Mashhad Strikes Push US-Israeli Campaign Into Iran’s Strategic Interior as Oil Hits $109
Month-long conflict sees deepest territorial penetration yet while Strait of Hormuz closure drives crude to highest levels since 2022.
US and Israeli forces struck aviation infrastructure at Mashhad Airport in early March, marking one of the deepest military operations into Iranian territory as a month-long campaign escalates beyond previous operational boundaries. The strikes targeted refueling aircraft at Mashhad Shahid Hasheminejad International Airport, with the Israel Defense Forces describing the operation as “possibly the most distant in its history.” Brent crude surged to $109.16 per barrel on April 2 as markets priced in sustained disruption across the Strait of Hormuz, where shipping has effectively halted under the threat of Iranian retaliation.
The conflict, which began February 28 with strikes that killed Supreme Leader Ali Khamenei, has now extended into its fifth week with no clear exit path. Mashhad’s location in northeastern Iran—far from the Persian Gulf theatre that defined the brief 12-day war in June 2025—signals a shift toward targeting strategic interior infrastructure rather than coastal military assets. The airport strikes hit both military refueling capacity and a Mahan Air civilian aircraft scheduled for a humanitarian medical mission to New Delhi, drawing Iranian accusations of war crimes.
Hormuz Chokepoint Drives Price Surge
The Strait of Hormuz, which normally handles roughly 20% of global oil and liquefied natural gas flows, has seen traffic collapse from a pre-war average of 77 vessel crossings per day to just four by March 3, according to Windward Maritime AI. Shipping insurance costs have spiked to approximately 5% of vessel value—five times the rates seen in the earliest days of the conflict and multiples above pre-war fractions of a percentage point. Close to 500 million barrels of total liquids have been lost to disruption as of late March, per CNBC analysis of flow data.
“This is currently an unmanageable risk. Insurance rates will fall—and the willingness of commercial operators to insure and send cargoes through the Strait will rise—only after Iran’s military capabilities are degraded.”
Bob McNally, President of Rapidan Energy Group
Brent crude soared approximately 55% in March alone, a record monthly surge for the contract dating back to 1988. The rally reflects not just supply loss but fundamental repricing of Middle Eastern export risk. “The potential effect on Oil Markets is hard to overstate,” Barclays analyst Amarpreet Singh told CNBC in early March, before the full scale of the Hormuz shutdown became apparent. Insurance underwriters have effectively priced commercial shipping through the strait as unviable absent crew safety guarantees that Iran shows no sign of providing.
Iranian officials designated Mojtaba Khamenei as new supreme leader on March 8 following the death of his father Ali Khamenei in the initial February 28 strikes. The succession, occurring amid active conflict, has complicated Western assessments of Iranian negotiating posture. Mojtaba’s willingness to authorize selective Strait access to aligned nations—China, Russia, India, Iraq, Pakistan, Thailand, and Malaysia—while blockading Western shipping suggests a more transactional approach to energy leverage than his predecessor’s ideological framing.
Escalation Beyond Previous Boundaries
The targeting matrix has expanded well beyond the 12-day precedent set in June 2025. US and Israeli forces have struck facilities across 16 Iranian cities, including nuclear infrastructure at Natanz, Islamic Revolutionary Guard Corps command nodes, and internal security apparatus sites used for domestic repression, according to analysis by the Foundation for Defense of Democracies. Iran has responded with over 500 ballistic and naval missiles and nearly 2,000 drones since February 28, according to Fars News Agency figures.
Casualty figures reported by Al Jazeera show at least 1,937 killed in Iran as of early March, with additional deaths across the region including 24 in Israel, 13 US soldiers, and 27 in Gulf states. The expansion of targeting to include civilian aviation infrastructure at Mashhad—where a scheduled medical aid flight was destroyed—marks a tactical shift that Iranian Foreign Minister Abbas Araghchi framed as justification for continued retaliation. “We will emphasize the continuation of Iran’s defensive operations against aggressors, including their military bases and facilities that are stationed in the territory of countries in the region,” Araghchi told Iran International.
Insurance Markets Price Indefinite Disruption
The mechanics of the Strait closure reveal why markets expect extended supply loss. War risk premiums have reached levels that make commercial transit economically unviable even before factoring in crew safety concerns. “Ships do not move without crews, and crews will not move unless they can be guaranteed to be safe,” V.Group CEO René Kofod-Olsen told the Insurance Journal. The US government announced a $20 billion reinsurance facility through the Development Finance Corporation to stabilise markets, but uptake remains minimal as underwriters view Iranian military capacity as largely intact despite sustained strikes.
- Brent crude trading $105-109 range represents new baseline until Hormuz threat resolves
- Insurance costs at 5% of hull value eliminate profit margin for most Gulf-origin cargoes
- Iran’s selective access policy fragments global oil market into aligned/non-aligned blocs
- Defense stocks repricing on extended conflict timeline; tanker rates surge on routing shifts
Iran’s announcement on April 1 that it would begin attacking 18 named US companies—including Google, Microsoft, Apple, Intel, IBM, Tesla, and Boeing—starting April 2 signals an expansion of the conflict into hybrid economic warfare. The threat, reported by CNBC, follows the entry of Houthi forces into the war on March 28, further complicating regional containment efforts. Trump administration officials have floated a potential 2-3 week exit window, but degradation of Iranian military capacity remains contested among intelligence assessments.
The Mashhad strikes demonstrate operational reach extending hundreds of kilometres beyond previous engagement zones, while the effective closure of Hormuz—now entering its second month—has produced the steepest monthly oil price surge in nearly four decades. With Iran maintaining sufficient military capacity to enforce selective Strait access and Western insurance markets pricing the risk as unmanageable, crude markets have settled into a new equilibrium where $105-109 Brent reflects not speculation but the structural reality of 17.8 million barrels per day of disrupted flows. The strategic interior targeting visible in Mashhad operations suggests this equilibrium may persist well beyond initial conflict timelines.
