Why has the size of the nominal GDP of Turkey shrunk to $850 billion in 2017 from around $930 billion in 2013 despite growth rates ranging from 3% to 8% during that period?

 Is it due to their currency depreciation? Is this sustainable?

I’m not familiar with Turkeys situation but if their currency has depreciated then that’s how they had growth yet a nominal GDP decrease. This is why Real GDP is a better figure for growth.

Sustainable probably not but it really depends but it’s an area I’m not going to touch since I’m not familiar with what’s going on with Turkey in the slightest.
