Markets fall in reaction to Trump turmoil

European and Asian equity markets slumped in the wake of the worst day in eight months for U.S. stocks as the political crisis engulfing U.S. President Donald J. Trump's administration drove investors to the safety of bonds. Shares across Europe extended declines following new revelations about undisclosed contacts between Trump's campaign and the Kremlin. The Justice Department Wednesday appointed a special counsel to probe Russia's role in the 2016 election, deepening a crisis fueled by reports Trump asked FBI Director James Comey in February to halt an investigation before firing him last week. Treasury yields dropped to the lowest in a month, while crude slumped the most in two weeks. The dollar benefited from weakness in emerging-market currencies as political turmoil in Brazil added to the chaos in Washington. As the confusion surrounding Trump threatens to derail the policy agenda that helped push global equities to records as recently as Tuesday, a gauge of U.S. stock volatility surged the most since the U.K. voted to leave the European Union last June. Many of the trades sparked by the president's November election have now reversed, with the dollar all but erasing its post-election rally. "The market will revert to much higher volatility and this could be the start of it," said Richard Haworth, chief investment officer of 36 South Capital Advisors, a London-based hedge fund which bets on rising price swings. "The sharp move this week reflects how short volatility the market was -- how complacent."
