Basel III leverage ratio framework and disclosure requirements
Basel III's leverage ratio is defined as the "capital measure" (the numerator) divided by the "exposure measure" (the denominator) and is expressed as a percentage. The capital measure is currently defined as Tier 1 capital and the minimum leverage ratio is 3%. The Committee will continue to monitor banks' leverage ratio data on a semiannual basis in order to assess whether the design and calibration of a minimum Tier 1 leverage ratio of 3% is appropriate over a full credit cycle and for different types of business models. It will also continue to collect data to track the impact of using either Common Equity Tier 1 (CET1) or total regulatory capital as the capital measure.
