This is reported by the Financial Times newspaper.

As noted, Italy's largest bank UniCredit this week said it had reserved more than €1.2 billion for possible losses in Russia, and also warned that it could lose €5.3 billion if it was forced to leave Russia completely. 

The French bank Societe Generale is preparing to lose about €3.1 billion.

Earlier it was reported that Western companies that leave the Russian market are forced to "play with fire" and suffer heavy losses due to the "painful exit" from Russian projects.

As Russian President Vladimir Putin noted, many companies claim to be leaving the Russian market, "but not leaving."

For some foreign companies that hastily left Russia, it will be harder to come back than to leave, Dmitry Medvedev, deputy chairman of the Russian Security Council, said.
