NSE revamps Nifty Bank and Financial Indices to meet SEBI's derivatives norms
The Nifty Bank and Nifty Financial Services indices will see revised weightage rules that sharply restrict concentration among the top three constituents. Their weights will now be capped at 19%, 14% and 10% respectively, while non-F&O stocks will face a 4.5% individual cap and a 10% cumulative ceiling. The Nifty Financial Services index will implement these changes in a single tranche on the last trading day of December 2025, while the Nifty Bank index will absorb the adjustments in four stages from December 2025 through March 2026.
