There are severe restrictions on exchanging or trading rubles, and Russian companies that receive foreign currencies are forced to convert 80% of it to rubles (I assume this is still in effect, I haven't looked for newer information here). So I don't think we know how the ruble would look like if you could freely trade it, right now the price is not determined by a free market.
