JCI Opens Weaker, Down 0.13% to 6,532

The Indonesia Composite Index (JCI) opened weaker in trading on Monday (14/09/2026). At 09:00 WIB, the JCI was recorded down 0.13%, or 8.77 points, to the level of 6,532.61.

According to data from the Indonesia Stock Exchange, the JCI opened at 6,533.87, lower than the previous closing position of 6,541.38. A total of 249 stocks rose, 143 declined, and 571 remained unchanged. Transaction value at the start of trading reached Rp 248.4 billion, involving 361.7 million shares across 44,110 transactions.

The movement of the JCI on Monday’s trading session is potentially influenced by increasing geopolitical tensions in the Middle East, rising global oil prices, and expectations of an interest rate hike by the US central bank. These sentiments have developed since the Indonesian financial market closed last Friday, meaning domestic investors are likely to respond to the latest developments in today’s trading.

Tensions in the Middle East have escalated following Houthi attacks against Saudi Arabia and disruptions to shipping lanes in the Gulf region, threatening the global energy supply. Damage to Saudi Arabian oil pipelines, which serve as an alternative route for oil shipments bypassing the Strait of Hormuz, has further heightened market concerns. If supply disruptions continue, up to 4% of the world’s oil supply could be affected, in addition to supplies already disrupted by shipping issues in the Strait of Hormuz.

These conditions have the potential to drive up oil prices, which breached US$100 per barrel last week. A surge in energy prices could increase global inflationary pressures and affect expectations for central bank monetary policies.

From the US, August consumer inflation data showed that price pressures remain high. The Consumer Price Index (CPI) rose 0.4% month-on-month, higher than the 0.1% increase in July. Meanwhile, core inflation increased 0.3% month-on-month, exceeding market estimates of 0.2%.

These developments have strengthened expectations for a 25 basis point interest rate hike by the Federal Reserve during its meeting on 15-16 September 2026. According to CME FedWatch, the probability of a rate hike to the 3.75%-4.00% range has reached 87.3%.

A US interest rate hike could potentially drive a stronger US dollar and higher US government bond yields, thereby putting pressure on the Rupiah and risky assets in emerging markets, including Indonesian stocks.

On the other hand, the strengthening of Wall Street during Friday night’s trading could serve as a positive sentiment for the domestic stock market. However, investors will continue to closely monitor oil price developments and the direction of the Fed’s policy.

In addition to global sentiment, market participants are also awaiting several important economic data points throughout this week, including China’s retail sales, Indonesia’s external debt, as well as the interest rate decisions from the Fed and the Bank of Japan (BOJ).
