When the war is over (depending on outcome), oil prices will drop as soon as trade can be reestablished.
Provided, of course, that those who would hold the shipping through the Straits for ransom are denied that power. This means a regime change in Iran, a 'fundamental transformation' back to secular government and an end to the 12er theocracy.
Failure to accomplish that will mean that at any time the regime can hold 20% of the world oil supply for ransom, either directly by controlling shipping, or indirectly, by attacking and destroying any attempt to bypass that shipping route.
I believe the Gulf States understand the score.
This is why any conclusion must include the removal of the present regime in Iran from power, not only to neutralize the direct threat (and free the Iranian people), but to undermine proxies which currently derive their potency from Iran, and which would continue to operate. Those proxies must also be removed from the board.
This is a foreshadowing of what is coming for any Western Republic or Democracy currently feeding (literally, through social programs) their own growing threats to their way of life.
Disinformation campaigns, propaganda, and the cognitive disconnect of Leftists preaching 'tolerance' have led many to believe there is some cozy middle ground, but there is not.
Some cultural differences are too great to assimilate without fundamental change, and for the West, that is an existential threat.
