What does an inverted yield curve mean?

A positive spread (long-term yields above short-term) is normal and healthy. A negative spread — an inverted yield curve — has preceded every US recession since the 1970s and is the classic warning sign.

How long after inversion does a recession start?

Historically, recession tends to arrive 6 to 24 months after the curve first inverts — and since the 1980s it has often begun only after the curve un-inverts back to positive. The lead time is long and variable, so inversion is a warning, not a countdown clock.

Why can risk stay high after the curve turns positive?

Because recessions often start after the curve steepens again. Some models therefore keep a "very high" recession rating for about six months after un-inversion and fade it out by roughly twelve months. Our page instead shows where the live spread sits versus history; use both views together — the chart for level, the cycle for timing.

When was the yield curve last inverted?

The 10y–2y spread inverted in mid-2022 and stayed negative into 2024, one of the longest inversions on record, before turning positive again.

The Yield curve (10y–2y) is 0.40pp as of September 2, 2026. The gap between 10-year and 2-year yields is thin — a flatter curve than usual, often seen when markets expect slower growth.

Historical crashes marked on this chart (4)

The dashed red lines flag major US market crashes within this indicator’s history. Here is what happened at each and what followed.

Black Monday (1987): On October 19, 1987 the Dow fell 22.6% in a single day — the worst one-day drop in history — driven partly by program trading. The economy avoided recession and markets recovered within two years.
Dot-com crash (2000): The tech bubble burst in March 2000; the Nasdaq lost about 78% by 2002 as internet valuations collapsed. A mild recession followed and tech stocks took roughly 15 years to reclaim their peak.
Global Financial Crisis (2008): The subprime mortgage meltdown and Lehman Brothers' collapse cut the S&P 500 about 57% into March 2009. It triggered the Great Recession, sweeping bailouts, and a decade of near-zero interest rates.
COVID crash (2020): Pandemic lockdowns caused the fastest bear market ever in February–March 2020, a roughly 34% plunge in weeks. Unprecedented Fed and fiscal stimulus sparked a rapid recovery to new highs.

The gray line is the trend baseline; the ±2σ bands are the standard deviation bands used to assign the verdict. This gauge is inverted: a low reading can still signal overvaluation.

Overview

The 10-year minus 2-year Treasury yield spread is a widely watched recession lead indicator. It measures the gap between intermediate and shorter-term US government borrowing costs. Normally the 10-year yield is higher, giving a positive spread; when the curve inverts and the spread goes negative, a recession has historically followed — usually 6 to 24 months later, and often after the curve un-inverts rather than during the inversion itself. We also track the traditional 10-year minus 3-month spread used by the New York Fed.

How to read it

A positive spread is the normal state: investors earn more for lending longer. When the spread turns negative (the curve inverts), short-term yields exceed longer-term ones — markets are pricing rate cuts and slower growth. Deep or sustained inversions are the warning. Important nuance: the recession often arrives after the spread has already turned positive again, so a "normal-looking" reading right after a long inversion is not an all-clear. Our verdict is a z-score of today's level (inverted so low = more stressed); combine it with where you are in that inversion → un-inversion cycle.

The inversion cycle vs. today’s z-score

Think of the yield curve as a two-act play, not a single reading. Act one is inversion: short-term yields rise above longer-term yields. That has preceded every US recession since the 1970s. Act two is un-inversion: the spread turns positive again, usually because the Fed is cutting (or expected to cut) short-term rates. Since about 1980, the official recession often starts in that second act — months after the curve looks "healthy" again.

Our headline verdict answers a different question: where does today's spread sit relative to its own history? A deeply negative reading scores as elevated risk; a spread back near its long-run average scores as calmer. That is useful for comparing this gauge to CAPE, the VIX, and the rest of the composite — but it can understate risk in the months right after un-inversion, when the level looks fine and the cycle history still says caution.

A practical reading checklist: (1) Is the spread below zero now? That is the classic warning. (2) If it recently crossed back above zero after a sustained inversion, treat the next roughly 6–12 months as still elevated recession risk even if our z-score softens. (3) Very wide positive spreads (far above the historical mean) have often appeared after the Fed has already slashed rates into a downturn — closer to a recovery/buying backdrop than a late-cycle peak.

How it's calculated

This indicator is judged against a flat historical mean. The current reading is expressed as a z-score — standard deviations from that baseline.

The spread is published daily by the Federal Reserve as the difference between the 10-year and 2-year Treasury constant-maturity yields (FRED T10Y2Y).
We store the daily value in percentage points and judge it against its flat historical mean with standard-deviation bands.
Because a low (flat or negative) spread is the warning, the verdict is inverted: unusually low readings register as elevated recession / stress risk.
We do not auto-extend a "very high" label for a fixed number of months after un-inversion; that cycle context is explained in the reading notes below the chart so the composite stays comparable across indicators.

Criticisms

The lead time between inversion and recession is long and variable — sometimes under a year, sometimes closer to two.
A positive spread after a long inversion can look "normal" on a z-score chart even while the historical recession window is still open.
It is a recession signal, not a direct measure of stock valuation, and it says nothing about how severe a downturn will be.
