Seven months into the US-Iran war that began February 28, the Strait of Hormuz has become less a battlefield than a toll booth operated by two competing authorities — neither of which can dislodge the other. Iran's IRGC insists the strait is closed to uncoordinated traffic, publishing blacklists and extracting fees. The US Navy claims it is shepherding 13 million barrels per day through an alternate route. Both assertions are partially true and mutually incompatible, which is the entire problem. Iran's latest diplomatic offer — a seven-condition package presented at the UN General Assembly to reopen Hormuz within a week — was rejected by Trump before it could be formally transmitted through mediators Pakistan, Qatar, and Oman. The conditions largely amounted to restoring the June memorandum of understanding: lift the naval blockade, release frozen funds, end attacks on all fronts including Israel's assault on Lebanon. Tehran says it awaits an official response. Washington says the answer is no. The military reality on the water is controlled attrition. Explosions were reported near Qeshm Island hours after Trump's rejection, with Iranian media describing antiship missiles and drones fired at vessels transiting without Tehran's approval. An Indian cargo ship was attacked last week, killing a sailor. The IRGC released video of a second seized US underwater drone. Iran's Persian Gulf Strait Authority announced it would blacklist charterers ordering crews onto unauthorized routes and published what it called an apology from a shipowner who tried. Andreas Krieg of King's College London identifies the strategic logic clearly: Iran cannot impose mutual financial sanctions on the US, so it escalates through the only lever it has — physical control of maritime chokepoints. His assessment is that the next Iranian moves will be more aggressive vessel interdictions in Hormuz, attacks on Gulf energy infrastructure, increased Houthi pressure around Bab al-Mandeb, and operations against alternative Saudi export routes. The pressure on Hormuz, the Red Sea, and Saudi infrastructure is already interacting as a system. The US military posture is blockade plus escort. Central Command claims to have redirected 122 commercial vessels to enforce the naval blockade of Iranian ports, halting all Iranian crude exports. A September 19 operational update claimed more than one billion barrels of crude moved out of the Gulf over roughly two months. Energy Secretary Chris Wright cited a running average of nearly 13 million barrels per day. These numbers project control. Whether they reflect the full picture of disruption costs — insurance premiums, rerouting delays, destroyed vessels, dead sailors — is a different question. The structural problem is that both sides have locked themselves into positions where de-escalation looks like capitulation. Iran cannot reopen the strait without the blockade lifting; the US cannot lift the blockade without Iran conceding on nuclear and regional issues that predate this war. Iranian military spokesman Mohammad Akraminia warned that conditions were deteriorating so badly for the US that it might launch another military aggression. IRGC spokesman Abolfazl Shekarchi said any further US intervention would be met with force. These are not off-ramps. Krieg's forecast for coming weeks: further attacks on tankers, US-enabled shipping, and regional infrastructure, followed by limited US strikes on IRGC maritime assets, coastal missile positions, and vessels. A tit-for-tat cycle that has already re-emerged around Hormuz. The most likely level remains controlled attrition rather than a return to the massive air campaign of the opening months. This is the new equilibrium — and it is enormously expensive for everyone except the two combatants' military establishments.
