Why not just invest in South Africa

By Charize Beukes* 

It's one of the questions I hear most often, and a fair one: why invest offshore when you live in South Africa, earn in rands, and understand the local companies well?

I'll admit it, the JSE has served investors well recently. Over the past 10 years it has returned close to 12% a year in rand, comfortably ahead of local inflation. This performance means that R100,000 invested a decade ago in a JSE tracker is worth roughly R308,000 today. 

So, yes, local assets remain essential, for the simplest of reasons: your everyday expenses are in rands, and local investments are the natural match for them.

So the real question isn't whether South Africa has good investments. It clearly does. The question is whether one relatively small, concentrated market should carry such responsibility for funding your retirement, protecting your buying power, and supporting the people who come after you. 

For most people, the honest answer is not on its own.

Your portfolio should not mirror your passport

Most South Africans already hold a significant bet on South Africa before they open an investment statement. Your income is earned here. Your home is here. Most of your retirement capital sits inside local rules and institutions, and most of what you'll spend in future is priced in rands.

Filling the rest of your portfolio with more local assets doesn't reduce that concentration, it adds to it. 

Offshore assets work as a counterweight by investing in companies that earn across many regions, in several currencies, at different points in the economic cycle. 

The risk in having a strong home bias isn't that South Africa might struggle. It's simply that too much of your financial life can rise or fall as a result.

A big fish in a small pond

Size is the first issue. The FTSE/JSE All Share Index holds around 119 shares. The MSCI ACWI, a broad global index, holds close to 2,461 stocks and still captures only about 85% of the world's investable market. 

It’s a well-known fact that South Africa makes up well under 1% of global listed equity.

Concentration is the second issue. The 10 largest JSE shares make up close to half the entire local market. Financials and basic materials alone account for close to 60% of the JSE, which leaves a local-only investor heavily exposed to a handful of banks and miners, the gold price, and the rand.

The pond is shrinking too. The number of companies listed in South Africa has fallen from around 740 in 1990 to roughly 212 today. 

Fewer listings mean fewer choices, and a greater chance that local portfolios crowd into the same handful of large shares, missing entirely the software, healthcare, semiconductor, and global consumer businesses that barely exist on the JSE.

This is not a bet against South Africa. It is a realistic view of concentration. South Africa is one country, one currency, and a narrow stock market, and your future is too important to depend on a single economic and political outcome, however familiar it feels. Invest locally where the opportunity is attractive and the expense is in rands. Invest globally because your wealth deserves more than one route to success.

The rand is a risk, and a diversifier

Currency isn't the whole offshore story, but it can't be ignored. In 2011, around R6.70 bought a US dollar. Today it takes roughly R16.50, a decline of close to 60% over 15 years, or about 6% a year.

This matters because so much of what you'll eventually spend on, international travel, imported goods, medical technology, children studying abroad, is priced in hard currency. 

As we all know, the rand can strengthen as well as weaken, and a stronger rand reduces offshore returns in the short term, so the aim isn't to gamble on the exchange rate. It's to avoid having every asset and every future expense depend on the same one. 

Phasing money offshore steadily over time is a far more sensible approach than trying to time the perfect moment.

When you translate returns into a hard currency, the local picture shifts. Over the past fifteen years the S&P 500 compounded at close to 14% a year in dollars. Measured in the same dollars, the JSE delivered far less, because much of its rand return was offset by the weaker currency. A few percentage points a year, compounded over fifteen years, becomes a very large difference in the end.

The strongest objections, answered honestly

Here's how I think about the most common concerns clients raise.

A more generous offshore allowance

In the 2026 Budget, the single discretionary allowance doubled from R1 million to R2 million per adult per calendar year, effective from April 2026. The foreign capital allowance remains R10 million per adult per year, subject to tax clearance.

Why this matters is that structure is as important as your decision to go offshore. A rand-denominated global fund isn't the same as money physically externalised, even when the underlying investments look similar. 

Tax, estate planning, offshore situs exposure, platform costs, and access to capital all need to be weighed properly, and that's exactly where I can help you choose the right route.
