The impact of expansion of Turkish treasury single account system on public financial management in Turkey

Today, the public cash management has gradually been managed more actively and professionally. Some essential reforms should be enacted to transit from traditional to modern cash management approach, extending the scope of Treasury Single Account (TSA) comes first among these reforms. TSA, in the good practices case, has an extensive spectrum including almost all public resources, but it just covers the units of central and local administration in Turkey. In this regard, the scope of TSA in Turkey should be extended to use public resources more efficiently by collecting them in a single center, therefore avoiding unnecessary borrowing and evaluating public funds better through economies of scale. In the study, the modern cash management is examined at first, then the theoretical framework of TSA is examined. Then, applications of TSA in Turkey over the time are reviewed in chronological order. Moreover, finally, a new extended scope of TSA covering other public institutions is proposed. The study which assesses the coverage of TSA in Turkey with a new perspective and aims to propose an ideal TSA coverage is believed to contribute to the efforts for the extension of the TSA system as a part of the modernization of the cash management in Turkey.
