Indonesian stock market triggers market suspension of trading, prior to which MSCI temporarily suspended certain adjustments related to the index.

At 14:43 Beijing time, the Indonesian stock market plummeted 8% on Wednesday, triggering a trading halt. The reason for this was pointed out by the index provider MSCI, citing lack of transparency in ownership structure and free float data as reasons for investment risks. It was mentioned that trading in the Indonesian stock market will resume in 30 minutes. MSCI stated that if transparency in the Indonesian stock market does not improve by May, it will reevaluate the market's investability for global investors. This reassessment could lower the weight of Indonesian stocks in the MSCI Emerging Markets Index, or even downgrade its status to a frontier market. MSCI also mentioned that investors are "concerned about the possibility of disruptive coordinated trading behavior affecting normal price formation." Meanwhile, MSCI stated that there would be no adjustments related to Indonesia in its indices. The Indonesian Stock Exchange, Securities Registration and Settlement Institution, and financial regulatory authority OJK stated that they are discussing this issue with MSCI. The Corporate Secretary of IDX, Kossar Prima D. Nurahmad, stated: "Prior to this, we have increased transparency by posting free float data announcements on the IDX website. However, if MSCI believes this is not enough, we will continue discussing data transparency issues in accordance with MSCI's recommendations." KSEI and OJK have not immediately responded to requests for comment.
