I think we should consider that the ME oil = world economy narrative may be overestimated.
The US is self sufficient already and they're also supplying the EU. The "world economy" is already in shambles, the EU is in a recession since 2022, yes markets will crash, commodity prices skyrocket, but we should consider that in actual practice the impact on the west may not be as big as people are assuming here.
The calculation may well be the pain is worth it because the US isn't going to be the one suffering the most. If this is what they believe then all this calculation based on "the US can't do X because it would destroy the Gulf oil production" is moot.
Also it goes without saying it is China the one to lose out the most if we have another commodities boom. It is China the one primarily looking for cheap oil and cheap food, not the US.
I do not think institutional investors will let oil e.g Brent go over 100-120 in the worst case. Assume they could be wrong by 2x, hitting 200+ seems like a WW3 scenario and Gulf oil is very short of that yet.
There is absolutely way too money to be made by manipulating the price up and down.
They have spent the last 2 years pushing the China "weak demand" narrative in order to push oil price down. There are billions and who knows how many huge players deeply invested into shorting oil for the long term. Some of them are getting out now but not everyone, in fact nothing ever happens gang exist in the financial market too and the "China weak demand" narrative will stay dominant.
