Putting all the general Anti US propaganda BS in the statement aside ...
About 50% of all payments into Russia are still outside SWIFT/BIC since years and must be done by fax order etc. because Russian Banks still do not use! The rest of 50% are those payments done to Western banks having offices in Russia and where Russian companies have a bank account. These payment must be done with including BIC/SWIFT further by law ... and if not, these banks will loose licenses in the USA. So you can imagine that they will more closing their Russian branch as too loose the US market.
So at least a big statement and ridiculous announcement for nothing!
P.S.
Personally I'm not happy with the by the US full controlled SWIFT/BIC system ... no miss-understanding.
