Many South Africans want a steady income right now. Cash rates look decent, but inflation still hurts their personal finances and spending behaviour.
Shares can feel jumpy, and dividends can drop without warning. So people often view corporate bonds as a potential income-focused instrument, though they carry their own risks.

What is a corporate bond?

A corporate bond is a debt security issued by a company to raise capital for purposes such as expansion, operations, or acquisitions.

In other words, it is a loan you give to a company. The company promises to pay you (investor) interest, then repay your capital. 

In South Africa, the first corporate bond was issued in 1992, and since then, more than 1,500 corporate bonds have been listed on the JSE debt market. A listing can facilitate trading, since investors may exit before maturity.

Types Of Corporate Bonds

Not all corporate bonds work the same way. In the JSE Interest Rate Market, corporate debt comes in many forms. The main differences are the interest type, the structure, and the terms.

1) Fixed-rate corporate bonds

These types of bonds are issued by companies that pay the same interest rate over their entire term. They pay a set coupon for the life of the bond. Your cash flow stays stable, but the price can still move. Fixed-rate bonds are a common type listed on the JSE. These include Treasury, corporate, or municipal bonds, or certificates of deposit.

One key risk of this type of bond is the interest-rate risk.

2) Floating-rate Corporate Bonds

They are sometimes referred to as Floaters. These pay interest that resets over time, based on a reference rate. Also, these bonds are characterised by coupon rates that adjust periodically (3-6 months) based on a benchmark index with fixed spreads that can help reduce interest-rate risk when rates rise. 

When rates rise, the coupon usually rises at the next reset. Floating-rate bonds are also listed in the JSE corporate bond market. 

3) Corporate Inflation-linked Securities

Usually goes with the acronym CILS. And are sometimes called inflation-linked bonds. These are debt instruments designed to protect investors from inflation by adjusting coupon payments or principal value in line with an inflation index.

Payments adjust to inflation, rather than staying fixed. The JSE lists inflation-linked instruments in the corporate debt space. 

4) Zero-coupon corporate bonds

These do not pay regular coupons or interest payments. Instead, you (the investor) buy at a discount and receive the face value at maturity, providing you with a lump-sum payment. 

5) Convertible corporate bonds

These types of corporate bonds can be converted by the holder into a predetermined number of shares of the issuing company. Because they can be converted into stocks and thus benefit from the rise in the underlying stock’s price, companies offer lower yields on convertibles.

The JSE describes convertibles as debt with an equity conversion option.

Factors Controlling The Price Of Corporate Bonds

Below are the factors controlling the price of corporate bonds;

1) Market interest rates and the yield curve

Interest rates are the biggest driver for most bonds. When market yields rise, existing bond prices usually fall. When market yields fall, existing bond prices usually rise. Also, when market rates are higher, companies find it difficult to issue bonds because the yields required to drive demand are too high. This happens because future payments get discounted at new rates. 

2) Time to maturity and interest-rate sensitivity (duration)

Two bonds can face the same rate move and react differently. Longer-dated bonds often swing more in price. Duration is a simple number that indicates how sensitive a bond is to changes in interest rates. 

3) Credit risk and the credit spread

Corporate bonds usually trade at higher yields than government bonds because of default risk.
That extra yield is the credit spread. If investors feel the issuer is weaker, the spread widens and the price drops. If the issuer’s outlook improves, spreads can tighten, and prices can rise.

4) Inflation expectations 

Inflation affects what investors demand as compensation. If expected inflation rises, required nominal yields can rise too. That can pressure prices, mainly for fixed-rate bonds.

5) Coupon type and bond structure

The coupon design changes how a bond behaves.

• Fixed-rate: price tends to move more when rates change.
  
• Floating-rate: coupon resets, so the price often moves less with rates.
  
• Inflation-linked: price can react to inflation views and real yields.
  

6) Liquidity and bid–offer spreads

Some corporate bonds trade less often than government bonds. When trading is thin, investors may demand a discount to buy. Wider bid–offer spreads also reduce what you get when you sell. 

Where Corporate Bonds Trade in South Africa

The Johannesburg Stock Exchange (JSE) Debt Market is where many SA bonds are listed and traded. The JSE Debt market was formerly called the Bond Exchange of South Africa.

It covers government, bank, and corporate debt instruments. It supports price quotes and trading activity for listed bonds.

Primary vs secondary market

In the bond market, primary refers to a company issuing new bonds to investors for the first time to raise capital; secondary refers to investors trading existing bonds after they are listed on the JSE.

Risks and what to check first

While Corporate bonds can pay steady interest. But the risks can show up fast, often without warning. Below are some of the risks you’re likely to encounter;

1. Credit risk and downgrade risk

Credit risk means the issuer may miss or default on one or more interest payments or repay late before the bond reaches maturity. In that event, you may lose some or all of the investment principal

A downgrade can push the bond price down quickly, and yields will rise as investors demand higher risk premiums. Ratings help, but they are not a promise of payment. The analyst is indicating that the company’s future prospects have weakened. 

What to check first

• The issuer’s cash flow and debt load.
  
• Debt due dates and refinancing needs.
  
