UK Treasury designates Google Cloud as a critical third party to the financial sector, placing it under direct Bank of England, PRA, and FCA oversight
Google Cloud EMEA was designated a critical third party (CTP) to the UK financial sector by HM Treasury on 10 July, bringing it under direct supervisory oversight by the Bank of England, the Prudential Regulation Authority (PRA), and the Financial Conduct Authority (FCA). The designation reflects the materiality of Google Cloud's services to UK financial institutions and triggers a deeper regulatory collaboration between the tech company and the three supervisory bodies. The CTP regime was introduced to address the systemic risk that arises when a significant portion of the financial sector depends on a single third-party technology provider: a failure or severe disruption to that provider could cascade across multiple regulated firms simultaneously. Google Cloud was one of the first four providers designated under the regime, alongside Amazon Web Services, Microsoft, and Oracle, given the breadth of financial sector clients relying on their cloud infrastructure for core operations including data processing, settlement systems, and risk management platforms.
Why this matters
Designating a major cloud provider as a CTP is a structural step in the UK's operational resilience framework, moving beyond firm-level requirements to address the concentration risk that sits above individual institutions. For Google Cloud, CTP status means accepting direct regulatory engagement, producing resilience self-assessments, and potentially being subject to skilled persons reviews coordinated by the supervisors. The practical effect is that Google Cloud's contractual and operational arrangements with UK financial institution clients now sit within a regulatory perimeter, not just a commercial one. The Treasury designated Amazon Web Services, Microsoft and Oracle at the same time, so the regime is addressing concentration risk across the major providers at once rather than one at a time.
On the Ground
The CTP designation activates financial regulation, outsourcing, technology contracting, and operational resilience practices across the City. Law firms advising UK banks and insurers will need to review third-party risk management frameworks and update contractual arrangements with Google Cloud to reflect CTP-status obligations. Regulated firms must map their material dependencies on the designated provider and ensure their own operational resilience plans account for CTP-specific scenarios. A trainee on a related matter would assist with regulatory notification drafting, licence condition summaries reflecting the new CTP framework, and compliance gap analysis memos comparing existing outsourcing agreements against the updated supervisory expectations.
