The exodus from Russia accelerates as those with money and brains seek a way out, they are voting with their feet. Confidence in Putin and the Russian government must be at an all-time high, optimism and confidence is overflowing in Russia and flowing across its borders!
By the time Russia gets to sell its oil again demand should have fallen off significantly and the price low with a crowded market of sellers, in a dwindling market. I think the oil business is going to have some big changes starting in about a decade as EVs predominate and alternative energy sources with green new grids and energy storage increase steadily. Russia's entire oil infrastructure might have to be rebuilt requiring significant capital investments that won't be there and neither will the market. Russia without oil revenue has a bleak economic future. All their foreign assets should be seized and given to Ukraine as compensation at that point and Ukraine could displace them as the European energy supplier during the next decade, they have the proven reserves to do it.
