Circle Payments Network Joins Thunes as Stablecoin Rails Expand Into Cross-Border Transfers
Thunes, a cross-border payments network, has joined Circle‘s Circle Payments Network, extending stablecoin-based transfer infrastructure into new markets. The integration was listed in PR Newswire’s financial services wire as of May 17.
The announcement positions Circle Payments Network as an active layer in institutional cross-border settlement rather than a consumer-facing product.
What the Thunes Integration Means
Thunes describes itself as a “smart superhighway” for global money movement, connecting payment networks, banks, and mobile wallets across more than 130 countries. Its integration into Circle Payments Network means that transfers routed through Thunes can settle in USDC (USDC), Circle’s dollar-denominated stablecoin, rather than requiring conversion through traditional correspondent banking chains.
The practical effect is a reduction in settlement time and cost for corridors where Thunes is already active.
Emerging market corridors, particularly in Southeast Asia and sub-Saharan Africa, have historically carried the highest fees in cross-border payments because of the number of correspondent banking intermediaries involved. A stablecoin settlement layer reduces the number of hops required to move value from sender to recipient.
The integration was signed against a backdrop of growing Southeast Asian institutional interest in digital asset infrastructure.
A separate PR Newswire release from the same period listed senior Thai and Indonesian officials alongside Circle, Tether (USDT), and Bitkub leadership at a regional blockchain summit, reflecting active government engagement with stablecoin payment systems across the region.

What Circle and USDC Are
Circle is a U.S.-based financial technology company and the issuer of USDC, a stablecoin, a cryptocurrency designed to maintain a fixed value against the U.S. dollar by holding equivalent reserves in cash and short-term Treasury instruments. Circle reports those reserves monthly through an independent attestation process.
USDC is the second-largest stablecoin by market cap globally.
Circle launched the token in 2018 in partnership with Coinbase through the Center Consortium, a governance body that was later dissolved when Circle took full ownership of USDC in 2023. The stablecoin is currently issued natively on more than a dozen blockchains, including Ethereum, Solana (SOL), and Arbitrum (ARB), giving it broad reach across decentralized finance ecosystems.
Circle Payments Network is a separate product from USDC itself.
It is a business-to-business settlement infrastructure layer that allows financial institutions and payment companies to use USDC as the settlement asset in their existing payment flows without requiring their end customers to interact with cryptocurrency directly.

Background
Circle has spent much of 2025 and 2026 expanding Circle Payments Network beyond its initial roster of pilot partners. The effort accelerated after Circle filed for a U.S. initial public offering in early 2025, giving the company incentive to demonstrate revenue-generating B2B infrastructure rather than relying solely on interest income from USDC reserves.
Stablecoin payment networks have attracted significant partnership activity across the sector.
Competing issuers, including Tether and new entrants backed by major banks, have announced similar infrastructure deals as the global payments industry evaluates whether stablecoins can reliably replace correspondent banking for high-volume corridors. The U.S.
Senate’s continued work on stablecoin legislation in 2026 has given institutional partners more confidence that the regulatory framework for these products will stabilize.
Thunes had previously raised funding from investors including GIC, Singapore’s sovereign wealth fund, and Helios Investment Partners, giving it credibility as an infrastructure partner in regulated markets.

What to Watch
The Thunes integration is one data point in a broader test of whether Circle Payments Network can build enough institutional volume to justify its positioning as a neutral settlement layer. The key metric is transaction throughput, specifically how many dollars per day settle through CPN versus through traditional correspondent banking on the same corridors.
Circle’s IPO trajectory will also shape how aggressively the company pursues additional partnerships.
A successful public listing would give Circle the capital and public profile to negotiate larger integrations with Tier-1 banks. Regulatory clarity on stablecoin issuance in the European Union and the United States, both expected in the second half of 2026, will determine whether institutional partners can expand their stablecoin settlement activity without compliance risk.
