Oil prices dropped about 7% on hopes of de-escalation, while equities rallied, with the Dow hitting a record high. However, the attack on a vessel in the Strait of Hormuz and the uncertainty over talks keep energy markets on edge, with potential for supply disruptions and higher volatility.
On August 4, 2026, conflicting statements from the United States and Iran over the status of negotiations to end their five-month-old war heightened uncertainty. President Donald Trump claimed talks were ongoing, calling it a 'last chance' for Iran, while Iranian Foreign Ministry spokesman Esmail Baghaei denied any negotiations were taking place or planned. The dispute was underscored by a reported attack on a cargo vessel near the Strait of Hormuz, with the UKMTO confirming the vessel was hit by an unknown projectile off Oman's coast. Iran has largely shut off transits through the strait, a vital route for about a fifth of global oil and gas shipments, and traffic remained slow. Oil prices fell about 7% on hopes of easing tensions, while the Dow Jones Industrial Average closed at a record high. The conflicting signals fit a pattern since Trump launched 'Operation Epic Fury' with Israel, where he has threatened military action only to step back. Iran has publicly rejected negotiations since the collapse of a memorandum of understanding in early July. The Hormuz dispute remains central, with Washington insisting the memorandum required Iran to open the waterway, while Tehran says it preserved its authority over shipping.
