USO Surges Over 7% in Pre-Market as Iran Conflict Escalates, Threatening Oil Supply
The United States Oil Fund (USO) is experiencing a significant pre-market surge, climbing over 7% in early trading today, Friday, March 6, 2026. This sharp upward movement is directly linked to escalating geopolitical tensions in the Middle East, particularly concerns surrounding the Strait of Hormuz and its impact on global crude oil supplies.
The United States Oil Fund (USO), an exchange-traded fund designed to track the daily price movements of light, sweet crude oil, is a sharp mover in pre-market trading, gaining +7.13% to an undisclosed price. This substantial rally comes as the broader S&P 500 (SPY) remains flat, highlighting a sector-specific reaction to heightened geopolitical risks.
Geopolitical Tensions Fuel Oil Price Spike
The primary catalyst for USO's ascent is the intensifying conflict in Iran, which has sent crude oil prices soaring. The death of Iranian Supreme Leader Ayatollah Ali Khamenei on February 28, 2026, has fundamentally altered the risk landscape across global energy markets. Prediction markets are now assigning an 85.2% probability that Iran will close the Strait of Hormuz before the end of 2026, a critical chokepoint through which approximately 20% of the world's oil trade flows.Reports indicate that tanker traffic in the Strait of Hormuz has already ground to a halt, creating significant supply concerns. This disruption was further exacerbated by a tanker explosion off Kuwait on March 5, 2026, which jolted oil markets and underscored the fragility of supply routes in the region.
As a direct consequence, the West Texas Intermediate (WTI) crude benchmark has topped $80 per barrel, surging 21% since the conflict began last Saturday. Brent crude also spiked to $77.24 per barrel on March 2. USO, which primarily invests in futures contracts for light, sweet crude oil, is directly benefiting from this upward pressure on crude prices. The fund's futures-roll structure is noted to perform more favorably in backwardation environments, which are typically created by acute supply shocks.
Market Context and Outlook
USO's strong performance in early trading today follows a period of notable gains. The ETF rose 5.19% on the most recent trading day, Thursday, March 5, 2026, marking its sixth consecutive day of gains. Over the past two weeks, USO has advanced by 18.62%. Trading volume for USO in pre-market has already reached 1.8 million, indicating strong investor interest ahead of the open.While the immediate focus is on the geopolitical premium being priced into oil, the situation remains fluid. The Trump administration is reportedly considering measures to address rising energy prices, including potential actions involving the oil futures market. However, for now, the escalating tensions in the Middle East continue to dominate sentiment, suggesting that oil prices and, by extension, USO, may remain elevated as long as supply risks persist.
