To this end, the present study investigated the impact of oil price fluctuations on lending power of specialized banks in Iran using seasonal data from 1999 to 2018 using by Generalized Method of Moments (GMM). The results of this study indicate that during the period under review, oil price fluctuations has been a negative and significant effect (coefficient of -0.01) on the credit growth of specialized banks.
