UK Open Banking in 2026: Where the World's First Major Open Banking Program Actually Stands

UK Open Banking launched in January 2018 as the world’s first major open banking program — driven by the Competition and Markets Authority’s order against the nine largest UK banks (the “CMA9”) and overseen by the Open Banking Implementation Entity. Eight years in, with the Open Banking program transitioning to the new Joint Regulatory Oversight Committee (JROC) framework and the broader Smart Data initiative emerging, the question for 2026 is whether the original ambition has been realized.

The honest answer: partially. Adoption has been substantial — 11+ million active users by mid-2026 — but the original vision of disrupting the banking landscape with new entrants has had more modest impact than initial projections suggested.

The numbers#

A few orienting facts in 2026:

• 11-12 million active monthly users of Open Banking services.
• Roughly 25-30% of UK consumers have used Open Banking at some point.
• Active third-party providers (TPPs) number in the low hundreds.
• API call volumes are in the billions per month.
• Payment initiation has reached meaningful volume — particularly for Variable Recurring Payments and one-off payments where the open-banking flow is competitive with card payment economics.

The user growth has continued through 2023-2026, though the rate has been steady rather than explosive. The use cases producing the highest adoption are personal financial management, sweeping and account-funding for new financial products, and increasingly payment initiation for specific commerce flows.

What the use cases actually look like#

Personal financial management — apps that aggregate balances and transactions across providers. Money Dashboard (now part of Mode), Yolt (now sunset), Plum, Snoop, plus a long tail of newer entrants. The category remains the largest by user count but has not produced the breakthrough business model that early proponents envisioned.

Account aggregation for credit underwriting — the use case that has produced the strongest unit economics. Lenders pull bank data via Open Banking for income verification and affordability assessment. Credit Kudos (now part of Apple), TrueLayer’s underwriting products, and many embedded lending platforms use this.

Account opening / account funding — moving money from an existing account into a new account at sign-up via Open Banking payment initiation rather than card payment or manual transfer. Used widely by trading apps, savings apps, and new bank accounts.

Variable Recurring Payments (VRP) — the newer category, in operational deployment from 2023. VRP allows recurring payments under defined limits and conditions without per-transaction authentication, similar in spirit to direct debit but with consumer-controlled limits and the open-banking infrastructure underneath. The big push from 2024-2026 has been “sweeping” (automated movement between accounts of the same beneficial owner) and commercial VRP (one-time consent for variable payments to specific merchants).

Identity verification — a growing use case where the bank data is used as an identity signal rather than a financial one.

The JROC transition#

The Open Banking program’s governance has shifted. The original Open Banking Implementation Entity wound down its core mandate in 2023-2024; the JROC (Joint Regulatory Oversight Committee) — bringing together FCA, PSR, CMA, and HMT — coordinates the broader Open Banking future. The new Open Banking Operator (Open Banking Ltd. in its evolved form) operates the technical infrastructure.

Key consequences:

• More distributed governance rather than single-entity oversight.
• Funding model shift — the cost of operating Open Banking has been increasingly borne by participants rather than by the CMA9 banks.
• Strategic direction under the broader Smart Data initiative.

The Smart Data initiative#

Beyond banking, the UK government has been extending the open-data-with-consent pattern to other sectors:

• Smart Data in energy — the long-running Smart Data Foundry work plus the various energy-data-sharing initiatives.
• Smart Data in telecommunications — extending similar patterns.
• Smart Data in pensions — the Pensions Dashboards initiative.
• Cross-sector Smart Data — under the Data Protection and Digital Information Act framework.

The ambition is to make UK Open Banking the template for a broader Smart Data regime. The execution has been measured.

How UK compares#

A quick comparison with other Open Banking / Open Finance regimes:

• vs. EU PSD2 / PSD3 — UK’s program was first, with more focused governance and more aggressive technical standardization. EU’s program has broader scope but has had more variable implementation across member states.
• vs. Brazil Open Finance (covered here) — Brazil’s program is broader in scope, more centrally-mandated, and has produced larger transaction volumes.
• vs. India Account Aggregator (covered here) — India’s framework has different architecture (the AA as a separate regulated entity) with comparable outcomes.
• vs. Australia CDR — Australia’s Consumer Data Right has similar ambition with slower execution.
• vs. US — the US has had no equivalent framework; the CFPB’s 1033 rule is the closest analog and is still in operational stages.

The UK’s first-mover position has produced both advantages (mature ecosystem, established standards) and challenges (legacy decisions that newer regimes have improved upon).

What’s coming in 2026 and 2027#

Three things to watch:

Commercial VRP scale-up — the next major use case category, with substantial 2026 deployment activity.

Smart Data extensions — the framework expanding to additional sectors.

The CFPB 1033 implementation in the US — the closest US analog to Open Banking, with implications for cross-Atlantic comparability.
