European equity markets staged a broad-based relief rally on Monday, driven by reports that the United States and Iran have reached a framework agreement to de-escalate tensions in the Middle East.

The pan-European STOXX 600 index rose 0.8% to trade at 649.34, reflecting a swift shift in risk sentiment as investors priced in a reduced probability of supply disruption.

3% to close at 24,956 points, signaling strong conviction among continental investors.

The rally was underpinned by a retreat in oil prices, which fell as the prospect of a sustained pause in U.S.-Iran hostilities alleviated fears of a prolonged supply shock.

Lower energy costs provided immediate tailwinds for European industrials and consumer discretionary sectors, which had been weighed down by elevated input costs in recent weeks.

The German DAX led the charge, rising 1.3% to close at 24,956 points, signaling strong conviction among continental investors.

This development marks a significant pivot from the risk-off environment that characterized the previous trading session, when Indian equities faced downward pressure as oil surged past $95 on reports of U.S. strikes.

The rapid reversal highlights the sensitivity of global markets to geopolitical headlines, with the reported framework agreement serving as a catalyst for a broad-based rotation back into risk assets.

Investors will now focus on the durability of the reported agreement and whether it translates into a sustained decline in crude prices.

Any signs of renewed tension could quickly reverse the current momentum, keeping volatility elevated in the near term.
