Breaking: JCI Suddenly Drops Over 1%, Is Profit Taking Underway?
The Jakarta Composite Index (JCI) suddenly reversed course into negative territory after strengthening significantly at the start of the session on Thursday (11/6/2026). As of 10:36 WIB, the JCI fell 1.29% or 76 points to 5,826.02, snapping a rally after two consecutive days of soaring closes.
According to trading data from the Indonesia Stock Exchange (IDX), 212 stocks advanced, 454 declined and 141 remained stagnant. Transaction value reached Rp9.26 trillion with a trading volume of 14 billion shares in 1.13 million transactions.
The JCI’s volatility remains quite high today. The index briefly touched an intraday high of 6,010 (+1.82%) before finally plunging more than 1%.
Market participants continue to monitor global sentiment developments, including international financial market dynamics and foreign capital flow movements. In yesterday’s trading, foreign investors were recorded booking a net sell of Rp3.13 trillion across all markets, even though the JCI managed to close sharply higher.
Indonesia’s financial markets today will still face dynamics ranging from war to investors who continue to scrutinise domestic fiscal resilience and the continuation of global macroeconomics.
The JCI and the rupiah are in a strengthening phase. However, the rally for the JCI and rupiah could be spoiled by two pieces of bad news from the United States, namely a new attack by the US military and soaring US inflation.
The Iran war against the US has heated up again after the United States began launching attacks on Iran on Wednesday, according to a statement from US Central Command (CENTCOM).
In a post on platform X, CENTCOM stated the US military began ‘launching additional self-defence strikes at 5:15 p.m. ET against several targets in Iran at the direction of the Commander-in-Chief.’ The post confirmed that the strikes were conducted ‘in response to Iran’s unprovoked and continued aggression.’
Iranian state media reported that Iran targeted US vessels in the Strait of Hormuz with missile and drone attacks.
This latest attack comes after US President Donald Trump said earlier on Wednesday that the US would hit Iran again ‘very hard’, escalating his public threats while continuing to pressure Tehran to sign a deal.
‘We hit them hard yesterday, and we’re going to hit them hard again today,’ Trump said at the Secure America Act signing event at the White House.
Meanwhile, the US Bureau of Labour Statistics on Wednesday evening released inflation data for the May 2026 period which showed an acceleration in annual inflation to 4.2%. This figure rose from 3.8% in April and marked the highest record since April 2023.
On a monthly basis, headline inflation recorded a 0.5% increase. This surge in headline inflation was specifically dominated by the soaring energy price index, up 3.9% month-on-month or 23.5% year-on-year, due to commodity market pressures.
Conversely, core inflation, which excludes the energy and food sectors, appeared more moderate with a 0.2% monthly increase and 2.9% annually.
Responding to yesterday’s inflation data, market participants are projecting the Fed will hold its benchmark interest rate at the upcoming 17 June meeting, with the potential for a new rate hike now predicted to be pushed back until December.
Amid these tightening dynamics, the new Fed Chair, Kevin Warsh, actually indicated that interest rates have room to move lower in the future. Warsh believes that a surge in productivity from the utilisation of artificial intelligence technology will provide a significant disinflationary impact for the overall economy.
