Amid ongoing disruptions from the Iran war, including the Strait of Hormuz closure and attacks on smelters, this Marketplace episode examines rising commodity prices, their ripple effects on businesses and energy use, alongside market gains, a major corporate deal, and indicators of household economic strain.

Aluminum Shortages and Price Surges

Aluminum prices have risen about 10% since the war began, per CRU Group, on top of 50% U.S. tariffs on imports dating to 2018. Factors include smelter attacks, the Hormuz blockage affecting supply chains, and higher energy costs for production.

Show Notes

One glaring result of President Trump’s war on Iran, one month in? High oil prices. If fuel stays expensive, the cost could ripple through the global economy. Analysts think the market for electric vehicles in the U.S. could see a boost, for example, as gas prices shoot up. And countries in Asia may reopen coal production plants as crude oil becomes scarce. Also in this episode: Aluminum prices spike, Unilever sells off its food brands to a spice giant, and plasma centers see more middle-class donors.
