This method can describe both long run and short run equilibrium between banking profitability and macroeconomic variables.Findings – The results point out that in a long run model, sharia banking's profitability is more resistant to macroeconomics shock than conventional's. Then, in a short run model, sharia's ROA and conventional's ROA face different effects of economic growth, exchange rate, and global crisis. Sharia's NPM is more affected by macroeconomic variables than conventional's.Originality – This study used an ARDL model to develop a dynamic relation between macroeconomic variables and dual bankings profitability
