Some of the issues from the Iranian war are obvious: everyone’s talking about oil and natural gas, for example. Many have mentioned fertilizer. But I think it’s worth going into in a bit more depth.
First is that in addition to gasoline, oil is used to make bunker fuel (98% of freighters and tankers), jet fuel, and diesel (heavy machinery, large trucks.) The prices for all three are rising faster than gasoline prices and there will be a worldwide shortage. Production of semiconductors, phones and so on will shut down some time after that, depending on how the small reserves available are shared out. Taiwan is particularly vulnerable and production can be expected shut down in a couple weeks.
The chart below is from six days ago:

Don’t take the above chart too seriously, I’ve heard different numbers from different sources, and the type of oil in reserve matters a LOT.
This will, of course, hit the AI Bros hard. They have significant stockpiles of some of what they need, but not everything. Worried about that data center coming to where you live? If you’re lucky, Iran has just saved you from an AI driven spike in your energy prices, but not an oil shortage spike!
Airlines are already reducing flights. Expect prices for travel to spike significantly. If you don’t already have tickets for a trip get them now. Even so, it wouldn’t surprise me if many already booked flights are cancelled without recourse, citing forece majeur. Diesel and bunker oil shortages will mean supply line disruptions, and primary processing disruptions. Fertilizer shortages are already changing planting decisions, farmers in Australia are planning on planting much less wheat, for example.
Oil goes into a lot of things. Here are a couple of graphics showing some of them:

And,

To oversimplify, pretty much everything has some oil in it. For example I’m stocking up on NSAIDs and Tylenol 2s (legal in Canada.) I saw one person saying they went out and bought about a year’s supply of pretty much everything which can be stored. One side benefit may be that insane levels of plastic packaging might, at least, be reduced.
China’s bunkering up. No refined oil products are being allowed for export. Fortunately for China, they, unlike apparently almost every other nation in the world, are not run by retards, so they have massive petroleum reserves and they bought about 50% of the world’s grain production for the last four years and stored much of it. But this goes far beyond petrochem: they produce, for example, almost all of the world’s tungsten, and no more exports of that.
Stockpiles in the the West are essentially at zero, right now, and yes, most advanced weapons cannot be made without Tungsten.
There’s been a crash in silver prices recently. You may have read about it. But here’s the thing, there’s an actual physical shortage of it because it’s used in essentially all electronics, including semiconductors and even more importantly, solar panels. Everyone’s going to want solar panels now.
China, not being fools, are no longer allowing export of silver because they know it’s the physical shortage that matters, not the paper price on paper exchanges where delivery isn’t expected to happen.
I spent years railing that just-in-time logistics was sheer fucking insanity and should be outlawed. In addition every country who isn’t a net producer should have at least year’s stockpile of fuel and even net producers should have three years of food stored (because things like droughts and fertilizer shortages happen.) Medication and key medical goods should also be stockpiled. A lot of people are going to suffer and die when key drugs hit shortage and many cancer drugs, for example, are produced in India and on top of the factories not being able to operate without energy, many drugs use petrochemical derivatives directly.
This war should never have happened. Even if it ended now there would be serious shortages for about four to five months, and it would be three to four years before full production could be resumed, if it can be. (Shutting down oil and gas well production often damages the underlying fields.)
Oh, and which major nations will suffer the least? Russia and China. It is to laugh.
I know this is the second article on this subject in a few days, but the impacts of the war are important for you to understand.
