ADDITION ONLY
「即是如果兩者的匯率偏離1元美金換7.8港元的水平的話,發鈔銀行便會印鈔或燒毀鈔票,令匯率回到聯繫匯率的水平」
I 'm not sure that 發鈔銀行會印鈔或燒毀鈔票, my addition as follows
e.g.If the market rate:HK$7.8=US$1,banks will buy US$1 with HK$7
in the market and then sell to the Exchange Fund for HK$7.8
When banks buys US$ in the market, the demand for US$ will rise
and the price ofUS$wii rise back to US$1=HK$7.8
e.g.If the market rate:HK$9=US$1,banks will buy US$ with HK$7.8
from the Exchange Fund and then sell US$1 for HK$9 in the market
When banks sells US$ in the market, the supply of US$ will rise
and the price of US$ will fall back to US$1=HK$7.8
