Market sentiment today is expected to be mixed after economic data released yesterday showed an improvement in Indonesia’s external resilience. National foreign exchange reserves increased again, providing support for rupiah stability amid global market uncertainty.
Market participants’ attention today will shift to Japan’s economic growth, China’s trade performance, and developments in the US labour market.
This series of data has the potential to influence the movement of the yen, yuan, US dollar, commodity prices, as well as the direction of the rupiah and the Indonesian stock market throughout the day’s trading.
Domestically, the reopening of Soekarno Hatta Airport and the declining activity of Mount Anak Krakatau are positive news.
Indonesia’s foreign exchange reserves rose to US$146.5 billion in August, from US$145.3 billion in July, according to data released yesterday, Monday, 7 September 2026, at 10.00 WIB.
The US$1.2 billion increase brought Indonesia’s foreign exchange reserves to their highest position since March.
The increase was mainly supported by tax and service revenues as well as the government’s withdrawal of foreign loans.
The additional reserves were able to offset the needs of external debt payments and Bank Indonesia’s rupiah stabilisation measures amid global financial market uncertainty.
The reserve position is equivalent to financing around 5.4 months of imports, or 5.3 months of imports and government external debt payments.
