September 2026 · Part 2

Part 1 ended with Riyadh at a counter, deciding whether to pay for passage or fight for it. The second half answered a prior question: who the toll actually lands on, and whether the capitals it lands on can do anything about it.

Hormuz transits run at roughly an eighth of their prewar level, and the bill lands in Riyadh, Tokyo, Seoul, Delhi and Brussels. None of them holds the frozen assets, the oil sanctions or the naval blockade that Tehran wants traded for the key.

Washington holds all three, and Washington can wait. An America that exports oil, with the Americas now pumping around 37 percent of the world's supply, feels the closure as a price at the pump rather than as a shortage, and the administration has tied any renewed bombing to the far side of November's midterms.

The seven-day plan Iran tabled on September 24 was the cleanest offer of the war: hostilities end, at least 12 billion dollars unfreeze, oil sanctions lapse, the blockade lifts, and on the seventh day the strait opens. Trump rejected it two days later, and that refusal is the hinge of the second half.

A closed route is a wasting asset. Every week it stays shut costs Tehran the export revenue the closure was meant to protect, while the blockade and sanctions keep grinding, so the lever earns nothing and the economy pays for holding it.

The cost is showing inside Iran. Authority has drifted from clerics and elected bodies toward the armed elite, and the question of building a bomb is now argued in public, which spends the ambiguity Tehran traded on for two decades.

Beijing read the price before Washington did. On September 16 China's top diplomat received Iran's foreign minister, a week before Xi flew to Washington, to show that the restraint Washington wants from Tehran runs through a capital that bought more than 90 percent of Iranian oil before the strait closed.

Russia and China then vetoed the UN panel that tracked Iranian procurement, so the two governments reported to be supplying Tehran's drones now sit as judges of the evidence against them. Washington keeps its own sanctions and loses the shared record that turned them into anyone else's policy.

The Gulf's producers closed the exit from the other side. By September 30 they were resisting any restart of talks that gave Tehran relief, which means the capitals bleeding most from the closed strait are the ones blocking the one deal that would open it, because a concession to Tehran frightens them more than the closure does.

Saudi Arabia enters October with no working oil exit and a shopping list. Washington refused the crown prince's request for strikes on the Houthis on September 10 and sold him 48 F-35s on September 17, which is the shape the American guarantee now takes: hardware instead of help.

France filled the space Washington left. Its soldiers, radars and air defences at Yanbu are mandated only to protect the terminal, but they put a European army inside an active Gulf war for the first time and buy Paris a seat in Saudi security decisions that Riyadh once reserved for Washington.

The kingdom's own answers show the limit of an air war. A Chinese ballistic missile fired in combat loosens the American hold on Saudi deep strikes, and the chief cleric's ruling that fighting the Houthis is a religious duty is what a government reaches for when its bombs are not producing the result its war aim requires.

None of it reopens the sea. The Houthis hold more of Yemen than at any point since 2014, their missiles now reach Taif and Yanbu, and no one has retaken a coastline from the air in this war or the last one.

Part 1 gave Riyadh two paths, pay or fight. It chose a third, which is to hire, and the hired cover stands guard over a terminal with nothing to load until the pipeline behind it is repaired.

Every Gulf capital is running the same hedge. All six now pair American cooperation with new security partners and direct channels to Tehran, and none of the three has bought safety, because a protector that will not shield you and an attacker that can withdraw relief at will leave exposure rising with no way to lower it.

The one transaction that cleared in September ran through Beijing, and it cleared because Washington could not wait. Rare earths taught Xi in 2025 that pressure on this White House produces retreat, and he landed on September 23 with the licensing regime intact and the soybean card unplayed.

Washington paid in its allies' currency. Taiwan's 14 billion dollar arms package, ready since March, stayed unsigned through the summit and is expected to stay unsigned through the November and December meetings, and the president's own ambassador disclosed that he had offered to sell arms to Beijing.

It paid in enforcement too. Sanctions on the large Chinese institutions financing Iranian oil went unimposed to protect the truce, so the capital that refused Tehran's offer is also declining to squeeze Tehran's biggest customer.

What Beijing gave back was a two-month extension to January 10 and tariff cuts on about 60 billion dollars of goods neither side considers sensitive. Status moved to Beijing, time moved to Beijing, and the hard files, minerals, chips and Taiwan, moved nowhere.

The water tells the same story. Chinese coast guard ships rammed a Philippine government vessel inside Manila's own waters on September 18, blocked the resupply of Second Thomas Shoal and drilled at Scarborough on September 27, each move kept below the line that would oblige an ally to answer, which is the method Part 1 described in the Red Sea.

Allies who watched both transactions drew the same conclusion. Tokyo pre-positioned its Taiwan concerns with Trump the day before Xi landed because it has no seat at the table that reprices its guarantee, and it is buying reach it owns instead, a doubled defence budget, 400 Tomahawks and a unified command.

Seoul refused troops for the Iran war on September 18, absorbed the cancelled exercises, and used its New York meeting to extract movement on submarines and wartime command. An ally that cannot buy the umbrella back is buying its own.

Three dates now set the calendar. The US-China truce expires on January 10 with two more leader meetings before it, the administration has tied renewed bombing of Iran to the far side of the midterms, and Israel votes on October 27 with the Gaza plan frozen until it does.

Riyadh's question is whether French cover and Chinese missiles buy enough time for Marib to hold. Marib holds Yemen's oil and gas, funds the recognised government, and opens the long Saudi border if it falls.

Tehran's question is whether a narrower trade, blockade for blockade, can be found that neither capital has to call a surrender. Both now read any pause as the moment they become vulnerable, which is what keeps a war going after neither side can win it.
