Oil rises 1% after fire at US refinery, set to snap four-session losing streak

Oil prices rose 1% on Friday after a fire at Chevron's 290,000 bpd El Segundo refinery on the U.S. West Coast. However, crude benchmarks are still poised for their steepest weekly decline since late June, down approximately 7%, driven by market expectations that OPEC+ could increase output by up to 500,000 barrels per day in November. This anticipated supply surge, coupled with slowing global refinery activity and seasonal demand weakness, is projected to create a significant oil market surplus by Q4 2025 and beyond, potentially driving prices further down.

Analysis

Oil prices experienced a transient 1% increase in response to a fire at Chevron's 290,000 bpd El Segundo refinery, a significant facility on the U.S. West Coast. This short-term supply disruption, however, is overshadowed by a strongly bearish weekly trend, with both Brent and WTI crudes on track for their steepest weekly decline since late June, falling approximately 7.6% and 7% respectively. The primary driver of this negative sentiment is mounting market expectation that OPEC+ will increase output by as much as 500,000 barrels per day in November. This potential supply injection, combined with slowing global refinery activity, a seasonal dip in demand, and rising U.S. inventories confirmed by the latest EIA report, points toward a fundamental oversupply. Supporting this outlook, JPMorgan analysts have identified September as a turning point, forecasting the market is heading towards a 'sizeable surplus' in Q4 2025 and into the following year, while IG analysts project a 500,000 bpd OPEC+ hike could push crude prices down to test lows around $55.00 per barrel.

Key Decisions for Investors

• Investors should recognize that the bearish macro-outlook, driven by potential OPEC+ production hikes and rising inventories, is a more dominant price driver than the temporary supply disruption from the refinery fire.
• Consider hedging long crude positions or preparing for further downside, as credible analyst targets suggest prices could test the $58.00 to $55.00 range for WTI if the anticipated supply increase materializes.
• Monitor the upcoming OPEC+ meeting for a definitive decision on production quotas and watch subsequent weekly EIA inventory data to confirm the emerging trend of a market surplus.
• For those holding Chevron (CVX), the fire at the El Segundo refinery presents a specific operational risk that could negatively impact the company's Q4 refining throughput and margins; further disclosures on the incident's severity should be watched closely.
