Western nations have steadily ratcheted up sanctions on Russia since it invaded Ukraine last week, including shutting out some Russian banks from the SWIFT global financial network.

The measures have hammered the ruble and forced the central bank to jack up interest rates, while Moscow has responded to the growing exodus of Western investors by temporarily restricting Russian asset sales by foreigners.

Russian firms, meanwhile, have felt increasingly squeezed. Sberbank, Russia’s largest lender, said on Wednesday it was leaving the European market because its subsidiaries faced large cash outflows. It also said the safety of its employees and property was threatened.

Signalling there would be no let up from the West, U.S. President Joe Biden said in his State of the Union address on Tuesday that his Russian counterpart Vladimir Putin “has no idea what’s coming” as he joined European states and Canada in closing U.S. airspace to Russian planes.
