The Influence of Treasury Single Account Implementation on Public Sector Performance: A Case Study of Selected Parastatals in South East Nigeria (2010-2019)

This study delved into the effect of Treasury Single Account (TSA) on public sector performance in selected parastatals in South East Nigeria (2010-2019). The broad objective of this study was to ascertain the effect of Treasury Single Account (TSA) on public sector performance in selected parastatals in South East Nigeria. Consequently, four research questions and four hypotheses were formulated to guide the study. Survey design was adopted for the study. Area of the study is South East Nigeria, population of the study was 1,548 staff drawn from Boards of Internal Revenues (BIRs) of the five States in South East. Stratified random sampling was used to derive 713 respondents for the study. Instrument for data collection was self-structured questionnaire. Mean and standard deviation was used to answer research questions while ANOVA and Z-test statistic was used to analyze hypotheses. The result based on empirical analysis revealed that treasury single account had positive effect on fraud detection in Parastatals in South East Nigeria, treasury single account had positive effect on revenue mobilization in Parastatals in South East Nigeria, treasury single account had positive effect on blockage of financial leakages in Parastatals in South East Nigeria and treasury single account had positive effect on financial savings in Parastatals in South East Nigeria. Thus, the study concluded that fraud detection, revenue mobilization, financial leakages and financial savings have been affected in Parastatals in South East Nigeria as result of Treasury single account (TSA). Based on the findings, the following recommendations among others were proffered: Government should ensure timely release of operational funds to encourage MDAs to support the TSA Policy. This can be achieved through the use of treasury bills (T-bills) or other short-term borrowing instruments aimed at offsetting the impact of TSA implementation on government cash flows and there should be full implementation of TSA in all states ministries, Departments and Agencies (MDAs). Partial implementation in many states as was observed by the researcher during field work should be discouraged. The gains of TSA cannot be overemphasized.
