Something I was thinking about should Iran end up turning the Strait of Hormuz into a tollbooth is how Russia used the Nord Stream pipeline in the months after their invasion of Ukraine before the pipeline was destroyed. At any point they could, and did, throttle gas supply in an attempt to bend Europe (mainly Germany) to their will. Remember the criticism of Germany only sending helmets and blankets as aid early in the war? How much that's attributable to fear of disrupted gas flows vs. broader German handwringing in the first few months is debatable but Russia clearly thought flow through NS was a source of influence. Russia even shut down flow due to "maintenance" as natural gas prices peaked in the summer of 2022.
Similarly, Iran with a toll regime in place will use its leverage over the Strait to protect its allies in the region. Say Israel wants to cross into Lebanon to deal with Hezbollah, Iran threatens to close the Strait in response. We're at basically peak political capital for re-opening the Strait right now and the desire from anyone other than the Gulf states to do so seems extremely limited - for good reason. A new US admin takes over in '28 that has no appetite for getting involved in re-opening the Strait and the can gets kicked further down the road.
Best case scenario for energy supply if the Strait isn't re-opened by force or through regime change, is Iran re-opens it with a toll in place for a couple years, Saudi Arabia twins or triples the E-W pipeline which brings the toll down and the Strait, and Iran's influence, becomes less relevant. Probably a $10B or so project which is in the ballpark of what Iran stands to collect in toll fees yearly.
