Stock index ETF

Rules, protection and tax below are for South Africa.

What it is

An ETF that holds every company in an index, in the same proportions, and trades on the exchange like a share. There is no manager choosing stocks, just a rule, which is why the ongoing charge can be a tenth of an active fund's.

This is the instrument behind most of the honest advice you will ever read: buy the whole market cheaply, add to it regularly, and hold for decades. It captures the long-run growth of business without betting on which businesses.

It is still shares. A world index has fallen by half in a bad crash and taken years to recover. The reason it works is that people who kept adding through those years ended up well ahead; the reason it fails is that people sell at the bottom.

How it works

  1. The fund buys the index's constituents and issues shares that trade on the exchange all day.
  2. Large investors keep the price close to the holdings' value by creating or redeeming blocks of shares.
  3. The ongoing charge, typically 0.05 to 0.3 percent a year, is taken from the fund's assets.
  4. Dividends from the companies are paid out or reinvested, depending on the share class.

The honest pros and cons

For

  • The cheapest way to own hundreds or thousands of companies at once.
  • No manager risk: you get the market's return minus a tiny fee.
  • Trades any time the exchange is open, with a small spread.
  • Ideal for regular monthly investing.

Against

  • Falls as hard as the market it copies; a 30 to 50 percent drawdown is normal once a decade.
  • Which index matters: a home-country index is far less spread than a world one.
  • Foreign-listed funds can bring currency risk and withholding tax.
  • Some ETFs use derivatives to copy the index; check it holds the real shares if that matters to you.

Getting it in South Africa

Stock index ETF available

The JSE lists local and offshore-tracking ETFs, and ETF-only platforms let you buy them inside a tax-free savings account with a monthly debit order. Offshore-tracking ETFs give rand-hedge exposure without using your foreign allowance. Unit trusts are the older alternative with higher fees.

  • Account type: Tax-free savings account (TFSA) (interest, dividends and gains inside are tax free; withdrawals do not restore the used allowance)
  • Account type: Retirement annuity (RA) (contributions are deductible up to 27.5 percent of income within an annual cap; growth is tax free; access from 55 with two thirds forced into an income product)
  • Account type: Discretionary investment account (interest is taxed as income above an annual exemption, dividends carry a 20 percent withholding, and 40 percent of a capital gain is added to income)
  • Your protection: ETF units are held at Strate in your name, so they remain yours if the broker fails; no scheme covers market losses (source, checked 2026-09-17)
  • Tax here: inside a TFSA nothing is taxed; outside, dividends carry 20 percent withholding and 40 percent of a gain is added to income above the annual exclusion (source, checked 2026-09-17)

How to start

  1. Open a tax-free savings account at an ETF platform or your bank.
  2. Choose a world index ETF or a local top 40 tracker, whichever fits your plan.
  3. Set a monthly debit order and stay under the annual TFSA limit.

Wherever you are

  1. Pick the index first: world or global funds spread furthest; single-country funds bet on one economy.
  2. Compare the ongoing charge and the fund's size; large, cheap and physically backed is the usual choice.
  3. Buy through your broker inside a tax shelter, set up a monthly purchase, and stop checking the price.

Getting it from another country

Via United States allowed· available there

Use the single discretionary allowance through your bank and a broker's offshore account, or buy a JSE-listed feeder ETF in rand without using the allowance at all.

What you gain

  • A far bigger menu than the JSE and cheap US-listed index funds.
  • Rand-hedge exposure, which many South Africans want.
  • JSE-listed feeder ETFs give the same exposure in rand without paperwork.

What you give up

  • Currency risk cuts both ways when the rand strengthens.
  • The 15 percent US withholding tax on dividends, credited against local tax.
  • Amounts above 1 million rand a year need a tax clearance from SARS.
  • Tax: US dividends carry 15 percent withholding under the treaty; gains are taxed in South Africa with 40 percent of the gain added to income (source, checked 2026-09-17)

Currency reality check

The same ZAR 1,000 left for 10 years, at each country's savings rate:

Kept in ZAR at about 6.3% a year

ZAR 1,847

Sent to USD at about 2.5% a year, the account would show

USD 94 the tempting number

Brought back to ZAR after the exchange rate moved 22.4%

ZAR 1,563 what you can actually spend

Before tax, before fees, and before the risk that the exchange rate does something quite different next time. A higher rate abroad is only a higher return once it has survived the conversion back.
