“Gas prices are rising across much of the nation as Iran has continued to threaten closing the Strait of Hormuz, a vital waterway for global oil shipments,” said Patrick DeHaan, a senior petroleum analyst for GasBuddy.com. “Think back to the days following the start of the crisis in Libya — an event that also rattled energy markets. We’re seeing similar emotions play out even though there hasn’t yet been a disruption to supply. I would blame emotion for the recent uptick in gasoline prices. Nothing else.”
