The U.S. and Iran have signed a preliminary interim agreement to end their ongoing conflict, a move that includes a 60-day ceasefire and the reopening of the Strait of Hormuz. According to U.S. President Donald Trump, the deal is signed, though detailed terms remain under negotiation. While the agreement aims to stabilize global energy markets, shipping industry leaders warn that transit confidence may take weeks to return, and fundamental disagreements regarding Iran’s nuclear program and regional proxy support remain unresolved.
What are the terms of the U.S.-Iran interim deal?
The memorandum, confirmed by U.S. President Donald Trump on June 16, functions as a 60-day extension of a tenuous ceasefire that first began in April. According to U.S. officials, the agreement mandates the reopening of the Strait of Hormuz, a critical maritime chokepoint that facilitates roughly one-fifth of global oil trade. U.S. Vice President JD Vance described the document as a “very general” framework, noting that a formal signing ceremony is planned for Geneva. The agreement includes a significant sanctions relief package for Iran, which U.S. officials state is contingent upon Iran meeting specific demands regarding its nuclear ambitions and the cessation of support for militias such as Hezbollah.

Why do shipping companies remain cautious?
Despite the diplomatic breakthrough, the shipping industry is not immediately resuming full-scale operations through the Strait of Hormuz. The chief executive of Japan’s Mitsui O.S.K. Lines, which operates a fleet of over 900 vessels, told the Financial Times that shipowners require proof that the deal is “material” before navigating the waterway. Industry analysts suggest that even with an official agreement, the recent history of blockades makes insurers and operators wary. Mitsui O.S.K. Lines estimates that a full return to normal shipping traffic could take between two weeks and a month, depending on the stability of the security environment in the region.

The Strait of Hormuz is one of the world’s most vital oil transit points. When Iran effectively blocked the strait in February, global oil prices surged, impacting energy markets worldwide until the recent cooling of tensions.
How does the conflict in Lebanon impact the agreement?
The ongoing fighting between Israel and the Hezbollah militia remains a primary obstacle to a permanent peace. While Iran has insisted that the interim deal requires a total cessation of hostilities in Lebanon, Israeli Prime Minister Benjamin Netanyahu stated on June 16 that Israel would maintain its forces in the southern region. According to Netanyahu, Israel retains the “right to respond” to Hezbollah attacks, regardless of the U.S.-Iran memorandum. A U.S. official confirmed that an Israeli withdrawal from Lebanon is not a stipulated condition of the current interim agreement.
What happens to Iran’s nuclear and missile programs?
Negotiators are expected to address the future of Iran’s nuclear program during the next 60 days of talks. However, the scope of these negotiations remains limited. According to reports, the agenda does not currently include curbing Iran’s missile program or ending its support for regional armed proxies—two issues previously cited by the U.S. and Israel as primary justifications for the conflict. Iranian officials continue to deny intentions to develop nuclear weapons, characterizing the upcoming diplomatic discussions as a resumption of talks that were interrupted by the outbreak of war in February.
