Explanation:

The dollar (or money) duration or DV01 is the dollar value per 01 (100 basis points) of a bond.  It measures a bond’s interest rate risk in nominal or dollar-amount terms.  Dollar (money) duration assumes that bonds have fixed rates with fixed interval payments.   It is a linear approximation of how a bond's value will change in response to changes in interest rates.
