Abstract

Abstract:

The premise of preventing and defusing systemic risk is to accurately measure systemic risk. Through literature review， it is known that most of the existing research focuses on the measurement of systemic risk， and there is little literature evaluating the validity and accuracy of systemic risk. In addition， it is found that most of the literature mainly discusses the risk connectedness of financial institutions in the time domain， ignoring the connecting mechanism in the frequency domain. As a result， it focusy on two issues：（1） Backtesting the systemic risk of Chinese financial institutions to examine the effectiveness of MES and ΔCoVaR. （2） Based on the backtesting results of systemic risks， the risk connectedness among financial institutions is investigated by the quantile connectedness network in frequency.In response to the above problems， the following work is done： First， the MES and ΔCoVaR of 35 financial institutions in China are backtested by the unconditional coverage test， aiming to evaluate the effectiveness of MES and ΔCoVaR. Second， the early warning system is calulated to analyze the risk evolution of the financial system. Third， the quantile connectedness networks in the frequency domain through the quantile coherence method is proposed to explore the risk connectedness among financial institutions. Finally， the connectedness importance of financial institutions on specific frequency bands is measured.It is found that　（1） During the period of financial market crisis， commonly used systemic risk indicators such as MES， CoVaR， and ΔCoVaR fail to measure the systemic risk of financial institutions. （2） Compared with the short-term and medium-term connectedness layer， Chinese financial institutions have obvious extreme risk linkage effects in the long-term connectedness layer. （3） In the short-， medium-， and long-term， small- and medium-sized financial institutions such as Bank of Ningbo， Industrial Securities， and Dongfang Energy have connectedness importance. Therefore， the regulatory authorities should pay attention to preventing the risk of "too connected to fail" of small- and medium-sized financial institutions.

Key words: systemic risk, backtesting, financial institutions
