Bonds: what are they and how do they work?

Bonds are a common investment instrument that investors use to generate income and diversify risk. They are debts issued by companies, local authorities or governments in order to raise capital. In exchange for their loan, investors receive regular interest payments until the principal is repaid on maturity.


How do bonds work?

When an investor buys a bond, they lend the issuer a certain amount of money in exchange for a promise of repayment. The bond has a predetermined lifespan, usually several years, during which the investor receives regular interest payments. When the bond matures, the investor gets the principal back.

The interest rate depends on the issuer's credit rating and market conditions. The more creditworthy the issuer, the lower the interest rate, as investors consider the investment safer.


Types of bonds

There are several types of bonds that investors can choose from, depending on their risk tolerance and investment strategy.

1. Government bonds

Governments issue bonds to finance public projects and operations. These bonds are considered very safe as they are backed by the state itself. All information about Icelandic government bonds can be found here.

2. Corporate bonds

Companies issue bonds to finance expansion, operations or other investment opportunities. They usually carry a higher interest rate than government bonds, as companies are considered riskier than governments.

3. Municipal bonds

Local authorities issue these bonds to finance infrastructure projects such as road construction and schools. They are often tax-exempt for investors, which makes them a popular option.

What affects the price of bonds?

Bond prices fluctuate according to many factors, including interest rate changes, the issuer's credit rating and market conditions.

  • Interest rate changes: When interest rates rise, bond prices fall, since new bonds are issued at higher rates and thus become more attractive. The opposite happens when interest rates fall; older bonds with higher yields become more valuable.
  • Credit rating: If an issuer's credit rating is downgraded, it can affect its ability to meet its obligations, which reduces investor confidence and lowers the price of the bonds.
  • Supply and demand: When investors want a safe investment, demand for bonds can increase and their prices can rise.

Why should investors buy bonds?

Bonds can be a good investment for those who want stable income with less risk than shares. The main advantages of bonds are:

  •  Regular interest payments – Investors receive a fixed interest rate over the life of the bond.
  • Lower risk than shares Bonds are generally considered safer than shares, especially government bonds.
  • A good way to spread risk By adding bonds to a portfolio, you can reduce risk and ensure stable returns.

What is the risk with bonds?

Although bonds are considered safer than shares, they carry a certain risk:

  • Credit risk: If the issuer of the bond encounters financial difficulties, it may be unable to meet its obligations.
  • Interest rate risk: Rising interest rates can lower bond prices and make them less attractive to investors.
  • Inflation risk: If inflation rises more than the bond's interest rate, the real yield can fall.

How to start investing in bonds?

For those who are starting out in bond investing, it is important to follow a few basic steps:
