On March 12, 2026), Indonesia’s financial markets saw the rupiah weaken slightly to Rp16,899/USD, the Jakarta Composite Index (IHSG) close lower at 7,389, and oil-driven volatility continue to pressure sentiment. Regulatory developments and fiscal measures also shaped investor outlook.
1. Rupiah Weakens to Rp16,899/USD
- The rupiah closed at Rp16,899 per USD, down from Rp16,867 the previous day, reflecting a 0.19% depreciation. The weakness was linked to surging global oil prices, which briefly surpassed USD 100 per barrel, and geopolitical tensions in the Middle East.
- Analysts noted that disruptions in the Strait of Hormuz and Iraq heightened supply concerns, driving safe-haven demand for the U.S. dollar. Bank Indonesia is expected to continue interventions to prevent the currency from breaching the Rp17,000/USD threshold.
2. IHSG Closes Lower at 7,389.4 (-0.69%)
- The Jakarta Composite Index (IHSG) ended at 7,389.4, down 0.69%, reversing earlier gains in the first trading session. Foreign investors recorded a net sell of Rp730 billion, adding pressure to the index.
- Sectoral performance was mixed, with energy and transport offering support, while cyclicals and technology weighed on the index. Analysts highlighted that volatility remains elevated due to global risk-off sentiment and oil market uncertainty.
3. Oil Price Surge Adds Inflation Risks
- Global oil prices rose nearly 5% overnight, driven by reports of tanker strikes and supply disruptions in the Middle East. This renewed inflationary concerns for Indonesia, a net oil importer.
- Higher oil prices are expected to pressure household consumption and fiscal balances, even as commodity-linked sectors like palm oil and energy stocks benefit. The government’s recent IDR 11.16 trillion Eid allowance distribution aims to cushion domestic demand.
