Honestly, not likely
The single biggest sanction in this round is the US stop backing Russian Central Bank. It was never done before and it have a very serious implication.
Because US is the world leading reserve currency, which mean Russian Central Bank (Some 600 billions) are going to be majority in US Dollar either in US or in China, those asset is frozen, last time I heard that is 400 billions. Well, this is not that bad, but. EU and UK also have similar sanction, and altogether it is estimated that 75% of Russian Reserve are gone over night, only left with 15% gold and the rest in Yuan. But still this is just the Piggy Bank
The US also taken away Russian Central bank to raise debt. Which mean they cannot even borrow money to prop up their currency, let's say China is willing to break the sanction and help Russia and lend them everything. You are talking about 1.4 trillions dollar a year, every single year. Seriously, would China want to do that is another business, i mean sure, if Russia can give them back similar amount of resource, but there aren't any, the best Russia can offer is oil and gas, which probably not going to cover half the money
Essentially, Russia become a country without currency. I can't even imagine how a country can survive without its currency.
