Tensions Rise in Strait of Hormuz Amid U.S.-Iran Technical Talks in Switzerland

Tensions between the United States and Iran escalated over the last 24 hours as Tehran announced a strategic order to close the Strait of Hormuz. Iranian state media framed the move as a direct response to Israeli military activity in Lebanon. However, U.S. Central Command (CENTCOM) dismissed the claim of a blockade, stating that Iranian forces do not control the waterway. Saturday’s maritime data showed 55 merchant ships successfully transited the strait, carrying over 17 million barrels of oil, while U.S. forces continue active monitoring to ensure open passage. On the diplomatic front, high-level technical talks have resumed in Switzerland with the goal of refining an interim nuclear framework. Vice President JD Vance joined top U.S. negotiators Jared Kushner and Steve Witkoff in Switzerland on Saturday evening to meet with Iranian envoys. These discussions, mediated by Pakistan and Qatar, had been briefly delayed after Tehran initially pulled back due to the regional escalation in Lebanon. The nuclear file is now increasingly linked to proxy violence, with the 60-day negotiating window set by Washington remaining the primary deadline. President Trump has added a new economic dimension to the standoff, threatening to implement U.S.-managed 'tolls' for ships passing through the Strait of Hormuz if a final agreement is not secured within the 60-day period. This potential shift toward a fee-based maritime regime accompanies an intense internal debate in Tehran, where hardline factions are pressuring negotiators to use the threat of a maritime blockade as leverage against American demands regarding enrichment and verification.
