The milestone comes six-and-a-half years after the rollout of open banking in the UK, building an ecosystem worth more than £4 billion to the economy and creating around 5000 skilled digital jobs, claims Open Banking Limited (OBL).Payment Initiation Service users are up 61% year-on-year, while Account Information Service users have grown 27% year-on-year.Marion King, OBL chair and trustee, says: “Consumer empowerment is core to open banking and it’s fantastic to see more and more people and small businesses take advantage of the financial opportunities open banking provides. “From access to cost-effective credit, building a regular savings habit or making more informed financial decisions, open banking is delivering the means for millions of people to improve their financial wellbeing, delivering a true public good.”The OBL says that competition has been a key driver to growth, noting that when one company focuses on open banking technology its direct competitors soon follow. The 10 million mark comes days after the government committed to introducing smart data powers through a new Digital Information and Smart Data bill. This legislation will lay the foundations for future growth of the open banking ecosystem, says the OBL.
