Iran War Continues to Squeeze Global Commodity Supply Even as Fighting Ebbs

Seven months after war erupted, the Strait of Hormuz remains nearly closed, with helium, fertilizer, and oil deliveries severely disrupted. As negotiations stall, the toll extends far beyond energy prices.

The war between the United States, Israel, and Iran that began in late February 2026 has created what the International Energy Agency called the largest supply disruption in global oil market history. Iran closed the Strait of Hormuz, through which roughly 20% of global oil and LNG passes, in response to US and Israeli airstrikes that killed Supreme Leader Ali Khamenei. Though a ceasefire was signed in June and extended indefinitely in April, it collapsed on July 8 when Iran attacked commercial vessels to assert control over the strait. As of mid-September, the waterway remains effectively closed: maritime tracking data shows only 8–12 vessels transiting daily, against a pre-war baseline of 85 per day. Beyond oil prices, the crisis has strangled three critical supply chains stacked in sequence. In late February, Iranian drones struck Qatar's Ras Laffan facility, which produces about one-third of global helium as a byproduct of liquefied natural gas. That facility remains offline, disrupting the semiconductor chip and medical imaging industries just as major tech firms are scaling AI infrastructure buildout. The closure of the strait has also stranded roughly 33% of the world's specialized cryogenic containers used to transport liquefied helium, which evaporates in 45 days and cannot be held for long. Helium prices have surged 70–100% from pre-war levels, and the market is losing approximately 5.2 million cubic meters monthly with almost no spare capacity globally. Fertilizer supply is the second wave of disruption, working on a longer fuse. Gulf states supply about 45% of global sulphur and 50% of global urea exports, both critical for fertilizer production. Petrochemical feedstocks for plastics—70% of Asia's naphtha supply—also transit the Strait, prompting force majeure declarations and production cuts at crackers in Singapore, Indonesia, and South Korea. Market analysts estimate feedstock cost increases of 15–25%. The shortage will not show up in food prices immediately; it works on a six-to-nine month lag, feeding into harvests after the Q2 2026 planting season across South Asia and East Africa. Iran has also imposed what industry calls "transit contributions" of $2.50–3.00 per barrel equivalent on ships passing through the strait under a fragile arrangement. A naval blockade of Iran's own ports, reimposed in July, has halted Iranian oil exports and left Iran relying on diminishing floating stockpiles from before the blockade. Cumulative oil losses exceeded 1.3 billion barrels by June, prompting a global emergency reserve release more than double what was ordered after Russia's 2022 invasion of Ukraine. Oil prices have advanced more than 18% in September alone as the market braces for prolonged conflict.

How could this affect you

Traced by who's actually in the path of this — not everyone is.

Direct

Semiconductor and medical device manufacturers

Helium supply has dropped to near-zero due to damage to Qatar's sole major production facility and blockade of the Strait of Hormuz; spot prices have surged 70–100%; no substitute exists, and helium evaporates rapidly, making long-term storage impossible.

Likely

Global food producers and consumers in South Asia and East Africa

Sulphur and urea exports from the Gulf—45% and 50% of global supply respectively—are stranded; fertilizer shortages will lag six to nine months, affecting planting seasons and causing food price increases in late 2026 and 2027.

Direct

Plastic and petrochemical producers in Asia

70% of naphtha feedstock for polyethylene, polypropylene, and other polymers transits the Strait; production at major crackers in Singapore, Indonesia, and South Korea has been curtailed or halted, raising input costs 15–25%.

Direct

Gasoline and diesel consumers globally

Oil prices have advanced 18% in September; pump prices hit Labor Day records, and diesel is expected to cross $6 per gallon for the first time. The strait remains nearly closed despite US claims of escort operations.

Likely

Companies with operations in the Persian Gulf and Strait of Hormuz

Iran has imposed transit tolls of $2.50–3.00 per barrel equivalent; shippers bake these costs into differentials, raising effective LNG and helium container rates and increasing operating costs for any vessel movement through the waterway.

Analysis

The available reporting heavily emphasizes the US and Israeli framing of the war as a response to Iranian threat and regional aggression, with the Strait of Hormuz closure portrayed as Iranian coercion. Coverage of the financial and commodity toll is consistent across Western, Gulf, and Asian outlets, but the causality is rarely inverted: few sources foreground the US naval blockade of Iranian ports as an act of economic strangulation that prompted Iranian counter-pressure on the Strait. Iranian state media frames the Strait closure as assertion of national sovereignty over Persian Gulf waters in response to unwanted military occupation; this framing is nearly absent from Western reporting. Additionally, the timeline of the US blockade (imposed April 13, lifted May 29, reimposed July 8) gets less airtime than the Iranian Strait closure, making the sequence of escalation appear one-directional. Finally, reporting on secondary commodity effects (fertilizer, helium, plastics) treats them as unfortunate collateral damage rather than exploring whether either side is deliberately weaponizing these supply chains to inflict maximum global economic pain. This narrative gap matters: if fertilizer shortage is a predictable second-order consequence of Strait closure that Iran foresaw, coverage that treats it as accidental obscures the true scope of the conflict's strategic design.

Chanakya's Move

Whose move this was, what they're betting on, what could counter it.

Iran's strategy is to hold the Strait of Hormuz hostage as leverage in negotiations over nuclear programs, sanctions relief, and regional status. By threatening global energy and commodity flows without fully blocking them—maintaining just enough passage to avoid catastrophic global backlash—Iran raises the cost of continued military pressure on itself and forces the US and its allies to negotiate from a position of economic pain. The June Islamabad Memorandum codified this: Iran agreed to tone down Strait disruptions in exchange for sanctions relief, but then resumed attacks when diplomatic progress stalled, signaling willingness to escalate if US demands (nuclear caps, regional missile limits) remain non-negotiable. The US counter-move is the naval blockade of Iranian oil exports, impoverishing Iran to extract concessions. Both sides are betting they can absorb the secondary damage—global inflation, supply chain chaos, regional inflation—longer than the other side absorbs military attrition. The bet hinges on whether Trump's administration can tolerate $100+ oil into the 2024 midterms and beyond, and whether Iran's budget and morale can survive a prolonged chokehold on export revenue. Neither side has signaled willingness to move on the core disputes: Iran insists on zero enrichment caps as illegitimate; the US insists enrichment must be minimal or zero. The Strait remains a tool, not a resolution.
