Strengthening the 'policy anchor' for Rupiah stability

Jakarta — Exchange rate fluctuations are not merely numbers moving up and down on the trading screens of financial markets. For a developing country like Indonesia, exchange-rate movements are the economic heartbeat that determines food prices in markets, production costs in factories, and the calculations of the state budget. When the storm of global uncertainty returns to blow, pressing the currencies of many developing countries including the rupiah, swift and tactical policy responses become essential. It is this dynamic that underpinned Bank Indonesia’s bold step in the May 2026 Board of Governors Meeting (RDG). The central bank’s surprising yet measured move was to raise the BI-Rate by 50 basis points, lifting the policy rate from 4.75 percent to 5.25 percent. This decision was followed by adjustments to other monetary instruments, with the deposit facility rate now at 4.25 percent and the lending facility reaching 6 percent. The policy also ends the long-running trend of keeping the policy rate unchanged since the end of last year. Looking back over 2025, BI was indeed aggressive in monetary easing, cutting the policy rate five times with a total reduction of 125 basis points to stimulate domestic growth. Throughout last year, BI also actively cut the policy rate to spur the domestic economy, but when external turmoil such as high US interest-rate policy and rising geopolitical tensions began to threaten the rupiah’s strength, the central bank did not hesitate to pivot (a u-turn). By tactically raising the BI-Rate by 50 basis points, BI immediately mounted a ‘defensive shield’ for monetary policy to withstand capital outflows, dampen exchange-rate volatility, and ensure the national economic foundation remains robust against the onslaught of global uncertainty.
