Indonesian authorities are under pressure to provide clearer policy guidance and concrete measures to restore investor confidence after a severe market downturn. The benchmark stock index has plummeted nearly 39%, making it the worst performer among over 90 global indices tracked by Bloomberg. The rupiah has also weakened by 8%, falling to record lows and surpassing the psychological threshold of 18,000 per dollar. Analysts highlight that the upcoming interest rate decision by Bank Indonesia on June 18 and MSCI Inc.'s review of the country's investability are critical for market sentiment. Investors have pulled out a net $422 million from Indonesian bonds and $3.56 billion from local stocks this year, reflecting growing concerns over the government's economic management and President Prabowo Subianto's populist agenda. In response, Bank Indonesia plans to increase interest rates on government deposits to alleviate rising financing costs, but experts caution that without clear fiscal policies, market pressures may persist. The next few weeks are crucial as investors await definitive actions from policymakers.
