May 2026 data reveals a growing divergence between volume and value in the wholesale sector, with falling real demand offset primarily by surging fuel prices.
Wholesale trade sales plunged significantly in real terms this May, even as nominal figures reflected modest top-line growth. The contrasting results highlight the ongoing pressure inflation is exerting on overall demand across key economic sectors.
Volume Takes a Sharp Hit
Measured in real terms at constant 2019 prices, Stats SA reported that wholesale trade sales dropped by 6.9% year-on-year in May 2026 compared to May 2025. On a month-on-month basis, the contraction was even steeper. Seasonally adjusted real wholesale sales plummeted 7.4% in May relative to April. This follows a smaller decline of 2.3% in April and a brief rebound of 6.4% recorded in March.
Despite the volatile monthly readings, the broader trend over the recent quarter remains marginally positive. In the three months ended May 2026, seasonally adjusted real wholesale sales managed a 2.0% increase compared to the preceding three-month period.
Nominal Growth Masked by Energy Sector Inflation
In nominal terms—measured at current prices—wholesale sales increased by 4.0% year-on-year in May 2026. However, this gain was heavily driven by price increases in specific commodities rather than broad-based growth.
Dealers in solid, liquid, and gaseous fuels and related products were the primary driver of nominal growth, surging 24.2% year-on-year and contributing 5.6 percentage points to the overall May result. On the downside, the agricultural sector experienced notable weakness, with sales from dealers in agricultural raw materials and livestock falling 14.3% year-on-year, shaving 1.0 percentage point off the total growth figure.
Looking at the longer view, nominal sales rose 8.2% in the three months ended May 2026 compared to the same period in 2025. The strongest contributors to this annual quarterly expansion were:
- Fuel and Energy Products: Up 24.0% year-on-year, adding 5.6 percentage points to total growth.
- Intermediate Products, Waste, and Scrap: Up 22.5% year-on-year, adding 1.1 percentage points.
The overall picture shows an economy where top-line wholesale revenues are being artificially buoyed by higher prices—particularly in energy and raw materials—while the actual volume of goods moving through supply chains continues to shrink.
