President Donald Trump has rejected extending a temporary Iran ceasefire, leaving diplomatic efforts deadlocked as a 60-day memorandum of understanding expired on Monday. The interim agreement, originally signed on June 17, declared an immediate and permanent termination of military operations on all fronts and provided a 60-day time frame to negotiate a broader deal covering Iran’s nuclear programme and U.S. sanctions.
Ceasefire Agreement Expires as US-Iran Peace Talks Stall
The arrangement quickly unraveled over a dispute regarding control of the Strait of Hormuz. Point 5 of the memorandum gave Iran the right to manage the strategic waterway, which it shares with U.S. ally Oman, an interpretation that the United States rejected. Following the breakdown of the pact, hostilities resumed, with Iran firing on vessels attempting to sail through unapproved routes, leading Trump to declare on July 7 that the agreement was over. When asked by reporters on Monday whether Washington would seek to extend the interim agreement, Trump said no.

Tehran Warns of Offensive Military Posture and Precise Attacks
Following the collapse of the talks, a senior Iranian official told Reuters on Monday that Iran will shift to a fully offensive
military posture and conduct a timely and precise
military attack to break the U.S. naval blockade. The official stated that Iranian entities must be prepared to escalate tensions in the Strait of Hormuz and the wider region to take difficult decisions if diplomacy fails.

Concurrently, shipping activity through the Strait of Hormuz has remained at a trickle, with preliminary Kpler ship-tracking data showing that only six commodity ships transited the strait, compared to a 10-day average of 11 ships. The United Kingdom Maritime Trade Operations (UKMTO) reported that a vessel was struck by an unknown projectile while transiting outbound in the Strait of Hormuz, damaging its engine room and causing a crew casualty, with the remaining crew assisted by the Omani Coast Guard. Meanwhile, Iran has separately been negotiating an agreement on managing the strait with Oman. In response to those separate talks, Trump issued a threat against the Gulf state, telling Fox News, If Oman gets in the way, we’ll bomb the s**t out of them

Oil Prices Climb and Markets React to Escalating Tensions
The breakdown of the peace agreement and the ongoing disruptions in the Strait of Hormuz have impacted global financial and commodity markets. Oil prices climbed for a third consecutive session on Tuesday, with Brent crude rising above US$91 a barrel and US West Texas Intermediate moving toward US$85. Tim Waterer, chief market analyst at KCM, noted that oil jumped to start the week as U.S.-Iran relations look increasingly shaky, a deal to reopen the strait is not in sight, and shipping numbers remain at a trickle.
Financial markets also registered the strain of the geopolitical uncertainty. Dow futures fell 10.00 points to 53,534.00, S&P 500 futures declined 2.25 points to 7,766.50, and Nasdaq 100 futures slipped 4.75 points to 30,091.25. In foreign exchange markets, traders sold off the U.S. dollar amid concerns over economic strength and Middle East developments, pushing the dollar index down to 99.559.
