The dollar declined against a basket of major currencies on Friday, settling near a one-month low, as the threat of a looming trade war between the U.S. and China intensified.
President Donald Trump signed a memorandum that would implement tariffs on up to $60 billion in imports from China on Thursday.
The tariffs largely focus on technology sector goods and were intended to penalize China for, according to the Trump administration, stealing intellectual property.
In response, China on Friday proposed a list of 128 U.S. products as potential retaliation targets, according to a government statement.
Adding to risk-averse sentiment, Trump named John Bolton as his National Security Adviser late Thursday. Bolton is known for calls to use military force against both North Korea and Iran.
The U.S. dollar index, which measures the greenback’s strength against a basket of six major currencies, ended down 0.4% at 89.10 by close of trade. It fell to its lowest since Feb. 19 at 88.98 at one point.
For the week, the index lost roughly 1.3%, its worst weekly performance in over a month.
The dollar was already on the back foot a day earlier after the Federal Reserve gave guidance on the pace of interest rate rises that was less aggressive than some investors had expected.
The yen, often viewed as a safe-haven currency in times of market turbulence and economic uncertainty, rose to a 16-month high against the dollar. The greenback was last down 0.5% at 104.74.
On the week, the yen rallied 1.1% against the buck.
The dollar also slipped 0.2% against the Swiss franc, another currency bought in times of market uncertainty.
Meanwhile, the British pound inched higher after Bank of England rate-setter Gertjan Vlieghe said that interest rates will probably need to rise once or twice a year over the next few years, comments that are likely to help cement investors' expectations of a BoE rate hike in May.
The euro was also a shade higher against the dollar, with EUR/USD gaining 0.4% to 1.2352.
In the week ahead, rhetoric rather than economics could be the main driver of sentiment, as investors watch further developments amid a brewing trade war between the U.S. and China.
