Jakarta. The market capitalization of the Indonesia Stock Exchange (IDX) fell by about Rp 1,160 trillion ($68.6 billion) over the past week as the benchmark index dropped nearly 8%, reflecting global market volatility triggered by military strikes by the United States and Israel on Iran.

During the trading period of March 2–6, the Jakarta Composite Index (JCI) declined to 7,585.6 points, down from 8,235.4 points at the close of the previous week.

The sharp decline also reduced the overall market capitalization of IDX-listed companies by 7.85%, falling to Rp 13,627 trillion ($806.2 billion) from Rp 14,787 trillion ($874.8 billion) a week earlier, according to IDX Corporate Secretary Kautsar Primadi Nurahmad.

Trading activity also weakened during the period. The average daily transaction frequency on the IDX fell 7.33% to 2.73 million transactions, down from 2.95 million in the previous week.

“The average daily trading value on the IDX also contracted by 16.64%, declining to Rp 24.97 trillion from Rp 29.95 trillion a week earlier,” Kautsar said in a statement.

Meanwhile, the average daily trading volume dropped 17% to 42.34 billion shares, compared with 51.02 billion shares in the previous week.

Foreign investors remained net sellers in the Indonesian market. On Friday’s market close, foreign investors recorded net sales of Rp 263 billion.

Since the beginning of 2026, foreign investors have posted net outflows totaling Rp 7.29 trillion, reflecting cautious sentiment amid global market uncertainty.
