Option-Adjusted Spread

Calculation

The option-adjusted spread represents the yield differential between a fixed-income instrument or crypto-backed structured product and the spot curve, accounting for the value of embedded optionality. Analysts derive this figure by stripping the price effect of call or put features from the nominal spread using a stochastic model. This process isolates the credit risk and liquidity premium, providing a cleaned metric for comparing instruments with heterogeneous maturity profiles or exercise conditions.
