Project Nexus 2026: How ASEAN's Real-Time Payment Revolution Changes Cross-Border Business

What is Project Nexus?

Project Nexus is the most ambitious cross-border payment infrastructure project in a generation. Led by the Bank for International Settlements (BIS) Innovation Hub, it connects the instant payment systems of five founding countries — Singapore (FAST/PayNow), Malaysia (DuitNow), Thailand (PromptPay), India (UPI), and the Philippines (InstaPay) — through a single multilateral gateway.

Instead of building bilateral connections between every pair of countries (which would require 10 separate integrations for 5 countries), Nexus creates one standardized connection point. Each country connects once to the Nexus gateway, and immediately gains access to all other participating countries. When a sixth country joins, it connects once, and all existing members can transact with it instantly.

For the 1.7 billion people across these five countries, it means near-instant cross-border payments at domestic prices.

Why This Matters for Southeast Asian Businesses

The Asia-Pacific cross-border payments market totalled $12.8 trillion in 2024 and is projected to reach $23.8 trillion by 2032. ASEAN's intra-regional trade is growing at 8-12% annually, but payment infrastructure has not kept pace.

Today, a Thai small business paying a Malaysian supplier uses SWIFT — which means $30-50 in fees, 2-4% FX markup, and 3-5 day settlement. Under Project Nexus, that same payment settles in seconds, at domestic-level fees, with transparent FX rates. For SMEs operating on thin margins, this is transformative.

For businesses receiving payments from multiple ASEAN countries, Nexus eliminates the need for separate banking relationships in each market. A Vietnamese e-commerce seller receiving payments from Thai, Singaporean, and Filipino customers can settle all three through a single instant payment integration.

How Project Nexus Works Under the Hood

Nexus operates as a coordination layer between domestic instant payment systems (IPS). When a sender in Thailand initiates a payment to a recipient in Singapore, the flow works as follows:

The sender's bank debits their Thai baht account and sends a payment instruction to PromptPay. PromptPay forwards the instruction to the Nexus gateway with the recipient's PayNow identifier. Nexus validates the payment, coordinates the FX conversion through pre-contracted liquidity providers, and forwards the instruction to PayNow. PayNow credits the recipient's Singapore dollar account. Total time: under 60 seconds.

The FX conversion happens at competitive rates through pre-contracted liquidity providers who compete on price — a stark contrast to the opaque correspondent banking markups in the SWIFT system. The sender sees the exact amount the recipient will get before confirming.

What Nexus Does Not Replace

Project Nexus is designed for retail and SME payments — think amounts up to $50,000-$100,000 depending on the country's IPS limits. For large corporate treasury transfers, trade finance, and high-value transactions, SWIFT remains the dominant rail.

Nexus also does not handle securities settlement, trade documentation, or letters of credit. It is specifically a payment transfer system. Businesses with complex trade finance needs will still rely on banking relationships and dedicated trade platforms.

Initially, Nexus covers only the five founding countries. Expansion to Indonesia, Vietnam, and Cambodia is planned for 2027-2028, but regulatory alignment and infrastructure upgrades in each country take time. In the meantime, virtual bank accounts remain the fastest way to receive payments in currencies not yet covered by Nexus.

How Businesses Should Prepare

Even before Nexus reaches full scale, businesses should start positioning their payment infrastructure for real-time cross-border settlement.

First, map your ASEAN payment flows. Identify which country pairs account for the majority of your cross-border volume. If Singapore-Thailand or Singapore-India payments are significant, you can benefit from Nexus immediately at launch.

Second, set up virtual bank accounts in ASEAN currencies that Nexus does not yet cover. For PHP, MYR, IDR, and VND, virtual accounts with local clearing access provide the same speed and cost benefits as Nexus, available now.

Third, talk to your payment provider about Nexus readiness. Woalet supports virtual bank accounts across all ASEAN currencies and is preparing Nexus integration for participating countries. As the network expands, your existing multi-currency infrastructure will seamlessly connect to the real-time rails.
