Introduction of the Renminbi Business Facility

55th Floor, Two International Finance Centre, 香 港 中 環 金 融 街 8 號 國 際 金 融 中 心 2 期 55 樓 8 Finance Street, Central, Hong Kong 網 址：www.hkma.gov.hk Website: www.hkma.gov.hk Our Ref.: G12/129/4C B1/15C 26 September 2025 The Chief Executive All Authorized Institutions Dear Sir / Madam, RMB Business Facility I am pleased to announce the introduction of the Renminbi Business Facility (RBF) in support of authorized institutions (AIs) further developing their RMB business. 2. As a stable source of RMB funds to support the industry in offering RMB trade finance services to corporates, the RMB Trade Financing Liquidity Facility (RMB TFLF) has been running smoothly since its launch in February 2025. Having considered the useful feedback from the industry regarding the implementation of the RMB TFLF, the Hong Kong Monetary Authority (HKMA) is introducing a new RBF that replaces the RMB TFLF with enhanced terms and extended scope of eligible RMB financing activities. The potential usage of the RBF by AIs participating in the facility (Participating AIs) is significantly broader than that of the RMB TFLF, hence further strengthening Hong Kong’s leading position as the global offshore RMB business hub. The RBF will be rolled out in three phases, with details set out below. RBF Phase 1 3. The HKMA will launch Phase 1 of the RBF on 9 October 2025 by introducing the following enhancements to the current RMB TFLF, applicable to AIs which have been assigned a quota under the RMB TFLF1 : 1 For the avoidance of doubt, the assigned quota and terms as stated in the facility letter for the RMB TFLF, except for the amended terms listed in this section, will continue to apply during Phase 1 of the RBF.

(i) Reduction in interest rate – The facility interest rate will be the Shanghai Interbank Offered Rate of the corresponding tenor on trade date. The existing spread of 25 basis points will no longer apply for both repo and cross-currency types of transactions; (ii) Extending eligibility to intragroup funding activities – Participating AIs can on-lend the RMB funds obtained from the RBF to their overseas intragroup banking entities to support the provision of RMB trade finance to the entities’ corporate customers. Details of the eligible RMB financing activities under the RBF can be found in Annex 1. (iii) Streamlining the tapping process – The basis of tapping the facility (i.e. portfolio basis and deal-by-deal basis) will be replaced by a minimum size of RMB10 million per tapping. For operational efficiency, Participating AIs should consolidate the funding needs of the underlying RMB activities and tap the RBF no more than once per tenor per business day; and (iv) Adding a tenor of 1 year – Tenors will be extended to include 1 year, in addition to the existing choices of 1 month, 3 months and 6 months. RBF Phase 2 4. The RBF will proceed to Phase 2 on 1 December 2025 with the following additional enhancement: (v) Broadening the scope of eligible RMB financing activities – Besides trade financing activities, the facility will be expanded to cover RMB capital expenditure (capex) and working capital term loans granted to corporate customers of Participating AIs or their overseas intragroup banking entities. Details of the eligible activities can be found in Annex 1. RBF Phase 3 5. The RBF will enter Phase 3 starting from 2 February 2026 with the following additional enhancements to support Participating AIs’ collateral management of repo transactions2 : 2 Operations for RMB/HKD cross-currency swap transactions under the RBF will remain unchanged.

(vi) Enabling collateral substitution – Collateral management of repo transactions will migrate from manual processing to a more automated solution using CMU Triparty Repo Service (the Service). Thereafter, the lifecycle management of collateral and settlement of the repo transactions, including but not limited to collateral substitution, and the selection and transfer of securities, will be automatically processed under the Service. Collateral haircut and margin maintenance will be refined in light of the change (see Annex 2). AIs participating in Phase 3 of the RBF will be required to be operationally ready by the end of January 2026 for using the Service3 . Participating AIs should start engaging with CMU as soon as practicable to plan their internal workflows and conduct drills. Quota application under Phases 2 and 3 of the RBF 6. Similar to the RMB TFLF (and hence Phase 1 of the RBF), a quota will be assigned to AIs interested in participating in Phases 2 and 3 of the RBF, which will then be able to obtain RMB funds from the HKMA to support the in-scope RMB financing activities. Interested AIs4 are invited to submit an application as outlined in Annex 3 by 31 October 2025 to the HKMA for consideration. AIs participating in the RMB TFLF should also submit an application if they wish to continue taking part in the RBF. 7. In allocating a quota to an AI applicant, the HKMA will consider: • the existing eligible RMB financing activities of the AI and its overseas intragroup banking entities; • in the case of an AI participating in RMB TFLF – its usage of the allocated quota and related operation; • the potential business pipeline as projected by the AI; and • the relevant controls and governance of the AI in satisfying themselves that the usage of the RMB funds (including those used by the AIs’ overseas intragroup banking entities) is fit for purpose and within scope. 3 Participating AIs should refer to the CMU operating procedures, including CMU Reference Manual and relevant circulars issued by the CMU from time to time. 4 Participating AIs are required to have signed with the HKMA the Master Sale and Repurchase Agreement for the provision of liquidity assistance.

8. The HKMA will inform the respective AI applicants bilaterally of the amount of the quota assigned to them and arrange the signing of a facility letter5 . Details on the use of the Service under Phase 3 will also be provided to the AIs alongside the quota allocation notification. Tapping of the RBF, monitoring and reporting of usage
9. Participating AIs can tap the RBF within the assigned quota, for one or more eligible underlying RMB financing activities in batches as needed. The AIs should make best efforts to match the funding size and duration with the in-scope RMB financing activities, and to avoid tapping funding in excess of the provision of such RMB financing. Participating AIs will be required to report retrospectively at a frequency and timeframe deemed appropriate by the HKMA its outstanding in￾scope RMB financing activities against the tapped funding. Details of the updated mode of operations and retrospective reporting can be found in Annex 4 and Annex 5 respectively.
10. Same as the arrangements under the RMB TFLF, Participating AIs are expected to designate two senior executives from the first and second lines of defence respectively for overseeing the usage of the RBF, and put in place appropriate control systems for monitoring and reporting to the HKMA any deviation from the purpose of the facility. An unreasonable excess in terms of size and/or duration, as well as any suspected inappropriate use of funds may result in additional documentation requirements and application procedures for tapping the facility further, and may also lead to a reduction in the quota assigned to the AI, or any other remedial actions as warranted. Should you have any questions regarding the above, please do not hesitate to contact the HKMA Monetary Operations Division at 2878 8104. Yours faithfully, Eddie Yue Chief Executive 5 The quota assigned for the RMB TFLF (and hence Phase 1 of the RBF), if applicable, will superseded by that assigned for Phases 2 and 3 of the RBF.
