Investors in municipal bonds purchase and/or trade the securities.
Example:
An issuer sells a $50 million tax-exempt bond issuance which has maturities from year 2 through year 30. Bond funds might be interested in the longer bonds because the longer the bond, the more price volatility, and the more potential gain should markets move and they sell the securities. Money market funds might be interested in the shorter maturities because they better fit their clients’ goals.
Individuals and insurance companies might be interested in the middle year maturities because they offer tax-exempt earnings and less volatility than the longer bonds and are therefore a safer investment.
There are several reasons why investors purchase municipal bonds. For individuals, municipal bonds are commonly purchased for their tax-exempt income. Others purchase municipal bonds for their future trading value. Banks might purchase municipal bonds of local issuers to show their interest in the community. Insurance companies might buy municipal bonds for both the tax-exempt income and the reduced credit risk versus a corporate bond.
