Latest news coming from Ripple president Brad Garlinghouse, said “I have said it before that by the end of 2019, the xRapid ledger will be a significant tool in banks around the world. Before 2019 comes to an end, I believe that dozens of banks will embrace Ripple.” which for me is not possible to imagine though. currently the american express is using the xrp ledger to their transactions made.
I believe, soon many banks will follow and use blockchain technology to their system.
