US stock markets opened higher on Monday, driven by a diplomatic breakthrough between Washington and Tehran.
The two nations have agreed to halt their recent military attacks and return to negotiations, marking a significant de-escalation in tensions that have persisted for days.
The agreement to end hostilities provided immediate relief to investors who have been pricing in elevated geopolitical risk.
With the threat of further military escalation receding, risk appetite returned to the session, lifting major indices at the open.
The development follows a period of heightened volatility as markets assessed the potential for broader conflict in the region.
This shift in tone comes after weeks of uncertainty regarding the US-Iran relationship.
