Having read yesterday’s post, you should now know what bonds are and that their price can differ from their par (face) value depending on various (mysterious) external circumstances. You have also read that after you’ve bought a bond its price only really concerns you if you’re planning to get rid of it before the maturity date. That’s a major difference to shares, whose price determines the value of your investment. With a bond on the other hand you can be certain that you will always get the bond’s par value back (assuming the issuer doesn’t default) plus any interest that might be payable ‘along the way’. This is the major reason why bonds should only constitute a small percentage of your portfolio while you’re young (i.e. you should make the most of your money rather than sit on a close-to risk-free bond)…

So what is it that influences the price you can sell your bond for?

• Interest rates: Rising interest rates mean you could potentially get a higher return even if your money is only sitting in a savings account. Therefore, bonds that issue after a rise in interest rates will offer a higher annual return (yield) in order to keep up with your savings account (and thus your bank!). This also means, the price for existing bonds might drop because their yield has now become less competitive and thus investors are willing to pay less. The only way to ‘convince’ investors to buy a bond with a low coupon rate, is by offering it at a discount. The same logic applies when interest rates drop - already issued bonds become more attractive and demand can only be limited via an increase in price.

• Inflation: When inflation increases, bond prices will decrease because the coupon rate might not be high enough to keep up with inflation. Especially with bonds that have a long maturity you will often find higher coupon rates to keep the bond attractive even if inflation might change substantially over the long run.
• Financial health of issuer: If the market believes that there is almost no risk of the issuer defaulting, the bond’s price will increase to reflect a high-quality security. On the other hand, if the investor is in some financial difficulties, not many people will be willing to accept the associated risk and the price will drop.

If you are keen to find out more about bonds (there is so much more material out there, trust me), I suggest you start here. There are many varieties of bonds available plus the option of investing in bond funds - i.e. a collection of bonds administered by someone who (hopefully) knows what they’re doing. The concepts are fairly similar to mutual funds so I will only cover them briefly next time.

All of the investment choices covered so far concern equity securities where the investor, after buying shares in one form or the other, owns part of a company. Debt securities constitute an alternative way for corporations (or governments!) of raising finance - without having to give up part of their company.

When you buy a bond you essentially make a loan to the corporation, the government or whoever else the bond’s issuer might be. Just like when you take out a loan with your bank, the issuer of the bond has to pay interest for being allowed to use your money.

Bonds are determined by three components: the par (or face) value, the coupon rate and the maturity. If an issuer wants to borrow £20,000 for 5 years and is willing to pay 7% interest on this money, the available bond will have a par value of £20,000, a coupon rate of 7% and a maturity of 5 years.

Issuers who want to keep the option of paying back back the face value before maturity, issue a callable bond, while issuers who don’t want to pay interest annually (or quarterly, monthly…) can create a zero-coupon bond. With this type of bond, no interest payments are being made during the loan period but the cumulated interest is paid together with the par value of the bond upon maturity. The advantage of the latter is that these bonds are usually priced at a discount to balance out the fact that no (interim) interest payments are made. This means, to buy a £1,000 bond you might only have to provide funds of £900, but the cumulative interest that you will receive upon maturity is based on the bond’s par value.

The coupon rate of the bond is mainly influenced by the current interest rate, the length of the term and the creditworthiness of the issuer. A company that has a relatively high risk of defaulting (i.e. not being able to pay back the loan) will have to pay higher coupon rates to balance this risk.

Because all of the above determinants can change after a bond is issued, the market value of a bond can and will vary over time. This variation is expressed as a percentage of the par value (i.e. 95% or 102%). Close to maturity, when interest rates and creditworthiness of the issuer won’t have sufficient time to adjust, the bond’s price will converge to 100% par value.

The good news is: if you buy a bond and plan to hold it until it matures, none of the above does affect you in any way. It just gets interesting once you’re trying to sell the bond on the secondary market (i.e. sell the right to receive interest payments from the issuer to some other investor).

More about the factors influencing bond prices soon (in case you don’t intend to hold on to the same bond for 20 years…).
