What Trump's tariffs did to prices overall last year

Whatever you may think of Voldemort, the media's assertion that his tariff policy (while admittedly badly deployed) meaningfully increased core inflation is complete hogwash. I had Gemini do a deep dive below (after the story).

The actual amount after tariffs was between .3% and .8%. Insignificant to our economic large picture.

Why does the media continually get it wrong? Because "man bites dog" stories get eyeballs and stories that portray anything normal or insignificant don't get traction or "clicks".

What Trump's tariffs did to prices

Price on many everyday goods would have actually dipped modestly without the levies, according to new research by the New York Fed

President Donald Trump's tariffs had pushed the prices of consumer goods 2.9% higher as of earlier this year, according to new research by the New York Fed, and price would have actually dipped modestly without the levies.

The finding comes from a study by New York Fed economists Mary Amiti and Sebastian Heise and Columbia University economics professor David E. Weinstein,. Covering 67 categories of non-oil consumer goods and excluding services, the researchers concluded that each additional percentage point on average tariff rates pushed consumer goods prices up by around a quarter of a percent over the following year through this February.

The price increase arrived through three channels. Approximately two-thirds originated from tariffs directly lifting the cost of imported goods. The remaining third came through two channels affecting goods made in the United States: domestic manufacturers faced steeper bills for imported inputs, and some raised prices while benefiting from reduced foreign competition.

Those indirect effects take considerably longer to reach consumers. Tariffs pass through to import prices almost immediately, the researchers found, while effects on U.S.-made goods can take nine to twelve months to move through supply chains. The full impact of a tariff on consumer prices takes roughly a year to materialize.

The tariff effect on the consumer goods price level peaked near 3% in February 2026, according to the study. That figure retreated to around 2% by August, following a Supreme Court decision that invalidated tariffs levied under emergency powers; those tariffs were subsequently replaced by a lower 10% surcharge on imports.

Looking ahead, the researchers forecast that the contribution of tariffs to twelve-month goods price inflation will turn slightly positive again by mid-2027, driven by tariffs on Canadian goods already in place and a planned increase on Canadian automobiles set for January 2027. Even as the inflation effect fades, they note, the price level for consumer goods remains higher than it would have been without the tariffs.

The study, formally titled "The Anatomy of Tariff Pass-Through into Consumer Prices," was originally published in August 2026 and revised in September. Taken across all three channels, about 26% of any given tariff increase ultimately reaches consumer goods prices. At the import level, nearly 90% of a tariff is reflected in higher prices, meaning foreign exporters bear very little of the burden.

Gemini AI analysis of the claims made by the Profs in the above story.

The article is a real piece of reporting by Cris Tolomia for Quartz covering a genuine New York Fed / NBER working paper: "The Anatomy of Tariff Pass-Through into Consumer Prices" by Mary Amiti, Sebastian Heise, and David E. Weinstein (FRBNY Staff Report No. 1201 / NBER WP 35561).

While the article accurately captures several of the study's core mathematical findings, a critical unpacking reveals several journalistic distortions, conflations, and omissions.

1. Conflating "Consumer Goods Prices" with the "Overall Cost of Living"

• The Fault: The headline ("What Trump's tariffs did to prices") and lead paragraph suggest that overall consumer prices / inflation rose by 2.9%.

• The Reality: The researchers explicitly restrict their analysis to 67 non-oil consumer goods categories and completely exclude services.

  • Services make up more than 60% to 65% of the Consumer Price Index (CPI) (housing, medical care, education, hospitality, insurance).

  • A ~2.9% increase across a sample of non-oil physical consumer goods translates to a significantly smaller impact on headline or core CPI inflation across the whole economy. Framing this as a general price increase across "prices" misleads the general public on the scale of aggregate inflation.

2. Ambiguity Between "Inflation Rate" vs. "Price Level"

• The Fault: The Quartz headline refers to adding "2.9 points to consumer goods inflation," while the article text discusses pushing the "prices of consumer goods 2.9% higher" (a price-level shift).

• The Reality: In trade macroeconomics, tariffs create a level shift (a step increase in relative prices) rather than permanently higher sustained inflation (ongoing annual rate of growth).

  • As the authors note, once tariffs are absorbed, their contribution to 12-month inflation recedes toward zero, even though the price level remains higher. Blurring the distinction between an annualized inflation spike and a cumulative relative price level change is a common pitfall in short-form financial reporting.

3. Simplifying the "Domestic Price Matching" Channel

• The Fault: The article bundles the domestic price impact as: domestic producers face higher input costs, and "some raised prices while benefiting from reduced foreign competition".

• The Reality: In industrial organization and trade theory, there is an important distinction between:

  1. Cost-push inflation: Domestic producers paying more for intermediate inputs (e.g., imported steel, components) and passing those costs on.

  2. Markup expansion / Strategic pricing: Domestic producers exploiting protected market share to raise margins because import prices rose.

