The Hong Kong dollar (Chinese: 港元, sign: HK$; code: HKD) is the official currency of Hong Kong. It is divided into 100 cents. Historically, it was also divided into 1000 mils. The Hong Kong Monetary Authority is the monetary authority of Hong Kong and the Hong Kong dollar.
Three commercial banks are licensed by the Hong Kong Monetary Authority to issue their own banknotes for general circulation in Hong Kong. These banks — HSBC, Bank of China, and Standard Chartered — issue their own designs of banknotes in denominations of HK$20, HK$50, HK$100, HK$150, HK$500, and HK$1000, with all designs being similar to one another in the same denomination of banknote. However, the HK$10 banknote and all coins are issued by the Government of Hong Kong.
