Dollar sales have accelerated since the Fed last week signalled it would cut interest rates before year-end on mounting worries about the fallout from U.S. President Donald Trump's trade disputes with China and others. United States and China have waged an 11-month trade war marked by tit-for-tat tariffs on hundreds of billions of dollars of each others' goods, roiling financial markets, disrupting supply chains and crimping global economic growth prospects.
The markets now await the outcome of the U.S-China talks at the G20 summit.
"The focus remains on trade wars as markets await the G20 summit with bated breath," said Bianca Botes, a Treasury partner at Peregrine Treasury Solutions. "The outcome of U.S. China trade talks will set the tone."
