Open banking could deliver £43bn annual boost to the UK economy

Open Banking Limited has highlighted the substantial economic potential of open banking in the United Kingdom, with new research suggesting the technology could ultimately generate up to £43bn in annual economic value once fully adopted.

Open Banking  £43bn Annual Boost to UK Economy

The independent economic analysis, conducted by EY, represents one of the most comprehensive attempts to quantify the macroeconomic impact of open banking since the UK became the first major economy to introduce the framework in 2018.

According to the study, open banking has already produced an estimated £8.3bn in cumulative economic benefits.

As adoption continues to grow across consumers and businesses, annual gains could reach £7.4bn after five years, before rising significantly as the ecosystem matures.

A Foundation of the UK’s Digital Financial Infrastructure

Open banking allows consumers and businesses to share current account data securely with authorised third-party providers, enabling new financial services ranging from payment initiation to budgeting tools and automated accounting systems.

The research suggests that as these capabilities expand, the efficiency of everyday financial decisions will improve across the economy.

Payments could become faster and cheaper, businesses could automate administrative processes, and lenders could allocate capital more effectively using real-time financial data.

More than 17.5 million user connections have already been established within the UK’s open banking ecosystem, signalling that the technology is moving beyond early adoption towards broader mainstream usage.

Economic Benefits for Businesses and Consumers

For small and medium-sized enterprises, open banking is expected to deliver significant productivity gains.

By automating tasks such as payment reconciliation and cash-flow monitoring, businesses can reduce administrative burdens and focus more resources on growth.

The EY analysis estimates that improved financial processes for SMEs could contribute around £2.3bn annually to UK GDP within the next five years.

Consumers may also benefit through enhanced financial management tools.

Open banking applications can help households track spending, identify opportunities to save and access financial products that better reflect their circumstances.

These improvements could contribute an estimated £2.5bn annual boost to economic activity over the same period.

Scaling Towards the Next Phase of Open Finance

The long-term projection of £43bn in annual economic value reflects the potential of a fully developed ecosystem in which open banking services become deeply embedded across payments, savings, lending and accounting platforms.

However, achieving this outcome will depend on continued collaboration between industry participants, regulators and government bodies.

Policymakers are increasingly focused on expanding the current open banking framework into a broader “open finance” model that would extend data-sharing capabilities across a wider range of financial products.

Such a transition could unlock further innovation in areas including investment management, insurance and credit markets.

For the UK, which has sought to position itself as a global leader in fintech innovation, the findings reinforce the strategic importance of maintaining momentum in open banking development.

As digital financial services continue to evolve, the ability to harness data securely and efficiently may prove a key driver of productivity, competition and long-term economic growth.
