Vasicek Model Adaptation

Model

The Vasicek model, a foundational interest rate model, posits that short-term interest rates follow an Ornstein-Uhlenbeck process, characterized by mean reversion. Initially developed for modeling government bond yields, its simplicity and analytical tractability have fostered widespread adoption. Within cryptocurrency derivatives, adaptations of the Vasicek model are increasingly employed to price options on perpetual futures and other interest-rate-like instruments, particularly where a stablecoin or algorithmic stablecoin serves as the underlying asset. These adaptations require careful calibration to reflect the unique dynamics of crypto markets, including volatility and liquidity.
