The Inverted Yield Curve: 7-of-7 Recession Track Record

The inverted yield curve is the most reliable single recession indicator in the modern US business-cycle toolkit. When the 10-year Treasury yield falls below the 2-year Treasury yield (or below the 3-month Treasury bill yield in the alternative version), the curve is inverted, and recession has followed every time the inversion has occurred since 1969. The average lead time from the start of inversion to the recession beginning has been approximately 18 months. The only false signal in the post-1969 period was a brief 1998 inversion during the Russian financial crisis that did not produce a recession within the historical lead-time window (the 2001 recession came three years later, after the 1998 inversion had long since ended).

As of April 2026, the 10Y-2Y spread is positive at approximately +21 basis points, having re-steepened from inversion in late 2025 and early 2026. The 2022-25 inversion lasted 42 months, the longest in the modern monitoring period without producing a recession within the historical lead-time window. The question of whether the post-2025 re-steepening will be followed by a recession within the typical 6-12 month un-inversion-to-recession window is now the live recession-monitoring question of 2026. The Federal Reserve Bank of New York's yield-curve recession-probability model currently puts the 12-month-ahead probability at approximately 28 percent.

What the Yield Curve Measures

The Treasury yield curve plots yields on US Treasury securities against their time to maturity, from 1-month and 3-month bills at the short end through 2-year and 10-year notes to 30-year bonds at the long end. Under normal conditions, the curve slopes upward: longer-dated securities offer higher yields than shorter-dated ones, because investors demand additional compensation for the longer time horizon. The premium reflects the increased uncertainty about future inflation (a 10-year inflation forecast is less reliable than a 3-month forecast), the increased uncertainty about future Fed policy (which directly drives short-end yields), the reinvestment-risk associated with reinvesting cash flows over a longer period, and the credit-risk associated with longer-dated US government obligations (very low for Treasuries but not zero).

When the curve inverts, short-term yields exceed long-term yields. The 10-year Treasury yields less than the 2-year. This is unusual because it implies that bond-market participants are willing to lock in a longer-dated lower yield rather than continuously roll over higher-yielding short-dated holdings. The behaviour is rational only if those participants expect short-term yields to fall in the future, which historically reflects expectations that the Federal Reserve will cut the federal funds rate (the primary driver of 2-year yields) in response to weakening economic conditions or recession.

The Two Variants: 10Y-2Y and 10Y-3M

Two specific yield-spread variants are most commonly tracked. The 10-year minus 2-year (10Y-2Y) spread, published as FRED series T10Y2Y, is the most widely cited in financial-media coverage. The 10-year minus 3-month (10Y-3M) spread, published as FRED series T10Y3M, is preferred in academic research on recession prediction, particularly the work of Arturo Estrella and Frederic Mishkin at the Federal Reserve Bank of New York through the 1990s.

The 10Y-3M variant is generally considered the cleaner technical measure because the 3-month bill more directly reflects the current federal funds rate, while the 2-year Treasury reflects an average of expected Fed policy over the next 24 months. The 10Y-3M spread therefore captures the gap between the long-end (growth and inflation expectations) and the immediate Fed policy stance more directly. The 10Y-2Y variant has more historical data available (the 2-year Treasury series begins in 1976; the bond-equivalent 3-month bill series goes back earlier) and is more familiar to retail investors and financial media.

Both variants have similar historical track records: both inverted before every postwar US recession since 1969, with similar lead times. The 10Y-3M variant tends to invert slightly later in the cycle (because the 3-month bill responds more sluggishly to Fed expectations than the 2-year), and the 10Y-2Y variant tends to invert slightly earlier. Either variant captures the underlying signal.

The Seven-of-Seven Track Record

The historical record of yield-curve inversions preceding US recessions is exceptionally consistent. The 1969-70 recession was preceded by an inversion that began in December 1968. The 1973-75 recession was preceded by an inversion beginning in June 1973. The 1980 recession was preceded by an inversion beginning in October 1978. The 1981-82 recession was preceded by an inversion beginning in October 1980 (and was preceded by the inversion that had already preceded the 1980 recession, with the curve remaining inverted across the brief 1980-81 expansion).

The 1990-91 recession was preceded by an inversion beginning in December 1988 (more than 18 months before the recession peak, the longest pre-recession inversion until that point). The 2001 recession was preceded by an inversion beginning in February 2000. The 2007-09 Great Recession was preceded by an inversion beginning in July 2006. The 2020 COVID recession was preceded by an inversion beginning in August 2019 (though the COVID recession was driven by a public-health shock rather than by the economic conditions the inversion typically signals; nonetheless, the inversion was present).

The only false signal in the post-1969 period was a brief 1998 inversion during the Russian-LTCM financial crisis. The 10Y-2Y spread inverted briefly in September 1998 before re-steepening as the Fed cut rates aggressively (the funds rate fell from 5.50 percent to 4.75 percent in three rapid cuts). The economy continued expanding for another two and a half years before the 2001 recession began. Even allowing for the 18-month average lead time, the 2001 recession was three years after the 1998 inversion, beyond any reasonable lead-time window. The 1998 false signal is the only clean exception in 55 years of US data.

