The role of financial performance on the profitability of Indonesian Islamic banks

Purpose – This study aims to analyse the effect of non performing financing (NPF), capital adequacy ratio (CAR), financing to deposit ratio (FDR), and Bank Indonesia shariah promissory notes (SBIS) on Islamic banks’ profitability (ROA) in Indonesia.Methodology – The data set consists of 10 Islamic banks operating in Indonesia between 2017—2021. The secondary data was collected from the Financial Services Authority (Otoritas Jasa Keuangan, OJK). A method of panel data is used for this study by using Stata 17 to process the data.Findings – The estimation results showed that NPF partially has a significant negative relationship on ROA, both CAR and SBIS have a significant effect on ROA, while FDR does not affect ROA. Simultaneously, NPF, CAR, and FDR do not affect ROA. But NPF, CAR, FDR, and SBIS simultaneously have a positive and significant effect on the Islamic Bank's profitability (ROA) by the year 2017 – 2021.Implications – Islamic banks need to be more selective in providing financing to customers so that financing risks can be minimized. In addition, CAR and SBIS need to be increased or maintained so that the profitability level of Islamic banks can be maximized.Originality – This research tries to re-examine the effect of financial performance on the profitability of Islamic banks in 2017-2021.
