You are right about the countries wanting to protect their own banks. We're not suggesting a "savings account" in the sense that you keep your money in a foreign bank. This is more like an efficient "bank proxy". Does "nginx for banks" explain what I'm trying to say? The money at the end of the day will be kept in your own banks.

Your point about foreign transaction fees is also correct in part. There are many layers of fees in a foreign transaction, many portions of which are directly controllable by the parent bank as is already proven by services like Revolut and centtrip.

Not much can be done about the remaining charges but even the savings that can be done with the help of a parent bank are very substantial and within the bounds of regulation.
