US petrol prices jump 42.2% from year ago amid oil market turmoil

The average price of petrol in the United States was 42.2 percent higher in May than a year earlier, according to figures released by the US Transportation Department. 

The data came as oil prices rose about 1 percent on Tuesday to a one-week high, with markets closely watching developments in talks between Washington and Tehran.

The Strait of Hormuz remains a major factor in energy markets, with the near-total blockade disrupting roughly one-fifth of global oil and liquefied natural gas flows and contributing to a sharp rise in crude prices.
