BEIJING -- Global shares fell sharply Monday after China let its currency to sink to an 11-year low against the dollar, fueling concern that Beijing is using the yuan as a weapon in an escalating tariff war with U.S. President Donald Trump.
Market benchmarks in London and Paris fell more than 2% in early trading while Tokyo closed down 1.7% and Hong Kong declined almost 3%. Frankfurt, Shanghai and Sydney also retreated.
Wall Street was also poised for a sharp downturn, with Dow and S&P futures down about 1.5%.
China's central bank allowed the yuan's exchange rate to sink below the politically sensitive level of seven per dollar. That level has no economic significance per se but might fuel trade tensions with the U.S. government, which complains a weak Chinese currency swells the country's exports and hurts foreign competitors.
"Markets will brace for trade tensions to boil," said Vishnua Varathan of Mizuho Bank in a report.
The People's Bank of China blamed the decline on "trade protectionism," a reference to Trump's tariff hikes in a fight over Beijing's trade surplus and technology policies. Trump rattled financial markets with a threat Thursday to raise duties on additional Chinese imports.
Beijing appears to have decided "the currency is now also considered part of the arsenal to be drawn upon," said Robert Carnell, analyst at bank ING.
London's FTSE 100 fell 2.2% to 7,247 and Frankfurt's DAX lost 1.8% to 11,661. France's CAC-40 declined 2.1% to 5,243.
