Abstract: Purpose - This study provides empirical evidence for the first time on how different measures of monetary policy affect banking profitability in Ghana. Design/methodology/approach - Providing empirical evidence on how different measures of monetary policy affect banking profitability in Ghana using 29 banks for period between 2006 and 2016, new monetary indexes are developed and a robust panel random effect models is employed with year effect controls. Findings - The results show that while increase in monetary policy basis point reduced banking profitability, average monetary policy rate stimulated banking profitability. Interestingly, the monetary policy basis point and rate indexes developed reduced and enhanced banking profitability, respectively. While these results may sound contradictory, they have both theoretical and empirical backing. Thus, basis point increments serve a monetary policy tightening condition which leads to higher loan prices, lower borrowing and declined profitability in the short run. However, in the long run, banks adjusted their loan prices and deposits to reflect basis point changes in their favor, hence the positive effect of average monetary policy rate on banking profitability. Additionally, monetary policy easing which represents decline in monetary policy basis point and rate enhances banking profitability. Practical implications - These findings imply bank managers may take advantage of monetary policy easing to maximize profits in the banking sector of Ghana. Also, the monetary policy committee must be mindful of monetary policy tightening through basis point change since upward basis point increments reduce banking profitability. Originality/value - This study provides empirical evidence for the first time on how different measures of monetary policy (developing indexes from monetary policy basis point and monetary policy rate) affect banking profitability in an emerging economy as Ghana.
