The Rise of the K-Shaped Consumer: Reshaping Retail Growth

Across global retail and CPG/FMCG markets, economic pressure is accelerating a growing divide in consumer behaviour. As affordability pressures intensify and spending priorities shift, organizations are increasingly confronting a more polarized consumer landscape, where shoppers are gravitating toward either value-driven purchasing or more selective, premium-focused spending. 

Insights from Advantage Group International’s Q1 2026 Business Leader Interview series, conducted with 50 C-suite retail and CPG/FMCG leaders across EMEA, LATAM, North America, and APAC, suggest this divergence is becoming one of the defining structural shifts reshaping retailer–supplier partnerships.

Business leaders increasingly view today’s consumer polarization as more than a temporary response to economic pressure. Instead, it reflects a broader shift in how consumers define value, requiring retailers and suppliers to rethink how they create growth together.

The Middle Market is Under Pressure 

The current retail landscape reflects a continued erosion of the traditional middle market, driven by sustained cost-of-living pressure and changing spending priorities. Consumers are becoming more selective in how and where they spend, forcing organizations to compete across increasingly divergent consumer segments rather than through broad middle-ground positioning.

Leaders increasingly describe a “K-shaped” market, where one-size-fits-all growth strategies are becoming more difficult to sustain. Retailers and suppliers alike are being challenged to rethink how they create value, prioritize innovation, and position brands across increasingly fragmented consumer expectations.

At the lower end of the market, value expectations are intensifying. Retailers and suppliers point to a growing shift away from traditional brand preference toward more value-driven purchasing behaviour, reinforcing promotion-led activity and accelerating private label expansion. For many consumers, purchasing decisions are becoming driven by affordability rather than established brand preference.

For retailer-supplier partnerships, this shift extends beyond pricing. It requires closer alignment on assortment, innovation, and promotional strategies to ensure investments are focused on the consumer segments with the greatest long-term growth potential. 

Premium Spending is Becoming More Selective 

While economic pressure continues to impact household budgets, premium consumers remain comparatively resilient. However, loyalty at the top of the market is becoming more conditional, with consumers placing greater importance on trusted quality, expertise, and differentiated value.

Leaders also point to a persistent “lipstick effect,” where consumers continue to prioritize smaller, accessible indulgences despite broader financial pressure. Rather than eliminating discretionary spending altogether, many consumers are becoming more deliberate about which purchases they continue to prioritize.

This divergence is reshaping category dynamics. In more functional categories, brand loyalty is weakening as consumers shift toward lower-cost alternatives. In contrast, more personal or health-focused categories are seeing a continued “flight to quality,” with shoppers increasing spend in search of trusted, science-backed, or premium solutions.

Precision Is Replacing Broad Positioning 

As consumer expectations continue to diverge, retailers and suppliers are undergoing pressure to deliver sharper propositions, more targeted innovation, and clearer differentiation across both ends of the market.

Leaders increasingly suggest organizations must act as “curators of value,” balancing affordability, quality, innovation, and trust with far greater precision than traditional mass-market strategies allowed.

For partnerships, this shift extends well beyond pricing. It is reshaping assortment strategy, category planning, promotional investment, innovation pipelines, and long-term growth priorities across the value chain.

The rise of the “K-shaped” consumer is not simply a temporary reaction to economic pressure. It reflects a broader structural shift in how consumers evaluate value, prioritize spending, and define trust across categories.

As the middle market continues to fragment, organizations that attempt to appeal to everyone risk becoming increasingly diluted in their positioning and execution. In contrast, those able to deliver sharper propositions, stronger differentiation, and more targeted value creation will likely be better positioned to compete as consumer expectations continue to diverge.

Consumer polarization is only one of several structural shifts reshaping retailer-supplier partnerships. AGI’s latest whitepaper, The Collaboration Equation: Unlocking Value in a High-Pressure Market, explores these broader market forces, including changing consumer behaviour, supply chain resilience, execution capability gaps, and the growing importance of transparency and joint value creation.
