[96913] Wave of Declines on the Istanbul Stock Exchange: Fed Interest Rate Impacts and Geopolitical Tensions

A Gloomy Trading Day on the Istanbul Stock Exchange: Broad-Based Declines Across All Sectors

Tuesday, June 23, 2026, was marked by significant selling pressure on the Istanbul Stock Exchange. According to data from Borsa Haber 🔔 and ÖNE ÇIKAN HİSSELER GÜNDEM, the BIST 100 index recorded a daily decline of 1.29% and closed at 14,539.61 points, with the daily trading volume reaching 224 billion Turkish Lira.

The factors for the declines are primarily attributed to market assessments that the Federal Reserve (Fed) may continue its high-interest-rate policy into next year. As reported in 𝐁𝐎𝐑𝐒𝐀 𝐆𝐔𝐍𝐃𝐄𝐌𝐈, "expectations that the Fed will maintain a hawkish stance are strengthening the dollar and weighing on the markets." Despite positive diplomatic developments between the US and Iran that led to a drop in oil prices, the general sentiment remains negative, with the crypto market also experiencing volatility as Bitcoin fell below $63,000, as noted in Cloud Kripto.

A Bank of America analysis, as published in 𝐁𝐎𝐑𝐒𝐀 𝐆𝐔𝐍𝐃𝐄𝐌𝐈, showed dominant selling flows among financial institutions, with a net selling volume of 946.4 billion Lira. Stocks such as ASTOR and TRALT recorded sharp declines, while investors are looking for direction ahead of the second-quarter 2026 earnings reports. At the same time, İPEK ARDIÇ İLE GÜNDEM highlighted that the market is now focusing on announcements regarding capital increases and dividends, especially in stocks like HRKET and HLGYO.

The atmosphere in the markets was described in 𝐁𝐎𝐑𝐒𝐀 𝐆𝐔𝐍𝐃𝐄𝐌𝐈 as extremely pessimistic: "Gold is down, oil is down, the crypto market has crashed, the stock exchange is down - there is nothing that isn't falling." Sources in Gündem Hattı explain that rising bond yields and the strengthening of the dollar are creating heavy pressure on all assets, with the Fear and Greed Index in the crypto market sitting at 23/100, which indicates 'extreme fear'.
