Inflation and caution ahead
Indonesia’s inflation rose to 3.2 percent year-on-year in August 2026 from 2.9 percent in July, driven mainly by food and gold prices. Month-on-month inflation reached 0.2 percent. Core inflation rose to 1.93 percent year-on-year. Manufacturing PMI fell to 49.8 in August, entering contraction.
Rully Arya Wisnubroto, Head of Research and Chief Economist at Mirae Asset Sekuritas Indonesia, said the domestic backdrop remained constructive, although food inflation increases and global yield pressure still limited room for more aggressive risk-on. Jessica Tasijawa, Fixed Income Analyst at Mirae Asset Sekuritas, said elevated inflation could keep Bank Indonesia cautious in maintaining inflation and rupiah stability.
