Russia doesn't really have any banks as we know them outside Russia.
Russian banks have ten year history of embezzeling depositors money.
Most of the 5000 banks which briefly came into existence between 1992 and 1998 have ceased to exist, and those which still do, have never returned their depositors money balances to them. Russia has no checks and credit creds are in very limited use. The Government of Russia has been so corrupt at stealing the country from the Russian people that disobedience of Russian laws including tax regulations is viewed by the Russian population as combating crime. Truly honest merchants can survive only by disobeying their dishonest rulers. This is a situation where the honest Russian people have had to become law breakers to rescue their savings from their rulers, by getting it out of Russia, which their rulers have made a crime.
