Stress testing enhancements for equity derivatives mandate Stressed VaR, filtered historic simulation and factor-model based MRC determinations. The circular adds three stress-testing methodologies-Stressed VaR (stress-period variance-covariance matrix, doubled volatility, Monte Carlo, 100% option volatility shock), Filtered Historic Simulation (EWMA =0.94 rescaling of historical returns), and a Factor Model (largest three-day NIFTY moves since 2000 scaled by stock beta with 100% option volatility shock)-to determine the MRC of the Core SGF for equity derivatives, mandates a 3-day SPOR, permits a conditional one-time inter-segment transfer of excess ECM funds and penalties to EDX, sets timelines for initial additional contributions and staggered ongoing contributions, and requires CCs to implement SOPs and disclosure and to categorize CCs for exposure modelling.
