Highlighted row (1980) represents the largest cumulative inflation erosion in the dataset. Multiplier bars scaled to 1980 maximum (36.14×). CPI index: December 2024 = 100.

South Africa's long inflation history reflects the compounding cost of political and economic instability: the combination of negative real interest rates during the 1980 gold boom, apartheid-era capital controls, and the 1985 Debt Standstill created conditions in which the purchasing power of a rand fell to less than 3 cents in today's money. But the structural turn under SARB Governor Stals — enforcing positive real rates through the 1990s — measurably slowed the erosion, cutting the multiplier from 36× in 1980 to 5.3× by September 1995. The transition to democracy therefore coincided with, and arguably reinforced, South Africa's first sustained period of monetary discipline — a stabilisation that the data shows clearly in the decelerating adjustment multipliers of the post-1990 period.
