Indonesia’s financial market continues to face dynamics ranging from war to investors closely monitoring domestic fiscal resilience and ongoing geopolitical and global economic sentiment. The JCI and rupiah had appeared to weaken following US inflation data that climbed again, increasing the potential for a rate hike by the Fed, which tends to cripple risky assets such as equities, especially in developing countries like Indonesia.

President Donald Trump said the US and Iran could potentially sign a peace agreement this weekend that would reopen the Strait of Hormuz for shipping. However, Iran stressed it has not yet made a final decision, although most of the deal’s contents have been settled. Trump claimed the agreement would end the three-month war and ensure Iran does not possess nuclear weapons. He also mentioned the Strait of Hormuz would be reopened immediately after the agreement is signed. Trump’s statement came after he cancelled plans for a military strike against Iran due to progress in negotiations. The news boosted US stocks and pushed oil prices lower.

Meanwhile, the European Central Bank yesterday officially decided to raise its benchmark interest rate by 25 basis points to 2.4%. This tightening step marks the first increase since 2023, driven by policymakers’ commitment to anchor inflation back to the medium-term target of 2%. The decision directly responds to surging energy costs and persistent inflation risks due to the escalation of war in the Middle East 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 the previous 2.6%, and for 2027 to 2.3%.
