According to the Competition Commission‘s third Cost of Living Report, the price of water, electricity and government school fees has risen faster than the overall rise in consumer prices, a trend that hits both families and small-business owners.
Headline inflation measures the total increase in prices for all goods and services in an economy, including volatile categories like food and energy that can swing sharply from month to month. Over the past six years the headline figure has been about 36%, but the report says essential services have consistently outpaced that rate.
Transport costs have spiked this year, with diesel prices up more than 11%, adding another layer of pressure on household budgets and on businesses that rely on road freight.
Food prices present a mixed picture. The report notes that even when maize producer prices were rising, retail prices fell, suggesting retailers were absorbing some of the cost. Analyst Anthony Clark explains that food companies often lock in input costs three to six months ahead, so cheaper grain stocks take time to reach shelves. He warns that soft-commodity prices such as wheat, corn and soybean have jumped 30% to 40%, while fuel costs have surged about 70%, a combination that will likely lift food prices further in 2027.
What this means for small businesses
For an SME that runs a café, a construction firm or a retail shop, higher water and electricity bills directly cut into profit margins. The same applies to transport-dependent businesses that now pay more for diesel. When essential costs rise faster than overall inflation, cash-flow forecasts become tighter and the ability to invest in growth or staff can be compromised.
The Competition Commission concluded that South African households continue to face significant and persistent cost-of-living pressures, with the cumulative increase in essential goods and services eroding purchasing power. The same pressure is felt by small enterprises that serve those households, creating a feedback loop that can slow economic activity.
Why essential-service inflation hurts more than the headline number suggests
Headline inflation measures how prices for a broad, weighted basket of goods and services move on average, but that average obscures a critical distinction for lower- and middle-income households and small businesses specifically: essential services like water, electricity and transport are not optional line items that can be cut back when budgets tighten the way discretionary spending can, which means a below-average headline inflation figure can still coincide with a genuinely painful squeeze on disposable income if the specific costs that cannot be avoided are the ones rising fastest. That is precisely the gap the Competition Commission’s report is highlighting: the national inflation figure moderating does not automatically mean the pressure on ordinary households and SMEs is easing, if the categories of spending they have the least flexibility to reduce keep outpacing it.
The Competition Commission’s own Cost of Living Report series exists precisely to surface this kind of gap between the headline number and lived experience, since a national inflation figure is, by design, a weighted average across an entire population’s spending patterns, while any individual household or business’s actual cost pressure depends heavily on how much of their own budget is concentrated in whichever categories are currently rising fastest. For a small business owner watching margins tighten even as official inflation appears to be moderating, that distinction is not an academic one, it is often the exact explanation for why their own costs do not seem to match what the headline figure implies.
Transport is a particularly clear example of that dynamic in the commission’s own findings: an 11% jump in diesel prices does not stay contained to fuel budgets, it works its way into the delivered cost of almost everything a small business buys or sells, since road freight underpins the vast majority of goods movement in South Africa, which is exactly why a spike in one narrow input can end up widening cost pressure across an entire local economy rather than staying isolated to transport-dependent firms alone.
