The Iran conflict and the closure of the Strait of Hormuz have caused widespread global shortages of essential materials like naphtha, aluminum, helium, tungsten, nitrogen, and phosphate, disrupting industries from snack packaging and canned beverages to high-tech manufacturing and agriculture. These shortages threaten critical sectors including food production, medical technology, and military supplies, highlighting the vulnerability of global supply chains to geopolitical tensions.
The ongoing conflict involving Iran has triggered significant disruptions in global supply chains, affecting a wide range of consumer and industrial goods. One notable example is Calbee, Japan’s largest snack manufacturer, which announced it will switch its product packaging from colorful designs to black and white labels due to a shortage of naphtha. Naphtha, an essential ink ingredient derived from petroleum, is largely imported by Japan from the Middle East through the Strait of Hormuz, a critical shipping route that has been closed since the US and Israel attacked Iran in late February.
The closure of the Strait of Hormuz has caused ripple effects worldwide, including in India, where shortages of aluminum have led to a scarcity of canned beverages like Diet Coke. This scarcity has even given rise to “Diet Coke parties,” where the drink is treated as a rare commodity and sold at inflated prices. Additionally, India faces shortages of cooking gas, forcing some restaurants to consider closing, while the ceramics industry has been hit hard as natural gas shortages disrupt kiln operations.
Qatar, responsible for about one-third of the global helium supply, ceased helium production in March after Iranian strikes damaged two liquefied natural gas facilities. This helium shortage poses a serious threat to the operation of MRI machines and the manufacturing of advanced technologies such as artificial intelligence chips, smartphones, and electric vehicles. Helium’s critical role in these industries underscores the far-reaching impact of the conflict on high-tech manufacturing.
Another key material affected is tungsten, prized for its heat resistance and electrical conductivity, making it vital for AI chip production and armor-piercing munitions. The ongoing war has accelerated the use of tungsten in military applications by the US and Israel, rapidly depleting American tungsten reserves. This dual demand from both industrial and military sectors exacerbates the scarcity of this crucial metal.
Furthermore, the blockade of the Strait of Hormuz has disrupted roughly one-third of global shipments of nitrogen and phosphate, essential components of fertilizers. This disruption threatens to severely impact global fertilizer supplies, potentially driving food prices to unprecedented highs in the coming year. The widespread shortages caused by the Iran conflict highlight the interconnectedness of global supply chains and the vulnerability of critical resources to geopolitical tensions.
