Bank Indonesia kept its benchmark interest rate unchanged at 4.75% on March 17, marking the sixth consecutive hold and a formal pivot in the central bank’s policy stance, as the US-Israel-Iran conflict drives capital outflows and rupiah depreciation toward levels not seen since the Asian Financial Crisis. Governor Perry Warjiyo announced that monetary policy will now be directed “mainly toward stability,” explicitly dropping the language the central bank had previously used to signal openness to further rate reductions.
The decision, reached at the Board of Governors meeting on March 16–17, 2026, was anticipated unanimously. All 26 economists in a Reuters pre-decision poll forecast a hold. The policy outcome, however, carries significance beyond the rate itself: it marks the effective end of an easing cycle that delivered 125 basis points in cumulative cuts throughout 2025.

The Iran War Factor
Bank Indonesia’s official statement published on March 17 cited the deteriorating global outlook stemming from the Middle East conflict as the primary driver of the rate decision (bi.go.id). Governor Warjiyo said conditions had worsened since late February 2026, when the US-Israel-Iran war escalated, weakening non-US dollar currencies broadly and placing the rupiah under sustained pressure. The central bank indicated it will continue to strengthen external resilience through “various monetary policy instruments,” including intervention in spot and non-deliverable forward foreign exchange markets as well as onshore DNDF transactions.
The rupiah’s proximity to its all-time crisis-era low is a key reference point for market participants. The currency’s record low of Rp16,800 per dollar was recorded in June 1998 during the Asian Financial Crisis, a period that brought Indonesia to the brink of sovereign default. The rupiah was trading just below Rp17,000 on Tuesday afternoon following BI’s announcement, having shown no marked reaction to the widely anticipated decision.
A Shift In Forward Guidance
The most consequential aspect of the March 17 announcement was Governor Warjiyo’s explicit removal of language signaling room for further rate cuts. “We are no longer conveying the possibility of an interest rate cut,” Warjiyo told a press conference, adding that policy would be “directed mainly toward stability” as the Iran war had weakened the rupiah and triggered capital outflows from emerging markets. This marks a meaningful departure from Bank Indonesia’s posture through most of 2025, when the central bank consistently flagged openness to easing in line with the inflation target corridor.
Economists polled by Reuters before the decision had already adjusted their expectations. The Economist Intelligence Unit’s Tay Qi Hang said the central bank “can’t resume its accommodative stance given how much the rupiah has weakened” and placed the earliest plausible timing for a rate cut at June 2026, contingent on conditions stabilizing. More than half of the 19 economists in the poll expected the policy rate to end 2026 at 4.25%, though no consensus existed on timing.
Capital Outflows And Governance Concerns
The rate decision arrives against a compounding set of pressures on Indonesian financial markets. Bank Indonesia’s own disclosure at the press conference revealed that portfolio investment recorded a net outflow of USD 1.1 billion in the first two weeks of March alone. The Economist Intelligence Unit attributed part of this investor caution to concerns over fiscal credibility linked to the spending commitments of President Prabowo Subianto, as well as questions regarding central bank independence following the appointment of the president’s nephew as a deputy governor.
These concerns have compounded sovereign rating pressures from two major agencies. Moody’s Ratings revised Indonesia’s sovereign credit outlook to negative on February 5, 2026, affirming the Baa2 investment-grade rating while citing reduced predictability and coherence in policymaking and weakening governance. Fitch Ratings issued a matching revision on March 4, 2026, affirming the BBB rating while flagging rising policy uncertainty and increasingly centralized decision-making. ANZ Research noted ahead of the meeting that the dual sovereign downgrades had “removed the scope for an easing bias” and would keep the central bank’s focus firmly on foreign exchange stability and inflation risk management.
Macroeconomic Backdrop
Indonesia’s economic growth outlook remains within a positive range. Bank Indonesia projects GDP growth of 4.9–5.7% in 2026, with acceleration expected in 2027. Inflation remains within the target band, though upward pressure from rising global energy prices tied to the Iran conflict introduces risk to the import-inflation channel. The University of Indonesia’s Institute for Economic and Social Research had recommended the hold ahead of the decision, citing specifically the rising import inflation risk from higher global crude prices.
Foreign exchange reserves remain above the international adequacy threshold of three months of imports. As of end-January 2026, reserves stood at USD 154.6 billion, equivalent to approximately 6.3 months of imports. By the time of the rate decision, reserves had declined to USD 151.9 billion, reflecting drawdowns linked to tax and debt servicing obligations.
