Global systemically important banks: Assessment methodology and the additional loss absorbency requirement

Updated 12 January 2016

The Basel Committee's assessment methodology for global systemically important banks requires a sample of banks to report a set of indicators to national supervisory authorities. These indicators are then aggregated and used to calculate the scores of banks in the sample. Banks above a cut-off score are identified as G-SIBs and are allocated to buckets that will be used to determine their higher loss absorbency requirement.

This page provides various information that the Basel Committee uses in this process.
