Turkey’s BIST 100 index fell to around the 10,000 level in October 2025, its lowest since early July, before staging a modest rebound. The benchmark remains well below its record high set in August, as investors continue to weigh political uncertainty and rising inflation pressures. A key focus is the Turkish court ruling on the leadership dispute within the main opposition CHP, scheduled for October 24th. Adding to political tensions, prosecutors have sought authorization from the Interior Ministry to investigate Ankara Mayor Mansur Yavas, another potential challenger to President Erdogan. On the economic front, annual inflation accelerated for the first time in fifteen months, reaching 33.29% in September, though the central bank is still widely expected to deliver a 100 basis-point reduction this week. In corporate news, defense firm Aselsan has soared nearly 200% year to date, reflecting strong performance in the global defense sector, buoyed by rising military budgets worldwide.
