Turkey: MSCI Review Triggers BIST 100 Slide Below 12,000

On October 16, the BIST 100 index closed down 2.89% at 11,721.72 points, marking a significant break below the 12,000-point threshold. The decline was driven by news that MSCI is increasing scrutiny on Turkish markets due to a stock fixing scandal, raising fears that Turkish companies could be frozen out of global emerging market indexes. This development has pushed the index to its lowest dollar-basis level in 16 months, with local media reporting heavy selling across banking and holding sectors.

Argentina: Country Risk Hits 2026 High Amid Bond Sell-Off

Argentina’s financial markets faced a tough week, with the country risk index (EMBI) rising to 648 basis points on October 16, its highest level of 2026. The S&P Merval index fell 0.4% on Friday, while "hard dollar" public titles dropped 1.5%, reflecting investor anxiety over sovereign debt sustainability. The Central Bank of Argentina (BCRA) intervened by purchasing USD 68 million in the market, but the risk premium has increased significantly over the last three months.

Pakistan: KSE-100 Breaks 168,000 Points

In contrast to Turkey and Argentina, Pakistan’s stock exchange showed resilience, with the KSE-100 index closing at 168,580 points on Friday, October 16. The index had earlier surpassed the 166,000-point mark during the week, driven by positive buying trends and market optimism. This performance highlights a divergence in frontier market trajectories, with Pakistan benefiting from different local economic dynamics compared to the turmoil in Turkish and Argentine markets.

Israel: TA-35 Mixed as Shekel Hits Semi-Annual High

The Tel Aviv Stock Exchange (TASE) experienced mixed results on October 15, with the TA-35 index dipping slightly by 0.1%. Notably, the real estate index rose 1.8%, while semiconductor stocks declined. The Israeli shekel weakened significantly against the dollar, with the official rate set at 3.1 shekels, marking a semi-annual high for the US currency.

Local view

Borsaningundemi.com reported that the MSCI decision created a wave of selling that lasted throughout the trading day, with the BIST 100 closing at 11,721.72 points. The outlet emphasized that the "freezing" decision on Turkish stocks by MSCI has intensified pressure on local liquidity.

Infobae highlighted that the rise in Argentina’s country risk to 648 points was the sixth consecutive day of increases, driven by global market weakness and specific concerns over local bond valuations. The publication noted that despite the BCRA's currency purchases, the risk premium remains stubbornly high.

TheMarker focused on the currency impact in Israel, noting that the dollar’s strength against the shekel is causing shifts in sector performance, with real estate gaining while tech sectors faced corrections.
