MSCI Remains the Main Trigger

Selling pressure continues on investor fears over Morgan Stanley Capital International's (MSCI) consultation on a possible downgrade of Indonesia's stock market classification from emerging market to standalone market. Global sentiment added weight too, from US inflation worries and the direction of Fed rates to rising world crude prices and Middle East geopolitical tensions.

On Friday (Oct 16, 2026), the JCI closed down 678.77 points, or 11.57 percent, at 5,185.10 — after triggering a 30-minute trading halt following an 8 percent early-session plunge. Over the week, the index corrected 14.91 percent, wiping about Rp1,544 trillion off Indonesia Stock Exchange market capitalization.

Meanwhile, the rupiah in the spot market opened marginally stronger, up 0.006 percent to Rp18,026 per US dollar, compared with Friday's close at Rp18,027.

Takeaway

The breach of the 5,000 level at the start of the week marks selling pressure that has yet to ease after the MSCI downgrade threat. Investors will watch developments on Indonesia's market classification and regulators' moves to calm the turbulence in coming sessions.
