The US dollar gained after reports Trump was planning a 25 per cent tariff as opposed to 10 per cent and that an announcement is pending. The news reversed sentiment after investors had been cheered by overnight speculation the White House was trying to restart trade talks with China.
While the kiwi slipped it "remains contained in a very tight range" ahead of a rate decision from the US central bank and the Bank of England, said Mark Johnson, a private client manager at OMF.
"It's a big week of central banks," he said, adding the Federal Reserve is likely to reiterate that gradual rate rises remain appropriate. He said even though the BoE will likely lift rates "there is still massive policy divergence between the US and everyone else and that will continue to favour the US dollar."
The kiwi barely moved after domestic jobs data were largely in line with expectations and continued to show tepid wage inflation, adding to the view the Reserve Bank won't increase interest rates any time soon. The central bank will publish its latest decision and forecasts on August 9.
The kiwi climbed to 76.01 yen from 75.82 yen yesterday after the Bank of Japan made smaller adjustments to its policy programme than some investors had predicted.
