Iran skips Islamabad talks: ceasefire at risk in 2026

Talks planned in Islamabad hit a sudden roadblock

Iran said it will not participate in a planned second round of talks with the United States in Islamabad, a decision that undercut hopes of extending a fragile ceasefire in a war nearing the two-month mark. The decision was reported by Iran’s state media, including the Islamic Republic News Agency (IRNA). It came hours after US President Donald Trump said American negotiators would be in Islamabad on Monday. The ceasefire is set to expire on April 22, keeping the diplomatic timeline tight. Pakistan had already tightened security in its capital in preparation for the meeting. Iranian sources had earlier indicated a delegation could arrive in Pakistan on Tuesday, making the reversal more abrupt. The talks were positioned as a critical step toward extending the truce, but Iran’s stance suggested the process had stalled again.

Iran’s stated reasons: “excessive demands” and a naval blockade

Tehran blamed its absence on what it called Washington’s “excessive demands, unrealistic expectations, constant shifts in stance, repeated contradictions”. Iran also cited an ongoing US naval blockade of its ports, which it described as a breach of the truce. Iranian media reports said there was “no clear prospect of fruitful negotiations” under current conditions. Iranian outlets also signalled the lifting of the blockade was a precondition for moving forward. Iran’s Foreign Ministry spokesperson Esmail Baghaei accused Washington of violating the ceasefire. Separately, Iranian Deputy Foreign Minister Saeed Khatibzadeh said the US was “risking the whole ceasefire package” with its blockade. Khatibzadeh also said Iran would not hand over its enriched uranium to the US, and that Tehran wanted a “framework agreement” before moving to an in-person meeting.

Aref and Qalibaf: diplomacy claims, but sharper rhetoric

At a high-level meeting on Sunday, Iran’s First Vice President Mohammad Reza Aref criticised the US approach, describing American positions as “childish” and inconsistent. He said the US sought a ceasefire and negotiations under pressure and then adopted a harder-line attitude afterward. Iran’s parliamentary speaker and negotiator Mohammed Bagher Qalibaf had earlier said there would be “no retreat in the field of diplomacy”. He also said there had been progress, but “many gaps” remained and the sides were “still far from the final discussion.” In another update, Iran’s Supreme National Security Council secretary Mohammad Bagher Zolghadr said Iran had received new US proposals via Pakistani intermediaries and was reviewing them. These statements reflected a mix of openness to dialogue and refusal to move on core demands. The gap between diplomatic signalling and operational realities, including the blockade dispute, remained central to the breakdown.

US delegation plans and Trump’s renewed threats

The White House said Vice President JD Vance, who led the first round of “marathon” talks last week, and other senior officials were preparing to travel to Islamabad. Separately, sources cited by CBS News said Vance, special envoy Steve Witkoff and Jared Kushner would travel for the talks. Trump, however, escalated pressure publicly. In a Truth Social post, he threatened to destroy civilian infrastructure in Iran if Tehran did not accept the US offer. He wrote that the United States would “knock out every single Power Plant, and every single Bridge, in Iran,” and vowed to end Tehran’s “killing machine.” Reports noted these threats drew criticism and warnings about war crimes. Trump also accused Iran of firing at ships transiting the Strait of Hormuz. The combination of negotiation claims and coercive messaging added to uncertainty around the ceasefire extension.

Pakistan’s intermediary role as the venue stays in focus

Pakistan has been positioned as a facilitator between Washington and Tehran. Pakistani Foreign Minister Ishaq Dar said he spoke by phone with Iran’s Foreign Minister Abbas Araghchi and that Pakistan was working to “bridge” differences. Dar also stressed the need for parties to continue to uphold the ceasefire. Islamabad had tightened security in anticipation of the talks, indicating the seriousness with which Pakistan treated the effort. But Iran’s decision to skip the round created a practical problem for the planned schedule. Even so, Iran’s state-run agency IRNA reported that Tehran was open to continuing the dialogue, while acknowledging the atmosphere was not positive. With the ceasefire deadline nearing, the ability of intermediaries to keep communications active became more important than formal meetings.

Strait of Hormuz: shipping disruption and rising security risks

Tensions around the Strait of Hormuz remained a major flashpoint. Iran announced the strait’s closure and warned any ship approaching it would be targeted, with reports saying hundreds of vessels were stranded at both ends of the waterway. Around one-fifth of the world’s oil supply passes through the strait, making disruptions globally significant. Another report said Iran had announced the strait’s reopening after a 10-day truce between Israel and the Iranian-backed Hezbollah in Lebanon took hold on Friday, but that Tehran later reversed course and continued restrictions as long as the US blockade remained. The US blockade was described as cutting off vessels from transiting to and from Iranian ports and coastal areas. Iran called the blockade an “act of aggression,” while the US framed it as pressure until a deal is reached. The net result was heightened uncertainty for commercial shipping routes.

India-linked incident: Indian-flagged vessels fired upon

The conflict spilled into India-linked maritime traffic through the Hormuz corridor. On Saturday, Iranian gunboats fired on two Indian-flagged merchant vessels, forcing them to turn back, according to reports. Separate sources said no injuries were reported and the vessels were not damaged. A distress audio clip related to one incident was also referenced in coverage. The episode underlined how quickly regional conflict can affect Indian shipping interests, even when India is not a party to the conflict. It also increased attention on insurance risk, routing decisions, and port scheduling for cargo moving through the Gulf. For Indian market participants, such incidents are typically watched for their potential link to freight costs and energy supply logistics.

Key sticking points listed by both sides

Reports repeatedly highlighted unresolved issues that derailed the first round and continued to block a second. These included Iran’s nuclear enrichment programme, Iran’s regional proxies such as Hezbollah, and control of the Strait of Hormuz. The US side has said Iran’s nuclear ambitions were a central dealbreaker. Vance has previously said deep mistrust between Washington and Tehran remained the biggest obstacle to peace. Iran has said it is not enriching uranium for a nuclear bomb and has maintained it is for power-generation purposes. Iran also raised demands ahead of talks, including financial compensation for damage from US-Israeli strikes, a halt to regional hostilities against proxy groups, and sovereignty over the strait. With the ceasefire clock running, none of these points appeared close to resolution based on the public positions described.

Market impact: what investors will watch in India

The article’s core market-sensitive variable is the status of the Strait of Hormuz, given the share of global oil supply that passes through it. Reports said oil prices had surged because of the closure of the strait, but no specific price levels were cited. For Indian investors, the channel is relevant because shipping disruptions and higher risk premiums can feed into landed energy costs and freight availability. The firing incident involving Indian-flagged vessels also puts focus on maritime insurance and route changes, even without damage reported. The other market factor is whether the ceasefire is extended before April 22, since the talks were described as central to sustaining the truce. Investors will also track whether the blockade remains “in full force,” as Trump stated, because it directly links economic pressure to negotiation timelines.

What happens next before April 22

Based on the reporting, the immediate next step is whether Iran sets any date for direct talks and whether the US shifts its stance on the blockade. Iran’s Foreign Ministry has separately said no date was set for new direct negotiations, even as indirect engagement continued. Pakistan has said it will try to facilitate a new round of dialogue “in the coming days.” Iran also said it was reviewing new US proposals delivered via Pakistani intermediaries. With both sides publicly reiterating hard positions on nuclear enrichment and Hormuz, near-term movement appears tied to procedural steps such as agreeing on a framework and resolving the blockade dispute. Any confirmed meeting schedule or formal statement on extending the ceasefire before April 22 will be the next clear signal for markets to parse.
