What Is an ETF?

What Is an ETF?

An exchange-traded fund (ETF) is a listed investment vehicle that holds a basket of underlying assets, such as equities, bonds, commodities, or property, and trades on a stock exchange in the same way a single share does. Investors buy and sell units throughout the trading day at market prices, and each unit represents a proportional stake in the fund's underlying portfolio. In South Africa, ETFs are listed on the Johannesburg Stock Exchange (JSE) and are regulated by the Financial Sector Conduct Authority (FSCA) under the Collective Investment Schemes Control Act (CISCA).

The defining characteristic of most ETFs is passive management: the fund tracks a published index rather than relying on a portfolio manager to select individual securities. This structural simplicity keeps costs low and makes the return profile transparent and predictable relative to the benchmark.

How an ETF Works in Practice

Creation and Redemption

ETFs maintain price alignment with their underlying assets through an authorised participant (AP) mechanism. Large institutional counterparties can create new ETF units by delivering the underlying basket of securities to the fund, or redeem existing units in exchange for those securities. This arbitrage process keeps the ETF's market price close to its net asset value (NAV) throughout the trading day.

For retail investors on the JSE, the mechanics are simpler: you place a buy or sell order through a stockbroker or online trading platform, and the trade settles in the normal equity settlement cycle (currently T+3 in South Africa).

Index Tracking

Most South African ETFs track a defined index. The fund's mandate specifies the index, the replication method (physical or synthetic), and the permitted tracking error. Physical replication means the fund actually holds the constituent securities. Synthetic replication uses derivatives to replicate index returns, which introduces counterparty risk and is less common in the South African retail ETF market.

Tracking difference, the gap between the ETF's actual return and the index return over a period, is a more useful performance measure than the stated tracking error. A well-managed physical ETF should have a tracking difference close to zero or even slightly positive when securities lending income offsets costs.

The South African ETF Market

A Market That Has Matured Quickly

South Africa launched its first ETF in 2000 with the Satrix 40, which tracks the FTSE/JSE Top 40 Index. The market has since expanded to include several dozen listed products spanning domestic equities, global equities, fixed income, listed property, commodities (including gold), and multi-asset funds. Total assets under management in locally listed ETFs have grown substantially over the past decade, driven by cost-conscious investors, growing financial literacy, and the structural shift toward passive investing that has played out globally.

The JSE's ETF segment is one of the largest and most liquid in Africa, making it the natural starting point for any South African investor considering index-based investing.

Key Providers

The main ETF issuers active on the JSE include Satrix (a subsidiary of Sanlam), Absa (through its NewFunds range), 1nvest (a partnership between Standard Bank and African Rainbow Capital), and Ashburton Investments (FirstRand). A number of global issuers, including iShares and Vanguard, have products accessible to South African investors through rand-denominated feeder ETFs or directly via offshore platforms, though cross-border investing carries foreign exchange and regulatory considerations.

Costs: The Central Advantage

The total expense ratio (TER) is the annual cost expressed as a percentage of the fund's assets. For passive ETFs on the JSE, TERs typically range from roughly 0.10% to 0.40% per year for broad domestic equity products, rising to 0.50% to 0.75% for more specialised or global-exposure funds. Active unit trusts in South Africa frequently carry TERs of 1.00% to 1.75% or higher.

Over a 20-year investment horizon, a 1% annual cost difference compounds into a material reduction in terminal wealth. This arithmetic, not marketing, is why passive ETF investing has attracted sustained attention from both retail and institutional investors.

Beyond the TER, investors should account for brokerage commissions, the bid-ask spread on the JSE, and any platform administration fees charged by their broker or investment account provider.

Building an ETF Portfolio in South Africa

Defining Your Objectives First

An ETF is a vehicle, not a strategy. Before selecting any product, an investor or adviser should establish the investment objective (growth, income, capital preservation, or a blend), the time horizon, the required liquidity, and the risk tolerance. These parameters determine asset class allocation, which in turn determines which ETFs are appropriate.

Asset Class Building Blocks

A typical South African ETF portfolio draws from several building blocks:

Domestic equities. Broad market exposure to the JSE is available through ETFs tracking the FTSE/JSE All Share Index (ALSI), the FTSE/JSE Top 40, or the FTSE/JSE Capped SWIX. The Capped SWIX is widely used in institutional portfolios because it limits single-stock concentration and applies a shareholder-weighted methodology that reduces the distortion caused by dual-listed mining and resources companies.

Global equities. Rand-denominated ETFs that hold global indices (such as the MSCI World or S&P 500) allow South African investors to gain offshore exposure without opening a foreign account or using their annual foreign investment allowance directly. The currency exposure is embedded: when the rand weakens, the rand value of these ETFs rises, and vice versa. This dual exposure to equity markets and the rand/dollar exchange rate is a feature, not a flaw, for investors seeking portfolio diversification.

Fixed income. Government bond ETFs (tracking the JSE All Bond Index or specific maturity segments) and inflation-linked bond ETFs provide income and lower volatility relative to equities. They are relevant for investors approaching retirement or managing liability-matched portfolios.

Listed property. South African REIT ETFs track the FTSE/JSE SA Listed Property Index. Listed property has historically offered income yields above cash and bonds, though the sector experienced significant capital losses during and after the COVID-19 period and has been recovering unevenly.

Commodities. Gold ETFs backed by physical gold (stored in vaulted form) are available on the JSE. Gold provides a hedge against currency weakness and systemic risk, though it generates no income.

