</p> <p> <br /> </p> <p> 企業(yè)在從事貿(mào)易及非貿(mào)易業(yè)務(wù)的過程中，從雙方達成協(xié)議，到結(jié)清債權(quán)債務(wù)，一般需要幾個月甚至1年或更長的時間，而在此期間，若計價貨幣匯率發(fā)生變動，必將使交易雙方中的某一方蒙受損失，這便產(chǎn)生了匯率結(jié)算風險。例如，美國某企業(yè)從日本進口一批機械設(shè)備。雙方于某年3月1日簽約，約定以日元計價，貨款為l400萬日元，支付日期為同年6月1日。假定3月1日美元與日元的匯率為l美元=140日元，則美國需要支付10萬美元購買l400萬日元。 </p> <p> <br /> </p> <p> 如果到了6月1日實際付款時，日元升值，美元貶值，匯率變?yōu)閘美元=l20日元，則美國企業(yè)需要支付約11.667萬美元來購買l400萬日元，比原來多付1.667萬美元。美國企業(yè)進口成本因日元升值而相應(yīng)地增加。匯率結(jié)算風險從簽訂匯率交易合同確定以外幣計價交易金額時產(chǎn)生，一直持續(xù)到實際結(jié)算時消除。一般而言，結(jié)算風險中受險部分是確定的，無論是出口還是進口，從簽訂合同到貨物裝船及最終結(jié)算為止，所有未結(jié)算的余額即為受險部分。
