What Budget Constraints Reveal About Marketing Effectiveness
As consumer discretionary spending contracts, new research is forcing a re-examination of which marketing investments actually justify their cost.

Marketing organisations are entering a period in which growth in recommended spending categories coincides with a documented contraction in consumer discretionary spending. Deloitte Digital's 2026 Marketing Trends report notes that a significant share of consumers report cutting back on discretionary categories such as personal and home care, even as marketers are advised to expand investment in AI-native operations, retail media and creator partnerships.
This tension raises a methodological question that much current trend commentary does not fully address: how should organisations prioritise among competing recommended investments when overall budgets are not expanding at the same rate.
Retail media offers a useful case study. Industry analysis from Jan Kelley's 2026 marketing outlook describes retail media as a channel experiencing rapid growth, offering direct access to high-intent audiences and rich first-party data. However, the same analysis identifies fragmentation as the primary barrier to performance, cautioning that success depends on selectivity, aligning to category and geographic relevance, rather than broad participation across networks.
This pattern, in which a channel's aggregate promise diverges from its return at the level of an individual organisation, recurs across several of the trends currently dominating marketing commentary. Generative AI tools, for instance, have measurably lowered the cost of content production. Jan Kelley's research notes that AI-enabled video tools have removed longstanding production barriers, allowing small teams to create content that rivals larger studio output. Yet the same source cautions that production value alone can no longer serve as a competitive advantage, since the barrier it once represented has been largely eliminated for competitors as well.
Deloitte's research further finds that only a fraction of brand interactions are perceived by consumers as genuinely personalised, despite widespread investment in personalisation technology, suggesting a persistent gap between marketing effort and perceived customer value.
Taken together, this research suggests that effectiveness, rather than adoption speed, is likely to be the defining metric of marketing performance in a constrained spending environment. Organisations evaluating where to allocate limited resources may benefit from prioritising channels and tactics with demonstrable, attributable return over those simply identified as emerging or fashionable. In a period where consumer spending is contracting, the marginal value of any single marketing investment deserves closer scrutiny than industry-wide trend adoption alone can provide.
