The dollar index (DXY00) today fell to a new 4-month low and is down -0.61%.
The dollar is being undercut by speculation that the US might coordinate FX intervention with Japan to boost the yen, which would dovetail with Mr. Trump's apparent view that a weak dollar is good for the US as a stimulus to US exports. US authorities reportedly contacted market participants last Friday to check dollar/yen prices, a possible precursor to intervention.
