Within the NF, the EU Acquis has been categorized under 35 chapters of which 17th is on Economic and Monetary Policy. Capter 17 was opened to negotiations with the Intergovernmental Accession Conference on 14 December 2015.

To achieve this end, after presenting a brief info on the accession negotiations, a descriptive analysis about Turkey’s performance against thresholds will be made, and finally policy recommendations will be provided.
