US and South Korea Push for Unified Stablecoin Regulations Amid Market Challenges
PILLAR DIAGNOSTIC // WEEK 15
“Given regulatory prohibitions on interest-bearing digital liabilities and no signals of tiered CBDC yields, the risk posture for a remunerated CBDC is low. This non-remuneration stance may limit CBDC competitiveness versus private yield-bearing assets and slow uptake.”
Proposed action
Policymakers should publicly clarify the CBDC’s interest policy, explore a narrowly defined tiered yield framework in line with policy rates, and monitor private stablecoin yield offerings to address potential adoption shortfalls.
THE MECHANICS
What happened
USDC has increased its market share over USDT in Q1 2026, despite substantial inflows to USDT via TRON.
THE MACHINE
Sources & records
Yield-bearing stablecoins have increased significantly, contrasting with regulatory prohibitions on interest-bearing capabilities for stablecoins.
THE MAP
Context & constraints
The FDIC is advancing stablecoin regulations under the GENIUS Act while South Korea is independently proposing similar legislative measures.
THE MOOD
Framing & reaction
Structural tailwinds for Bitcoin are anticipated following halving events, while a retail CBDC is deemed essential for countering foreign digital currency dominance.
