JSE vs international stocks: where should a South African invest?

The starting point: how small South Africa is

South Africa represents well under 1% of global stock market value. That is not a criticism of the JSE - it is arithmetic. It means an investor holding only local shares has concentrated essentially all of their equity exposure into a fraction of a percent of the world's listed companies.

Now add everything else. Your salary is in rand. Your property, if you own any, is in South Africa. Your retirement fund is largely local by regulation. Your medical aid, your school fees, your municipal rates - all rand, all exposed to one economy.

Seen that way, the question is not "should I invest offshore?" but "how much of my total financial life is already tied to a single country?" For most South Africans the honest answer is nearly all of it.

What the JSE actually gives you

The JSE has real strengths and they are frequently understated:

• No currency conversion. You buy in rand, you sell in rand, you pay no forex spread. Over a lifetime of monthly contributions this is worth more than it sounds.
• It is well-regulated and liquid at the large-cap end, with a long history and mature market infrastructure.
• Simple tax treatment. Local dividends are handled by withholding at source, and everything is already denominated in rand for your return. See how investment tax works in South Africa.
• It can sit in a TFSA. JSE-listed shares and approved ETFs go inside a tax-free savings account. A direct offshore brokerage account cannot.
• You understand the companies. You shop at these retailers and bank with these banks. That familiarity has limits, but it is not worthless.

And its real weaknesses

• Concentration. A large share of the index sits in resources, financials and a handful of very large companies. When one sector or one company has a bad year, the whole index feels it.
• Sector gaps. The technology, biotech and consumer-tech sectors that dominate global indices are barely represented locally.
• Fewer listings. The number of companies listed on the JSE has declined over the years, narrowing the opportunity set.
• Economic exposure. Domestic retailers, banks and industrials are tied to South African growth, electricity supply, logistics and consumer strength.

The rand hedge complication

Here is the part that makes this genuinely interesting: a meaningful portion of the JSE is not really a bet on South Africa at all.

Several of the largest JSE-listed companies earn most of their revenue outside the country - resources groups selling commodities priced in dollars, and multinationals with the bulk of their operations abroad. These are commonly called rand hedges, because when the rand weakens their foreign earnings translate into more rand.

The consequence: if you buy a broad JSE index, you already have substantial indirect offshore exposure. You are not as locally concentrated as the label suggests.

But this cuts both ways. That exposure is indirect and comes bundled with specific company and commodity risk. Holding a mining group is not the same as holding a globally diversified index - you are exposed to iron ore prices and one management team's decisions, not to global economic growth generally. Our guide to what moves the rand covers the currency mechanics.

What global markets give you

• Breadth. A global index fund holds thousands of companies across dozens of countries and every major sector. That is diversification of a kind the JSE structurally cannot offer.
• Access to sectors that barely exist here. The world's largest technology, pharmaceutical and consumer companies are listed elsewhere.
• Currency diversification. Holding assets in dollars, euros and yen means your savings do not rise and fall entirely with one currency.
• Independence from local politics and policy. Not because South Africa is uniquely risky, but because concentration in any single country is a risk.

The costs are real too: currency conversion spreads if you go direct, exposure to rand strength working against you, and potentially more complex tax and record-keeping. See what it costs to buy US stocks from South Africa.

Comparing them honestly

How to think about the split

There is no universally correct ratio, and anyone stating one with confidence is overselling. But a few principles hold up:

• Count your whole financial life, not just your portfolio. Salary, property and retirement fund are all local exposure. Your discretionary investments are often the only place you can correct the imbalance.
• Remember Regulation 28. Retirement fund money is capped in how much can go offshore. If a large share of your wealth sits in an RA or pension fund, that portion is structurally local - which argues for weighting your TFSA and discretionary money more heavily global.
• Do not double-count rand hedges. A JSE index gives you some offshore earnings exposure, but treating that as equivalent to global diversification overstates it.
• Global does not mean US-only. A world index fund includes Europe, Japan, the UK and emerging markets. Buying only US shares is a country bet too, just a different country.
• Do not try to time the rand. Moving money offshore because the rand looks weak, or holding back because it looks strong, is currency speculation. Almost nobody wins at it consistently.

The goal is not to pick the market that will do best. It is to own enough of the world that you do not need to know which one will.

The practical route

For most South Africans, the simplest way to hold both is entirely on the JSE:

1. A broad global or world index ETF listed on the JSE, bought in rand. No forex, no offshore allowance paperwork, and TFSA-eligible if approved.
2. A broad JSE index ETF for local exposure, again in rand.
3. Adjust the ratio between them as your circumstances change, using new contributions rather than selling - see how to rebalance.

This gives you genuine global diversification without ever opening an offshore account. Our guide to buying an ETF in South Africa covers the mechanics, and how to start investing on the JSE covers the account setup.

Go direct offshore when you have a specific reason: you want to own particular foreign companies, or you want genuine dollar assets held outside South Africa. Both are valid. Neither is required for global diversification, which is what most people actually want. See how to buy US stocks from South Africa for that route.

See your real exposure

Most people are surprised by their actual geographic mix once they see everything in one place - including how much of their "local" holdings earn abroad.

Frequently asked questions

How much of my portfolio should be offshore?

There is no single correct answer, but many South African investors hold a substantial portion of their growth assets globally, on the reasoning that South Africa is a small fraction of global market value while representing all of their income, property and currency exposure. Your retirement fund is capped by Regulation 28, so discretionary money often carries the offshore weight.

What is a rand hedge stock?

A JSE-listed company that earns most of its revenue in foreign currency, so its rand earnings rise when the rand weakens. Several of the JSE's largest companies fall into this category, which means holding a JSE index already gives you meaningful indirect offshore exposure - more than the label suggests.

Is the JSE too concentrated to rely on?

It is significantly more concentrated than global indices, with a large share of value in resources, financials and a small number of very large companies. That is not a reason to avoid it, but it is a strong reason not to hold it alone - concentration means single-sector or single-company events move the whole index.

Does Regulation 28 limit how much I can invest offshore?

It limits retirement fund money - retirement annuities, pension and provident funds - not your total investing. Discretionary investments and tax-free savings accounts are not subject to Regulation 28, so many investors deliberately hold more offshore exposure there to balance the caps in their retirement fund.

Should I buy offshore exposure through the JSE or through an offshore broker?

For most investors, JSE-listed global ETFs are simpler and cheaper - no currency conversion, no offshore allowance paperwork, and they can sit in a tax-free savings account. A direct offshore broker makes sense if you want to own specific foreign companies or hold genuine dollar assets outside South Africa.
