JAKARTA — Bank Indonesia (BI) is set to hold its Board of Governors Meeting (RDG) on May 19–20, 2026, amid intensifying market pressure. Economists are projecting that the persistent weakening of the rupiah may force the central bank to tighten its benchmark interest rate, or BI Rate, to stabilize the economy.
With the current benchmark rate sitting at 4.75%, analysts suggest the room for central bank intervention is rapidly narrowing. Many market experts now anticipate a potential rate hike ranging from 25 to 50 basis points (bps) during this month’s meeting.
Josua Pardede, Chief Economist at PT Bank Permata Tbk. (BNLI), advocates for a 25 bps hike to 5.00%. While he acknowledges that the central bank technically has the capacity to keep rates steady, he argues that the current market volatility makes a rate increase essential to restore confidence in the national currency.
Market Turbulence and External Pressures
The urgency stems from the sharp depreciation of the rupiah, which hit Rp17,666 per US dollar on May 18, 2026. Simultaneously, yields on 10-year Indonesian Government Bonds (SBN) have climbed to between 6.82% and 6.86%. “This indicates that the pressure is not confined to the currency market; it is spilling over into the bond and stock markets,” Josua explained. “If BI maintains the current rate without signaling a stronger policy stance, the market may perceive the bank as falling behind, which risks further depreciation.”
External factors further complicate the landscape. A strengthening US dollar—driven by rising global oil prices and high US Treasury yields—has increased the risks of imported inflation and a widening fiscal deficit due to energy subsidies. Josua clarified that a rate hike at this juncture is not intended to curb economic growth, which remains solid, but rather as a necessary stabilization cost to prevent higher future expenses, such as soaring import costs and squeezed business margins.
Diverse Perspectives on Monetary Policy
Teuku Riefky, a macroeconomics and financial market economist at LPEM FEB UI, echoes the call for a 25 bps increase. He notes that while annual inflation for April 2026 cooled to 2.42% thanks to the government’s decision to cap subsidized fuel prices, the external pressure on the rupiah is overwhelming. BI has reportedly utilized over US$10 billion in foreign exchange reserves over the past four months to stabilize the exchange rate, a trend that warrants a policy rate adjustment.
A more aggressive approach comes from Fakhrul Fulvian, Chief Economist at Trimegah Sekuritas Indonesia, who suggests a 50 bps hike. He views this as a vital “pre-emptive” and “front-loading” strategy to protect the credibility of macroeconomic policy. “In a situation like this, the central bank is not just managing inflation; it is defending the very anchor of its policy,” Fulvian remarked, drawing parallels to 2018 when aggressive hikes were necessary to maintain market trust. He estimates that such a move could help the rupiah recover to the Rp16,800 range.
Conversely, some remain cautious. David Sumual, Chief Economist at PT Bank Central Asia Tbk. (BBCA), suggests that the central bank may hold the rate steady at 4.75%. He points to the relatively stable inflation rate as the primary justification for maintaining the status quo, provided there are no major adjustments to subsidized fuel prices.
As the Board of Governors prepares for their deliberations, the central bank faces a delicate balancing act: managing inflation, defending the rupiah, and maintaining economic stability in an increasingly volatile global climate.
Summary
Bank Indonesia is expected to consider a benchmark interest rate hike of 25 to 50 basis points during its May 2026 Board of Governors Meeting to address significant currency depreciation and market volatility. The rupiah’s decline to Rp17,666 per US dollar, combined with rising bond yields and external pressures like a strong dollar, has prompted many economists to advocate for tightening. Proponents argue that an increase is essential to stabilize the economy, restore market confidence, and mitigate risks such as imported inflation.
While some experts support a proactive hike to protect monetary policy credibility, others maintain a more cautious outlook, citing stable domestic inflation figures as a reason to hold rates steady. Bank Indonesia must balance these competing perspectives as it weighs the necessity of intervention against the potential impact on growth. Ultimately, the decision will reflect the central bank’s efforts to anchor the economy amidst ongoing global financial pressures and declining foreign exchange reserves.
