TOKYO/ISTANBUL - Turkey’s main stock index finished in negative territory on Monday, driven by weakness in several cyclical sectors. At the close in Istanbul, the BIST 100 dropped 0.57%, settling at a level described as a new 1-month low.

The session’s sectoral performance showed losses concentrated in Metal Products & Machinery, Real Estate Investments and Technology, which collectively pulled the benchmark lower.

Risks

  • Market breadth was skewed toward decliners - 343 stocks fell versus 260 advancers - indicating pressure across individual names and sectors.
  • Rising crude and Brent prices could influence market sentiment for energy-exposed companies given the recorded increases in oil contracts.
  • Movements in key exchange rates - USD/TRY up and EUR/TRY down - introduce currency-related volatility for Turkish-listed firms and investors.
