Bank Indonesia raises rates to 5.75% in third hike in a month to defend the rupiah

Indonesia's central bank has raised its benchmark interest rate again, lifting the BI-Rate by 25 basis points to 5.75% at its June meeting in a bid to shore up the rupiah against the pressures unleashed by the Middle East conflict. The move marks the third increase in roughly a month, a striking burst of tightening from a central bank that had spent the prior period cutting rates.

The decision, announced after the Board of Governors meeting on June 17-18, followed an unscheduled 25-basis-point hike on June 9 and a larger 50-basis-point increase in late May, bringing the cumulative tightening to 75 basis points and pushing the policy rate up from 4.75%. Bank Indonesia also raised its deposit facility and lending facility rates by the same increment, to 4.75% and 6.50% respectively. These represent the first tightening moves by the central bank since 2024, reversing a cycle of cuts that had taken rates to multi-year lows.

The driving force behind the rapid policy shift is the rupiah, which has come under sustained pressure as geopolitical tensions in the Middle East triggered capital outflows from emerging markets. As global investors retreated from riskier assets and the US dollar strengthened, the Indonesian currency slid toward historically weak levels, prompting the central bank to prioritize stability. Governor Perry Warjiyo framed the decisions as preemptive measures aimed at strengthening the rupiah and keeping inflation within the government's target range of 2.5%, plus or minus one percentage point, for 2026 and 2027.

Warjiyo has been candid about the trade-offs. Having earlier indicated that the central bank was reluctant to raise rates, he explained that the decision was taken in part to attract foreign portfolio investment inflows into the country, leaning on higher yields to compete for capital in a volatile environment. Higher interest rates create a stronger pull toward Indonesian fixed-income assets, and the central bank's various policy responses had already drawn renewed portfolio inflows into rupiah securities and government bonds earlier in the quarter.

Indonesia's external buffers remain solid, which gives the central bank room to maneuver. Reserve assets stood well above the levels considered adequate by international standards, covering several months of imports, and the central bank has pointed to a manageable current-account position. Those cushions help explain why policymakers have opted for measured rate increases rather than more dramatic interventions, even as the rupiah has tested uncomfortable lows.

The episode illustrates the broader squeeze facing emerging-market central banks in the current environment. With the US Federal Reserve having turned more hawkish and the dollar climbing, authorities across the developing world are being forced to defend their currencies and guard against imported inflation, often by tightening policy even when domestic conditions might argue for easier settings. Indonesia's pivot from cutting to hiking in the space of weeks captures that tension vividly.

Looking ahead, the central bank's path will hinge on how the rupiah behaves and whether the easing of the energy shock, following the US-Iran peace agreement and the slide in oil prices, takes some pressure off inflation and the currency. For now, Bank Indonesia has signaled that defending stability takes precedence, and that it is prepared to keep acting if global conditions demand it.
