While all this has been going on, the arsenals of many western nations have been funnelled into Ukraine. It's not clear to me what proportion is actually making it to the front line, but large amounts of it are being blown up by Russia as they're being transported, as Russia maintains its air superiority (with a Ukrainian plane occasionally cropping up and then being immediately shot down). As a further display of force, Russia has used a hypersonic missile to demonstrate that it possesses the technology, and nothing other than several tens of meters of metal or an even faster missile can stop a hypersonic missile, and the US doesn't seem to have them yet, so Russia has shown that it can strike almost anywhere in Europe in about ten minutes. While all these weapons being used, even if they're then being immediately destroyed, benefits the military-industrial complex greatly, it's getting to the point now where some nations are having to stop pouring arms into Ukraine because otherwise they'd have nothing left for themselves. Greece is in this position, and I think Germany might be there shortly. Ukraine is going through something like a week's worth of equipment every day, and, for example, it will take the US, with its limited industry, years to replace what Ukraine has already lost in a month or two. The combined might of the west is not causing major issues for Russia.

How is Russia faring with the rest of Europe? After a sanction blitzkrieg, the Russian fortress economy is ticking along okay. Not amazingly, but the worst effects have been contained, and due to parallel imports and a loose-but-strengthening alliance with China and Central Asian countries including India, Russians are generally okay considering the situation as a whole. The ruble is now on a gold standard and is roughly back to its pre-invasion levels. Russia has demanded that all non-friendly countries (which includes basically all of Europe) pay for its natural gas in rubles, which some are doing (e.g. Hungary and I think Austria), but many are not, including Germany, which relies quite heavily on Russia's gas for its industry and power. The alternative is to cobble together imports from other countries such as Algeria, which won't be sufficient, or to buy it from the US. However, the US's production and transport is already at capacity, meaning that natural gas given to Europe will mean taking it away from other countries, such as in Asia. Additionally, Europe does not have enough port terminals to receive gas transported on tankers, and won't have that capability until 2025-6. There has been a large amount of messaging from the German government to its citizens to prepare for electricity shortages and try and make do with much less - don't drive if you can avoid it, take fewer showers, and so on, but these measures won't save German industry for very long. Also, Finland and Sweden are likely going to join NATO, and in response, Russia is going to strengthen its border there and make sure there are nukes nearby if NATO decides to advance there.

In addition, there has been economic calamity around the world due to price increases in fertilizers and food - the former requires natural gas to make, and the latter requires the former and is also supplied in significant amounts from Ukraine and Russia. Diesel is also facing major shortages, which is used to transport goods around the globe as well as power agricultural equipment. In response to these changes, countries are either strengthening trade with Russia, and/or trying to become self-sufficient, but these are major changes to make in only a few months and so we will likely see major food shortages around the world before too long. As countries slowly switch from the Western sphere of influence to the Eastern sphere, backed up by the massive material and commodity suppliers that are Russia, China, and India, we may see some very deranged shit. Expect some regime changes and wars. Iran better watch out. @granit, among others, has done some very good posts on the economic side of things, so check them out if you're interested.
