“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.
