Aggressive rate hikes and falling reserves drive Bank Indonesia interventions

Bank Indonesia raised its benchmark interest rate by 25 basis points to 5.75% on June 18, a move aimed at attracting capital inflows and stabilizing the rupiah, according to Straitstimes. This latest hike was the second in eight days, part of a series of three rate increases over the past month, including a 50 basis point rise on May 20, as reported by Indonesia Investments. The interventions have occurred alongside a reported $12 billion decline in Indonesia's foreign exchange reserves in the first five months of 2026, reflecting more aggressive market stabilization efforts by the central bank. Broader financial measures have also been intensified to manage ongoing volatility and limit further depreciation.

Sell momentum dominates despite mixed signals from key technicals

Technically, USD/IDR is trading below the MA-20 at Rp17,832 and the MA-50 at Rp17,803 on the hourly chart, but remains above the daily MA-200 at Rp17,030. The Ichimoku Kijun line at Rp17,857 serves as immediate resistance. Momentum indicators provide mixed signals: MACD is neutral and ADX maintains a buy bias, yet RSI stands at 40.9 and, along with the Stoch RSI, is firmly in oversold territory. Commodity Channel Index (CCI) and Bull/Bear Power (BBP) readings also indicate seller-dominated and oversold conditions, while the Awesome Oscillator (AO) highlights continued strong selling momentum. This divergence between trend and oscillators underscores the current sell pressure, with the pair finishing the day near its session lows amid low volatility.

Downside risk prevails as range consolidation likely in short term

Over the next two to three trading days, USD/IDR is likely to consolidate within a volatility band of Rp17,639 to Rp17,851. The probability of a downward move is higher, estimated at 73%, while a reversal to the upside has a 27% chance. A bullish breakout requires a sustained move above the Rp17,857 resistance level, whereas a close beneath Rp17,639 support may trigger a bearish extension. The baseline scenario favors continued range-bound trading until a decisive catalyst emerges.

Anton Kharitonov, expert at Traders Union, sees persistent sell pressure on USD/IDR despite recent central bank action. He notes that Bank Indonesia's rate hikes and intervention signal ongoing challenges for currency stability. Technicals confirm oversold conditions, yet trend indicators stay bearish. "Until the pair breaks decisively above Rp17,857, I remain cautious and expect further downside pressure to persist."

Previously it was reported that USD/IDR maintained a bullish medium-term trend but faced increasing short-term technical caution as momentum signals diverged. The current environment, shaped by Bank Indonesia's accelerated rate hikes and deepening reserve interventions, introduces heightened policy-driven volatility and makes sustained closes above Rp17,857 an important signal for any shift from consolidation toward renewed upside potential.
