俄罗斯银行间市场的违约传染风险

Default contagion risks in Russian interbank market

A. V. Leonidov, E. L. Rumyantsev

摘要:

研究了俄罗斯银行间市场违约传染的系统性风险。分析是基于考虑蝴蝶结结构的加权有向图描述的银行间贷款的结构。基于经验数据,建立了一个银行间传染的概率模型,该模型明确考虑了反映相应节点(借款人、贷款人、借款人和贷款人同时)功能性的经验蝴蝶结结构、银行间网络的度分布和离散性。用该模型计算的传染相关系统性风险特征与显式压力测试结果一致。

英文摘要:

Systemic risks of default contagion in the Russian interbank market are investigated. The analysis is based on considering the bow-tie structure of the weighted oriented graph describing the structure of the interbank loans. A probabilistic model of interbank contagion explicitly taking into account the empirical bow-tie structure reflecting functionality of the corresponding nodes (borrowers, lenders, borrowers and lenders simultaneously), degree distributions and disassortativity of the interbank network under consideration based on empirical data is developed. The characteristics of contagion-related systemic risk calculated with this model are shown to be in agreement with those of explicit stress tests.
