Hong Kong Monetary Authority: As of the end of May, the total foreign exchange reserves of Hong Kong amounted to 4.1595 trillion Hong Kong dollars.

On June 30, the Hong Kong Monetary Authority announced today that as of May 31, 2025, the total assets of the Exchange Fund of Hong Kong amounted to HK$4,159.5 billion, an increase of HK$186.2 billion from the end of April 2025. Foreign currency assets increased by HK$208.1 billion, while Hong Kong dollar assets decreased by HK$21.9 billion. The increase in foreign currency assets was mainly due to the purchase of US dollars and investments revalued at market prices under the Currency Board System. The decrease in Hong Kong dollar assets was mainly attributed to a decrease in bank deposits, partially offset by the revaluation of Hong Kong stocks at market prices. The accounts of the Currency Board showed that the monetary base stood at HK$2,124.9 billion at the end of May 2025, an increase of HK$142.2 billion from the end of April 2025, representing a growth of 7.2%. The increase in the monetary base was primarily due to the sale of Hong Kong dollars under the Currency Board System. The total assets of the Exchange Fund increased by HK$162.8 billion to HK$2,356.2 billion at the end of May 2025, representing a growth of 7.4%. The increase in total assets was mainly attributed to the purchase of US dollars and the revaluation impact of foreign currency investments converted into Hong Kong dollars under the Currency Board System. The backing ratio increased from 110.62% at the end of April 2025 to 110.88% at the end of May 2025.
