Basel Standards – Leverage ratio treatment of client cleared derivatives and Revisions to leverage ratio disclosure requirements

Banking Policy Department Our Ref: B1/15C B9/143C B9/151C 12 July 2019 The Chief Executive All locally incorporated authorized institutions Dear Sir/Madam, Basel Standards – Leverage ratio treatment of client cleared derivatives and Revisions to leverage ratio disclosure requirements As you may be aware, the Basel Committee on Banking Supervision (“BCBS”) issued two documents, respectively Leverage ratio treatment of client cleared derivatives1 (“Revised LR Treatment”) and Revisions to leverage ratio disclosure requirements2 (“Revised LR Disclosure Requirements”), on 26 June 2019. The Revised LR Treatment sets out a targeted and limited revision of the leverage ratio measurement of client cleared derivatives to align it with the standardised approach to measuring counterparty credit risk exposures (SA-CCR). This followed a review conducted by the BCBS regarding the impact of the leverage ratio on banks’ provision of client clearing services. The new treatment allows both cash and non-cash forms of segregated initial margin and cash and non-cash variation margin received from a client to offset the replacement cost and potential future exposure for client cleared derivatives only. The revision balances the robustness of the leverage ratio as a non-risk-based safeguard against unsustainable sources of leverage with the policy objective set by the G20 Leaders to promote central clearing of the standardised derivative contracts. The Revised LR Disclosure Requirements specify additional requirements for banks to disclose their leverage ratios based on quarter-end and on daily average values of securities financing transactions. A comparison of the two sets of values will allow market participants to better assess banks’ actual leverage throughout the reporting period. This goes towards addressing the concerns expressed in a newsletter published last year by the BCBS regarding potential “window-dressing” by banks, whereby temporary reductions of transaction volumes around reference dates has the effect of artificially elevating leverage ratios reported or disclosed. 1 Please see https://www.bis.org/bcbs/publ/d467.pdf 2 Please see https://www.bis.org/bcbs/publ/d468.pdf

2 Both the Revised LR Treatment and the Revised LR Disclosure Requirements will come into effect on 1 January 2022. The HKMA intends to implement them having regard to the BCBS timetable and will consult the industry on its implementation proposals in due course. In the meantime, AIs are strongly recommended to familiarise themselves with the new requirements and prepare for any system changes that may be necessary for their implementation in Hong Kong.
