Ilona Estherina, Jakarta – The Jakarta Composite Index (JCI) this week, May 11-13, plummeted by 3.53 percent to 6,723.32, amid the announcement of Morgan Stanley Capital International (MSCI) rebalancing.

Based on the data from the Indonesian Stock Exchange (IDX), the stock index this week dropped from 6,936.39 from the previous week, in line with the decline in market capitalization. "IDX market capitalization also slipped 4.68 percent to Rp11.825 trillion from Rp12.406 trillion in the previous week," as quoted from IDX statement on Thursday, May 14, 2026.

The average frequency, value, and daily transaction volume of JCI this week also declined compared to the previous week. The average daily transaction frequency this week slid by 0.56 percent to 2.53 million transactions from 2.55 million transactions the previous week.

MSCI announced the results of the rebalancing or adjustment on the Indonesian stock index on Wednesday, May 13, 2026. Based on MSCI's latest assessment, six Indonesian stocks were dropped from the Global Standard Index. Then, one stock was added, and 13 stocks were removed from the Global Small Cap Index.

Following the announcement, IDX, PT Kliring Penjaminan Efek Indonesia (KPEI), PT Kustodian Sentral Efek Indonesia (KSEI), and Financial Services Authority (OJK) held a press conference.

They emphasized that domestic stock trading still occurs in a controlled manner without indications of panic selling. The market decline is seen as part of the anticipated global investor portfolio adjustment process, as well as an opportunity since stock valuations become more attractive compared to the beginning of the year.

Acting President Director of IDX, Jeffrey Hendrik, regards the recent MSCI announcement as a positive development that can reduce one of the elements of uncertainty in the market, especially amid the high global volatility due to geopolitical turmoil, commodity price fluctuations, and currency movements.

He hopes that this certainty can become the basis for the future growth of Indonesia's capital market together with all market participants and issuers.
