Key Takeaways:
Brent crude slid more than $1 a barrel as forecasters slashed 2026 global demand projections, even as deadlocked US-Iran talks kept a floor under prices.
Brent crude fell $1.29, or 1.5%, to $87.69 a barrel by 0100 GMT, while US West Texas Intermediate dropped $1.30, or 1.6%, to $81.97, after the Organization of the Petroleum Exporting Countries and the International Energy Agency both cut their 2026 global demand forecasts on Wednesday.
"The safety situation for navigation in these waters has further deteriorated, forcing vessels to turn off their signals, which reduces transparency in shipping and makes it more difficult for the market to track and assess actual supply levels," analysts at Haitong Futures said in a note.
OPEC lowered its world oil demand growth forecast for 2026 to 580,000 barrels per day in its monthly oil market report. The IEA expects a 1.6 million bpd contraction in consumption this year, down from a 1 million bpd forecast last month, because restricted fuel supplies and higher prices from the US-Israeli war on Iran have curtailed demand. Prices also came under pressure from a surprise build in US commercial crude inventories, which posted their largest weekly gain since January 2023 as exports slumped. Crude inventories rose 17.4 million barrels to 424.4 million barrels in the week ended August 7, their highest since June 5, the Energy Information Administration said, versus analysts' expectations for a 1.4 million-barrel draw.
The deadlocked talks between Iran and the US to end the war in the Gulf have kept prices elevated. A senior Iranian source said Wednesday there had been no progress in talks to revive the interim deal agreed in June and define a time frame to implement it. Attacks on shipping in the Strait of Hormuz and the Bab el-Mandeb Strait on Tuesday, two crucial export routes for Middle Eastern oil and gas, highlight the risks that remain for crude supply from the region.
The IEA also predicts a 4.3 million bpd drop in supply this year and an overall 2026 deficit of around 1.27 million bpd, according to the agency's latest projections. Shipping data showed the number of vessels transiting Hormuz fell to a one-week low of eight on Tuesday, down from the 125 to 140 that passed through the crucial waterway daily before the war. The last time US crude inventories posted a weekly build of this magnitude was in January 2023, when a similar export slump coincided with a seasonal demand trough.
For energy producers and refiners, the divergence between falling consumption and constrained supply points to sustained price swings through the fourth quarter. If the deadlock persists, the market faces a widening gap between a demand contraction and a supply shortfall that keeps prices volatile, with the next OPEC+ meeting and any movement in US-Iran negotiations serving as the key catalysts. A breakthrough in talks would likely ease the supply premium, while a further escalation in the Strait of Hormuz could push Brent back toward $90 and beyond.
