Brent Holds Above $100 as Diesel Already Hits $5.94

Brent crude held above $100 a barrel on Thursday after the United States and Iran traded strikes on shipping around the Strait of Hormuz. By 0107 GMT the contract was at $101.34, up 0.1%, while West Texas Intermediate traded at $96.55, up 0.5%.

Wednesday’s settle was the print that crossed the line. Brent closed at $101.21, up $3.29 or 3.4%, after a high of $101.58. WTI rose $3.02, or 3.25%, to $96.05. Both were the highest finishes since May 22. The futures tape was late. Dated Brent, the physical grade used to price about two-thirds of the world’s oil, has been above $100 since September 3, LSEG data show, and U.S. drivers were already paying record diesel.

Dated Brent Had Already Cleared $100

Oil had mostly stayed below $100 from late May as traders treated the war that began on February 28 as contained. A mid-June halt in attacks helped that bet. Brent had spiked as high as $126.41 on April 30, then briefly crossed $100 again in late July before slipping back. The September push is smaller than that spring peak. It is landing on a market that already lost its buffer.

THE PRICE STACK BEHIND $100 BRENT

The $5.16 gap between Wednesday’s Brent and WTI closes is the Atlantic Basin still clearing more easily than barrels that have to leave the Gulf. That spread does not soften the bill at the pump. AAA’s national gasoline average on September 8 was $4.22 a gallon, up 1.9% on the day. Diesel was $5.94, up 1.0%, and closing in on $6.

Asian stocks fell on Thursday with oil still above $100, adding a risk-off layer ahead of U.S. inflation figures due Friday. The crude headline is what screens catch. The fuel print is what households and freight already paid.

Five Tankers Went Down Near Kharg Island

U.S. Central Command said its forces destroyed five Iranian crude oil carriers on September 8 after Iran’s Islamic Revolutionary Guard Corps fired ballistic missiles at a U.S. Navy warship twice over two days. The warship evaded both attempts, the command said, and no American personnel were harmed. Crews were told to abandon ship before the vessels were hit.

Iran has used the tankers as part of a multibillion-dollar shadow network that funds the IRGC and its regional proxies. Iran has no means by which to defend these vessels.

U.S. Central Command, September 8 public release

The five ships named on September 8 were M/T Kaviz, M/T Charminar, M/T Horizon 1 and M/T Riesco in the Gulf of Oman, plus M/T Derya near Kharg Island, Iran’s main crude-export hub. On September 5, CENTCOM said it had destroyed three other Iranian crude carriers after the Guard tried to hit a U.S. aircraft carrier and a guided-missile destroyer. That is eight tankers in the command’s own account in four days. Washington has framed the hits as a standing reply whenever fire threatens U.S. warships.

Iran’s Guard said it then attacked 10 ships near the strait, including two U.S. vessels and eight oil tankers, and fired ballistic missiles at a U.S. base in Jordan. U.S. Central Command said the attempted attacks on American ships failed. Jordan said it intercepted 18 missiles, with the other two falling in unpopulated areas. Peninsula, the charterer of the oil-products tanker Hercules Star, said one seafarer was killed at anchorage off Dubai and another was missing.

WHAT WE KNOW

• U.S. tanker tally: CENTCOM says it destroyed three Iranian crude carriers on September 5 and five on September 8, and that crews were ordered off before the later strikes.
• Iran’s claim: The Guard said it hit 10 ships near Hormuz, two of them American, and that it would answer two or three enemy strikes by hitting 20 targets.
• The human cost: Peninsula said one crew member on Hercules Star was killed and another was missing.

WHAT IS UNCONFIRMED

• U.S. hulls: Tehran said two American vessels were struck. The U.S. command said every attempt on its warships failed.
• The new exclusion map: The Guard said it would publish a larger off-limits zone reaching as far as Chabahar, near Pakistan. The chart has not been issued as a settled rule of the sea.

Marco Rubio, the U.S. secretary of state, put the American rule in one line: Iran keeps trying to hit U.S. naval ships, and each time it does, or tries to, it will lose tankers. The Guard’s reply was volume. If the enemy struck two or three Iranian targets, it would hit 20. That is a shipping war sitting on top of an oil war, and it is why $100 futures finally printed after Dated Brent had already moved.

