The Impact of Non-Interest Income on Bank Risk in Chinese Commercial Banks

In the rapidly evolving economic landscape of Chinese commercial banks, the diversification of revenue streams beyond traditional interest income has emerged as a critical trend. Traditionally reliant on interest-based revenue, these institutions are increasingly focusing on non-interest income due to intensified market competition and the liberalization of interest rates. This study aims to investigate the impact of non-interest income on the risk profiles of Chinese commercial banks, a relationship that has been subject to both supportive and critical academic perspectives in recent research. This research employs a panel data econometric model analyzing data from thirteen publicly-listed Chinese commercial banks from 2015 to 2022. The paper explored variables such as non-interest income proportion, bank diversification index, and several risk measures like risk-adjusted return and the Z-Score for bankruptcy risk. Key findings indicate a complex relationship where non-interest income generally reduces bankruptcy risk and enhances risk-adjusted returns. Conversely, income diversification shows mixed effects; it appears to reduce risk in some metrics while potentially increasing it in others. The study concludes that while non-interest income plays a beneficial role in mitigating overall banking risk, the effects of diversification are nuanced and call for careful risk management. Banks are advised to balance their income streams and ensure that expansions into new non-interest income avenues align with their risk management capabilities. These insights contribute to strategic financial management within the evolving Chinese banking sector.
