UK Regulators to Begin Overseeing Critical Third Parties to the Finance Sector

UK financial regulators are preparing to begin oversight of so-called critical third parties, following their designation by the Treasury, in a significant expansion of supervision aimed at reducing systemic risk from shared technology dependencies. Banks, insurers and other financial firms increasingly rely on a small number of external providers, particularly large cloud computing and technology companies, for services essential to their day-to-day operations. A serious outage or cyberattack at one of these providers could disrupt many firms at once, threatening payments, trading and customer access across the system. Under the new framework, the Bank of England, Prudential Regulation Authority and Financial Conduct Authority will be able to set resilience standards for the designated providers and test their ability to prevent, withstand and recover from disruption. Crucially, the providers themselves, not just the financial firms that use them, will fall within scope, closing a gap that previously left regulators reliant on individual firms to manage concentration risk. The approach mirrors moves in other major jurisdictions grappling with the same dependencies. For the financial sector, the regime is intended to bolster continuity of critical services, while providers face new obligations to demonstrate robust security, resilience and recovery capabilities to supervisors.
