Introduction

The yield curve condenses market pricing across maturities into one picture. Its level, slope and changes can reveal information about monetary policy, growth, inflation and risk premia.

What Is the Yield Curve?

The yield curve shows yields on debt securities across different maturities at a point in time. Analysts commonly focus on government bonds because they provide a relatively clean view of the term structure of interest rates.

A curve may be constructed from bills, notes, bonds, swaps or zero-coupon rates depending on the analytical purpose.

The Normal Yield Curve

A normal or upward-sloping curve has higher yields at longer maturities. Investors may demand additional compensation for locking capital away for longer, and the curve can also reflect expectations for future short-term rates and term premia.

An upward slope is common, but it is not a permanent state.

Flat and Inverted Curves

A flat curve occurs when yields across maturities are similar. An inverted curve occurs when short-term yields exceed longer-term yields.

Inversions often emerge when monetary policy is restrictive and markets expect future short-term rates to decline. Historically, some curve inversions have preceded recessions, but the signal is not deterministic and should not be used in isolation.

Common Yield Curve Spreads

Analysts frequently monitor differences such as 10-year minus 2-year yields (2s10s) or 10-year minus 3-month yields. A positive spread indicates the longer maturity yields more; a negative spread indicates inversion.

Different spreads answer different questions, and results can vary depending on the selected instruments and curve construction.

Steepening and Flattening

A steepener means the yield difference between longer and shorter maturities increases. A flattener means the difference decreases. These moves can occur because the front end, long end or both move.

For example, a bull steepener usually involves falling yields with short-term yields falling faster, while a bear steepener usually involves rising yields with long-term yields rising faster.

What the Curve Can Signal

The curve contains information about monetary-policy expectations, inflation expectations, growth perceptions, risk premia and demand for duration. It is therefore central to macro and cross-asset analysis.

However, central-bank balance sheets, regulation, pension demand and global capital flows can distort simple historical interpretations.

Key Takeaways

The yield curve is not just a recession indicator. Its level, slope and changes provide a compact summary of how the market prices rates across time. The most useful analysis separates curve shape from the forces driving the move.
