“Overarching concern over tightening global oil supplies, in advance of U.S. trade sanctions on Iran, have helped WTI rise $2.47 a barrel in just the past week, while Brent crude oil picked up nearly $4 in value to achieve thresholds not seen since November, 2014,” Patrick DeHaan, senior petroleum analyst for GasBuddy.com, said in a prepared statement. “Looking ahead, the squeeze in global supplies will almost certainly put gasoline prices under pressure and provide a strong basis for further increases at the pumps at a time when drivers are accustomed to seeing prices soften. Short of producing countries suddenly finding a million spare barrels of oil over the month of October, drivers should brace for even more rising prices over the next several weeks.”
