The United States and Iran have reached a tentative interim agreement to end their conflict and reopen the Strait of Hormuz [1].

The deal aims to restore the free flow of crude oil through one of the world's most critical maritime chokepoints [2]. Because the region's stability directly impacts global energy costs, the news triggered an immediate reaction across international financial markets [1].

Oil prices fell by more than $1 per barrel following the announcement [3]. The drop reflects a reduction in the risk premium that traders apply when wartime disruptions threaten the global supply of oil [2].

Equity markets responded with widespread gains. The TSX composite index rose more than 300 points as investors reacted to the prospect of decreased geopolitical tension [4]. While some reports describe the stock market rally as worldwide [1], other analysts said that the jump on Monday was only moderate [5].

Diplomatic efforts to finalize the arrangement have centered on Switzerland. While some reports indicated the interim agreement was signed on Thursday [3], other accounts said that officials were scheduled to meet in Switzerland on Friday to sign the initial document [2].

President Donald Trump represented the U.S. in the negotiations to halt hostilities [1]. The agreement focuses on ending the immediate war and ensuring that shipping lanes remain open to prevent further spikes in energy costs [2].

The United States and Iran have reached a tentative interim agreement to end their conflict.

The agreement signals a pivot toward stabilization in the Middle East, which reduces the immediate threat of an energy crisis. By reopening the Strait of Hormuz, the U.S. and Iran are easing the pressure on global supply chains, though the tentative nature of the deal suggests that long-term economic stability depends on the successful implementation of the full diplomatic framework in Switzerland.
