CS01
CS01 estimates the change in a credit instrument's value for a one-basis-point change in credit spread, usually holding other model inputs constant.

How CS01 works
Credit pricing translates expected default, recovery, liquidity and risk compensation into spreads and market values. The same issuer can therefore trade differently across maturities, seniorities and instruments even when the underlying operating business is unchanged. CS01 is most useful when compared across similar maturities, seniorities and market regimes. Market prices can embed liquidity, technical positioning and risk appetite in addition to expected default and recovery.
Why it matters to credit investors
CS01 matters because credit markets price both the probability of stress and the expected loss if stress occurs. It helps separate operating performance from capital-structure, liquidity and market-technical effects.
What to look at
Watch issuer fundamentals, leverage, liquidity, maturity concentration, spread levels, market volatility and assumptions about default and recovery.
