Jarrow-Turnbull Model

Algorithm

The Jarrow-Turnbull Model, initially conceived for fixed income securities, provides a framework for pricing contingent claims under a jump-diffusion process, acknowledging discrete shifts in asset prices alongside continuous Brownian motion. Its application to cryptocurrency derivatives necessitates careful calibration of jump parameters to reflect the heightened volatility and infrequent, yet substantial, price movements characteristic of digital assets. Adapting the model requires consideration of the unique market microstructure of crypto exchanges, including order book dynamics and the potential for manipulation, influencing the accurate estimation of jump intensity and size. Consequently, the model’s utility extends to risk management, enabling the calculation of Value-at-Risk and Expected Shortfall for portfolios exposed to crypto options and futures.
