In an era where digital transformation is reshaping every aspect of global commerce, one system seems stuck in time: traditional international payments. "Rails" like SWIFT, despite serving for decades, are now revealing their inherent weaknesses: they are slow, costly, and do not operate 24/7.

Against this backdrop, two new concepts have emerged as promises for the future: Stablecoin and Central Bank Digital Currency (CBDC). Many perceive them as rivals, but in reality, they are two perfect puzzle pieces, poised to coexist and shape a modern financial ecosystem—one where money flows quickly, transparently, and legally.

This article will help you decode the role of each currency, their interconnection, and why this combination holds special significance for Vietnamese businesses on their journey to global integration.

Decoding Stablecoin and CBDC: What Are They?

To keep it simple, we won't use academic definitions, but rather simple, purpose-focused analogies.

Stablecoin can be seen as "digital currency"—a digital USD version issued by private organizations, operating on public blockchains like Ethereum or Solana. They are designed to serve cross-border transactions at near-instant speeds, low costs, and on a non-stop basis. In the world of global payments, Stablecoin is the "Formula 1 race car" – fast, powerful, and agile.

Conversely, CBDC is "digital cash" issued by the Central Bank, holding a 1:1 value with paper money and operating on a private, state-controlled network. The goal of a CBDC is not to compete, but to modernize the domestic payment system and expand financial access for all citizens. If Stablecoin is the high-speed race car, CBDC is the "city utility truck"—durable, stable, and reliable.

Stablecoin and CBDC: Competition or Complementarity?

You wouldn't use an F1 car for daily city commutes, and you wouldn't use a utility truck to compete in an international race. Each has its own mission.

Technically, Stablecoin is designed for international transactions—for example, when a Vietnamese merchant needs to receive payment from a partner in Europe or pay a supplier in Singapore. Meanwhile, CBDC is suitable for domestic transactions, such as paying employee salaries or settling invoices with local providers.

The important thing is not choosing a side, but rather figuring out how these two systems can "talk" to each other—allowing money to flow seamlessly between international and domestic rails.

The Key Challenge: "Interoperability"

Imagine a day when the F1 race car (Stablecoin) needs to transfer goods to the city utility truck (CBDC). The problem is, they run on two different roads—one is a public highway (public blockchain), the other is a private network. How can value move smoothly, legally, and safely between these two systems?

That is the "interoperability" problem—the challenge of interaction between digital financial platforms. This is not just a technical test, but also a challenge in legal frameworks, security, and governance.

Building the "Bridge" Between Two Worlds in Vietnam

Vietnam is progressively laying the groundwork to connect the Stablecoin and CBDC ecosystems—a roadmap that can be seen as a "three-step strategy" to prepare for a comprehensive payment future.

The first step is building the legal framework for digital assets. The government is gradually recognizing digital assets as a lawful asset class, with clear direction in the 2025 Law on Digital Technology and Resolution 05. This is a crucial step to ensure that, in the future, Stablecoin flows can enter Vietnam transparently and with legal protection.

In parallel, the State Bank is implementing an Open API mechanism under a sandbox model (based on Decree 94)—a standardized "payment highway" that allows businesses to connect with banks via open application programming interfaces. When this system is complete, domestic transactions will become faster, safer, and more cost-effective.

Finally, the Vietnamese government has assigned Viettel and Mobifone to research and deploy a National Digital Currency (CBDC) to promote financial inclusion. With the combination of a solid legal framework, a modern Open API infrastructure, and dedicated CBDC research, Vietnam is set to build a sustainable and advanced payment ecosystem.

When Stablecoin and CBDC "Shake Hands" – The Benefit for Your Business

Let's paint a hypothetical scenario in the near future. At 8:00 AM, your partner in the US sends 10,000 USDC. Just one minute later, this amount passes through a "licensed international payment gateway" in Vietnam. And by the second minute, that 10,000 USDC is automatically converted into e-VND and instantly updated in your bank account via the Open API infrastructure.

It all happens in two minutes. An international transaction completed instantly, ensuring legal compliance, minimal costs, and absolute transparency. That is the vision of the payment future Vietnam is heading towards—a place where global and domestic money flows are connected by synchronized technology and law.

FinTech – The "Connector" of Two Worlds

Amid these shifts, licensed FinTech companies will play the role of the "connector," acting as the bridge between Stablecoin (global, public) and CBDC (domestic, controlled) once implemented.

They are the "translators" of the two systems, enabling B2B transactions, remittances, or cross-border e-commerce to be executed in minutes, instead of days. The entire cash flow becomes transparent, legal, and traceable, unlocking global business expansion opportunities for Vietnamese enterprises.

Embracing the New Era of Payments

Stablecoin and CBDC are not opposing forces. They are two inseparable pieces in the future of digital payments.

For Vietnam, a nation integrating strongly with the world, the key is to build a solid "bridge" to connect these two worlds. The government and the State Bank are showing clear initiative on this journey—from legal frameworks and technology to operational pilots.

For businesses, the question is no longer "Stablecoin or CBDC?" but rather, "Which FinTech partner has the capability, technology, and legal standing to help us operate smoothly on both?"

The future of payments is closer than ever. Are you ready to embrace this new era and optimize your global cash flow?
