The conflict between Iran, the United States and Israel has escalated into a big international disaster, with penalties which might be achieving a ways past the Center East. The closure of the Strait of Hormuz, during which round 25% of the arena’s oil ordinarily passes, has rattled international power markets.
This has most effective been worsened by way of the United States naval blockade of Iranian ports, which used to be imposed on April 13 in an try to limit Iran’s skill to export its oil. In early Might, the United States Protection Division estimated that Iran were denied just about US$5 billion (£3.7 billion) in oil earnings because of the blockade.
However Iran’s position within the international economic system isn’t simply centred on oil, because the warfare has proven. From methanol to pistachios and cement, the conflict is choking industry in a spread of Iranian exports that underpin provide chains throughout Asia and the Center East.
Methanol
Methanol is likely one of the conflict’s maximum consequential commodity tales. It’s utilized in numerous commercial and family merchandise, together with windshield cleansing fluids, antifreeze, plywood, plastic and gas. Iran produces more or less 10 million tonnes of methanol a 12 months, made from its huge herbal fuel reserves, making it the arena’s second-largest provider after China.
However since hostilities started in February, Iranian methanol exports have successfully ceased. Moves on Iran’s fuel infrastructure have bring to an end each the feedstock and effort had to run the rustic’s methanol crops. Mixed with the closure of Hormuz and suspension of operations at Qatar’s Ras Laffan and Mesaieed herbal fuel complexes, over 30% of worldwide seaborne methanol provide has been got rid of from the marketplace.

China is being suffering from the disruption maximum seriously. It imported round 14 million tonnes of methanol in 2025, with a lot of it coming into the rustic thru coastal ports. For China, uploading methanol has traditionally been more economical than hauling home manufacturing overland from its far flung western areas to call for centres within the east.
Home manufacturers have lifted output to offset a part of the shortfall. However this selection provide comes at a considerable value for jap commercial customers, who at the moment are paying as much as 500 yuan (£55) according to tonne extra for methanol produced regionally than methanol sourced from out of the country.
Pistachios
Iran is the second-largest manufacturer of pistachio nuts globally, sandwiched between the United States in first and Turkey in 3rd. Pistachio costs reached US$4.57 (£6.10) a pound in March, their perfect stage since 2018.
Iran’s pistachio orchards are concentrated within the north-eastern province of Khorasan, the place US and Israeli moves had been much less intense than within the west and south. However key ports close to the Strait of Hormuz had been seriously disrupted, with studies suggesting that Iranian pistachio exports have fallen by way of round 30% at the 12 months.
The conflict has added power to a marketplace that used to be already below pressure. Harvests a number of the 3 main manufacturers fell wanting expectancies in 2025 because of drought. Iranian exports have been additional constrained from January 2026, when the federal government in Tehran replied to inner unrest by way of shutting down the web. This restricted touch between exporters and overseas patrons.
The clearest beneficiary of constrained Iranian provide is the United States. A 40-year-old US tariff on Iranian in-shell pistachios, presented after the 1979 revolution, steadily helped California’s home trade turn out to be an international chief. The majority of the pistachios fed on in the United States at the moment are grown there.
The have an effect on is as a substitute falling on south Asian outlets in puts like Kashmir and at the Gulf-driven “Dubai chocolate” growth, which is based closely on Iranian kernels for the pistachio cream filling. Within the six months to March 2025 on my own, Iranian pistachio exports to the United Arab Emirates (UAE) rose by way of 40% when put next with the former 12 months as confectioners scrambled to satisfy emerging client call for for Dubai chocolate.
Cement
Iran additionally ranks as probably the most international’s greatest cement manufacturers. Its annual output of 70 million tonnes is in large part exported to neighbouring international locations. Iraq has traditionally been the principle purchaser of Iranian cement. Subsequent in line are Kuwait, Afghanistan and Syria.
Iranian cement output used to be already constrained earlier than the warfare by way of home fuel shortages and electrical energy rationing. Exports of clinker, the principle constituent of cement, have been down 17% in 2024 when put next with the former 12 months. All the way through the 2024 summer season energy disaster, 70% of cement kilns additionally halted operations.
Dependable wartime figures don’t seem to be but to be had, however the moves on Iran’s fuel infrastructure have worsened the feedstock downside. Brief suspensions of port operations, as took place within the southern Iraqi town of Basra in March following assaults on two tankers off the coast, have additional hampered Iran’s skill to export cement.

In the meantime, Iraq and Kuwait face a double bind. As Iranian cement provides tighten, each international locations are dropping the manner to compensate. Iraq ships 97% of its power exports throughout the Strait of Hormuz and Kuwait 100%. Each have close down manufacturing.
The cave in in state earnings is straining infrastructure budgets in those international locations. So even the place selection provide exists – from Turkey, Pakistan, Saudi Arabia and the UAE – Iraq and Kuwait lack the fiscal capability to take in the upper prices.
For years, a lot research of Iran has targeted at the nation’s isolation. However, in fact, Iran is concerned about provide chains in all places the arena – from meals to chemical substances and development fabrics. The conflict has made this abundantly transparent.
