Why everything with a chip got expensive — and where it leads

Chips alone won't cause a crisis. 2026 is risky because three shocks are stacked — AI outbidding everyone for memory, the Iran-war energy shock, and tariffs — while central banks raise rates.

The core idea

One coin, two sides

Click the coin to flip it

The money isn't disappearing — it's moving from people who buy devices to the companies that make chips and the shareholders of AI firms.

The catch: what would make gadgets cheap again (an AI slowdown and a memory glut) is exactly what would crash AI stocks. Relief for one side means pain for the other.

What's happening

Three shocks, stacked

Any one of these alone would be manageable. Together, while interest rates rise, they create real stagflation risk.

AI outbids everyone

  • Data-center spending > $700B this year
  • AI memory (HBM) uses ~3× the wafer per bit
  • DRAM + NAND up 300%+ vs a year ago
  • Relief only when new fabs ramp: late 2027–2028

Iran-war energy shock

  • War since 28 Feb; Hormuz mostly closed
  • Brent ~$105 a barrel
  • Qatar helium (30–38% of world supply) disrupted — chip fabs need it
  • US gasoline +27% vs a year ago

Tariffs & fragmentation

  • 25% US tariff on some advanced chips
  • 10–12.5% tariffs on ~60 economies since 24 July
  • US–China rare-earth truce expires Nov 2026
  • Goods trade growth: 4.6% to 1.9%
+ rates
Fed hiked on 16 Sept for the first time since 2023 (to 3.75–4%). ECB hiked to 2.5%. US 10-year borrowing cost ~5.17%, highest since 2007. Rate hikes can't make more DRAM or oil — they only cool demand elsewhere.

Fewer devices, higher prices

Industry revenue can hold up even as unit sales collapse — budget buyers and budget brands get pushed out.

Four ways this could go

My judgment, not a forecast. Pick a scenario to see what happens to each part of the economy.

Worst realistic combination: scenarios 2 and 3 at the same time — an AI market crash during an energy-driven inflation spike.

Bottom line

Off, not broken

The price system is routing scarce chips to the highest bidder: AI. Costs land on consumers, especially the lower half; gains land on chipmakers and shareholders. Chips alone mean pricier gadgets and slower progress, not a crisis. Real crisis risk comes from energy shock + high rates + AI-concentrated markets. Don't expect 2025 prices back soon — waiting for a crash is a bet on scenario 2.
