Summary

The national average price of diesel in the US has reached a record high of $5.85 per gallon due to the ongoing war with Iran, surpassing the previous peak set after Russia invaded Ukraine in June 2022. The price hike is expected to increase transportation and production costs for many products, including groceries, just weeks ahead of the congressional midterm elections. The American Automobile Association (AAA) reports that crude oil prices have risen to $90 per barrel due to continued volatility in the Strait of Hormuz, a major artery for global energy trade. US public opinion polls show that the war with Iran remains unpopular among voters, and rising costs of living are emerging as a top electoral issue.

Story summary

The national average price of diesel in the US reached an all-time high of $5.85 per gallon on Friday, surpassing the previous peak set in June 2022 after Russia invaded Ukraine. The American Automobile Association (AAA) reported this new record, which comes as President Donald Trump's administration continues to deal with the aftermath of the war with Iran. Diesel prices have surged since February when Iran responded to US and Israeli strikes by shutting down the Strait of Hormuz, a major artery for global energy trade. This has led to increased transportation and production costs for many products, including groceries. The high diesel price is also expected to impact the California economy, with prices nearing $7.71 per gallon in some areas. The war-driven disruptions to fuel supplies are driving up costs for small trucking fleets, family farms, and low-income households. Economists say the diesel spike is not unprecedented, but it comes at a time when voters are already sour on the economy ahead of November's midterm elections.
