Saudi Barrels Fill the Gap as Iran’s Oil Runs Out

Middle East crude exports rose to 16.328 million barrels a day in September, the highest monthly total since the Iran war began on February 28. Ship-tracker Kpler logged the rebound as Saudi Arabia and the United Arab Emirates pushed more cargoes through the Strait of Hormuz and around it.

The gain did not restore a peacetime market. It moved barrels toward Gulf producers that can still sail, and away from Iran, which cannot.

Middle East Crude Hit Its Highest Level Since February

Kpler’s September count covers Saudi Arabia, the United Arab Emirates, Iraq, Oman, Qatar, Kuwait and Iran. It includes transits of the strait, ship-to-ship transfers in the Gulf of Oman, loadings at Fujairah and Oman outside Hormuz, and Red Sea liftings. The same basket stood at 19.513 million barrels a day in February, leaving a gap of about 3.2 million barrels a day.

The figures leave out ships that crossed with their Automatic Identification System transponders switched off. That dark traffic is the main reason other desks print higher totals. It does not change the direction of the month: more Gulf crude got out, and Iran’s share of that flow kept shrinking.

SEPTEMBER EXPORT TALLY

Before the war, the strait typically handled about 125 large commercial vessels a day and about 20% of the world’s daily crude and LNG. Columbia University’s Center on Global Energy Policy has called the halt that followed the largest volumetric supply shock in modern markets, a cut that once took out roughly 15 million barrels a day of crude and 5 million of products through the waterway.

Matt Smith, Kpler’s director of commodity research, said production still needs to rise and refineries still need to ramp back up, and that this cannot fully happen until the safety risk of crossing the strait has been completely removed.

Saudi Arabia Sent the Oil Back Through Hormuz

Saudi Arabia, the region’s top exporter, was on track to ship about 5.4 million barrels a day in September, more than double August’s 2.446 million. That jump is the core of the monthly rebound, and it came after the kingdom’s favorite workaround failed.

Drone strikes from Iraq earlier in September damaged the East-West pipeline that carries crude across the desert to Yanbu on the Red Sea. Aramco then pushed more oil back to Gulf terminals and out through Hormuz, the route Iran had spent seven months trying to choke. Ras Tanura loadings rose to 3.25 million barrels a day from 929,000 in August, still far below the 6.411 million recorded there in February.

Kpler counted 19 very large crude carriers, each carrying 2 million barrels of Saudi oil, leaving Hormuz in a single week in late September, 38 million barrels on that run alone. JPMorgan later said Saudi Arabia had restored about half the East-West pipeline’s flows after the repairs, and tanker loadings at Yanbu resumed. Gulf officials still describe those desert and Red Sea routes as temporary, expensive, and easy to hit again.

The U.S. Energy Information Administration, in its chokepoints review, puts Saudi and UAE pipelines at about 4.7 million barrels of bypass capacity in a full closure. September showed the limit of that math. When the bypass is attacked, the extra Saudi barrels go back into the strait, which is why a damaged pipeline and a record-since-February export month can be the same story.

Almost Nothing Left for Tehran to Sell

Iran has been unable to move newly loaded crude through Hormuz since the United States put its maritime blockade of Iranian ports back in place in July. Prewar exports were nearly 2 million barrels a day. Seaborne sales now sit near 200,000 barrels a day, less than a tenth of that pace, with no pipeline of Saudi scale to go around the American picket.

IRAN’S REMAINING OUTLETS

• Hormuz liftings: Newly loaded Iranian crude stays trapped behind the U.S. blockade at the mouth of the Gulf.
• Oil already at sea: Volumes on vessels outside the blockade have fallen to around 15 million barrels from 29 million in early September, a 14 million-barrel draw, most of it headed for China.
• Trucks: Analysts put overland movements at no more than 40,000 barrels a day, a sliver of the old seaborne trade.
• A seven-day opening: President Donald Trump on September 26 rejected an Iranian plan, passed through Qatari mediators, that would have opened Hormuz and lifted the blockade for a week of talks.

Kpler expects those floating barrels to be gone by early to mid-October at the current pace. Treasury Secretary Scott Bessent said Sunday that Iran would probably make its final deliveries to China within the next two weeks, “and then they will have nothing.”

Iranian parliament speaker Mohammad Bagher Ghalibaf, on state radio, put the regime’s line in one sentence: “In a region where Iran cannot sell oil, no one else will sell oil either.” September’s loadings from Ras Tanura say otherwise. The barrels that left were Saudi and Emirati, not Iranian, and they left while Tehran’s own tanks offshore were emptying.

Three Tallies Put the Rebound at Very Different Totals

Kpler is not the only desk counting. The spread among them is wide because each treats dark ships, products, and weekly versus monthly windows differently. None of the prints is a full return to a safe peacetime strait.

