Credit Suisse will launch a digital banking app in October challenging fintechs like Revolut in the Swiss bank’s home market by offering free foreign transactions and fully digital wealth management, the bank said on Thursday. Credit Suisse’s new CSX banking app will offer free online banking including a free-of-charge online debit card and other capabilities to be rolled out over months enabling customers to take out mortgages, make investments and plan their pensions, Switzerland’s second-biggest bank said.
