U.S. and Iran Sign Deal to End 100-Day War
The US-Iran ceasefire deal is the single biggest geopolitical development of the day — ending a 100-day war, reopening the Strait of Hormuz, sending oil prices sharply lower and stocks surging. It directly affects US foreign policy, energy prices, and global stability. Israel’s refusal to comply adds immediate tension.
The Morning Brief Desk · · Updated June 18, 2026 · How the Brief is made
The United States and Iran agreed to a framework extending their ceasefire for 60 days, with a formal signing ceremony expected Friday and nuclear talks to follow. The deal ends a 100-day war that destabilized the Middle East and rattled global energy markets. The agreement includes the reopening of the Strait of Hormuz, sending oil prices sharply lower and equity markets higher.
The deal left critical issues unresolved, setting them aside for further negotiations. Israel immediately complicated the agreement: Israel’s defense minister said the country would not withdraw from territory seized in Lebanon, a condition tied to the broader settlement. Reuters reported that Prime Minister Benjamin Netanyahu and President Trump are now on a collision course over the terms. Netanyahu had counted on the conflict to topple Iran’s clerical government.
