Seems like Santander are preparing to push a digital only bank into other countries?
Perhaps they want to invest in new technology in a low stakes market while they get everything running, then they intend to move themselves onto the infrastructure in their big markets like the UK afterwards, once all the kinks are worked out of the system?
I don’t know. You’ve got to be pretty sure before you implement a change that will effect 1,300,000 accounts.
The stakes would have been lower if they’d have developed the new platform for a new/fledgeling market and then back-ported it to their home market.
