何解香港要跟美國減息?

美國減息香港銀行要跟住減係因為香港有
另外吾減得吾得?依個問題就只能夠講
香港有跟不過最近依次跟少左架喇
至於有咩壞影響方面
我諗我解釋下聯繫匯率制度之後你再自己諗下
真係吾明先再問我啦

香港o既經濟體系對外高度開放，靈活性強，聯繫匯率提供一個穩定、明確同清楚o既貨幣制度，十分適合香港作為國際金融中心地位。聯繫匯率有助香港經濟應付外圍震盪，以免因貨幣價格突然下瀉而受損或波動。聯繫匯率為香港建立穩固的貨幣基礎，除發揮其他作用外，還可減低進口商、出口商及國際投資者須面對的外匯風險。
以下是解題重點:
聯繫匯率的弊處是，即使香港的經濟周期未必與美國的周期一致，香港仍須跟隨美國的貨幣政策，此外，香港亦不能利用名義匯率的變動作為調整機制。對於外圍因素轉變，香港須透過實質經濟活動的通脹或通縮作出調整。不過，聯繫匯率仍是利多於弊

真係仲吾明可以去我個板度留言
我一定會覆

The simple reason is HK$ is pegged to US$.
If the interest rate in US is lower then interest rate in Hong Kong. People will then sell US$ and buy HK$ with a higher interest return. The monetary authority has to 'sell' out HK$ and to 'buy' in US$ in order to maintain the exchange of HK$ 7.8 to US$1. This create a very high pressure to Government to get in more US$ with low return.
To balance this impact, the interest rate in HK$ will make a synchronizing decrease to the interest rate in US so as to maintain an equilibrium of the demand and supply of HK$ and to avoid the fluctuation of the exchange rate between US$ and HK$, a great impact to business activities and thus the economy in Hong Kong.
