It employs quantile regression calculations, conditional value-at-risk, and Granger causality tests to investigate the spillover risk of these banks. The research results indicate that the spillover risk from the four major state-owned banks in China has shown a year-on-year decreasing trend, but the overall risk remains relatively high. Some of the commercial banks with different ownership structures exhibit a wider range of volatility, requiring special attention. Based on these findings, the article recommends three main actions: firstly, the need to construct a systemic risk monitoring and early warning system suitable for China’s level of financial development;secondly, emphasizing a focus on and strengthening the regulation of systemically important banks and institutions;and thirdly, not disregarding the potential for smaller banks to trigger systemic risks.展开更多

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. Based on the above, this paper calls for strengthening the following aspects: enhancing regulation and regulatory cooperation, establishing forward-looking risk alert mechanisms, and improving risk management capabilities in order to maintain the healthy and stable development of China’s financial system.展开更多
