The appropriateness of the maximum level of usage of the options allowed by a supervisor will be evaluated in the independent peer review process. The level set should be consistent with the projected size of the HQLA gap faced by banks subject to the LCR in the currency concerned, taking into account all relevant factors that may affect the size of the gap over time. The supervisor should explain how this level is derived, and justify why this is supported by the insufficiency of HQLA in the banking system. Where a relatively high level of usage of the options is allowed by the supervisor (eg over 80%), the suitability of this level will come under closer scrutiny in the independent peer review.
