Oil Falls on Flows Still 6.1 Million Barrels Short

Brent crude for November fell 1.66% to $102.15 a barrel on Sept. 21 as traders priced a wartime hole like a recovery. U.S. West Texas Intermediate for October dropped 1.83% to $98.46.

JPMorgan’s commodities desk said in a Sept. 18 note that Middle East oil flows remain “surprisingly strong” with Saudi Arabia’s East-West pipeline out. Those flows averaged 17.1 million barrels a day over 10 days, still 6.1 million a day under the 2025 average, two days after Houthi missiles were fired at Riyadh and claimed against Yanbu.

17.1 Million Barrels a Day Is Still a Hole

The bank’s line is doing a lot of work in the tape. “Surprisingly strong” is a wartime comparison, not a peacetime one, and the same note puts the 10-day average 6.1 million barrels a day below last year’s run rate.

MONDAY’S TAPE AGAINST THE FLOW PRINT

• Brent November: $102.15 a barrel, down 1.66% on Sept. 21.
• WTI October: $98.46 a barrel, down 1.83%.
• Middle East 10-day flows: 17.1 million barrels a day, 6.1 million under the 2025 average, per JPMorgan’s Sept. 18 note.
• Saudi oil through Hormuz: 2.9 million barrels a day over six days of satellite readings, up from 700,000 barrels a day in August.

That Saudi pivot is the piece of the note the market wanted. Satellite readings in the same research showed Saudi barrels moving through the Strait of Hormuz at 2.9 million a day over six days, after August’s 700,000. Analytics firm Kpler’s provisional tally has the kingdom’s total exports back just over 4 million barrels a day so far in September after 2.4 million in August, the lowest since at least 2013.

Four million barrels a day of Saudi exports is a rebound from August. It is also about what the East-West line itself had been moving toward Yanbu before drones forced it closed, which means the “recovery” is a reroute through a contested strait, not spare oil returning from nowhere.

For the first time since the start of Iran conflict, we don’t have a baseline view. We simply don’t know how to model the endgame.

JPMorgan commodities team, Sept. 18 note

The same desk put Brent’s fair value near $90 a barrel against prices then around $106, with about 10 million barrels a day already knocked out and global demand running 4.4 million a day below a year earlier. U.S. gasoline was at $4.37 a gallon in that note, and diesel was at a record $6.31 heading into winter. Brent has averaged $94 since the war began, which is how a market can print a down day at $102.15 and still be living in a shortage.

Saturday’s Missiles Reached Riyadh and Claimed Yanbu

Yemen’s Houthis said on Saturday, Sept. 19, that they had fired a large number of ballistic missiles, cruise missiles, and drones at “sensitive sites” in Riyadh and at Aramco facilities in Yanbu, the Red Sea terminal at the western end of the damaged pipeline. Houthi military spokesman Yahya Saree called the two operations a response to a Saudi attack on Sanaa and said both had caused massive fires.

The Saudi-led coalition said air defences intercepted a ballistic missile aimed at the capital at dawn, the first such claim on Riyadh since this round of fighting widened. Coalition spokesman Maj. Gen. Turki al-Maliki said attempts on civilians and civilian sites in Bisha, Taif, Farasan, and Yanbu were also stopped. Residents heard blasts. Black smoke rose from an Aramco fuel tank near King Khalid International Airport, and flights were delayed or cancelled for a stretch of the morning.

Aramco did not issue a public damage report on the Yanbu claim. The market opened Monday anyway as if the weekend had confirmed the reroute through Hormuz, not as if the export hub at the far end of the shut pipeline had just been named as a target.

A 7.6 Million Barrel Strait That Used to Move 20

U.S. Central Command has been selling a different picture of the same waterway. Adm. Brad Cooper, the command’s leader, said in a Sept. 19 video that crude, cargo, and LNG volumes over the prior two weeks were higher than at any point in the past six months, that more than 1 billion barrels of crude had left the Gulf through Hormuz in recent months, and that U.S. forces had helped more than 2,000 commercial ships across, with Iran exporting zero barrels under the American blockade.

Set that milestone next to the agency prints. The International Energy Agency’s Toril Bosoni, who heads the oil industry and markets division, wrote on Sept. 18 that Hormuz flows averaged only 7.6 million barrels a day in August, 13.1 million below pre-war levels, with cumulative export losses through the strait approaching 2.8 billion barrels. The U.S. Energy Information Administration’s chokepoint table, in the September Short-Term Energy Outlook, puts Hormuz at 21.6 million barrels a day in the fourth quarter of 2025 and at 4.9 million barrels a day in the second quarter of 2026.

