The 2s10s spread is the yield difference between the 10-year and 2-year U.S. Treasury notes, expressed in basis points. It is the most widely cited measure of the yield curve slope and serves as a barometer for economic expectations and monetary policy positioning.
A positive 2s10s spread (the historical norm) indicates an upward-sloping curve. A negative spread means the curve is inverted. The spread fluctuates based on:
The 2s10s spread typically ranges from 0 to +250 bps during normal environments. It has inverted before every U.S. recession since the 1960s. The 2022-2024 cycle saw a sustained inversion, with the spread reaching approximately -108 bps in July 2023.
Market participants reference the 2s10s spread in regime classification: a steepening spread during a rally is a bull steepener, while a flattening spread during a selloff is a bear flattener. The five regime classifications (bull/bear x steep/flat, plus Consolidation) each carry distinct implications for portfolio positioning. See the 30 Yr / 2 Yr regime page for the current classification and historical distribution using the long end of the curve.
Fixed-income analysts treat the 2s10s inversion as a leading indicator, not a coincident one. The historical lead time from inversion onset to recession start has ranged from approximately 6 to 24 months across post-1960 cycles. The 1978 inversion preceded the 1980 recession by roughly 18 months. The 2006 inversion preceded the 2008 recession by about 19 months. The 2022 inversion, which began in April 2022 and deepened to -108 bps by July 2023, had not resolved into recession as of mid-2024, with the lag stretching past 24 months.
The variability in lead time reflects two factors. First, inversion depth matters: deeper inversions with more persistent duration tend to generate stronger recessionary signals, because they imply sustained tight policy relative to long-run growth expectations. Second, the policy response speed compresses or extends the cycle. Aggressive Fed easing after inversion onset shortens the lag by restoring the curve faster and supporting credit markets.
The spread also carries false-positive risk. The most notable example is 1998, when the 2s10s briefly inverted during the Russia/LTCM crisis. The Fed cut rates 75 bps in fall 1998, the curve re-steepened quickly, and no recession followed. That episode illustrates the importance of distinguishing a brief, shallow inversion driven by financial stress from a sustained, deep inversion driven by policy tightness and deteriorating growth fundamentals. A single inversion reading below zero is not actionable on its own.
YCP's regime classification system uses the 2s10s as one of two slope inputs, alongside the 30Y/2Y spread. The algorithm classifies the current environment into one of five regimes (Bull Steepener, Bull Flattener, Bear Steepener, Bear Flattener, or Consolidation) by combining the direction of the level change with the direction of the slope change over a trailing window. You can see the current classification, the historical distribution by regime, and the spread chart with NBER recession shading on the 2s10s spread page and the broader regimes hub.
A negative spread, called an inversion, means the 2-year Treasury yields more than the 10-year. It signals that the market expects the Federal Reserve to cut short-term rates in the future, typically in response to slowing growth. Every U.S. recession since the 1960s has been preceded by a 2s10s inversion, though the lead time has ranged from roughly 6 to 24 months depending on inversion depth and the speed of the subsequent policy response.
Both measure the slope of the yield curve, but they emphasize different parts of the policy cycle. The 3m10y spread anchors the short end at the 3-month bill, which closely tracks the current Fed funds rate. The 2s10s anchors at the 2-year, which prices in expected Fed actions over the next two years. The 3m10y inversion has historically been the more reliable recession signal in academic research. The 2s10s is more widely cited by markets.
The /spreads/2s10s page plots the daily history of the 2-year vs 10-year spread back to 1976, with NBER recession shading. The hub at /spreads shows the current value alongside other commonly tracked slope measures.
