[Hong Kong's total assets of the Exchange Fund decreased by HK $44.2 billion from HK $4.0329 trillion at the end of April] the Hong Kong Monetary Authority announced that as of April 30, 2023, the total assets of the Exchange Fund were HK $4.0329 trillion, a decrease of HK $44.2 billion from the end of March 2023, of which foreign currency assets decreased by HK $39.7 billion and Hong Kong dollar assets by HK $4.5 billion. According to the HKMA, the decrease in foreign currency assets was mainly due to the sale of US dollars and withdrawal of deposits from fiscal reserves under the currency board system, which was partly offset by an increase in interest income and a revaluation of investments at market prices. The decrease in Hong Kong dollar assets was mainly due to the revaluation of Hong Kong stocks at market prices.
