Middle East tensions dominate
Sentiment was weighed down by an escalating conflict in the Middle East after Houthi missile and drone attacks on Saudi Arabia continued on 12 October 2026. At least 13 people were reported killed and more than 300 injured in the attack.
Iran offered to mediate, while Donald Trump was reportedly considering US involvement in retaliatory strikes on the Houthis, though no US military operations had begun. Oil prices climbed on the news: Brent settled at $106.65 a barrel, up $1.93 or 1.8 percent, its highest level since 15 September, while WTI closed at $93.74, up $1.89 or 2 percent.
MSCI downgrade risk lingers
Desy Erawati, analyst at Phintraco Sekuritas, said market issues were still related to MSCI, pointing to investor concern that Indonesia could be downgraded from emerging to frontier market status. Investors are also awaiting the lifting of a freeze on index changes, which is projected for the second half of 2027.
