Iran’s effective shutdown of the Strait of Hormuz has locked up 20% of the world’s oil. But the locked-down Strait of Hormuz has restricted access to other goods, too. HeliumMore than a quarter of the world’s helium comes from Qatar and travels through the Strait of Hormuz, according to the US Geological Survey. For example, most of Asia’s naphtha – a chemical used in paints and cleaners comes – through the Strait of Hormuz, according to the Independent Commodity Intelligence Services. The war has already prompted other regions that make those materials, including Latin America, to make more, and they’ve responded to increased demand by raising their prices, according to S&P Global.
