Indonesia's Rupiah Plummets Past 18,000 per Dollar Amid Energy Shock and Policy Turmoil
6/5/2026, 12:24:48 PM
Record Low Exchange Rate
On 4 June 2026 the Indonesian rupiah breached the 18,000-per-dollar psychological barrier, touching 18,001 IDR in one report and 18,028 IDR in another. The slide represented the weakest level since the 1997-1998 crisis and triggered a 4 % plunge in the Jakarta Stock Exchange, erasing roughly one-third of the market’s 2026 gains.
Energy Shock and Trade Balance Deterioration
The depreciation coincided with a sharp rise in global oil prices—crude futures climbed toward $96 per barrel after renewed hostilities in the Israel-Iran theatre. As a net oil importer, Indonesia’s import bill surged, compressing the trade surplus to $89 million in April from $3.3 billion the month before. Permata Bank chief economist Josua Pardede noted that “dollar supply from goods trade is dwindling, while dollar needs for energy imports, raw materials, dividends, foreign debt payments and seasonality needs remain significant.” The combined effect reduced dollar inflows and heightened demand for foreign exchange.
Timeline of Key Developments
- Early April 2026: Rupiah slips past 17,000 IDR, reviving memories of the 1998 crisis.
- Mid-May 2026: Rate reaches ? 17,700 IDR; Bank Indonesia raises the benchmark rate by 50 bps to 5.25 %.

Monetary and Fiscal Policy Responses
Bank Indonesia’s spokesperson Ramdan Denny Prakoso affirmed that the central bank is using “all available policy instruments” to maintain foreign-exchange liquidity, including the rate hike and tighter rules on large USD purchases. Finance Minister Purbaya Yudhi Sadewa framed the parliamentary amendment as a means to “boost economic growth and enhance global competitiveness” while also supporting “job creation.”
Legislative Oversight Expansion and Independence Concerns
The amendment adds economic-growth and employment targets to the central bank’s mandate and subjects its performance to parliamentary review. CSIS analyst Yose Rizal Damuri warned that the move “raises the question of independence,” a view echoed by Central Bank Asia chief economist David Sumual, who cautioned that “if independence is perceived to be weakening, the risk could trigger an increase in risk premiums and put pressure on financial markets.”
Market and Public Reaction
Investors shifted to dollar-denominated and gold hedges, while the broader public expressed anxiety over rising living costs. Pensioner Diana Murdiana observed, “It will create inequality, a visible gap between those earning dollars and those earning rupiah.”

Verbatim Quotes
- “It's not just about exchange rate stability, or just about inflation. It's also about paying attention to economic growth and creating jobs,” — Purbaya Yudhi Sadewa, Finance Minister
- “If independence is perceived to be weakening, the risk could trigger an increase in risk premiums and put pressure on financial markets,” — David Sumual, Central Bank Asia chief economist

Outlook
Analysts suggest that stabilising the rupiah will require coordinated monetary tightening, a revision of the export-proceeds retention rule, and clearer communication on the Danantara sovereign fund. Continued pressure from global oil prices and the evolving parliamentary oversight framework will shape investor confidence and the trajectory of Indonesia’s currency in the coming months.
