Malaysia will release August inflation data on 17 September at 20:00 ET, with the year-over-year rate expected to hold at 1.8%. Indonesia’s Bank Indonesia rate decision is scheduled for 23 September. Thailand’s stronger export and investment momentum supports the revised 2.5% 2026 growth forecast.

Thailand’s private equity trust will channel 1 billion baht into new-economy firms, complementing the submarine-cable study.

Other Economic Notes

Indonesia’s appointment of Suahasil Nazara as finance minister is viewed as a move that could ease investor concerns over fiscal credibility. Wildfires continue to threaten both economic output and the nascent carbon market in the world’s largest archipelago economy.

Other Economic Notes (continued)

Malaysia’s renewed currency swap with Japan and push for local-currency settlements should support reserve management and reduce USD dependence. Broader supply-chain shifts from China remain a structural positive for Vietnam and Malaysia manufacturing sectors. Indonesia’s IDRX stablecoin launch on Celo expands rupiah reach in digital finance.

Global Macro News

The Indonesian rupiah showed relative resilience as the US dollar softened ahead of the Federal Reserve’s rate decision. Brent’s 2.90% drop to 105.60 eased imported inflation pressures for oil-dependent ASEAN importers. Gold’s 0.70% decline to 4,302.50 reflected reduced safe-haven demand, while Bitcoin edged 0.08% higher.

Regional central banks continue to monitor capital-flow volatility tied to US policy signals. Malaysia’s swap renewal with Japan provides an additional buffer against external shocks. Thailand’s export-linked growth upgrade highlights the benefits of US-China supply-chain diversification for ASEAN manufacturers.

Overall, the global backdrop remains supportive for commodity and manufacturing exporters in the region provided US rates do not surprise higher.

ASEAN Central Banks Watch

Indonesia’s new finance minister faces the task of restoring fiscal credibility while Bank Indonesia maintains its focus on rupiah stability through potential FX intervention. ↓ p.3

Continuation

ASEAN Central Banks Watch (continued)

Malaysia’s central bank is testing ringgit stablecoins with major banks and has renewed its swap line with Japan to promote local-currency trade settlement. Thailand’s Bank of Thailand has not altered its policy stance, with the committee voting to hold amid the upgraded growth outlook. The Philippines’ BSP continues to balance remittance inflows against imported inflation risks.

Singapore’s MAS manages policy exclusively through the Singapore dollar NEER band, with no interest-rate tool in use. Vietnam’s SBV maintains reserve adequacy as a priority while attracting FDI from supply-chain shifts. Policy divergence remains evident, with BI most active on currency defense and MAS relying on exchange-rate flexibility.
