Thinking about it more I would expect the opposite.
I.e. there would be an imbalance of people wanting to sell Rubles to buy USDT/BTC/Eth etc... as a currency hedge/escape route.
But this discount is implying the opposite...
Arh - so does it imply that exporters are using Binance to convert USD->RUB as I am assuming this just became hard. So happy to pay 10% to do this?
So effectively Binance is being used (in a very small way - RUB volumes are tiny millions a day not billions) to avoid sanctions?
More people selling rubles actually means that the price of the Russian ruble will go down.
I don't know what are you trying to say with "this discount is implying the opposite"?Do you really mean that the rubles will get more expensive,only because more people want to sell their rubles?This is quite the opposite of the law of supply and demand.
I don' think that Binance can be effectively used for avoiding the western sanctions.Binance is a custodial exchange,which supports KYC.I'm sure that Binance will comply with the financial restrictions,which are imposed by the big western governments.
The western financial sanctions are pointed towards the Russian elite,not the ordinary Russians,who are trading on Binance or the foreigners,who are trading with Russian rubles.
