Southeast Asia moves a lot of money across borders. Not in headlines — the Gulf corridors get those — but in the quiet, persistent flows that finance the region's informal economy, fund regional businesses, and support families spread across six countries.
Singapore is the hub. With a foreign workforce comprising roughly 38% of its total labour force and a position as the region's financial centre, Singapore is the origin point of enormous cross-border flows into Malaysia, Indonesia, the Philippines, Vietnam, and Thailand. Malaysia is the second node — it hosts approximately 1.7 million documented foreign workers (and a significant undocumented population) primarily from Indonesia and Bangladesh, while simultaneously exporting capital to Singapore and the Gulf.
The ASEAN remittance market is estimated at US$50–70 billion annually in person-to-person flows. The cost of moving that money — through bank wire fees, exchange rate margins, and processing delays — represents a multi-billion-dollar inefficiency that the region's payment infrastructure is only beginning to address.
This is the guide for the person sitting in Singapore who needs to move money to family or contractors in Vietnam. Or the Malaysian entrepreneur paying suppliers in Indonesia. Or the Indonesian domestic worker in Singapore sending home every two weeks.
Southeast Asian cross-border payments have three structural problems that make them more expensive than they should be:
Fragmented currencies. Six different currencies — SGD, MYR, IDR, PHP, VND, THB — each with independent central bank policy, different liquidity profiles, and exchange rate dynamics that don't move together. Each currency pair requires its own liquidity management from transfer platforms, which drives up costs.
Underdeveloped interbank rails. Unlike the US or EU, ASEAN does not yet have a unified interbank settlement system. ASEAN's Project Nexus (expected full rollout 2027) will link PayNow, PromptPay, DuitNow, InstaPay, and BI-FAST. Until then, cross-border payments between ASEAN countries often route through correspondent banking chains that add 1–3 days and US$15–25 in fees per transaction.
High corridor fragmentation. The SGD-VND corridor is completely different infrastructure from SGD-IDR. Each requires separate platform investment. Most fintechs have built SGD-to-Philippines and SGD-to-India well. SGD-to-Vietnam and SGD-to-Indonesia are harder — less competition, higher effective fees.
SGD → PHP (Singapore to Philippines): Well-served. Singapore has approximately 200,000+ Filipino workers. The infrastructure is mature — GCash integration, multiple competing platforms, competitive rates. This is the corridor where rate shopping is most rewarding.
SGD → IDR (Singapore to Indonesia): Large volume (Singapore hosts 250,000+ Indonesian workers, primarily in domestic service), but the rupiah's volatility and Bank Indonesia's licensing requirements have kept competition lower than SGD-PHP. Exchange rate margins are typically 1.5–2.5%.
SGD → VND (Singapore to Vietnam): Growing corridor. Vietnam's 3,000+ students in Singapore plus a growing professional community drives flows. Wise has entered this corridor; some platforms have limited Vietnam coverage.
SGD → MYR (Singapore to Malaysia): The highest-volume corridor — the Johor Bahru–Singapore commuter economy alone generates enormous cross-border flows. This is also the most competitive corridor: near-zero spreads available via PayNow-DuitNow linkage for bank-to-bank transfers.
MYR → IDR (Malaysia to Indonesia): Dominated by Indonesian domestic workers in Malaysia. High volume, historically expensive. Fintech penetration is lower because of the digital access profile of the demographic.
SGD → THB (Singapore to Thailand): Smaller personal volume. More relevant for business payments and tourism. PayNow-PromptPay linkage (live since 2021) has made SGD-THB one of the cheapest corridors in the region.
Wise — Mid-market rate, transparent flat fee. Available in Singapore (SGD send) and Malaysia (MYR send). Covers PHP, IDR, VND, THB as destination currencies. The rate transparency advantage is particularly significant for SEA corridors where exchange rate markups tend to be larger than Gulf corridors.
