The Hong Kong Monetary Authority (HKMA) announced today (31 October) that the total assets of the Exchange Fund amounted to HK$4,152.2 billion as at 30 September 2025, HK$82.0 billion higher than that at the end of August 2025. Hong Kong dollar assets increased by HK$97.2 billion while foreign currency assets decreased by HK$15.2 billion.
The rise in Hong Kong dollar assets was mainly due to the increase in Exchange Fund Bills and Notes issued but not yet settled at month end and mark-to-market revaluation of Hong Kong equities. The decline in foreign currency assets was mainly due to withdrawals of Fiscal Reserves placements and reduction in the month-end balances of unsettled purchase of securities, which were partly offset by interest income from investments and mark-to-market revaluation of investments.
The Currency Board Account shows that the Monetary Base at the end of September 2025 was HK$2,020.2 billion, increased by HK$6.0 billion, or 0.3%, from the end of August 2025. The increase was mainly due to the increase in the outstanding amount of Certificates of Indebtedness and the amortisation of discount on Exchange Fund Bills and Notes issued.
The amount of Backing Assets increased by HK$7.0 billion, or 0.3%, to HK$2,218.2 billion at the end of September 2025. The increase was mainly attributable to interest income from investments. The Backing Ratio increased from 109.78% at the end of August 2025 to 109.80% at the end of September 2025.
