The dollar slumped Thursday in the wake of dovish Federal Reserve minutes highlighting concern over inflation and crumbling corporate support for US President Donald Trump.
The greenback was back below 110 yen as safe haven assets were reinvigorated, with Asian equities treading water to broadly hold gains from a rally earlier in the week on easing tensions over North Korea.
New York stocks finished higher despite developments in Washington, with the Dow rising above 22,000 even as Trump disbanded a pair of business advisory boards after several chief executives resigned over his widely criticised response to a white supremacist rally in Charlottesville.
Tokyo stocks slipped by the break on Thursday with banks in retreat after Fed policymakers hinted at a slower pace of interest rate hikes at their July meeting, with shares also dragged lower by the stronger yen.

- 'Crumbling business support' -
"US investors shrugged off Fed fretting over low inflation, weaker than forecast housing data and crumbling business support for the White House to maintain stock market levels within one percent of all-time highs," said Michael McCarthy, chief market strategist at CMC Markets.
"USD weakness followed the release of (Fed) minutes that indicated 'many' members feared inflation will stay lower for longer."
The dollar was also put under pressure by the fresh turbulence in Washington.
"If you thought the president lacked the necessary key back room operators to implement the White House economic agenda, well things just got worse," said Oanda's Stephen Innes.
"Predictably the dollar sagged, and safe havens were back in vogue."
