There are many reasons for the rise of Hong Kong dollar exchange rate, some of which include:
Increased demand for Hong Kong dollars: As Hong Kong is an international financial center, the demand for Hong Kong dollars is high. When investors' demand for Hong Kong dollars increases, the exchange rate of Hong Kong dollars will rise.
Volatility of the US dollar exchange rate: The Hong Kong dollar is pegged to the US dollar, but the exchange rate fluctuations of the US dollar will also affect the Hong Kong dollar exchange rate. When the US dollar exchange rate falls, the Hong Kong dollar exchange rate rises relatively.
Economic growth: Hong Kong's economic growth will also affect the Hong Kong dollar exchange rate. When Hong Kong's economic growth is strong, investors' demand for Hong Kong dollars increases, thus pushing up the Hong Kong dollar exchange rate.
Political factors: Political factors may also affect the Hong Kong dollar exchange rate. For example, when the political situation in Hong Kong is unstable, investors may flee from Hong Kong, leading to a decline in the Hong Kong dollar exchange rate.
In short, there are many reasons for the rise of Hong Kong dollar exchange rate, including increased demand, US dollar exchange rate fluctuations, economic growth and political factors. These factors interact and jointly determine the trend of the Hong Kong dollar exchange rate.
