The yield curve and 2s10s: inversion and steepening, explained

Last updated: 2026-10-07

The yield curve plots what a government pays to borrow at each maturity, from a few months out to thirty years. Its usual shorthand is 2s10s: the 10-year Treasury yield minus the 2-year, in percentage points. Positive means the curve slopes up, as it usually does; negative means it is inverted.

It earns its place in a macro view because the two ends answer different questions, so the gap between them is the bond market's own summary of where policy and growth are heading.

What each end prices

The 2-year yield tracks where the market expects the central bank's policy rate to be over the next two years. It moves on inflation prints, payrolls and every word from the Fed.

The 10-year yield is the expected path of short rates over a decade plus a term premium: the extra compensation for locking money up through whatever inflation and government borrowing the decade brings. Because that premium is normally positive, a healthy curve slopes upward.

2s10s = 10Y yield − 2Y yield

  > 0   normal: long money costs more than short
  ≈ 0   flat: the market sees policy near where it will stay
  < 0   inverted: policy is priced as tight now and lower later

What an inversion says

When the 2-year yields more than the 10-year, the market is saying that policy is restrictive today and will have to ease, which usually means it expects growth to weaken. That is why the curve has a reputation: inversions have come before most US recessions of the past half-century.

Two caveats come with that reputation. The lead time has ranged from a few months to around two years, so an inversion moves the odds, not the date. And not every inversion has been followed by a recession. It is a statement about expectations, and expectations can be wrong.

Steepeners and flatteners

The same change in 2s10s can come from either end, and the end that moved is the story. Bond traders name the four cases:

MoveWhat happensWhat it usually reads as
Bull steepenerShort yields fall faster than long ones.The market is pricing rate cuts, often as growth softens.
Bear steepenerLong yields rise faster than short ones.Inflation worry, a rising term premium or heavy government borrowing.
Bear flattenerShort yields rise faster than long ones.The market is pricing hikes: policy getting tighter.
Bull flattenerLong yields fall faster than short ones.Growth fears and a flight into long-dated bonds.

Reading it in practice

  1. Ask which end moved. A curve steepening because the 2-year fell on rate-cut hopes is a different market from one steepening because the 10-year jumped on inflation fear.
  2. Watch the exit from an inversion. The re-steepening has often arrived late in the cycle, as the market starts pricing cuts in earnest, which is why it is not the all-clear it looks like.
  3. Check it against credit. A curve warning that the credit spreads don't confirm is a forecast; one they confirm is already happening.
  4. Know which spread you are reading. The New York Fed's recession-probability model uses the 10-year minus the 3-month bill rather than 2s10s. The two usually agree on direction and can disagree on timing. MacroView carries 2s10s.

Where to see it live

The Macro Lens shows 2s10s with its recent trend beside the policy rate, inflation and payrolls. The Bonds view shows the 2-year, the 10-year and 2s10s next to the bond funds they move. All three come from FRED's daily series (DGS2, DGS10), with 2s10s taken on the latest date both have printed. AI agents read the same numbers through the get_macro_snapshot MCP tool (twoY, tenY, twos10s); see MacroView for AI agents.
