THere's one fact that people seem to have forgotten:
1USD=1.5TRY back in 2002.
Turkey has an inflation that's about 10% (reported, let's go with that).
1.1 ^ 16 * 1.5 = 6.8 - meaning 6.8TRY would be equivalent to 2002's dollar. US economy and dollar gained more strength in the meantime.
6.8 try/usd is not crazy. The previous exchange rate probably was.
