The Growth of Stablecoins and Their Status in the Future Financial System Stablecoins, which have grown rapidly in recent years, are establishing themselves as a core pillar of the global financial system, extending beyond the cryptocurrency market. Unlike volatile assets such as Bitcoin, stablecoins are pegged to fiat currencies like the US dollar or Euro, offering relative stability. Due to these characteristics, stablecoins are gaining attention not merely as digital currencies but as a new financial layer capable of impacting the entire economy. According to a report by BCA Research, stablecoins are evolving from niche cryptocurrency tools into a macroeconomically significant financial layer that connects global payments with US dollar liquidity and the short-term Treasury market. This implies the potential to overcome the inefficiencies of existing international payment systems while also creating new payment frameworks. The report particularly emphasizes that by combining blockchain's inherent efficiency with value stability, stablecoins demonstrate strong utility across various sectors, marking the beginning of their institutional adoption. Although BCA analyzed that stablecoins still account for a relatively small share of global payments and financial assets despite their rapid expansion, it projected that continued growth, regulatory clarity, and institutional adoption will increase their economic influence over the next decade. In 2025, over 70% of jurisdictions reviewed the introduction of new stablecoin regulatory frameworks, and this momentum is accelerating further as 2026 progresses. This clearly demonstrates that stablecoins have emerged as a significant agenda item in global financial policy. Following the prospect that stablecoins can become a true medium of exchange on public blockchains due to their value stability, numerous regulatory authorities are recognizing the importance of tailored regulatory frameworks for stablecoins. One of the key advantages of stablecoins is their innovative role in cross-border payments. Currently, most international remittances rely on traditional financial networks, which incur high costs and take considerable time. Chris Colson of the Federal Reserve Bank of Atlanta emphasized that stablecoins can address these issues, stating that they improve payment efficiency and expand payment options beyond traditional bank deposits and cash. Specifically, he explained, "Stablecoins support more direct cross-border payments for consumers, provide liquidity management and automated cross-border commerce options for businesses, and offer financial institutions opportunities to expand innovative financial services." Particularly in trade-oriented countries like South Korea, such cross-border payment efficiency is expected to have a positive impact on overall economic activity. Regulation and Challenges: Finding a Balance However, the rapid growth of stablecoins has simultaneously brought about new regulatory challenges and macroeconomic hurdles. Key issues faced by regulators include ensuring the quality, transparency, and redeemability of reserves, clarifying regulatory oversight, and managing operational and cybersecurity risks. One of the biggest concerns is the transparency and redeemability of reserves for issued stablecoins. Central banks and regulatory bodies have warned of the potential for negative impacts on financial markets if stablecoin reserves are not adequately backed or are commingled with bank deposits. Furthermore, there is a risk that increased stablecoin usage could lead to the collapse of existing payment networks or accelerate bank deposit outflows. Moreover, new approaches and industry collaboration are required to effectively manage macroeconomic risks such as currency substitution, volatile capital flows, and payment fragmentation. These regulatory gaps and systemic risks are emerging as critical challenges that future financial policies must address. According to industry analysis, some argue that stablecoins' impact will be limited because the existing financial system still operates on a high level of trust. For instance, the globally recognized SWIFT network still holds a strong position as the standard system for cross-border payments. However, stablecoins are not merely a technological innovation; they are focused on enhancing customer satisfaction through new services that the existing system could not provide, such as real-time payments, lower fees, and 24/7 operation. This suggests that stablecoins are more likely to act as complementary assets in collaboration with the existing financial system rather than directly competing with it. The Korean Economy and the Future of Stablecoins According to expert analysis, the development of stablecoins is expected to particularly impact the Korean economy. South Korea, with its digitally savvy consumer base and high smartphone penetration, possesses an optimal environment for adopting such in
