Oil companies reduced refining capacity during the pandemic and it is still not all back on line. That is part of the problem. Another part is that the oil producers also reduced oil output at the same time as there was no point in pumping out oil when there was a greatly reduced demand. Not all of that pumping capacity is back on line either. When you idle oil pumping capacity and oil refining capacity you just don't throw a switch and you are back running. It takes time to bring the idled capacity back on line after a long period of being idle.

There are also plenty of other issues besides those. Virtually every country in the world is in the same boat. I doubt it matters much who is in power when a storm like this hits the world. It's above my pay grade to say what the answer is to all this.
