Turkey's economic confidence index increased by five points in March, increasing from 91.50 points to 96.1 points, according to the data released by the Turkish Statistical Institute (Turkstat) on Thursday.

The retail trade reading was the only sub-index in negative zone, suffering 0.3 points from the previous month to 97.7 points.
