We, at FxWirePro, have been calling for selloffs in the dollar for quite some time now. This chart from Bloomberg, shared by Paul Dobson shows the continued weakness in the green buck. The dollar has given up all of its post-Brexit referendum gains and now is back to pre-Brexit lows.
Current rate hike path, unless upgraded, is much softer than estimated back in 2014 and not sustainable for the dollar to remain strong.
