Vietnam: VN-Index Breaks 1,800 Support Amid Foreign Outflows
On September 11, the VN-Index dropped over 34 points to close below the 1,800-point milestone at 1,795.21 points. This decline was driven by intense selling pressure from both domestic and foreign investors, with foreigners net selling approximately 870 billion VND (approx. $35 million) on that day alone. The move contradicts earlier optimism surrounding Vietnam's upcoming upgrade to secondary emerging market status by FTSE Russell, which takes effect on September 21, 2026.
Indonesia: IHSG Suffers Heavy Weekly Net Sell by Foreigners
The Jakarta Composite Index (IHSG) faced significant pressure throughout the week ending September 11, with foreign investors recording a net sell of Rp3.36 trillion ($191.3 million). On September 10, the IHSG fell 1.29% to close at 6,591.90, with foreigners dumping Rp1.95 trillion worth of shares in a single session. Bank Central Asia (BBCA) was the most heavily sold stock during this period.
Thailand: SET Index Drops on Middle East Geopolitical Concerns
Thailand's SET Index closed at 1,604.52 points on September 11, down 10.55 points (-0.65%), as investors reduced risk exposure due to escalating hostilities in the Middle East. Foreign investors were net sellers of 2.04 billion baht on the SET and MAI markets during the reporting period. The total trading value for the day stood at 71.2 billion baht.
Local view
Local Vietnamese media outlets such as Dân Trí and Tiền Phong have focused heavily on the disconnect between the anticipated FTSE Russell upgrade and the current foreign capital outflows. Dân Trí highlighted that despite the upgrade confirmation, foreign investors have net sold over 90 trillion VND year-to-date, raising questions about the immediate impact of the reclassification. In Indonesia, CNBC Indonesia reported that while the broader market fell, foreign funds selectively accumulated shares in specific sectors, including banking, with BRI seeing notable net buys despite the overall negative sentiment.
