2s10s Spread: Yield Curve Recession Signal Explained
By Ken Chigbo, Founder, KenMacro. Published 2026-05-13.
Quick answer
The 2s10s spread is the yield on the 10 year US Treasury note minus the yield on the 2 year US Treasury note. It is the most watched slope of the US yield curve. When the spread turns negative, the curve is inverted, a condition that has preceded every US recession since the 1970s.
What is 2s10s spread?
The 2s10s spread measures the difference between the 10 year and 2 year US Treasury yields, expressed in basis points. It is a headline gauge of the Treasury curve’s slope. A positive reading means longer dated debt yields more than shorter dated debt, which is the historical norm and reflects term premium plus expected future policy rates. A negative reading, known as an inversion, means investors accept a lower yield to lock in duration, typically because they expect the Federal Reserve to cut rates in response to slowing growth. The spread is quoted continuously and updated tick by tick alongside cash Treasury markets.
How traders use 2s10s spread
Macro desks track the 2s10s spread as a regime indicator rather than a short term timing tool. Retail traders watch it through the FRED series T10Y2Y or via terminal tickers. A steepening trend, where the spread widens, often coincides with risk on conditions, a weaker US dollar against high beta currencies, and outperformance of cyclicals. A flattening or inverting trend signals tightening policy expectations and tends to support the dollar against commodity currencies while pressuring bank equities. Institutional desks express views through curve trades, buying 2 year futures against selling 10 year futures, or the reverse, sized in DV01 neutral ratios. The desk treats the initial inversion as a warning, not a sell signal, given the typical lag of twelve to twenty four months before the recession actually begins.

Common misconceptions about the 2s10s spread
First, inversion does not cause a recession, it reflects collective expectations of future rate cuts. Second, the 2s10s is not the only curve that matters. The New York Fed favours the 3 month versus 10 year spread for its recession probability model, and the two can give conflicting signals at turning points. Third, the lag between inversion and recession is variable and has stretched well beyond a year in recent cycles, so using inversion as an equity exit trigger has historically been premature. Fourth, the steepening that follows an inversion, known as bull steepening when driven by front end rallies, is often the cycle’s clearer recession tell.

Frequently asked
What does it mean when the 2s10s spread inverts?
Inversion means the 2 year Treasury yields more than the 10 year. It indicates that bond investors expect the Federal Reserve to cut policy rates in the future, usually because growth and inflation are projected to weaken. Historically every US recession since the late 1970s has been preceded by a 2s10s inversion, though the lead time varies from several months to over two years. Inversion is a signal of expectations, not a mechanical trigger.
Where can I track the 2s10s spread in real time?
The Federal Reserve Bank of St Louis publishes the daily series as T10Y2Y on the FRED database, updated each US business day. Bloomberg and Refinitiv terminals carry live tickers, and TradingView hosts the same FRED feed with a small lag. Most retail brokers do not provide direct cash Treasury yields, so traders typically use FRED, the US Treasury’s daily par yield curve page, or futures based proxies on 2 year and 10 year note contracts.
How is the 2s10s spread different from the 3m10y spread?
The 2s10s uses the 2 year note as the front end anchor, while the 3m10y uses the 3 month Treasury bill. The 3m10y sits closer to the current Fed funds rate and is the spread the New York Fed uses in its official recession probability model. The 2s10s incorporates more forward looking rate expectations because the 2 year yield already prices in anticipated policy moves. The two can invert at different times, with 2s10s typically inverting first.
Does an inverted 2s10s spread affect forex markets?
Yes, indirectly. A flattening or inverting US curve usually reflects tighter Fed policy relative to growth expectations, which tends to support the US dollar against pro cyclical currencies such as the Australian and New Zealand dollars. Conversely, a sharp bull steepening, driven by aggressive cuts being priced into the 2 year, often coincides with dollar weakness against the yen and Swiss franc as safe haven flows rotate. The desk treats curve shape as one input among several rather than a standalone signal.
