Global stocks, dollar tumble as Trump sparks global trade war fears

The spectre of a global trade war sent world stocks tumbling towards a 2.5 percent weekly loss on Friday, and left bruised investors reaching for the traditional antidotes - government bonds, gold and the Japanese yen.

The falls came after U. S. President Donald Trump said the United States would impose tariffs of 25 percent on imported steel and 10 percent on aluminium, sparking concerns of retaliatory moves from major trade partners China, Europe and neighbouring Canada.

Europe's STOXX 600 index fell over 1.5 percent led by a near 5 percent slump from world's biggest steelmaker ArcelorMittal SA and 2.5 - 6 percent drops from the region's carmakers worried that they might be next.
