The U.K.’s open banking system has now powered more than 1 billion payments. That’s according to an announcement Tuesday (July 28) from Open Banking Limited, which also noted a second milestone: the system has now logged 100 billion API calls across its member banks since the debut of open banking more than eight years ago. In other open banking news, recent PYMNTS Intelligence research shows that while many institutions see open banking as central to retaining consumer and business relationships, consumers are not totally sold on the concept. According to “Consumer Sentiment About Open Banking Payments,” completed in collaboration with Trustly, roughly 46% of American consumers said they would be willing to use open banking payments for at least one type of purchase, with monthly bills, groceries and subscriptions attracting the most interest. Still, just 11% of those consumers reported using an open banking payment.
