Oil prices steadied on Friday after almost a week of sharp rises as Hurricane Irma, one of the most powerful storms in a century, drove towards Florida after tearing through the Caribbean. Irma is the second major hurricane to approach the United States in two weeks and has already killed 14, flattening whole islands. Its predecessor, Harvey, shut a quarter of U.S. refineries and 8 percent of U.S. oil production. “Hurricanes can have a lasting effect on refinery and industry demand,” said Eugen Weinberg, head of commodities research at Commerzbank in Frankfurt. “The impact of the forces of nature on U.S. oil production should not be overestimated – nor should their impact on demand be underestimated.”

Gasoline surged to the highest in two years and oil declined as flooding from Tropical Storm Harvey inundated refining centers along the Texas coast, shutting more than 10 percent of U.S. fuel-making capacity. Motor fuel prices rose as much as 6.8 percent, while New York oil futures slipped 0.9 percent. Harvey, the strongest storm to hit the U.S. since 2004, made landfall as a hurricane Friday, flooding cities and shutting plants able to process some 2.26 million barrels of oil a day. Pipelines were closed, potentially stranding crude in West Texas and interrupting gasoline supply. Click Read More below for more of the story.
