摘要

基于非线性结构的银行业模型，我们发现银行资本要求的变化对贷款的影响具有很强的状态依赖性。当银行盈利或保持自愿资本缓冲时，对贷款的影响通过 "定价渠道 "产生，影响很小：资本要求提高 1 个百分点，贷款减少 0.1%。当银行受到资本约束时，对贷款的影响通过 "数量渠道 "产生，这种影响很大：资本要求降低 1 个百分点，贷款就会增加 10%。我们的研究结果为在 "正常 "宏观金融环境下建立积极中性的反周期资本缓冲提供了理论依据。

The state-dependent impact of changes in bank capital requirements

Based on a non-linear structural banking sector model, we show that the impact of changes in bank capital requirements on lending is strongly state-dependent. When banks make profits or maintain voluntary capital buffers, the impact on lending works through a “pricing channel” which is small: 0.1% less loans for a 1pp capital requirement increase. When banks are capital-constrained, the impact on lending works through a “quantity channel” which is large: 10% more loans for a 1pp capital requirement reduction. Our results provide a theoretical justification for building up a positive neutral countercyclical capital buffer in “normal” macro-financial environments.
