President Donald Trump Just Admonished the Fed for "Doing the Wrong Thing" on Interest Rates, but Ignores the 2 Biggest Inflation Catalysts

The Fed raised its federal-funds target range by 25bps to 3.75%-4.00%, prompting declines in the Dow, S&P 500 and Nasdaq. Persistent inflation—above the Fed's 2% target for 66 consecutive months in August—is attributed in the article to broad tariffs, the Iran war's energy-supply disruption, and AI hardware shortages that are boosting downstream prices. The inflation backdrop limits the scope for the rate cuts President Trump has advocated.

Analysis

The relevant transmission is not simply higher discount rates: a tariff- and energy-driven inflation mix compresses real household purchasing power while raising corporate input costs, leaving the Fed unable to ease into slowing growth. That is a stagflationary relative-value setup for the next 1-3 months: domestic, low-import-content businesses with contractual pricing should outperform consumer discretionary, transport, chemicals and smaller manufacturers that cannot fully pass through costs. The broad-index response may understate this dispersion because AI-heavy mega-cap earnings can offset weakness elsewhere.

NVDA and the HBM ecosystem retain near-term revenue and gross-margin protection if accelerator scarcity persists, but the market should distinguish supplier pricing power from end-customer economics. Hyperscaler capex is increasingly funded by debt and free cash flow rather than cheap capital; sustained high real rates raise the hurdle for incremental data-center projects and can move the AI risk from chip availability to utilization and customer ROI over 6-18 months. The key falsifier for the bullish semiconductor view is not another supply-tightness headline, but a cut in cloud capex guidance, falling lead times, or HBM contract-price normalization.

Consensus may be too linear in treating inflation pressure as unequivocally bullish for energy and AI infrastructure. A policy-induced demand slowdown would first hit cyclical oil demand and enterprise software consumption, while capital-intensive data-center operators face both power-cost and financing-cost pressure. Conversely, any credible de-escalation in energy disruption or tariff rollback would lower inflation breakevens quickly, drive a duration rally, and favor beaten-down rate-sensitive growth more than already premium-valued AI hardware.

Key Decisions for Investors

• Maintain a 1-3 month relative-value long NVDA / short DOW position: NVDA has near-term supply-constrained pricing and demand visibility, while DOW is exposed to energy/feedstock costs and global industrial demand. Size modestly given NVDA valuation risk; exit if NVDA reports material lead-time compression or hyperscaler capex guidance falls.
• Buy 3-6 month put spreads on XLY or maintain a long XLP / short XLY pair rather than shorting the S&P 500 outright. The intended payoff is from consumer-margin and real-income dispersion; invalidate on a sustained decline in core inflation and a clear Fed easing pivot.
• Do not add directional long exposure to data-center developers or highly levered infrastructure owners until financing assumptions are disclosed. Create an alert around hyperscaler quarterly capex guidance, AI-service revenue growth, and power-purchase costs; a capex cut would favor shorts in capital-intensive AI infrastructure over NVDA.
• For a disinflation hedge, own a small 6-12 month duration-risk reversal via long TLT calls funded with out-of-the-money puts, or use a defined-risk call spread. This protects the book if energy/tariff pressures reverse; abandon the hedge if inflation expectations re-accelerate and long-end yields break materially higher.
