However, the systemic financial risk spillover effect of commercial banks is one of the main causes of financial crises. This paper selects the stock price data of listed commercial banks and studies the systemic financial risk spillover effect of individual commercial banks and the entire banking industry using value at risk and conditional value at risk methods. Empirical research reveals that commercial banks can indeed transmit financial risks to the financial system, and this effect becomes more pronounced during economic crises.
