Some commentators here are very far from Russian reality. The Russian economy is suffering enormously
Just some data:
The production of passenger cars in the Russian Federation in May 2022 practically stood up, having collapsed in annual terms by 30.3 times (by 96.7%) and having more than halved in 5 months (by 56.4%), follows from the data of the Federal Service state statistics of the Russian Federation (Rosstat). The Russian economy has closely integrated into the world economy and these sanctions has huge influence. With the ruble, the situation is more interesting, the official exchange rate is about 57-60 rubles for 1 dollar, but at this rate you can't buy dollars in cash.
In one thing, I agree that these sanctions won't stop the Russian invasion and the war with Ukraine in the short term, in my opinion, Russia has reserves, at least until the end of this year.
