Breaking! IHSG crashes 4.11%, plunging to its lowest level in a year

Jakarta, CNBC Indonesia — The Jakarta Composite Index (IHSG) slumped again significantly in today’s trading, Tuesday 19 May 2026. At the start of the second session the IHSG was down 4.11%, or 270.91 points, to 6,328.28, with market capitalisation dropping Rp 415 trillion versus yesterday to Rp 11,137 trillion.

This marked the lowest level for the IHSG in more than a year.

A total of 661 issuers finished in the red, 80 were unchanged, and 74 rose. The value of transactions reached Rp 17.72 trillion, with 33.36 billion shares changing hands across 2.04 million trades.

Today’s sharp correction extended the weakness seen in yesterday’s session. On Monday, the IHSG fell more than 4%, but managed to trim the decline to -1.85% at the close.

Quoting Refinitiv, nearly all sectors were in the red, with the health sector as the exception. Materials fell the most, by -8.4%, in line with a sharp correction in shares of Prajogo Pangestu’s firms.

Ekamas Mora Republik (MORA) slid 11.41% to weigh on the index with a contribution of -13.45 points. It was followed by Chandra Asri (TPIA) -11.16 points, Amman Mineral (AMMN) -10.63 points, Bank Central Asia (BBCA) -9.37 points, and Dian Swastatina Sentosa (DSSA) -9.26 points.

For information, three of the four five companies mentioned were among those dropped from the MSCI index.

The biggest pressure on the IHSG since the weekend stemmed from shares removed from the MSCI Global Standard Index and the MSCI Global Small Cap Index.

The IHSG’s pressure was further compounded by a weakening rupiah. The rupiah even breached a new psychological level.

Referring to Refinitiv data, as of 12:49 WIB, the rupiah had weakened 0.51% to Rp17,730 per US$.

This weakness persisted after the rupiah opened weaker this morning. At the opening, the rupiah stood at Rp17,650 per US$, or down 0.06%.
