Individual Bonds: Municipal

Municipal bonds are debt obligations issued by public entities that use the loans to fund public projects such as the construction of schools, hospitals, and highways.

Reasons to consider municipal bonds

  • Interest income generally federally tax exempt
  • Low level of default risk relative to other bond types

Find Bonds

All municipal bonds fall into one of two categories—general obligation or revenue bonds—based on how the interest and principal repayment will be funded. Within each category, municipal bonds can be structured a number of different ways, each with different benefits and tax treatment.

General obligation bonds (GOs)
General obligation bonds represent a promise by the issuer to levy enough taxes as necessary to make full and timely payments to investors.

Revenue bonds
Principal and interest payments for revenue bonds are secured by revenues generated by the particular project being financed. In some cases revenue bonds can be backed by sales taxes, fuel taxes, or hotel occupancy taxes.

The issuers of revenue bonds are generally:

  • Non-profit organizations (501(c)( 3)).
  • Private-sector corporations (such as hospitals).
  • Entities that provide a public service (such as power utilities, public transportation authorities).

Insured bonds
Some municipal bonds are insured by policies written by commercial insurance companies. The insurance policy is intended to provide for the insurer to pay principal and interest payments to bondholders in the event the issuer defaults. Investors should take into account the creditworthiness of both the insurer and the issuer when considering insured bonds.

Taxable municipal bonds
The interest on some municipal bonds is taxable because the federal government will not subsidize the financing of activities that do not provide significant benefit to the public. Bonds issued to finance things like stadiums, replenishment of a municipality’s underfunded pension plan, or investor-led housing are a few examples of issues that would not qualify for federal tax exemption. Build America Bonds (BABs) are a recent category of taxable municipal bonds, introduced in the wake of the 2008 financial crisis. The advantage for issuers is that they receive a 35% federal rebate on interest costs for these bonds. BABs only subsidize an issuer’s borrowing cost. There is no implied backing from the federal government.

Zero-coupon bonds
Zero-coupon municipal bonds are issued at an original issue discount, with the full value, including accrued interest, paid at maturity. Interest income may be reportable annually, even though no annual payments are made. Market prices of zero-coupon bonds tend to be more volatile than bonds that pay interest regularly.

Original-issue discount bonds
These are municipal bonds issued at a price below face value (par) which qualify for special treatment under federal tax law. The difference between the issue price and the face value is treated as tax-exempt income rather than as capital gains if the bonds are held to maturity.

Pre-refunded bonds
Pre-refunded bonds result from the advance refunding of bonds that are not currently redeemable. Once issued, the proceeds are placed in an escrow account set up to generate enough cash flow to pay interest and principal up to the first call date. The goal is typically to provide present-value savings to the issuer, but in some cases can be used to change the indenture on the bonds. The escrow account is most often funded with U.S. Treasuries (although other instruments are sometimes used), in which case the pre-refunded bonds are considered relatively safe.

Escrowed-to-maturity (ETM) bonds
Bonds are "escrowed to maturity" when the proceeds of a refunding issue are deposited in an escrow account for investment in an amount sufficient to pay the principal and interest on the issue being refunded. In some cases, though, an issuer may expressly reserve its right to exercise an early call of bonds that have been escrowed to maturity. The escrow account is most often funded with U.S. Treasuries (although other instruments are sometimes used), in which case the escrowed bonds are considered relatively safe.

Housing bonds
Housing bonds are securities backed by mortgages and mortgage loan repayments. Although not reflected as part of a traditional "call schedule," these bonds can be called at any time from the prepayment of principal on the underlying mortgages, and therefore display as callable and subject to extraordinary redemption (ER) provisions.

Municipal notes
Municipal notes are short-term debt obligations that usually mature within a year or less, but may mature within two or three years, depending on the source of the redemption. Municipalities issue notes to generate stable cash flow while they wait for other expected revenues. The types of municipal notes depend on the source of future cash flow, such as Tax Anticipation Notes (TANs), Revenue Anticipation Notes (RANs), and Bond Anticipation Notes (BANs).

Conduit bonds
These are revenue bonds issued by state agencies called “conduit issuers” that are third-party entities that act on behalf of the actual borrowers, typically private nonprofit (501(c)(3)) entities. Conduit bonds may be issued for projects such as nonprofit hospitals, housing developments, transportation hubs, student loan programs, and public works projects. The third-party, conduit borrower—not the issuing agency—is responsible for interest payments and principal repayments. The issuing agency generally is not obligated to use any other source to repay the bonds if the conduit borrower fails to make loan repayments. So, unless the official statements indicate otherwise, investors in conduit bonds should not view the issuing governmental agency as a guarantor on conduit bonds.

In general the bond market is volatile, and fixed income securities carry interest rate risk. (As interest rates rise, bond prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities.) Fixed income securities also carry inflation risk, liquidity risk, call risk, and credit and default risks for both issuers and counterparties.
