(56)Similarly, upon becoming bound by the output floor, the nominal amount of an institution’s Common Equity Tier 1 capital required under the systemic risk buffer and O-SII buffer could increase even though there has not been a corresponding increase in the macroprudential or systemic risks associated with the institution. In such cases, the institution’s competent authority or designated authority should review the calibration of the systemic risk buffer rates and make sure that they remain appropriate and do not double-count the risks that are already covered by virtue of the fact that the institution is bound by the output floor. Such a review should take place with the same frequency as the review of the buffers, which is annual for the O-SII buffer and every two years for the systemic risk buffer. However, it should be possible for the institution’s competent authority or designated authority to adjust the calibration of the buffers on a more frequent basis.
