Sparta Commodities' Head of Research, Neil Crosby, stated in a report that U.S. oil exports will soon be significantly constrained by inventory levels, as stocks are already notably low. Once WTI strengthens relative to Brent, and U.S. gasoline and diesel strengthen relative to their European counterparts, U.S. exports should decline. Before U.S. inventories recover, the price spreads for U.S. heating oil and gasoline could widen substantially. Since the outbreak of the Iran war, high U.S. oil exports have been one of the primary factors suppressing global oil prices.
