Iran Conflict Fallout Spikes Manufacturing Costs

The de facto closure of the Strait of Hormuz is creating a dual-chokepoint crisis, as Houthi attacks have already disrupted the Suez/Bab el-Mandeb corridor. With roughly one-third of global seaborne crude trade now compromised, the situation surpasses the severity of the energy supply disruption seen after Russia's invasion of Ukraine. This forces vessels onto longer and more expensive routes around Africa, increasing transit times by up to two weeks and fuel consumption by as much as 40%. The Strait of Hormuz is the world's single most critical energy chokepoint, handling about 20% of global oil consumption and 20% of liquefied natural gas (LNG) trade. At its narrowest, the waterway is only 21 nautical miles wide. Major Asian economies are most exposed, with roughly 84% of the 20 million barrels per day of crude oil transiting the strait destined for markets like China, India, Japan, and South Korea. While some alternative pipelines exist, they offer limited relief. The combined spare capacity of pipelines in Saudi Arabia and the UAE that bypass the strait is estimated at only 2.6 million barrels per day. This is a fraction of the volume that normally passes through the waterway. Shipping lines are diverting cargo to alternative ports like Salalah and Sohar in Oman, which now face significant congestion. The impact extends beyond fuel, threatening the supply of petrochemical feedstocks essential for plastics, which constitute 150-200 kilograms of a modern vehicle. Analysts project that a sustained disruption could increase these feedstock costs by 15-25%. Furthermore, the conflict jeopardizes the supply of critical materials for the semiconductor industry, including helium from Qatar, a leading global producer, which is crucial for heat management in chip fabrication and has no viable alternatives. South Korea, which supplies two-thirds of the world's memory chips, has voiced concerns about potential production disruptions.