The Un-Inversion Paradox

An empirical pattern that practitioners have long noticed and that academic research has subsequently formalised: recessions typically begin not when the yield curve inverts but when it un-inverts (re-steepens). In every postwar US recession that the yield curve preceded, the curve had inverted some months earlier, then began re-steepening as bond markets priced in Fed easing in response to weakening conditions, and the recession officially began within 6 to 12 months of the re-steepening.

The mechanism is straightforward. Inversion occurs when the Fed has tightened monetary policy and the bond market expects future easing in response to deteriorating conditions. Re-steepening occurs when the deteriorating conditions become evident enough that the Fed actually begins cutting (causing short-end yields to fall faster than long-end yields). The actual Fed cuts and the deteriorating conditions that prompted them are then closely associated with the official recession start that NBER subsequently dates. The 2-year Treasury yield, which closely tracks expected Fed policy, falls sharply as the cuts arrive. The 10-year Treasury yield falls less sharply because long-run growth and inflation expectations adjust more slowly. The result is a fast re-steepening that historically maps onto the recession start.

The pattern means that the recession-monitoring focus should arguably be on the un-inversion rather than the inversion itself. By the time the curve is re-steepening, the economic deterioration that the inversion forecast is becoming evident. The 6 to 12 months between re-steepening and the official recession start is the period in which leading indicators (Conference Board LEI, ISM PMI), coincident indicators (Sahm rule), and confirming GDP / employment data all begin pointing in the same direction.

The 2022-25 Inversion: Longest Without Recession

The 2022-25 inversion was the longest in the modern monitoring period (since the 10Y-2Y series began in 1976) without producing a recession within the historical lead-time window. The inversion began in July 2022 as the Federal Reserve's aggressive 2022-23 tightening cycle pushed short-end yields up faster than long-end yields. The inversion deepened through 2022 and 2023, reaching a peak inverted spread of approximately negative 100 basis points in mid-2023. The inversion persisted through 2024 and most of 2025 before re-steepening in late 2025 as the Fed began cutting in response to softening labour-market data.

The 42-month inversion duration was unprecedented. Prior to 2022-25, the longest US yield curve inversion had been approximately 24 months in 1980-82 (which corresponded to the Volcker double-dip recessions). The 2022-25 inversion exceeded that by more than 50 percent. Yet no recession was officially dated by NBER during the inversion or in the typical 18-month lead-time window following its start. The 2024 NBER-dating window would have produced a recession declaration if standard patterns had held, but the relevant indicators (GDP, employment, real personal income) did not deteriorate sufficiently to support a recession declaration. The 2025 window remains open, and the 2026 indicator picture will be retrospectively assessable from approximately mid-2026 onward.

Several explanations have been offered for the unusual lag. The COVID-era fiscal and monetary stimulus had built up substantial household and corporate cash balances that buffered economies against tighter monetary conditions for longer than typical. The labour market remained tight throughout the inversion period (unemployment averaged under 4 percent for most of the inversion), suggesting the underlying economy was less interest-rate-sensitive than in prior cycles. The inversion itself was driven heavily by the Fed's tightening response to inflation rather than by deteriorating long-run growth expectations, which may have produced a less reliable recession signal than inversions driven by long-end yield declines. Whichever explanation is most accurate, the 2022-25 inversion is now an important data point in any future application of yield-curve recession indicators.

The 2026 Re-Steepening Question

The re-steepening began in late 2025 as the Federal Reserve started cutting the federal funds rate in response to the rising Sahm rule reading and softening labour-market data. The 2-year Treasury yield fell faster than the 10-year Treasury yield (the standard pattern), and the 10Y-2Y spread crossed back into positive territory in January 2026. As of April 2026, the spread sits at approximately +21 basis points.

The historical pattern would suggest a recession should follow within 6 to 12 months of the re-steepening, putting the recession-onset window roughly between July 2026 and January 2027. The New York Fed recession-probability model puts the 12-month-ahead probability at approximately 28 percent. The Bloomberg economist consensus survey puts it at 35 percent. Both numbers are elevated above historical norms but well below the 70-80 percent readings that have characterised the months immediately preceding actual recession starts.

Whether the 2022-25 inversion eventually produces a recession (consistent with the 7-of-7 historical pattern) or becomes the first clean false signal in the 1976-present period is the live recession-monitoring question. The other indicators (Sahm rule, ISM PMI, jobless claims, LEI, consumer confidence) will provide confirming or refuting evidence over the coming months. If a recession is declared in late 2026 or 2027, the yield curve will have produced an unusually long lead-time signal. If no recession occurs, the 2022-25 inversion will be the most significant false signal in the modern record.
