5 things every investor should know about fixed income

Fixed income securities (often referred to as bonds) are a form of debt. They have different characteristics to other investments such as shares and property, which can make them a valuable addition to a portfolio. Here we outline five key facts about the asset class.

1. The benefits of investing

A well-diversified, actively managed fixed income fund plays an important role in a client’s overall investment strategy regardless of the market environment. Benefits such as protection of capital, income generation and diversification can make an investment in fixed income an attractive option for investors.

Capital protection

Fixed income investments can be appealing to risk-averse investors such as those nearing or in retirement. A diversified portfolio of fixed income securities tends to be much less volatile than an equity portfolio, which means it is less likely to incur large losses in a short period of time. The basic principle of fixed income securities is the repayment of principal at maturity. Investors are repaid the amount of money they originally invested at the end of the agreed period.

Income generation

While many investments provide some form of income, fixed income investments tend to offer attractive and reliable income streams. Most importantly, a diversified fixed income portfolio can provide income with a lower level of risk than equities, and may offer higher income than money market funds or term deposits.


As fixed income assets often perform well at different times to equities, they can help to provide portfolio diversification, which over the long-term can provide investors with better risk-adjusted returns.

2. Types of fixed income

Fixed income is a broad asset class. Among the types of fixed income securities investors can choose from are government and agency securities, municipal bonds, corporate bonds, and asset-backed securities such as mortgage-backed bonds.

The yield is generally higher for corporate bonds compared to that of government bonds. This is because the perceived risk for investing in corporate bonds is higher. Mortgage-backed bonds have a yield that typically exceeds high-grade corporate bonds with comparable maturity, and have a low credit risk.

Type Description
Government Government bonds are also known as Sovereigns and Treasuries. Governments issue bonds to pay for government activities and pay off their debt obligations.
Agency Government agencies issue bonds to support their mandates, typically to ensure that various constituencies have access to sufficient credit at affordable rates.
Corporate Corporate bonds are also referred to as credit. Corporations issue bonds to expand, modernise, cover expenses and finance other activities.
Asset-backed Banks and other lending institutions pool assets, such as mortgages, and offer them as security to investors. This raises money so the institutions can offer more mortgages.

Within corporate bonds, there are a number of classes of debt, ranging from senior bonds to preferred securities. Senior bonds have greater seniority in the issuer’s capital structure than subordinated debt and preferred securities. This means that in the event the issuer goes bankrupt, senior debt must be repaid before other creditors receive any payment. Senior debt is often secured by collateral on which the lender has put in place a ‘first lien’ or legal right to secure the payment of debt.

3. The relationship between price and yield

If an investor purchases a new bond with the view of keeping it to maturity, then any change in the price of the bond, interest rates or yields would not be relevant. However, if an investor buys or sells an existing bond, the price that the market is willing to pay for the bond may fluctuate. As a result, the bond’s yield (i.e. the expected return on the bond) may also change.

The first, and most important, concept to understand when discussing bond yields is that bond prices and yields have an inverse relationship. That is, when bond prices go up, bond yields go down and vice versa. To understand why this is, it helps to see bond yields as a measure of the profit from a bond investment. The less investors pay for the bond, the greater their profit is likely to be and the higher their yield. Conversely, the more investors pay for a bond, the smaller their likely profit and the lower their yield.


4. The main drivers of bond prices

There are three main drivers of bond prices: inflation, interest rates and the financial health of the issuer.

5. The importance of active management

By investing in an actively managed, diversified bond fund investors are able to spread portfolio risk. When investors have exposure to only a small number of securities this exposes them to a concentrated risk in issuers, industries or geographies, and a systemic event can impact a large part of the portfolio. Active bond managers will commonly adjust a bond portfolio’s duration to protect the capital value of the fund.

For example, a bond manager expecting interest rates to fall would normally ‘lengthen’ the portfolio’s duration by buying longer-term bonds and selling shorter-term bonds. This is because, in this circumstance, the price of a longer duration portfolio should rise more than that of a shorter duration portfolio. Bond prices can sometimes increase significantly more than ‘par’, and in the extreme case of a company defaulting, prices can fall to zero. That is why, unlike equities where one poor performing stock can be compensated with a strong performing stock, bond risk needs to be spread widely.
