The rand’s long-term decline: what history tells South African investors

South African rand banknotes and exchange rate chart

Since the rand was introduced in 1961, it has lost more than 98% of its purchasing power against the US dollar. This isn’t a failure — it’s a normal feature of emerging-market currencies.

Understanding this long-term trend helps explain why many South African portfolios include foreign assets and why the rand cost of global investments usually rises over time.

100 Years of Rand Depreciation

Even before the rand existed, the South African pound tracked a similar path. The pattern is clear: in real terms, the currency loses roughly 4–6% per year against major developed-market currencies over decades.

Main Drivers of the Trend

01

Higher local inflation

SA CPI has historically run 2–4% above developed markets

02

Commodity price cycles

Terms-of-trade shocks affect emerging-market currencies

03

Political & policy risk

Periodic risk premiums demanded by global investors

Why Offshore Assets Benefit

A global index that returns 6% in dollars will deliver roughly 11–12% in rands over the long run because of currency movement. This effect has been one of the biggest contributors to offshore returns for South Africans.

What History Teaches Us

The rand’s structural weakness is unlikely to reverse permanently. This reality — not speculation — is why diversification beyond the rand remains a core principle for most long-term South African investors.
