I'm guessing they'd probably send that another way.
The bank would either go and just write on a piece of paper who owes who or they'd transfer other assets. Quite frankly they would probably have to print money in order to get $200 billion to send.
Although as mire financial institutions adopt xrp then the price will probably have to go up.
Based on my research, you cannot print XRP. Am I wrong?
They don't need to print money they use nostro account where already money is deposited & A payment journey with xRapid looks like this: a financial institution connects directly to digital asset exchanges in both the originating and destination corridors. The originating currency is exchanged into XRP which provides the necessary liquidity to power the final payment, and then in seconds that XRP is exchanged into the destination currency in the second digital asset exchange. Once this transaction takes place, the funds are sent out on the local rails of the destination country for payout. The transaction is tracked end-to-end, and the result is a cross-border payment that is cheaper and faster than ever before.
