Abstract: This study investigates the relationship between interest rate, interest rate volatility, and banking sector development in 12 emerging market economies located around the world. For this purpose, panel data analysis was conducted using annual data from 1980 to 2014. In parallel to the financial development literature, which asserts that banking sector development, as a broad and complex concept, cannot be measured by a single indicator, this study adopts a set of measures of banking sector development. The empirical results reveal that while interest rate has a positive impact on all banking sector indicators, this relationship weakens at higher interest levels, showing a concave relationship between interest rate and banking sector development. In addition, the empirical results provide evidence that interest rate fluctuations have a negative impact on most banking sector development (BSD) indicators, suggesting that the banking sectors of emerging countries are vulnerable to interest rate risks. Furthermore, all measures of the banking sector indicators are positively affected by economic growth rates, while this association weakens at higher levels of income, confirming a nonlinear relationship. Thus, the results have important implications for policymakers in improving the banking system and promoting the economic growth of these emerging economies.
