Jakarta. Indonesia’s benchmark index, Jakarta Composite Index (JCI) extended its rally on Tuesday, jumping 2.34% or 175 points to close at 7,675, as easing geopolitical tensions and solid domestic data lifted investor sentiment.

The index traded within a range of 7,592 to 7,686 during the session. Trading activity remained robust. Data from RTI Business showed volume reaching 53.29 billion shares, with turnover of Rp 24.8 trillion ($1.44 billion) across more than 3.1 million transactions. Market breadth was firmly positive, with 548 gainers against 151 decliners and 119 unchanged stocks.

Top gainers were led by Ricky Putra Globalindo (RICY), which surged 34.88%, followed by Puri Global Sukses (PURI) rising 34.75%, PP Presisi (PPRE) advancing 34.65%, and Danasupra Erapacific (DEFI) climbing 34%.

On the losing side, MNC Studios International (MSIN) dropped 14.77%, Guna Timur Raya (TRUK) fell 14.69%, Dafam Property Indonesia (DFAM) declined 13.85%, and Capitol Nusantara Indonesia (CANI) slipped 9.93%.

Pilarmas Investindo Sekuritas said the JCI’s rally tracked gains across Asian markets, driven by renewed optimism over developments in US–Iran relations.

US President Donald Trump signaled that Iran had attempted to reopen negotiations, while Iranian President Masoud Pezeshkian indicated readiness to resume talks as long as they adhere to international law.

The statements followed earlier failed negotiations that had escalated tensions, including a US blockade of the Strait of Hormuz, a critical global oil shipping route.

“However, the emergence of renewed dialogue hopes has improved market optimism. Expectations of a deal have eased concerns over a spike in oil prices, potentially lowering global inflationary pressure,” Pilarmas wrote in its research note on Tuesday. “This condition also reduces speculation over aggressive monetary policy by major central banks,” the brokerage added.

Domestically, sentiment was further supported by stronger economic data. Bank Indonesia reported retail sales grew 6.5% year-on-year in February 2026, accelerating from 5.7% in January.

“This reflects resilient consumer purchasing power and sustained economic activity amid global uncertainty,” Pilarmas said.

Across the region, Asian equities advanced in line with Wall Street gains, while oil prices declined as expectations grew for a second round of US–Iran talks aimed at ending the ongoing conflict.

Japan’s Nikkei 225 rose 2.4% to 57,877, while South Korea’s Kospi jumped 2.7% to 5,967 after briefly surpassing the 6,000 level intraday.

Hong Kong’s Hang Seng gained 0.7% to 25,832.85, and China’s Shanghai Composite climbed 1% to 4,026.63. China reported export growth of 2.5% in March, missing expectations, although analysts noted that shipments tied to AI and renewable energy could continue supporting overall exports this year.

Investors remain hopeful for a sustained de-escalation in the Iran conflict, now entering its seventh week, as Washington and Tehran consider a second round of talks ahead of a temporary ceasefire deadline next week.

“I can tell you that we’ve been called by the other side,” Trump said, without elaborating.

On Wall Street, US stocks closed higher overnight. The S&P 500 rose 1% to 6,886, the Dow Jones Industrial Average gained 0.6% to 48,218, and the Nasdaq Composite advanced 1.2% to 23,183.
