Rates volatility quant interview guide covering rate volatility, swaptions, convexity, volatility surface, hedging, and examples.

Candidates discussing swaptions, convexity, and option-like rates exposure.

Rates volatility prices uncertainty in rates

Rates volatility appears in instruments such as swaptions, caps, floors, callable bonds, and mortgages with embedded prepayment optionality.

The underlying is a rate or curve instrument

Rates options often depend on swap rates, forward rates, or curve dynamics. The underlying differs from ordinary equity options.

Concrete example

A payer swaption gives the right to enter a swap paying fixed. Its value depends on rates, volatility, expiry, tenor, and curve assumptions.

Convexity links options and bonds

Instruments with embedded options can have changing duration and convexity as rates move. Hedging requires more than static DV01.

Common mistakes

Candidates often transfer equity-volatility intuition without adjustment. Rates volatility has curve, tenor, and instrument-specific conventions.
