Open banking was expected to revolutionize financial services in Europe, but years after its introduction, adoption has fallen short of expectations. While regulation like PSD2 laid the groundwork for greater financial data sharing, the actual implementation of open banking has been fragmented, inconsistent, and underwhelming. Many financial institutions still treat open banking as a compliance exercise rather than an opportunity for innovation, leaving consumers and businesses with limited, disjointed experiences instead of the seamless financial ecosystem that was promised.
In this exclusive interview recorded at FinovateEurope 2025, David Barton-Grimley, Strategy Director at 11:FS speaks with Finovate VP Greg Palmer to discuss why open banking has floundered in Europe, the underlying issues slowing adoption, and what needs to change for it to deliver on its full potential. From poor API standards to a lack of clear monetization strategies, Barton-Grimley explores some of the underlying implementation issues and addresses how financial institutions can shift their approach to make open banking work for both consumers and businesses.
“Too often the conversation about open banking is very binary,” Barton-Grimley said. “Is it successful, and what does success even mean in this category? It is growing, and we are seeing year-on year multi-digit uptake of it as people are getting used to it and using it.”
