Yield curve

To interpret a yield curve, keep currency, credit quality and other material terms comparable. An upward-sloping curve shows higher yields at longer maturities; an inverted curve shows the reverse. Expectations about future short rates, term or liquidity premiums and supply-and-demand conditions can influence its shape. A curve is not a guaranteed forecast. Distinguish spot rates for individual maturities from yields to maturity on coupon bonds. Corporate debt often trades at a spread over an appropriate government or benchmark curve because of credit and other differences.

Worked example

Comparable one-, three- and five-year instruments yield 3%, 3.6% and 4.1%. The curve is upward sloping. It does not follow that the one-year rate must be exactly 4.1% in four years, because longer yields may include premiums and other influences.

Common mistake

Comparing debt with different currencies or credit risks and attributing the entire yield difference to maturity.
