Cyclicality of liquidity creation: Nonlinear evidence from US bank holding companies
利用美国银行控股公司1993-2020年季度数据，发现商业周期对流动性创造有显著非线性影响，扩张期流动性创造多于衰退期，为银行和央行提供政策参考。
Abstract Using a panel smooth transition regression framework on a new proxy of the business cycle (BC) index and quarterly data of US bank holding companies from 1993Q1 to 2020Q1, our results provide empirical support for the theory that the BC has a nonlinear effect on liquidity creation. We find a positive and highly significant nonlinear effect of the BC on liquidity creation, which not only supports the pro‐cyclicality of liquidity creation but also improves the liquidity creation estimation compared to previous studies. The results are robust to different proxies of the BC and model specifications. We also document that US bank holding companies create liquidity more during the expansion phase (normal times) than during the recession phase (crisis times) of the BC, suggesting an asymmetrical effect of BC changes on liquidity creation. Our findings have important implications for financial market participants by suggesting that banks should keep alternative sources of funding on hand during the BC recession phase. Insights from our study also provide policy implications for central banks and prudent supervisors to consider when incentivizing banks, for instance, by lowering regulatory requirements, adjusting the policy rate, or implementing any other quantitative easing policy during the BC recession phase to keep the financial system efficient.
