Three major banks issue notes of Hong Kong –Hong Kong and Shanghai Banking Corporation (HSBC), Standard Chartered Bank and Bank of China. The appearance of paper currency may differ depending on which bank issued the notes. The local currency of Hong Kong is the Hong Kong dollar, with denominations of $1000, $500, $100, $50, $20 and $10 in bills and $10, $5, $2, $1, $0.5, $0.2 and $0.1 in coins. Major banks are open 9am-4:30pm on weekdays and 9am-12:30pm on Saturdays. The current exchange rate for HK$ to US$ is HK$7.80 to US$1.
Foreign currency exchange centers, as well as ATMs, can be found anywhere in Hong Kong. It is best not to sell your foreign currency in the Hong Kong International Airport as the exchange rates there for HK$ to other currencies are lower. When getting cash from ATMs, be reminded of the international fees that are being charged to you per withdrawal.
