President Donald Trump rejected an Iranian proposal that would have linked a seven-day truce to the reopening of the Strait of Hormuz and renewed negotiations on Iran's nuclear program. Tehran presented the proposal at the UN General Assembly and sought the release of frozen Iranian funds, the lifting of sanctions, and an end to the US naval blockade of Iranian ports. Trump said he nonetheless expected talks with Iran to resume during the coming week, indicating that diplomatic contact may continue despite the rejection of Tehran's terms.
Iran has maintained that reopening the strait remains conditional on fulfillment of its demands. Foreign Minister Abbas Araghchi said Tehran had communicated a concrete seven-day plan to Washington through Qatar and continued to favor diplomacy, but Iranian officials also stated that they would not retreat from their conditions. Washington's UN ambassador, Mike Waltz, characterized the Iranian proposal as an unacceptable effort to secure sanctions relief, access to frozen assets, and an end to the blockade merely in exchange for returning to negotiations. The two sides therefore remain divided not only over the terms for reopening Hormuz, but also over whether those terms should precede or follow substantive talks.
The dispute has immediate effects on maritime activity and energy markets. Brent crude rose more than 3 percent in Asian trading on September 28, approaching $108 per barrel before trading near $107.35. Commercial transits through Hormuz rose to 132 vessels during September 21-27, from 116 the prior week, but remain far below the roughly 130 daily crossings recorded before the war. Shipping has declined sharply amid attacks on vessels in the Gulf, most of which have been attributed to Iran or Iran-aligned groups. Before US and Israeli strikes on Iran began in late February, about one-fifth of global oil supplies passed through the waterway.
The rejected proposal places the Strait of Hormuz at the center of bargaining between Washington and Tehran. Iran is treating renewed commercial passage as contingent on sanctions, financial, and military concessions, while the United States has rejected that package as too costly and insufficiently credible. This leaves neither side with an obvious interim arrangement that can restore normal shipping while postponing broader disagreements over the war and Iran's nuclear program. The immediate result is a continuation of uncertainty rather than a clear movement toward either settlement or de-escalation.
The market response reflects the significance of even partial disruption at Hormuz. The increase in weekly transit numbers suggests that some vessels are still moving through the strait, but the comparison with prewar traffic shows that commercial activity remains severely constrained. Oil prices are therefore responding not simply to a formal closure, but to the prospect that shipping will remain unreliable and exposed to further attack. Sustained disruption could increase costs for oil purchasers, shippers, insurers, and firms dependent on Gulf energy exports, even if some traffic continues.
Trump's expectation of renewed talks creates a narrow diplomatic opening, but it does not resolve the central sequencing dispute. Tehran's public position is that compliance with its conditions must precede reopening the strait, whereas Washington has indicated that it will not grant broad concessions simply to resume negotiations. This mismatch raises the risk that talks, if they occur, will become a channel for testing positions rather than producing an immediate maritime arrangement. The prospect of further US air strikes, which Trump has raised publicly, also increases the consequences of diplomatic failure.
The most consequential indicators are whether indirect talks materialize, whether either side modifies its stated conditions, and whether vessel movements recover toward prewar levels. A revised Iranian offer that separates shipping access from the larger sanctions and nuclear questions could create room for a limited arrangement, though no such change has been announced. Conversely, continued low transit levels, further vessel attacks, or renewed strikes would reinforce the perception that Hormuz is becoming a sustained coercive pressure point rather than a negotiable element of a broader settlement.
