Rupiah Weakens as Market Awaits Definitive BI Governor Appointment

The Indonesian rupiah closed Tuesday, July 28, 2026, at Rp 18,083 against the US dollar, marking a 0.41% or 74-point decline from the previous day's close. The Jakarta Interbank Spot Dollar Rate (JISDOR) also reflected this weakening, moving to Rp 18,088 from Rp 17,995.

Market analyst Ibrahim Assuaibi cited both domestic and global factors for the rupiah's fall. Domestically, the market faces economic uncertainty after the unexpected resignation of Bank Indonesia Governor Perry Warjiyo. This departure was met with negative market sentiment, as it could increase short-term uncertainty during the leadership transition, especially amid rupiah depreciation, foreign capital outflow, and potential global interest rate hikes.

However, the appointment of Destry Damayanti as a potential successor brought some optimism, signaling the central bank's commitment to maintaining rupiah stability, controlling inflation, and ensuring financial system stability. The market now awaits the definitive appointment of the new BI Governor, hoping it proceeds smoothly and upholds the central bank's credibility and independence.

S&P Global Ratings noted Perry Warjiyo's resignation would not directly impact Indonesia's sovereign rating, though it could slightly increase risks related to the country's policy outlook, according to Ibrahim. Meanwhile, global attention is on the US Federal Reserve, which is widely expected to maintain its interest rates on Wednesday, July 29, 2026. The CME FedWatch tool indicates a 62% probability of this outcome. Market sentiment remains volatile due to the dynamic situation in the Middle East, which has seen oil prices surge.
