Currency Diversification ETF: What South African Investors Need to Know

The short answer: a currency diversification ETF gives you exposure to assets priced in dollars, euros, and other foreign currencies, reducing your dependence on the rand alone. For most South African investors with a long time horizon and a conviction that the rand will weaken over decades, it’s one of the most straightforward ways to hedge currency risk without opening a foreign brokerage account or navigating complex offshore transfers yourself.

I’ve advised clients on this decision for over a decade, and the question comes up consistently: should I hold some of my savings offshore? The answer almost always involves currency diversification ETFs, either through the JSE or via an offshore platform. This guide walks you through how they work, which types suit your situation, the tax rules you need to follow, and the risks you should not ignore.

Why Currency Risk Matters More Than Most South Africans Realise

Here’s the problem in plain terms: if all your wealth sits in rands, your financial security depends entirely on one currency’s performance against the rest of the world.

The rand is volatile. Over long periods, it has trended weaker against the US dollar and other major currencies, driven by inflation differences, political uncertainty, and South Africa’s structural current account deficit. That doesn’t mean it falls every single year. It can strengthen sharply and for extended periods. But the long-run pressure has generally favoured holding some capital offshore.

Think about what this means practically. You retire with R5 million in rand-denominated savings. Over the next decade, the rand weakens materially. Your rand balance may look stable or even grow on paper. But your ability to buy imported goods, travel, fund a child’s overseas education, or cover medical costs that track global pricing has declined. You can buy less with the same number of rands. The risk is invisible until it hits your lifestyle.

This is concentration risk by another name. You might be invested across many South African asset classes and sectors, yet you’re 100% concentrated in a single currency. A currency diversification ETF breaks that concentration without the friction of opening foreign accounts or managing cross-border transfers manually.

The practical implication for retirement planning is worth stating clearly: even a partial allocation to currency-diversified assets can meaningfully reduce the impact of rand weakness on your standard of living in retirement. This isn’t speculation. It’s prudent risk management.

For context on why concentration matters broadly, read about concentration risk and how it affects your portfolio. And if you’re thinking about building a full diversification strategy, that article on portfolio diversification sets out the principles that apply to currency exposure too.

How Currency Diversification ETFs Actually Work

The mechanism is simpler than most investors expect.

The most common route for South African retail investors is the JSE-listed feeder fund structure. An asset manager creates a South African fund, listed on the JSE and priced in rands. When you invest, your rand subscription gets converted into units in an underlying offshore fund, typically one that tracks a global index like the MSCI World or S&P 500. The underlying fund holds assets priced in dollars, euros, and other currencies. When you sell your JSE-listed units, the rand you receive reflects both what the underlying assets earned and how the rand moved against those currencies.

A concrete example: you invest R100,000 into a JSE-listed feeder ETF tracking a USD-denominated global equity index. The rand is trading at R18 to the dollar, so your R100,000 buys roughly $5,556 of the underlying fund. A year later, the index rises 10% in dollar terms, so your holding is now worth around $6,111. If the rand has stayed flat at R18, your investment is now worth about R110,000. But if the rand has weakened to R20 per dollar, your $6,111 converts back to approximately R122,220. The rand depreciation added to your return. The opposite happens if the rand strengthens: you’d show a lower rand return even if the index performed well.

The feeder fund structure means you don’t need to use your personal foreign capital allowance for most JSE-listed options, and you transact entirely in rands. If you want to explore other routes to offshore investing, this guide to investing offshore from South Africa covers the full range of options, including direct offshore platforms.

Types of Currency-Diversified ETFs Available to South African Investors

Not all offshore-exposure ETFs work the same way. The differences affect both your return profile and your planning decisions.

The broadest distinction is between unhedged and currency-hedged ETFs.

An unhedged ETF gives you full exposure to currency movements. If you hold a global equity ETF with no hedge, your rand return reflects both the underlying shares and the rand/dollar (or rand/euro) exchange rate. This is what most South African retail investors hold when they buy a JSE-listed global index tracker. Over the long run, it has generally been favourable given the rand’s historical weakness, but it introduces volatility in your rand returns even when the underlying index is calm.

A currency-hedged ETF uses financial instruments, typically forward contracts, to neutralise the exchange rate impact. You get roughly the same return as the underlying index in its base currency, converted at a locked rate. This removes currency volatility but also eliminates the upside from rand weakness. Hedged ETFs typically cost slightly more because the hedging mechanism carries fees.

Beyond that split, you’ll encounter several other types:

Global equity ETFs offer broad diversification across developed market shares, priced mainly in USD. These are the most widely available on the JSE.

Global bond ETFs give you exposure to foreign fixed-income markets. Less common on the JSE but available through offshore platforms.