THE WEEK THE SHIPS WERE HIT

1. September 5: CENTCOM says it destroys three Iranian crude oil carriers after the Guard tries to attack a U.S. aircraft carrier and a destroyer.
2. September 8: After two ballistic-missile attempts on a U.S. warship, U.S. forces hit five named Iranian crude carriers, including Derya near Kharg Island.
3. September 9: The Guard says it attacked 10 ships near Hormuz and fired on a U.S. base in Jordan; Brent settles at $101.21, the highest close since May 22.
4. September 10: Brent holds at $101.34 by 0107 GMT, with WTI at $96.55, as Asian stocks fall.

Nearly one-fifth of the world’s oil used to move through Hormuz before the war. Flows have stayed well below that for months. Attacks on the ships that still try the passage now hit a thinner stream, which is why each burning hull moves the price more than the old one-in-five cliché implies.

Supply Is Forecast to Fall 4.3 Million Barrels a Day

The International Energy Agency’s August Oil Market Report had already marked the hole the futures market is now pricing. Global supply is projected to fall by 4.3 million barrels a day in 2026, to 102 million, about 4% of the prior base. Growth of 1.4 million barrels a day from the Americas only partly offsets losses in the Middle East and Russia. Demand is forecast to shrink by 1.6 million barrels a day as closed waterways and high fuel prices cut use. The agency sees a rebound of 8.3 million barrels a day in 2027, to 110.3 million, if the routes reopen.

IEA AUGUST BALANCE

• Gulf output: Production rose 2.5 million barrels a day in July to 23.9 million and was still 8.3 million below pre-war levels.
• Loadings: Regional exports, including bypass routes, fell 2.1 million barrels a day to 15 million after Hormuz was effectively closed again in early July; loadings peaked at 20 million at the start of the month and dropped to about 12 million later.
• Stocks: Observed inventories fell 69 million barrels in July and were down 410 million barrels from the start of the war, averaging 2.7 million barrels a day, to just below 7.9 billion barrels.
• The gap: The third-quarter balance is a deficit of 1.8 million barrels a day, more than double the prior month’s estimate of about 800,000.

Refinery crude runs in July were 80.9 million barrels a day, still nearly 5 million below a year earlier. Seaborne product trade was down 3.8 million barrels a day year on year. Diesel exports from Russia, the Middle East and Asia were 1.3 million barrels a day lower, about 20% of global seaborne diesel trade. Jet-fuel exports from those regions were down about 670,000 barrels a day, equal to 34% of that trade. U.S. product exports rose 700,000 barrels a day, which is a relief valve for the Atlantic and a reminder that the shortage is in middle distillates leaving the Gulf, not in every barrel everywhere.

With an agreement enabling the reopening of Hormuz and unhindered transit through the Bab el-Mandeb Strait still elusive, we have again lowered supply estimates for the rest of the year.

International Energy Agency, August 2026 Oil Market Report

North Sea Dated rose $25.67 a barrel over July to $96.80 at month-end, and prices spiked as high as $105 on July 23 after the mid-June halt broke down. Benchmark crudes swung through a range of almost $40 a barrel that month. The September close above $100 is inside that band. The stock draw is not. Once 410 million barrels are gone, a fresh week of tanker fires does not need a $126 print to tighten diesel.

Record Diesel Prices Are Doing the Inflation Work

The U.S. Energy Information Administration’s daily sheet for the September 8 close put AAA’s national diesel averaging $5.94 a gallon and regular gasoline at $4.22. Wholesale low-sulfur diesel was $4.64 a gallon in New York Harbor and on the Gulf Coast, and $5.13 in Los Angeles. Heating oil in New York Harbor was $4.54. Those are the fuels that move trucks, ships, and harvests. Crude can sit in a tank. Diesel has to be made, then shipped, and both steps have been cut.

The IEA said Atlantic Basin refining margins hit all-time highs in July as diesel, jet, and gasoline cracks jumped on thin stocks and seasonal demand. Capacity elsewhere has not filled the hole left by Middle East product exports and attacks on Russian plants. That is why pump prices can stay high even when paper Brent dips below a round number, and why they jump when it recaptures one.

