This document provides detailed descriptions of the response groups and committees that form the operational structure of the Sector Response Framework (SRF). It outlines the roles, responsibilities, membership criteria, invocation triggers, and interdependencies of each group, including the Cross Market Business Continuity Group (CMBCG), UK Finance committees, cyber coordination bodies, financial market infrastructures (FMIs), and international and information-sharing groups. The document supports coordinated sector-wide responses to systemic incidents by clarifying how each group contributes to information sharing, decision-making, and operational resilience.
