G-SIB assessment reporting instructions

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.

Set out below are the reporting instructions and reporting templates used to collect data from banks, as well as the year-end and average exchange rates to be used in the calculation of indicator amounts.
