Ringgit, Rupiah Seen Outperforming on Softer Dollar

Southeast Asian currencies are unlikely to move in lockstep in the second half of 2026, with a weaker US dollar expected to favor Malaysia’s ringgit and Indonesia’s rupiah more than the Vietnamese dong, Thai baht and Philippine peso.
That matters because a broad dollar pullback does not automatically translate into a uniform rally across ASEAN. For investors, the key trade is no longer just “short dollar, long Asia,” but which local economies have enough yield support, external balance strength and policy credibility to outperform when the greenback eases.
The latest signals point to a softer dollar backdrop. Adalytica’s US Dollar Trade Signals snapshot shows neutral sentiment at 44 and awareness at 54, while the 30-day change has slid 56 points. FX volatility signals have also collapsed to “Extreme Fear,” with sentiment at 7, suggesting the market is pricing a quieter but still fragile currency regime.
Within that setup, the ringgit and rupiah look better positioned to catch a dollar decline. Malaysia and Indonesia tend to benefit more when global risk appetite steadies and USD demand fades, while the dong, baht and peso face a more mixed mix of domestic growth, trade and policy constraints that can limit upside even in a weaker-dollar environment.
The divergence matters for capital flows. A cleaner upside case in the ringgit and rupiah can draw selective carry and portfolio interest, while lagging peers may underperform if investors rotate toward currencies with stronger terms of trade, higher real yields or more credible policy buffers.
The market backdrop is also consistent with that split. ASEAN foreign exchange volatility remains subdued even as broader global stability sentiment is stuck at extreme fear, underscoring an environment where cross-currency dispersion can widen without a dramatic regional shock.
For investors, that means ASEAN currency exposure in late 2026 is more likely to reward relative-value positioning than broad index bets. The next catalyst will be how far the dollar weakens into the second half, and whether local central banks and trade balances reinforce, or offset, that move.
