The dollar tumbled on Monday as investor confidence took another hit over President Trump's attacks on Fed chair Jerome Powell.

The president amps up attack against US central bank boss calling him "a major loser" for not lowering interest rates.

Mr Trump’s ultimate desire is not in doubt. The Fed has cut rates by only a percentage point since September, to 4.25-4.5%. Mr Trump, like most businessmen, dislikes tight money, and covets the lower rates in Europe and elsewhere.
