• Oil futures markets expect prices to decline to below $80 by September and under $75 by year-end despite current volatility, while energy stocks led Monday gains with 1-2% increases

Market Summary: Oil Prices Surge on U.S.-Iran Tensions

Key Developments:

U.S. crude oil prices jumped 4.7% to $87.80 per barrel Monday morning following the U.S. seizure of an Iranian cargo ship and Iran's abrupt reversal on reopening the Strait of Hormuz. Iran declared the strait would remain closed less than 24 hours after announcing it was open, signaling continued geopolitical tensions.

Negotiation Status:

President Trump announced U.S. negotiators would arrive in Pakistan Monday for talks, with the two-week ceasefire expiring Wednesday. Iran has not confirmed participation in face-to-face negotiations, appearing to hold out for better terms.

Iranian Demands:

Tehran is pushing back on three key issues: the ongoing U.S. blockade of Iranian ports (viewed as ceasefire violation), cessation of Israeli operations in Lebanon, and refusal to surrender enriched uranium. Iran's parliamentary commission proposed new security fees for Strait of Hormuz passage.

Market Impact:

S&P 500 futures fell 0.3% Monday morning, though remained well above Sunday evening lows. The index rose 4.5% last week (best gain since mid-May 2025) and is up 4.1% year-to-date, having climbed 12.3% since the Iran war low on March 30.

Energy stocks led Monday's gainers, with Coterra Energy, Diamondback Energy, APA, Valero Energy, and Occidental all up 1-2%.

Oil Price Outlook:

CME Group futures indicate crude oil could fall below $80 per barrel by September and below $75 by year-end. Oil had topped $100 last week before Friday's plunge to $81.
