In France, the bank 'Société Générale' did that 15 years ago, 5th biggest French bank and at the time they decided to do that, probably the bank with the best IT systems (they had less legacy systems than bigger banks and did better tech choices). It's now still the 5th biggest bank, they bought an online bank, and are restructuring because of all the French banks, it's the one that spend the most in IT (at least it was 2 years ago). The CFO/CEO who pushed for this got out with a lot of money (Oudea, his wife is in charge of the Olympic games this summer).
