Granger causality analysis wasconducted to define the short-term causality among the variables. It is concluded: (a)there is a positive bidirectional causality between economic growth anddomestic credit provided by financial sector, (b) there is a positiveunidirectional causality from bonds to economic growth and (c) there is not arelationship between domestic credits and bonds. To investigate whether along-term relationship among the series, “Johansen Cointegration Test” wasemployed. The results indicated that there is a long-term relationship betweenthe economic growth and financial development. By implementing “VarianceDecomposition Technique”, it is concluded that economic growth is explained by 67% GDP, 8% BONDS and by 23%CREDIT.  The results of this research support theMutual Interaction Hypothesis that asserts a bidirectional relationship betweenFD and EG and in this context, financial deepening has an important place interms of sustainable economic growth.eninfo:eu-repo/semantics/openAccessEconomic GrowthFinancial DevelopmentVar Granger Causality AnalysisJohansen Cointegration Analysis.Article8197125560076
