UK Open Banking hits 1 billion payments milestone

1. The UK Open Banking ecosystem surpassed 1 billion cumulative payments in June, while logging a record 2.81 billion API calls – a 4.4% month‑on‑month rise that underscores growing adoption across the CMA9 banks [2].

Ecosystem growth and performance

Open Banking Limited’s latest release shows the platform has now logged more than 100 billion API calls since its launch eight years ago, with June’s 2.81 billion calls marking the highest monthly volume on record [1]. The 4.4% month‑on‑month increase signals sustained demand for Open Banking‑powered services, even as single domestic payments fell 1.2% in the same period. Variable Recurring Payments (VRPs) offset the decline, rising 6.7% month‑on‑month and keeping overall payment volumes stable [1][2].

Operational efficiency also improved: average response times fell to 349 ms, a 50 ms reduction from the previous reporting window, reflecting ongoing optimisation by ecosystem participants [2]. Faster response times enhance user experience and reduce friction for account‑to‑account transactions, a core benefit of the Open Banking model.

Market implications

While the milestone itself did not trigger a noticeable move in equity indices or bond yields, the data highlights the maturing of a digital payments infrastructure that could influence broader financial‑services competition. Analysts have noted that the UK’s Open Banking framework is increasingly central to retaining consumer and business relationships, though consumer uptake outside the UK remains modest – only 11% of surveyed American users have actually used Open Banking payments [2]. The growing volume of VRPs suggests a shift toward recurring, account‑based payments, potentially reshaping revenue streams for banks and fintech firms alike.

What to watch

• Next data release: Open Banking’s quarterly performance update, expected in early September, will reveal whether API call growth sustains its upward trajectory.
• Regulatory developments: Any amendment to the CMA9 banks’ Open Banking obligations could affect the pace of API adoption and the scale of payments.
• Consumer sentiment: Follow upcoming UK consumer surveys on Open Banking awareness, as shifts in acceptance could impact future transaction volumes.

The 1 billion‑payment milestone confirms that Open Banking has moved from a pilot phase to a core component of the UK’s financial infrastructure, but the next wave of adoption will depend on continued performance gains and broader consumer confidence.
