Dollar mired in US economic weakness and trade limbo

SINGAPORE (Reuters) -The dollar was headed for a weekly loss on Friday, undermined by signs of fragility in the U.S. economy and as trade negotiations between Washington and its trading partners made little progress despite a looming deadline. Key for markets will be the U.S. nonfarm payrolls report later on Friday, which will draw greater scrutiny after a slew of weaker-than-expected economic data this week underscored the headwinds from President Donald Trump's tariffs. Currencies were taken on a round trip overnight, with most surging against the dollar initially on optimism that Trump and Chinese leader Xi Jinping spoke in a more than one-hour-long call, before paring some of their gains.
