Oil markets continued their downward spiral on Friday, with both major benchmarks extending losses into a third consecutive session as traders grappled with mounting concerns over global supply increases and softening demand fundamentals.
Brent crude futures, the international benchmark, dropped 19 cents to $66.80 per barrel by mid-morning GMT, representing a 0.28% decline. Meanwhile, U.S. West Texas Intermediate crude fell more sharply, shedding 23 cents, or 0.36%, to settle at $63.25 per barrel. The sell-off has resulted in Brent posting a 1.92% weekly decline and WTI down 1.19% for the week—marking the first weekly losses for both benchmarks in three weeks.
OPEC+ Supply Surge Looms Large
The primary catalyst driving the market downturn centers on growing expectations that the OPEC+ alliance will flood the market with additional barrels in a bid to reclaim market share lost to U.S. shale producers over recent years. ANZ research analysts highlighted this concern in their Friday market note, pointing to the cartel’s apparent shift from production discipline to market share competition.
The anticipation reached fever pitch following Reuters reports on Wednesday that eight OPEC+ members, including major producers alongside Russia, are actively considering further production increases as early as October. Sources familiar with the discussions indicated the group will deliberate this move during Sunday’s critical meeting.
Such an increase would represent a significant acceleration of the alliance’s supply strategy. OPEC+, which controls approximately half of global oil production, would effectively begin unwinding its second layer of output cuts—totaling 1.65 million barrels per day, or roughly 1.6% of world demand—more than a year ahead of the originally planned schedule.
U.S. Inventory Build Compounds Concerns
Adding to the bearish sentiment, U.S. crude inventories posted an unexpected build of 2.4 million barrels last week, according to Energy Information Administration data released Thursday. The increase caught analysts off guard, with market consensus anticipating a 2-million-barrel draw instead.
The inventory build comes as U.S. refineries enter their traditional autumn maintenance season, typically a period when crude demand from the downstream sector weakens considerably. BMI analysts warned that refining margins face additional pressure in the coming months as global demand growth continues to decelerate and maintenance activities intensify across the sector.
“Strength in the downstream sector has been a key support for prices over recent months,” BMI analysts noted in their latest report. However, they cautioned that reduced refinery throughput will inevitably “lower the call on crude,” further dampening demand prospects.
Geopolitical Wild Card Remains
Despite the prevailing bearish fundamentals, supply risk factors continue to inject volatility into market sentiment. President Donald Trump‘s directive to European leaders on Thursday, demanding they cease Russian oil purchases, introduces a potentially significant supply disruption element.
Any meaningful reduction in Russian crude exports—or alternative supply disruptions—could rapidly reverse the current price trajectory, analysts warn. Russia remains a crucial supplier to global markets, and any sustained interruption to its export flows would likely trigger sharp price increases.
The juxtaposition of abundant supply expectations against persistent geopolitical risks highlights the complex dynamics currently governing oil markets, leaving traders navigating between competing fundamental forces as the energy sector enters the typically volatile autumn period.
Market participants will closely monitor Sunday’s OPEC+ meeting for definitive signals on production policy while keeping a watchful eye on any developments regarding Russian supply flows and broader geopolitical tensions that could reshape the supply-demand equation.
WHAT YOU SHOULD KNOW
Oil prices fell for the third straight day on Friday, with Brent at $66.80 and WTI at $63.25, marking their first weekly decline in three weeks. The primary driver is growing expectations that OPEC+ will significantly increase oil production as early as October to reclaim market share from U.S. shale producers—potentially unwinding 1.65 million barrels per day of cuts more than a year ahead of schedule.
This supply surge threat, combined with an unexpected 2.4 million barrel build in U.S. crude inventories and weakening refinery demand during maintenance season, has overwhelmed market sentiment despite ongoing geopolitical risks from potential Russian supply disruptions.
