The yield curve shows the interest rates investors demand to hold government bonds with different maturities.
Normally, longer-term bonds offer higher yields. When short-term yields rise above long-term yields, the curve becomes inverted — a pattern historically associated with weaker economic growth and recession risk.
How the yield curve works
One of the most watched measures compares the 10-year Treasury yield with the 2-year yield.
If the 10-year yields 4.5% and the 2-year yields 4%, the spread is positive. If the 2-year rises above the 10-year, the curve is inverted.
Investors can track the historical 2s10s spread through the Federal Reserve Bank of St. Louis. The spread remained inverted from 2022 into 2024 before turning positive again.
Why inversion matters
An inversion often appears after the Federal Reserve raises short-term rates to fight inflation while investors expect weaker growth and lower rates later.
Demand for longer-term bonds can then push their yields below short-term rates.
Federal Reserve research has found the yield curve useful as a recession indicator, although it works best alongside other economic data.
An inversion does not mean a recession is immediate. The delay can last months, and unusual monetary-policy conditions can weaken the signal.
What investors should watch next
The curve can also send important signals when it steepens again.
That can happen because investors expect Fed rate cuts, or because long-term yields rise on inflation, government borrowing or fiscal concerns.
Recent Treasury yields have been affected by heavy US borrowing and inflation concerns. Higher long-term yields have also pressured the stock market, especially rate-sensitive technology shares.
For investors, the yield curve is best used as part of a broader market dashboard rather than a standalone trading signal. Inflation, employment, credit conditions and Fed policy all matter alongside bond yields.
The key point is simple: an inverted curve suggests markets expect today’s high short-term rates to eventually fall, often because economic growth is expected to weaken.
