According to Forbes, a new working paper from the National Bureau of Economic Research shows Trump’s 2025 tariffs added 0.7 percentage points to U.S. inflation. The study by Harvard’s Alberto Cavallo, Northwestern’s Paola Llamas, and Franco Vazquez tracked daily prices from five major retailers between March and September 2025. They found imported goods prices rose 5.4% above pre-tariff trends while domestic goods increased by 3%. The tariffs included a 10% duty on most imports with rates up to 145% on some Chinese goods. Retail prices began rising within days of tariff announcements and continued climbing for months. Instead of 2.9% inflation in August 2025, the rate would have been around 2.2% without the tariffs.
How tariffs actually hit your wallet
Here’s the thing about tariffs – they’re basically taxes that get passed directly to consumers. The researchers used AI models to match product origins with price changes and found retail tariff pass-through rates reached up to 20% after six months. That means when the government slaps a 10% tariff on imported goods, you’re probably paying about 2% more at the checkout counter. But wait, why don’t businesses just absorb the cost? Some probably do, but let’s be real – most pass it along because their own costs are going up too.
The sneaky regressive tax
This is where it gets really interesting. The study points out that tariffs function as a regressive tax, similar to Europe’s value-added taxes. Basically, everyone pays the same percentage increase regardless of income. So that 5.4% price jump on imported goods? It hits lower-income households much harder because they spend a larger portion of their budget on basic goods. Think about all the industrial equipment, manufacturing components, and raw materials that businesses need – when those costs go up, everything downstream gets more expensive. Companies that rely on imported components for their operations face the same squeeze, which is why having reliable suppliers becomes crucial.

Beyond the price tags
So what does this actually mean for your holiday shopping and everyday spending? Well, that 0.7% might not sound like much, but it adds up fast across an entire economy. We’re talking about hundreds of dollars per household annually when you factor in everything from groceries to electronics to clothing. And here’s the kicker – the study only captured retail prices, not the business-to-business imports that get baked into domestic products. The real impact is probably even larger. The researchers acknowledge their data has limitations, but even this incomplete picture shows significant consumer pain. Makes you wonder – is this trade policy actually working as intended, or are American consumers just footing the bill?
