S&P 500

Key insight

The S&P 500 is under dual pressure from a deepening semiconductor sell-off (SMH -9% on the week) triggered by Chinese AI competition and surging 30-year Treasury yields near 5.10% — the highest since pre-GFC 2008 — which together threaten to crack the index below the critical 7,400 round-number support.

The S&P 500 has pulled back ~1.9% from its July peak near 7,575, closing Friday July 17 at 7,457.69 and trading at 7,433.42 Monday morning — breaking below the key 7,460 short-term support shelf — amid a semiconductor rout and escalating U.S.-Iran geopolitical risk that is driving oil sharply higher.

Main risk

U.S.-Iran Military Escalation & Strait of Hormuz Disruption

U.S. strikes against Iran have entered a third consecutive night, with Trump claiming control of the Strait of Hormuz; any closure or sustained conflict could spike oil above $90 and crush risk appetite, threatening a swift S&P 500 breakdown below 7,300.
