The relationship between selected determinants of market risk and the financial performance of participation banks in Turkey: A comparative study with conventional banks

The main purpose of this study is to investigate the relationship between the selected determinants of market risk with the financial performance of participation banks in Turkey and compare it with conventional banks. The market risk determinants are interest rate (INT), the exchange rate (FX), inflation (INFL), and GDP per capita. The financial performance determinants for both participation and conventional banks are, return on assets (ROA) and return on equity (ROE). There are secondary data used for 3 participation banks and 5 conventional banks performing in Turkey. The time period of this study is from the year 2010 to 2019. The tests applied in the study are panel data tests like the Augmented Dickey-Fuller Unit Root test, Johansen co-integration test, and Granger Causality test by using the E-views program. The study results conclude that interest rate, exchange rate, inflation rate, and GDP per capita have a highly significant positive long-run relationship with return on assets and return on equity of participation banks in Turkey. However, the variables are not significantly related to each other in the short run in the interval time of lag 2. There is less significant positive effect shown for conventional banks compared to participation banks in the long run. It is recommended for future studies to increase the sample size and include more determinant factors to determine the financial performance of participation and conventional banks in Turkey
