you are saying russia needs foreign reserves to use in russia? Russia uses the ruble in russia.In short term? Nothing. There are still foreign reserve within Russia that Russian can use, and until that has depleted, nothing will change. But once that has been depleted, then depends on how much China help out, it range from business as usual to everything close down and Russia went back to coupon system for just about everything.
I don't know how long Russia can hang on to those foreign money and I don't know when will the West lift the sanction, so I cannot tell you what will happen in a year or so.
It only needs foreign reserves for trade with other countries that demand a hard currency.
countries have their own currencies for domestic use.
so you're still arguing with yourself about who is winning?A winning side would never put land-mines in their territory. This is proof that the Ukrainians know that it is just a matter of time before the Russians seize Odessa.
