An official at HKMA's New York Representative Office confirmed the transaction, the first such intervention since 2020, by phone.
Hong Kong intervened to defend its peg, buying a record amount of US dollars after the city's currency rose to the upper end of its trading band.
The Hong Kong Monetary Authority spent HK$46,539 million (US$6 billion or $7.79 billion) on the US currency, its highest-ever purchase of the dollar in one day, according to data compiled by Bloomberg that dates back to 2004.
