Free Fall in Borsa Istanbul; Simultaneous Crash of 60 Stocks and Gold Market Turbulence

Earthquake in Istanbul's Glass Hall; Mass Stock Crash On the first day of July 2026, Borsa Istanbul (BIST) witnessed one of the most severe selling waves in recent months. According to a report by the economic media outlet Haber 7, the prices of more than 60 index stocks plummeted sharply within short intervals, leading to the frequent activation of circuit breakers for many tickers [1]. The BIST 100 index, which had reached the 14,121 level at the end of yesterday's trading, came under heavy selling pressure today, losing many of its gains from recent weeks [3].

Unprecedented Fluctuations in the Gold and Dollar Markets Simultaneously with the crisis in the capital market, parallel markets also experienced a tense day. The price of the Dollar in Turkey's free market penetrated the 46.70 Lira range, indicating continuous pressure on the national currency. Meanwhile, the global price of gold surpassed the $4,020 per ounce mark, affecting Turkey's domestic market and pushing the price per gram of gold to unprecedented levels [2]. Experts believe that this "shifting of stones" in the gold, dollar, and stock markets stems from investor fears regarding escalating geopolitical tensions in the region and sudden changes in monetary policies [1].

Crisis Drivers; From Regional Tensions to the End of the Short Selling Ban Analysts cite several key factors for this sudden decline. First, the escalation of conflicts in the Middle East, which has led to the exit of foreign capital from emerging markets. Second, the recent decision by the Capital Markets Board of Turkey (CMB) to end the ban on "Short Selling," which took effect on June 29, has increased technical selling pressure on large-cap stocks [2]. This ban, previously imposed to control war-related volatility, has now been lifted, opening the way for bearish traders.

Structural and Technical Changes in Borsa Istanbul Despite the market turbulence, Borsa Istanbul also saw the implementation of important technical changes today. As of July 1, 2026, the exchange's new data center officially began operations with the aim of increasing transaction speed and capacity [4]. Additionally, the revision of stock indices and the relocation of several large companies between the "Star" and "Main" indices took effect today, which itself has been a factor in the rebalancing of portfolios by large investment funds and increased trading volume in specific tickers [4].

Market Outlook in the Coming Days Given the current situation, analysts recommend that retail shareholders avoid emotional behavior. Although the stock index is at the 14,000-unit support level, continued fluctuations in the currency and gold markets could prevent a rapid recovery of prices. It is expected that upcoming meetings of the Central Bank of the Republic of Turkey and the release of June inflation statistics will determine the market's next direction [3].
