European stocks posted a second straight monthly gain as markets reacted positively to diplomatic developments. Investors welcomed the potential de-escalation of tensions between major powers, which typically reduces uncertainty and supports risk appetite across global financial markets.

Optimism grew that the US and Iran will extend a ceasefire agreement and resolve their three-month conflict. This geopolitical easing has boosted investor confidence across European bourses, with regional benchmarks showing consistent upward momentum despite broader economic uncertainties.

The sustained market performance reflects how international political developments directly influence trading patterns. European investors particularly sensitive to geopolitical risk factors have responded positively to the prospect of reduced Middle East tensions, potentially supporting continued stability in regional equity markets.
