  • Indonesia’s rupiah hits fresh lows at 17,878 per USD amid BI dollar purchase curbs and global uncertainty.
  • Thailand posts record $7.6bn current account deficit in April, raising dual deficit risks and baht pressure.

Yesterday's Recap

Indonesia dominated ASEAN moves as the rupiah weakened to a record 17,878 per USD, up 0.21%, prompting Bank Indonesia to tighten dollar purchase rules and cite global uncertainty. Stocks and bonds tumbled with JCI closing at 6,127.38, down 0.05%. Thailand reported a record $7.6bn current account deficit in April, driven by slowing growth and rising imports, sparking debate over longer-term baht weakness.

Malaysia’s official reserve assets rose to US$129.73bn at end-April. The Philippines saw USD/PHP climb 1.25% to 61.48 while Singapore’s STI gained 0.98% to 5,037.86. Brent crude dropped 2.76% to $91.12 and gold rose 2.08% to $4,593.

Vietnam and Malaysia showed limited moves outside reserve and FDI updates.

The Day Ahead

Indonesia will release May trade balance and inflation data on June 2, with consensus pointing to inflation near 2.97%. Philippines inflation for May prints on June 4, following the prior 7.2% reading. No central bank meetings are scheduled across the six ASEAN economies today.

Thailand’s bond auction and corporate earnings remain the only other items on the calendar. Markets will watch USD strength and oil price swings for spillover effects on regional FX.

Other Economic Notes

Indonesia’s squeezed middle class faces higher import costs from the weak rupiah, shifting consumption patterns. Thailand’s tourism recovery continues to offset part of the current account deterioration but cannot fully mask slowing domestic demand. Malaysia’s rising reserves provide a buffer against ringgit pressure yet fail to reverse structural outflows.

Broader ASEAN supply-chain shifts from China remain supportive for Vietnam and Malaysia manufacturing FDI.

Global Macro News

Persistent USD strength continues to pressure ASEAN currencies, especially the rupiah and peso. Brent crude’s 2.76% decline eases imported inflation risks for oil-dependent importers like Thailand and Philippines. Gold’s 2.08% rally signals ongoing safe-haven demand amid global uncertainty.

Global Macro News (continued)

Central bank meetings elsewhere, including the Bank of Japan, are expected to shape near-term risk sentiment. US pressure on allies to raise defense spending has limited immediate impact on Malaysia’s budget plans. Supply-chain diversification away from China supports longer-term FDI inflows into Vietnam and Malaysia.

ASEAN Central Banks Watch

Bank Indonesia tightened dollar purchase rules to defend the rupiah while keeping policy rates on hold, citing global uncertainty and still-contained inflation. The Bank of Thailand is expected to maintain its current stance given absent inflationary pressure despite the record current account deficit. Bank Negara Malaysia left rates unchanged with reserves at US$129.73bn providing adequate cover.

Bangko Sentral ng Pilipinas faces reduced urgency for near-term easing after softer Q1 growth. MAS will next review the S$NEER slope in July with no change anticipated. State Bank of Vietnam continues to manage liquidity to support export-led growth without rate adjustments.

Policy divergence remains evident, with BI most active on FX intervention while others stay on hold.
