South Africa’s fixed investment rate has fallen to 13.9% of GDP in 2025, down from 21.6% in 2008, and analysts warn the figure now functions less as a measure of growth capital than as a bare maintenance level for the economy’s existing stock of assets. The 7.7 percentage point decline, equal to 35.6% of the original rate, is the single most important number underpinning both the country’s economic trajectory and, by extension, its political stability.
The quarterly picture offers little comfort. The latest seasonally adjusted and annualised figure came in at 13.7% of GDP in the second quarter of 2026, an improvement of 0.5 percentage points on the 13.2% recorded in the first quarter, but still below the 14.0% of a year earlier. Measured against international peers, the level is very low. The broader trend since 2008 has been downward despite temporary recoveries to 18.6% in 2013, 14.9% in 2023 and a trough of 13.1% in 2021. Successive rebounds have failed to restore earlier levels, leaving the country devoting a substantially smaller share of output to fixed investment than it did seventeen years ago.
Frans Cronje told The Common Sense that at these levels “the number may still be called the investment rate but it is in practice a care and maintenance rate and means that almost nothing by way of serious investment is entering the economy”. For investors and market-watchers, the implication is stark: capital formation has stalled to the point where the economy is essentially running down its existing base rather than expanding it.
The growth consequences are set out in data tracking the investment rate against economic growth since 1994, which shows that South Africa needs to lift its investment rate to well over 20.0% of GDP to begin reaching emerging market average growth rates. A further dataset linking growth to employment numbers since 1994 underlines the stakes, since job creation follows the investment cycle.
Cronje argues the chain of cause and effect extends into politics. “What these charts start to demonstrate is the chain of cause and effect that shapes living standards in South Africa. We can take that chain further and link it to African National Congress (ANC) support, as support for that party has risen and fallen in the same broad patterns as we have seen in fixed investment, living standards, and jobs,” he said. Data comparing employment with ANC support in national elections since 1994 bears out the pattern. The latest polls from the South Africa’s Social Research Foundation and News24 place the ANC in the 30% region, some 40 percentage points below the near 70.0% it held at its 2004 peak, four years before investment reached its post-1994 high in 2008.
The governing party’s response has drawn criticism. Earlier this week ANC secretary-general Fikile Mbalula wrote in an opinion article, responding to concerns about the investment rate, that “we are willing to discuss how our rules can work better and attract more investment, but sector rules cannot be waived by diplomatic agreement, nor can they be imposed from Washington. The question is not whether foreign companies can operate in South Africa, they have and continue to do so successfully. The question is whether they are willing to do so as partners in our national project, rather than as extractors.”
Cronje was unconvinced. “Talking about policies and setting conditions for investors is not the way to go about things when you look at the data trendline on fixed investment of the past decade, and that the number is still falling. If South Africa were growing strongly, had a low unemployment rate, and the ANC were firmly in power, then one might understand such an approach. But those are not the facts as the party faces them,” he said. He added that “the abiding mystery of my career is why the ANC will not understand this relationship”, citing the party secretary-general’s comments on the conditions attached to permitting investment.
In his view, the blockage is not simply corruption. “In South Africa’s case, the investment blockage is not as simple as corruption but rather extends to an edifice of policy that is openly hostile to investment and creates an economic climate in which South Africa just does not cut it from a competitiveness perspective,” he said, noting that many corrupt countries nonetheless attract investment and grow strongly.
Meanwhile, The Common Sense has produced and recently updated a set of scenarios for the coming decade, assigning a 65.0% probability to a break-up of the union into competing enclaves, some among the world’s most dynamic emerging markets, a 15.0% probability to the ANC changing tack on investment policy, and a 20.0% probability to a long-term recession. Whether the investment rate can be lifted above the 20.0% threshold before those scenarios play out remains the open question for the decade ahead.
