Additional "capital buffers", such as the countercyclical capital buffer, were introduced after the 2008/09 crisis. These buffers were requested in addition to banks' minimum capital requirements. They should be built up during good times and can be used during bad times. While buffer requirements were reduced quickly in the spring of 2020, financial institutions have been reluctant to use the additional leeway as they may fear market stigma effects if capital ratios fall and they might abstain from new loans due to high uncertainty. The article argues in favor of a more simple and transparent organisation of macroprudential regulation as measures to raise the effectiveness of capital buffers, especially during a downturn.
2008/09年危机之后引入了额外的“资本缓冲”,如逆周期资本缓冲。这些缓冲要求是在银行最低资本要求之外提出的。它们应在经济形势良好时积累,并可在经济形势不佳时使用。虽然2020年春季迅速降低了缓冲要求,但金融机构一直不愿使用这一额外的回旋余地,因为它们可能担心资本比率下降会产生市场污名效应,而且由于不确定性高,它们可能会放弃发放新贷款。本文主张对宏观审慎监管进行更简单、透明的组织安排,以此作为提高资本缓冲有效性的措施,尤其是在经济低迷时期。
