Understanding the Hong Kong Dollar (HKD) Exchange Rate
The Hong Kong Dollar (HKD) is unique because of the Linked Exchange Rate System (LERS). Since 1983, the HKD has been pegged to the United States Dollar (USD). The Hong Kong Monetary Authority (HKMA) maintains the exchange rate within a narrow protected band of 7.75 to 7.85 HKD per 1 USD.

Capital Flows: Large IPOs or stock market activity in the Hong Kong Stock Exchange (HKEX).
Global Economic Health: As a major financial hub, Hong Kong's currency is sensitive to international trade trends.
