Stablecoin Distribution: Payments Are a Minor Part of the Ecosystem

A review of current stablecoin distribution by function finds payments constitute only a small part of the stablecoin ecosystem.

Research from the Kansas City Federal Reserve indicates that while stablecoin transaction volumes have grown substantially, the majority of activity remains confined to cryptocurrency trading, derivative collateral transfers, and protocol mechanics rather than real-world payments for goods and services. This assessment aligns with broader industry analyses showing that stablecoin usage in the real economy represents a minor fraction of total on-chain activity.

According to a Payments System Research Briefing released by the Kansas City Fed, stablecoins are increasingly used in bridging protocols that facilitate value transfer between different blockchain networks. However, these functions serve intermediation within crypto ecosystems rather than direct consumer or business payments. The briefing emphasizes that payments for actual goods and services remain a limited use case despite growth in stablecoin circulation.

Additional analysis from McKinsey & Company supports this view, noting that although stablecoin circulation has doubled over the past 18 months and transaction volumes reach into the trillions annually, blockchain data reveal that most activity is not tied to tangible economic transactions. Instead, significant portions are attributed to internal exchange settlements, trading activity, and routing through decentralized finance protocols.

A separate investigation by the Boston Consulting Group, cited in industry commentary, estimates that of more than $62 trillion in annual stablecoin transfers, only about $4.2 trillion corresponds to real economic activity — roughly 7% of the total. The firm’s behavior-based methodology further suggests that observable bilateral payments for goods and services in 2025 ranged between $350 billion and $550 billion, excluding off-chain usage such as stablecoin-linked card payments and internal exchange settlements.

Within this subset of real economy payments, business-to-business (B2B) transactions account for approximately 40% and are growing at an annual rate of 65%, while consumer-to-consumer (C2C) payments represent about 25% and are expanding at roughly 75% per year. These figures indicate emerging momentum in specific use cases, though overall adoption for everyday commerce remains limited.

The findings collectively suggest that while stablecoins are becoming more deeply integrated into cryptocurrency infrastructure, their role as a medium of exchange for everyday transactions has not yet materialized at scale. Regulators and financial institutions continue to monitor developments, particularly as stablecoin designs evolve and potential use cases in cross-border payments and programmable finance are explored.
