Oil prices are experiencing a dramatic reversal, tumbling to five-month lows as a peace deal between the US and Iran has unleashed a wave of supply, overwhelming global demand. Brent crude, the international benchmark, fell below $72 a barrel, while West Texas Intermediate (WTI) traded even lower at around $68 a barrel by July 6, 2026. This starkly contrasts with less than three months ago when the physical oil benchmark hit an all-time high and industry executives warned of critically low inventories. The downturn has erased all wartime gains, with Brent crude futures plummeting 43% from their late April peak.

The primary driver of this glut is the release of over 60 million barrels of trapped oil that were frozen when the war began, facilitated by the reopening of the Strait of Hormuz. Additionally, OPEC+ nations, including Saudi Arabia and Russia, have agreed to a modest increase of 188,000 barrels per day in August, further contributing to the supply surge. Saudi Arabia and the UAE have also ramped up exports close to pre-war levels, and Iranian oil, previously subject to sanctions, is now available for purchase, adding to the mounting supply.

Adding to the oversupply concerns is unexpectedly weak demand from China. Chinese refiners, who typically are major buyers, have conspicuously reduced their imports by approximately five million barrels a day compared to pre-war levels and have yet to return meaningfully to the market. This has led to historical lows for grades of oil typically bought by China, such as Oman crude, which is trading at a $4 discount to the Dubai benchmark. Analysts from Morgan Stanley to Goldman Sachs warn of a potential glut extending into 2027, with Citigroup flagging the possibility of Brent crude returning to $60 by year-end. The market is now in a contango pattern, incentivizing traders to store barrels as supply outstrips demand.
