摘要 過去文獻探討干預政策影響匯率的管道主要有三個:貨幣管道、資產組合管道與訊息管道。在沖銷干預不改變貨幣基數下,無法透過貨幣管道影響匯率;而過去文獻中對於資產組合管道之實證結果非常不一致,因此,Mussa在1981提出訊息管道認為央行目前的沖銷干預政策可能隱含未來的匯率與貨幣政策進而改變市場參與者的預期而影響目前的匯率水準。

Lewis (1995)使用1985年至1990年美國公開的外匯干預日資料估計一個兩變數的VAR模型,探討干預與貨幣政策之間的關係。同時檢定現在的外匯干預是否隱含未來貨幣政策的改變以及貨幣政策的改變是否引起央行採行逆勢操作的干預政策。Lewis的研究結果顯示,此兩個假設皆成立,表示外匯干預可能預測未來貨幣政策的改變以及貨幣政策的改變也可能使央行進場干預匯率。此外,Lewis也利用衝擊反應函數估計不同貨幣政策變數的衝擊對匯率的影響,發現非借入準備 (nonborrowed reserve) 的衝擊對匯率的影響較M1顯著。

本文參考Lewis的分析架構並且使用台灣資料進行實證分析並進一步估計一個三變數的VAR模型欲探討干預與匯率之直接影響效果。結果發現訊息管道與逆勢操作政策皆存在,且干預對新台幣兌美元的影響較日圓顯著;在貨幣政策變數上,非借入準備對匯率之影響較M1顯著,此結果與Lewis相符。
