The yield spread between a tax-free municipal bond and a Treasury bond with the same maturity.

MOB Spread

The difference in yield between tax-exempt and taxable bonds, especially tax-free municipal bonds and taxable corporate bonds. A corporate bond yields less than its stated interest rate because of taxation, whereas a tax-exempt municipal bond does not. Thus, a municipal bond paying a lower interest rate will often net the bondholder more than a corporate bond with a slightly higher interest rate, depending upon one's tax bracket.
