Bonds

What is a bond?

A bond is a debt security, similar to an IOU. When you purchase a bond, you are lending money to a government, municipality, corporation, federal agency, or other entity known as the issuer. In return for the loan, the issuer promises to pay you a specified rate of interest during the life of the bond and to repay the face value of the bond (the principal) when it "matures," or comes due. In contrast to bondholders who have IOUs from the issuer, shareholders are owners of the company they purchase.

There are many different kinds of bonds, including: U.S. government securities, municipal bonds, corporate bonds, mortgage and asset-backed securities, federal agency securities, and foreign government bonds. (Source: SEC)

In finance, a bond is a debt security, in which the issuer owes the holders a debt and is obliged to repay the principal and interest (the coupon) at a later date, termed maturity. Other stipulations may also be attached to the bond issue, such as the obligation for the issuer to provide certain information to the bond holder, or limitations on the behavior of the issuer. Bonds are generally issued for a fixed term (the maturity) longer than ten years. U.S Treasury securities issued debt with life of ten years or more is a bond. New debt between one year and ten years is a note, and new debt less than a year is a bill.

A bond is simply a loan, but in the form of a security, although terminology used is rather different. The issuer is equivalent to the borrower, the bond holder to the lender, and the coupon to the interest. Bonds enable the issuer to finance long-term investments with external funds. Debt securities with a maturity shorter than one year are typically bills. Certificates of deposit (CDs) or commercial paper are considered money market instruments.

Traditionally, the U.S. Treasury uses the word bond only for their issues with a maturity longer than ten years, and calls issues between one and ten year notes. Elsewhere in the market this distinction has disappeared, and both bonds and notes are used irrespective of the maturity. Market participants normally use bonds for large issues offered to a wide public, and notes for smaller issues originally sold to a limited number of investors. There are no clear demarcations. There are also "bills" which usually denote fixed income securities with three years or less, from the issue date, to maturity. Bonds have the highest risk, notes are the second highest risk, and bills have the least risk. This is due to a statistical measure called duration, where lower durations have less risk, and are associated with shorter term obligations.

Bonds and stocks are both securities, but the difference is that stock holders own a part of the issuing company (have an equity stake), whereas bond holders are in essence lenders to the issuer. Also bonds usually have a defined term, or maturity, after which the bond is redeemed whereas stocks may be outstanding indefinitely. An exception is a consol bond, which is a perpetuity, a bond with no maturity.

Bonds are issued by public authorities, credit institutions, companies and supranational institutions in the primary markets. The most common process of issuing bonds is through underwriting. In underwriting, one or more securities firms or banks, forming a syndicate, buy an entire issue of bonds from an issuer and re-sell them to investors. Government bonds are typically auctioned.

Bonds markets, unlike stock or share markets, often do not have a centralized exchange or trading system. Rather, in most developed bond markets such as the U.S., Japan and western Europe, bonds trade in decentralized, dealer-based over-the-counter markets. In such a market, market liquidity is provided by dealers and other market participants committing risk capital to trading activity. In the bond market, when an investor buys or sells a bond, the counterparty to the trade is almost always a bank or securities firm acting as a dealer. In some cases, when a dealer buys a bond from an investor, the dealer carries the bond "in inventory." The dealer's position is then subject to risks of price fluctuation. In other cases, the dealer immediately resells the bond to another investor.

Bond markets also differ from stock markets in that investors generally do not pay brokerage commissions to dealers with whom they buy or sell bonds. Rather, dealers earn revenue for trading with their investor customers by means of the spread, or difference, between the price at which the dealer buys a bond from one investor--the "bid" price--and the price at which he or she sells the same bond to another investor--the "ask" or "offer" price. The bid/offer spread represents the total transaction cost associated with transferring a bond from one investor to another.

Bonds are bought and traded mostly by institutions like pension funds, insurance companies and banks. Most individuals who want to own bonds do so through bond funds. Still, in the U.S., nearly ten percent of all bonds outstanding are held directly by households.

A number of bond indices exist for the purposes of managing portfolios and measuring performance, similar to the S&P 500 or Russell Indexes for stocks. The most common American benchmarks are the Lehman Aggregate, Citigroup BIG and Merrill Lynch Domestic Master. Most indices are parts of families of broader indices that can be used to measure global bond portfolios, or may be further subdivided by maturity and/or sector for managing specialized portfolios.
