Borsa Istanbul Met the Holiday with a Decrease; Market Analysis July 15

Market Trend Analysis on the Eve of the Holiday The Turkish capital market experienced volatile days leading up to mid-July 2026. The Borsa Istanbul main index (BIST 100) closed at 14,080.44 points with a slight 0.09% decrease on the last trading day before the public holiday [1]. This downward trend, which began with a sharp 1.60% drop on Monday, indicates trader caution in the face of systemic risks [2].

Influencing Factors: From Geopolitical Tensions to Monetary Policies One of the primary reasons for the selling pressure in the market was reported as increased tensions in the Middle East, particularly around the Strait of Hormuz. This has reduced risk appetite among both domestic and foreign investors [4]. According to reports published in media outlets such as "Canlı Gaste," currency fluctuations and the US Dollar reaching the 47 Lira range have also affected the production costs of industrial companies and overshadowed their profitability [3].

Furthermore, the global gold price, which reached the $4,090 per ounce mark, caused a portion of stock market liquidity to be diverted toward the precious metals market [1]. Meanwhile, to control extreme volatility, Borsa Istanbul was forced to implement the "uptick rule" in short-selling transactions during some sessions [2].

Status of Symbols and Trading Suspension In recent trading, the transportation, leasing, and technology sectors experienced the most significant declines in value. However, some individual stocks in the renewable energy sector, such as "Margun Enerji," managed to move against the market trend with growth of nearly 10% [1]. Highly watched symbols such as Turkish Airlines (THYAO) and Aselsan (ASELS) remained at the top of trading volumes [4].

Today, Wednesday, July 15, 2026, on the occasion of "Democracy and National Unity Day," Borsa Istanbul and all subsidiary financial markets, including VİOP, are closed [5]. Official trading and the settlement process (Takas) will resume tomorrow, July 16. Experts believe that the market reopening on Thursday will largely depend on exchange rate stability and signals received from global markets.
