The Gulf of Oman and the Strait of Hormuz are now a dual-blockade zone. The United States struck and disabled a Panama-flagged cargo vessel, the M/V Ocean Molica (also known as the Arika Sun), after it departed an Iranian port and ignored warnings. CENTCOM says it resumed its blockade of all ships entering or departing Iranian ports on July 14 and has since disabled four commercial vessels, turned around 135 ships, and destroyed 10 IRGC-linked tankers. Iran, for its part, claims it has "taken control of the administration" of the Strait of Hormuz and struck an LPG carrier, the NV Sunshine, for attempting to transit via a southern route Tehran considers illegal. The geometry of the situation is straightforward and dangerous. The Strait of Hormuz is the sole maritime route in and out of the Persian Gulf. Before the war began, roughly a fifth of the world's oil and liquefied natural gas transited through it. Both the US and Iran are now using military force against commercial shipping to enforce incompatible blockade regimes — the US to isolate Iran economically, Iran to assert sovereignty over the chokepoint itself. Vessels are caught between two firing lines with no safe corridor. CENTCOM frames this as enforcement against Iran's IRGC "multibillion-dollar shadow network," targeting the revenue infrastructure that funds Iranian military operations. The 135 ships turned back and 10 tankers destroyed represent a serious economic squeeze. But the costs are not borne solely by Iran. Commercial shipping through one of the world's most important waterways is now subject to military interdiction by two hostile powers, neither of which recognizes the other's authority. Senator Chris Murphy's critique cuts to the strategic incoherence: "What is this all for?" He argues the US is spending billions to strike commercial ships in pursuit of leverage that would ultimately result in paying Iran billions to restore the status quo ante. Whether or not that framing is complete, it highlights the absence of a visible endgame. The blockade is a pressure tool, but pressure without a plausible diplomatic off-ramp is just escalation on autopilot. Iran's counter-blockade introduces an additional layer of fragility. Tehran is insisting ships obtain permission to cross through its preferred routes, and vessels attempting the alternative southern-coast route are being struck. The UK Maritime Trade Operations agency reported a vessel north of Qatar hit by multiple projectiles with "several casualties" — the human cost is climbing. The IRGC's claim to administer the strait is a direct challenge to freedom of navigation, and every successful strike reinforces their deterrent posture. The energy market implications are structural, not transient. If approximately 20% of global oil and LNG flows through a waterway where two militaries are actively shooting at commercial vessels, insurance premiums, shipping routes, and energy prices will all adjust — and they will adjust in ways that persist long after any ceasefire. The war's economic blast radius extends well beyond the belligerents. Three months into strict US enforcement, the pattern is set: escalation, counter-escalation, and commercial shipping as collateral. The absence of any diplomatic track visible in this reporting suggests the blockade regime will intensify before it resolves. The Strait of Hormuz has always been the global economy's single most dangerous chokepoint. Now it is an active combat zone with no referee.
