….. ranging from the much prophesied death of the dollar to Treasury Secretary Steve Mnuchin’s actively dissing the dollar at every opportunity he gets — one thing we know: The decline started in late December 2016, after the index had peaked at 93.50. And it has not abated since. With the index currently at 82.47, it has fallen nearly 12% over those 14 months.
The Fed keeps an eye on the dollar. A weak dollar makes imports more expensive and, given the huge trade deficit of the US, adds to inflationary pressures in the US.
