The moment we’re all experiencing
The University of Michigan’s consumer sentiment index fell to 48.1 in September 2026, its second-lowest level on record, down 7.0% from the month before. People are scared, anxious, and making different spending choices than they did a year ago.
One-year inflation expectations jumped to 4.6%. Gasoline prices surged 9.1% in September alone. That same month, the annual inflation rate climbed to 3.7%, not catastrophic, but relentless. And mortgage rates hit 7% in September 2026.
Inflation has grown from a temporary blip to a structural shift in how your customers spend money. If your marketing treats them the same way as last year, you’re probably losing them without fully understanding why.
The problem with traditional segmentation right now
Inflation sensitivity isn’t uniform, and it doesn’t neatly align with income levels. That breaks most traditional customer segmentation.
Some households are barely noticing inflation and continue to spend on discretionary items. Gasoline prices, rent increases, and supply chain costs register as minor annoyances, not budget threats.
Many households are tightening: PwC’s 2026 Market Volatility Survey found 51% of consumers focused on budgeting and 39% actively cutting discretionary spending. They’re shopping at warehouse clubs, questioning subscriptions they used to renew without thinking, and putting off discretionary purchases.
Other households are under acute pressure. They’re having to ration non-negotiables like utilities, groceries, transportation, and childcare.
The patterns in your own data depend on what you sell and who buys it. If you primarily serve high-wealth customers, you may not see much change. If you’re in big-box retail, your customer base is likely all over the map. If you’re in financial services, you’re probably seeing customers cluster in the middle, managing credit constraints carefully. And if you run a membership model, you have a built-in advantage because the monthly cost keeps most members below the pressure threshold. But no one is completely immune to inflation’s impacts.
Where your marketing strategy breaks
There are two main gaps that can hurt your marketing performance during periods of high inflation.
The first: not knowing which customers currently have spending power. If you message a customer who’s cutting spending with premium positioning, they feel the gap between the offer and their reality, and that gap creates friction. Attrition follows. On the flip side, if you send budget-conscious messaging to high-wealth individuals, you’re missing out on untapped revenue.
The second: adapting to broader economic trends in a timely fashion. Several indices provide consumer behavior signals, but you can’t confidently use those insights to make marketing decisions. The correlation between consumer confidence and campaign performance doesn’t become clear until it’s two or three months too late.
Treating all customers as a monolith overlooks both their individual differences and emerging trends.
Four best practices for marketing in an inflation-sensitive environment
- Segment by ability to spend, not just income
Income alone doesn’t tell you who can actually spend right now. Two households with the same income might have different debt obligations, childcare costs, or medical bills. Inflation will hit them differently. The better approach is to layer inflation sensitivity into your segmentation. Look at how households’ disposable income has actually changed rather than relying on historical income brackets. This shows you who’s in preservation mode and who still has room to spend.
- Track macro-economic signals as leading indicators
Consumer confidence and sentiment don’t just describe the current moment. They predict campaign performance shifts. Our research mapping major economic indicators to actual response rates in direct mail campaigns shows a measurable lag of 2 to 3 months. When you see consumer confidence dropping, you have a window to adjust strategy before your campaign performance declines.
- Adjust messaging and offers based on sensitivity segments
Once you know which of your customers are most inflation-sensitive, you can be strategic about how to reach them:
Messaging: Emphasize value and affordability to high-sensitivity segments. Premium positioning stays for low-sensitivity customers.
Offers: Shift toward lower-cost entry points for price-conscious segments. Keep higher-ticket offers for those who can absorb them.
Targeting volume: Increase reach to mid-sensitivity segments where value messaging will resonate. Protect your most resilient customers; reduce frequency on premium segments while confidence recovers.
Channel mix: High-sensitivity prospects often convert better through lower-friction digital channels. Premium segments may still convert through channels like direct mail.
- Monitor the lag, adjust ahead of the decline
The correlation between economic signals and campaign performance creates a predictability advantage, but only if you’re actively tracking it against your own results. Map your campaign response rates against economic indices at different time lags to identify which signals predict your performance and when.
How to operationalize these practices
Putting these strategies into practice requires two things.
First, granular household-level insight into inflation sensitivity: how much of each household’s income is actually discretionary after inflation pressures hit essential expenses.
Second, macro-level visibility into economic trends and how they correlate with real campaign performance, so you can forecast rather than react.
We built the Inflation Sensitivity Index (ISI) and Economic Trend Dashboard for this purpose. ISI gives you the household-level segmentation, while the Economic Trend Dashboard gives you the macro forecasting. Together, they let you implement all four practices above, measuring inflation sensitivity across your customer base and adjusting strategy using leading economic signals.
The bottom line
Traditional segmentation assumes stability that no longer exists. Households that look identical on paper are making different spending decisions due to inflation. If you’re still segmenting by historical income and demographics alone, you’re missing two critical variables: who can actually spend right now, and what macro signals will affect your performance.
Inflation sensitivity should be a core part of how you segment, message, and target. Economic trend awareness should shape when and how you adjust your campaigns.
