US and Iran Agree Ceasefire Deal to End Months-Long Conflict

The United States and Iran have reached a comprehensive ceasefire agreement aimed at ending a conflict that has lasted nearly four months, killed thousands, and disrupted global energy markets. Pakistani Prime Minister Shehbaz Sharif announced the breakthrough on Monday, June 15, with both American and Iranian officials confirming the agreement would be formally signed on Friday, June 19, in Switzerland. The accord calls for an immediate and permanent end to military operations on all fronts, including in Lebanon, and represents a significant diplomatic effort following intense negotiations mediated by Pakistan and Qatar.

US President Donald Trump hailed the agreement as a major achievement, stating that it would reopen the strategically vital Strait of Hormuz and lift the US naval blockade that had effectively closed one of the world's most critical shipping routes. "Let the oil flow!" Trump declared on social media, authorizing the immediate lifting of maritime restrictions. Iran's Deputy Foreign Minister Kazem Gharibabadi confirmed the agreement had been finalized and similarly framed it as a victory for Tehran, with Iranian state media describing it as a triumph for the Islamic Republic and the "resistance axis."

While the ceasefire represents a major step toward peace, several critical issues remain unresolved. The agreement establishes a 60-day ceasefire period during which both sides will negotiate more contentious matters, including Iran's nuclear program and the potential lifting of US sanctions. Additionally, the status of Lebanon and Israeli military operations against Lebanese militant group Hezbollah—which has been blamed for thousands of deaths—continues to pose complications. Israel has indicated it will resume military action if Hezbollah attacks Israeli territory, creating uncertainty over the durability of broader peace arrangements.

International markets responded positively to the ceasefire announcement. Brent crude oil prices fell 4 percent to $83.81 per barrel, while US crude declined 4.7 percent to $80.89 per barrel as traders anticipated the restoration of oil flows through the Strait of Hormuz. Asian stock markets also rose sharply, with Japan's Nikkei 225 gaining 4.3 percent and South Korea's KOSPI rising over 5 percent. However, energy experts cautioned that full restoration of pre-conflict oil transport levels would take weeks to months, as the waterway must first be cleared of mines and significant backlogs of tankers must be processed.

The agreement comes after escalating regional tensions that began with US and Israeli air strikes on Iran on February 28, prompting Iranian retaliation and the effective closure of the Strait of Hormuz. Through which approximately 20 percent of global oil and natural gas typically flows. The accord offers the prospect of stability but leaves numerous complex questions for future negotiations, particularly regarding Iran's nuclear capabilities and the involvement of regional actors like Israel and Hezbollah.
