What Is a Yield Curve?
A yield curve is a graph that plots interest rates or yields of similar fixed-income instruments with differing maturities across time. The curve creates a visual representation of the term structure of interest rates. By aggregating lender priorities over time for a particular borrower or credit risk profile, yield curves enable you to study financial market conditions and analyze potential investments or trading opportunities.
Yield curves are borrower-specific, so different curves are constructed for sovereign debt (e.g., the US Treasury default-free curve), the interbank markets (the swap curve), and corporate debt (a credit spread over the swap curve).
They are typically constructed and calibrated to the market prices of a variety of fixed-income instruments, including government debt, money market rates, short-term interest rate futures, and interest rate swaps. To build a smooth and consistent curve, you use a combination of bootstrapping, curve fitting, and interpolation techniques. These curves, once constructed, can then be used to price other OTC derivatives consistently with the markets.
