Singapore, Malaysia and Thailand central banks expand cross-border stablecoin initiative involving Ripple, Visa and Mastercard

Introduction

The monetary authorities of Singapore, Malaysia and Thailand have announced the next phase of their BLOOM initiative, a cross‑border settlement platform that uses stablecoins and tokenised deposits. Building on the pilot that linked Singapore’s central bank digital currency (CBDC) with Ripple’s settlement network, the expansion brings Malaysia and Thailand into the ecosystem and formalises partnerships with major payment processors such as Visa and Mastercard. The move signals a coordinated regional effort to modernise inter‑bank payments, reduce settlement friction, and lay groundwork for broader digital‑currency interoperability in Southeast Asia.

Expanding the participant base

The original BLOOM framework was designed to enable Singapore‑based banks to settle cross‑border transactions instantly using a regulated stablecoin anchored to the Singapore dollar. By onboarding the central banks of Malaysia and Thailand, the network now supports three fiat currencies—SGD, MYR and THB—under a single technical architecture. Each central bank will issue its own tokenised deposit, backed by reserves, that can be exchanged on‑chain with the other participants. This multi‑currency capability is expected to streamline trade finance, remittances, and tourism‑related payments across the region.

Role of Ripple, Visa and Mastercard

Ripple continues to provide the underlying distributed‑ledger technology that powers the stablecoin settlement layer. Its protocol enables near‑real‑time finality while preserving the regulatory controls required by central banks. Visa and Mastercard are joining as payment‑network partners, offering their existing merchant‑acquisition and card‑issuance infrastructure to bridge the on‑chain settlement layer with traditional point‑of‑sale and online payment flows. Their involvement is intended to broaden the reach of the stablecoin beyond wholesale banking, allowing retailers and consumers to benefit from faster, lower‑cost cross‑border payments.

Operational and regulatory safeguards

All three central banks have committed to a shared governance model that includes:

• Joint oversight committee: Representatives from each authority will monitor system performance, risk metrics, and compliance with anti‑money‑laundering (AML) and counter‑terrorism financing (CTF) standards.
• Reserve backing: Each tokenised deposit will be fully collateralised by sovereign reserves, with regular audits published to maintain market confidence.
• Interoperability standards: The initiative adopts the ISO 20022 messaging format and aligns with the BIS Innovation Hub’s standards for CBDC interoperability, ensuring that future participants can join without extensive re‑engineering.

Expected impact on regional payments

Analysts anticipate several tangible benefits:

• Speed: Settlement times shrink from days to seconds, reducing liquidity strain for banks that previously relied on correspondent‑bank networks.
• Cost reduction: Lower transaction fees and reduced foreign‑exchange spreads could translate into savings for businesses engaged in ASEAN trade.
• Financial inclusion: By linking the stablecoin to existing card networks, smaller merchants and consumers gain access to faster cross‑border payment options without needing a dedicated bank account.

Practical next steps

The expanded BLOOM network will move from a controlled pilot to a phased rollout over the next 12‑18 months. Early adopters—primarily large corporates and banks with significant ASEAN exposure—will be invited to test end‑to‑end flows. Meanwhile, the central banks will publish detailed technical specifications and compliance guidelines to assist fintech firms and payment service providers in integrating with the platform.

--- The expansion of BLOOM underscores a growing consensus among Southeast Asian regulators that digital‑currency infrastructure can coexist with, and enhance, traditional payment systems. By leveraging established fintech partners and adhering to rigorous oversight, the initiative aims to set a pragmatic blueprint for cross‑border stablecoin adoption worldwide.
