- Thailand Q1 GDP beats forecasts at 2.8% YoY while Malaysia inflation rises to 1.9% YoY
- Rupiah slumps to fresh record low of 17,714 per USD on oil-driven pressures
- Regional equities fall with JCI down 1.85% as BI rate call looms
Yesterday's Recap
Thailand reported stronger-than-expected Q1 GDP growth of 2.8% YoY against a 2.2% consensus and 0.7% QoQ versus 0.1% expected, lifting the SET index marginally. Malaysia's April inflation rose to 1.9% YoY and 0.4% MoM, confirming price pressures in the largest manufacturing economy. Indonesia's JCI dropped 1.85% to 6,599.24 while the rupiah weakened 0.73% to a record 17,714 per USD amid Brent crude near $111.
KLCI fell 0.72% and PSEi slipped 0.59% as investors positioned ahead of the BI meeting. Singapore's STI posted a modest 0.15% gain, providing limited regional offset. President Prabowo dismissed day-to-day rupiah concerns even as economists highlighted structural imbalances and high oil prices stoking imported inflation.
The Day Ahead
Bank Indonesia will announce its policy rate decision this evening with consensus pointing to a 25 bp hike to 5.00%. Markets will scrutinize any accompanying FX intervention signals or reserve management updates. No other major data releases are scheduled across ASEAN today.
Thailand may see continued commentary on its Q1 growth beat and upcoming cost-of-living measures. Malaysia's latest inflation print keeps BNM in focus for any subtle hawkish shifts.
Other Economic Notes
Elevated Brent prices near $111 are amplifying imported inflation risks for net energy importers such as Thailand and the Philippines. Supply-chain relocation continues to support Malaysia's manufacturing PMI and Vietnam's electronics exports. Indonesia's persistent current-account and fiscal pressures leave the rupiah more exposed than regional peers during dollar strength episodes.
Thailand's tourism rebound and Malaysia's external demand resilience offer partial buffers.
Global Macro News
A firmer USD on softer US data has weighed on ASEAN currencies outside the SGD. Brent's surge above $110 reflects ongoing Middle East supply concerns that directly hit ASEAN current accounts. South Korean and Taiwanese assets also slipped, underscoring broader EM risk aversion.
Gold and Bitcoin retreated, reducing safe-haven flows into the region. US supply-chain scrutiny on forced labour adds uncertainty for Thai and Vietnamese exporters. Overall global liquidity conditions remain tighter than earlier in the year, limiting capital inflows to higher-yielding ASEAN bonds.
