“Gasoline and diesel prices continue to climb to multi-year highs as the effective closure of the Strait of Hormuz curtails the flow of millions of barrels of crude oil each day,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The situation remains highly volatile and unpredictable, but upward pressure on fuel prices is likely to persist as long as the continued disruption in the Strait constrains global oil supplies. We’re likely to see the national average for gasoline push beyond the $4-per-gallon mark, while diesel could approach $6 per gallon and potentially set new records if conditions fail to improve. Americans have already spent nearly $8 billion more on gasoline over the past month, a trend that poses growing risks to the broader economy, while surging diesel prices may begin to reaccelerate inflation.”
