Is U.S. Inflation Driven More by Tariffs Than Core Goods Prices?
Core argument: Core goods inflation runs 1 pp faster than pre-pandemic 2023–2024 levels, driving persistent price pressures beyond tariff impacts.
Prices for physical goods were rising faster than at any point outside of the post-pandemic reopening before the Iran War. While some of that can reasonably be attributed to tariffs, tariffs are not the only, or even the main explanation. First, core goods inflation was running about 1pp faster than pre-pandemic in both 2023 and 2024, with price declines starting to slow beginning in mid-2024. Second, much of the recent pick-up in core goods inflation is attributable to items that are explicitly exempted from tariffs, such as computer parts that are used in data centers. By contrast, important categories that have been subjected to large tariffs, such as motor vehicles and parts—both directly and via punitive tariffs on steel and aluminum—have experienced relatively little inflation. The PCE price index for “computer software and accessories” rose by 8% between February 2025 and February- 2026, whereas prices for “motor vehicles and parts” have been flat. The boom in demand for goods needed for AI development has dwarfed the impact of tariffs. [Further], inflation [for restaurants] and other services, such as dental visits, haircut and dry cleaning have all either remained persistently faster than before the pandemic or have accelerated in the past year. Tariffs cannot plausibly explain any of these moves.
