One dollar, two worlds: How stablecoin adoption differs across the globe

Stablecoin adoption is bifurcating globally, with developed markets like the U.S. leveraging them as regulated, institutional-grade payment instruments following the GENIUS Act (July 2025), which mandates full backing but restricts retail yield-sharing to protect traditional banking. In contrast, emerging markets utilize stablecoins, predominantly USDT, as critical lifelines against inflation, currency devaluation, and high remittance costs, prioritizing stability and affordability, though corporate interest in yield is emerging. The sector, currently valued at $280 billion and projected to reach $2 trillion by 2028, sees 80% of its volume outside the U.S., reflecting these varied regional needs and regulatory landscapes, which necessitates adaptable issuer strategies despite inherent risks like counterparty exposure and lack of transparency.

Analysis

The global stablecoin market, which has reached a $280 billion valuation and is projected to hit $2 trillion by 2028, is experiencing a significant bifurcation in adoption and use cases. In developed markets, particularly the U.S., the 2025 GENIUS Act has established a regulatory framework mandating that stablecoins be fully backed by short-term assets like T-bills. This regulation enhances trust for institutional use but prohibits issuers from sharing interest revenue with retail holders, a move that protects traditional bank deposits from flight but limits retail appeal and, according to Tether's CEO, creates a financially challenging "race to the bottom" for issuers. Consequently, the U.S. market is dominated by institutionally-focused stablecoins like USDC. In stark contrast, emerging markets in the Global South utilize stablecoins, predominantly USDT, as essential tools for hedging against inflation, currency devaluation, and circumventing high remittance fees, which can exceed 12% in some regions. Here, utility and stability trump yield. Data from payment processor BitPay corroborates this trend, showing stablecoins constitute 40% of its payment volume in 2025, with USDT accounting for 61% of that volume, overtaking USDC. While 80% of stablecoin volume occurs outside the U.S., a new trend is emerging: corporate entities in developing nations are now seeking yield-enhanced instruments, signaling a potential future convergence of market needs. This dual-track evolution necessitates that issuers adopt flexible strategies tailored to either the regulated, institutional U.S. model or the high-growth, utility-driven model of the developing world, while navigating risks such as unregulated counterparties and potential competition from state-controlled CBDCs.

Key Decisions for Investors

• Given the clear bifurcation in stablecoin usage, investors should differentiate strategies, focusing on institutionally-integrated issuers like Circle (USDC) for the regulated U.S. market and those with dominant networks in high-growth emerging markets, such as Tether (USDT).
• The regulatory ban on retail yield-sharing in the U.S. pressures issuer profitability, so investment in the space should favor companies with strong institutional client bases or those positioned to capture the emerging corporate demand for yield products in the Global South.
• The explosive growth in transaction volume, particularly on cost-effective networks, indicates that a key investment vector is the underlying blockchain infrastructure; therefore, consider exposure to dominant L1s and L2s like Ethereum, Polygon, and Arbitrum, while monitoring the increasing market share of low-cost alternatives like Solana and Tron.
• Monitor the shift in payment preferences on platforms like BitPay, where USDT has overtaken USDC, as this provides a real-time indicator of relative adoption and market dominance, which can inform positioning in specific stablecoin-related assets or their underlying networks.
