South African retailers head into 2026 on steadier ground than they have stood on for years — the rand has strengthened, the country has come off the FATF grey list, and GDP growth has moved above 1%. But the consumer underneath is still stretched. Unemployment remains north of 30%, three-month arrears accelerated sharply in the final quarter of 2025, and rejection rates on new credit applications sit around 70–80% as responsible lenders stay cautious. For a sector built on volume and thin margins, that combination — cautious optimism over a fragile consumer — is precisely where good analytics earns its keep.

The credit side is tightening at the same time. Amendments to the National Credit Regulations published in August 2025 sharpen affordability-assessment obligations, requiring credit providers to validate income and apply minimum expense norms rather than lean on assumptions — a direct constraint on how store-card and instalment books are underwritten. Buy-now-pay-later is moving toward the regulated framework through mandatory bureau reporting and affordability checks. For retailers extending credit, the era of light-touch underwriting is closing.

This is what makes retail a modelling-and-analytics sector rather than a reporting one. Demand forecasting decides inventory and markdown. Pricing and promotion analytics decide whether a margin point is won or given away. Store-card credit risk decides whether a book grows profitably or quietly accumulates losses under a rising arrears curve. Each of these is a question the headline figures obscure — and each is answerable with the right model and the right data behind it.