EIA OIL FLOWS AT TWO CHOKEPOINTS

Bab el-Mandeb, the southern gate of the Red Sea, is the other number in that table. EIA has those flows up from 5.4 million barrels a day in late 2025 to 8.1 million in the second quarter, which is the Yanbu detour working, until Houthi advances on the Yemeni coast and the East-West outage started to chew on it. An IEA factsheet compiled from 2025 tanker data put nearly 20 million barrels a day in 2025 through Hormuz, about 25% of seaborne oil trade, with 80% of it headed to Asia and only about 3.5 to 5.5 million barrels a day of pipeline capacity able to skip the strait.

WHERE THE HORMUZ COUNTS DISAGREE

• IEA August: 7.6 million barrels a day through Hormuz, 13.1 million below pre-war, in Bosoni’s Sept. 18 commentary.
• EIA second quarter: 4.9 million barrels a day through Hormuz, down from 21.6 million in late 2025.
• Seven-day snapshots: U.S. Energy Secretary Chris Wright has cited about 11 million barrels a day; Clarksons Research has been nearer 8 million. Those are short windows, not quarterly averages, and they still sit well under the 2025 run rate.

Cooper’s billion barrels is a large escort total. Against a strait that used to clear about 20 million barrels a day, it is not a reopened market.

How Producers, Buyers, and Stockpiles Closed the Gap

The reason $102.15 can print as a down day is that the 10-million-barrel hole never showed up one-for-one in inventories. IEA balances put the actual deficit at 2.2 million barrels a day in the second quarter and 1.7 million in the third. The rest was eaten by four offsets that are now getting thinner.

WHAT FILLED THE WAR-SIZED HOLE

• A pre-war surplus: Global supply ran 1.4 million barrels a day above demand in 2025, and more than 2 million a day in the second half, so the war began with fat stocks, much of them in China.
• Bypass ports: Loadings from Yanbu and the UAE’s Fujairah rose from 4.1 million barrels a day in February to 7.8 million in June, then fell back to 5.5 million in August after Houthi attacks in the Red Sea, offsetting more than 500 million barrels, or 2.8 million a day, of lost Hormuz volume before the East-West line was shut in early September.
• Oil from outside the Gulf: Producers beyond the region added a cumulative 420 million barrels, or 2.3 million a day, led by the United States (520,000), Brazil (470,000), Kazakhstan (440,000), Venezuela (300,000), and Nigeria (200,000), with biofuels up a seasonal 890,000.
• Demand that broke: Global oil use over six months ran 5.8 million barrels a day below February, a cumulative cut of more than 1 billion barrels. China accounted for the largest slice, 1.7 million a day below February and 1.1 million below a year earlier, with seaborne crude imports falling from 11.5 million barrels a day in February to 6 million in June.

Second-quarter demand fell 5.3 million barrels a day year on year, the first quarterly drop since Covid, with gasoil down 1.2 million and naphtha, LPG, and ethane down 1.8 million combined. The IEA now expects 2026 demand to contract by 2.5 million barrels a day, 80% of that in the Middle East and Asia. Some Asian governments have gone to rationing. Even after all of that, observed stocks have been drawing at record rates of 2.8 million barrels a day for six months and sit 507 million barrels below the start of the war. IEA member countries have released more than 300 million barrels of emergency oil since the March 11 collective action. Non-OECD crude accounts for 105 million of the draw, 65% of it from tanks in China.

Bosoni’s warning sits under the Monday bid. If Gulf supplies stay tight and those buffers keep draining, higher prices and another round of demand cuts are what close the books, not a one-day fade in Brent.

Saudi Crews Weld a Bypass Around Damaged Pumps

The East-West line, also called Petroline, runs about 1,200 kilometers from the eastern fields around Abqaiq to Yanbu. Aramco raised its stated crude capacity to 7 million barrels a day in March 2025 by converting NGL lines, though sustainable flows at that rate were never really tested. In the war it became the kingdom’s main way around Hormuz. Flows through it had been near 4 million barrels a day, about 4% of global supply, before the shut.

