KRW Stablecoin Regulatory Clash: BOK's Controversial 'Broadcasting Act' Precedent vs. US White House CEA's Bank Drain Refutation

Introduction

In April 2026, as the global competition for virtual asset regulatory supremacy intensifies, the stablecoin policies of South Korea and the United States are demonstrating a stark divergence. The Bank of Korea (BOK) has sparked intense controversy by demanding that traditional banks must own a mandatory majority stake (50% + 1 share) in any KRW stablecoin issuer, inexplicably citing the 'Broadcasting Act' as a legal precedent. Conversely, the US White House Council of Economic Advisers (CEA) released an empirical data-driven report directly refuting the traditional banking sector's fears of deposit flight, effectively siding with the digital asset industry. This comprehensive report analyzes the contrasting regulatory approaches between the two nations and provides actionable guidance for investors and industry stakeholders.

Legal and Regulatory Background

South Korean financial authorities and the BOK have consistently maintained a highly conservative approach to mitigate potential capital flight and anti-money laundering (AML) risks associated with KRW stablecoins. Recently, in a document submitted to the National Assembly, the BOK doubled down on its position that KRW stablecoin issuance must be controlled by a bank-led consortium with a minimum "50% + 1 share" ownership. Astonishingly, the BOK justified this aggressive corporate governance intervention by citing Article 8 of the Broadcasting Act and Article 18 of the Newspaper Act—laws originally designed to limit corporate ownership in public media.

In contrast, the US regulatory environment has already advanced toward a sophisticated, data-backed framework. The "GENIUS Act," enacted in July 2025, established a foundational federal regulatory structure for stablecoins. The act mandates a 1:1 reserve of high-quality liquid assets and introduced the Stablecoin Certification Review Committee (SCRC) to handle multi-agency approvals. Currently, the US House of Representatives is debating the "CLARITY Act," which addresses whether secondary yield-generation channels should be banned, sparking a fierce lobbying war between the banking and crypto sectors.

Core Analysis: Regulatory Galapagosization vs. Data-Driven Reality

The BOK's attempt to apply media monopoly laws to stablecoin regulation has faced scathing criticism from academia and the digital asset industry, who label it a severe "logical leap". The Broadcasting Act is fundamentally a regulatory "ceiling" (ownership limit) intended to prevent monopolistic control over public opinion. Applying this to high-tech financial infrastructure to enforce a regulatory "floor" (mandatory forced control by banks) entirely misconstrues the purpose and subjects of the legislation. Political figures, including Representative Min Byung-duk of the Democratic Party, have warned that such bank monopolies will stifle innovation and deepen Korea's subordination to USD-backed stablecoins.

Unlike Korea's fear-driven policy, recent US actions are anchored in empirical analysis. Published on April 8, 2026, the White House CEA report titled "Effect of Banning Stablecoin Interest on Bank Lending" systematically dismantled the traditional banking sector's narrative. The Independent Community Bankers of America (ICBA) previously claimed that allowing stablecoin yields could drain up to $1.3 trillion in deposits. However, the CEA's simulation models revealed that completely banning stablecoin interest would only increase traditional bank lending by a negligible $2.1 billion—a mere 0.02% of total lending.

Furthermore, the CEA data highlighted that 76% of this minimal loan increase would flow to mega-banks, leaving community banks with virtually no benefit. The White House officially concluded that banning yields does almost nothing to protect bank lending; instead, it solely results in depriving consumers of the competitive yields associated with stablecoin holdings.

Practical Guide and Tax Considerations

Investors and virtual asset service providers (VASPs) in Korea must take proactive steps to navigate this turbulent regulatory landscape.

First, the integration bill of the Digital Asset Basic Act currently under discussion in the National Assembly is moving toward a total ban on KRW stablecoin interest payments. As non-financial incentives like discounts and reward points are also likely to be restricted, domestic projects planning DeFi models based on KRW stablecoins must completely overhaul their revenue architectures.

Second, firms preparing to issue stablecoins must monitor the potential amendment of the "15% Rule" under the Banking Act. Financial authorities are considering revising banking supervision regulations to allow banks to own more than 15% of a stablecoin subsidiary. Consequently, fintech and blockchain companies should prioritize strategic partnerships or Joint Ventures (JVs) with commercial banks rather than pursuing independent issuance.

Third, significant caution is required regarding tax filings. While stablecoins themselves generally do not generate capital gains due to their fiat-pegged value, yield or airdrop rewards earned by staking USD stablecoins on overseas exchanges or DeFi protocols are classified as virtual asset income. These earnings are subject to a 22% separate taxation rate (including local income tax) in South Korea. Taxpayers must rigorously document their overseas yield histories in preparation for the comprehensive income tax filing period in May.

Outlook and Implications

The future of KRW stablecoin regulation stands at a critical crossroads. If the BOK's "50% + 1 share" mandate is enforced, the astronomical compliance costs and the naturally conservative decision-making structure of banks will erect insurmountable barriers to entry. This risks accelerating the "Galapagosization" of the Korean digital economy, leaving it vulnerable to being overtaken by globally dominant USD stablecoins like Tether (USDT) and Circle (USDC) that offer superior transaction speeds and efficiency.

Conversely, bolstered by the SCRC operations under the GENIUS Act and the empirical backing of the White House CEA report, the US is poised to foster a stablecoin ecosystem that maximizes consumer utility. It is highly probable that the crypto industry's stance will be heavily reflected in the final version of the pending CLARITY Act, subsequently cementing itself as the global standard.

Conclusion

The BOK's attempt to govern the KRW stablecoin ecosystem using the outdated yardstick of the Broadcasting Act represents a grave misstep that runs counter to global financial innovation. As proven by the US White House CEA report, regulators must move beyond hypothetical bank-run paranoia and adopt precise, data-driven risk management frameworks. Korean crypto investors and industry professionals must remain vigilant during this regulatory transition, prioritizing banking partnerships and ensuring strict compliance with overseas virtual asset tax reporting.
