I figure TPTB think Europe has been basking long enough, with a falling Euro since June 2014, the month they started running the dollar up, to push the other currencies down. Everything is priced in dollars. Starting in early 2017, it looks like they reversed the stimulation FROM Europe back to the USA.
Its plain to see in this chart. That up move in 2014 HAD to be a PTB controlled manual adjustment.

I hear car sales are falling. So all that momentum of the stimulation the USA had during the 80 dollar index, is running out of steam. Don’t be surprised if it gets obvious that the US economy is starting a slowdown just as TPTB continue dropping the Dollar back towards 80. Always long delays between action and the reaction.
