The U.S. military launched its first strikes against three Iranian oil tankers—escalating the Strait of Hormuz conflict from 'attacking facilities' to 'disrupting transportation'.

This week, the U.S.-Iran military conflict underwent a qualitative shift: for the first time, U.S. strikes targeted oil tankers actively engaged in crude oil transportation—not just coastal military installations and infrastructure. As a result, the risk of supply disruption in the Strait of Hormuz has moved from theoretical expectation toward tangible reality, forcing a fundamental reassessment of global crude oil pricing logic. According to CCTV International News, U.S. Central Command (CENTCOM) issued a statement on September 5 stating: "Following ballistic missile launches by Iran’s Islamic Revolutionary Guard Corps (IRGC) against two U.S. naval vessels patrolling regional waters, CENTCOM forces struck three Iranian crude oil transport vessels." CENTCOM subsequently released a strongly worded statement: "We will not hesitate to defend U.S. forces—and, if necessary, will destroy Iran’s limited and exposed oil tanker fleet." This marks the first time since the current round of conflict erupted in February that the U.S. military has designated actively sailing crude oil transport vessels as strike targets—signaling a formal escalation from "targeting production capacity and facilities" to "targeting transportation corridors." Market focus has accordingly shifted from "how much will Iran’s output decline?" to "can vessels safely transit the Strait?", placing upward pressure on both oil price and marine insurance pricing frameworks. Earlier the same day, Iranian media reported that an oil tanker near Kharg Island was reportedly hit by a U.S. missile; evacuation efforts were underway, with no casualties reported so far. The previous day, Tehran allegedly fired anti-ship missiles at vessels in the Strait of Hormuz. Such concentrated actions targeting maritime traffic lines have continuously elevated regional shipping risk premiums, subjecting the Strait of Hormuz to its most severe security test since the outbreak of the conflict. A qualitative shift in targeting: from destroying facilities to striking oil tankers Over the past week, U.S. strikes have focused on IRGC air defense positions, mine-laying facilities, radar systems, maritime assets, communications sites, and ground infrastructure at key oil export hubs—including Larak Island and Kharg Island. Last Sunday, CENTCOM conducted a "limited and precise operation" against Iranian mine-laying units inside the Strait; on Tuesday, it launched another round of strikes against IRGC air defense positions and mine-laying facilities. This direct strike against three actively sailing crude oil tankers expands the target set from static military assets to dynamic transport vehicles. The U.S. side stated the trigger was Iran’s ballistic missile launch against two U.S. Navy warships. CENTCOM’s public warning—"we will destroy Iran’s oil tanker fleet if necessary"—further signals Washington’s intent to treat Iran’s energy export capability itself as a legitimate target.

U.S.-Iran tensions are 'on the verge of eruption'; this weekend, nerves are frayed across the region! Oil prices hit $117 for the first time since April, surging over 10% in one month.

At the level of communications infrastructure, media reports on October 23 revealed that two senior Iranian security officials disclosed that, should the United States and Israel launch further attacks against Iran, the Iranian government has drawn up a detailed plan to strike undersea communication cables in the Gulf region. Yadollah Javani, political deputy to the commander-in-chief of Iran’s Islamic Revolutionary Guard Corps (IRGC), had previously identified seven major fiber-optic cables running beneath the Strait of Hormuz as potential "new targets." One official further warned that Iran may attempt to obstruct repair efforts following cable damage—thereby prolonging communication outages—and emphasized that retaliatory targets would no longer be constrained by previously declared "red lines." The significance of this threat lies in the fact that the potential impact of any ensuing conflict may extend beyond oil production and maritime transport. According to data from the International Telecommunication Union (ITU), undersea cables carry approximately 99% of global internet traffic. However, Alan Mauldin, Research Director at telecom research firm TeleGeography, noted that international bandwidth routed through the Strait of Hormuz accounts for less than 1% of the global total—meaning that even if related cables were damaged, the overall global internet impact would likely remain limited. Nevertheless, Gulf-region countries and enterprises reliant on those specific cables would face more immediate and severe communication disruptions. Shipping crisis intensifies in the Strait of Hormuz; tanker mine incidents shake markets Shipping safety risks in the Strait of Hormuz surged sharply this week—becoming one of the direct catalysts behind the oil price spike. As reported by Wall Street Insights, citing CCTV News, on October 23 local time, the IRGC Navy announced that two supertankers attempting to illegally traverse the southern Strait of Hormuz had struck mines earlier that day; explosions and fires disabled both vessels’ engine rooms, prompting crews to abandon ship. Together, the two tankers carried over 4.5 million barrels of crude oil. It should be noted that this account remains solely Iran’s unilateral statement; vessel names, exact damage assessments, and whether crude oil leaked remain unconfirmed by independent sources. Media reports also indicated that the IRGC Navy had previously announced on Wednesday that its forces tracked and simultaneously struck four vessels suspected of involvement in illegal oil transfers in northern Persian Gulf waters—setting them ablaze—and that three other vessels collided with mines west of the Strait of Hormuz. Iran’s state television reported on Thursday that a total of seven tankers had been attacked or struck mines during the week. Ole Hansen, Head of Commodity Strategy at Saxo Bank, told the Financial Times: "Markets are growing increasingly concerned that further attacks could damage production, processing, or export infrastructure—causing disruptions that cannot be easily mitigated simply by rerouting shipments." Nonetheless, preliminary data from ship-tracking firm Kpler—cited by the Financial Times—showed that Gulf oil exporters (excluding Iran) posted weekly export volumes above pre-war averages last week. Yet data from other tracking firms indicate flows still remain below that threshold. Some Gulf producers are accelerating exports ahead of further deterioration in the situation—but their ability to increase shipment volumes remains constrained by limited tanker availability. Inflation and markets: the energy shockwave is already spreading The ripple effects of surging oil prices have begun transmitting across broader financial markets. Brent crude futures for April 2027 continued trading above $100 per barrel on Friday—indicating traders expect high oil prices to persist far longer than previously anticipated.
