Oil prices edged lower after five straight trading days of gains, with WTI crude oil falling below $82 a barrel and Brent crude oil briefly dropping below $87, Gate market data showed. The pullback came as traders waited for signs of progress on reopening the Strait of Hormuz, a key shipping route for global energy flows. The International Energy Agency said the global oil market is facing a supply gap of 1.8 million barrels per day this quarter, more than double its previous forecast, underscoring continued tightness in crude availability. In the United States, gasoline and diesel prices have also climbed to new highs for this time of year.
