Oil Prices Surge Past US$100/b Amid Middle East Attacks

Global crude oil prices surged past US$100/b following security strikes on Saudi Arabian infrastructure, Middle Eastern shipping disruptions, and sustained drone attacks on Russian refineries. These physical supply losses have severely impacted global distillate markets, pushing US retail diesel prices to an all-time high of US$6.06/gal. The compounding geopolitical constraints affect international energy traders, commercial logistics providers, and industrial power consumers as commercial OECD stocks remain 47.9 million barrels below five-year averages.

Global oil prices increased over 4% to reach a 16-week high on Monday following infrastructure strikes in Saudi Arabia and maritime disruptions in the Middle East. Both Brent and  US West Texas Intermediate (WTI) rose to over US$100/b, marking their highest levels over the past four months.

Brent futures rose US$4.68, or 4.5%, to US$109.29 per barrel, while US West Texas Intermediate (WTI) crude increased US$4.21, or 4.2%, to US$104.26 per barrel. Both benchmarks reached their highest levels since May 2026.

The price movement followed security developments across key maritime and supply routes. Yemen's Houthi movement reported launching missile and drone strikes against a Saudi military airbase in Khamis Mushait. A previous attack attributed to regional armed groups disabled Saudi Arabia's East-West pipeline, an infrastructure link that allows crude shipments to bypass the Strait of Hormuz by routing oil to the Red Sea. The pipeline's disruption puts up to 4% of global oil supply at risk, requiring the Red Sea port of Yanbu to rely on local inventories estimated to cover five to seven days of exports, according to Reuters.

Maritime transit data indicated that commodity vessel movements through the Strait of Hormuz dropped to single digits per day over the weekend, down from a recent 10-day average of 14. In parallel, Houthi forces advanced to Perim Island near the Bab el-Mandeb strait, while Iranian authorities issued a compliance list targeting 77 vessels operating in the region. Diplomatically, Gulf Arab nations canceled a scheduled meeting with Iranian representatives. 

Geopolitical Pressures Expand Refined Product and Diesel Shortages

In tandem with Middle Eastern supply disruptions, global refined product markets experienced significant upward pressure, driven by compounding constraints on refining capacity. US diesel futures traded near US$5.18/gal on Monday, while the US national average retail diesel price reached an all-time high of US$6.06/gal. 

The price surge in transportation fuels follows sustained Ukrainian drone strikes against Russian oil refineries, which reduced domestic fuel production and triggered export restrictions from Russia. US President Donald Trump publicly requested that Ukrainian President Volodymyr Zelenskyy halt attacks on Russian diesel infrastructure, citing the resulting global fuel shortages and economic impact, reported Al Jazeera. 

Ukrainian officials maintain that Russian energy assets are legitimate military targets that fund and fuel military operations. According to the International Energy Agency (IEA), the combination of military conflict in the Middle East and reduced Russian refinery output has tightened global middle-distillate supplies, compounding global energy market volatility. 

Tight Inventories and OPEC Production Cuts Deepen Market Vulnerability

The sudden price spikes occur against a backdrop of tightening global commercial stocks and localized production cuts across key producing nations. According to OPEC’s latest Monthly Oil Market Report, total OPEC crude production averaged 24.08MMb/d, but regional disruptions triggered sharp localized declines, including a 399Mb/d fall in Iranian output to 2.08MMb/d and a 75Mb/d drop in Saudi Arabian production to 7.28MMb/d.

This physical tightness has driven forward curves deeper into backwardation, supported by hedge funds and money managers expanding their net long positions in Brent and WTI futures by 12%. Although OECD commercial oil stocks increased by 9.8MMb to 2.7 billion b, inventories remain 47.9MM barrels below their five-year average, providing 59.3 days of forward cover. While OPEC lowered its 2026 global demand growth forecast to 400Mb/d due to industrial weakness across OECD nations, it expects a demand expansion of 2.4MMb/d in 2027, led by non-OECD markets in Latin America, Africa, and Asia.
