We explore and summarize the evolution in bank capital regulations and bank risk after the global financial crisis. Using a new survey of bank regulation and supervision covering more than 120 economies, we show that regulatory capital increased, but some elements of capital regulations became laxer. Analyzing bank-level data, we also document the importance of defining bank regulatory capital narrowly as the quality of capital matters in reducing bank risk. This is particularly true for banks that have more discretion in the computation of regulatory capital ratios and are subject to weaker market monitoring.

全球金融危机后的银行资本监管和风险

我们探索并总结了全球金融危机之后银行资本法规和银行风险的演变。通过对涵盖120多个经济体的银行监管进行的新调查，我们发现监管资本有所增加，但是资本监管的某些要素却变得更为宽松。分析银行级别的数据，我们还记录了狭窄定义银行监管资本的重要性，因为资本质量对降低银行风险具有重要意义。对于在监管资本比率的计算上具有更大的自由度并且受到较弱的市场监控的银行而言，尤其如此。
