JCI Surges 2.68% in First Session to 6,043

The Jakarta Composite Index (JCI) surged 2.68% to 6,043.55 at the end of the first trading session on Friday (12/6/2026). A total of 610 stocks rose, 101 fell, and 100 remained unchanged. Transaction frequency reached 1.36 million times, with trading volume hitting 21.56 billion shares worth Rp 11.85 trillion. The JCI opened stronger, returning to positive territory after a correction in the previous session. Nearly all sectors advanced, with only the healthcare sector declining. The highest gains were recorded in the raw materials, energy, infrastructure, and industrial sectors. Blue-chip and conglomerate stocks surged in unison, with BBCA, BRMS, AMMN, TLKM, and BUMI serving as the main drivers of the JCI’s performance. Financial markets continue to face dynamics ranging from war to investors scrutinising domestic fiscal resilience and ongoing geopolitical and global economic sentiment. The JCI and rupiah had previously weakened following the release of US inflation data, which rose again, increasing the potential for a Federal Reserve interest rate hike that tends to cripple risky assets like stocks, especially in developing countries such as Indonesia. President Donald Trump stated that the US and Iran could sign a peace agreement this weekend, which would reopen the Strait of Hormuz for shipping. However, Iran emphasised that a final decision has not been made, although most of the agreement’s contents have been settled. Trump claimed the deal would end the three-month war and ensure Iran does not possess nuclear weapons. He also mentioned the Strait of Hormuz would reopen immediately after the agreement is signed. Trump’s statement came after he cancelled plans for a military strike on Iran due to progress in negotiations. The news boosted US stocks and lowered oil prices. Meanwhile, the European Central Bank officially decided yesterday to raise its benchmark interest rate by 25 basis points to 2.4%. This tightening move marks the first increase since 2023, driven by policymakers’ commitment to anchoring inflation back to the medium-term target of 2%. The decision directly responds to surging energy costs and persistent inflation risks stemming from the Middle East escalation and disruptions to oil shipping routes through the Strait of Hormuz. Following the policy move, the ECB revised its headline inflation projection for 2026 upwards to 3.0% from 2.6%, and the 2027 forecast to 2.3%.
