The dollar slipped to a more than one-week low against the yen on Wednesday, pressured by worries over possible delays to President Donald Trump's tax reform plans.
U.S. House of Representatives Speaker Paul Ryan on Wednesday left the door open to a possible delay in implementing a huge corporate tax cut, following a Washington Post report that his fellow Republicans in the Senate are exploring the option.
Any potential delay in the implementation of tax cuts, or the possibility of proposed reforms being watered down, would tend to work against the U.S. currency, analysts said.
"Anyone who has been long the dollar has been really vulnerable to headlines. We have seen a lot of traders leave the party on any sort of inkling of bad news," said Lennon Sweeting, chief market strategist at XE in Toronto.
The dollar was down 0.14 percent to 113.84 yen, after having fallen as low as 113.4 yen, earlier in the session.
