Iran has not closed the Strait of Hormuz. It has weaponized it. The distinction is consequential — both for global energy markets and for the 2026 midterm elections.
What "Selective Closure" Actually Means
Iran's Foreign Minister Abbas Araghchi said the Strait of Hormuz "is open, but closed to our enemies, to those who carried out this cowardly aggression against us and to their allies." In practice, this means Iran is granting or withholding passage on a country-by-country basis, using Hormuz access as a geopolitical lever.
Iran's ambassador to India confirmed that Tehran allowed Indian vessels to pass through the Strait. Two Indian-flagged tankers carrying liquefied petroleum gas passed through safely and are en route to western India. A Pakistani-flagged Aframax tanker also cleared the strait. A Turkish-owned ship received permission from Tehran and passed through as well.
Meanwhile, Treasury Secretary Scott Bessent confirmed to CNBC that the U.S. is also allowing Iranian oil tankers to transit the Strait outbound. "The Iranian ships have been getting out already, and we've let that happen to supply the rest of the world," Bessent said.
So Iranian oil is flowing out. Indian, Pakistani, and Turkish oil is flowing in. What is not flowing: oil bound for U.S. allies in Europe and the crude streams that feed U.S. Gulf Coast refineries dependent on Gulf imports.
The Strategic Logic
Iran's selective blockade serves three simultaneous objectives. First, it inflicts maximum economic pain on the U.S. and its Western allies while minimizing damage to neutral nations whose support Tehran needs diplomatically. Second, it demonstrates that Iran retains meaningful leverage even after sustaining significant military losses. Third, it drives a wedge between the U.S. and the rest of the world — making it harder for Trump to assemble the coalition he is demanding.
Daily oil exports from the Middle Eastern Gulf have dropped by at least 60% compared to February, according to shipping data and Reuters calculations, forcing exporters to cancel shipments and shut production at oilfields. But that 60% drop is not evenly distributed. Nations with bilateral arrangements with Iran are experiencing something closer to a 20–30% disruption. U.S.-aligned nations are experiencing something closer to 90%.
What This Means for the 2026 Election
The two-tier strait creates a politically explosive dynamic. American consumers are paying $3.72 at the pump — and rising — while Chinese, Indian, and Pakistani drivers are not experiencing the same shock. When that comparison becomes a political talking point — and it will — the incumbent party faces a narrative that is very difficult to counter.
The $3.75 national average threshold — above which historical data shows consumer confidence drops sharply and incumbent party losses in midterms become severe — is now approximately 3–4 weeks away at current trajectory. Every week of selective blockade that continues is a week of political damage accumulating.
The China Decision
The hinge point is China. Trump has suggested the March 31 China summit could be called off depending on Beijing's decision on warship deployment. China's calculation is clear: a bilateral deal with Iran gets them their oil without the military exposure of joining a U.S. coalition. The only thing that changes that calculus is if the cost of not joining — in terms of trade relationship damage with the U.S. — exceeds the cost of joining. That threshold has not yet been reached.
Watch the China summit. It is now the single most important event on the energy calendar.
