Iran War timeline: 60 days from war to negotiations

The June 2026 memorandum of understanding between Washington and Tehran created a sixty-day window that could still determine whether the Iran War settles into verifiable limits or slides back into open fighting. The deal reopened the Strait of Hormuz without tolls, froze active strikes, and launched working groups on sanctions, nuclear oversight, and Lebanon deconfliction. For markets watching oil prices and for households facing another summer of energy volatility, the next two months matter more than any single headline from the preceding four.

War begins with mass strikes

American and Israeli forces opened the campaign on February 28 with nearly nine hundred strikes inside twelve hours. Targets included Iranian air defenses, missile sites, and senior command nodes. Supreme Leader Ali Khamenei survived, yet the opening barrage set the tempo for weeks of Iranian missile and drone replies plus Hezbollah rocket fire from Lebanon.

The rapid escalation closed the Strait of Hormuz to regular tanker traffic and sent global fuel benchmarks higher within days. U.S. naval units imposed a de facto blockade while Iranian speedboats harassed shipping lanes. Casualty counts climbed into the thousands and Lebanon absorbed the largest refugee wave since 2006.

Washington framed the operation as a necessary correction after earlier nuclear talks collapsed. Tehran described the strikes as unprovoked aggression. Both sides entered a prolonged exchange that lasted roughly one hundred eight days before any formal pause.

Proxy fronts widen the fight

Hezbollah’s involvement turned southern Lebanon into a second front and stretched Israeli reserves across two borders. Iranian-supplied drones reached Israeli cities, while U.S. carrier groups rotated through the eastern Mediterranean to deter wider spillover. Regional displacement numbers climbed quickly, drawing quiet pressure from Gulf capitals worried about their own security.

Oil traders tracked daily Hormuz transits and priced in the risk of a prolonged closure. European refiners shifted cargoes months ahead, while Asian buyers leaned on strategic reserves. The economic drag reached U.S. drivers through higher pump prices and airline surcharges that appeared on summer bookings.

Inside Washington, the White House balanced demands from hawks for deeper strikes against warnings from energy analysts about sustained price spikes. The debate shaped the eventual decision to test a diplomatic off-ramp once battlefield momentum stalled.

Mediation quietly takes shape

Pakistan and Qatar opened back-channel lines in May, testing whether both capitals would accept a structured pause. Early feelers produced the outline of a fourteen-point memorandum that avoided final nuclear language yet committed each side to a sixty-day negotiation track. Trump publicly labeled the period extendable by mutual consent, lowering the political temperature around a hard deadline.

Electronic signatures circulated between Versailles and Tehran in mid-June. The text reopened Hormuz traffic without fees for at least sixty days and established three working groups covering sanctions relief, nuclear verification, and Lebanese cease-fire mechanics. Signatories scheduled the first technical sessions for Bürgenstock, Switzerland.

Regional governments welcomed the breathing space even while withholding formal endorsement. Markets registered the announcement with an immediate drop in near-term oil futures, though analysts cautioned that any single incident at sea could erase the gain.

Sixty-day clock starts ticking

The memorandum took effect around June 17, setting the formal negotiation window that ends in mid-August unless extended. Oversight teams began comparing data on missile inventories and enrichment levels while sanctions specialists mapped which frozen assets might move first. Progress reports stayed deliberately vague to avoid inflaming domestic audiences on either side.

Trump described the period as a test rather than a guarantee, noting that success hinged on measurable steps rather than statements. Iranian officials echoed the caution, stressing that any sanctions relief must arrive in verifiable tranches tied to enrichment caps. Both sides kept public messaging short to preserve negotiating room.

Energy desks adjusted models to assume Hormuz remains open through August. Refiners booked extra cargoes while insurers trimmed war-risk premiums, yet contracts still carried clauses allowing quick reversal if talks broke down.

