CMORG holds sector-wide cloud outage simulation exercise
The Cross-Market Operational Resilience Group (CMORG) yesterday (8 October 2026) completed its biennial simulation exercise, known as SIMEX26, focused this year on a global cloud services disruption. The group – chaired by the Bank of England (the Bank) and UK Finance, with participation from HM Treasury, the Financial Conduct Authority and the wider financial sector – met to undertake a wide-ranging crisis management exercise, with the 38 largest and most systemically important banks and market infrastructure operators involved. The exercise, which was opened by the Economic Secretary to the Treasury and hosted by the London Stock Exchange Group, involved firms working alongside the financial authorities to respond to a scenario focusing on global disruption to cloud-based services.
