In the short-term, don't be surprised to see Euro take center stage. Brexit(Oct2019??) and it's ramifications, along with the sustainability problems of Euro will once again be forefront. But the Fed just lowered IR's!?!?!... It's doesn't matter.
No one respects the Euro outside of people who trade with and within the zone. It's just a necessary evil. Do you think anything coming out of the Eurozone besides bureaucrats will ever dominate world trade? LOL.
