Is offshore private lending a rand hedge?

Partly, and the word hedge is loosely used here. Holding capital in a hard currency reduces how much of your wealth depends on the rand, which is a diversification benefit for someone whose costs and other assets are all rand-based. But it is an open currency position, not a true hedge: a real hedge would use forward contracts, which cost money and remove the upside as well as the downside.

How does the rand affect an offshore return?

An offshore return has two parts. The first is the interest earned in the foreign currency, which is set by the arrangement. The second is what the exchange rate does over the same period. They combine multiplicatively, not by addition: a 14 percent return with the rand weakening 5 percent gives roughly 19.7 percent in rand terms, because 1.14 multiplied by 1.05 is 1.197.

What happens if the rand strengthens?

Your return in rand terms falls below the headline rate. Using the same arithmetic, a 14 percent return with the rand strengthening 5 percent gives about 8.3 percent in rand terms. The interest is unchanged; the currency simply works against you instead of for you. This has happened in South Africa more than once, including in the periods after 2002 and after 2016.

Has the rand always weakened against the dollar?

Over the long run it has depreciated, averaging roughly 5 to 6 percent a year against the US dollar over the three decades since 1994. But that average hides violent swings in both directions, including multi-year periods of significant rand strength. A long-run average is a description of the past, not a forecast.

When does the currency gain or loss actually happen?

Only when you convert back to rand. Until then the position is unrealised, and the rand value of your capital moves daily whether you look at it or not. This matters for timing: if you must convert on a specific date, you take whatever rate exists that day.

Who does offshore currency exposure suit?

Generally someone whose income, costs and other assets are already entirely rand-based, and who therefore has a concentration they may want to reduce. It suits less well anyone who will need the money converted back to rand on a fixed date, because that removes the ability to wait out an unfavourable rate.

Offshore Lending and the Rand: What Currency Does to Your Return

In short

An offshore return has two separate components. The interest is set by the arrangement and earned in the foreign currency. The currency movement is not set by anyone, and it can add to your return or subtract from it. They combine multiplicatively: a 14% return with the rand weakening 5% is about 19.7% in rand terms — and the same 14% with the rand strengthening 5% is about 8.3%.

Component 1

Interest — contractual

Component 2

Currency — uncertain

01 — The short version

The short version

When a South African places capital into an offshore lending arrangement, the headline number — say 14% a year — is earned in the foreign currency. Pounds, dollars or euros go in; pounds, dollars or euros come back, plus interest.

But you live in rands. Your expenses are in rands, and at some point most people convert back. So the number that actually matters to you isn't the 14%. It's the 14% combined with whatever the exchange rate did across the same period.

That second component is the one worth understanding properly, because it's the one nobody can promise you — and because it works in both directions.

02 — Two returns, not one

Two returns, not one

The single most useful thing you can do with an offshore return is stop treating it as one number.

The first component is contractual. The interest rate is defined by the lending arrangement — the term, the rate, the payment schedule. It doesn't depend on markets or sentiment. It depends on the borrowing being repaid under its terms, which is a credit question, not a currency one.

The second component is not contractual at all. Nobody sets the exchange rate for you. It's the aggregate of trade flows, interest-rate differentials, commodity prices, politics and global risk appetite — and it moves every day, in both directions, for reasons that have nothing to do with your arrangement.

Presenting these as a single blended figure is where explanations usually go wrong. It makes an uncertain component look as though it were promised. Keeping them separate is both more honest and, frankly, more useful: you can assess the credit risk and the currency exposure on their own terms, because they're genuinely different risks.

03 — How they combine

How the two combine

They don't add. They multiply — which is why the effect is larger than people expect.

If you earn 14% in dollars and the rand weakens 5% against the dollar over the same year, your rand return isn't 19%. It's:

The arithmetic

1.14 × 1.05 = 1.197 — a return of 19.7% in rand terms.

