Answer:
the current yield on the bond is lower now than when the bond was originally issued.
Explanation:
A bond can be defined as a debt or fixed investment security, in which a bondholder (investor or creditor) loans an amount of money to the bond issuer (government or corporations) for a specific period of time. The bond issuer are expected to return the principal (face value) at maturity with an agreed upon interest (coupon), which are paid at fixed intervals. 
A yield to maturity can be defined as the bond's total rate of return required by the secondary market while the coupon rate is defined as the annual interest of a bond divided by its face value.
Hence, if the coupon rate on a bond is higher than the yield to maturity, the current yield on the bond is lower now than when the bond was originally issued.
