The Hong Kong Dollar (HKD) is the official currency of Hong Kong and is used as a medium of exchange in the financial markets. It is a popular currency for investors, as it is subject to fewer fluctuations than other currencies. The HKD is also used as a hedge against currency risk, as it is relatively stable even in times of global economic uncertainty. As an international currency, the HKD is widely accepted by financial institutions, enabling investors to easily access global markets and take advantage of potentially lucrative opportunities. The HKD is also an important currency for businesses operating in Hong Kong, as it helps to facilitate trade and investment.
