Bootstrapping Yield Curve Interview Guide
Bootstrapping yield curve interview guide for instruments, discount factors, par rates, interpolation, consistency, and examples.
Candidates learning how market instruments imply discount curves.
Bootstrapping solves the curve sequentially
Curve bootstrapping uses liquid market instruments to infer discount factors or zero rates one maturity at a time from observable prices.
Instrument conventions drive the math
Deposits, futures, bonds, and swaps have different cash-flow and day-count conventions. Those conventions determine the equations being solved.
Concrete example
A one-year zero-coupon bond gives a one-year discount factor directly, while a coupon bond requires earlier discount factors to solve the next point.
Interpolation fills gaps
Market instruments exist only at certain maturities. Interpolation choices can change forwards and risk estimates between those points.
Common mistakes
Candidates often describe bootstrapping as fitting a smooth curve only. The key idea is matching instrument prices through cash-flow equations.
