President Donald Trump threatened on Saturday to impose tolls on vessels transiting the Strait of Hormuz, one of the world's most critical oil shipping chokepoints, if the United States and Iran do not finalize a nuclear agreement within 60 days. The ultimatum adds significant economic pressure to ongoing diplomatic negotiations between the two countries.

Vice President JD Vance was present in Switzerland as part of the diplomatic effort to reach a deal, underscoring the administration's continued engagement with Iranian counterparts despite the escalatory threat. The talks represent the most sustained high-level diplomatic contact between Washington and Tehran in years.

The Strait of Hormuz carries roughly one-fifth of the world's oil supply, and any disruption or imposition of tolls on shipping lanes there would have immediate and far-reaching consequences for global energy markets. Analysts have noted that the legal and practical mechanisms for enforcing such tolls remain unclear under international maritime law.

Inside Iran, the political environment is under increasing strain. Protests have intensified in recent weeks, with citizens publicly demanding an end to Ayatollah Khamenei's rule. The domestic unrest adds another layer of complexity to the negotiations, as Iranian leadership faces simultaneous external pressure from Washington and internal dissent at home.

Polling cited by some outlets suggests the prospect of a Trump-brokered Iran deal enjoys broad public support in the United States, which the administration has pointed to as political backing for its aggressive negotiating posture. Whether the 60-day deadline will accelerate an agreement or harden positions on both sides remains to be seen.
