The US isn't insulated from global oil supply shocks because crude oil and refined petroleum products are traded on global markets and natural gas is somewhat traded on global markets (there are limits to LNG exports).

So yes the US could limit or ban exports. Many countries (including China) have done this in a kind of energy nationalism, but that hangs out allies to dry in a way that would make the US deeply uncomfortable. It would threaten European energy security. It would come at the cost of Latin American exports. So there's a cost to pay.

And more to the point, no US government regardless of party is going to hurt corporate profits by limiting exports. Biden could've done it in 2021-2022 and didn't. And Trump certainly won't. As one example, a big release from the SPR was on an oil-for-oil basis. Rather than cash ii on high prices, it's just a massive gift to oil companies who have to repay the oil (and then some) at some unspecified future point when oil will be cheaper. That's billions the US could've added to government coffers.

I do agree there is a power shift going on but not because of US energy independence. No, it's because the US cannot militarily protect GCC countries and cannot force open the Strait of Hormuz or guarantee global shipping, which has essentially been a US guarantee since 1945.

I do think this administration does want to crack OPEC but that's likely to be of massive benefit to China without China having to do anything.
