The closure of the Strait of Hormuz by the Iranian government has been the primary focus on its impact on global oil flows. Approximately 20% of global crude supplies exited the Persian Gulf via the Strait daily, and this has led to a price spike for oil and refined products like gasoline and diesel, along with shortages in importing countries. However, many other key products also need to transit the Strait to flow into the world market. The price spike in gas prices, which hit millions of Americans, is seen as a de facto regressive tax that hits those who can least afford it. Other key products such as liquefied Natural Gas, fertilizer, and helium also face significant impacts due to the closure. The loss of half the world's supply of fertilizer will result in food shortages and increased costs for farming operations.
