned to positive territory after the longest sustained inversion in modern history. While many interpret this as an all-clear signal, historical precedent suggests the opposite: recessions have typically begun after the curve un-inverts, not during the inversion itself.
The Record-Breaking Inversion
The 10Y-2Y spread first turned negative in July 2022 and remained inverted for over two years — surpassing the previous record set in the late 1970s. At its deepest point in July 2023, the spread reached approximately -108 basis points, the most extreme inversion since the early 1980s.
This prolonged inversion reflected the Federal Reserve's aggressive tightening cycle, which pushed short-term rates above 5% while longer-term yields were anchored by expectations of eventual rate cuts and slowing growth.
Why Un-Inversion Matters More Than Inversion
The yield curve's predictive power for recessions is well-documented, but the timing mechanism is often misunderstood. The inversion itself signals that markets expect the Fed will eventually need to cut rates — typically in response to economic weakness. The un-inversion usually occurs when that weakness begins to materialize:
- 1990: The curve un-inverted in early 1990. The recession began in July 1990.
- 2001: The curve un-inverted in late 2000. The recession began in March 2001.
- 2007: The curve un-inverted in mid-2007. The recession began in December 2007.
- 2020: The brief 2019 inversion preceded the COVID-induced recession.
In each case, the lag between un-inversion and recession onset ranged from a few months to roughly a year.
Current Economic Signals
Several indicators warrant attention as the curve normalizes:
Labor market cooling: The unemployment rate has drifted higher from its 3.4% cycle low, though it remains historically low. Initial jobless claims have shown a gradual upward trend.
Credit conditions: Bank lending standards have tightened significantly, and commercial real estate continues to face refinancing pressures. Corporate credit spreads, while not at distressed levels, have widened from their 2024 tights.
Consumer resilience vs. exhaustion: Consumer spending has remained surprisingly robust, but rising delinquency rates on credit cards and auto loans suggest the lower-income consumer is under increasing strain.
Manufacturing divergence: The ISM Manufacturing PMI has oscillated around the 50 expansion/contraction threshold, while services have remained in expansion territory — a pattern reminiscent of previous late-cycle dynamics.
What AI Models Suggest
Our ensemble of machine learning models, trained on yield curve dynamics, credit spreads, labor market indicators, and sentiment data, currently assigns a 35% probability of recession within the next 12 months. This is elevated relative to the unconditional baseline of roughly 15%, but well below the 60%+ readings that preceded the 2001 and 2008 recessions.
The models highlight an important nuance: the current cycle has been unusual in many respects — the post-pandemic inflation surge, the speed of the tightening cycle, and the resilience of labor markets all represent deviations from historical patterns. This reduces confidence in purely backward-looking statistical models.
Conclusion
The yield curve's return to positive territory should not be interpreted as a signal that recession risk has passed. If anything, history suggests the risk may be entering its most acute phase. Investors and policymakers should monitor the labor market, credit conditions, and leading indicators closely in the months ahead. The yield curve has done its job as an early warning system — the question now is whether the economy can achieve the elusive soft landing.
