America's employers delivered a surprising 115,000 new jobs last month despite an economic shock from the Iran war.

Hiring beat the 65,000 jobs forecasters had expected, though it decelerated from the 185,000 jobs created in March. The unemployment rate remained at a low 4.3 per cent, the Labor Department reported Friday.

The Iran war has caused the biggest disruption of global oil supplies in history and sent average US gasoline prices surging past US$4.50 a gallon this week. But the conflict hasn't done much damage to the American job market so far. And the import taxes — tariffs — that President Donald Trump imposed last year haven't turned out to be as high and as damaging as originally feared.
