Market Rallied Immediately from Opening Bell

According to RTI Business data at 09:05 WIB, the index opened at 6,118 and immediately strengthened from the start of the trading session. IHSG reached an intraday high of 6,194 with a low of 6,118. A total of 519 stocks advanced, 84 declined, and 104 remained unchanged, reflecting overwhelmingly bullish market sentiment across the board.

Trading volume reached 3.53 billion shares with a transaction value of IDR 2.20 trillion from 208,548 trades. Market capitalization surged to IDR 10,852.80 trillion alongside the index rally. This figure represents a broad-based restoration of investor confidence in Indonesia's capital market following a period of global geopolitical uncertainty that had weighed on emerging market assets.

Foreign Investors Record Net Buy of IDR 287 Billion

Foreign investors recorded a net foreign buy of IDR 287.77 billion across all markets, signaling the return of capital inflows after a period of cautious positioning. In the regular market, net foreign buy reached IDR 287.36 billion, while in the negotiation and cash markets, net buy was recorded at IDR 417.12 million. These capital inflows serve as a strong indicator that global investors are once again turning their attention to risk assets in emerging markets.

Domestic investors, however, continued to dominate trading activity. Of the total trading volume of 37.5 billion shares, domestic investor transactions reached 78.67 percent or approximately 30.2 billion shares, while foreign investors contributed 21.33 percent or around 8 billion shares. This domestic dominance provides additional market stability, as local investors generally maintain a longer-term perspective on the Indonesian market and are less prone to sudden capital flight.

Big Cap Stocks Led the Rally

The IHSG surge was fueled by significant gains in several large-cap stocks. PT Bank Central Asia Tbk (BBCA) rose 4.64 percent to 6,200, PT Bank Rakyat Indonesia Tbk (BBRI) gained 2.81 percent to 2,930, and PT Bank Mandiri Tbk (BMRI) climbed 3.81 percent to 4,360. The banking sector, which carries the heaviest weighting in the IHSG, emerged as the primary driver of this morning's rally.

In other sectors, PT Chandra Asri Pacific Tbk (TPIA) surged 6.49 percent to 1,970, PT Aneka Tambang Tbk (ANTM) gained 4.91 percent to 2,990, PT Bumi Resources Tbk (BUMI) rose 7.01 percent to 168, and PT Petrindo Jaya Kreasi Tbk (CUAN) added 5.56 percent to 760. The broad-based nature of gains across diverse sectors confirms that this rally is not confined to a single industry but reflects widespread optimism about the economic outlook.

Global Sentiment: US-Iran Peace Deal as Primary Catalyst

The IHSG rally cannot be separated from improving global sentiment following Pakistan's announcement of a peace agreement between the United States and Iran. The reopening of the Strait of Hormuz, through which approximately 20 percent of the world's oil and LNG passes, provides much-needed certainty regarding energy prices and global supply chains. The psychological impact of the conflict's resolution was immediately reflected in Asian equity markets, including Indonesia.

The decline in crude oil prices that accompanied the peace announcement also serves as a supportive factor for oil-importing countries like Indonesia. Lower energy costs have the potential to ease inflationary pressures, creating room for Bank Indonesia to maintain accommodative monetary policies. The combination of improving global sentiment and solid domestic fundamentals creates an ideal environment for IHSG to sustain its upward trajectory in the near term, provided global conditions remain stable.
