The move by Jiko, which bills itself as a new kind of bank, gives it broad access to the highly-regulated U.S. market. Fintech firms have to choose one of three ways to break into this market: acquire a banking institution, apply to become a chartered bank, or partner with an existing lender. That U.S. regulators blessed the Jiko transaction is significant mostly because of how fundamentally different it is: It’s a consumer bank that doesn’t hold deposits.