Instarem — Singapore-headquartered, built for the SEA market. Strong coverage across all major ASEAN corridors. GCash delivery for Philippines. WeChat Pay delivery for some Chinese corridors. AmassPoints loyalty scheme.
Wise Business — For Singapore-registered companies paying contractors or suppliers across SEA. Multi-currency account with local account details, batch payment capability, API integration. The most efficient infrastructure for recurring B2B cross-border payments in the region.
Remitly — Strong Philippines coverage from Singapore. Economy tier is the cheapest; Express tier adds speed.
GCash — For Singapore-to-Philippines specifically, GCash's international remittance product allows direct wallet-to-wallet transfers. Recipients can use the funds immediately without a bank account. Limited to the Philippines corridor.
Nium — B2B focused. Singapore-based real-time payments infrastructure that powers several other platforms. Not direct-to-consumer but worth knowing if you're building payment flows into products.
SGD → PHP (Philippines)
| Service | Fee | Rate (approx.) | PHP Received | Speed |
|---|---|---|---|---|
| Wise | ~SGD 3–5 | Mid-market (~₱41.5) | ~₱20,500–20,620 | 1–2 days |
| Instarem | ~SGD 3 | ~₱41.3 | ~₱20,500–20,540 | 1–2 days |
| Remitly (Economy) | SGD 0–2 | ~₱41.0 | ~₱20,480–20,500 | 3–5 days |
| DBS Remit | SGD 0 | ~₱40.5 | ~₱20,250 | 1–2 days |
The most important structural change in SEA cross-border payments is the bilateral QR code linkage network that has been built since 2021. Singapore's PayNow is now linked to:
These linkages are bank-infrastructure level — meaning most Singapore bank apps (DBS, OCBC, UOB) can make these transfers for free or near-free. For the SGD-MYR and SGD-THB corridors specifically, it is difficult for commercial transfer platforms to compete on price against a free government-backed infrastructure.
The remaining corridors (SGD-PHP, SGD-IDR, SGD-VND) don't yet have bilateral payment linkages. Project Nexus aims to extend the network to the Philippines, Indonesia, and Vietnam by 2027. Until then, those corridors remain commercially served territory where Wise and Instarem can compete on rate.

Singapore-registered entities paying contractors or suppliers across SEA should evaluate Wise Business before any other option. The specific advantages:
For an agency or consultancy paying 10–15 contractors across ASEAN monthly, Wise Business reduces the administrative and fee burden significantly versus running individual bank wires.
The SGD-to-ASEAN corridor has a fundamental tension: the best rates go to people with Singapore bank accounts and digital-first recipients. The Indonesian domestic worker sending money home via a Singapore-issued payroll card to a recipient without a bank account (still a significant percentage of rural Indonesian recipients) cannot access Wise's advantages.
For that segment, the traditional solution — cash collection at Singapore money changers or Mustafa Centre cash counters — remains the default. The fee for this convenience (exchange rate spread, handling fee) is real, persistent, and largely invisible in fintech-focused coverage.
For Singapore residents with bank accounts: - SGD → MYR or THB: Use PayNow → DuitNow/PromptPay via your bank app. Free, instant. - SGD → PHP, IDR, VND: Wise for rate-optimal bank-to-bank transfers. Instarem as alternative with AmassPoints upside. - SGD → PHP to GCash recipient: Instarem (direct GCash delivery) or Remitly.
For Singapore-registered businesses paying regional contractors or suppliers: - Wise Business for the multi-currency account infrastructure. Set up once, use for every currency pair.
For Malaysia-based senders: - Wise (MYR send) for Indonesia and Thailand corridors. Check if MYR→IDR is covered before signing up. - Instarem as alternative with similar rate profile.
The window to save meaningfully on SEA cross-border transfers is open now, before Project Nexus compresses rates further by commoditising the remaining corridors. Companies and individuals who build good payment habits today will enter 2027 with infrastructure already optimised.
