63. The usage of any of the above options would be constrained by a limit specified by supervisors in jurisdictions whose currency is eligible for the alternative treatment. The limit should be expressed in terms of the maximum amount of HQLA associated with the use of the options (whether individually or in combination) that a bank is allowed to include in its LCR, as a percentage of the total amount of HQLA the bank is required to hold in the currency concerned.³¹ HQLA associated with the options refer to: (i) in the case of Option 1, the amount of committed liquidity facilities granted by the relevant central bank; (ii) in the case of Option 2, the amount of foreign currency HQLA used to cover the shortfall of HQLA in the domestic currency; and (iii) in the case of Option 3, the amount of Level 2 assets held (including those within the 40% cap).

64. If, for example, the maximum level of usage of the options is set at 80%, it means that a bank adopting the options, either individually or in combination, would only be allowed to include HQLA associated with the options (after applying any relevant haircut) up to 80% of the required amount of HQLA in the relevant currency.³² Thus, at least 20% of the HQLA requirement will have to be met by Level 1 assets in the relevant currency. The maximum usage of the options is of course further constrained by the bank’s actual shortfall of HQLA in the currency concerned.

65. 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.

³¹ The required amount of HQLA in the domestic currency includes any regulatory buffer (ie above the 100% LCR standard) that the supervisor may reasonably impose on the bank concerned based on its liquidity risk profile.
³² As an example, if a bank has used Option 1 and Option 3 to the extent that it has been granted an Option 1 facility of 10%, and held Level 2 assets of 55% after haircut (both in terms of the required amount of HQLA in the domestic currency), the HQLA associated with the use of these two options amount to 65% (ie 10%+55%), which is still within the 80% level. The total amount of alternative HQLA used is 25% (ie 10% + 15% (additional Level 2A assets used)).
