  The objective of this paper is to analyze the network topology of the Iranian overnight money market through methods of statistical mechanics applied to complex networks in order to assessing systemic risk. We investigate differences in the activities of 33 Iranian banks dividing into different four types between 2010-2015 by analyzing 66 montly adjacency matrixs. Using degree distribution analysis of the networks, we find that that Iranian interbank market network is scale-free network and cumulative degree, in-degree and out-degree follows the power-law distribution. In terms of the criterion of assortativity, the interbank market network of Iran is assortative and core-periphery with one or more banks as the money center. The results show that the Iranian interbank network is vulnerable to shocks and has high level of systemic risk. Also, in the event of failure, the most vulnerable group is to privatized and specialist governmental banks, and the private banks, due to the high volume of exchanges and net negative flows, can put a considerable systemic risk to the interbank market network.
