The Russian banking system is facing very difficult times in connection with the military attack on Ukraine and the imposition of the most severe international sanctions. Russian banks are cut off from SWIFT, half of the foreign exchange reserves are frozen in foreign banks and there is a high probability that these funds will be transferred to Ukraine to restore the damage caused by Russia. Business is leaving this country, the supply of high-tech components is severely disrupted, inflation and unemployment are growing.
But in any case, states will issue their own CBDCs, it's only a matter of time.