THE FUEL MARKET AHEAD OF CRUDE

• Physical crude: Dated Brent has held above $100 since September 3, a week before the futures close that made the screens.
• U.S. distillate stocks: The EIA’s September outlook, with inputs closed on September 3, already had distillate stocks falling below 100 million barrels in September and staying under the 2021-2025 low through much of 2027.
• The annual math: That same outlook raised its 2026 retail diesel average to $5.07 a gallon from $4.85, a 4.4% upgrade, and still sits well below the $5.94 AAA print already on the board.
• The freeze date: The EIA said the September forecast does not account for market events after September 3, which means this week’s tanker exchange is not inside the $91 Brent average or the $3.84 gasoline average it still carries for 2026.

Global oil inventories have fallen about 400 million barrels this year in the EIA’s tally, close to the IEA’s 410 million barrels of observed draws since the war began, and the U.S. agency expects further declines through year-end. It has Brent averaging about $90 in the second half of 2026 and $74 in 2027, with Middle East output still below pre-conflict averages until the second quarter of 2027. Those are calm yearly means against a $101 handle and $5.94 diesel. U.S. crude output is still projected at 13.8 million barrels a day in 2026, up from 13.7 million in 2025, which helps the Atlantic and does not refill Hormuz.

The June Halt Did Not Reopen Hormuz

Traders had a reason to fade $100. In mid-June the United States and Iran reached an interim halt, and prices slid as loadings from the Gulf started to rebuild. Shipments through the strait, aided by ship-to-ship transfers in the Gulf of Oman, lifted from a May low near 9.6 million barrels a day toward about 12 million. The IEA’s August report says Gulf production then rose 3.7 million barrels a day in June and another 2.5 million in July, to 23.9 million, before the passageway was effectively closed again in early July and infrastructure and tankers came back under fire.

No lasting deal followed the June pause. Hostilities resumed, and July prices whipped from hopes of a reopening to that $105 spike on July 23. Loadings that had touched 20 million barrels a day at the start of July fell to about 12 million later in the month. Bab el-Mandeb, the Red Sea gate, stayed a second chokepoint. The September tanker-for-tanker week is that unfinished halt arriving as policy: the United States sinks Iranian crude carriers when its warships are shot at, and the Guard answers on commercial hulls and a Jordanian base.

The IEA still writes the 2027 rebound as 8.3 million barrels a day, to 110.3 million, which only works if Hormuz and Bab el-Mandeb function. Until then the Americas’ 1.4 million barrels a day of extra supply is the relief that exists, not the relief the import system was built around. Refiners that can get Atlantic crude are running the cracks. Fleets that need diesel are paying $5.94.

Gasoline at $4.22 Meets the August CPI Print

The Bureau of Labor Statistics will publish the August consumer-price index on Friday, September 11, at 8:30 a.m. Eastern. July’s all-items index was up 3.4% from a year earlier. Energy in that report was up 14.7% year on year, even after a 1.5% drop on the month, with gasoline still up 24.6% from a year earlier. A $4.22 gasoline average and $5.94 diesel do not walk into that print quietly, and they feed the next one after that.

Higher crude can lift gasoline, diesel, and jet fuel together, which raises the cost of moving food, parts, and people. That is the second bill inside the $101.21 settle. Paper oil is a screen. Diesel is freight. The IEA has already cut demand by 1.6 million barrels a day because those fuel prices, and the missing barrels behind them, are forcing users to stop. That demand drop has not closed the 1.8 million-barrel third-quarter gap. It has only kept the deficit from being larger.

The EIA’s $91 average for 2026 still assumes some Gulf barrels return along Hormuz and the bypass lines, with constraints lasting through December. Its own note says events after September 3 are outside the model. Five named tankers went down on September 8. Iran said it hit 10 ships the next day. Dated Brent had been above $100 since September 3. U.S. diesel was $5.94 before the futures close that made the headline. Friday’s CPI will measure how much of that fuel bill is already in the official basket, not whether Hormuz is open.

Brent can hold $101.34 and still be the lagging number. The leading ones are the 410 million barrels already gone, the 12 million-barrel loading rate the IEA last counted out of the Gulf, and a national diesel average that has not waited for paper crude to catch up.
