It will be available only for select retail customers. Well, I hope this will become successful, since one of my major bank I'm using is Union bank, so it's gonna be easier soon to buy and sell bitcoin or eth without leaving the actual facility that hold my fiat.
One of the main thing I'm hoping here is a reasonable transaction fees. By doing it everything directly from the bank, we were able to save some fees already because we have eliminated the use of an exchange or trading platform, Union bank should maximize this opportunity.
