According to evaluations by economist Burak Arslan, Borsa Istanbul lost 15 percent of its value due to a sell-off wave in the markets during October 2026, while deposit interest provided a return of 0.39 percent based on inflation-adjusted data.

Driven by volatility in global markets, Borsa Istanbul experienced value losses of up to 15 percent in October. Considered safe havens, gold fell by 5.57 percent, the euro by 3.53 percent, and the US dollar by 0.95 percent, disappointing investors.

Arslan stated that resistance levels of 12,000 and 12,500 should be monitored in the short-term technical outlook of the BIST 100 index.
