BIST 100 Ends Week with Mixed Performance as Geopolitical Tensions Linger
The BIST 100 Index at Borsa Istanbul opened the week with a 0.39% decline to 14,265.51 points, only to rebound on Friday with a 1.53% gain, closing at 14,321.19 points. The banking index fell 1.18%, while the holding index lost 0.59%. The chemicals-petrochemicals-plastics sector led gains with +1.10%, whereas the transportation sector lagged with -1.38%.
Global markets faced selling pressure due to escalating geopolitical risks, including potential U.S. military action against Iran and ongoing tensions in the Hormuz Strait. Domestic investors turned their attention to the upcoming May Payments Balance data from the Central Bank of the Republic of Turkey (TCMB). According to AA Finance's survey, economists expect the current account deficit to reach $1.1275 billion in May, projecting a full-year deficit of $52.255 billion.
Analysts noted that the BIST 100 technical support levels are at 14,100 and 14,000 points, with resistance at 14,400 and 14,500 points. Domestic focus remains on payments balance and retail sales, while international markets await the U.S. federal budget data.
Market performance reflects short-term volatility driven by geopolitical risks, yet sectoral divergence and macroeconomic data will shape future trends. TCMB's upcoming data is likely to influence exchange rates and inflation expectations significantly.
