LONDON, Jan 17 (Reuters) - Stocks, bond yields and the dollar fell on Tuesday, while gold rose as investors drew in their horns in response to comments on the dollar from U.S. President-elect Donald Trump and ahead of a speech on Brexit from British Prime Minister Theresa May.
Trump's remarks that the dollar is too strong and hurting U.S. competitiveness pushed the greenback down across the board, even against sterling, which is under heavy pressure as May is expected to confirm her "hard Brexit" stance later on Tuesday.
Britain's pound was higher on the day but still close to Monday's three-month lows, while the Japanese yen hit a six-week high as investors sought shelter from the mounting political risk of a week that also includes Trump's inauguration.
Investors are seeking clarity on his policies after campaign pledges on tax cuts and government spending helped lift stocks and the dollar and were deemed positive for economic growth.
In remarks to the Wall Street Journal published on its website late on Monday, however, Trump said U.S. companies could not compete with China "because our currency is too strong. And it's killing us".
Safe-haven investments such as gold and government debt also gained.
"Sterling is trading higher ahead of Theresa May's speech on Brexit but we're expecting a wild ride for the pound today," said Neil Wilson, senior market analyst at ETX Capital.
"These gains are largely down to dollar weakness, however, and gold has risen amid a bid for safer assets ahead of this speech and Donald Trump's inauguration on Friday."
The dollar was down a third of 1 percent against a basket of currencies .DXY , and down 1 percent against the Japanese yen to a six-week low of 113.04 JPY= .
The euro was up 0.6 percent at $1.0665 EUR= , while sterling rebounded 1 percent to $1.2160 GBP=D4 . The prospect of Britain losing access to the single market drove sterling as low as $1.1983 on Monday, its weakest, barring an Oct. 7 "flash crash", for more than three decades.
Prime Minister May speaks at 1145 GMT and is expected to say Britain will not seek a "half in, half out" deal when it leaves the European Union. She will set out 12 priorities for talks with the EU, her office said, and media reports said these would include an indication she is prepared for Britain to leave the bloc's single market. have taken back all of the move from yesterday morning. The speech has been so well telegraphed that I think people (betting against sterling) realise that is dangerous," said Richard Benson, co-head of portfolio investment with currency fund Millennium Global in London.
