The president of Banreservas recently was interviewed in his first third-party podcast.
Touches on several aspects such as apps from Banreservas are the easiest to use of any Dominican bank, the process to open a checking account and deposit money in their account in their NYC/Miami/Madrid offices (and they get their ATM/debit cards where they live), the increase in financing real estate sold to Dominicans abroad, etc.
He also confirms things such as Banreservas is the largest bank in assets in Central America & the Caribbean. Apparently, Banreservas is going through its best times, but I think that is the case of all the major Dominican banks.