WHERE THE TALLIES DIVERGE

• Kpler, September month: Tracked crude from the seven producers at 16.328 million barrels a day, about 3.2 million short of February, with transponders-off ships excluded.
• JPMorgan, late September: Crude at 17.5 million barrels a day, or 98% of prewar levels, and fuels such as diesel and gasoline at 3 million barrels a day, or 58%; Hormuz flows almost back to late-June highs of nearly 13 million barrels a day.
• Goldman Sachs, last week: Gulf oil including clandestine “dark” cargoes at 23.3 million barrels a day, in line with the 2025 average, with the global market “roughly balanced” in September.

Natasha Kaneva and colleagues at JPMorgan, in a September 29 note, called it a recovery for a region still at war and then drew the line the other desks keep blurring.

The Middle East’s oil export arteries are flowing again. But higher crossings should not be mistaken for improved safety, rather, they reflect the industry’s increasing ability to operate under sustained risk.

Goldman’s Yulia Zhestkova Grigsby wrote that Saudi estimated exports more than doubled in September and rose above their 2025 average, and that the firm still worried about a new strike on energy plants. Front-month Brent for November traded at $103.43 a barrel at 11:40 a.m. in Singapore on September 30, up 0.8%, and was on course for a third monthly gain of about 14%.

That price sits on a market that already learned, in the second quarter, how fast a rumor of a reopening can unwind. Brent began the second quarter above $100 a barrel, then slipped after a June 17 memorandum of understanding that was supposed to resume traffic, then jumped again when fighting resumed. Crude getting out is not the same as crude getting out cheap.

Why Fuel and Gas Still Have Not Followed Crude

The crude rebound is the easy number to celebrate. The harder one is what has not come back. JPMorgan’s 58% reading on products means diesel and gasoline are still the short side of this war, which is why a doubled Saudi export month has not produced a cheap fill-up.

Qatar, which has no export route that skips Hormuz, is the cleanest test of that lag. Several Qatar-linked LNG tankers crossed in September after no visible crossings in August, including GasLog Skagen, later spotted off Sri Lanka with a Ras Laffan cargo. Normal service has not resumed.

QATAR’S WAR CARGOES

• First six months: Qatar exported 18 LNG cargoes against 509 in the same stretch of the previous year, according to data firm ICIS.
• Italy: Edison said QatarEnergy extended force majeure to early December, taking missed cargoes since April to 35, of which 23 were replaced, mainly with U.S. gas; the long-term contract is 6.4 billion cubic meters a year, about 10% of Italian demand.
• South Asia: Customers in Pakistan and Bangladesh were told suspensions run through November.
• Plant damage: Attacks on Ras Laffan cut production capacity by about 17%. Energy Minister Saad Sherida Al-Kaabi said full repairs would take around three years, though 12 units could run normally within weeks if regular passage returned.

Al-Kaabi also said a pipeline around the strait would not pay, because Qatar would still need a new plant outside the country to turn piped gas into LNG. Crude can take a desert line to Yanbu. Qatari gas cannot. That is the split inside the “Middle East exports are back” headline: oil tankers found a way, and a lot of the fuel that actually runs trucks and power plants did not.

OPEC Meets on October 4 With Quotas on Hold

The seven OPEC+ countries that hold extra voluntary cuts (Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria and Oman) already voted on September 6 to keep October production at September levels. Saudi Arabia’s required output for October is 10.478 million barrels a day, a production cap, not an export count. They meet again on October 4.

Holding the line while Saudi seaborne liftings have only just clawed back to about 5.4 million barrels a day is a bet that the war, not the quota table, is still setting the price. Hamad Hussain, a senior economist at Capital Economics, said that without a decisive end to the conflict, the balance of risks to oil prices stays skewed to the upside.

The U.K. Maritime Trade Operations office, tied to the Royal Navy, reported on Sunday that no confirmed attacks or disruptions had occurred in Hormuz during the preceding 72 hours, with the last listed strike on September 23. A quiet weekend is not a settled strait. Richard Bronze, co-founder of Energy Aspects, said that if Iran’s leadership feels its control over Hormuz is weakening, the risk rises that it will look for other ways to escalate.

Sanam Vakil, director of the Middle East program at Chatham House, made the same point from the other side of the table, as Gulf loadings rose and Iranian revenue fell.

It shows the diminishing returns of Iran’s Hormuz approach. That could lead to a more explosive dynamic where they will have to provoke or press the go button on a larger conflict themselves in order to get out of this bind.

Ayatollah Mojtaba Khamenei, named as successor after his father was killed on February 28 and still unseen in public, referred in a Monday statement to “the defenders of the Strait of Hormuz.” The U.S. Navy and Gulf terminals have spent seven months learning to move oil under that threat. Iran has spent the same stretch watching other people’s tankers leave.

Bessent’s clock runs to mid-October. Kpler’s floating inventory runs out on the same window. Until those last Iranian cargoes are gone, Tehran still cashes a shrinking set of Chinese barrels. After that, the only leverage left in the strait is the ability to hit someone else’s.
