Will the US and Iran reach a Hormuz deal by December 31, 2026?

The US insistence on linking Hormuz to the nuclear file, and Iran's demand for broad sanctions relief, makes any agreement impossible.

Negotiations fail if Iran demands sanctions relief or nuclear concessions that Washington will not exchange for commercial shipping guarantees.

Disagreement over seizures, inspections, armed escorts, and responsibility for incidents could prevent governments from accepting the same operational terms.

Mutual distrust is so high that neither side will believe the other will honor the terms of a deal, particularly regarding verification and dispute resolution.

Both sides will avoid a major confrontation through tacit, deniable de-escalation measures, making a formal, politically costly deal unnecessary.

Negotiators cannot separate shipping guarantees from sanctions relief and nuclear demands, preventing acceptance of a qualifying agreement by the deadline.

Tacit understandings or parallel unilateral measures could improve shipping security without the matching public confirmations required for a Yes resolution.

Coalition escorts, regional agreements, or a multilateral framework could address transit risks without producing a qualifying new US–Iran bilateral agreement.

Leadership red lines, distrust, or disagreement over maritime implementation prevent the matching public acceptance required for a yes outcome.

A limited agreement focused solely on ensuring freedom of navigation for commercial shipping, in exchange for specific, narrow sanctions relief, could be achieved.

A limited exchange of commercial noninterference, incident procedures, and bounded concessions could secure matching public acceptance without settling the nuclear dispute.

The parties reduce maritime risks through indirect understandings or unilateral restraint but never publicly accept the same bilateral shipping agreement.

A shipping shock raises freight, insurance, and energy costs, prompting commercial and regional pressure that makes a narrow bilateral compromise more attractive.

A limited, unintended military clash or major shipping disruption will scare both sides into making the necessary concessions for a deal.

Reciprocal commercial-shipping guarantees and limited, reversible concessions create an acceptable deal without a comprehensive nuclear settlement.

Sustained shipping disruption raises economic and security costs enough for both governments to accept a limited, publicly acknowledged Hormuz arrangement.

A leadership-level breakthrough could bundle shipping with sanctions or regional security, overcoming obstacles that incremental talks cannot resolve.

Progress on a larger deal (e.g., a renewed JCPOA) will build enough trust and momentum to allow for a supplemental Hormuz agreement.

China, with its significant economic and diplomatic leverage over Iran, will step in to broker a Hormuz agreement to secure its own energy imports.
