Unlocking Stablecoins’ Potential for RTGS Systems

The rise of stablecoins, a form of digital currency pegged to fiat or other stable assets, has redefined the landscape of financial innovation. Originally introduced to counter the volatility of traditional cryptocurrencies, stablecoins are now paving the way for real-time stablecoin settlement in critical financial systems like RTGS transfers.

In this article, we explore how stablecoins can integrate with real-time gross settlement (RTGS) systems to improve transaction efficiency, reduce costs, and enhance transparency. All this, while maintaining compliance and financial stability.

What Are Real-Time Gross Settlement (RTGS) Systems?

RTGS systems are the core infrastructure of modern finance. Used by central banks and financial institutions worldwide, these systems facilitate the immediate settlement of high-value payments, processed individually and in real time. Each transaction is settled on a gross basis, meaning funds are transferred directly between parties without netting or batching.

By eliminating settlement delays and counterparty risk, RTGS systems provide a foundation of trust and liquidity in the financial ecosystem. However, they are not without limitations, particularly around speed, reconciliation complexity, and operational costs.

The Role of Stablecoins in Modernising RTGS Transfers

Stablecoins present a compelling opportunity to augment RTGS operations through programmable, blockchain-based infrastructure. Their consistent value and interoperability with distributed ledger technology (DLT) make them suitable for real-time, high-value transfers.

1. Real-Time Stablecoin Settlement

Unlike traditional RTGS systems that depend on centralised clearing and reconciliation layers, stablecoin-based RTGS can execute settlements within seconds. This real-time capability helps improve liquidity management, especially for institutions handling time-sensitive transactions.

By embedding smart contracts, stablecoin transactions can also be programmed for compliance triggers, execution windows, and real-time reporting. These features reduce post-trade friction and manual intervention.

2. Reduced Costs and Fewer Intermediaries

A traditional RTGS transfer often involves fees related to correspondent banking, FX conversion, and SWIFT infrastructure. Stablecoins remove many of these layers by enabling peer-to-peer transfers via blockchain networks, eliminating the need for intermediaries.

For financial institutions processing large volumes of high-value payments, the cost savings are significant, especially across borders where legacy settlement systems introduce complexity and fees.

3. Improved Transparency and Regulatory Oversight

Stablecoin-based RTGS systems built on DLT offer traceable and immutable records of every transaction. Regulators and central banks benefit from real-time auditability, automated compliance checks, and reduced risk of fraud or manipulation.

This level of transparency also aligns with increasing regulatory expectations around anti-money laundering (AML), counter-terrorist financing (CTF), and Know Your Customer (KYC) requirements.

RTGS Challenges vs Stablecoin Solutions

‍

Key Challenges to Address

While the potential of stablecoins in RTGS is immense, there are critical hurdles that must be addressed to enable wide-scale adoption.

1. Regulatory Readiness and Risk Management

The integration of stablecoins into RTGS frameworks requires clear regulatory guidance and robust risk frameworks. This includes:

• Licensing and oversight of stablecoin issuers
  
  
• Reserve management and auditability of backing assets
  
  
• Strong safeguards around cybersecurity, consumer protection, and systemic risk mitigation
  
  

2. Central Bank Collaboration

For stablecoins to become a trusted part of real-time financial infrastructure, coordination with central banks is essential. Initiatives like central bank digital currencies (CBDCs) and Project Orchid in Singapore show the potential for synergy between stablecoin models and public-sector oversight.

Hybrid models, where regulated stablecoins settle against central bank money or work alongside CBDCs, can provide innovation and stability together.

3. Scalability and Interoperability

A fragmented ecosystem of proprietary blockchains or stablecoins could hinder efficiency. RTGS systems require scalable architecture and seamless interoperability between institutions, networks, and currencies.

This means developing:

• Shared messaging standards such as ISO 20022
  
  
• Cross-chain bridges for multi-asset transfers
  
  
• API-first infrastructure for integration with core banking systems
  
  

Platforms like StraitsX are already addressing these gaps by enabling direct minting and redemption of regulated stablecoins like XSGD and XUSD. They also support interoperability with other leading digital assets.

Real-World Implications for Financial Institutions

The convergence of stablecoins and RTGS systems is more than a technological improvement. It is a shift toward smarter, programmable settlement. For banks, payment service providers, and clearing houses, this can mean:

• Reduced reconciliation timelines and fewer failed transactions
  
  
• Instant liquidity and better intraday cash management
  
  
• Compliance automation and stronger data lineage for audits
  
  
• New financial products built on on-chain RTGS capabilities, such as automated escrow or programmable syndicated loans

In emerging markets where RTGS systems are still developing, stablecoin integration can help leapfrog legacy limitations. This makes it possible to build advanced infrastructure with lower setup and operating costs.

Looking Ahead: RTGS in a Tokenised Future

As more financial institutions experiment with digital asset rails, the line between traditional RTGS and decentralised systems will continue to blur. Stablecoins could eventually serve as interoperable liquidity tools across multiple networks, creating a global settlement layer that is both programmable and compliant.

With increasing support from policymakers and market infrastructure providers, the use of stablecoins in RTGS is no longer theoretical. It is a near-future reality that will redefine how money moves in a digital-first world.

Conclusion: A New Era of RTGS Is Within Reach

Stablecoins are more than a parallel financial instrument. They are a core enabler of next-generation settlement infrastructure. By combining the reliability of RTGS with the speed and programmability of blockchain, the financial industry can unlock real-time value transfer that is scalable, auditable, and inclusive.

To realise this potential, stakeholders must address regulatory, technical, and operational barriers. With thoughtful design and collaboration, stablecoin-powered RTGS systems can become the future foundation of global finance. They will be faster, more cost-efficient, and more responsive to a digital-first economy.
