The dollar was trading 0.02 percent lower vs the Japanese yen at 106.54 as of 06:10 GMT on Wednesday, with investors digesting inflation data while still awaiting fresh figures.
The American currency came under pressure as investors flew to safe-haven assets after the US Government announced that Secretary of State Rex Tillerson was fired on Tuesday.
The US dollar index, which measures the greenback against six major currencies, was trading 0.54 percent lower at 89.19 by the time of this writing.
US President Donald Trump said there were differences with Tillerson over the Iran nuclear deal. Tillerson will be replaced by the Central Intelligence Agency Director Mike Pompeo.
“When you look at the Iran deal, I think it's terrible. I guess he thought it was OK,” said the Republican leader. “I wanted to either break it or do something and he felt a little bit differently, so we were not really thinking the same.”
This is not the first political turmoil weighing on the Trump administration. Only a week ago, Trump’s top economic advisor Gary Cohn resigned following Trump’s decision to impose tariffs on steel and aluminium imports, with the exemption of Canada and Mexico.
