The UK-US Data Bridge, which entered into force on 12 October 2023 following the European Commission’s earlier EU-US adequacy decision adopted on 10 July 2023, ends almost three years of uncertainty about data transfers compliant with the General Data Protection Regulation (GDPR). The Schrems 2 decision on 16 July 2020 elevated the “essentially equivalent” test to all levels of data transfers. It led to a flurry of compliance activity introducing transfer impact assessments (TIA) as part of supplier due diligence, and various supervisory authority findings against Google Analytics 4.0, culminating in a €1.2 billion fine against Meta for its EU-US data transfers based on ­standard contractual clauses (SCCs).
