US and Iran are reported to be heading back to Islamabad for a new round of talks as a two-week ceasefire approaches its scheduled end
The latest diplomatic movement between the United States and Iran points to a renewed effort to salvage a fragile truce. Two regional officials told reporters that teams led by US vice president JD Vance and Iran’s parliament speaker Mohammad Bagher Qalibaf are expected to arrive in Islamabad early on Wednesday to continue negotiations.
Pakistan-led mediators have been central to the process, even as state media in Iran denied that any official had already reached Pakistan’s capital.
That movement comes against the backdrop of an outlined two-week ceasefire brokered by Pakistan on 8th April that is due to lapse.
The first formal US–Iran session, held on 11th and 12th April, lasted more than 20 hours and produced extensive exchanges without a settlement. Delegates debated contentious topics including Iran’s nuclear programme, sanctions relief, frozen assets and the operational status of the Strait of Hormuz.
With time running out, mediators are reportedly pressing for technical talks to bridge differences.
Security and maritime access: what is on the table
One of the most immediate pressures in the negotiations is the status of maritime traffic. The Strait of Hormuz is a strategic chokepoint for global energy shipments, and actions there have direct consequences for trade and security. The US implemented a naval blockade of maritime traffic to and from Iranian ports on 13th April, enforced by a significant CENTCOM presence that included aircraft carriers and destroyers. In response, Tehran accused US forces of “piracy” and warned of reciprocal measures that could affect navigation across the Gulf, the Red Sea and the Sea of Oman.
Amid those tensions, Iranian authorities moved on 17th April to reopen the strait to all commercial vessels for the remaining period of the ceasefire, directing traffic along a coordinated route. Whether that reopening endures beyond the ceasefire or is undermined by naval interdictions and retaliatory steps will be a central focus of the Islamabad talks.
Economic ripple effects and market signals
Markets have reacted to the ebb and flow of diplomatic progress and naval activity. Brent crude traded at $94.89 per barrel on 16th April, reflecting a modest daily decline but sustained volatility since the outbreak of hostilities. UK natural gas benchmarks spiked amid supply concerns, with front-month contracts and LNG prices climbing sharply as the Strait’s status tightened. Analysts point to the potential for supply shortfalls to persist even if fighting stops, and global forecasts have been revised lower by major institutions.
The International Monetary Fund published a revised World Economic Outlook that lowered its global growth forecast and highlighted how a prolonged regional conflict could tip world growth toward recessionary territory. Meanwhile, the Energy Information Administration projected that Brent could peak near $115 per barrel in the second quarter of 2026 if disruptions continue. Energy-producing states have simultaneously taken steps to ramp up alternative output or repair damaged infrastructure to reduce acute market stress.
Regional diplomacy and key movements
Pakistan has maintained an active mediation role: delegations and senior officials shuttled between capitals to sustain momentum. On 15th April Pakistan’s army chief Field Marshal Asim Munir visited Tehran, carrying proposals and coordinating plans for a second negotiation round. Prime minister Shehbaz Sharif travelled to Gulf capitals — including stops in Saudi Arabia, Qatar and Turkey — to rally regional support and align diplomatic channels ahead of further meetings.
Wider regional responses and capabilities
Across the Gulf, governments took measures to shore up energy security. Saudi Arabia reported progress repairing the East-West pipeline, and announced preparations to raise output from fields such as Manifa. Qatar signalled readiness to restart LNG output at Ras Laffan where feasible, contingent on safe shipping corridors. The United Kingdom and a multinational coalition have also discussed plans to protect navigation through the strait, while Abu Dhabi criticised actions that obstruct maritime passage.
What to expect next
Diplomats are reported to be weighing a short extension to the existing arrangement to create breathing space for negotiations. As of 15th and 16th April, US and Iranian teams were considering a further two-week pause to allow technical discussions on the most sensitive issues, though US officials said Washington had not formally agreed to an extension. The stakes are clear: progress in Islamabad could ease both the security standoff and market disruptions, while failure would risk renewed escalation and deeper economic consequences.
Observers will watch whether the top negotiators arrive as reported, whether Islamabad can produce concrete technical compromises on the Strait of Hormuz and Iran’s nuclear commitments, and whether regional players sustain coordinated pressure to keep shipping lanes open. The outcome of these talks will shape both immediate maritime safety and the broader geopolitical landscape for months ahead.
