The Hong Kong dollar (HKD) is the official currency of Hong Kong, a Special Administrative Region of China. It is subdivided into 100 cents and is symbolized by "$" or "HK$" to distinguish it from other dollar-denominated currencies. The Hong Kong Monetary Authority manages the currency, which is pegged to the U.S. dollar at a rate of approximately 7.8 HKD to 1 USD. The Hong Kong dollar is widely used in Hong Kong for everyday transactions, including shopping, dining, and services. It is also a significant currency in international trade and finance, reflecting the region's status as a global financial hub.
