Types of Bonds

Request More Information

In order to distinguish one type of bond from another, you must first know who is selling you
the debt.

A bond will fall into one of four categories: those sold by the U.S. government and government agencies; those sold by corporations; those sold by state and local governments; and those sold by foreign governments.

Each category varies by yield, risk and maturity, among other characteristics. And each category carries under it several types of bond options.

In general, there are seven types of bonds: treasuries, government agencies, mortgage-backed securities, municipal bonds, zero coupon bonds, investment grade corporates and high yield bonds.

Treasuries

Treasuries are secured by the US government and are therefore considered the safest type of securities. In addition to being easy to buy and sell, they also offer several maturities from less than a year to up to 30 years. The downside of Treasuries: low yields. Characteristics include:

  • Highly liquid -- if you decide to sell before the maturity date, the secondary market is one of the largest in the world
  • Large selection of maturities
  • Safest type of bond -- secured by a direct obligation from the government
  • Predictable -- usually can obtain a favorable interest rate for the life of the security
  • Most tradable -- easy to buy and sell
  • Exempt from state and local taxes
  • Non-callable -- cannot be redeemed for payment before the maturity date

The Treasury offers three types of securities:

  • US Treasury bills -- non-interest-bearing, discounted securities with an original maturity of one year or less. Interest is received at maturity and is equal to the difference between the face value received and the purchase price.
  • US Treasury notes -- intermediate securities with maturities ranging from one to 10 years. Marketable securities that pay interest semiannually.
  • US Treasury bonds -- long-term bonds with maturities ranging from 10 to 30 years. Marketable securities that pay interest semiannually.

Government Agencies or Government Sponsored Enterprises (GSE)

Formerly called agencies, government sponsored enterprises (GSE) offer a higher yield than most Treasuries. Although very safe, they are not backed by the US to the same degree as Treasuries. They are issued by major federally sponsored agencies and the government is considered morally obligated to cover their obligation in case of a default. They are not quite as liquid and salable as Treasuries, thus the reason for their higher yield. Characteristics include:

  • Large selection of maturities
  • High-quality bonds
  • Low risk
  • Very liquid
  • Low yields, but higher than Treasuries

Mortgage-Backed Securities

Mortgage-backed securities are securities backed by a pool of mortgages, such as those issued by Ginnie Mae and Freddie Mac. Many mutual funds offer these big-ticket securities that are most popular among big institutions, such as insurance companies, pension plans and banks. However, their high yield, creditworthiness and diversity of available securities have made them increasingly popular among individual investors.

They are considered a secure investment because issuers of mortgage securities are selective in choosing the mortgages which make up their pools. In addition, securities issued by Ginnie Mae, Fannie Mae and Freddie Mac carry added guarantees that affect timely payment of principal and interest and, in some cases, full repayment even if the mortgages in the pool default. Characteristics include:

  • Safe -- payments are backed by large pools of insured mortgages
  • Large minimum purchases
  • Yields above Treasuries, but below other types of bonds
  • Diverse securities
  • Active secondary market for mortgage pass-throughs
  • Opportunity for profit and loss greater than Treasuries
  • Interest rates have additional impact in the form of mortgage prepayment speed
  • Call and extension risks
  • Available securities range from $1,000 to $25,000
  • Taxed on a current basis with respect to both the interest payments on the securities and accrued original issue discount

Municipal Bonds

Municipal bonds are debt securities issued by state and local governments, their agencies and enterprises with a public purpose. These groups include authorities for housing, toll roads and school districts, hospitals and universities.

Considered a good investment for those in a higher income tax bracket, the interest income generated from a municipal bond is exempt from federal income taxes -- though the Alternative Minimum Tax (AMT) may apply. If the investor lives in the state and county that issued the bond, the interest income may also be exempt from state and local taxes, making the bond triple tax exempt. Characteristics include:

  • Many exempt from federal, state and local taxes
  • Most are very safe -- many have their principal and interest payments guaranteed by an insurance company for a timely payment
  • Low yields, but returns higher after-tax exemptions
  • Many maturities available
  • Large secondary market, but may be hard to buy and sell

Zero Coupon Bonds

Zero coupon bonds pay no periodic interest. Rather, the interest accrues and is paid in a lump sum at maturity when the bond is redeemed at its face value. Income from a zero-coupon bond comes from the bond appreciating in value over time. Its predictability makes the bond a valuable planning and investment tool.

Most zeros are issued at a considerable discount from their face value. You can purchase government-backed zeroes, corporate zeroes as well as zero-coupon certificates of deposit (CDs). Characteristics include:

  • Returns can be bigger than for regular bonds from the same issuer
  • No interest payments
  • Buy at deep discount
  • Prices can be very volatile -- price highly dependent on interest rates
  • Tax has to be paid on imputed interest payments, except in the case of a municipal zero coupon bond
  • Predictability -- you know exactly how much you will receive when the bond mature

Investment Grade Corporates

Investment grade corporates are are debt obligations issued by private and public corporations.

Issuers represent various industry sectors including public utilities, transportation companies, industrial corporations, financial service companies and conglomerates. Companies use bonds to raise funds for a variety of purposes, from building facilities to purchasing equipment.

The corporate bond market is large and liquid. Two markets buy and sell corporate bonds: the New York Stock Exchange (NYSE) and the over-the-counter (OTC) market. The OTC market is much bigger than the exchange market. Characteristics of investment grade corporates include:

  • Returns higher than Treasuries and agencies
  • Many maturities
  • Liquid market
  • All levels of risk available
  • Can be callable
  • May be secured or unsecured -- you will pay for the extra safety of a secured bond by receiving lower interest rates
  • Safety indicated by credit rating
  • Extensive research required
  • Interest is taxable

High Yield Bonds

High-yield bonds, also known as junk bonds, are corporate bonds issued by companies whose credit quality is below investment grade. Although they offer the possibility of higher returns, they also represent higher risks.

Issuers of high-yield bonds vary greatly. They can be emerging companies that don't have the history, size or capital strength required to receive an investment-grade rating, or former investment-grade companies that are experiencing hard times. Other issuers may be companies that are refinancing debt; companies that need capital to fund acquisitions or buyouts, or to fend off hostile takeovers; or even foreign governments and foreign corporations that need to attract capital. Characteristics of high-yields include:

  • Possibility of higher returns
  • Bigger and more kinds of risks than investment grade corporates
  • Often much harder to sell than investment grade
  • Low liquidity
  • Extensive research required
  • Interest is taxable