Drones launched from Iraq’s Maysan province hit pump stations in the Riyadh and Medina regions on Sept. 10 and 11. Iraq’s prime minister’s office said the operations commander in Maysan was removed after the launch site was traced. Saudi authorities closed the line as a precaution on Sept. 11. Vantor satellite imagery later showed a pump station burned out through the process area, with crude pooled on the sand past the fence.

U.S. Energy Secretary Chris Wright called the outage short and temporary and said oil would move again within days. People familiar with Aramco’s plan have described a partial restart at about half of recent flow in days, and full repairs in five to eight weeks if the electrics and structures are as bad as they look. Kpler has said a month offline would pull about 120 million barrels from the market. Traders have put remaining export stocks at Yanbu at five to seven days if the pumps stay dark. Later Vantor frames showed crews laying and welding a pair of new lines around a damaged station, a shunt that matches the “half of it back soon” talk and also matches a line that is not actually running.

THE BYPASS THAT STOPPED BEING A BYPASS

1. Feb. 28, 2026: The U.S.-Israeli war on Iran begins and tanker traffic in Hormuz collapses.
2. March 11, 2026: IEA members announce a historic emergency stock release that later exceeds 300 million barrels.
3. June 2026: Yanbu and Fujairah loadings peak at 7.8 million barrels a day.
4. August 2026: Houthi attacks in the Red Sea cut those bypass loadings to 5.5 million; Hormuz averages 7.6 million.
5. Sept. 10-11, 2026: Drones from Iraqi territory hit East-West pump stations; Saudi Arabia shuts the line.
6. Sept. 19, 2026: Houthis fire on Riyadh and claim an Aramco hit at Yanbu; Cooper says Hormuz volumes are at a six-month high.
7. Sept. 21, 2026: Brent settles the session 1.66% lower at $102.15.

European cargoes out of Yanbu were cancelled or deferred after the shut. Saudi barrels have been offered instead as ship-to-ship transfers off Oman’s Sohar port, shuttled through Hormuz under U.S. escort and loaded onto waiting hulls in the Gulf of Oman. That is the 2.9 million-barrel Saudi Hormuz print. It is also a bet that Iran, and the Houthis at the other end of the Red Sea, let that shuttle keep running.

Trump’s Deciding Mode and a Billion-Barrel Escort

President Donald Trump said he is in a “deciding mode” and that “very big things” are coming on the U.S.-Iran war. “My question is, if and when do I blow the entire nation up? They better behave,” he said. In a separate interview he put the choice as whether to “annihilate” the Iranian government or not. He has also said he would be open to meeting Iranian President Masoud Pezeshkian, who is due in New York for the U.N. General Assembly.

The White House did not join Saudi strikes against the Houthis over the weekend. That leaves the kingdom fighting a second front in Yemen, with the Bab el-Mandeb under Houthi pressure and the East-West line still dark, while U.S. ships keep walking tankers through Hormuz. Cooper’s update is the public face of that escort.

Update from CENTCOM Commander: pic.twitter.com/PTX6n9fn56

— U.S. Central Command (@CENTCOM) September 19, 2026

Daniel Takieddine, co-founder and chief executive of Sky Links Capital Group, has the prices tied to how fast exports look normal and how the diplomacy reads, not to a single down session. The Monday bid is a wager that Wright’s “few days,” Aramco’s welded shunt, and Cooper’s six-month high are the path, and that Trump’s deciding mode stays in the interview chair.

Diesel at $6.31 Meets a 507 Million Barrel Draw

Crude can fade on a reroute. Diesel does not care about the story the futures pit tells itself. JPMorgan had U.S. diesel at $6.31 a gallon, an all-time high, with inventories at record lows into the season when heating and freight usually take more barrels, not fewer. Jet fuel in Singapore has been part of the same squeeze. Rapidan Energy has put the pipeline outage at about 400,000 barrels a day of lost Saudi crude this month, with the risk skewed larger if the line stays down past September or if Iran, the Houthis, or allied groups hit shipping again.

Any setback or renewed deterioration in shipping conditions would tighten the physical market and restore upward pressure on prices.

Observed oil stocks are already 507 million barrels lighter than they were when the war started, and the IEA has them still drawing at 2.8 million barrels a day. The East-West pumps are not moving oil. Saturday’s missiles were aimed at the capital and at the terminal that was supposed to replace Hormuz. Monday’s $102.15 is what a market looks like when it decides all of that is already in the price.
