JCI Opens Lower as Asian and Wall Street Markets Tumble Amid Middle East Conflict Escalation
Jakarta – The Jakarta Composite Index (JCI) opened down 3 points, or 0.05 percent, at 5,899 at the start of trading on Thursday, 11 June 2026.
Head of Retail Research at BNI Sekuritas, Fanny Suherman, predicted the JCI would test the psychological level of 6,000 during today’s trading. “The JCI today has the potential to test the psychological level at 6,000,” Fanny stated in her daily research note.
She noted that the majority of Asian stock markets declined in Wednesday’s trading, as geopolitical tensions in the Middle East intensified after the United States launched fresh strikes against Iran. At the same time, global oil prices strengthened again, sparking market concerns over global inflationary pressures and the prospect of higher interest rates for a longer period.
Japan’s Nikkei index weakened by 1.9 percent, and the Topix fell 1.2 percent. In South Korea, the Kospi index plunged 4.5 percent, and the Kosdaq dropped 1.7 percent. Meanwhile, Hong Kong’s Hang Seng weakened by 0.6 percent, Taiwan’s Taiex fell 3.3 percent, while Australia’s ASX 200 rose 0.6 percent.
On another front, markets were awaiting the release of US inflation data scheduled for Wednesday local time. Based on expectations, annual US inflation for May was forecast to rise to 4.2 percent.
“JCI support is at the 5,750–5,840 level, while JCI resistance lies in the 6,000–6,050 range,” she added.
For context, Wall Street stock indices slumped in trading on Wednesday. The Dow Jones Industrial Average fell more than 900 points after US President Donald Trump threatened to launch further attacks on Iran. The threat raised investor concerns over escalating conflict in the Middle East.
The Dow Jones closed down 1.87 percent, the S&P 500 fell 1.62 percent, and the Nasdaq Composite dropped 1.98 percent. Pressure mounted after Trump stated that the negotiation process with Iran had taken too long. He asserted that the US would strike Iran very hard if no agreement was reached.
“Iran has been negotiating for far too long on a deal that would actually benefit them greatly. Now they must pay the price,” Trump wrote via social media.
