BIST 100 Erases Early Losses to Close at 14,405
On September 8, 2026, the BIST 100 index demonstrated resilience by recovering from an intraday drop of 0.35% to close up 1.79% at 14,405.25 points. The rally followed a strong previous session where the index had gained 0.99% to reach 14,151 points, marking a positive start to the week for Turkish equities. This upward movement contrasts with broader emerging market trends, where foreign investors have been net sellers in many Asian markets.
Argentina's Country Risk Drops Below 500 Points
Argentina's market sentiment improved notably during the first week of September, with the JP Morgan EMBI+ country risk index falling to 490 points by September 5, breaking below the 500-point barrier for the first time in recent weeks. The S&P Merval index surged over 2%, reclaiming the 3 million point level, while dollar bonds averaged a 1% gain. Although a minor correction occurred on September 7 due to US holiday closures, with Merval dipping 0.5%, the overall trend remained positive compared to August's poor performance.
Pakistan KSE-100 Suffers Sharp Decline
The Pakistan Stock Exchange (PSX) witnessed significant volatility, with the benchmark KSE-100 index losing 1,692.74 points on Monday, September 7, 2026. This bearish trend followed a brief rally earlier in the week where the index had seen gains of up to 950 points on Thursday, September 3. Local media reported that the index broke below the psychological level of 175,000 points during trading sessions, reflecting sustained selling pressure.
Lira Depreciation Hits New Highs Against Dollar
Turkish financial markets are grappling with currency weakness, as the Turkish lira depreciated to new record lows against the US dollar and euro in early September 2026. This depreciation is occurring alongside heightened geopolitical tensions in the Middle East, which are influencing investor sentiment and central bank policy expectations. Despite the currency's slide, the BIST 100's recent rally suggests that local equities may be acting as a partial hedge for domestic investors.
Local view
Local Turkish financial media, particularly BorsaninGündemi, highlighted the divergence between foreign investor behavior and local market performance. Reports indicate that foreign investors were net sellers in 27 stocks within the BIST 30 index last week, while buying only in three stocks. However, İş Yatırım reports suggest that foreign interest remains concentrated in specific high-liquidity stocks, keeping certain sectors buoyant despite overall outflows. In Pakistan, Business Recorder and Dawn noted that the sharp decline in KSE-100 was driven by global risk-off sentiment and local liquidity constraints.
