Jakarta. Indonesian stocks closed higher on Wednesday, with the Jakarta Composite Index (JCI) rising 35 points, or 0.50%, to 7,092 as easing tensions in the Middle East lifted sentiment across Asian markets.

Pilarmas Investindo Sekuritas said the rally was driven by improving external conditions after the United States signaled that its offensive operations against Iran had ended, reducing concerns over broader geopolitical risks.

US President Donald Trump also said Washington would temporarily halt efforts to assist stranded vessels in the Strait of Hormuz to allow renewed talks with Iran. According to Pilarmas, the market interpreted the move as a sign of potential diplomatic progress and a de-escalation of tensions in the region.

Trump is also expected to discuss the Iran situation with Chinese President Xi Jinping during a summit scheduled for May 14-15, in another effort to reduce wider geopolitical risks.

On the domestic bourse, top gainers included Danasupra Erapacific (DEFI), which surged 34.23%, Ricky Putra Globalindo (RICY), up 34.04%, Pyridam Farma (PYFA), which climbed 25%, and Asuransi Bina Dana Arta (ABDA), which jumped 24.93%.

From China, a private survey pointed to continued economic expansion, with the country’s composite PMI rising to 53.1 in April from 51.5 in March.

“This reflects growth and signals a solid improvement in overall business activity as manufacturing and services output expanded at a faster pace,” Pilarmas said.

Manufacturing output rose to 52.2 from 50.8, while services activity increased to 52.6 from 52.1.

At home, Indonesia’s economy grew 5.61% year-on-year in the first quarter of 2026, exceeding market expectations and reinforcing confidence in the country’s resilience amid global uncertainty.

Bank Indonesia Governor Perry Warjiyo also outlined measures to stabilize the rupiah, with support from President Prabowo Subianto, as the currency remains under pressure against the US dollar.

“The strategies to maintain rupiah stability include market intervention, strengthening liquidity, and tightening foreign exchange purchases. This provides optimism that Bank Indonesia can keep the rupiah stable,” Pilarmas wrote.

Elsewhere in Asia, South Korea’s Kospi soared nearly 7% to a fresh record high on Wednesday as shares of Samsung Electronics jumped 14% on optimism over artificial intelligence growth and hopes for progress in ending the US-Iran conflict.

Shares of SK Hynix also rallied nearly 11%, supported by strong demand expectations for AI-related chips.

Most other Asian markets also advanced, although trading in Tokyo was closed for a holiday. Hong Kong’s Hang Seng rose 1.1% to 26,160, while Shanghai’s Composite Index gained 1.2% to 4,160.

On Wall Street overnight, the S&P 500 climbed 0.8% to 7,259, surpassing its previous all-time high set last week. The Dow Jones Industrial Average added 0.7% to 49,298, while the Nasdaq Composite gained 1% to close at a record 25,326.
