USO Surges 3.5% as Iran Declares Strait of Hormuz Closed Amid Escalating War

Geopolitical Shockwaves and the Hormuz Chokepoint

The primary catalyst for today's sharp move is the official declaration by Iran’s Islamic Revolutionary Guard Corps (IRGC) that the Strait of Hormuz—the world’s most vital oil transit artery—is effectively closed to ships aligned with the United States and its allies. This follows weeks of intensifying military exchanges between U.S.-Israeli forces and Iran. The Strait typically handles roughly 20% of the world's daily oil consumption, and its closure has triggered what the International Energy Agency (IEA) is calling the "largest supply disruption in the history of the global oil market."

Market participants are currently pricing in a massive supply deficit. While benchmark U.S. crude (WTI) has climbed toward the $100-per-barrel threshold, the USO ETF has outperformed, rising 3.49% in intraday trading on heavy volume of 3.2 million shares. The move reflects a "risk-off" flight to commodities as the "fog of war" settles over the Persian Gulf.

Broad Market Fallout and the Inflation Tax

The surge in energy prices is acting as a significant headwind for the broader equity market. While USO and energy-sector peers are rallying, the S&P 500 (SPY) is down 0.62%, and the tech-heavy Nasdaq is seeing even steeper declines. Analysts note that a sustained spike in oil prices effectively acts as a tax on global consumers and businesses, raising costs for everything from logistics to manufacturing.

Jim Bianco, president of Bianco Research, noted that recent diplomatic efforts have done little to soothe the nerves of traders. "Any further statements about a deal are white noise to the markets," Bianco stated, emphasizing that only a confirmed de-escalation from Iranian authorities would likely reverse the current trend. Similarly, Helima Croft of RBC Capital Markets warned that the market's impact from any potential OPEC output increase will be limited due to a lack of actual production capabilities outside of Saudi Arabia and the UAE.

USO Fund Performance and Internal Metrics

Adding to the fund's momentum, the United States Oil Fund, LP reported its monthly results for February 2026 today. The fund disclosed a net income of $46.8 million, driven by strong realized gains on commodity futures and swap contracts. This financial stability, combined with robust investor inflows into energy derivatives, has bolstered the fund's Net Asset Value (NAV) to approximately $1.15 billion. The technical setup for USO remains bullish, with the fund trading near its 52-week high of $125.19 as it breaks out of its short-term moving averages.

Forward-Looking Perspective

Investors are now focused on the April 6 deadline set by the U.S. administration for Iran to reopen the Strait or face further strikes on its energy infrastructure. While the IEA has authorized the release of 400 million barrels from emergency reserves to stabilize the market, analysts warn that supply-side measures may not be enough to offset a total closure of the Gulf. If the blockade persists, energy experts suggest WTI could test the $120 level, which would likely push USO well beyond its current multi-year highs. Investors should remain braced for extreme volatility as the April 5 OPEC+ meeting approaches.
