**It also failed to secure a final nuclear deal by the end of 2026.**

Mojtaba Khamenei remained Iran's top political figure through the end of 2026. No change in the country's leadership occurred during the year. Opposition figure Reza Pahlavi neither entered Iran nor took any governing role in 2026.

Iran did not reach a final nuclear agreement with the United States by October 31, 2026. The nation also failed to agree to end uranium enrichment by the end of the year. It did not surrender its enriched uranium stockpile before December 31, 2026.

Iran did not produce a nuclear weapon before 2027. The government also refrained from imposing fees on ships passing through the Strait of Hormuz by October 31, 2026. No new revenue measures were introduced for Hormuz traffic.

By December 31, 2026, Iran's political hierarchy remained under Khamenei's authority. The nuclear negotiations with the United States concluded without a final agreement. Enrichment activities and the stockpile of enriched uranium persisted unchanged.

The Strait of Hormuz saw no new fee regime imposed by the October deadline. Reza Pahlavi remained outside Iran throughout the year, making no entry by December 31. The overall picture showed no shift in Iran's leadership or nuclear trajectory during 2026.

## Analysis

Without a leadership transition, internal power dynamics and policy priorities are likely to follow established patterns that have characterized recent years.

The absence of a final nuclear deal leaves diplomatic relations between Iran and the United States in a stalemate. Existing sanctions and restrictions therefore remain in place, limiting avenues for economic relief or cooperative security measures.

Iran's unchanged enrichment program and the retention of its enriched uranium stockpile maintain the status quo of its nuclear capability. The lack of a weapon breakthrough reduces immediate proliferation concerns, but the persistent enrichment capacity keeps regional actors alert.

Together, the political and nuclear continuity creates a predictable yet constrained environment. Future shifts will depend on external diplomatic initiatives or internal pressures, both of which remain uncertain as of the end of 2026.
