Crude Oil and OPEC+: Brent, WTI, Quotas Daily — 2026-09-15
Brent crude surged past $108 per barrel as geopolitical tensions in the Middle East and the Strait of Hormuz escalated, driving hedge funds to their most bullish positions since May. Simultaneously, U.S. refining margins hit record highs due to severe fuel supply squeezes, prompting Goldman Sachs to double its 2027 diesel margin forecasts. While OPEC+ held production quotas steady, the alliance faces mounting pressure to address 2027 quota disputes amid falling global inventories.
Crude Oil and OPEC+: Brent, WTI, Quotas Daily — 2026-09-15
Top developments
Brent Spikes to $108 Amid Hormuz Tensions
On September 14, Brent crude spiked to $108.49 per barrel at the Asian opening, marking a significant escalation from the $99–$100 range seen earlier in the week. This surge was driven by fading hopes for a quick U.S.-Iran resolution and renewed attacks in the region, which Standard Chartered warned has built a market prone to "sharper, more frequent spikes". The persistent risk premium supports higher settlements for both Brent and WTI, complicating inflation control efforts globally.
Record Refining Margins and Diesel Crisis
U.S. refiners are experiencing an unprecedented rally, with stocks for Valero, Marathon Petroleum, and Phillips 66 more than doubling as record fuel crack spreads boost margins. U.S. diesel prices hit a record $5.901 per gallon despite crude trading cheaper, highlighting a structural refining margin crisis driven by lost Middle Eastern and Russian supplies. Goldman Sachs has responded by more than doubling its 2027 diesel refining-margin forecasts to $63 a barrel, citing depleted fuel inventories and refinery outages that prevent near-term relief.
Hedge Funds Pile Into Fuels and Crude
Hedge funds have increased bullish bets on Brent crude to their highest levels since May, reacting to prolonged disruptions in energy flows through the Strait of Hormuz. Positioning has shifted aggressively into fuels as well, with analysts noting that the loss of Middle Eastern and Russian supplies is difficult to replace. This financial speculation amplifies physical supply tightness, keeping WTI near $99.50 and supporting continued upward pressure on energy costs.
EIA Lifts Brent Forecast Amid Falling Inventories
The U.S. Energy Information Administration (EIA) raised its Brent crude oil spot price forecast to average around $90/barrel for the remainder of 2026, citing significant inventory drawdowns. Global oil inventories fell by an average of 3.9 million b/d in the second quarter of 2026 and are projected to fall by another 3.0 million b/d in the third quarter. In the U.S., crude inventories decreased by 400,000 barrels in the week ending September 4, further tightening the domestic market and supporting WTI settlements.
Local view
Arabic-language media highlights the coordination between Riyadh and Moscow within OPEC+ as oil approaches the psychological $100 barrier. Asharq Al-Awsat reports that Saudi Arabia and Russia are aligning strategies to manage supply security concerns, even as OPEC+ officially maintains current production quotas without new changes. Meanwhile, Al Jazeera notes that Houthi attacks on Saudi infrastructure continue to exert upward pressure on prices, complicating the regional security landscape that underpins OPEC+ stability.
