債券等價收益率(Bond Equivalent Yield,BEY)
The bond equivalent yield or BEY for an investment is a calculated annual percentage yield for an investment, which may not pay out yearly. It is not to be confused with a bond's coupon rate. This allows investments which payout with different frequencies to be compared.
為方便與債券的收益率直接比較,將貨幣市場金融產品如國庫券的收益率轉換為年收益率 (annual yield),這種收益率則稱為債券等價收益率。短期國債的債券等價收益率,具體表述如下:
BEY=(利息額/折價)×(365/到期天數)
像美國的國庫券因期限在一年以內,到期前不付息,價格因而以低于面值的貼現方式表達,如果不經轉換計算,其收益水平便無法直接與較長期的公債相比較。
債券等價收益率的例子
投資者可能支付9852元購買面額為10000為期91天的短期國債。到期時,投資者將收到10000元的款項,利息總額為148元。短期國債沒有票面利率,則債券等價收益率為:
(148÷9852)×(365÷91)=6.025%
