South Africans don't need quarterly reports to realize the cost-of-living crisis. They feel it till the end. The question is why our data systems are still catching up months after homes have adapted, and what are we losing in that delay.
South Africa's official consumer price index was projected to average 3.2% in 2025, the lowest rate in 21 years. On paper, this signals relief. In practice, this obscures the more disturbing signal.
When you look at what consumers are actually putting in their baskets, not just how prices are rising overall, but what households are choosing to buy or quietly leaving on the shelf, the picture becomes much less reassuring.
Families are not buying less as prices fall. They are buying less because they cannot afford to buy more.
That gap (between what the headline numbers say and what the behavior reveals) is the real story.
Blind spot in our economic lens
Traditional inflation metrics are structurally backward-looking. By the time CPI data is published, households have already made their own adjustments: switching brands, dividing purchases among cheaper stores, quietly removing items from the basket altogether.
The statistics confirm what families have already gone through.
The problem is complicated by where our data comes from and how often it is updated and shared. South Africa's formal retail sector accounts for approximately 57% of FMCG sales by value.
The remaining 43% flows through informal traders, township spaza shops and neighborhood convenience stores. Yet transactions in those environments are almost completely invisible to the datasets used to guide policy and business decisions.
This is not a minor data gap. Informal FMCG trade was valued at R207 billion by the end of 2024, and spaza shops overtook supermarket chains in 2025. We are making judgments about the consumer economy while being unaware of almost half of what South Africans actually spend.
What real-time data reveals
When you look at the entire retail landscape (formal and informal), the picture becomes quite clear. Consumers are splitting their purchases among multiple retailers given the price difference. Entire product categories are silently disappearing from baskets. Brand loyalty is eroding due to financial pressures. And these changes are happening not in quarters but in weeks.
The FNB/BER consumer confidence index fell to -13 in the third quarter of 2025, and a separate study found that 42% of South Africans are constantly worried about their finances, with 29% reporting that money stress is harming their mental health. These are not abstract economic signals. They are a population living under constant pressure, and our measurement systems are very slow to respond in time.
Fintech provides a realistic, real-time economic buffer
This is where the conversation needs to shift. Financial technology is often discussed in the context of convenience. Its more powerful, but rather underutilized, role is that of a real-time economic buffer.
South African consumers completed more than 118 card transactions per capita in 2025, with total card volume reaching R2.9tn. Data infrastructure is in place; What's missing is the will to use it as a tool for household resilience, not just business insight.
Retail-agnostic data systems used across formal and informal social sectors can detect financial stress as it occurs, not months after the fact. That real-time visibility creates an opportunity: Fintech platforms can return immediate value to consumers through micro-rewards, airtime, or digital incentives tied to everyday purchases, exactly when household budgets are under most pressure.
At scale, these small buffers matter a lot. In emerging markets, resilience is built on thin margins, and when those margins disappear, sensitivity to economic shocks increases rapidly.
South Africa cannot afford to miss this opportunity
South Africa has a rare combination of assets: a sophisticated fintech ecosystem, a highly diverse retail landscape, and widespread mobile adoption. This combination leads us to pioneering models and technological solutions where consumer data and financial value can truly interact in real-time.
This will help us bridge the gap between informal and formal retail: enabling faster, more targeted responses to consumers under economic stress.
The future of financial inclusion will not be built on lagging indicators. It will be built on a system that will see what is happening right now and take action on it. The data is already there, in every receipt, in every cart, every purchase silently removed from the shopping list.
We just need to start hearing it in real time.
