For a few weeks in September it looked as if the Gulf was quietly healing. Tankers were moving again, crude exports were climbing back toward normal, and markets had started to treat the Strait of Hormuz as a solved problem. October has punctured that assumption. A fresh wave of strikes on shipping, combined with a sudden escalation between Saudi Arabia and Yemen's Houthis, has turned the region's two great maritime chokepoints back into the most important variables in the global economy.
The story is no longer only about whether oil gets through. It is about who can credibly claim control of the sea lanes, how a stalled US-Iran negotiation is being fought through proxies and pressure, and how a war that began in late February is now bleeding into domestic politics thousands of miles away.
The numbers explain why October felt like a reversal. According to Kpler data cited by Al Jazeera, Gulf oil flows excluding Iran had recovered to more than 81% of pre-war levels in September, and Middle East crude exports exceeded pre-war levels on 14 separate days. Before the war, roughly 125 large commercial vessels crossed the strait each day, carrying about a fifth of the world's crude and liquefied natural gas supply.
Then the attacks resumed in earnest. Kpler counted 10 tankers struck between September 28 and October 4, with another hit on October 5. The UK Maritime Trade Operations centre recorded 15 more attacks between October 6 and 14, eleven of them in a single four-day stretch. The effect on flows was stark: about 20.8 million barrels passed through on October 8, but only 2.9 million on October 11, against a pre-war daily average of 17.1 million, the same report noted. Brent crude climbed to $106.58 on October 14.
The lesson is that a chokepoint does not need to be closed to be disrupted. It only needs to be unpredictable enough that crews, insurers and shipowners hesitate. Analysts quoted in the coverage pointed to high crew bonuses and elevated insurance rates as part of the cost of every transit, and those costs persist even on days when ships do get through.
Both Washington and Tehran are now making public claims about who runs the waterway, and those claims are themselves part of the contest. US Central Command posted that the commander of Iran's Revolutionary Guard navy "has no navy" and that "American forces and regional partners clearly control the Strait of Hormuz," adding that US forces helped Gulf partners move more than 19 million barrels of crude on October 13, Al Jazeera reported. Secretary of State Marco Rubio has said Iran lost "complete control" of the strait, according to an earlier explainer.
Iran tells a different story. Its navy announced new units east of the strait and across the Sea of Oman and Arabian Sea to carry out "real time surveillance," and warned vessels not to switch off their transponders. Security chief Mohsen Rezaei said that "the strait is under Iran's control, and we manage it," while accusing the US of shuttling oil via smaller vessels. An Iranian official told Reuters that Tehran had adopted new offensive tactics roughly ten days earlier, with one aim reportedly being to influence the US midterm elections, per the same report.
Chris Featherstone of the University of York offered perhaps the most useful framing: neither side fully controls the strait, and Iran's attacks are designed to show that Washington does not either. In other words, the contest is as much about credibility as it is about tonnage.
While Hormuz dominates the energy conversation, the more dramatic escalation of the past fortnight has come from Yemen. After the Houthis seized the Red Sea port of Mocha and Mayyun Island in the Bab al-Mandeb Strait in September, Saudi-backed government forces launched a counteroffensive. The fighting has since jumped borders. An attack on Riyadh's King Khalid International Airport on October 10 killed at least 13 people and injured more than 300, and a second projectile two days later killed one more person, Al Jazeera reported. Airlines including Lufthansa, Delta, Qatar Airways and Air France-KLM suspended flights to Saudi Arabia and neighbouring states.
On October 13 the Saudi-led coalition struck a fuel facility in Sanaa that it said was used to store missiles and drones; the Yemeni Oil Company said the tanks were empty. Hours later the Houthis hit a Saudi Aramco administrative building in Dhahran, starting a fire with no reported casualties. Saudi Arabia's cabinet warned the group would face "consequences." The humanitarian cost inside Yemen is rising too: the UN says at least 46 civilians have been killed since August and more than 200,000 people displaced since September, according to the same report.
Underneath the military activity sits a negotiation that neither side has abandoned but neither seems ready to close. Vice President JD Vance has called for a "meaningful" reduction in Iran's enrichment capacity, which some experts read as a softening from earlier demands that Iran give up enrichment entirely, Al Jazeera's explainer noted. Iran's late-September proposal would have paired a halt to fighting on all fronts with the lifting of the US naval blockade and oil sanctions, the release of frozen assets and a reopening of Hormuz before nuclear talks. President Trump rejected it.
Tehran now says Washington has accepted some of its seven conditions but that the response remains "insufficient," per Al Jazeera. Featherstone observed that the administration has not re-engaged mediators such as Qatar and Pakistan. That matters: without a trusted channel, each side is left signalling through force, which is exactly what the tanker strikes and airport attacks amount to.
It is impossible to separate this crisis from American politics. President Trump has accused the Houthis of escalating attacks on Saudi infrastructure to push up energy prices before the November midterms, saying they had re-emerged "probably at the behest of Iran," Al Jazeera and Reuters reported. He has also repeated that the US could expand military action after the elections. Critics point to the other side of the ledger: an AP-NORC poll cited in the same report found nearly 70% of voters say the war was not worth fighting, and Democrats are campaigning on its costs. Both narratives can be true at once: adversaries may be timing pressure to the US calendar, and the war's economic fallout is a genuine political liability for the administration.
Meanwhile, the economic stakes are global. The IMF warned this week that world oil stocks are falling by about 2.7 million barrels per day, raising the risk of a sharp price spike, Axios reported. IMF chief Kristalina Georgieva said the attacks on Saudi Arabia could have negative spillover "everywhere," according to Al Jazeera.
The broader point is that the Gulf crisis has shifted from a single-chokepoint problem to a two-front one. Hormuz and Bab al-Mandeb are now linked, and pressure on one is being used to create leverage on the other. Until a diplomatic track is restored, energy markets will remain hostage to the next drone.