Multi-asset or balanced global ETFs blend equities, bonds, and sometimes property in offshore currencies. Useful if you want a single diversified offshore holding.

Regional ETFs focus on specific regions such as the US, Europe, or Asia, rather than a global index.

On Shari’ah compliant options: a growing number of global Islamic equity ETFs exist, screening out interest-bearing businesses and other non-compliant sectors. These are worth considering if your values require it, and some are accessible to South African investors through offshore platforms or local feeder structures. Availability changes, so check current listings with your platform or adviser. For the broader case for currency diversification, the currency protection argument applies equally whether you use a conventional or Shari’ah compliant vehicle.

Quick Reference: Comparing Your Currency ETF Routes

Choosing the right option depends on your wrapper, your goals, and whether you need rand convenience or full offshore access. This table orients you quickly.

A few important notes on this table. Regulation 28 eligibility (the rule that limits how much of a retirement fund can sit in each asset class, to keep retirement savings diversified) depends on the specific fund’s structure and domicile, not just whether it’s JSE-listed. Always confirm with your retirement fund administrator or adviser before assuming a fund qualifies. For more on how Regulation 28 affects your retirement fund investments, that article explains the limits and how they apply to offshore exposure.

Tax and Regulatory Rules South African Investors Must Know

How you hold a currency diversification ETF determines its tax treatment. Getting this wrong costs you real money.

The three main wrappers have different tax outcomes.

Tax-free savings account (TFSA): Growth and income inside a TFSA are exempt from South African income tax and capital gains tax. This makes it an attractive wrapper for a JSE-listed global ETF, since both the currency return and the underlying asset return accumulate tax-free, subject to SARS annual and lifetime contribution limits. Check the current limits directly with SARS, as they shift with each budget.

Retirement annuity (RA): Contributions are tax-deductible within limits, and growth inside the fund is tax-free. However, Regulation 28 caps your offshore exposure. The allowable limit for offshore assets in a Regulation 28-compliant fund is set in the Pension Funds Act and has been updated in recent years. Verify the current figure with your RA provider, since it has shifted. The key point is that you can hold global ETFs inside an RA, but not without limits.

Taxable (discretionary) account: This is where the tax burden is highest. Foreign dividends received are subject to income tax in South Africa, not the dividend withholding tax rate that applies to local dividends. Capital gains on the sale of offshore ETF units are subject to capital gains tax, calculated using the rand/foreign currency exchange rate at the time of purchase and sale. A rand depreciation episode that boosts your rand return also inflates your taxable capital gain, which can be surprising at tax time.

Do not guess at exact rates. They change, and your marginal income tax bracket affects the outcome. Your obligation to report and pay tax on offshore holdings to SARS is real and applies even to JSE-listed feeder funds with offshore underlying assets.

Risks and Trade-Offs You Should Not Ignore

Currency diversification ETFs reduce one risk while introducing others. You need to understand both sides before investing.

Rand strengthening. If the rand strengthens meaningfully against the dollar or euro during your investment period, your rand return from an unhedged offshore ETF will lag the underlying index’s return in its base currency. You may even show a rand loss while the underlying fund shows a gain. This is not a reason to avoid currency diversification, but it is a reason to invest with a long time horizon and steady conviction.

Behavioural risk. This is the one most investors underestimate. Rand strength periods often produce underperformance in offshore ETF holdings measured in rands. Investors who bought for currency diversification then sell during those periods, locking in losses and abandoning the strategy at the worst moment. The currency cycle is long. Patience is not optional. It’s the mechanism through which long-run currency exposure works.

Tracking error and costs. Feeder fund structures add a layer of fees. You pay the underlying ETF’s total expense ratio plus the local feeder fund’s administration costs. These compound over time and reduce your net return. Check the fee structure before you invest.

Regulatory and tax complexity. The tax treatment of offshore ETF returns is more complex than local equity ETFs. Mishandling this is a real cost. A tax adviser can help you get it right, particularly if you’re in a higher tax bracket.

Concentration risk in reverse. Swinging from 100% rand to a heavily offshore-weighted portfolio replaces one concentration risk with another. Genuine diversification means balance. Understanding concentration of risk in your portfolio explains why the goal is balance, not substitution.

How to Add Currency Diversification ETFs to Your Portfolio

Adding a currency diversification ETF is straightforward in principle. The sequencing matters more than the choice of specific fund.

Step 1: Audit your existing currency exposure. Before buying anything, establish where you actually stand. If you’re a South African public servant, your GEPF (the Government Employees Pension Fund, the retirement fund for South African public servants) already holds meaningful offshore assets within its Regulation 28 limits. Many GEPF members don’t realise this and inadvertently over-allocate to offshore by adding personal offshore ETF exposure on top of what the GEPF already provides. Know your total picture first.

