What is a credit spread?
A credit spread is the difference in yield between a corporate (or other non-government) bond and a treasury bond of similar maturity. It represents the extra compensation investors demand for taking on additional credit (default) risk.
The formula
Credit Spread = Corporate Bond Yield – Treasury Yield. Spreads are usually expressed in basis points (bps), where 1% equals 100 basis points. Wider spreads generally signal higher perceived credit risk or lower liquidity.