Technical teams gather in Switzerland

Lower-level delegations convened at Bürgenstock in late June to translate the MOU into operating procedures. Discussions covered inspection schedules for enrichment sites, definitions of permissible naval escorts through the strait, and sequencing for asset unfreezing. Early sessions produced shared spreadsheets rather than breakthroughs, yet participants described the tone as businesslike.

Qatari mediators shuttled between rooms while U.S. and Iranian experts avoided direct contact. Daily summaries reached Washington and Tehran by secure cable, feeding internal debates over acceptable risk levels. The process deliberately deferred the hardest nuclear questions until basic confidence measures were in place.

Press access remained limited. Reporters covering the talks noted the absence of the usual leaks, an indicator that both capitals wanted to control the narrative until concrete deliverables emerged.

Doha round tests implementation

Follow-up meetings moved to Doha in early July, focusing on traffic-management schemes for tankers and the mechanics of sanctions waivers. Vice President Vance stated that conversations were “going well,” a phrase repeated across wire reports and quickly echoed on financial television. Iranian delegates countered that any sanctions step must match enrichment concessions in real time.

Working groups circulated draft texts on maritime deconfliction and on the monitoring cell that will track compliance inside the strait. Observers noted that small technical agreements, such as shared radar feeds, could build momentum even before political leaders revisit the nuclear file.

Market analysts tracked every public comment for signs of slippage. A single negative headline still moved crude futures more than the incremental progress reports, underscoring how thin the current calm remains.

Lebanon deconfliction stays linked

The MOU explicitly ties a Lebanese cease-fire to the wider package, giving Hezbollah an incentive to observe the sixty-day pause. Israeli officials have conditioned any drawdown on verified Iranian weapons withdrawal from the Bekaa Valley. Lebanese political factions, already strained by refugee inflows, watch for signs that the talks could relieve pressure on their own borders.

Regional displacement figures continue to shape donor conferences in Europe and the Gulf. Aid agencies warn that any renewed fighting would overwhelm existing camps and push new waves toward Turkey and Jordan. The humanitarian ledger therefore sits beside the nuclear and sanctions files on negotiators’ desks.

Diplomats describe Lebanon as the easiest early deliverable because neither side wants to fight a two-front war through summer. Still, the timetable for verified withdrawals remains under discussion and could slip if other working groups stall.

Markets price the uncertainty

Oil traders now treat the August deadline as a soft option date. Futures curves show a modest contango reflecting the chance that Hormuz tolls could return or that fresh sanctions might tighten supply. Refiners have increased floating storage in Singapore and Rotterdam as a hedge against sudden reversals.

Airlines and shipping firms embed fuel surcharges that adjust monthly, passing costs to passengers and freight customers. Inside the United States, regional utilities model scenarios in which a collapsed deal adds several cents to summer electricity bills in the Southeast and Southwest.

Analysts note that any visible progress on asset releases could shave several dollars off benchmark crudes before the next OPEC+ meeting. Conversely, a single high-profile incident at sea would erase those gains within hours and force the negotiators back to square one.

Nuclear talks still ahead

Enrichment limits and verification protocols remain the largest outstanding items. The MOU defers detailed discussion until the working groups establish baseline data and confidence measures. Iranian negotiators have signaled willingness to cap centrifuges in exchange for phased sanctions relief, while U.S. officials insist on time-bound, intrusive inspections.

Previous rounds in Oman and Rome collapsed over verification disputes. The current format attempts to sequence easier issues first, yet both sides know that failure on enrichment numbers would render the rest of the MOU moot. The sixty-day window therefore functions as much as a forcing mechanism as a calendar.

IAEA inspectors await instructions on expanded access, and member states watch for early signs that the new framework can survive domestic pushback in Washington and Tehran alike.

Next steps rest on measurable delivery

The coming weeks will test whether modest technical agreements can scale into a durable package that addresses nuclear limits, sanctions sequencing, and Lebanese stability. Success would mark the first structured off-ramp since the Iran War began; failure would return both sides to a battlefield whose costs have already proved steep for civilians and markets alike. The sixty-day period therefore functions less as a finish line and more as the first real checkpoint on a longer road.
