Jakarta Stock Index Plummets Over 2% Amid Geopolitical Tensions and Energy Profit‑Taking Rally

Markets Wobble as Geopolitics Weigh on Investor Sentiment

Breaking from jakarta, the Indonesia Stock Exchange’s IHSG slid by more than 2% in late trading before trimming losses. By 14:33 local time,the index had fallen about 2.17% to 8,742.51, only to retreat to a negative but smaller decline moments later.

Analysts linked the move to escalating global tensions and a rotation out of riskier holdings. Traders cited a fresh wave of geopolitical concerns and profit-taking in energy shares as central factors behind the session’s volatility.

What triggered the sell-off

Market watchers point to two main forces: geopolitical risk and sector rotation. Protests in Iran and the potential for international involvement created a risk-off mood among investors, while some participants booked profits after a rally in energy stocks, pulling the broader market lower.

Another thread in the conversation centered on U.S. policy independence, following reports about an inquiry involving a senior Federal Reserve official. While authorities insist that monetary decisions remain anchored on inflation and employment goals, market participants remain sensitive to any sign that policy independence could be affected.

Safe-haven demand and price signals

Gold and silver rose as investors sought shelter amid heightened uncertainty, underscoring their traditional role as crisis hedges. Historically, gold can move inversely to stocks, though correlations can shift with the broader macro backdrop.

Short trading week amplifies caution

The local market week is unusually short due to isra Mi’raj, with sessions limited to four days. Reduced liquidity can magnify swings and heighten sensitivity to headlines and data releases.

What’s next for traders

Market participants are eyeing upcoming U.S. inflation data and broader commodity price movements. analysts say the next set of inflation figures and central-bank signals will shape risk appetite in the near term.
