Circle's Singapore Hub and Stablecoin Payouts Infrastructure: Accelerating Institutional Adoption in Southeast Asia (2026)

US-based stablecoin issuer Circle Internet Financial has significantly expanded its footprint in Southeast Asia in 2026, transforming its Singapore hub into a critical node for global stablecoin-powered payment infrastructure. By securing local licensing, launching advanced programmatic API solutions, and establishing strategic partnerships with major regional cross-border networks, Circle is positioning its digital dollar (USDC) as a core transactional rail and middleware for the mainstream global economy.

Major Payment Institution (MPI) License and Payouts API Launch

Operating through its locally licensed entity, Circle Internet Singapore Pte Ltd—which holds a Major Payment Institution (MPI) license from the Monetary Authority of Singapore (MAS)—Circle announced a major product expansion in early 2026:

• Stablecoin Payouts API Expansion: Circle expanded access to its Payouts API to partners contracted with Circle Mint Singapore. This marks Circle's first Payouts API expansion outside its US-based entity (Circle Mint LLC).
• Automated Scaled Payouts: The launch allows Asia-based payment service providers (PSPs), fintechs, and enterprises to programmatically automate compliant, large-scale third-party payouts using USDC, reducing manual complexity and operational overhead.
• Regulatory Compliance: The Payouts API in Singapore is specifically designed to align with local Travel Rule requirements and MAS regulatory expectations, providing a fully compliant path for financial institutions to scale stablecoin-based payout use cases.

Strategic Partnership with Thunes

In April 2026, Circle solidified its integration with traditional financial systems by partnering with Singapore-based cross-border payments giant Thunes:

• Circle Payments Network Integration: Thunes joined the Circle Payments Network (CPN) Managed Payments, enabling its global customers to access stablecoin-powered settlement within their existing fiat-based workflows.
• Liquidity Optimization: By integrating USDC into Thunes' Direct Global Network (which spans more than 140 countries), banks, money transfer operators, and gig economy platforms can settle transactions in near real-time. This round-the-clock settlement significantly reduces the need for heavy pre-funding in local nostro accounts and eliminates dependence on traditional banking hours.

Rapid Growth and the "Economic OS" Vision

This regional expansion aligns with Circle's broader corporate momentum. In its Q4 and full-year 2025 earnings (reported in February 2026), Circle revealed:

• USDC Supply Expansion: USDC in circulation reached $75.3 billion (up 72% year-over-year).
• Volume Surge: Quarterly on-chain transaction volume skyrocketed 247% to $11.9 trillion.
• The Internet Financial System: Circle is actively building out its "Economic OS for the internet," which includes the Circle Payments Network (CPN) for real-time global settlement (with 55 financial institutions enrolled and 74 more under review), StableFX for continuous foreign exchange, and Arc (an enterprise blockchain).

Strategic Takeaway for US Expansion Teams

Circle's developments in Singapore demonstrate that stablecoins are moving beyond speculative crypto assets to become enterprise-grade transaction rails. For US fintechs expanding into Southeast Asia, Circle's compliant Singapore infrastructure provides a reliable, low-cost mechanism for cross-border B2B settlement, treasury management, and payroll automation, circumventing the high fees (often exceeding 6%) and slow speeds of legacy correspondent banking.
