This paper uses Call Report data to examine the impact of home country monetary policy on foreign bank subsidiary lending in the United States during the COVID-19 pandemic. Examining a large sample of foreign bank subsidiaries and domestic U.S. banks, we find that foreign bank lending growth was positively associated with both lower home country policy rates and negative home country rates. Point estimates indicate that a one standard deviation decrease in home country policy rates was associated with a 3.5 percentage point increase in lending growth, while negative home country policy rates added an additional 3.0 percentage points on average. Disparities in sensitivity to home country rates also exist by bank size, as large banks exhibited more responsiveness to home country policy rate levels, but were less responsive to negative policy rates. Easier home country policy rates are also found to impact negatively on growth in capital ratios and bank income, in keeping with expanded foreign subsidiary activity. However, income responses to negative home country rates are mixed, in a manner suggesting balance sheet adjustment to changes in relative home and host country conditions. Overall, our findings confirm that the bank lending channel for global monetary policy spillovers was active during the pandemic crisis.
本文利用银行监管报告数据,研究了在新冠疫情期间母国货币政策对美国外资银行子公司放贷的影响。通过考察大量外资银行子公司和美国本土银行样本,我们发现外资银行贷款增长与母国较低的政策利率及负政策利率均呈正相关。点估计表明,母国政策利率下降一个标准差,贷款增长会增加3.5个百分点,而负政策利率平均会额外增加3.0个百分点。银行规模不同,对母国利率的敏感度也存在差异,大型银行对母国政策利率水平反应更灵敏,但对负政策利率反应较弱。研究还发现,母国宽松的政策利率对资本充足率和银行收入增长有负面影响,这与外资子公司业务扩张相符。然而,银行收入对母国负政策利率的反应不一,这表明银行资产负债表会根据母国和东道国相对状况的变化进行调整。总体而言,我们的研究结果证实,在疫情危机期间,全球货币政策溢出效应的银行贷款渠道是活跃的。