Regulation 28 and Retirement Funds

If you are investing through a retirement annuity (RA), pension fund, or provident fund, your portfolio must comply with Regulation 28 of the Pension Funds Act. Regulation 28 sets maximum exposure limits by asset class and geography. For example, it caps offshore exposure (equities plus other offshore assets) at a specified percentage of the portfolio. These limits are set by National Treasury and reviewed periodically; investors should confirm current limits with their fund administrator or the FSCA rather than relying on any specific figure here, as they have been adjusted in recent years.

Many ETF providers offer Regulation 28-compliant multi-asset ETFs or model portfolios specifically designed for the retirement savings context.

Tax Considerations for South African ETF Investors

The tax treatment of ETF returns in South Africa depends on the nature of the income and the investor's classification:

• Dividends distributed by South African ETFs are subject to dividends tax at the applicable rate, withheld at source. Foreign dividends distributed through a rand-denominated feeder ETF may be taxed differently; the fund's minimum distribution statement (MDS) provides the breakdown.
• Interest distributed by bond ETFs is taxed as ordinary income in the hands of the investor, subject to the annual interest exemption available to natural persons under a certain age threshold.
• Capital gains on the disposal of ETF units are included in the investor's capital gains tax (CGT) calculation, subject to the annual exclusion for natural persons. The inclusion rate and maximum effective CGT rate for individuals are set by SARS and are subject to change in the annual Budget. Confirm current rates at sars.gov.za.

Investing through a tax-free savings account (TFSA) eliminates dividends tax, interest tax, and CGT on returns within the account, subject to the annual and lifetime contribution limits set by SARS. ETFs are one of the most efficient instruments to hold inside a TFSA because their low costs and broad diversification align well with the long-term, tax-sheltered nature of the account.

ETF Trading in South Africa: Practical Mechanics

How to Buy an ETF on the JSE

You need a JSE-linked brokerage account or an investment platform that provides access to the JSE ETF segment. Options range from full-service stockbrokers to low-cost online platforms. Once your account is funded, you search for the ETF by its JSE ticker code (for example, STX40 for the Satrix 40 ETF), place a limit or market order, and the trade executes during JSE trading hours (09:00 to 17:00 SAST on business days).

Many platforms also offer a debit order or recurring investment facility, allowing you to invest a fixed rand amount monthly. This approach implements rand-cost averaging: you buy more units when prices are low and fewer when prices are high, smoothing your average entry cost over time.

Liquidity and Spreads

Liquidity varies across JSE-listed ETFs. The largest and most widely traded products (broad equity ETFs from established issuers) have tight bid-ask spreads and high daily volumes. Smaller, more specialised ETFs may have wider spreads, meaning the difference between the price at which you can buy and the price at which you can sell is larger. For long-term investors this spread cost is a one-time entry and exit cost; for frequent traders it becomes material.

Evaluating ETF Performance in South Africa

What "Best Performing" Actually Means

Searches for the best performing ETF in South Africa typically surface recent short-term return tables. These can be misleading. An ETF that returned 40% in a single year because it holds a concentrated sector (technology, gold miners, or a specific geography) may have also delivered a 30% loss in a prior year. Past performance, particularly over short periods, reflects the performance of the underlying index, not the quality of the ETF structure itself.

A more useful evaluation framework looks at:

1. Tracking difference over at least three years: does the ETF deliver the index return net of costs?
2. TER and transaction costs: what is the all-in cost of holding the product?
3. Index construction: what does the underlying index actually hold, and does that match your intended exposure?
4. Fund size and liquidity: is the fund large enough to be sustainable and liquid enough to trade efficiently?
5. Issuer credibility and regulatory standing: is the fund registered with the FSCA and administered by a reputable counterparty?

Broad Market vs. Thematic ETFs

Broad market ETFs (tracking the ALSI or Top 40) have historically delivered returns consistent with the JSE's long-run equity risk premium. Thematic or sector ETFs (focused on technology, ESG-screened indices, or specific commodities) offer targeted exposure but introduce concentration risk. Neither is inherently superior; the appropriate choice depends on the role the ETF plays within a broader portfolio.

---

ETFs vs. Unit Trusts in South Africa

Both ETFs and unit trusts are regulated collective investment schemes under CISCA, and both pool investor capital into a diversified portfolio. The practical differences are:

| Feature | ETF | Unit Trust | |---|---|---| | Trading | Intraday on JSE at market price | End-of-day at NAV | | Minimum investment | One unit (often a few rand to a few hundred rand) | Typically R500 to R1,000 minimum lump sum | | Management style | Predominantly passive | Passive and active options | | Cost (TER) | Generally lower for passive products | Variable; active funds typically higher | | Tax-free account eligible | Yes | Yes |

For most long-term investors, the choice between a passive ETF and a passive index unit trust tracking the same index comes down to cost, platform availability, and whether intraday trading flexibility matters to them.

A Note for Institutional and Adviser Use

For investment professionals managing model portfolios, discretionary mandates, or retirement fund assets, ETFs serve as efficient building blocks. Their daily NAV transparency, real-time pricing, low TERs, and CISCA regulatory status make them straightforward to incorporate into compliance and reporting frameworks. Portfolio administration platforms that provide consolidated ETF holdings data, accurate cost-basis tracking, and Regulation 28 monitoring materially reduce the operational burden of managing multi-asset ETF portfolios at scale.
