Iran Ceasefire Timeline: From Oman to Islamabad to the Edge of War (April 22, 2026)

# Iran Ceasefire Timeline: From Oman to Islamabad to the Edge of War (April 22, 2026)

> **Quick answer:** The Iran-US ceasefire expires tonight, Wednesday April 22, at 7:50pm ET. The 14-day truce — brokered by Pakistan and announced April 8 — followed a year of failed Oman negotiations, a war that killed Iran's supreme leader on February 28, and 21 hours of inconclusive Islamabad talks. Four diplomatic reversals in the last 48 hours (collapse, then possible extension, then Vance scraps the trip, then talks back on) have left oil above $95 a barrel and markets in suspension. This is the complete chronology of how the world got here.

The ceasefire clock is running out. By 7:50pm Eastern tonight, a two-week truce that paused one of the most consequential military conflicts since 2003 will either hold — or expire into an outcome Trump has described as "lots of bombs start going off." For investors, consumers, and anyone watching oil prices spike above $95 a barrel, the Iran ceasefire timeline is not just history. It is the operating manual for what happens to your gas prices, your portfolio, and global trade in the next 24 hours.

This is the complete record: every key date, every turning point, and what the pattern reveals about whether a deal is actually possible today.

The conflict did not begin in February 2026. The diplomatic failure that made the war possible stretches back more than a year.
