It depends on what is sanctioned or may be. We can expect bread prices to increase as oil and gas already has - again recently, without sanctions.It could be a case of economic M. A. D.
People in the USA are already moaning about fuel prices. Biden released a couple of days usage of fuel from his strategic reserves - sort of typical political act, sounds good but doesn't really help. He then attempted to get the producers to release more. I think the USA and ?? Qatar did but the rest didn't. Qatar is an odd place. Tiny population and way more foreigners living there. Currently having a go at Airbus, maybe a USA aspect to that.
The money put into Russia is interesting. It will be expected to show a return. What happens now. Putin has said he may apply his own sanctions. We seem to have a lot of telepathic politicians around that know what he is thinking. Just like all he uses rhetoric. He sees communism as a dead end. Russia banned it's communist party. He has interfered with other parties. We have no idea at all what they were at. The place has a problem, it's Russian so must be bad.
Some how I think his moves so far are essentially strategic and the NATO aspects relate to what gets stationed in Europe by the USA. It seems that he warned that moves would start up the arms race again. It seems to have done, He has his new toys and Biden has massively increased defence spending. Strategically to some extent he doesn't need to do any more than he has.
