The United States and Iran have carved out substantial common ground toward a comprehensive 60-day ceasefire extension, though President Donald Trump is withholding final authorisation as critical language points remain under review, Vice President JD Vance confirmed.
The diplomatic breakthrough comes at a pivotal moment for global energy stability. High-stakes negotiations, quietly brokered in Qatar and Pakistan, aim to solidify a fragile truce initially established in April. The proposed 60-day framework would formalise a cessation of hostilities, reopen the blockaded Strait of Hormuz, and initiate structured negotiations regarding Tehran’s nuclear ambitions.
Vance signals “a lot of progress” amid lingering friction
Speaking to reporters in Washington following reports that a tentative memorandum of understanding had been reached, Vice President Vance expressed measured optimism regarding the trajectory of the secret diplomacy.
“We’re going back and forth on a couple of language points. We’ve made a lot of progress here,” Vance stated. “Hopefully, we’ll continue to make progress and the president will be in a position where he can endorse the agreement, but obviously that’s still TBD.”
The cautious rhetoric from the White House reflects a delicate balancing act. While Vance noted that Washington believes Iranian negotiators are engaging in “good faith", President Trump has publicly maintained a hardline stance. Earlier in the week, the president instructed his Cabinet that he would not be “rushed into a deal", signalling that the final terms must meet stringent American demands before receiving executive validation.
The strategic geometry of the Hormuz dilemma
For global oil markets, the stakes could not be higher. The conflict has severely disrupted transit through the Strait of Hormuz, a critical maritime chokepoint through which approximately 20% of global petroleum supply flows. A partial naval blockade enforced by US Central Command (CENTCOM)—coupled with intermittent maritime skirmishes—has driven significant volatility, with Brent crude tracking near $92.66 a barrel and WTI at $87.88.
Energy analysts emphasise that a verified diplomatic breakthrough is the only immediate mechanism capable of stabilising supply chains. Regional overland pipeline alternatives, such as the Saudi East-West Pipeline or the UAE’s Habshan-Fujairah link, possess a combined maximum bypass capacity of roughly 7 million barrels per day. This leaves a structural shortfall of 13 million barrels per day compared to normal daily Hormuz throughput, rendering alternative routing fundamentally inadequate to offset a prolonged blockade. Furthermore, specialised shipments of liquefied natural gas (LNG) bound for Asian markets remain entirely dependent on the strait.
A tenuous truce on the ground
The ongoing diplomatic push is complicated by a highly volatile security environment on the ground. Despite the overarching diplomatic framework, localised infractions have continually threatened the stability of the April truce.
Tensions spiked earlier in the week following targeted US strikes on Iranian vessels near the strait, which CENTCOM characterised as strictly defensive measures. Concurrently, regional proxy dynamics continue to cloud the negotiation track. While a draft layout of the memorandum reportedly includes a conditional US commitment to ease naval restrictions and draw down certain regional assets, sticking points remain acute.
Central among these is Washington’s insistence on verifiable guarantees that Iran will permanently halt uranium enrichment and dismantle core facilities. Conversely, negotiators in Tehran are pressing for extensive sanctions relief and the release of frozen sovereign assets abroad as prerequisites for a long-term settlement.
As negotiators refine the specific legal terminology of the text, the energy sector remains on high alert. A confirmed 60-day extension would provide a critical operational window for international shipping lines, but until President Trump delivers his definitive endorsement, the risk of a swift return to open conflict remains real.
