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, Enhancement of the Renminbi (RMB) Liquidity Facility The Hong Kong Monetary Authority (HKMA) will introduce the following enhancement to the RMB Liquidity Facility with effect from 9 October 2025:

1. Reallocation of the intraday and overnight funds – The intraday and overnight funds, currently each for RMB 20 billion, will be changed to RMB 30 billion and RMB 10 billion respectively. The aim is to allocate resources to better meet the need of intraday funding for the increasing RMB settlement volume as cross-border RMB payments and offshore RMB activities continue to grow in Hong Kong. The total size of RMB 40 billion remains unchanged. Separately, the Primary Liquidity Providers scheme with a total of RMB 20 billion will also remain unaffected.
2. Introduction of two-week and one-month repo for T+1 settlement – In addition to providing funds of one day and 1-week tenors on T+1 basis, the existing facility will be expanded to also provide funds of two-week and one￾month via repo transactions. The interest rate will reference the prevailing market interest rates. As RMB business and activities continue to flourish, RMB funding demand increases. The facility serves as a backstop of

liquidity for banks, and the extended tenors allow more flexibility for banks in managing their funding. The updated terms and conditions for the RMB Liquidity Facility are set out in the Annex. Should you have any questions on the above, please contact the HKMA at 2878 8104. Yours faithfully, Daryl Ho Executive Director (Monetary Management) Encl.
