Significant JCI Strengthening Supported by Easing Market Risks
The Jakarta Composite Index (JCI) continued to strengthen by up to 259 points, or 4.32 percent, to the level of 6,267 during the second trading session on Monday, 15 June 2026, around 14:50 Western Indonesian Time. Research Analyst at Infovesta Kapital Advisori, Arjun Ajnawi, stated that the JCI’s strengthening was triggered by improving investor risk sentiment, following a peace agreement between the United States and Iran. Previously, the JCI closed up 302.08 points, or 5.03 percent, at 6,309 during the first trading session on Monday, 15 June 2026.
"And the reason goes back to that, risk sentiment improved because from the global geopolitical side there was positive news," Arjun said when contacted on Monday, 15 June 2026. He explained that all global stock exchanges experienced significant strengthening, with investors responding positively to the peace agreement between the US and Iran. "From the global side, there was positive sentiment through the announcement of a ceasefire and the opening of the Strait of Hormuz. Asian markets all rallied," he said.
Arjun explained that investors began allocating their funds to risk assets such as the stock market, including in emerging markets like Indonesia. "The reason the market rose is because of this (US-Iran), so clearly investors are entering stocks because stocks are up today," he said.
For context, Pakistan’s Prime Minister, Shehbaz Sharif, said that an agreement between the United States and Iran had been reached, and Pakistan was preparing for the electronic signing of the peace treaty, followed by technical-level talks afterwards. The official signing of the peace agreement is planned to take place on 19 June 2026 in Switzerland. The agreement includes the reopening of the Strait of Hormuz, the lifting of the US naval blockade against Iran, the release of USD 25 billion in frozen Iranian assets, and Iran’s commitment not to develop nuclear weapons during the final negotiation process.
Domestically, investors are awaiting the Global Market Accessibility Review from MSCI and the FTSE index rebalancing on Friday, 19 June 2026, as well as the Bank Indonesia Board of Governors Meeting on Thursday, 18 June 2026, which is expected to raise the BI Rate by 25 basis points to 5.75 percent.
