This study contributes to the banking literature by examining the effect of bank liquidity creation on bank risk-taking behaviors in Vietnam - a transition economy. Our data sample comprises 367 observations of 33 Vietnamese commercial banks from 2009 to 2020. We employ the Bias-corrected Least-Squares with Dummy Variables (LSDVC) estimation, which performs better than other dynamic estimators in small and unbalanced panel samples. In this research, bank risk primarily represents non-performing loans (NPLs). Empirical results show that bank liquidity creation significantly reduces NPLs. Otherwise, bank funding diversification significantly increases NPLs in Vietnamese commercial banks. Our findings are robust to alternative measurements of liquidity creation and bank risk. Additionally, we show the moderating role of bank scale in the effects of liquidity creation and funding diversification on bank risk-taking in Vietnamese banks. Our paper is the first research investigating the influence of liquidity creation on bank risk-taking in the specified situation of a transition economy. Besides, it provides empirical evidence to fill the existing research gap. Further, this study provides a list of implications for bank managers and policymakers to manage credit risks and improve the stability of the Vietnamese banking system.
本研究通过考察银行流动性创造对越南这一转型经济体中银行风险承担行为的影响,为银行文献做出了贡献。我们的数据样本包括2009年至2020年期间33家越南商业银行的367个观测值。我们采用带有虚拟变量的偏差校正最小二乘法(LSDVC)估计,在小样本和非平衡面板样本中,该方法比其他动态估计方法表现更好。在本研究中,银行风险主要表现为不良贷款(NPL)。实证结果表明,银行流动性创造显著降低了不良贷款。否则,银行资金多元化显著增加了越南商业银行的不良贷款。我们的研究结果对于流动性创造和银行风险的替代度量是稳健的。此外,我们展示了银行规模在流动性创造和资金多元化对越南银行风险承担影响中的调节作用。我们的论文是第一项在转型经济体特定情况下研究流动性创造对银行风险承担影响的研究。此外,它提供了实证证据来填补现有研究空白。此外,本研究为银行经理和政策制定者管理信贷风险以及提高越南银行体系的稳定性提供了一系列启示。