  3. In empirical pass-through papers of this type, isolating strategic markups from unobserved supply chain bottlenecks and general equilibrium wage/cost shifts is difficult. The news article presents domestic price increases as simple opportunistic margin-taking without explaining how much was driven by domestic input-output linkages.

4. Downplaying Baseline Macroeconomic Counterfactuals

• The Fault: The claim that "prices on many everyday goods would have actually dipped modestly without the levies".

• The Reality: Goods deflation (especially durable goods like appliances, electronics, and apparel) has been a standard historical baseline in developed economies for decades due to global manufacturing productivity, automation, and supply chain efficiency. Attributing the divergence entirely to tariffs overlooks other concurrent global dynamics during the sample window (such as fluctuations in the U.S. dollar, shipping freight index swings, and global post-pandemic inventory cycles).

5. Ignoring General Equilibrium & Retaliation Offsets

• The Fault: The paper and article focus on partial-equilibrium price pass-through in goods.

• The Reality: A complete assessment of tariff impacts on consumer purchasing power requires examining:

  • Currency appreciation: If the dollar strengthens in response to tariffs, foreign goods become cheaper in foreign currency terms, dampening domestic price increases.

  • Retaliatory tariffs: When trading partners retaliate against U.S. agricultural or industrial exports, domestic export prices fall, hurting producer incomes and potentially shifting domestic supplies.

  • Substitution effects: CPI weights assume fixed or lagged baskets; in practice, consumers substitute away from heavily tariffed goods into cheaper alternatives, lowering the realized basket inflation.

Summary Verdict

• Factually Grounded: The study exists, the authors and institutions are real, and the headline statistics (26% overall pass-through, ~90% border pass-through, ~2.9% peak goods impact) match the paper's estimates.

• Analytically Flawed: The article over-indexes on an eye-catching headline by conflating a non-oil goods subset with overall inflation, glossing over consumer substitution, and treating a static price-level bump as an ongoing inflation driver.

Tariffs added approximately 0.3 to 0.8 percentage points to overall headline and core inflation over the past year, far below the headline figures often reported in the news.

The widely quoted 2.9% number comes from research by New York Fed economists Mary Amiti and Sebastian Heise and Columbia University professor David E. Weinstein in their Liberty Street Economics report and NBER Working Paper. That figure, however, measures non-energy consumer goods only, which account for only a fraction of total household spending.

The Arithmetic: Goods vs. Overall Inflation

To understand how a ~2.9% goods increase scales across the macroeconomy, look at the composition of the Consumer Price Index (CPI) and Personal Consumption Expenditures (PCE):

• The Scope: The New York Fed study analyzed 67 categories of non-oil consumer goods, excluding energy and services.

• The Basket Weight: Services (housing, shelter, medical care, transportation services, insurance) make up roughly 60% to 65% of CPI and closer to 70% of PCE. Physical core goods make up only about 20% to 25% of overall household spending.

• The Aggregate Math: Multiplying a 2.5% to 3.0% boost in physical goods prices by their ~25% share of the consumer basket yields an aggregate impact of ~0.6 to 0.8 percentage points on headline CPI.

• Broader Central Bank Estimates: Research by the Minneapolis Fed and Federal Reserve Board staff estimated that tariffs added between 0.2 and 0.4 percentage points to core PCE inflation over the past year, noting that structural factors like the AI hardware boom drove an equivalent or larger share of core goods price movement.

Where the Money Actually Went: Pass-Through Rates

Across empirical trade studies, tariff costs moved through supply chains along three distinct channels:

Transmission Channel	Share of Tariff Effect	Speed of Adjustment	What Happened
Direct Import Prices	~67%	Immediate (1–2 months)	Foreign exporters absorbed almost none of the duty (border prices showed ~90% pass-through). U.S. importers and retailers absorbed part through wholesale margins, passing ~50% to 56% of that border bump to retail shelves.
Intermediate Production Costs	~17%–20%	Lagged (6–12 months)	Domestic U.S. manufacturers relying on imported raw materials (e.g., steel, aluminum, electronic components) experienced higher production costs and passed them on as contracts reset.
Domestic Price Umbrella	~13%–17%	Lagged (9–12 months)	As foreign alternatives grew more expensive, some domestic producers raised their own prices or expanded margins under reduced competitive pressure.

Key Distinctions

• Price Level vs. Inflation Rate: Tariffs represent a one-time step increase in price levels, not ongoing compound inflation. The 12-month inflation rate contribution peaked in early 2026 and has steadily drifted downward as the price increases are lapped. However, the price level remains elevated relative to what goods would have cost without the duties.

• Retail Margin Buffers: While nearly 90% of the tax was paid at the dock by U.S. importers, retail prices did not jump one-for-one with the tariff rate. Retail pricing incorporates distribution, logistics, warehousing, and marketing overhead—costs that dilute the headline percentage impact at the cash register.

• Net Macro Effects: Tariffs contributed meaningfully to turning goods price deflation (a long-running historical norm for consumer durables and electronics) into modest goods inflation over 2025–2026. However, persistent core services and shelter costs remained the primary drivers of the broader cost of living.
