Executive Summary

The BIST 100 opened the week near 14,730 and closed at 14,274.02, for a net decline of approximately 3.1%. The path featured modest losses early, sharper drops mid-week, and a small rebound on Friday. Volume remained elevated throughout the five sessions.

Weekly Drivers

  • Global risk sentiment and domestic rate expectations weighed on Turkish equities during the period.
  • Limited company-specific earnings or macroeconomic data releases directly moved the index.
  • Lira stability and foreign investor positioning continued to influence daily flows.

Sectors & Breadth

Financials showed relative resilience in broader monthly commentary, though sector-level detail for the specific week remained limited. Declines appeared broad-based across major constituents, with no single sector dominating the downside. Breadth metrics indicated participation from a wide range of stocks rather than narrow leadership.

What to Watch

  • Central Bank of the Republic of Turkey policy signals and inflation prints scheduled for early July.
  • Any updates on foreign portfolio flows and lira volatility.
  • Global equity and emerging-market risk appetite ahead of key U.S. and European data.

Capital-Flow Context

Recent International Investment Position data showed Turkey’s external liabilities exceeding assets, consistent with ongoing net debtor status. Portfolio flows have exhibited mixed patterns, with periods of foreign buying offset by domestic and global reallocations. Currency effects remain a key transmission channel for equity performance.
