何謂沽外幣

外幣除了 "買", 好像還能 "沽", 請問其原理是 you are bearish on that currency: we are expecting that currency will depreciate in future. 沒有貨 (外幣), 但可以沽, 是否叫 "借貨沽空"? Yes, we will need to pay interest on that currency. 那借貨後, 有限定多久後要還嗎? 可否跟買外幣一樣, 長渣"沽空"了的貨? Yes, as long as you can pay the interest and is not being CALL MARGIN, you can hold a long period of time without limit.

那麼利息約是多少? 每間銀行都不同嗎? 每種貨幣都不同嗎?
