Not bank transfers, but https://digiconomist.net/bitcoin-energy-consumption says

> 778,988 - The number of VISA transactions that could be powered by the energy consumed for a single Bitcoin transaction on average (1157.81 kWh).

Obviously bank transactions would also come out way ahead, those are essentially a DB update built on trust and for speed, whereas proof-of-work is severely inefficient by design.

VISA is a credit based system, Bitcoin transation is counterparty free. Transferring gold between countries would be a much more interesting comparision, as gold is the main competitor for Bitcoin.
