Iran Intensifies Attacks on Ships in the Strait of Hormuz

Iran has stepped up strikes on commercial shipping in the Strait of Hormuz this week, hitting three vessels in roughly 24 hours and reigniting the oil supply risk premium that traders had started to fade. Iran’s military fired at least two missiles at commercial ships transiting the Strait of Hormuz on Monday night, and the IRGC attacked a third commercial ship on Tuesday morning, U.S. officials said.

What happened

The UKMTO reported early on Tuesday that a tanker had been struck by a projectile on its port side while moving southbound about 8 nautical miles off the coast of Limah in Oman, causing a fire. Reuters sources identified the ship as a Qatari LNG tanker called Al Rekayyat, with the crew reported safe.

A second vessel, a Saudi-flagged crude oil tanker, was also damaged in the strait after the IRGC fired missiles, sources told Reuters. Saudi Arabia condemned the strike on its vessel, the Wedyan, calling the attacks an assault on the security of international navigation and on global energy supplies.

Why it matters for markets

Brent crude rose about 2.5% on Tuesday to trade near $73.83 a barrel, with WTI up a similar amount to around $70. Higher oil prices pushed U.S. Treasury yields up, with the 10-year rising to 4.51% from 4.48%, as investors worried that renewed inflation could force the Fed and other central banks to hike rates.

The Joint Maritime Information Center raised the Hormuz threat level to severe, warning mariners that deliberate hostile action by Iran is likely under current conditions.

The route problem

Iran’s military has warned it will target ships that do not use a northern route approved by Tehran, and vessels are avoiding the traditional route through the middle of Hormuz that Iran mined. Iran had agreed to safe passage under the terms of an interim deal signed with the U.S. on June 17, but Tehran has since launched a series of attacks on ships using the route protected by the U.S. Navy.

U.S. response

U.S. Central Command said it launched a series of strikes on Iran in response to the attacks, targeting air defenses, radar sites, anti-ship missile sites, and dozens of small boats used by Iran’s Revolutionary Guard. The Treasury Department also revoked a waiver that had allowed Iran to sell oil and petrochemicals, cutting off a significant revenue source negotiated during recent talks.
