Tariffs became a lasting shock
What happened
Tariff policy from last year is now a persistent modelling problem for firms, raising input costs, altering investment timing and complicating inflation dynamics rather than acting as a one‑off shock. Companies in autos and retail have reworked risk models, political tweaks are easing specific frictions (helping EU‑US trade talks), and new tariff moves — including a 100% levy on patented drugs and targeted exemptions — are adding uneven effects across sectors.

Why it matters
The administration signed new tariff actions this week that go beyond one-off duties: patented pharmaceuticals face a potential 100% levy, but companies that cut prices or build U.S. manufacturing can avoid or reduce the charge, with large firms getting 120 days and smaller firms 180 days before the top rate applies and new domestic plants required by January 2029 to qualify for exemptions. (whitehouse.gov) (cnbc.com) Companies in sectors that rely on global inputs — especially automakers and large retailers — have moved from treating last year’s tariffs as a temporary hit to restructuring sourcing, inventory and investment timelines, increasing onshoring plans and raising prices or safety stocks to protect margins. (kpmg.com) (cnbc.com) On the technical side, the policy raises the economy’s “effective tariff rate” — an aggregate measure of how much import costs have risen — which Yale’s Budget Lab estimated at about 10.6% in January 2026 and found tariff pass‑through into imported goods prices in many categories between roughly 46% and 115% depending on the product, meaning firms must re-estimate expected input-price paths rather than treat duties as a one-time shock. (budgetlab.yale.edu) That shift forces concrete changes to corporate models: forecasting systems that previously assumed stationary input-cost distributions now need regime‑switch logic (models that allow structural breaks and different parameter sets after a policy shift), procurement algorithms must simulate higher safety‑stock tradeoffs, and capital budgeting increasingly uses “real‑options” thinking — valuing the option to delay or scale investments when tariff policy is uncertain rather than relying solely on discounted cash‑flow rules. (thomsonreuters.com) (oliverwyman.com) Those modelling changes matter quantitatively: the Budget Lab estimated tariff collections roughly $214.7 billion above 2022–24 averages through early 2026 and found a modeled 13.5% average price increase on new vehicles under a 25% auto tariff scenario (about a $6,400 rise per vehicle), while the administration’s sector-specific carve-outs (for example, a 15% rate for EU pharma under last year’s Turnberry framework) mean the shock is uneven across industries and trading partners.
