“Russia’s Putin has been very much advancing their preparations for any sanctions for several years now.”
They amassed $600 billion in foreign reserves, including their National Wealth Fund, which pays pensions (like social security checks in the USA).
About $300 billion of that has been frozen by Western Governments, and about another $200 billion of it has already been spent during the first five months of the war. Expenses are growing and revenues are declining, so it looks unlikely that the remaining foreign reserves will last till Christmas.
The Russian Government has already defaulted on foreign debt for the first time since 1917, so they are effectively cut off from International credit.
They will be left living hand to mouth for any imports, basically only able to buy from the rest of the world as much as they are are currently making on oil, gas and grain exports, which are being choked hard by sanctions.
Domestically, they are already printing more money at an unsustainable rate. About a 1/3 of all rubles in existence were created in the last five months. Knock your socks off inflation in Russia next year is already baked into the cake, and ruble printing seems to be accelerating.
So he's been preparing for this for some time. Russia's going to hurt some, along with the rest of the world for the shutdown of commerce/trade in many places over covid and sanctions always hurt all countries when Russia gets hammered with them.
Russia will feel it but you can be assured so does every other nation.....however Russia has been preparing for it.
