US and Iran Sign Interim Peace Deal to Reopen Strait of Hormuz, but 60-Day Clock Hits Early Snag

The 110-day war between the United States and Iran has reached a fragile pause. Following months of devastating conflict that choked off global energy supplies, the two nations have signed the "Islamabad Memorandum of Understanding"—a 14-point interim peace agreement designed to halt hostilities and reopen the Strait of Hormuz.[4][7]

The immediate economic stakes are massive. The Strait of Hormuz is a critical maritime chokepoint that handles approximately 20% of the world's petroleum supply. Its closure in late February sent shockwaves through the global economy, fueling inflation and market panic.[8]

Following the deal's announcement, global markets breathed a collective sigh of relief. Brent crude oil prices plunged below $79 a barrel, erasing months of war-driven premiums, while European and US equities rallied on the prospect of stabilized energy costs.[1][8]

The core mechanism of the interim deal involves synchronized, immediate concessions. The United States has officially lifted its naval blockade on all maritime traffic entering and exiting Iranian ports. In exchange, Iran has agreed to immediately reopen the Strait of Hormuz to commercial vessels.[3][4]

Crucially, the agreement grants Iran immediate economic relief. The US Treasury Department is mandated to issue waivers for the export of Iranian crude oil, petroleum products, and associated banking services. This allows Tehran to resume selling oil on the global market while the broader framework is negotiated.[4][7]

However, the memorandum is not a final peace treaty. Instead, it establishes a 60-day window for direct negotiations to resolve the conflict's most intractable issues, including the future of Iran's nuclear program and the unfreezing of Iranian assets.[4][7]

The agreement explicitly calls for the "immediate and permanent termination of military operations on all fronts, including in Lebanon." This clause effectively requires Iran to rein in Hezbollah, the Tehran-backed militant group that has been engaged in intense cross-border fighting with Israel.[4][6]

Yet, the 60-day clock has already hit a significant snag. Vice President JD Vance, tapped to lead the US negotiating team, was scheduled to fly to Obbürgen, Switzerland, to begin technical talks with his Iranian counterparts. That trip was abruptly delayed on Thursday evening.[2][5]

The delay reportedly stems from Iranian protests over Israel's continued military operations in southern Lebanon. Iranian officials have indicated that their full compliance with the memorandum—particularly regarding the Strait of Hormuz—is contingent on Israel halting its campaign against Hezbollah.[5][6]

Israel, which is not a signatory to the US-Iran deal, has fiercely criticized the agreement. Israeli officials view the memorandum as a capitulation that provides Tehran with a financial windfall while leaving Hezbollah's military infrastructure intact on Israel's northern border.[3][6]

The Israeli pushback prompted a sharp rebuke from the US administration. Vice President Vance warned Israeli leaders to "wake up and smell the reality," emphasizing that the United States remains Israel's only powerful ally and that the deal was necessary to avoid a global economic catastrophe.[3]

Meanwhile, the maritime industry is navigating the newly reopened waters with cautious optimism. While US Central Command confirmed the cessation of blockade enforcement, tanker operators remain wary of the estimated 80 mines that still need to be cleared from the central route of the Strait.[6]

Furthermore, the long-term status of the Strait remains contested. The memorandum stipulates that Iran must ensure toll-free passage for commercial vessels for the next 60 days. However, Iranian Parliament Speaker Mohammad Bagher Ghalibaf has publicly stated that Iran intends to charge "service fees" once the fee-free period expires.[4][8]

The 60-day negotiation window will also address a proposed $300 billion regional fund for Iran's reconstruction and economic development. The US has indicated it will not directly invest in the fund, leaving the financial burden to regional partners and private investors—a prospect that remains highly uncertain.[6][7]

The most critical unresolved issue is Iran's nuclear program. The memorandum freezes Iran's nuclear weapons development, but Tehran has yet to agree to ship out its stockpile of highly enriched uranium, which is reportedly buried under the rubble of previous US military strikes.[5][6]

The International Atomic Energy Agency (IAEA) has welcomed the interim deal, with Director General Rafael Mariano Grossi stating that the "technical work can start for real." However, verifying Iran's compliance will require unprecedented access to its nuclear facilities, a persistent sticking point in past negotiations.[3]

As the 60-day countdown begins, the global economy has received a vital lifeline. Yet, the delayed Swiss talks and the ongoing friction over Lebanon underscore the fragility of the ceasefire. The path from an interim memorandum to a permanent peace agreement remains fraught with geopolitical landmines.[1][2]
