Introduction
"What trends are you following in consumer?" invites a list, and lists are where most answers go wrong. A candidate who names five themes in thirty seconds has shown that they read headlines. A candidate who takes one theme from what is changing to how it shows up in the numbers to which clients it creates work for has shown how a coverage banker thinks.
The question also tells the interviewer how current you are. Consumer trends move quickly, so a theme that was the story two years ago may already be priced in or reversed. This article covers how to pick a theme, how to back it with metrics and deals, how to link it to banking work and how to handle the pushback that follows.
Picking a Theme
A good theme is measurable, has deals attached to it and is one you have a view on. The best candidates for an interview are trends that a client's management team would be discussing on its earnings call.
| Theme | What to measure | Where it leads for bankers |
|---|---|---|
| GLP-1 drugs and food demand | Volume in snacks, sweets and sugary drinks among user households | Portfolio reviews, sales of exposed brands, purchases of protein and better-for-you brands |
| Store brands and trade-down | Unit and dollar share of store brands, price gaps | Retailer sourcing, national brands' pricing and promotion strategy |
| Restaurant value wars | Guest counts versus average check, franchisee margins | Refranchising, franchisee consolidation, valuation of franchisors |
| Tariffs and sourcing | Gross margin, landed cost, refunds of struck-down duties | Diligence on country of origin, purchase price adjustments |
| The luxury reset | Customer counts, price versus volume, Chinese demand | Brand turnarounds, family owners considering sales |
Choose one or two themes and go deep rather than covering all of them. The latest data on each sits in this guide's Market Intelligence section, from the value-seeking consumer to GLP-1 drugs, food policy and changing food demand.
- Trade-Down
A shift by consumers to cheaper alternatives within a category, such as from a national brand to a store brand, from casual dining to fast food, or from a department store to an off-price retailer. Trade-down shows up as stronger unit growth for cheaper options and weaker volume or mix for premium ones.
Keeping it current
Themes age quickly. Before an interview, check the latest quarter of results for the companies most exposed to your theme and look for the newest data release behind it. Earnings calls are the best source: if management teams keep raising a topic and analysts keep asking about it, it is a live theme. If the newest data point you can cite is more than a year old, the interviewer may know more recent numbers than you do, so either update the theme or choose another.
- Secular vs Cyclical Trend
A secular trend is a long-term shift driven by structural change, such as new technology, demographics or regulation, that persists through economic cycles. A cyclical trend rises and falls with the economy. Distinguishing the two is central to a trend answer, because it determines whether a change in demand should be valued as permanent or temporary.
Backing It With Evidence
A theme becomes an answer when you can attach a number and a company to it. The number shows the trend is real; the company shows you know where it matters.
Metrics
Use the metric a banker would use. For trade-down, that is store brands' share of units and dollars; the Private Label Manufacturers Association (PLMA) argues that unit share is the best measure of consumer choice, because dollar figures also move with national brands' pricing. Store brands reached a record 23.8% unit share in the six months to 14 June 2026, with unit sales up 0.2% while national brands fell 0.5%, according to Mass Market Retailers' report of PLMA and Circana data. The same report noted that store brands' dollar share momentum had softened, which is exactly the kind of nuance that makes an answer credible. How these data sources work is covered in consumer data: scanner, panel, card and foot traffic.
Deals and company results
Then connect the theme to a company or deal. For GLP-1 drugs, Circana estimated that 23% of US households had at least one user, according to Prepared Foods' report on Circana's research, and Hershey's purchase of the better-for-you snack brand LesserEvil, completed in November 2025, shows a confectionery group buying into a category that fits the new pattern. For the restaurant value wars, McDonald's results make the point: its US comparable sales rose 0.8% in the second quarter of 2026, driven by higher average check while guest counts fell, a sign that discounting had not yet won back the visits it was designed to recover.
Linking It to What Bankers Would Pitch
The final step is the one interviewers remember. Every trend creates winners and losers, and both are clients. Winners raise capital, buy competitors or list; losers sell non-core businesses, cut costs or look for a partner.
Turning a theme into a client idea
Ask three questions of any trend. Who benefits and needs capital or acquisitions to grow faster? Who is exposed and may need to sell, split or refinance? Who would buy the assets that come up for sale? For the restaurant value wars, the answers might be franchisors with strong unit economics that can keep funding value menus, franchisees under margin pressure who may sell restaurants, and larger franchisee groups or sponsors that could consolidate them. For tariffs, they might be importers with flexible sourcing that gain share, importers with concentrated sourcing that face margin pressure, and buyers who now ask detailed questions about country of origin in every process, as covered in tariffs, refunds and the consumer supply chain.
The same three questions can be run across every theme in the table above. Preparing the answers in advance means that whichever theme the interviewer picks up, you can move straight to the client.
| Theme | Who may need capital or acquisitions | Who may sell or restructure | Who may buy |
|---|---|---|---|
| GLP-1 drugs | Protein, fresh and portion-controlled brands | Snack and sweets portfolios with exposed brands | Large food groups and specialist sponsors |
| Store brands | Private-label manufacturers serving growing retailers | National brands losing share in commodity categories | Sponsors and manufacturers consolidating suppliers |
| Restaurant value wars | Franchisors with strong unit economics | Franchisees under margin pressure | Larger franchisee groups and sponsors |
| The luxury reset | Houses still growing customer numbers | Brands in turnaround, family owners | Luxury groups with patient capital |
Ending on a pitch does not require inside knowledge. A sentence such as which type of company you would call, and what you would suggest it consider, is enough to show the interviewer that you think about trends as a source of mandates.
Handling Pushback
Interviewers often test a trend answer by arguing the other side. Be ready for three kinds of challenge:
- Is it secular or cyclical? Trade-down may reverse when budgets recover; GLP-1 adoption may not. Say which you think it is and why.
- What data cuts against it? For the split between affluent and stretched consumers, the Federal Reserve Bank of Minneapolis concluded in March 2026 that the available data do not tell a clear K-shaped story. Knowing the counter-evidence shows you have looked beyond the headline.
- What would change your view? Name the data point you would watch, such as store brands' dollar share, guest counts or GLP-1 discontinuation rates.
General advice on market and industry questions is in market and industry questions in IB interviews. For consumer, the strongest trend answers are short, current and specific: one theme, one number, one company and one idea a banker could take to a client.
