Abstract: The main aim of this paper is to investigate the relationship be-tween bank concentration and bank risk in the Jordanian banking industry from 2005 to 2016. While controlling for bank fundamen-tals and business cycle, we used two measurements to measure bank risk (Z-score and Non-performing loan ratio) and three meas-urements of bank concentration (Herfindahl–Hirschmann Index, Concentration Ratio and the Lerner Index). We applied the two-step Generalized Method of Moments (GMM) to analysis this relationship between concentration and risk. The empirical evidence shows bank concentration has a positive relationship with risk measured using non-performing loan ratio, and a negative relationship using Z-score. This suggests greater market power leads to greater risks, which in turn supports the concentration-fragility theory.