The extra 0.7 percentage points is the currency movement applying to your interest as well as your capital. Over multiple years, compounding widens that gap further.

And the same formula, unchanged, runs the other way. If the rand strengthens 5%, you get 1.14 × 0.95 = 1.083 — a return of 8.3% in rand terms. The interest didn't change. The currency simply moved against you.

04 — Worked both ways

A worked example, in both directions

Take R1 million placed offshore into an arrangement paying 14% a year, held for three years. The only thing that changes between these three scenarios is the currency.

If the rand…	Effective rand return p.a.	R1m after 3 years
Weakens 5% a year	≈ 19.7%	≈ R1,715,000
Stays flat	14.0%	≈ R1,482,000
Strengthens 5% a year	≈ 8.3%	≈ R1,270,000

The spread between the best and worst rows here is roughly R445,000 on the same R1 million, over the same period, from the same arrangement paying the same rate. That is the size of the currency component, and it's why it deserves to be discussed rather than folded into a headline.

Illustrative only. 5% is used as a round number in both directions to show the mechanism — it is not a forecast, and actual currency movement in any period may be larger, smaller, or in the opposite direction.

The currency isn't a bonus attached to the return. It's a second, independent variable that happens to be denominated in the same money.

05 — The long-run record

What the rand has actually done

Nobody can tell you where the rand is going. What can be said is what it has done, and that record is a matter of public data rather than opinion.

Since 1994 the rand has depreciated against the US dollar at an average of roughly 5–6% a year over three decades. That is a long and reasonably consistent direction of travel, and it's the reason the topic comes up in almost every conversation about offshore capital.

But an average is a summary, and this one hides a great deal. The rand has had multi-year periods of significant strength — notably the recovery after the 2001 crash, when it regained a large share of its value over the following two to three years, and again in the period after early 2016. Someone who converted at the wrong point in those cycles experienced the third row of the table above, not the first.

So the honest reading of the record is this: the long-run direction has favoured holding hard currency, and the short-run path has been violent enough that timing has mattered a great deal to anyone with a fixed date to convert on. Both statements are true at once, and only quoting the first is how people end up disappointed.

06 — Is it really a hedge?

Is offshore lending a "rand hedge"?

The phrase gets used loosely, and it's worth being precise, because precision here is genuinely useful rather than pedantic.

A true hedge is a position taken specifically to offset a risk — typically, in currency, a forward contract that fixes your exchange rate in advance. It costs money, and it removes the upside as thoroughly as the downside. That is not what's happening here.

What offshore exposure actually gives you is diversification away from a single currency. If your salary, your home, your retirement savings and your cash are all rand-denominated, then essentially your entire financial life is one concentrated bet on one currency. Placing part of your capital in a hard currency reduces that concentration. Colloquially people call it a rand hedge; technically it's an open currency position taken deliberately.

The distinction matters because an open position can move against you. Calling it a hedge implies protection in all conditions, and it doesn't provide that. What it provides is the position of not having everything in one place.

07 — Who it suits

Who this suits, and who it doesn't

It tends to suit someone whose financial life is already entirely rand-based and who is consciously reducing that concentration, with capital they can leave in place long enough to ride out an unfavourable rate rather than convert into one.

It suits less well anyone who must convert on a fixed date — school fees due in a particular year, a purchase already committed to. A hard deadline removes your only real defence against currency risk, which is the ability to wait.

It also doesn't suit someone who wouldn't be comfortable with the third row of that table. If a return of 8.3% instead of 19.7% would feel like something went wrong, then the currency exposure is larger than your appetite for it, and that's worth establishing before rather than after.

Two practical points sit alongside all this. Moving capital offshore happens within exchange-control allowances, so there's a process and a timeline. And because South African tax residents are taxed on worldwide income, the tax treatment of offshore interest — and of currency movements — is a question for a registered tax practitioner, not a website.

None of which is an argument against offshore exposure. It's an argument for going in with both components understood, rather than one.
