Iran announced that technical-level talks with the U.S. regarding a final nuclear deal will begin this Sunday, June 21 [1].

This simultaneous push for diplomacy and escalation of maritime restrictions creates a volatile environment for global energy markets and regional security. The move signals Iran's strategy of using economic leverage to secure better terms for sanctions relief.

Foreign Minister Abbas Araghchi said the upcoming negotiations will address the core components of a permanent agreement. "In the final agreement, decisions will be made on the nuclear issues and the lifting of sanctions," Araghchi said [2].

Despite the scheduled diplomatic engagement in Switzerland, Iran has closed the Strait of Hormuz [3]. The closure serves as a protest against Israeli attacks in Lebanon and is intended to pressure the U.S. over the existing interim nuclear agreement [3, 4].

Reports on the stability of the diplomatic track vary. Some sources indicate that the talks are set to start Sunday [1], while others suggest the meetings in Switzerland are unlikely to happen due to the current obstacles [4].

The Strait of Hormuz remains one of the world's most critical chokepoints for oil transit. By restricting access, Iran demonstrates its ability to disrupt global trade to achieve political concessions in its nuclear negotiations [3, 4].

"In the final agreement, decisions will be made on the nuclear issues and the lifting of sanctions."

The dual approach of pursuing a final nuclear deal while closing the Strait of Hormuz suggests that Iran is employing a 'maximum pressure' tactic of its own. By linking regional conflicts in Lebanon and the security of global oil transit to nuclear negotiations, Tehran is attempting to force the U.S. to offer more comprehensive sanctions relief in exchange for nuclear compliance and maritime stability.
