The U.S. dollar extended a recent downtrend on Monday that saw it lose further ground against most of its major rivals, as President Donald Trump over the weekend delivered his latest salvo against Federal Reserve monetary policy.

On Sunday, Trump said the stock market and U.S. economic expansion would be stronger if not for the Fed, leveling a fresh assault against the central bank run by Chairman Jerome Powell, even as the institution has adopted a wait-and-see approach to further interest-rate increases and is set to end the unwind of its $4 trillion balance sheet.
