In the bond market, the smallest measure used for quoting yields is a basis point. Each percentage point of yield in bonds equals 100 basis points. Basis points also are used for interest rates. An interest rate of 5% is 50 basis points higher than an interest rate of 4.5%. Sometimes referred to as BPS, BIPS, and pronounced "Bips"
