Borsa Istanbul Closed the Week — Here’s What Moved Markets

Borsa Istanbul wrapped up another turbulent week as investors balanced domestic inflation expectations against global risk appetite. The BIST-100 index saw intraday swings driven by foreign investor positioning, currency volatility, and shifting sentiment around the Central Bank's next policy move. Trading volumes told a story of hesitation rather than conviction.

The week's performance matters because Borsa Istanbul is no longer just a local story. With foreign ownership of Turkish equities at historically low levels, even modest re-entry by international funds can move the index sharply. Domestic retail investors, who have flooded the market since 2021 as an inflation hedge, are now watching their paper gains more carefully as real returns come under pressure.

For anyone holding Turkish stocks — whether in a pension fund or a personal brokerage account — last week was a reminder that direction here is rarely clean. Banking stocks, industrials, and export-heavy names each told a different story depending on where the lira moved. The week closed with more questions than answers about whether the current index levels reflect fundamentals or just momentum.

Levent KAYIRA Commentary: Ekonomik Gündem Analysis: From my years running portfolios at Garanti and Denizbank, I can tell you that weeks like this one separate disciplined investors from noise-chasers. BIST-100 has been trading in a band that reflects a tug-of-war: domestic inflation running hot keeps equities attractive as a store of value, but 40%+ interest rates mean the opportunity cost of holding stocks is no longer trivial.

Bank stocks deserve special attention. Turkish lenders are reporting strong nominal earnings, but strip out inflation and the picture gets murkier. Price-to-book ratios look cheap on paper — some majors trading near 1x — but that only means something if you believe loan quality holds through the next rate cycle.

Export-oriented industrials remain the most honest trade on this board. A weaker lira mechanically boosts their revenues in local currency terms. If you're a small business owner with savings in equities, these names offer a partial natural hedge against currency depreciation.

Bottom line: last week's Borsa Istanbul action was a consolidation, not a breakout. Until the Central Bank signals a clear easing path with credible inflation data behind it, expect more of the same sideways grind.
