What factors affects Hong Kong's exchange rate?

匯率其實係要睇一個國家對另外一個國家貨幣的需求同供應
如果好多人想要果種貨幣, 需求會上升, 於是匯率就會上升啦~

好多因素決定一個國家的匯率:

如果佢的出口多於入口, 即係好多外國人都想買你國家做的貨,對國家貨幣需求會上升, 匯率就會上升。

呢個當中又有好多因素, 好似一個國家的貨品係唔係好咁.

國家的通漲同經濟的增長‧高增長通漲會導致貨幣眨值

因為同一件貨品會o向人地國家賣得平 d, 根據 the law of one price, o的人會去第二個國家買野返黎o向自己個國家賣。要買人地的野就要人地的貨幣, 亦都會令到自己國家的貨幣供應少左, 所以自己的貨幣會眨值。

國家政治的穩定

針對你的問題, 香港用 pegged exchange rate, 所以答案會再多一些。
第一就係 hkma(金管局) 的 policy

因為我地的 echange rate 佢地 set 的,
如果佢地要轉, 好明顯會影響到我地~
第二就係 美國的經濟
美國的通漲同利率o向 pegged exchange rate 之下會令到 hk 有同樣的變化, 即係如果美國通漲高, hk 都會通漲高, 會產生上面同樣的影響~
第三就係 美國的經濟政策
可以決定美國的興衰, 亦即係香港的 pegged exchange rate~




希望針對你問題果 part 可以更加幫到你啦~

1) USD exchange rate with other countries
2) US real Interest rate (risk free rate)
3) US expected inflation rate

There are several major factors that affect a currency exchange rate:
In terms of national accounting:
1. Import and export of goods and services
2. Profits and interest gained income nationally
3. Current transfer growth
4. Capital transfer growth
5. Capital inflow due to direct and portfolio investment

The factors listed above alter the supply and demand of Hong Kong dollars in the market hence the exchange rate will increase/decrease. As HKD is pegged, Hong Kong Monetary Authority (金管局) will sell and buy currencies reserve (theoretically unlimited quantity) to maintain the exchange rate at the determined level, which is 7.8HKD to 1USD.

In conclusion, the external factors affect HKD exchange rate but HKMA will take actions to maintain the pegged mechanism.

No way. Cuz HK Dlr is pegged with US dlr.
