Credit Spread Quant Interview Guide
Credit spread quant interview guide for spread definition, default risk, liquidity, duration, curves, examples, and caveats.
Candidates discussing corporate bonds, default risk, and relative value.
Credit spread compensates for more than default
A credit spread reflects default risk, recovery uncertainty, liquidity, taxes, risk premia, technicals, and the benchmark curve being used.
Spread duration matters
A long-duration credit bond can be more sensitive to spread changes than a short-duration bond with the same spread level.
Concrete example
If a corporate bond spread widens by 50 basis points, the price impact depends on spread duration and any simultaneous Treasury rate move.
Separate rates and credit
Corporate bond returns can be driven by risk-free rate moves and credit spread moves. A clean answer separates those sources.
Common mistakes
Candidates often interpret spread as pure default probability. Recovery, liquidity, risk premia, and market structure also affect spreads.
