A currency's strength is determined by the interaction of a variety of local and international factors such as the demand and supply in the foreign exchange markets; the interest rates of the central bank; the inflation and growth in the domestic economy; and the country's balance of trade.

一種貨幣的強弱取決於各種本地和國際因素的相互作用，例如外匯市場的供求關係；中央銀行的利率；國內經濟的通貨膨脹和增長；以及該國的貿易平衡。
