The paper describes the mechanism of overlapping leverage ratio requirement and macroprudential capital buffers and associated implications for the resilience of the banking sector. It examines to what extent capital buffers can be usable to absorb losses in the case of the Czech banking sector and what impact this may have on the lending capacity of the real economy. The non-usability portion of capital buffers in the Czech banking sector amounts to CZK 27 billion (i.e. 24% of the combined capital buffer). The lending potential of the capital buffer decreases by CZK 630 billion to CZK 1.6 trillion due to overlaps under otherwise equal conditions. The results indicate that the leverage ratio requirement may prevent the capital buffers from being fully effective and can reduce created macroprudential space.

资本监管复杂性的新时代

本文描述了杠杆率要求和宏观审慎资本缓冲重叠的机制以及对银行业弹性的相关影响。它研究了资本缓冲在多大程度上可以用来吸收捷克银行业的损失，以及这可能对实体经济的贷款能力产生什么影响。捷克银行业资本缓冲的不可使用部分达 270 亿捷克克朗（即占合并资本缓冲的 24%）。由于其他条件相同的重叠，资本缓冲的贷款潜力减少了 6300 亿捷克克朗，降至 1.6 万亿捷克克朗。结果表明，杠杆率要求可能会阻碍资本缓冲充分发挥作用，并会减少创造的宏观审慎空间。
