Indonesia's Central Bank Hikes Rates to Stabilise Plunging Rupiah
6/9/2026, 11:28:02 AM
Rate Hike Details
On 9 June 2026, Bank Indonesia (BI) raised its benchmark BI-Rate by 25 basis points to 5.50 percent in an off-cycle meeting. The overnight deposit rate moved to 4.50 percent and the lending rate to 6.25 percent, after a 50-basis-point increase in May.
Currency Context
The rupiah fell about 8 percent this year and 7 percent since the Iran-related war, hitting a record low of 18,190 per dollar before edging to 18,075 after the hike. Foreign-exchange reserves dropped $12 billion in 2026, with a $1.3 billion decline in May, leaving $144.9 billion.
Key Actors
Governor Perry Warjiyo said the bank acted to make BI-issued securities more attractive despite preferring not to raise rates. BCA chief economist David Sumual noted the 12-month SRBI yield of 7.25 percent may demand a more aggressive stance. Barclays projects a further 25-bp rise to 5.75 percent at the 17-18 June meeting, with a possible 50-bp jump if pressure persists.
Data Snapshot
- Benchmark rate: 5.50 % (up 25 bps)
- Rupiah: 18,190 IDR/USD low; 18,075 IDR/USD after hike
- Reserves: $144.9 bn (down $1.3 bn in May)
- SRBI 12-month yield: 7.25 %
Official Statements Summary
BI described the hike as a further step to stabilise the rupiah amid heightened global volatility from the Middle East conflict and to keep inflation within the 2026-2027 target range. The policy also aims to attract foreign portfolio inflows and preserve external economic resilience.
Criticism and Market Concerns
Analysts attribute the rupiah’s slide to President Prabowo Subianto’s expansive fiscal plans, a ballooning fuel-subsidy budget, and doubts about BI’s autonomy under new commodity-export rules. The swift reserve drawdown and reliance on aggressive rate moves raise questions about the sustainability of monetary tightening.
