The Athens Stock Exchange experienced a significant downturn as military strikes on Iran's largest natural gas field reignited investor concerns, even after a positive start to the day. The Brent crude oil prices surged close to $110 per barrel, pushing traders to limit exposure to high-risk assets. As a result, European stocks quickly lost their initial gains and turned negative, with the Wall Street also opening with a decrease of approximately 1%.

Market attention has shifted toward the anticipated decisions by the Federal Reserve regarding U.S. interest rates later today. Analysts, wary of a new inflationary wave affecting the global economy, view the chances of an immediate reduction in borrowing costs as virtually nonexistent. This potential shift in U.S. monetary policy adds another layer of uncertainty to an already volatile market environment.

In this backdrop, the General Index of the Athens Stock Exchange not only erased all intraday gains, which had reached up to 1.8%, but also closed with losses, marking a decline of 0.62% to settle at 2,129.8. This development reflects growing apprehension among investors regarding geopolitical tensions and economic indicators, as they grapple with the implications of rising oil prices and inflationary pressures on the market.
