Abstract

This empirical study investigates whether a strong bank culture may help strengthen, weaken, or have no effect on the relationship between regulatory capital and liquidity creation. Using a machine learning approach and banks’ 10-K reports, we first measure the corporate culture of selected bank holding companies (BHCs) in the United State (U.S.) over the period between 1995 and 2019. We find that bank culture does affect the link between regulatory capital and liquidity creation. In particular, while we find that regulatory capital has a negative impact on bank liquidity creation, a strong culture in a bank weakens this negative association. We also find that an increase in asset-side liquidity creation is the main channel through which bank culture exerts its moderating role. Finally, our results are largely driven by smaller banks, banks with a more traditional funding structure and more profitable banks. The results of this study suggest that regulators should consider bank culture as being a crucial element in the monitoring approach when designing bank regulation and supervision.

银行资本、流动性创造和银行文化的调节作用:使用机器学习方法进行调查
本实证研究探讨了强大的银行文化是否有助于加强、削弱或不会影响监管资本与流动性创造之间的关系。利用机器学习方法和银行的 10-K 报告,我们首先衡量了 1995 年至 2019 年期间美国部分银行控股公司(BHC)的企业文化。我们发现,银行文化确实会影响监管资本与流动性创造之间的联系。特别是,虽然我们发现监管资本对银行流动性创造有负面影响,但银行的强大文化会削弱这种负面关联。我们还发现,资产端流动性创造的增加是银行文化发挥调节作用的主要渠道。最后,我们的研究结果主要是由规模较小的银行、资金结构较为传统的银行和盈利能力较强的银行得出的。本研究的结果表明,监管机构在设计银行监管和监督方法时,应将银行文化视为监督方法中的一个关键要素。

期刊介绍: The Journal of Financial Stability provides an international forum for rigorous theoretical and empirical macro and micro economic and financial analysis of the causes, management, resolution and preventions of financial crises, including banking, securities market, payments and currency crises. The primary focus is on applied research that would be useful in affecting public policy with respect to financial stability. Thus, the Journal seeks to promote interaction among researchers, policy-makers and practitioners to identify potential risks to financial stability and develop means for preventing, mitigating or managing these risks both within and across countries.
