VEDL Demerger Cross Margin Adjustments Effective April 29
Summary
NSE Clearing Limited has issued adjustments to cross margin weightages effective April 29, 2026, due to the demerger of Vedanta Limited (VEDL). VEDL will be excluded from cross margin computation at end of day on April 29, 2026, and revised weightages based on the April 30, 2026 closing price will be published and made applicable from May 5, 2026. Additionally, spread margins for portfolios containing NIFTYNXT50 Index constituents will increase from 25% to 30% from April 29 through May 4, 2026 end of day. Members are required to sync their portfolios according to revised weightages by May 4, 2026 end of day.
Members holding NIFTYNXT50 Index constituents should note that the temporary spread margin increase from 25% to 30% creates additional margin requirements during the transition period ending May 4, 2026. Firms with concentrated positions in these constituents should pre-fund potential margin shortfalls before the April 29 effective date.
