The won swung to a loss as the South Korean government warned about the currency’s ascent, the latest Asian nation to push back against foreign-exchange strength as investors jump on emerging-market assets.
The currency fell as much as 0.7 percent to 1,069.80 per dollar, reversing an earlier gain to 1,058.80. South Korea will take steps "sternly" in case of one-sided moves in the won as the dollar weakens globally, said an official at the nation’s FX authority, who asked not to be identified because of internal policy.
