Türkiye’s Borsa İstanbul saw a downturn in the first half of Monday’s session, with the benchmark BIST 100 index dropping 67.43 points or 0.63 percent to reach 10,575.17 as of 13.00 local time. The decline followed early gains that briefly pushed the index up to 10,682.32 points, before losses in the banking and mining sectors triggered a pullback.
Total trading volume reached 39.8 billion Turkish lira during the first half of the session, reflecting cautious investor sentiment amid mixed domestic and global economic signals.
Sector Performance Overview
While the banking index suffered a 0.95 percent decline, the holding index managed to edge up by 0.58 percent. Among sectoral indices, the metal main industry sector led gains with a 1.76 percent increase. On the downside, the mining sector experienced the sharpest drop, falling by 5.58 percent.
The early gains in the equity market gave way to selling pressure as traders reacted to weak sector-specific performance and a broader sense of market uncertainty.
Inflation Expectations See Mixed Trends Across Sectors
Data released by the Central Bank of the Republic of Türkiye (TCMB) revealed notable shifts in inflation expectations for July. According to its latest survey:
Market participants revised their 12-month forward inflation expectations down by 1.2 percentage points to 23.4 percent.
The real sector adjusted its forecast downward by 0.8 percentage points to 39 percent.
Household inflation expectations, however, increased by 1.5 percentage points, reaching 54.5 percent.
These figures reflect diverging sentiment across different economic actors, highlighting challenges in managing inflation perceptions and anchoring market expectations.
Technical Outlook for BIST 100
Market analysts stated that attention for the remainder of the day would focus on international indicators, particularly the Dallas Fed Manufacturing Index from the United States. This data may offer fresh insights into global demand trends, which could influence investor positioning in emerging markets like Türkiye.
From a technical standpoint, analysts identified the 10,500 and 10,400 levels as key support zones for the BIST 100 index. On the upside, resistance is expected around 10,650 and 10,750 points. A break above resistance could open the door for renewed momentum, whereas a dip below support might trigger further consolidation.
Mixed Sentiment in Asian Markets
As of July 28, 2025, Asian stock markets displayed a mixed performance. Investors in the Asia-Pacific region are reacting to varying macroeconomic data and central bank signals. This broader uncertainty is also feeding into emerging market dynamics, including Türkiye.
Spotlight Event – Istanbul Commodity Exchange Discusses GMOs
In a related economic forum, the Istanbul Commodity Exchange (İSTİB) hosted a “Borsa Meydanı” panel focused on Genetically Modified Organisms (GDO), exploring their implications for agriculture, food safety, and trade. Such sectoral discussions are increasingly relevant as Türkiye navigates both domestic food security concerns and international export competitiveness.
Conclusion
The BIST 100’s midday decline underscores the volatility that continues to define Türkiye’s equity markets in 2025. With inflation dynamics shifting and investor sentiment fluctuating, market participants are closely watching both local developments and global economic indicators. As the second half of the trading session unfolds, all eyes will be on key technical levels and potential macroeconomic catalysts that could shape short-term market direction.
