Yield Curve

The yield curve is a graphical representation of the interest rates (yields) that investors receive for bonds of equal credit quality but varying maturity dates. It plots bond yields on the vertical axis against time to maturity on the horizontal axis, typically showing short‑term Treasury bills on the left and long‑term Treasury bonds on the right. Economists and market participants use the shape of the curve to gauge expectations about future economic growth, inflation, and monetary policy.

How It Works

To construct a yield curve, analysts collect current yields for a series of government securities — such as 3‑month, 2‑year, 5‑year, 10‑year, and 30‑year Treasuries. Each point on the graph corresponds to a specific maturity. Connecting these points produces a line that can slope upward, flatten, or invert.

• Normal (upward‑sloping) curve: Longer maturities carry higher yields, reflecting compensation for greater risk and expected inflation.
• Flat curve: Yields are similar across maturities, often signalling uncertainty about future interest rates.
• Inverted curve: Short‑term yields exceed long‑term yields, historically a precursor to economic slowdown or recession.

The curve can shift daily as market forces — supply and demand for bonds, central bank policy, and inflation expectations — adjust.

Why It Matters

The yield curve serves as a leading indicator for economic activity. A steepening curve often predicts stronger growth, while an inverted curve has preceded every U.S. recession since the 1960s. Investors use it to price bonds, manage portfolio duration, and anticipate changes in borrowing costs. For example, if the 10‑year Treasury yield falls below the 2‑year yield, banks may tighten lending because short‑term funding becomes more expensive than long‑term returns, potentially slowing credit expansion and economic activity.
