The closure of the Strait of Hormuz has restricted the flow of energy to global markets, severely impacting oil prices. As a direct result of rising oil prices, gas prices have also risen worldwide, including in the United States.

Although the average prices of gas and diesel have risen in the U.S. to $4.51 per gallon of gas and $5.63 per gallon of diesel as of May 18, the rise in energy prices has been substantially more noticeable in California. On the same day, California reported average gas prices of $6.15 per gallon for regular and $7.41 per gallon for diesel.
