The Hong Kong Monetary Authority (HKMA) announced today (30 September) that the total assets of the Exchange Fund amounted to HK$4,070.2 billion as at 31 August 2025, HK$32.4 billion lower than that at the end of July 2025. Foreign currency assets decreased by HK$36.1 billion while Hong Kong dollar assets increased by HK$3.7 billion.
The decline in foreign currency assets was mainly due to the sale of US dollars under the Currency Board arrangements. The rise in Hong Kong dollar assets was mainly due to mark-to-market revaluation of Hong Kong equities.
The Currency Board Account shows that the Monetary Base at the end of August 2025 was HK$2,014.2 billion, decreased by HK$28.4 billion, or 1.4%, from the end of July 2025. The decline was mainly due to the purchase of HK dollars under the Currency Board arrangements, which was partly offset by increase in the outstanding amount of Certificates of Indebtedness.
The amount of Backing Assets decreased by HK$80.3 billion, or 3.5%, to HK$2,211.2 billion at the end of August 2025. The decrease was mainly attributable to the transfer of assets out of the Backing Portfolio to the Investment Portfolio in accordance with the arrangement approved by the Exchange Fund Advisory Committee, and the sale of US dollars under the Currency Board arrangements. The Backing Ratio decreased from 112.19% at the end of July 2025 to 109.78% at the end of August 2025.
