FTSE Indexes Retreat as Geopolitical Strains Reemerge

The FTSE 100 shed 1.3% to close at 10,519.17 points by 1111 GMT, marking its lowest valuation in nearly seven days. The midcap FTSE 250 index suffered a deeper blow, tumbling 1.7% to hit a one-week low. This synchronized decline underscores a broader retreat from risk as markets react to the sudden hardening of U.S. policy toward Tehran.

Institutional anxiety remains centered on the potential for energy market disruption. With diplomatic channels stalled, traders are pricing in the risk of supply chain instability, pushing capital toward safer assets and away from blue-chip equities. The sharp drop across both major indices reflects a widespread reassessment of economic exposure to Middle Eastern instability.
