(14)It is appropriate to implement a leverage ratio buffer requirement for institutions identified as global systemically important institutions (G-SIIs) in accordance with Directive 2013/36/EU and with the BCBSs standard on a leverage ratio buffer for global systemically important banks (G-SIBs) published in December 2017. The leverage ratio buffer was calibrated by the BCBS for the specific purpose of mitigating the comparably larger risks to financial stability posed by G-SIBs and, against that background, should only apply to G-SIIs at this stage. However, further analysis should be done to determine whether it would be appropriate to apply the leverage ratio buffer requirement to other systemically important institutions (O-SIIs), as defined in Directive 2013/36/EU, and, if that is the case, in what manner the calibration should be tailored to the specific features of those institutions.
