Tariff effects unfold through several linked channels and should be analyzed in parallel. The importing company pays the tariff, but the ultimate burden may shift through lower exporter prices, reduced corporate margins, higher consumer prices, or some combination. Inventory accumulated before implementation can temporarily hide these effects by preserving a lower cost basis. Once inventory runs down, attempted price increases may cause consumers to reduce spending or switch products, creating demand destruction. If companies cannot pass through costs, weaker margins may lead to slower hiring or layoffs, feeding back into consumption and growth. The method therefore combines category-level inflation, inventory, spending, substitution, margins, and labor data. Its output is a dynamic assessment of the total economic impact rather than a one-dimensional inflation forecast.
Origin
Sonders uses this model to explain why the 2025 tariff process must be evaluated beyond headline CPI changes. Extracted from Masters in Business.
Core principles
- 01The importer pays the tariff initially.
- 02Inventory can delay the visible impact without eliminating it.
- 03Costs can be absorbed by exporters, companies, or consumers.
- 04Higher prices can trigger demand destruction and substitution.
- 05Margin pressure can feed into hiring and employment.
- 06Inflation data alone cannot capture the full economic effect.
How to run it
- 1
Locate the initial payer
Identify the domestic company importing the affected product and the tariff rate applied at entry. Distinguish the legal payer from the party that may ultimately bear the cost.
Pro tip Map major suppliers and importing entities by product category.
Watch out Do not assume the targeted foreign government directly pays the tariff.
- 2
Measure the inventory buffer
Estimate how much low-cost inventory was accumulated before tariffs took effect. Use inventory duration to judge when pricing and margin effects may become visible.
Pro tip Compare inventory growth with normal seasonal patterns.
Watch out A delayed impact is not evidence that the tariff has no effect.
- 3
Track cost allocation
Assess whether exporters cut prices, companies accept lower margins, or consumers face higher prices. The burden can be divided across all three channels.
Pro tip Use earnings calls and gross-margin data alongside price indexes.
Watch out Company announcements about pricing may precede actual realized pass-through.
- 4
Measure consumer response
Separate tariff-affected spending categories and monitor volume declines, substitution, and delayed purchases. Evaluate demand as well as prices.
Pro tip Weekly spending data can reveal behavioral changes before quarterly GDP data.
Watch out Higher prices can coexist with weaker nominal or real demand.
- 5
Follow the feedback loop
Determine whether weaker demand and margins alter capital spending, hiring, or employment. Feed those changes back into the growth assessment.
Pro tip Watch labor indicators in the most exposed industries first.
Watch out The aggregate effect may exceed the tariff's direct share of GDP because second-order effects compound.
In the wild
A retailer imports extra inventory before a tariff begins, delaying price increases for several months. When the low-cost stock is exhausted, it raises prices selectively, sees consumers switch to cheaper alternatives, and absorbs the remaining cost through lower margins.
→ The analysis identifies delayed inflation, demand destruction, and margin pressure rather than concluding that the tariff had no impact.
A manufacturer cannot fully pass tariff costs to price-sensitive customers. Falling margins lead management to pause hiring and reduce overtime, which weakens household income and local spending.
→ The framework captures a second-order labor feedback that a goods-inflation estimate would miss.
Common mistakes
Watching CPI alone
Inflation measures show price changes but can miss lost sales, substitution, margin compression, and labor effects.
Confusing payer and burden
The importer pays at customs, while the eventual economic burden may be shared among exporters, companies, and consumers.
Ignoring inventory timing
Pre-tariff stockpiling can postpone visible effects and create a false impression that companies are unaffected.
Is it for you?
Best for
It is best for macro investors, business planners, and analysts evaluating the evolving effects of trade policy.
Not ideal for
It is not suitable for estimating a company's exact tariff exposure without detailed supply-chain and customs data.
From the transcript
“tariffs are paid by the US company importing the goods, are not paid by the targeted country.”
“But what we're also starting to see is demand destruction and switching on the part of consumers.”
“So I think we have to analyze the impact of tariffs in a parallel fashion, not just gauging what the inflation impact is.”
