Stablecoins: The Emerging Backbone of the Financial System

Stablecoins are rapidly transitioning from their initial role as transactional tools to a core infrastructure within the global financial system. As regulatory clarity advances and tokenization of real-world assets (RWA) accelerates, financial institutions worldwide are embracing stablecoins across various sectors, including asset management, payments, lending, and even AI-driven payment networks. Experts predict that stablecoins will fundamentally reshape financial systems, ushering in a new era of innovation and accessibility.

Stablecoins and Regulatory Evolution

At the Seoul Blockchain Conference on October 22, held at the Lotte World Tower Sky31 Convention Center, Taekyung Kim, partner at McKinsey & Company, highlighted the transformative journey of stablecoins. “In the past, stablecoins primarily served as intermediaries for digital asset trading. Now, with regulatory frameworks in place, compliant stablecoins are becoming central players in the financial ecosystem.”

A key driver of this transformation is regulatory clarity, which has catalyzed the rapid tokenization of RWAs. Tokenization involves converting tangible assets like real estate, equities, and loans into blockchain-based digital tokens, enabling fractional ownership and broader accessibility. This trend is restructuring the global financial value chain, positioning stablecoins as a critical enabler of tokenized economies.

Institutional Adoption of RWA Tokenization

Prominent financial institutions are leading the charge in tokenizing tangible assets. JPMorgan, for instance, is developing tokenized asset management systems using its proprietary blockchain network, revolutionizing how traditional assets are managed. Similarly, Robinhood is exploring ways to tokenize privately traded equities, positioning itself to reshape traditional securities business models.

Regional regulatory approaches play a crucial role, with countries like Japan, Singapore, Hong Kong, and Europe adopting diverse strategies toward stablecoin integration. Kim emphasized that these variations are driving innovative use cases, from democratizing investment access to tokenizing high-value but traditionally exclusive assets like private loans and real estate.

South Korea: Poised for Stablecoin Leadership

Experts assert South Korea’s high adoption rates of digital assets make it uniquely positioned to become a global leader in stablecoin integration. Gyu Taein, associate partner at McKinsey & Company, emphasized the importance of taking advantage of global trends. “Stablecoins have evolved beyond simple payment tools. They are now laying the foundation for deposit tokenization, digital asset banks, and AI-based payment networks. South Korea stands at an advantage due to its digital asset infrastructure.”

South Korea’s potential lies in proactively leveraging these advancements to develop new, stablecoin-powered use cases, aligning itself with international developments and accelerating innovation within the financial sector.

Three Key Directions for Stablecoins

Stablecoins are set to take three major directions in the years ahead, according to Taein.

1. Deposit Tokenization as the Future:
   Regulatory restrictions preventing issuers and banks from paying interest on reserves are encouraging innovation in deposit tokenization. Unlike traditional stablecoins, which require holding investor funds in isolated accounts, deposit tokens directly convert existing bank deposits into blockchain-based tokens, ensuring compliance with regulations.

Projects like Japan’s DCJPY demonstrate this trend, allowing banks to tokenize customer deposits for seamless payments. Similarly, JPMorgan is piloting deposit tokens for efficient corporate fund transfers on a large scale. This approach bridges fiat currency and digital assets while protecting funds under established safety nets like deposit insurance.

2. Emergence of Stablecoin Intermediaries:
   As hundreds of stablecoin variants come to market, intermediaries facilitating conversion and settlement will become indispensable. Taein explained, “Merchants and consumers cannot accept all stablecoin types simultaneously. Intermediaries will simplify transactions and settlements, ensuring widespread access and usability.”

3. Autonomous AI Agents and Financial Automation:
   Stablecoins offer unparalleled opportunities to power AI-driven economic automation. Taein foresees an era where autonomous AI agents use stablecoins to conduct payments and engage in market activities independently. “Just as autonomous vehicles operate without direct human control, similar agents could participate in digital economies powered by stablecoins,” Taein stated.

Major corporations, including Visa and Google, are already pioneering stablecoin-enabled infrastructure to support such autonomous financial processes, signaling the dawn of non-human economic agents equipped with blockchain technologies.

Stablecoins at the Crossroads of Finance and Technology

The growing proliferation of stablecoins within traditional finance and advanced technologies marks a paradigm shift. Their role in bridging fiat money with blockchain ecosystems goes beyond payment solutions to encompass democratized access to complex financial instruments like tokenized real estate and loans. Their integration into AI systems could redefine economic automation and create futuristic markets driven by non-human entities.

As financial institutions and corporations embrace stablecoin-powered business models, stablecoins are emerging as the backbone of an innovative global financial architecture. With ongoing regulatory developments and cutting-edge applications, these digital assets are poised to unlock unprecedented opportunities for industries, investors, and consumers alike.
