Open banking transactions hit record 15 billion in 2025 as adoption reaches tipping point

Open banking transaction volumes in the UK reached a record 15 billion in 2025, according to the Open Banking Implementation Entity (OBIE), as the payment mechanism crossed what industry observers are calling a genuine consumer adoption tipping point. The figure represents a 67% increase on the previous year and validates years of investment by banks, fintechs, and regulators in building the open banking ecosystem.

The growth has been driven primarily by two use cases: variable recurring payments (VRPs) — which allow consumers to authorise automated payments with flexible amounts, widely used for savings apps and utility bill management — and account-to-account (A2A) payments at point of sale, which bypass card networks entirely and are now accepted by a growing number of UK retailers and e-commerce platforms.

Why the Tipping Point Matters

Consumer finance specialists argue that 15 billion transactions represents a psychologically important threshold. Network effects in payment systems become self-reinforcing above certain adoption levels: as more merchants accept A2A payments, more consumers encounter and use the option; as more consumers use it, more merchants have an incentive to offer it. The cost advantage of A2A over card — typically 0.1-0.2% of transaction value versus 1.5-2.5% for card interchange — means merchants have strong financial incentives to accelerate this shift.

For UK fintech companies building on the open banking infrastructure, the record volume figures are a commercial validation. Platforms such as TrueLayer, Token.io, and Yapily — all London-headquartered — have processed significant proportions of the volume increase and are now in position to leverage that infrastructure for adjacent products including identity verification, income verification for lending, and financial data aggregation for accounting and tax platforms.

International Context

The UK remains the global leader in open banking implementation by most measures, a position that has been sustained by the quality of the regulatory framework established by the Competition and Markets Authority and the Financial Conduct Authority. Brazil, Australia, and the EU (through PSD2 and its successor framework) are following, but the depth of the UK’s developer ecosystem and the quality of the standardised APIs are advantages that will take years for competitors to replicate.
