Yesterday's Recap

Malaysia reported inflation at 0.0% MoM and 1.8% YoY, below the prior 1.9% reading and signaling contained price pressures. Thailand posted GDP growth of -0.2% QoQ against a consensus of -0.6% and 1.9% YoY versus 1.7% expected, confirming softer momentum in the second quarter. Indonesia’s rupiah traded near 17,851 per dollar with a modest 0.12% weakening, while external debt reached $453.4 billion.

Equity markets showed divergence: Indonesia’s JCI rose 1.59% to 6,401.89, Singapore’s STI gained 0.43% to 5,768.46, and Malaysia’s KLCI slipped 0.09%. The ringgit strengthened 0.67% to 4.06 per dollar on reduced Fed hike expectations, and the Thai baht firmed 0.15% to 33.08. Brent crude edged up 0.44% to 91.27 while gold fell 0.64% to 4,389.50.

Thailand’s second-quarter growth ranked lowest among major Southeast Asian peers as higher energy prices weighed on activity. Thai bank lending rose 2.0% in the quarter with bad loans edging lower, pointing to selective credit improvement.

The Day Ahead

Bank Indonesia’s monetary policy committee meets tonight with consensus pointing to a hold at 5.75%, extending the pause as external debt and rupiah stability remain focal points. No other high-impact data releases are scheduled across the six ASEAN economies today. Market participants will monitor any accompanying statement for signals on capital-flow management and reserve adequacy.

Thailand’s ongoing tourism and manufacturing softness may keep BoT commentary in focus later this week. Regional FX desks will track USD/IDR and USD/MYR reactions to the BI decision and any shifts in US rate expectations. The ringgit’s recent gains on easing Fed hike odds provide a supportive backdrop for BI’s steady stance.

Other Economic Notes

Indonesia’s July trade surplus widened on stronger nickel and coal shipments, supporting the external balance ahead of the BI meeting. Vietnam continues to attract FDI in electronics and semiconductors, with northern provinces recording record approvals driven by Taiwanese and Korean projects. Malaysia’s second-quarter lending growth reached 2.0% while non-performing loans edged lower, indicating improving credit conditions.

Thailand’s industrial production remained flat, highlighting persistent weakness in auto and electronics supply chains. <i>↓ p.2</i>

Other Economic Notes (continued)

Broader ASEAN supply-chain re-routing from China remains a structural theme, with Malaysia and Singapore semiconductor readings due later this week. Negotiators highlighted commitment to expanding US-Thailand investment and balanced trade.

Global Macro News

Easing US rate-hike expectations provided tailwinds for emerging-market currencies, notably lifting the ringgit and supporting regional equity inflows. Brent crude’s modest advance reflected OPEC+ supply signals, adding to energy-price pressures already visible in Thailand’s GDP outcome. Gold’s decline suggested reduced safe-haven demand amid stabilizing risk sentiment.

Bitcoin held near 64,533 with negligible movement, offering little directional cue for ASEAN risk assets. Brazil’s softer Q2 data echoed the mixed growth picture across emerging markets, keeping global growth concerns alive. UK stagnation signals reinforced the narrative of divergent developed-market trajectories that indirectly influence ASEAN capital flows.

Overall, the global backdrop favors selective ASEAN currency strength where domestic data outperform.

ASEAN Central Banks Watch

Bank Indonesia is widely expected to keep the benchmark rate at 5.75%, extending its pause as the rupiah stabilizes and external debt metrics are monitored. The committee will focus on inflation dynamics and reserve adequacy rather than immediate easing. Bank of Thailand is likely to maintain its dovish stance to counter tourism and manufacturing softness, with analysts noting the recent baht rally may fade under continued accommodative policy.

Bank Negara Malaysia faces less pressure after the inflation print and ringgit gains, allowing it to stay on hold. Bangko Sentral ng Pilipinas continues to balance remittance inflows against peso volatility. MAS will adjust its Singapore dollar NEER band as needed rather than interest rates, preserving its unique policy framework.

State Bank of Vietnam remains focused on supporting manufacturing FDI while managing credit growth. Policy divergence across the six central banks persists, with BI and BoT leaning defensive and MAS relying on exchange-rate tools.
