Tariffs linked to US 3.8% inflation

U.S. consumer prices rose 3.8% in the 12 months through April, according to Bureau of Labor Statistics data released May 12. Canada’s inflation rate was 2.4% in March, according to Statistics Canada, whose April CPI release was scheduled for May 19. That gap has fueled a burst of social-media claims that tariffs are a main reason U.S. inflation is running hotter than Canada’s. The official data support only part of that argument. BLS said energy prices rose 17.9% in the year through April and food prices rose 3.2%, while core inflation, which excludes food and energy, was 2.8%. That means tariffs are part of the inflation debate, but not the only moving piece in the headline number. ### Where does the 3.8% U.S. inflation figure come from? The Bureau of Labor Statistics said on May 12 that the Consumer Price Index for All Urban Consumers increased 0.6% in April on a seasonally adjusted basis and 3.8% from a year earlier. BLS said the energy index accounted for more than 40% of the monthly increase, with shelter also rising 0.6%. Those details matter because they show the April acceleration was broad enough to extend beyond trade policy alone. BLS said the all-items index rose 3.8% after a 3.3% annual increase in March, while core CPI rose 2.8% year over year. ### Is the Canada comparison correct? Statistics Canada said Canada’s CPI rose 2.4% year over year in March 2026, up from 1.8% in February. The agency said higher energy prices, especially gasoline, drove the faster headline reading. The social comparison to “Canada at 2.4%” is therefore accurate if it refers to March, not necessarily to the same month as the U.S. (bls.gov) April reading. Statistics Canada’s survey page showed the April 2026 CPI release date as May 19, 2026, which means some online posts were comparing different reporting months.

CBP said importers must pay applicable duties, taxes and fees on shipments under $800 that previously could enter without payment. The White House later expanded that approach. (www23.statcan.gc.ca) A July 2025 presidential action suspended duty-free de minimis treatment for covered products from all countries, and a Federal Register notice said the change requires formal entry and duty collection for covered imports valued at $800 or less.

The Budget Lab at Yale estimated on May 12, 2025 that the 2025 tariff package would raise consumer prices 1.7% in the short run, assuming no Federal Reserve response. It also estimated the average effective U.S. tariff rate would remain 16.4%, the highest since 1937 even after consumption shifts. (whitehouse.gov) A later Budget Lab tracker said imported core goods and durable goods prices both rose 1.5% during 2025 through January 2026, and estimated tariff revenue had reached $214.7 billion above the 2022-2024 average as of February 2026. Those estimates do not prove tariffs explain all of the 3.8% CPI rate, but they do show economists measuring visible pass-through into consumer prices.

The “28%” figure in the social posts could not be verified from primary official data or a named company filing in the available reporting. A CNBC report, citing Project44, said U.S. imports from China fell 28% year over year in 2025, but that is a trade-volume measure, not a direct price increase on consumer goods. (budgetlab.yale.edu) Trade reporting does show manufacturers moving production around Asia. CNBC and the Financial Times both described companies using “China plus one” strategies and shifting activity to Southeast Asia, including Vietnam, to reduce tariff exposure. The next hard checkpoints are dated. Statistics Canada published its April 2026 CPI release on May 19, and the Bureau of Labor Statistics is due to publish the next U.S. (cnbc.com) CPI report on June 10, when investors and importers will get another read on whether tariff costs are still feeding through to consumer prices.
