"The USA, Singapore, Hong Kong, Japan, and the UK are not just the world's financial hubs they are the origin points of the stablecoin B2B payments revolution." Artemis Research, 2025

United States: The Largest Enterprise Stablecoin Sender

US businesses are the world's largest initiators of stablecoin B2B payments, driven by the scale of US international trade and the rapid adoption of USDC as a regulated dollar instrument. US enterprises paying suppliers in Asia, Latin America, and Europe are increasingly routing payments through USDC rather than SWIFT wires. The GENIUS Act's advancing regulatory clarity is accelerating this trend further, with major US corporates now running formal stablecoin payment pilots.

Singapore and Hong Kong: The APAC Stablecoin Hubs

Singapore, regulated by MAS, is the compliant gateway for Southeast Asian trade corridors the hub through which Singapore-headquartered multinationals pay manufacturers in China, Vietnam, Malaysia, and Indonesia. Hong Kong serves as the primary gateway for Greater China trade finance, with its unique RMB access and deep financial infrastructure. Both cities have well-developed digital asset custody and OTC infrastructure, making them natural nodes in the global stablecoin payment network.

Japan and the United Kingdom: Rising Enterprise Adopters

Japan's FSA has explicitly recognized stablecoins as a payment instrument. The UK's Financial Conduct Authority has issued guidance enabling regulated stablecoin custody. In both markets, large enterprises are beginning to use stablecoins for cross-border supplier payments and treasury management. The combination of regulatory clarity, sophisticated finance infrastructure, and high trade volumes puts Japan and the UK firmly in the top 5.
