An Overview of Municipal Bonds Data.

Before we get into the details of how our data is created, a quick review of municipal bonds may be helpful.


Part of the fixed income asset class, municipal bonds (aka “munis”) are debt obligations issued by government entities. When investors buy munis, they are loaning money to the issuer and in return will receive a set number of interest payments over a predetermined period of time. When the bond matures, the principal amount of the loan is paid back.

Although municipal bonds come in both taxable and tax-exempt formats, tax-exempt bonds tend to be in higher demand. They give most investors a way to preserve capital while earning tax-free income.

That is, the interest investors earn on tax-free municipal bonds is exempt from federal, and in most cases, state and local income taxes.


There are two types of municipal bonds:

  • General Obligation Bonds – issued to raise immediate capital to cover expenses, and are supported by the taxing power of the issuer.
  • Revenue Bonds – issued to fund infrastructure projects, and are supported by the income generated by those projects.

Both general obligation and revenue municipal bonds are tax-exempt.


Municipal bonds are considered low-risk investments compared to other investments because of the high likelihood that their issuers will repay their debts. However, they are not risk-free.

Government entities that issue such bonds can become unable to meet their financial obligations and miss interest payments or the payment of the principal at the maturity date. There are several types of risks associated with munis:

Market Risk

Most municipal bonds pay a fixed interest rate, but the underlying prices of bonds in the secondary market do fluctuate due to market conditions. The biggest factors that influence these prices are interest rates and expectations of what will happen to interest rates.

For example, if interest rates fall, newly issued bonds will pay a lower yield than existing bonds. So the older bonds become more desirable and their prices rise.

Note that if an investor buys a bond and holds it until maturity, there is no market risk because the investor will receive the principal in full at maturity.

Call Risk

Some municipal bonds allow the issuer to repay all or a portion of the bond before its maturity date. When this happens, the investor receives his/her capital back with a premium added in exchange for the early debt retirement. When a bond is called, the income stream ends early.


One way investors can better understand the creditworthiness of an issuer is via ratings. Also, many municipal bonds are backed by insurance policies that guarantee repayment to investors should the issuer default.
