你好。我最近老师也在说这个问题,我们讨论一下吧。(我也是一知半解,说的不好请见谅)
影响FX的几个因素:
1.relative inflation rate: the country with the higher inflation rate will tend to see its currency devalue relative to other countries with lower inflation rates.(purchasing power parity)
2. relative real interest rate: countries with higher interest rate might attract more capital and have a stronger exchange rate.
3. relative economic growth rate: higher economic growth rate, more capital
4. demand for a country's goods and services and financial assets: higher demand , greater currency
5. government policy: restriction on foreign exchange , trade and investment can depress a currency's value.
6. rapid productivity growth: higher productivity growth, greater currency.
7. current account: 1) large current account deficit can foreshadow currency problems, since it implies a large amount of foreign capital is needed to finance current spending levels.(我自己很不确定这是应该造成贬值还是升值,按理说的话,外资注入,似乎是会让它增值。。。

) 2)trade deficit: indicates the currency is overvalued and needs to fall.
主要就是这几个原因吧,还有一些关于risk的因素也会使得exchange rate变化。。
对于你说的这个问题,我认为是的,ZF抛售会让汇率下降。
此外,我想请问你,forward FX transaction 的意义何在啊?我不懂这个了,,我觉得和期货差不多,求科普。。O(∩_∩)O谢谢
