Oil prices extended gains on Monday, pushing crude benchmarks to levels not seen in more than a month as fighting between the United States and Iran continued to squeeze tanker traffic through the Strait of Hormuz. The United States Oil Fund (AMEX:USO), a widely watched proxy for crude, traded at 128.85 dollars, up 2.66% on the day, with its relative strength index at 63.4, a reading that shows the rally still has room before it looks technically stretched.

Key Takeaways
- USO shares changed hands at 128.85 dollars, up 2.66%, within a 52 week range of 102.42 to 154.08.
- Strait of Hormuz transit volumes dropped to four vessels on Sunday from eight the prior day, according to shipping data.
- The U.S. carried out a ninth consecutive night of strikes on Iran, with Kuwait and Bahrain also reporting Iranian attacks.
- Roughly 20% of global oil supply normally moves through the strait, making the chokepoint central to the price move.
- Gulf exporters had actually raised crude and condensate shipments to their highest level since before the conflict began, before the latest escalation slowed flows.
Why Oil Prices Extend Gains as Hormuz Traffic Thins
The immediate driver is logistics, not just headlines. LSEG data cited by market analysts showed only four vessels transiting the Strait of Hormuz on Sunday, half the prior day's count. At least three oil products tankers and one very large crude carrier had entered the strait since Friday to load cargo, but the broader trend points to a stalled recovery in shipping through the passage. UBS analyst Giovanni Staunovo described the market as tightening again, a view echoed by ANZ analysts who called the supply narrative more bearish given the drop in transit volumes to single digits.
Escalation on the Water
Iran's Revolutionary Guard Corps said two tankers were disabled by explosions while attempting what it called an unsafe southern route through the strait, claiming U.S. forces had steered them there. That account has not been independently verified. Separately, a vessel was reported on fire northwest of Oman's Kumzar. Both sides have targeted shipping directly: Washington says it is enforcing a naval blockade on Iranian ports, while Tehran says it is policing vessels that violate its navigation rules.

Reading the Broader Market Signal
Crude's move sits alongside other cross asset signals worth weighing. A sustained supply shock through a chokepoint carrying a fifth of global oil flows tends to pressure the dollar's purchasing power narrative and can complicate the outlook for equity benchmarks tracked by SPY, QQQ and DIA, given energy cost pass through to input prices. Gold (GLD) and silver (SLV) often catch a geopolitical bid in tandem with oil during Middle East flare ups, while Treasuries (TLT) can see mixed flows as investors weigh inflation risk against safe haven demand. Real estate proxies like VNQ are more insulated short term but remain sensitive if energy costs feed into broader inflation expectations.
Where Hormuz Tensions Leave the Supply Outlook
Before the conflict, Gulf producers had actually lifted exports to their highest level since before the war began in late February, a reminder that supply capacity itself is not the constraint, transit safety is. Iran has also reportedly pressed the Houthis to shut the Red Sea route if U.S. strikes hit Iranian power infrastructure, which would widen the disruption beyond a single chokepoint. Whether transit volumes stabilize or keep falling will likely determine if USO's rally, already up sharply from its 52 week low near 102.42, has further room to run toward its 154.08 high.
Frequently Asked Questions
Why is oil increasing?
Oil is rising because fighting between the United States and Iran has cut the number of tankers safely transiting the Strait of Hormuz, a route that normally carries about 20% of global oil supply.
Why oil price increased?
Prices increased after transit volumes through the strait fell to single digits and both the U.S. and Iran began directly targeting shipping traffic, raising fears of a prolonged supply disruption.
Will oil prices drop further?
Prices could ease if a ceasefire holds and tanker traffic through the strait normalizes, since Gulf producers have shown they can raise exports quickly when shipping lanes are safe.
Will oil prices continue to rise?
Further gains are plausible if strikes on vessels persist or spread to the Red Sea, since each drop in verified safe transit volume has tightened the market further.
Will oil prices continue to go up?
Momentum indicators like USO's RSI of 63.4 suggest the uptrend has room before turning overbought, but the trajectory depends heavily on how the Hormuz conflict develops in coming days.
