How Stablecoins Became a Tool for Global Payments

Key Concepts

• Stablecoins: Cryptocurrencies pegged to a stable asset (usually the US Dollar) designed to minimize price volatility.
• Remittance: The transfer of money by a foreign worker to their home country.
• Blockchain Rails: The underlying digital infrastructure used to move stablecoins across borders.
• Stablecoin Sandwich: A process where fiat currency is converted to stablecoins for transmission and converted back to local currency at the destination, often invisible to the end-user.
• Bips (Basis Points): A unit of measure in finance; 100 basis points equals 1%.
• Regulatory Frameworks: Legal structures (like those in Singapore and Japan) requiring 100% liquid reserves for stablecoin issuers.

1. The Evolution of Global Payments

Stablecoins are positioned as a transformative force in the global financial system. While currently a small segment of the total payment volume, projections from Bloomberg Intelligence suggest that stablecoin-based transfers could reach $56 trillion by 2030.

• Current Scale: Matt Higginson (McKinsey) notes that while media reports often cite "trillions" in volume, roughly 99% of that is crypto-trading activity. Real-world payment volume is estimated at approximately $390 billion annually, or $1–2 billion per day.
• Growth: Despite the modest current volume, the market is doubling year-over-year, with stablecoins in circulation rising from $150 billion to $300 billion recently.

2. Real-World Application: Remittances

The primary utility of stablecoins currently lies in cross-border remittances, particularly for migrant workers.

• Case Study (Philippines): With 2 million Filipinos working abroad sending $35 billion annually (7% of GDP), the cost of traditional banking is a major friction point.
• Cost Efficiency: Traditional remittance costs have dropped from 8% (a decade ago) to 2–4%. Stablecoins can reduce these costs to 20–50 basis points (0.2%–0.5%).
• The "Stablecoin Sandwich" Methodology:
  1. Origin: A user deposits USD into a platform (e.g., Remitly).
  2. Conversion: The platform converts USD to stablecoins.
  3. Transmission: Stablecoins move instantly across the blockchain.
  4. Destination: A local partner (e.g., Coins.ph) converts stablecoins into local currency (pesos).
  5. User Experience: The blockchain layer is invisible; the user only interacts with fiat at both ends.

3. Regulatory Perspectives and Frameworks

Regulation is viewed as the "gatekeeper" for mass adoption.

• The Singapore/Japan Model: These regions were early adopters of frameworks requiring 100% liquid reserves to back issued stablecoins.
• Standardization: Sopnendu Mohanty (Monetary Authority of Singapore) argues that existing payment regulations (KYC, AML, and counter-terrorism financing) are sufficient for stablecoins, provided they are supplemented with technical requirements.
• US Regulatory Outlook: The upcoming "Genius Act" in the US is expected to provide the regulatory clarity needed for banks to integrate stablecoins into their infrastructure at scale.

4. Strategic Arguments: Banks vs. Crypto

• The "Speed vs. Risk" Trade-off: While stablecoins offer instant, low-cost transfers for small amounts (e.g., $200–$1,000), they are not necessarily ideal for large corporate transfers (e.g., $5 million), where "friction" and manual oversight are preferred to prevent errors.
• Bank Integration: Wei Zhou (CEO, Coins.ph) emphasizes that banks should not view stablecoins as a replacement, but as a tool for growth. Banks that embrace this technology are seeing significant competitive advantages, with some moving from mid-tier to top-tier status by becoming the primary banking partner for crypto exchanges.
• Trust and Adoption: For the average consumer, trust remains the primary barrier. Users prioritize convenience and safety, often preferring the "vault" security of traditional banks over the complexity of managing digital wallets.

5. Notable Quotes

• Wei Zhou: "When you're running $40 billion of remittance, for every 1% that you save, that's like $400 million that goes back into the people's pockets right away."
• Sopnendu Mohanty: "The single biggest unsolved challenge in the world of payment is the cross-border payments... in that particular use case, a stablecoin is a great product."
• Matt Higginson: "Building trust is expensive, doing compliance is expensive... once you put all that in place, it's a highly scalable business."

Synthesis and Conclusion

Stablecoins are transitioning from a niche crypto-trading tool to a legitimate financial rail for global remittances. The technology’s success depends on three pillars: regulatory clarity (to ensure safety and trust), infrastructure integration (allowing banks to act as the interface for non-tech-savvy users), and cost-efficiency (specifically for small-value, high-frequency cross-border payments). The future of the industry lies not in replacing the legacy banking system, but in becoming a highly efficient, regulated layer within it.