• The latest rating and any changes to the outlook.
  
• Where the bond ranks: senior or subordinated.

2. Interest-rate risk

When market rates rise, bond prices often fall. This matters most if you might sell before maturity. For instance, if the interest rate rises, the value of a bond or other fixed-income investment in the secondary market will decline. Holding bonds with different maturities may reduce overall interest-rate sensitivity. 

What to check first

• Fixed or floating rate coupon.
  
• Time to maturity and the bond or fund duration.
  
• Your holding period and when you may need cash.

3. Liquidity risk

Liquidity means being able to sell when you want, at a fair price. Some corporate bonds trade at lower yields than government bonds. In stressed markets, investors may struggle to sell quickly without accepting a significant discount.

What to check first

• How often does the bond trade?
  
• Typical trade size and the current bid and offer.
  
• Whether the issuer has many bonds or just one small issue.

4. Inflation risk and real return

Inflation poses a potent risk to corporate bonds by eroding the real purchasing power of interest payments and principal, often leading to negative real returns if inflation exceeds the nominal yield.

A high coupon can still lose buying power. Your real return is what you earn after inflation. If inflation rises, fixed income can quickly fall behind.

What to check first

• Your net yield after tax, fees, and spreads.
  
• Expected inflation versus that net yield.
  
• Whether you need inflation protection for long holding periods.
  

5. Friction and Fees

Friction cost refers to the total cost (obvious or hidden) incurred to execute a transaction. It helps an investor decide whether to proceed with a transaction.

What to check first

• Total expense ratio for funds, plus any platform fee.
  
• Bid-offer spread for direct bonds and bond ETFs.
  
• Any dealing fee, switching fee, or early exit charge.

Ways South Africans can get exposure

There are three main ways for South Africans to access corporate bonds. The appropriate route varies depending on factors such as control, costs, risk tolerance, and investment horizon.

Directly listed corporate bonds via intermediaries

You buy and own the bond itself. Pick a specific JSE-listed bond and place the trade through a broker or a bank desk. You pay broker fees, possible custody or platform fees, and the bid–offer spread. This suits investors who want a fixed maturity date and clearer cash flows.

Bond funds or bond ETFs

You own units in a fund or ETF, not individual bonds. A manager or an index holds many bonds in one pool, and ETFs trade on the JSE like shares. You usually pay an ongoing fund fee (TER) plus platform fees, and ETFs can also include spreads and brokerage. This suits investors who want diversification and smaller minimum amounts.

Trading bond CFDs for price exposure only (labelled)

You trade a derivative contract, not the bond. You aim to profit from bond price moves without owning the bond, and leverage can boost gains and losses. Costs can include the spread, overnight funding, and possible margin call costs. This suits short-term traders who understand leverage and can handle losses.

Where to find a list of corporate bonds in South Africa

Most lists cover bonds that are listed on the JSE Debt Market. If you need all listed instruments, use the JSE reference data files. 

1) Start with the JSE Bonds hub

The JSE Bonds page is the best public starting point. It is a simple directory into the bond market sections. 

2) Use the JSE Corporate Bonds page for the corporate segment

This page explains corporate bonds on the JSE Interest Rate Market. It helps you confirm you are looking at the right market segment. 

3) Check the JSE Client Portal for listings and updates

The Client Portal has a dedicated area for JSE Bond Listings. It also has a New Bond Listings page for recent listing notices. Some items may require portal access, depending on the page. 

4) For the most complete list, use JSE bond reference data products

The JSE offers a “Bonds Instrument Reference” data product. It provides reference data for listed debt instruments. It is available in structured formats like CSV and Excel. There is also a “New Bonds Listing” file for instruments being listed. 

5) Remember: not all corporate debt is listed

Some corporate debt is raised privately, not on the public bond board. JSE Private Placements supports private capital raises, including debt. 

Common mistakes: myths vs facts

Corporate bonds may look easy to you at first glance. Most errors come from skipping key checks.

1) Mistake: Thinking the coupon rate equals your return

Myth: The coupon rate is your true return.
Fact: Your return depends on the price you pay and the yield. If you sell early, the sale price can change your outcome. Bond prices and yields usually move in opposite directions.

2) Mistake: Ignoring liquidity and how you will exit

Myth: A listed bond is always easy to sell.
Fact: Some corporate bonds trade infrequently and can be hard to exit.
You may need to accept a discount to sell quickly. Trading depth often differs from government bonds.

3) Mistake: Chasing high yield without credit checks

Myth: The highest yield is the best choice.
Fact: High yield often signals higher default or downgrade risk. Ratings help, but they are opinions, not guarantees. A downgrade can hurt the price before any missed payment.

4) Mistake: Treating investing and CFD trading as the same thing

Myth: A bond fund and a bond CFD work the same way.
Fact: A CFD is a derivative contract, not bond ownership. Leverage can magnify gains and losses, and margin rules apply.

5) Mistake: Overlooking fees and trading “friction.”

Myth: The headline yield is what you will keep.
Fact: Costs reduce returns, sometimes by more than you expect. Funds charge ongoing fees like TER. Direct bonds and ETFs also face spreads and dealing costs.
