Iran bombarded Qatar with hundreds of missiles and drones this spring, destroying roughly 17 percent of its gas export capacity. On Friday, a Qatari negotiating team landed in Tehran anyway — the first credible diplomatic backchannel to emerge since the Iran war’s fragile ceasefire began falling apart.

The delegation traveled in coordination with Washington, according to a source with knowledge of the matter who spoke to Reuters, and is tasked with helping “reach a final deal that would end the war and address outstanding issues with Iran.” Secretary of State Marco Rubio, speaking at a NATO gathering in Sweden, acknowledged that Gulf states had their own interests at stake but insisted Pakistan remains the primary interlocutor, having done an “admirable job.”

The team’s presence is the clearest signal yet that both sides are searching for an exit from a conflict that has killed thousands and upended global energy markets. It is also an act of extraordinary pragmatism: Qatar halted liquefied natural gas production at Ras Laffan in March after Iranian strikes and has been hemorrhaging revenue since.

Oil’s Whiplash Week

Global oil markets have spent the week oscillating between hope and dread. Brent crude futures fell nearly 6 percent on Wednesday, settling at $105.02, after President Donald Trump told reporters that negotiations with Iran were in their “final stages.” By Friday morning, Brent had crept back to $104.24 as traders digested the gap between the president’s optimism and the situation on the ground.

“Believe me, if we don’t get the right answers, it goes very quickly,” Trump said at Joint Base Andrews. “Ideally I’d like to see few people killed, as opposed to a lot. We can do it either way.”

He also revealed he had been an hour away from ordering fresh attacks this week at the request of several Gulf neighbors before pulling back. The market whiplash between peace talk and escalation threats has become the conflict’s defining dynamic. Fujitomi Securities analyst Toshitaka Tazawa noted that investors are trying to gauge whether the sides can find common ground “with the U.S. stance shifting daily.”

On a weekly basis, Brent is down 4.6 percent and West Texas Intermediate has fallen 7.6 percent — declines that sit atop months of violent swings driven by the Strait of Hormuz closure. Before the war, roughly 20 percent of global energy supplies transited the waterway daily. Iran’s blockade has removed about 14 million barrels per day from the market. Even if the conflict ended today, full flows would not resume before early 2027, according to the head of the UAE’s ADNOC.

The Sticking Points

The outlines of a possible deal have been visible for weeks. Whether the remaining gaps can be closed is another matter.

A senior Iranian source told Reuters that no agreement had been reached but differences had narrowed. The two principal disputes are Iran’s stockpile of near-weapons-grade enriched uranium and Tehran’s insistence on maintaining control over the Strait of Hormuz — formalized this week by the creation of a “Persian Gulf Strait Authority” to administer traffic. Washington has called that unacceptable.

Iran’s broader demands include compensation for war damage, a full lifting of sanctions, the release of frozen assets, the withdrawal of US forces from the region, and an end to conflicts in Lebanon, Iraq, and Yemen — not just Iran. Tehran submitted a new offer this week that, according to officials familiar with its contents, largely repeats terms previously rejected by Washington.

Trump has said the US will not allow Iran to acquire a nuclear weapon, and his administration’s stated aims include dismantling Iran’s missile capabilities and curbing its support for regional militias. Iran has so far retained both its enriched uranium stockpile and its ability to threaten neighbors.

Rubio offered a measured note of progress on May 21: “There’s some good signs. I don’t want to be overly optimistic… So, let’s see what happens over the next few days.”

A Ceasefire That Never Quite Held

The current pause in fighting traces to April 8, when a two-week ceasefire was announced through Pakistani mediation. It was supposed to reopen the Strait of Hormuz immediately.

It did not.

Iran lost track of mines it had planted in the waterway. The US began a naval mine-clearing operation. Israel, which agreed to the ceasefire, launched its heaviest attacks on Lebanon within hours. Iran paused Hormuz traffic in response. Vice President JD Vance flew to Islamabad for talks on April 11 and left the next day empty-handed. Trump responded with a full naval blockade of Iranian ports.

The ceasefire has since been violated by both sides. It has been extended but never properly enforced.

Why Qatar, and Why Now

Qatar’s return to mediation is as pragmatic as it is improbable. Before the war, roughly 20 percent of global LNG trade passed through the Strait of Hormuz, most of it Qatari. Iran’s closure has cut off virtually all of that capacity. The economic damage to Doha is existential.

The country hosts Al Udeid Air Base, the largest American military installation in the Middle East, and served as a trusted backchannel between Washington and Tehran for years, including during the Gaza war. Its willingness to engage now — despite having been directly attacked by the government it is negotiating with — reflects both desperation and leverage. No country has more to lose from a prolonged Hormuz closure, and few have better lines of communication to both sides.

Pakistan’s interior minister was also in Tehran on Wednesday, continuing the official mediation track. But Doha’s parallel channel adds a second diplomatic route at a moment when the first has stalled.

What Comes Next

The consequences of failure extend well beyond the Persian Gulf. Capital Economics expects supply disruptions to stretch into 2027. BMI has raised its 2026 average Brent forecast from $81.50 to $90. Citi projects Brent could hit $120 in the near term; Wood Mackenzie has warned it could approach $200 if Hormuz stays shut through year’s end.

Trump faces mounting political pressure, with surging gasoline prices and congressional elections in November. Iran’s President Masoud Pezeshkian said Tehran remains open to talks, but added: “forcing Iran to surrender through coercion is nothing but an illusion.”

Two Chinese supertankers carrying roughly 4 million barrels of oil exited the Strait on Wednesday under eased Iranian restrictions — a reminder that even amid blockade, selective commerce continues. Iran also announced a new “controlled maritime zone” at the Strait, saying transit would require authorization and potentially fees.

The war has not stopped. The diplomacy has not yet succeeded. But for the first time in weeks, there are two channels open in Tehran, and both sides are still talking.
