Key Findings

South Africa's Competition Commission has documented a substantial gap between declining farm-gate prices for staple crops and the prices consumers continue to pay at retail outlets, according to the Commission's March 2026 Cost of Living Report.

White Maize: A Case Study in Price Stickiness

The Commission found that white maize prices at the farm level fell sharply from R22.16 per unit in May 2025 to R14.49 by December 2025—a 35% decrease attributed to favorable harvest conditions (verified, high-confidence claim from Competition Commission March 2026 report).

Despite this significant input cost reduction, the verified data shows:

  • Maize meal manufacturers did not reduce retail prices, with some implementing increases
  • Retail profit margins on maize meal reached 37% in November 2025
  • The Commission has announced it will conduct a close investigation of the maize meal market
The Commission stated: "This is concerning given that maize meal is a staple food item for most low-income households" (direct quotation, verified).

Independent Price Monitoring Confirms Mixed Trends

The Pietermaritzburg Economic Justice and Dignity Group, in its March 2026 report, recorded the following verified price data:

Declining prices:

  • 30kg maize meal: R305.07 (12% decrease from R347.90 year-on-year)
  • 10kg rice: R129.92 (25% decrease)
  • Sugar beans: R183.54 (22% decrease)
  • Potatoes: 13% decrease
Rising prices:
  • 10kg frozen chicken portions: R436.75 (6% increase year-on-year)
The Commission noted that retailers increased chicken prices despite farm prices remaining stable at approximately R45. For eggs, farm prices dropped from R13.32 (June 2025) to R11.69 (November 2025), yet retail prices "hardly changed."

Commission Assessment

The Competition Commission has characterized retailer pricing behavior with the verified assessment that shops are "quick to raise prices but slow to drop them." The Commission explicitly links this pattern to disproportionate harm against poor households, who allocate the majority of their expenditure to food.

The investigation into maize meal market dynamics represents an active regulatory response to these documented pricing patterns.
