The United States and Iran reached a tentative agreement Thursday to extend their ceasefire by 60 days [1].

The deal aims to end a month-long war and reopen critical shipping lanes in the Strait of Hormuz. If finalized, the agreement would establish a framework for further negotiations regarding Iran's nuclear program [1, 2].

The memorandum of understanding was reached on May 28, 2026 [1]. It focuses on lifting restrictions on maritime trade through the Strait of Hormuz, a vital artery for global energy supplies. However, the agreement remains pending the final sign-off from President Donald Trump (R-WY) [1, 3].

Diplomatic efforts have been intensifying throughout the month. On May 23, 2026, President Trump said, "The agreement has been largely negotiated" [2]. Despite that progress, the final steps have remained cautious. The U.S. vice president said on May 28 that the two nations are "very close" to a deal, but are "not there yet" [3].

The agreement comes amid a volatile security environment. While some reports indicate recent hostilities, including strikes on Iranian territory and retaliatory attacks on a U.S. base [3], other reports focus exclusively on the diplomatic push to maintain the ceasefire extension [1].

The proposed 60-day window [1] is intended to provide a cooling-off period. This temporary pause allows both administrations to determine if a long-term diplomatic solution is viable or if the region will return to active conflict.

The U.S. and Iran are "very close" to a deal, but are "not there yet."

The tentative nature of this agreement underscores the fragility of U.S.-Iran relations. By focusing on the Strait of Hormuz, both parties are prioritizing the stabilization of global oil markets and maritime trade over immediate political resolution. The 60-day extension serves as a strategic bridge, allowing the Trump administration to test Iran's compliance before committing to a broader nuclear framework.
