Stocks Slump After Trump Threatens to Hit Iran Hard: July 29, 2026 — 2026-07-29
What moved & why: Escalating US-Iran tensions and Trump's threat of military action drove a broad equity selloff on Fed Day. Rising oil prices and Treasury yields triggered by geopolitical risk undermined cyclical stocks and prevented them from offsetting persistent weakness in AI-heavy tech.
Cross-asset:
- Equities: Nasdaq 100 down 11% from all-time highs; Dow Jones Industrial and Russell 2000 pressured by elevated fuel costs and higher interest expenses; 9 of 11 major sectors declining; energy and consumer staples bucking the decline; put option premiums rising on defensive demand.
- Rates/Treasuries: Treasury yields surging amid geopolitical tensions and oil price spikes.
- Dollar: Stronger greenback contributing to broad commodity retreat.
- Oil & commodities: Crude and natural gas advancing; other commodities retreating broadly due to risk-off sentiment and stronger dollar.
- Crypto: Bitcoin advancing; Ethereum declining; bifurcated performance.
Econ / Fed angle: Fed Chair Warsh faces pressure to either hike rates or reaffirm hawkish inflation commitment to prevent elevated fuel costs from spreading into core inflation. A hawkish stance risks worsening volatility. Australia's CPI eased to 3.8% y/y (from 4.0%) but remains above RBA's 2–3% target; Governor Bullock signaled additional rate hikes remain an option. UK mortgage volumes ticked up to 58,200 (from 57,100) on temporary rate relief but remain depressed versus the six-month average of 61,400.
