The Securities and Exchange Board of India introduced an IT Resilience Index, called ITRI, for market infrastructure institutions such as stock exchanges, clearing corporations and depositories. The framework measures the robustness of critical IT systems on a 100 point scale across nine parameters, with availability and security carrying the highest weight at 20 points each, followed by integrity, governance, reliability and monitoring, business continuity, and modularity and flexibility at 10 points each, and scalability and incident handling at 5 points each. Market infrastructure institutions must develop an early warning system to detect possible deterioration in any parameter, and will compute the index on a half yearly basis, with the first computation covering the half year ending 31 March 2027, submitting a comparative analysis and corrective actions to their governing boards.
