OBIE publishes Second Open Banking Impact Report

05 November 2021

The Open Banking Implementation Entity (OBIE) has today published its second bi-annual report assessing the impact of open banking on consumers and SMEs. The work relates to an ongoing commitment to track the impact of open banking for years to come. 

According to the new data, adoption of open banking services continues to grow with 8% of digitally enabled consumers estimated to be regular users of at least one open banking service. This has grown from 5.5% in December 2020.  One area that is particularly strong is open banking payments.

Between February and August 2021, there were 11 million payments, compared to 700,000 in the whole of 2020. Recently, HMRC announced it had received more than £1bn in open banking payments, less than six months after launching.

Importantly, if open banking apps and products are to grow in popularity then it’s key that they are easy to use, inclusive and help the customer achieve their financial goal. The data shows over three-quarters (76%) of people saying they will or are likely to continue using the services and 90% reporting they are easy to use and set up. 83% of respondents indicated that they would be interested in expanding their use of open banking-enabled services.

Encouragingly, the findings indicate that growing adoption of open banking services is improving the financial health of the UK. When looking at money management apps and tools specifically, the research has for the first time been able to understand the extent to which customers are seeing positive outcomes in terms of their financial health: 

  • Customers using these apps and tools said that they were helping them to keep on top of expenditure (75%) and keep to a budget (64%), reduce unnecessary expenditure (62%), shop around more (59%) and reduce fees and costs (55%).

When looking at savings apps we saw strong evidence that these services were helping people with their savings, even if some had only recently started using the app: 

  • We also found that 64% claimed the apps had increased their total level of savings. 
  • Of the respondents who claimed their savings had increased: 37% of these customers said they were concerned about their level of savings, suggesting these apps seem to be encouraging consumers who have had historic problems savings start to put aside some money. 
  • We also explored whether the use of open banking saving propositions was encouraging individuals who had never previously saved. Over a fifth (22%) of respondents said this was their first adult saving account. While predictably a higher proportion of respondents aged 45 and over had previously had a savings account, even in this age category use of the app had encouraged new savings behaviour (16%). A quarter of those aged under 45 had never previously saved.   

It is estimated that half of the UK’s open banking users are aged 25 to 44, and that many early adopters of open banking enabled services are typically less experienced and have lower financial confidence.  

Charlotte Crosswell OBE, Chair and Trustee of the Open Banking Implementation Entity (OBIE) commented: I’m really pleased the Open Banking Impact Report points to a continued growth in open banking services. The focus in the past few years has been building the infrastructure completely from scratch. We’re now beginning to see exciting new providers and products emerge with an even stronger pipeline. It’s great to see continued adoption from consumers and SMEs, but importantly seeing that these tools are solving real world issues such as saving and budgeting. That’s really important to me and the best is very much yet to come.”
