The call option is a prevalent feature of both corporate bonds and tax-exempt (muni) bonds. Virtually every muni is callable at par after 10 years. Issuers compensate the investors for the call option by paying a higher coupon or by accepting a lower price, relative to a like optionless bond.

Asymmetrical tax treatment is typical. Corporations deduct the interest paid on their bonds, which are usually held in non-taxable accounts. Municipalities don’t pay tax, while muni investors are always taxable.

Suppose the market is indifferent between fairly priced callable and non-callable bonds. From the perspective of the issuer, due to the above-mentioned tax asymmetry, one of these bonds may be preferable. It turns out that the call option is desirable for corporate bonds, because the expected savings from refinancing exceed the cost of the option. But in the case of munis, the cost of the option exceeds the expected savings; optionless muni bonds would be preferable to callables.
