Yesterday's Recap

Indonesia dominated regional news flow after President Prabowo removed the finance minister and elevated the deputy, triggering investor questions over fiscal direction. The JCI slipped 0.10 percent to 6,534.69 while USD/IDR rose 0.29 percent to 17,682 amid the political shift and higher oil prices. Malaysia’s KLCI advanced 0.67 percent to 1,698.01 and Singapore’s STI gained 0.39 percent to 5,718.02, providing limited offset.

USD/MYR jumped 1.00 percent to 4.08, USD/THB climbed 0.42 percent to 33.23, USD/PHP added 0.12 percent to 62.77 and USD/SGD rose 0.41 percent to 1.27 as the dollar strengthened. Thailand’s 2026 growth projection was lifted to 2.5 percent from 2 percent on stronger exports and investment inflows. Indonesia’s external debt reached US$454.8 billion in July, keeping external financing needs in focus.

No macro data releases occurred across the six ASEAN economies on 14 September. Regional equities showed mixed performance while Brent crude surged 2.67 percent to 108.50, adding pressure on oil-importing economies, and gold fell 0.43 percent to 4,333.40.

The Day Ahead

Malaysia will release August inflation figures on 17 September, with the year-over-year rate expected to hold at 1.8 percent. No central-bank meetings, bond auctions or major data prints are scheduled for 15-16 September across Indonesia, Thailand, Philippines, Singapore or Vietnam. Traders will monitor any follow-up statements from Jakarta on fiscal leadership changes.

Regional equity and FX desks remain focused on oil-price volatility and US dollar direction. MAS will continue managing the Singapore dollar NEER band without an interest-rate decision. Thailand’s upgraded growth outlook highlights improving external demand that could support manufacturing and tourism recoveries while Malaysia’s renewed currency-swap arrangement with Japan and stablecoin testing underscore efforts to deepen local-currency settlement channels.

Other Economic Notes (continued)

Broader ASEAN supply-chain shifts continue to favor Vietnam and Malaysia as alternative manufacturing sites amid ongoing China-US trade realignment. Remittance-dependent Philippines and commodity-linked Indonesia face differing sensitivities to global risk sentiment. Supply-chain diversification away from China continues to channel FDI toward Vietnam and Malaysia, supporting medium-term growth differentials.

Global Macro News

Brent crude’s surge to 108.50 adds imported inflation pressure on oil-dependent ASEAN economies and widens current-account gaps in Indonesia and Thailand. The stronger US dollar lifted most regional pairs, with USD/MYR posting the largest daily move at 1.00 percent. Gold’s 0.43 percent decline to 4,333.40 offered little safe-haven support for local assets.

Bitcoin’s 3.54 percent drop to 75,400 reflected broader risk-off flows that can curb portfolio inflows into ASEAN equities. Global investors are watching US policy signals and Chinese demand indicators for clues on export orders to the region. Higher oil prices also raise the likelihood of delayed monetary easing across import-heavy central banks.

ASEAN Central Banks Watch

BI faces renewed rupiah pressure following the finance-ministry change and will likely maintain its hawkish bias to defend reserves. BoT is expected to keep policy steady as the upgraded growth forecast reduces the urgency for further accommodation. ↓ p.3

Continuation

ASEAN Central Banks Watch (continued)

BNM continues testing ringgit stablecoins with major banks while renewing its currency-swap line with Japan to promote local-currency trade settlement. BSP monitors remittance and inflation trends without an immediate meeting on the calendar. MAS will adjust the Singapore dollar NEER band as needed rather than relying on interest-rate changes.

SBV maintains its focus on credit growth and FDI inflows to sustain Vietnam’s manufacturing momentum. Policy divergence remains evident, with BI more active on FX intervention while MAS and BNM emphasize exchange-rate and liquidity tools.
