• Iranian President Masoud Pezeshkian told the UN that Tehran rejects nuclear weapons but will not surrender its right to peaceful nuclear technology, while signaling readiness for dialogue—but not under force or threats.

Nuclear Rights and the Limits of Diplomacy

Iran’s UN messaging this week combined two carefully calibrated positions: a rejection of nuclear weapons and a firm insistence on its right to civilian nuclear technology, with renewed diplomacy made conditional on the removal of military and economic pressure. President Masoud Pezeshkian, addressing the General Assembly, said Tehran “rejects nuclear weapons but will not surrender its right to peaceful nuclear technology.” The statement preserves Iran’s longstanding distinction between opposing a nuclear weapon and defending domestic enrichment—a distinction that remains fundamentally at odds with the U.S. objective, as described by President Trump, of permanently preventing Iran from obtaining a nuclear weapon.

The diplomatic environment is coercive rather than normalized. Trump coupled talk of a deal with explicit threats of much greater escalation, and Iran’s military leadership responded with threats of stronger retaliation if further attacks occur. “We are ready for dialogue and diplomacy, but not under force or threats,” Pezeshkian said, according to a transcript of his remarks.

Fragile Opening After Mediator-Led Talks

U.S. special envoy Steve Witkoff said U.S. and Iranian delegations completed a lengthy round of talks through mediators on September 22. Trump described the exchange as productive and said another meeting was expected, though accounts differ on whether there was a direct U.S.–Iran meeting. The talks, held on the sidelines of the UN General Assembly in New York, centered on the Strait of Hormuz, port restrictions, frozen assets, and the wider conflict.

Tehran has conveyed terms through mediators: easing U.S. military pressure, lifting the naval and port blockade, releasing frozen Iranian assets, and ending what Iran calls the wider war across “resistance” fronts. According to people familiar with the matter, Iran has reportedly said it could reopen the Strait of Hormuz within seven days if those conditions are met. The U.S. has not publicly responded to those specific terms, and officials from both sides did not immediately respond to requests for comment.

Hormuz: Economic Chokepoint and Bargaining Chip

The principal economic channel is energy and shipping risk. Hormuz is a critical transit route for Persian Gulf oil and gas exports, so actual or threatened disruption immediately affects tanker availability, insurance costs, regional export capacity, and oil-price expectations. On September 22, Brent crude fell below $100 per barrel as investors priced in the possibility of a diplomatic breakthrough and reports that Saudi Arabia’s East-West pipeline had resumed limited operations. That pipeline can route some Saudi crude to the Red Sea, reducing—but not eliminating—dependence on Hormuz.

Pezeshkian argued that Iran cannot allow others to benefit from the waterway while using it against Tehran. Western and regional governments, by contrast, regard unimpeded commercial passage as a core international economic and security interest. European Union foreign-policy chief Kaja Kallas met Iranian Foreign Minister Abbas Araghchi and called for free, unimpeded navigation through both Hormuz and the Bab el-Mandeb Strait, alongside an end to hostilities. Qatar, Oman, and Pakistan are participating in or supporting mediation efforts.

The market impact is already visible beyond oil. The U.S. has intensified economic pressure on Iran’s aviation sector, with reporting indicating that Iranian flights to Baghdad and Muscat were being canceled or disrupted as expanded sanctions took effect, although the scope and implementation varied by destination. A prolonged restriction on Hormuz would not only raise energy costs for importing countries; it could reduce export revenue for Iran and Gulf producers, increase freight and insurance premiums, and worsen inflation risks globally.

Verification Gap Clouds Any Deal

Even if a political framework emerges, international monitoring remains a major unresolved concern. Recent reporting has indicated that the International Atomic Energy Agency’s on-the-ground access in Iran has sharply deteriorated, making it harder to verify the condition, location, and quantity of Iran’s enriched uranium stockpile. That verification deficit is crucial: a political promise not to pursue nuclear weapons is more likely to be acceptable internationally if accompanied by restored IAEA access, credible accounting for nuclear material, and enforceable limits.

“It’s a great country to invest here because there are a lot of very good companies and the market here is not as competitive as other markets,” said Giampiero Mazza, head of Italy at CVC Capital Partners (CVC.AS), speaking at a separate event in Milan—a reminder that investor attention remains fixed on how the crisis resolves.

The current setting is far more dangerous than a conventional sanctions dispute. The wider war began in late February 2026 after U.S.–Israeli strikes on Iran, according to current reporting. The June understanding between the sides collapsed, after which security, sanctions, nuclear limits, and maritime access became even more intertwined. Two tankers were reportedly struck by projectiles or debris in Hormuz on September 21, with minor crew injuries in one incident.

What to Watch

The most plausible near-term outcome is continued mediated diplomacy rather than an immediate comprehensive deal. The sides have strong incentives to test negotiations: Iran wants relief from military and economic pressure, while the U.S., Gulf states, European countries, energy markets, and maritime industries want de-escalation and dependable passage through Hormuz. The main risk is that diplomacy remains hostage to incompatible sequencing—Iran ties reopening Hormuz to reduced pressure and an end to the blockade, while the U.S. and its partners insist free navigation should be restored without Iranian conditions or fees.

Domestic constraints matter for Pezeshkian. His UN appearance provides a diplomatic opening, but any compromise must be compatible with Iran’s security establishment and the authority of Supreme Leader Ali Khamenei. The reported authorization for Iran’s UN delegation to explore diplomacy suggests tactical flexibility, not necessarily agreement on the substance of a settlement. For now, the fact that officials are still talking is significant, but it should be viewed as an opening—not evidence that an agreement is close.
