The article analyzes the FCA's new unified reporting regime for Material Third-Party Arrangements (MTPAs), introduced under FCA policy statement PS26/2 and the revised FCA guidance, which takes effect on March 18, 2027. From that date, the FCA, alongside the Prudential Regulation Authority (PRA) and the Bank of England, will replace legacy outsourcing frameworks with a single reporting regime, requiring regulated entities to deliver real-time notifications when they enter or significantly modify an MTPA and to submit a comprehensive annual register via the FCA’s online Connect platform.
