"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, GasBuddy.com senior petroleum analyst.
"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," DeHaan said.
