I was aimlessly surfing wikipedia and stumbled upon a list of European GDP numbers over the last few years.
What caused the decline between 2014 and 2015 numbers. You can see a clear decline all across the board between those years while the markets where slowly climbing over all.
Did I miss a crisis, am I overlooking a reason or does wikipedia have it's head up it's ass and fucked up the numbers?
I'd also like to point out you can clearly see the economic impact of the embargoes on Russia:
2013 - 2,230.624
2016 - 1,267.754
So yeah it's hurting.
I don't have a researched answer for you, but by looking at the numbers on wikipedia, it is done in USD. I believe the dollar has been strengthening a lot against other currencies over the past few years so they might account for some of the change.
