no lah ,crypto currency and SWIFT transfer are two different thingy all togather
SWIFT is an authentication system of real currency transfer...simply put if so much of money can be transferred, without physical notes ,certain authentication is a must ...that the bank indeed has so much money to back it and most importantly ,the receiving bank of SWIFT message must be guranteed its a genuine instruction from an originating bank ...so some kind of code peculiar to each financial institution is used
but had read even that was hacked ,where a Bangladesh bank was robbed a couple of hundred millions by a intermediary bank in Phillipines...I don't have the details with me
If China's quantum encryption as good as they say, they can by pass SWIFT and use RMB crypto direct with their trading partners like Iran.
