Rupiah breaches 18,015 per dollar as IHSG falls 3.04%
The weak currency is expected to strain import-dependent industries, from pharmaceuticals to automotive, by raising input costs.
The rupiah weakened again to breach 18,015 per U.S. dollar in trading on Thursday, June 4, 2026, while the IHSG fell about 3.04 percent. Said Abdullah, chairman of the DPR budget committee, said the level above 17,600 has already crossed a psychological threshold and reflects a problem that is no longer tied solely to economic fundamentals. He pointed to investor doubts about legal certainty, policy consistency and government governance. According to Said, Bank Indonesia intervention through a triple intervention scheme in the spot, NDF and DNDF markets would not be enough without policy coordination to restore market confidence. Anwar Abbas said the rupiah's weakness was also driven by foreign investors pulling funds out, which then lifted demand for dollars. He warned that the pharmaceutical, electronics, textile and garment, downstream plastics and petrochemicals, and automotive industries are most exposed because they rely heavily on imported raw materials.
