Shares of USO tumbled -3.09% to $128.12 on August 25, 2026, as traders unwound bets that U.S.-Iran tensions would choke global crude supply. The selloff caps a volatile week — USO swung from $130.66 last Monday to $134.64 on Thursday before reversing hard — and forces investors to ask whether the fund's recent rally was built on geopolitics rather than fundamentals. Oil Prices Sink as Sanctions Replace Bombs, but Can the Strait of Hormuz Calm Last?

USO slid 3.09% to $128.12 on August 25 as traders concluded that Washington's pivot from military strikes to economic warfare against Iran poses far less immediate danger to the world's oil supply. Oil prices fell to a one-week low on Tuesday as traders shrugged off the latest U.S. sanctions threat against Iran, viewing economic pressure as posing less risk to oil supplies than a military escalation. The reversal erased most of USO's gains from the prior week and raises a pointed question: how much geopolitical fear premium is still left to unwind?

Sanctions Sound Tough but the Market Isn't Scared

Oil prices fell Monday, even after the U.S. rolled out what has been described as its toughest-ever sanctions campaign against Iran.

The plan, dubbed "Operation Economic Outcast," includes no exemption for China; Treasury Secretary Scott Bessent called it an "economic D-Day." Yet WTI settled around $84.89 — down roughly 2.5% — because traders read economic isolation as a slower squeeze on barrels, not a sudden supply shock. For USO holders, the takeaway is clear: headline-grabbing rhetoric doesn't automatically support prices when the market sees diplomacy, not destruction.

Strait of Hormuz Flows Are Still Far Below Normal Even as risk premiums deflate, the physical picture remains tight. While a U.S.-Iran agreement boosted flows, volumes only reached about 40% of the roughly 15 million barrels that transited the Strait of Hormuz each day in 2025.

Reports indicated that around 16 million barrels crossed the waterway in a single night last week, although flows can vary significantly. Any renewed disruption — Iran has warned it retains the ability to respond — could snap prices right back up.

Analysts See a Wide and Volatile Trading Range Ahead

Commonwealth Bank of Australia expects Brent to trade between $70 and $100 a barrel in the second half of 2026, warning that even a modest recovery — just 50–60% of pre-war Hormuz flows — could revive expectations of an oversupplied market. That's a $30 band of uncertainty, meaning USO could swing violently in either direction based on a single headline from Tehran or Washington.

A Wild 2026 Explains Why the Premium Existed in the First Place

WTI's 52-week range stretches from an intraday low of $54.97 in December 2025 to a high of $119.47 in March 2026 — a span driven by the Iran war and Hormuz closure. As one analyst noted, "Iran still retains the ability to respond by disrupting shipping, which continues to keep a residual premium in the oil price." Today's selloff removes a layer of fear, not the underlying risk. Investors betting the calm will hold should remember: sanctions can be slow-burn, but the Strait can close overnight.
