UK Open Banking Hits Landmark One Billion Payments and 100 Billion API Calls
By Lauren Towner · 28 July 2026

Quick Summary
The UK Open Banking ecosystem has officially surpassed one billion payments and 100 billion API calls. This milestone reflects the maturity of account-to-account payments and the increasing adoption of Variable Recurring Payments by millions of UK consumers and businesses seeking faster, more efficient financial management tools.
How is Open Banking Scaling in the UK?
The UK has solidified its status as a global fintech leader by processing over one billion payments through major high street banks. This growth is underpinned by a massive 100 billion API calls across the CMA9 banks since the framework's inception eight years ago. In June 2026 alone, the ecosystem handled 2.81 billion API calls, marking a 4.4% month-on-month increase and setting a new record for network traffic.
- Total API calls: 2.81bn in June 2026
- Total monthly payments: 40.16 million
- Network Availability: 99.80% weighted availability
What Role do Variable Recurring Payments Play?
While traditional single domestic payments saw a slight dip of 1.2%, Variable Recurring Payments (VRPs) are emerging as the primary engine for payment innovation. VRP volumes grew by 6.7% in a single month, reaching 7.73 million transactions. This shift suggests that users are moving beyond one-off transfers toward automated financial sweeps and recurring billing solutions powered by Open Banking infrastructure.
How Has Technical Performance Improved?
The maturity of the UK's financial infrastructure is evident in the latest technical benchmarks. Average response times for payment requests have dropped to 349ms, a significant 50ms improvement over the previous period. This speed, combined with a 99.35% unweighted availability, ensures that Open Banking remains a reliable alternative to traditional card rails for both merchants and consumers.
FF NEWS TAKE:
Hitting one billion payments isn't just a vanity metric; it proves that Open Banking has moved from a regulatory experiment to a core pillar of UK finance. The surge in Variable Recurring Payments is particularly telling, as it signals the long-awaited transition toward Open Finance. This scale effectively challenges the dominance of card schemes, offering a faster, more cost-effective rail for the digital economy.
