Yesterday's Recap

Indonesia dominated the ASEAN tape as the rupiah weakened 0.39% to 18,140/USD, with foreign outflows and mixed economic figures pressuring the currency despite Bank Indonesia highlighting a September trade surplus as an economic buffer. Jakarta equities followed FX lower, with the JCI shedding 0.80% to 5,057.05. Elsewhere in the region, Malaysia's KLCI edged up 0.28% to 1,615.60 as the ringgit opened firmer on expectations of policy normalisation ahead of Bank Negara's decision, though USD/MYR still drifted 0.28% higher to 4.07.

Singapore's STI slipped 0.36% to 5,376.74, and the peso firmed 0.34% to 63.38/USD even as IntelliNews flagged the Philippines and Indonesia as Asia's weakest currencies facing further rate hikes. The baht was essentially flat at 33.71/USD, with Commerzbank and DBS both noting a cautious BoT stance and persistent downside risks. Regional bond markets were quiet, with 10-year yields in Indonesia and Thailand unchanged on the day.

The Day Ahead

The ASEAN calendar is light to start the week, with no scheduled tier-one data releases across the six economies. Attention instead pivots to Malaysia, where markets are positioning for Bank Negara's overnight policy rate decision later this week, with the ringgit expected to trade in a narrow range against the dollar in the interim. Indonesian markets will continue to digest the rupiah's slide and monitor foreign flow dynamics, with BI's next policy meeting not due until November 18.

Singapore traders will watch for any MAS commentary on the NEER band as regional FX volatility persists. Thailand's focus remains on the BoT's growth-forecast upgrade and its cautious normalisation path, with no fresh data on the docket.

Other Economic Notes

The collapse in Brent crude of 11.40% to $104.23 is the dominant cross-asset theme, a sharp reversal that relieves imported inflation pressure for net energy importers like Thailand and the Philippines but squeezes Malaysia's and Indonesia's hydrocarbon revenues. Gold's 1.48% rally to $3,956.60 signals persistent risk aversion, consistent with the foreign outflows pressuring Indonesian assets. Bitcoin's 2.01% drop to 76,678.85 underscores the broader de-risking tone.

Other Economic Notes (continued)

For ASEAN, the oil move is a meaningful terms-of-trade swing that could ease subsidy burdens in Indonesia and Thailand while complicating fiscal assumptions in Malaysia. Singapore, as the region's financial hub, will feel the cross-asset volatility most acutely through its wealth-management and FX channels.

Global Macro News

Global markets are in a defensive posture, with the sharp oil selloff and gold rally pointing to shifting risk appetite and repositioning around energy fundamentals. The US election cycle is injecting volatility into Asian asset markets, with Bursa Malaysia explicitly bracing for a volatile week tied to US political developments and the BNM decision. The peso and rupiah leading Asia's currency slide reflects a broader dollar-strength and capital-flight dynamic across emerging markets.

Commerzbank and DBS both flag persistent downside for the baht as the BoT stays cautious on normalisation, suggesting regional central banks remain wary of premature easing. The oil collapse may temper global inflation expectations, potentially easing pressure on Asian central banks, though the demand signal behind the drop bears watching. For ASEAN exporters, weaker global risk sentiment and softer commodity prices pose headwinds to trade and FDI flows into year-end.

ASEAN Central Banks Watch

Bank Indonesia holds its policy rate at 5.75%, set at the June 18 decision and reaffirmed at the October 21 hold, with the next meeting on November 18; BI is actively defending the rupiah amid foreign outflows, and IntelliNews flags the possibility of further hikes given the currency's slide. ↓ p.3

Continuation

ASEAN Central Banks Watch (continued)

The Bank of Thailand kept rates unchanged at 1.00% at its October 28 decision, with the next meeting December 23; the BoT raised growth forecasts but warned recovery remains concentrated, and analysts see a cautious normalisation path with curve-steepening risks. Bank Negara Malaysia's policy rate stands at 2.75%, with markets anticipating a decision this week and the ringgit firming on normalisation expectations. The BSP faces pressure as the peso leads Asia's slide, with IntelliNews suggesting more rate hikes may be needed.

MAS, which targets the NEER band rather than interest rates, will be watching regional FX volatility closely. The SBV in Vietnam remains focused on managed dong stability and credit-growth management, rounding out a region where policy divergences are widening as FX defence dominates the agenda.
