Indonesia Central Bank Surprises with Rate Hike to Stem Rupiah's Fall

Indonesia's central bank surprised markets on Wednesday by raising its benchmark interest rate by 25 basis points to 5.5%, a move aimed at bolstering the rupiah's exchange rate. The Jakarta stock market rebounded sharply on the news, closing over 7% higher. The rate hike came more than a week ahead of the scheduled monetary policy meeting. This follows a surprise 50-basis-point hike just three weeks ago.

The rupiah has fallen more than 7% this year, pressured by surging energy prices linked to the Middle East conflict. According to Bloomberg News, the rupiah has become the worst-performing currency in Asia. Despite facing high energy costs, the Indonesian government, a net oil importer, has insisted on not adjusting heavily subsidized fuel prices.

The rupiah hit an all-time low last week, breaching the 18,000 rupiah per US dollar level. Indonesia's stock market has lost about one-third of its market capitalization this year.

The central bank stated that the rate hike is "to strengthen the stability of the rupiah exchange rate in response to the impact of severe global volatility due to the Middle East war." It described the move as a precautionary measure aimed at keeping inflation within the government's target range of 2.5% plus or minus 1% for 2026 and 2027. The bank also said the hike is expected to "increase yields and attract foreign investment inflows."
