President Donald Trump rejected extending a temporary ceasefire with Iran on Monday, as Tehran threatened to adopt a more aggressive military stance. The decision raises fresh concerns regarding the Strait of Hormuz, global oil supplies, and financial market stability.
The 60-day memorandum of understanding between the US and Iran expired without a broader peace agreement. The deal was intended to end military operations and pave the way for negotiations covering Iran’s nuclear program and US sanctions. When asked if Washington would extend the interim agreement, Trump said no, according to Reuters.
Geopolitical Tensions Escalate
A senior Iranian official stated that Tehran would shift to a "fully offensive" posture if diplomatic efforts fail. Iran accused Washington of failing to meet its commitments under the June agreement and warned it could take military action to challenge the US naval blockade.
The dispute centers heavily on the Strait of Hormuz, a critical energy route where tanker traffic has been severely disrupted during the conflict. Iran claims the agreement gives it a role in managing the waterway, while the US rejects that interpretation. Reports indicate the Trump administration has sought back-channel communication with figures connected to Iran’s Islamic Revolutionary Guard Corps, even as formal negotiations remain stalled.
