the pound, euro and Australian dollar?
the main currencies such as the pound,the euro and Australian dollar have collapsed seriously because of the eruption of recent worldwide financial crisis. As can be seen obviously,these currencies are being devaluated sharply.Will they be forever depressed or recover from that financial crisis in forthcoming months?
thanks for answering
this is the question that i brought forward , not translation material

No,they won't.The value of a currency is controlled by many elements such as GDP,government,banks and the buyers and sellers(market reason).We can assume that the world's finance is a human,will he die just because of hasn't have one meal?Of course no.The market will control it to make the whole finance balance.
