US Markets Open Lower as Iran Escalation Returns — S&P 500 -0.1% from ATH; Brent $115/bbl as 'Project Freedom' Begins and Disputed Missile Incident Reported
US financial markets opened the week cautiously on Monday, May 4, 2026, retreating from last week's record highs as Iran war escalation risks resurfaced with the launch of 'Project Freedom' and contradictory reports of a possible military incident near the Strait of Hormuz. **Market performance (early May 4 trading):** - **S&P 500:** ~7,255 (−0.13% / approximately −10 points from close of 7,264 ATH on May 1) - **Dow Jones Industrial Average:** −0.36% (~−181 points) - **Nasdaq Composite:** +0.07% (~+20 points) — technology sector resilience amid tech earnings momentum - **WTI crude:** **$103.42/barrel** (+$1.48 from prior close) - **Brent crude:** **$115.01/barrel** (+$3.81 from prior close) — highest since the Iran war began **Disputed military incident:** Iran's Fars News Agency reported that two Iranian missiles struck a US warship near Jask Island (eastern Strait of Hormuz approach). The US Navy and Pentagon denied any warship was struck, confirming two US-flagged commercial vessels transited the Strait under Project Freedom escort without incident. Iran's IRGC released a map claiming control over Strait transit traffic and demanding 'toll payments' from commercial vessels not aligned with Iran's ceasefire terms. **Hormuz transit update:** The US Navy confirmed that Project Freedom's first day (May 4) resulted in at least two successful merchant vessel transits — the first commercial crossings in over a week — but the strategic situation remains highly volatile. **Recession probability impact:** Goldman Sachs maintained its 12-month US recession probability at ~25%; JPMorgan at ~30%; Moody's Analytics at ~42%. The Iran escalation-vs-ceasefire uncertainty remains the primary swing factor. If Project Freedom successfully normalizes Hormuz shipping within 2-4 weeks, recession probabilities could fall materially (Goldman has signaled a reduction to ~15-18% in that scenario). If Iran-US direct confrontation occurs, JPMorgan estimated recession probability spikes to 60%+. **Upcoming macro calendar (next 2 weeks):** - **May 5:** Section 301 trade investigation public hearing (15 countries including EU, China, Japan) - **May 5:** 25% EU auto tariffs take effect (Trump's May 1 announcement) - **May 7:** ADP National Employment Report (April 2026 private payrolls) - **May 8:** BLS April 2026 Nonfarm Payrolls (consensus: ~75-100K given Feb's -92K) - **May 11:** Kevin Warsh Senate floor confirmation vote (expected ~92% probability) - **May 14-15:** Trump-Xi Beijing summit (tariff de-escalation pathway) - **May 15:** Jerome Powell's final day as Federal Reserve Chair
