The dollar tumbled on Monday to its lowest level in three years as investor confidence in the U.S. economy took another hit over President Donald Trump's attacks on the Federal Reserve chairman, potentially putting the central bank's independence under threat.

The benchmark dollar index has fallen roughly 5 percent since early April, when Trump roiled markets with his sweeping tariffs.

The dollar index (DXY00) today is up by +0.57%. The dollar is climbing today due to an easing of the harsh trade rhetoric against China after President Trump said he plans to be “very nice” to China in any talks and that tariffs will drop if the two countries can reach a trade deal.
