The Surplus Is Real, and Mostly Afloat

The International Energy Agency has declared the oil market in surplus. The country's onshore storage tanks have not got the message.

In its monthly report, the IEA said global oil markets will swing to a supply surplus for the first time since the start of the Iran war, as Persian Gulf exports recover despite the ongoing conflict, Rigzone reported, relaying Bloomberg. The agency said the market "is showing tentative signs of rebalancing." Bloomberg put the overhang at roughly 2 million barrels a day this quarter, against a deficit of similar size projected a month ago. Reuters, in a report carried by CP24, said fourth-quarter supply will average 105 million barrels per day, 1.7 million bpd above forecast demand. Benchmark crude is down about 18 percent this month, Bloomberg said.

That is a large turn in a month. It is also a surplus with an asterisk, and the asterisk is where the money is.

Barrels at sea

Start with where the oil is. The IEA said observed inventories rose in October for the first time since June. Bloomberg reported that the build was dominated by barrels at sea, while onshore stockpiles stayed at their lowest in a decade. A surplus on tankers in transit can be refined, burned or sold. It cannot yet cushion a refinery that is running short.

The US picture fits. US commercial crude inventories fell by 14.1 million bbl in October to about 410 million bbl, the lowest end-of-October level since 2014, Oil & Gas Journal reported, citing the EIA. A weekly bounce followed: Oil & Gas 360, citing EIA data, said commercial crude rose by 4.7 million barrels in the week ending November 6, 2026, to 414.4 million barrels. That still leaves stocks 4% below the five-year average for this time of year.

The Gulf recovery behind the surplus is real but improvised. Exports have rebounded to 74 percent of pre-war levels on a surge from Saudi Arabia and Iraq, the IEA said, even as tankers keep coming under attack. Saudi Arabia raised crude output to 10 million barrels a day in October, and Iraq reached a seven-year high of 4.6 million a day, per the IEA. Saudi Arabia told OPEC it pumped 10.56 million bpd in October, its highest level since February, Arab News reported, relaying Asharq Al-Awsat.

Reuters reported that Gulf producers are getting oil out through workarounds, including so-called dark crossings of the Strait of Hormuz, where tankers switch off their tracking signals to evade attack. InvestingLive, relaying a Wall Street Journal report, said confirmed Hormuz transits averaged about 4 million barrels a day over the past week, against roughly 17 million before the conflict, per Kpler data.

Buyers are being paid to take the risk. Saudi Aramco cut its December official selling price for Arab Light to Asia by $2 a barrel, to a $7 discount to the Oman/Dubai benchmark, InvestingLive reported.

A forecast that lags the tape

Washington's own outlook has not caught up with the drop. The EIA's November Short-Term Energy Outlook expects Brent to average about $100/bbl in November and December, Oil & Gas Journal reported. Reuters, in a Yahoo Finance report, put Brent futures at $95.54 on Nov. 13 after a 28-cent fall, headed for a second weekly decline. The agency's October number explains the gap. Brent averaged $124/bbl that month, the highest monthly average since July 2022 on an inflation-adjusted basis, per Oil & Gas Journal's summary.

The EIA does see the surplus coming, just later. It projects stock builds accelerating to an average 3.5 million b/d in the first half of 2027, pushing Brent below $90/bbl in the second quarter. Meanwhile it raised its 2027 retail diesel forecast by 12% to $5.03/gal. Diesel is where the tightness bites, and the IEA's emergency-stock plan reflects it. Reuters said members will make 71 million barrels available by the end of February, including 15 million barrels of diesel, which the agency described as a record release.

The demand side helps explain the IEA's confidence. Reuters reported that world demand is forecast to fall by 2.7 million bpd in 2026 to 102.3 million bpd, and that high prices have curbed consumption and helped tip the balance into surplus. A surplus built partly on rationed demand lasts only as long as prices stay painful.

Tankers still burn

The attacks have not stopped. Iran's military said on Thursday that four oil tankers were hit by explosions in the Strait of Hormuz after ignoring warnings, Reuters reported, adding that it could not immediately verify the Iranian accounts. On Friday, Iran's Revolutionary Guards navy said an LNG tanker struck a naval mine while on what it called an "unauthorised and dangerous route," Reuters reported, citing state media. Reuters also noted that 37 attacks in October were the highest monthly tally since the conflict began in late February, per Washington Institute for Near East Policy data, and at least 10 ships were hit in the first 10 days of November.

The market noticed. January Brent futures advanced 3.30%, settling at $95.82/bbl on Thursday, per market data. Reuters said Yemen's Houthis claimed attacks on a pumping station on the Saudi East-West pipeline, an oil facility in Yanbu and an Aramco building in Riyadh. President Donald Trump said on Truth Social that a deal with Iran was not necessary to end the war, now in its ninth month.

Gas shows the same fragility. European and Asian benchmark gas futures averaged more than $28/MMbtu in October, their highest since December 2022, as tanker attacks constrained LNG shipments through Hormuz, per Oil & Gas Journal. US gas is the contrast: Oil & Gas Journal reported that Henry Hub spot prices are forecast to average $2.87/MMbtu from November through March, 36% lower than last winter.

The next test

The IEA's surplus rests on three things: Gulf barrels that keep finding a way through, demand that stays suppressed, and tankers that keep getting through. OPEC+ meets online on Nov. 29 to discuss next year's output targets, Arab News reported. Producers will be setting quotas for a market whose extra oil is still afloat, still dark-crossing and still under fire.
