On June 17, 2026, US President Donald Trump signed the Islamabad Memorandum at the Palace of Versailles, and Iranian President Masoud Pezeshkian signed it in Tehran. The agreement, brokered with significant Pakistani diplomatic involvement, was intended to end a war that had been escalating since early 2026 — a conflict between US and Israeli forces on one side and Iran on the other, centred on Iran’s nuclear programme, control of the Strait of Hormuz, and regional dominance in the Middle East.
Thirteen days later, the ceasefire is showing signs of collapse. As of June 30, 2026, the US has carried out fresh strikes on Iranian military facilities, Iran has responded with drone attacks on shipping in the Strait of Hormuz, and the two sides cannot agree on whether talks are even happening. For Pakistan — which lent its name and its capital city to the most significant diplomatic document of the conflict — the stakes could not be higher.

What Is the Islamabad Memorandum?
The Islamabad Memorandum is the name given to the ceasefire framework agreed between the United States and Iran in June 2026. The name reflects Pakistan’s role as a backchannel facilitator — a country with functional diplomatic relations with both Washington and Tehran, and a track record of hosting sensitive multilateral negotiations.
The specific terms of the memorandum, as publicly reported, included a halt to US and Iranian military operations against each other’s forces and proxies, the lifting of the US naval blockade of Iranian ports, a framework for further negotiations on Iran’s nuclear programme, and an agreement to refrain from strikes on civilian infrastructure. The memorandum did not resolve the underlying dispute over Iran’s nuclear enrichment — it was explicitly described as a temporary ceasefire, not a peace agreement.
Pakistan’s Diplomatic Role: Why Islamabad?
Pakistan is one of the very few countries in the world that maintains functioning diplomatic relations with both the United States and Iran. It has a long history of engagement with Tehran — the two share a 900-kilometre border, significant trade and energy ties, and a shared interest in regional stability in Afghanistan. At the same time, Pakistan’s defence relationship with the United States, while complicated, remains one of the central anchors of its foreign policy.
This dual positioning — neither a US ally in the full NATO sense, nor a member of the Iranian-led resistance axis — gave Pakistan a rare diplomatic window. When direct US-Iran contacts stalled in May 2026, Islamabad offered to provide a backchannel through which messages could be conveyed, terms could be tested, and face-saving language could be developed for both sides.
The fact that the agreement carries the name “Islamabad Memorandum” is significant. It is the first major international peace framework named after a Pakistani city since the country’s early years of active multilateral diplomacy. For Pakistan’s foreign ministry, it represents a meaningful restoration of diplomatic relevance at a moment when the country’s international profile has been constrained by domestic political instability and economic crisis.
Impact on Oil Prices and Pakistan’s Economy
| Period | Brent Crude Price (approx.) | Impact on Pakistan |
|---|---|---|
| Pre-conflict (Jan 2026) | ~$78/barrel | Stable import bill; inflation under control |
| Peak conflict (April–May 2026) | ~$122/barrel | Fuel import costs surged; PKR under pressure; inflation spike |
| Post-Islamabad Memorandum (June 17) | ~$91/barrel | Partial relief; import bill eased; PKR stabilised slightly |
| Post-ceasefire breakdown (June 27–30) | ~$105/barrel | Renewed uncertainty; SBP monitoring closely |
Pakistan imports nearly all of its crude oil. A $1 increase in the price of Brent crude costs Pakistan approximately $600 million per year in additional import expenditure. The spike to $122/barrel between April and May 2026 represented an annualised increase of roughly $26 billion compared to January levels — a shock that the country’s foreign exchange reserves and trade deficit could not easily absorb.
The Islamabad Memorandum provided meaningful — if temporary — relief. The fall from $122 to $91 per barrel in the immediate aftermath of the ceasefire announcement reduced the acute pressure on Pakistan’s balance of payments. The subsequent partial reversal, back to around $105 as the ceasefire showed signs of strain, underlines how closely Pakistan’s economic fortunes are tied to a conflict it is trying to help end.
The Strait of Hormuz: Why It Matters for Pakistan
Approximately 20% of the world’s oil supply — and roughly 30% of global liquefied natural gas (LNG) trade — passes through the Strait of Hormuz, a narrow waterway between Iran and Oman at the mouth of the Persian Gulf. Iran has repeatedly threatened to close the strait in the event of military confrontation with the United States, and has made limited attempts to disrupt shipping through it during the 2026 conflict.
For Pakistan, the strait is not just an abstract geopolitical concern. Pakistan’s LNG imports — which supply a significant portion of its power generation capacity — pass through it. A sustained closure of the strait would not merely raise fuel prices in Pakistan; it would risk electricity blackouts and industrial shutdowns on a scale that would dwarf the load-shedding crises of recent years.
What Happens Next?
As of June 30, 2026, the outlook is uncertain. Iran is insisting on control of the Strait of Hormuz as a condition of further talks. The US is demanding verification mechanisms for any nuclear agreement before it will commit to a formal peace process. Both sides are accusing the other of having violated the terms of the Islamabad Memorandum first.
Pakistan’s foreign ministry has maintained a public posture of quiet engagement — expressing support for continued dialogue without explicitly criticising either side. This is a difficult balance to maintain as the ceasefire frays, but it is the only position that preserves Islamabad’s utility as a mediator.
The most optimistic scenario is that US-Iran talks resume in Doha in early July 2026, as Trump has suggested, and that the Islamabad Memorandum forms the basis for a more durable agreement. The most pessimistic scenario is a resumption of large-scale hostilities, oil above $130 per barrel, and a Strait of Hormuz crisis that shocks the global economy — including Pakistan’s fragile recovery.
Frequently Asked Questions
What caused the Iran-US war in 2026?
The 2026 Iran-US conflict escalated from a combination of factors: coordinated US-Israeli strikes on Iranian nuclear facilities, Iranian retaliation against US military bases in the Gulf, and a broader contest over control of the Strait of Hormuz. The conflict had been building for years through sanctions, proxy confrontations, and failed nuclear negotiations — the 2026 escalation was the most direct military confrontation between the two countries since the 1980 hostage crisis period.
Is Pakistan at risk of being drawn into the conflict?
Pakistan has carefully positioned itself as a neutral mediator rather than a participant. It shares a border with Iran and maintains significant economic and energy ties with the country, but it also depends on US financial support and IMF arrangements that would be jeopardised by any alignment with Tehran. Pakistan’s strategy has been to use its dual positioning as diplomatic leverage rather than be forced to choose sides — the Islamabad Memorandum is the clearest expression of that strategy.
