It is direct consequence of sanctions. Suddenly, many people discovered that they don't really need USD/EUR to buy nearly everything they need from abroad. There was build interesting unofficial scheme to circumvent the IMF order about international trade only in USD/EUR for Russia. Foreing companies opens accounts in Russian banks in their own currencies. Some buy things from Russia, some sell things to Russia. And money does not even cross the border. I don't know how long that will work, but it is much easier and reliable to trade with foreign countries, because local currencies rates to RUB is much less vulnerable for high-frequency trading and there is very low probability to catch losses on the rate change during transaction unlike with USD/EUR.

Really, there is very little things West have to offer now. West mostly destroyed its manufacturing and allowed China to become wordwide factory and India worldwide chemical synthesis kingdom. And it is easier and cheaper to buy even Western stuff from China/India. From western cars spare parts to the complex industrial equipment. Even fucking iphones. You think they disappear or become very expensive? No. They become cheaper, because now they imported from China unofficially for yuans without all that official stores and services additional expenses.

IDK if that will last long, since that stupid bitch, Central Bank of Russia CEO Nabiullina who continue to push IMF agenda was set for another term, and she definitely will try to restrict anything that is against IMF orders, including that trick with non-crossing-border international transactions.

Interesting, that only thing government really did useful during all that time was allowing "grey" import, i.e. unofficial importing of branded things. Few months ago you could not import a batch of iphones if you are not an Apple representative and this is not officially authorized by Apple import deal. Now that restriction repealed, so anybody could import any branded things from anywhere without any control of trademark owner.
