Strait of Hormuz Shipping Drops Amid U.S.-Iran Tensions

Ship traffic through the Strait of Hormuz has plunged to near three-month lows, undermining U.S. claims of dominance over the waterway even as Iran refuses to reopen it without sweeping concessions.

For energy investors and commodity traders, the gap between official rhetoric and on-the-ground shipping data represents a material risk premium that shows no sign of unwinding soon.

Key Takeaways

Hormuz vessel transits down ~90% from pre-war levels of 130 ships daily.
Iran refuses reopening without sanctions relief, troop withdrawal, and reparations.
Peace talks remain stalled; Houthis open new front at Bab al-Mandab.

Market reaction & context

According to trade intelligence firm Kpler, the five-day average of vessel transits through the Strait of Hormuz stood at roughly 13 as of Tuesday – near the lowest level recorded since May 12, and down sharply from the pre-conflict average of 130 ships per day ¹. Reuters separately reported that just eight ships crossed the strait on Tuesday, compared with a pre-war rate of 130 to 140 vessels daily ².

That near-total collapse in traffic – encompassing oil tankers, cargo vessels, and bulk carriers alike – represents a sustained supply-chain shock that has kept a geopolitical risk premium embedded in crude prices. Brent crude has remained elevated relative to pre-conflict baselines even as episodic ceasefire speculation briefly eased pressure on prices.

Competing narratives cloud the picture

President Donald Trump said on Truth Social that “The U.S.A. has total control over the Strait of Hormuz. I THINK WE WILL KEEP IT!” – repeating a claim he had made to reporters a day earlier ². Iran’s Persian Gulf Strait Authority directly contradicted that, saying in a post on X: “Claims and repeated posts by U.S. officials that the Strait of Hormuz is no longer blocked do not change the reality: the Strait of Hormuz remains blocked and will not be reopened until Iran’s conditions are accepted.” ¹

The duelling assertions have drawn scrutiny from independent analysts. Dennis Citrinowicz, a senior researcher at the Institute for National Security Studies, wrote on X: “The United States does not control the Strait of Hormuz. Despite everything that has happened, Iran retains sufficient capabilities to disrupt maritime traffic through the strait.” ²

Detailed analysis

Iran’s Supreme National Security Council laid out its terms over the weekend: an end to the U.S. naval blockade, full sanctions relief, American troop withdrawals from the region, and war reparations ¹. Washington has countered with its own reparations demands, leaving both sides in an impasse that has effectively frozen formal negotiations ¹.

The U.S.-Israel military campaign against Iran began on February 28. A Memorandum of Understanding signed in June briefly raised hopes for a settlement, but the agreement collapsed in mid-July as both sides resumed strikes ². Iran is currently pursuing parallel talks with Oman on the future management of the strait – discussions that explicitly exclude Washington ².

The conflict has also expanded geographically. Yemen-based Houthis struck an Egyptian-owned vessel in the Bab al-Mandab Strait on Tuesday, killing six people – the first fatalities from such an attack – opening a second chokepoint risk for global shipping ². Earlier disruptions to Hormuz shipments had already forced some carriers to reroute around the Cape of Good Hope, adding significant cost and transit time.

A U.S. Navy helicopter struck a Panama-flagged cargo vessel on Tuesday after it was deemed to be violating Iran’s blockade enforcement, illustrating how even vessels attempting transit face direct kinetic risk ². U.S. Energy Secretary Chris Wright said the seven-day average for oil leaving the strait had risen to “almost 9 million barrels per day,” a figure that analyst Brett Erickson of Obsidian Risk Advisors flatly rejected, writing on X that there is “zero evidence that 9Mbpd is exiting the Strait of Hormuz per day.” ²

Outlook / management quote

Mohammad Reza Naqdi, a senior advisor to the commander of Iran’s Islamic Revolutionary Guard Corps, told PBS on Tuesday that Tehran’s strategy is deliberate attrition. “We saw confusion and bewilderment in America. It became a war without a strategy. Every two or three days, they announced a new objective… Everything they tried, we can show how we were victorious,” Naqdi said ¹.

When asked whether Iran intended to drag the conflict out until Trump leaves office, Naqdi said the goal was to “attain deterrence,” describing prolonged conflict as one mechanism for imposing a cost on any future adversary ¹. Pakistan’s Foreign Ministry said Islamabad was working to “bring the two parties to the negotiating table,” with its deputy prime minister having held talks with officials from Iran, Saudi Arabia, and Kuwait on August 10 ².

Conclusion

With transit volumes near multi-month lows, peace talks stalled across multiple tracks, and a new front opening at Bab al-Mandab, the market conditions underpinning elevated energy-sector risk appear unlikely to resolve quickly. Prior episodes of U.S.-Iran tension de-escalation have triggered sharp crude sell-offs, suggesting that any credible breakthrough could rapidly reverse the risk premium – but the current negotiating dynamic offers little near-term catalyst for that outcome.
