The UK's payments landscape has undergone significant changes with the introduction of PSD2 and Open Banking, and as such, the government is undertaking a review to ensure its continued development. Plaid, a company that connects 3,000+ apps and services to 11,000+ financial institutions, highlights key limitations and opportunities in the open banking ecosystem, including the need for stronger customer authentication, payment initiation services, supervision and enforcement, and consumer protection. To maximize adoption of open banking services, the government should remove the 90-day re-authentication requirement, grant more supervisory powers to regulatory bodies, and refine the liability model to avoid higher costs for consumers. The UK has a unique opportunity to take the lead globally in financial innovation and Plaid supports the government's objectives for the development of the UK payments network.
