Oil prices were lower today, trading down on higher gasoline inventories and lower product demand. Gasoline futures also sank today. “If you don’t need the gasoline, then you don’t need the crude oil to make the gasoline, and that’s the math that’s killing crude oil right now,” said Robert Yawger, executive director of energy futures at Mizuho. Trading volumes have been thin and prices remain volatile. The ECB today followed other central banks and raised rates today, stoking further demand worries.WTI traded down $3.53 or -3.5% to close at $96.35. Brent traded down $3.06 or -2.9% to close at $103.86.
