• Oil prices surged 7.3% to $76.38 per barrel as insurance coverage was cancelled for ships through the Strait of Hormuz, effectively closing the critical shipping lane, while analysts estimate a sustained $10 oil increase could add 0.2-0.5% to CPI

Market Summary: Iran Conflict Triggers Sharp Selloff

Market Performance:

US markets opened sharply lower on March 3, 2026, with the Dow Jones plunging 1,244 points (-2.5%) to 47,650, the Nasdaq falling 2.7% to 22,126, and the S&P 500 dropping 2.5% to 6,711. Small-cap Russell 2000 declined 3.5%. These represent the lowest levels since November-December 2025 for major indices.

Key Catalyst:

Escalating US-Israeli military operations against Iran expanded beyond traditional concerns. Amazon Web Services reported damage to data centers in the region, with facilities in Bahrain also affected by nearby attacks. This shift in targeting infrastructure prompted analyst Kenny Polcari to note: "We're not talking about oil pipelines or shipping lanes anymore. We're talking about digital infrastructure."

Hardest Hit Sectors:

Technology stocks led losses, with Western Digital, Micron, Intel, Seagate, and ARM down over 5% in pre-market trading. Among Dow components, Caterpillar fell 4.6%, Sherwin-Williams dropped 3.6%, and Goldman Sachs declined 3.2%. Mag 7 stocks (Nvidia, Amazon, Alphabet, Tesla) fell approximately 2%.

Geopolitical Developments:

President Trump rejected Iran talks, stating "too late" via Truth Social. QatarEnergy halted LNG production after facility attacks. US embassies in Saudi Arabia and Kuwait temporarily closed, with Americans urged to depart immediately.

Commodity Impact:

WTI crude surged 7.3% to $76.38/barrel, highest since early 2025. Insurance cancellations for ships through Straits of Hormuz effectively closed the critical shipping lane.

Economic Implications:

Analysts warn a sustained $10 oil increase could add 0.2-0.5% to CPI and reduce GDP by 0.1-0.3%, with greater impact if crude reaches $100.
