U.S. and Iranian negotiators have paused indirect talks in Doha following the death of Iran’s supreme leader, Ayatollah Ali Khamenei. While mediators report “positive progress” on an interim agreement, significant friction remains regarding shipping tolls in the Strait of Hormuz, nuclear site inspections, and the implementation of a $6bn frozen funds transfer.
Status of the 60-Day Negotiation Window
The diplomatic timeline remains a core point of contention. Under a memorandum of understanding (MoU) signed on June 18, both nations committed to negotiating a final deal within a “maximum 60 days, extendable with mutual consent,” according to CBS News. However, whether the clock started at the signing or began with the first technical meeting remains unclear.
The 60-day window is a standard mechanism in high-stakes regional diplomacy, intended to create a sense of urgency for both parties while allowing domestic stakeholders time to review potential concessions. However, the unexpected passing of the Supreme Leader introduces a period of political transition in Tehran, which historically complicates the continuity of diplomatic commitments. In the Iranian system, the Supreme Leader holds ultimate authority over foreign policy and the nuclear program. Consequently, the pause in Doha is viewed by international observers as a necessary cooling-off period to determine how the new leadership will approach existing agreements.
Eric Lob, a nonresident scholar in the Carnegie Middle East Program, suggests that a compressed timeline benefits Tehran. By formalizing control over the Strait of Hormuz sooner, Iran stands to reap financial benefits while navigating its internal economic challenges.

Tensions Over the Strait of Hormuz
The Strait of Hormuz has become the primary theater for both military and economic posturing. While the interim deal theoretically prohibits Iran from collecting passage fees for 60 days, AP News reports that Tehran continues to insist on its right to dictate vessel routes and impose charges. This stance directly challenges international norms for the waterway, which historically handled one-fifth of global oil and natural gas traffic. The Strait is a vital “chokepoint” in international maritime law; under the United Nations Convention on the Law of the Sea (UNCLOS), transit passage through international straits is meant to be unimpeded, a principle the U.S. Navy maintains by conducting Freedom of Navigation operations in the region.
Recent incidents underscore the volatility. Iranian state media reported that a foreign container ship ran aground this week after using a path not authorized by the Islamic Revolutionary Guard Corps. The Guard has warned that “any entry or exit through routes other than the ‘Route of Authority’ in the Persian Gulf could lead to irreparable incidents.” This rhetoric serves to assert Iranian sovereignty over the waterway, a long-standing goal of the Revolutionary Guard, which often views the presence of international shipping as an encroachment on its territorial waters.

Despite these frictions, commercial traffic is showing signs of recovery. Al Jazeera notes that data from Kpler indicates commercial ship movements through the strait rose by more than 50 percent in the week of June 22–28 compared to the previous week. Iran International adds that while transit numbers remain below pre-war levels—which saw roughly 130 vessels daily—at least 258 ships passed through the waterway last week, a significant increase from 138 the week prior. This fluctuation in shipping numbers highlights the extreme sensitivity of the global energy market to regional instability, as insurers often raise premiums or reroute vessels at the first sign of conflict.
Financial Disputes and Nuclear Oversight
Technical discussions in Doha also addressed the status of $6bn in frozen Iranian funds. These funds, held in restricted accounts, are subject to complex regulatory frameworks that require oversight to ensure they are used strictly for humanitarian purposes, such as food and medicine. Iranian Deputy Foreign Minister Kazem Gharibabadi stated that meetings with Qatari officials focused on the expenditure of these funds, specifically for the purchase of needed goods. The two sides have agreed to establish a communication channel to manage such disputes moving forward, reflecting the need for a neutral third party to verify that financial releases do not violate international sanctions regimes.
The nuclear file remains largely stalled. The International Atomic Energy Agency (IAEA) typically requires continuous monitoring of centrifuges and uranium stockpiles to ensure compliance with non-proliferation standards. While IAEA chief Rafael Grossi has maintained that inspectors must gain access to nuclear sites, Iranian Speaker Mohammad Bagher Ghalibaf recently denied that the agency has been granted such reach. Ghalibaf asserted that current access is limited to the Bushehr power plant and the Tehran reactor, citing parliamentary law and Supreme National Security Council resolutions. This disagreement highlights the ongoing tension between Iran’s domestic legislative mandates and its obligations under international nuclear safeguards.
Diplomatic Outlook Following the Funeral
Negotiations are currently suspended for the funeral of Ayatollah Ali Khamenei, which begins Saturday in Tehran. U.S. Mideast envoy Steve Witkoff and Jared Kushner remain engaged in the mediation process alongside Qatari and Pakistani officials. Qatari Foreign Ministry spokesman Majed al-Ansari confirmed that the parties have agreed to resume discussions “at the earliest possible time” following the mourning period. The involvement of Qatari and Pakistani diplomats indicates the regional reliance on intermediaries who maintain communication lines with both Tehran and Washington, a common feature in diplomatic efforts where direct contact is limited or absent.
With the nuclear issue, the future of the Strait of Hormuz, and the war in Lebanon still unresolved, the next round of talks will likely test the durability of the current interim framework. As Vice President JD Vance indicated to reporters, the U.S. remains focused on the nuclear file as a critical, yet-to-be-negotiated priority. The stakes remain high for all parties involved: for the U.S., the goal is regional stability and the prevention of nuclear proliferation; for Iran, the priority is the lifting of economic sanctions and the assertion of regional influence amidst a sensitive leadership transition.
