Americans have paid out $59 billion more on fuel since President Donald Trump started his war against Iran — and the extra costs have already eaten up the boost in this year's average tax refund, according to a report Friday.
Moody's chief economist Mark Zandi estimated that the increased spending amounted to about $450 per U.S. household, "made up mostly of gasoline, then there's a diesel cost and an implied jet fuel cost in those higher airline fees,” CNBC senior economics reporter Steve Liesman said on the cable network's Squawk Box show.
