The Fed Just Put AI on Its List of Inflation Shocks, Next to Tariffs and Oil

• The Fed raised rates by a quarter-point in September 2026 for the first time since 2023, with further hikes dependent on whether inflation shocks from tariffs, oil, and AI chips prove temporary or persistent
• Micron Technology is capitalizing on the shortage with gross margins jumping to 87% from 45.7% year-over-year, having presold most of its 2027 high-bandwidth memory supply at significantly higher prices
• Daly noted that 'hyperscalers' (giant cloud companies) are not interest-rate sensitive since they pay from cash flow, meaning rate hikes may squeeze households and small businesses before cooling AI chip demand

Market Summary: Fed Identifies AI Chips as New Inflation Driver

Key Development

San Francisco Federal Reserve President Mary Daly has classified AI chip shortages as a persistent inflation shock, placing it alongside traditional concerns like tariffs and Middle East oil prices. This marks a significant policy shift, as Daly stated in June 2026 that AI was not driving inflation.

Monetary Policy Impact

The Fed raised rates by 0.25% on September 16, 2026, setting the target range at 3.75%-4.00%—the first increase since 2023. The 10-year Treasury yield reached 5.31% on October 5. Daly indicated further rate hikes may depend on whether these shocks fade, though she views AI chip demand as more persistent, stating "This is probably further out before we get relief."

Market Performance

Major indices closed lower on October 6, 2026: S&P 500 down 0.71%, Dow Jones down 1.14%, Nasdaq down 0.76%, and Russell 2000 down 1.32%.

Chip stocks showed mixed results:

• NVIDIA closed at $239.24, up 0.14% (market cap ~$5.78 trillion)
• Micron Technology fell 1.73% to $1,045.56, up 266.56% year-to-date

Company Fundamentals

Micron Technology emerges as the primary beneficiary. The company's gross margin surged to 87.0% from 45.7% year-over-year, with most calendar 2027 high-bandwidth memory (HBM) supply pre-sold at significantly higher prices. Micron holds $32 billion in customer commitments through 26 strategic agreements.

NVIDIA faces margin pressure, expecting gross margins to bottom at 71-72% in Q4 due to "extreme pricing conditions in memory." Management forecasts AI chip demand reaching $800 billion in 2026 and $1.3 trillion in 2027.

Outlook

Supply relief appears distant, with Micron's new Idaho and Japan facilities not expected to begin production until late 2028, potentially sustaining elevated pricing
