Inside the MAS Sandbox: How Ripple is testing RLUSD for real trade settlements

Singapore has strengthened its position as a leading hub for tokenized finance through Project BLOOM (Borderless, Liquid, Open, Online, Multi-currency).

This collaborative initiative brings together a group of traditional banks, fintech firms and stablecoin providers to evaluate how digital settlement assets can be integrated into existing financial infrastructure.

A notable partnership in the pilot involves Ripple and supply chain specialist Unloq. Together, they are exploring automated trade settlements using Ripple’s upcoming stablecoin, RLUSD, on the XRP Ledger.

While Ripple’s inclusion may appear to signal a green light from Singaporean regulators, the reality is more measured. RLUSD is currently operating within a sandboxed environment, a structured testing phase focused on specific technical applications rather than a broad regulatory mandate.

Distinguishing between this experimental validation and official licensure is essential to accurately assess the project’s current scope and future potential.

Ripple’s pilot project under the Monetary Authority of Singapore’s (MAS) BLOOM initiative is focused on a specific challenge: automating cross-border trade settlement through programmable digital money.

The setup brings together three core elements:

XRP Ledger as the transaction infrastructure

Unloq’s SC+ system as the execution layer for trade finance workflows

Rather than simply moving funds between parties, the system is designed to release payments automatically once specific commercial conditions have been met. These conditions may include shipment confirmation, document verification or financing triggers.

RLUSD is being evaluated not just as a payment tool, but as an integrated part of a conditional settlement mechanism embedded directly into trade workflows.

Did you know? Traditional trade finance still relies heavily on paper documents such as bills of lading, which can take days or even weeks to process. Programmable settlement systems aim to digitize and automate these workflows.

The MAS launched BLOOM in October 2025 to examine how tokenized money could improve settlement processes across borders and between institutions.

The initiative extends well beyond any single participant. It includes banks such as DBS and UOB, infrastructure providers such as Partior, and stablecoin issuers including Circle. Ripple is just one participant in this broader ecosystem.

Importantly, BLOOM is not a live production system. It functions as a sandbox-style environment that allows firms to test financial innovations under regulatory oversight.

As a result, involvement in the initiative does not mean MAS has approved RLUSD as a universally accepted settlement asset. It simply indicates that MAS views the proposed use case as sufficiently promising to test in a controlled setting.

Recognizing this distinction helps avoid a common misunderstanding. Participation in a regulatory sandbox reflects supervised experimentation, not formal regulatory endorsement.

Trade finance is more complex than straightforward payments. A standard transaction typically involves multiple parties, including exporters, importers, banks, insurers and logistics providers, along with several layers of documentation and conditional obligations.

Payments are rarely executed immediately. They are tied to specific events, such as:

Traditional systems manage these interdependencies through manual procedures and intermediaries, often resulting in delays, errors and limited transparency.

Ripple’s RLUSD pilot seeks to address this complexity by embedding payment logic directly into the settlement layer. Instead of handling documents separately before releasing payments, the process takes place within a single, unified execution framework.

This approach sets the pilot apart from most stablecoin applications. It goes beyond simply speeding up money transfers. Instead, it focuses on synchronizing the movement of money with real-world commercial conditions in real time.

Did you know? Stablecoins were initially popularized as a source of liquidity in crypto trading, but regulators are increasingly exploring their role in real-world financial infrastructure, including cross-border payments and settlement systems.

Ripple’s involvement in BLOOM coincides with a separate regulatory development. In December 2025, MAS expanded the range of payment activities permitted under the Major Payment Institution (MPI) license held by Ripple’s Singapore subsidiary.

This licensing change allows Ripple to offer a broader range of regulated payment services in Singapore.

Nevertheless, the BLOOM pilot remains separate. It is not intended to license Ripple’s products for widespread use, but rather to evaluate whether a specific settlement architecture works effectively in practice.

The distinction can be outlined as follows:

MPI license expansion: Regulatory authorization for broader payment services

BLOOM pilot: Controlled testing of programmable settlement infrastructure

Confusing these two elements may overstate the regulatory significance of the pilot. BLOOM is designed to address technical and operational questions, not to select or endorse one settlement model over another.

Ripple’s pilot is part of a broader MAS effort to explore tokenized financial infrastructure across multiple areas.

In November 2025, MAS announced plans to issue tokenized MAS bills to primary dealers, with settlement facilitated through a wholesale central bank digital currency (CBDC). Around the same time, it also revised its guidance on tokenized capital market products to provide greater clarity on regulatory expectations.

These steps point to a broader approach. Rather than supporting a single type of digital money, Singapore is testing a multi-asset settlement ecosystem that includes:

Within this framework, RLUSD represents one possible settlement asset among several.

Ripple’s approach differs from other stablecoin and tokenized money experiments currently underway in several important ways:

Three elements distinguish Ripple’s pilot: conditional settlement logic, integration with trade workflows and a multi-asset environment.

Conditional settlement logic: Unlike most stablecoin pilots, RLUSD is being tested in a system where payments are contingent on real-world events. This adds a layer of programmability that extends well beyond basic transfers.

Integration with trade workflows: The pilot embeds settlement directly into trade finance processes rather than treating it as a separate function. This has the potential to reduce fragmentation across documentation, financing and payment.

Multi-asset environment: RLUSD is being evaluated alongside tokenized bank liabilities. This aligns with MAS’ broader objective of creating interoperable settlement assets rather than relying on a single dominant model.

Collectively, these elements place RLUSD within a broader experiment in programmable financial infrastructure rather than limiting it to digital payments alone.

Despite its potential, the pilot leaves several important questions unresolved:

Can trade conditions be reliably digitized and verified in real time?

Will smaller businesses actually benefit from improved access to financing?

Can stablecoins and bank issued tokens coexist without fragmenting liquidity?

How will regulatory oversight evolve if such systems move beyond the pilot stage?

These questions underscore that the pilot is not a complete solution. Rather, it is an exploration of whether a new settlement model can function effectively at scale.

Did you know? Smart contracts can reduce settlement risk by ensuring that funds move only when predefined conditions are met. This can help reduce disputes arising from mismatched documentation in international trade.

The BLOOM initiative suggests that the future of digital settlement may not be defined by any single asset type or infrastructure.

Instead, regulators such as MAS appear to be examining a layered approach in which different forms of tokenized money serve distinct roles:

Stablecoins for programmability and interoperability

Ripple’s RLUSD pilot adds to this ongoing experimentation, offering one possible model for how stablecoins could extend beyond simple payments into more sophisticated financial workflows.
