Floater duration
Near-zero sensitivity of price to the level of rates: the coupon is reset in line with the base, so the bond is under no obligation to cheapen when rates rise.
How to read the number
The whole interest rate risk of such a bond is the distance to the next reset date. Everything else in its price is about credit.
When the metric lies
Zero interest rate duration is not zero risk. A floater's price follows the credit spread and demand for the instrument, and in stressed periods floaters cheapen along with everything else.
