If you retain any hope of the cessation of hostilities in the US's war with Iran causing a sudden and large dip in fuel prices, just remember that these stocks need to be rebuilt when all is said and done. And the US isn't the only country with rapidly depleting stocks requiring a post-war rebuild. Refining capacity aside -- there's a long road ahead for high prices.
Strategic petroleum reserves work best when there's strategy behind that which depletes them. It's difficult to see the US's strategy behind exposing itself in this way.