Step 2: Decide on your wrapper. TFSA first, if you have remaining lifetime capacity and a long time horizon. RA next, within Regulation 28 limits and only in funds that qualify. Taxable account for amounts beyond those wrappers, with tax planning built in.

Step 3: Choose between hedged and unhedged. For most investors with a long horizon and a conviction that rand weakness is a long-run trend, unhedged exposure makes sense. Hedged ETFs suit investors who want offshore asset class returns without currency volatility, such as those close to retirement who need predictable drawdown in rands.

Step 4: Set an allocation and review it periodically. There is no universally correct allocation. Your existing rand-denominated assets, your income needs, your tax position, and your time horizon all influence the right number. Use the retirement planning tool to model your offshore allocation before committing, and consider financial advice for building your retirement strategy if the allocation decision is material to your retirement income.

Frequently Asked Questions

What is the difference between a currency ETF and a currency-hedged ETF?

A currency ETF holds foreign-currency assets, giving you direct exposure to exchange rate movements alongside the underlying asset returns. A currency-hedged ETF also holds foreign assets but uses financial contracts to neutralise the exchange rate impact, so your return tracks the underlying index rather than the index plus currency movement. Most South African retail investors hold currency ETFs rather than hedged ones, though both types exist on the JSE and offshore platforms.

Can I hold a currency diversification ETF inside a South African retirement annuity?

Yes, provided the specific ETF is Regulation 28 compliant and your RA provider allows it. JSE-listed feeder funds that invest in offshore indices often qualify, but you must confirm with your provider. The offshore allocation within an RA is capped by Regulation 28 limits, which have been updated in recent years. Always verify the current limit before assuming a particular fund qualifies for your RA.

Are currency diversification ETFs suitable for retirees drawing down income?

They can be, but the sequencing of withdrawals matters. If you’re drawing a living annuity drawdown (a retirement income product where you stay invested and draw an income you choose within set limits; the remaining balance can pass to your beneficiaries) and your offshore ETF falls in rand value during a rand-strength period, selling units to fund income locks in that underperformance. A blended approach, with some rand-denominated income-generating assets alongside offshore growth assets, often works better in retirement than a pure offshore allocation. Consider this carefully before restructuring a drawdown portfolio. For more on this, read about living vs life annuity when planning to retire abroad.

Do I need to declare offshore ETF holdings to SARS?

Yes. Even JSE-listed ETFs with offshore underlying assets generate income and capital gains that must be declared to SARS. Your asset manager or platform will issue a tax certificate, but it’s your responsibility to ensure it’s included in your tax return. For directly held offshore ETFs, the disclosure obligations are more extensive and you may need to work with a tax adviser to get the reporting right.

What allocation to currency-diversified ETFs is typical?

There is no single correct figure. A general principle is that your offshore allocation should reflect your need for currency protection relative to your existing rand assets and your income requirements. Timing your investment decisions matters less than getting the allocation right and staying consistent. A fee-charging financial adviser can help you model the appropriate range for your specific situation.

What happens to my offshore ETF if I emigrate from South Africa?

Your tax and reporting obligations change when you emigrate, but you can typically keep holding the ETF. The complexity depends on where you’re emigrating to and whether that country has a tax treaty with South Africa. If this is a real possibility for you, discuss it with a tax adviser who understands cross-border tax implications before you invest.

How often should I rebalance between rand and offshore holdings?

There’s no fixed schedule. Most investors rebalance when their target allocation drifts materially out of range, say by 5% or more. If you’ve set a 30% offshore allocation and rand weakness pushes it to 35%, you might rebalance by shifting new contributions or selling some offshore holdings to buy rand assets. The important thing is not to rebalance based on currency forecasts. Stick to a mechanical rule tied to your target allocation.

The Bottom Line on Currency Diversification ETFs

A currency diversification ETF is one of the most accessible tools available to South African investors who want to reduce their dependence on the rand.

Three decisions shape your outcome: the wrapper you use, whether you choose hedged or unhedged exposure, and the allocation you set relative to your existing rand assets. Get those three right and the specific fund matters less than the discipline of staying invested through rand-strength cycles.

Before you add any new currency ETF exposure, review your existing portfolio for rand concentration. Many investors are more exposed to the rand than they realise, and some, particularly GEPF members, already have more offshore exposure than they know. That audit comes first.

For a broader framework, build a complete portfolio diversification strategy that positions currency exposure within your full asset allocation. If you want guidance tailored to your own numbers, find a financial adviser for your retirement plan who can model the rand, tax, and Regulation 28 implications for your specific situation.
