President Donald Trump Claims, "We Don't Have Inflation, and Tariffs Don't Cause Inflation," but a New Report Strongly Disagrees

New York Fed economists estimate that tariffs added 2.9 percentage points to goods-price inflation by February 2026; without tariffs, goods prices would have fallen slightly. Overall CPI was up 3.7% year over year in September, while fuel oil rose 74.0% and gasoline 34.2%, with the article also citing the Iran war and Strait of Hormuz closure as sources of cost pressure. The article warns that persistent inflation could prompt more Fed rate hikes and weigh on an expensive, AI-driven market by raising borrowing costs and slowing AI infrastructure investment.

Analysis

The market risk is a policy-mix squeeze, not simply higher headline CPI: tariff-related input costs and energy disruption can lift nominal yields while reducing real household purchasing power. That combination pressures long-duration equity multiples and can also squeeze AI infrastructure returns if financing costs rise or power, equipment, and logistics costs outpace monetization. The exposure is concentrated in expensive growth and capex-dependent segments; broad index performance may obscure that dispersion. Domestic producers are not automatic winners: reduced import competition can support pricing, but higher imported inputs can offset it.

Near term, positioning and the path of real yields matter more than the article’s inflation attribution. A sustained rise in real yields or inflation expectations could trigger multiple compression before earnings estimates adjust. Over 1–3 months, CPI/PCE, Fed communication, energy flows through the Strait of Hormuz, and any tariff changes are the key catalysts. Over 6–18 months, watch hyperscaler capex guidance and data-center project economics for evidence that higher costs are delaying or repricing investment.

Contrarian point: tariff pass-through estimates and a single inflation snapshot do not establish a durable inflation regime or guarantee a more hawkish Fed. Equity weakness may be overcalled if energy normalizes, core inflation cools, or AI spending remains funded. The thesis is falsified by a sustained decline in core inflation and real yields alongside unchanged AI capex plans. Verify current market pricing and the underlying inflation data before sizing a hedge.

Key Decisions for Investors

• Treat QQQ downside protection as a conditional hedge, not a directional short: consider a put spread only if implied volatility and premium are acceptable, with CPI/PCE and Fed communication as near-term review points. The thesis weakens if real yields fall and inflation measures continue to cool.
• Reduce concentrated, unhedged exposure to long-duration growth where valuation depends on distant cash flows; favor balance-sheet resilience and near-term cash generation over indiscriminate AI exposure. Reassess if hyperscaler guidance confirms capex plans and project returns are intact despite higher input costs.
• Avoid treating energy equities as a clean inflation hedge at current prices without checking how much disruption is already reflected. Monitor Hormuz shipping and crude prices; normalization would remove part of the hedge rationale and could reverse relative performance.
• Track real Treasury yields, inflation breakevens, core PCE/CPI, and hyperscaler capex commentary together. A rise in yields without deterioration in capex or earnings would argue against escalating the equity hedge; falling yields with resilient estimates would falsify the squeeze thesis.
