Borsa Istanbul's BIST 100 Falls Over 2% Amid Middle East Tensions and Global Market Uncertainty

Turkey's BIST 100 index closed down 2.12%, ending at 14,189.96 points, a loss of 307.42 points on a trading volume of 200.8 billion lira. The banking sector fell 3.25%, holdings slipped 1.90%, and transport shares dropped 4.38%, while the information‑technology index was the only sector to rise, up 0.30%.

The slump was largely attributed to President Donald Trump's statements that the Iran cease‑fire had ended and that a severe military response was likely, heightening geopolitical risk in the Middle East. Investors also reacted to broader market cues, including the upcoming release of the U.S. Federal Reserve’s meeting minutes and data releases from China, the United States, Japan and Germany.

Additional context came from the 36th NATO summit in Ankara, where allies announced defense supply agreements totaling over $50 billion, and from the International Monetary Fund’s revised World Economic Outlook, which lowered the global growth forecast for 2024 to 3 % and projected Turkey’s growth at 2.9 % this year and 3.6 % next year. Analysts note technical support for the BIST 100 around the 14,100‑14,000 level and resistance near 14,200‑14,300.
