President Donald Trump triggered a slide in the US dollar on Wednesday

after he complained the currency had risen too high,

in part because of what he said was confidence in his own presidency.

Mr. Trump also revealed a major policy U-turn,

saying that the US government would not label China a currency manipulator

and declined to shut down the idea of re-nominating Janet Yellen as Fed chair

despite campaign pledges not to offer her a second term.

The dollar index fell as much as 0.8% in the wake of Mr. Trump's remarks.

Although the currency stabilized early on Thursday,

it was still well below levels before Mr Trump's comments.

The question remains after Mr. Trump's remarks

on whether they will be followed by any actions.
