The 2025 economic outlook for Indonesia is not optimistic. The OECD expects Indonesia's economy to grow by only 4.9%, far below the government's vision of 6-8%. The International Monetary Fund (IMF) October report projected growth of 4.9%, an upward revision of 0.1%. Indonesia's central bank forecasts growth between 4.6% and 5.4%, while the government targets 5.2%, higher than the World Bank's (WB) 4.8%. On a quarterly basis, Indonesia's economy grew 4.87% in Q1, rose to 5.12% in Q2, then slowed to 5.04% in Q3, below the economists' expectation of 5.0%, due to investment growth falling from 6.99% in Q2 to 5.04% in Q3, and the investment-to-GDP ratio was only 31.48%, with an Incremental Capital-Output Ratio (ICOR) of 6.245. Compared to other countries, Indonesia has a relatively high ICOR, indicating low economic efficiency. For example, the ICORs of Vietnam, Thailand, Malaysia, and India are 4.6%, 4.4%, 4.5%, and 4.5%, respectively. India's investment-to-GDP ratio is similar to Indonesia's, but its economic growth is higher. India plans to reduce its ICOR to 2.7 by 2030, while Indonesia would need an investment-to-GDP ratio of 49.96% to achieve 8% growth. To reach the 6-8% growth target, the government needs to improve economic efficiency and lower the ICOR to 5-6; promote technological innovation and increase digital transformation coverage; improve the ease of doing business and carry out institutional reforms; adopt the latest digital technologies; and identify leading manufacturing enterprises to concentrate resources on enhancing their efficiency.
