Stablecoins stay trading-led as research shows payments lag

Stablecoin payments share is under 1% of real-world payments

according to McKinsey & Company, annual real payment volumes using stablecoins are about US$390 billion, roughly 0.02% of global payments flows. That level places stablecoin settlement far below 1% of real-world payment activity.

The gap reflects a measurement reality: most recorded stablecoin transfers are not purchases or invoice settlements. They are on-chain movements that inflate raw volumes without corresponding commerce.

On-chain transactions vs real payments: trading drives most volume

According to TD Economics, crypto trading dominates stablecoin use, with about US$23 trillion in trading activity versus roughly US$4 trillion in payments, leaving payments near 6% of total activity. Cross-border flows via stablecoins remain negligible compared with overall cross-border volumes.

Hilary J. Allen, a law professor, cites analysts indicating that about 88% of 2024 stablecoin transaction value related to crypto trading, with only about 6% tied to payments. She also notes that just 1.9% of Americans used any crypto for payments in 2024.

Analysts use “on-chain, watered‑down” to describe high-frequency exchange transfers and protocol operations that pad volumes without generating economic settlement. “Legal real‑world payments have thus far been a very small use case for stablecoins,” said Hilary J. Allen in written evidence to a UK parliamentary committee.

Impact on B2B, cross-border stablecoin payments, and policy

Based on data from McKinsey, B2B stablecoin payments are estimated around US$226 billion annually, tiny relative to total B2B volumes, with even smaller shares in remittances and capital-markets settlement. The figures indicate niche traction rather than broad displacement of existing rails.

Policy perspectives emphasize business-case clarity over headline throughput. “For stablecoins to really serve as a means of retail payments, they must present both a compelling use case and a clear business case,” said Governor William (Brad) Waller of the Federal Reserve Board.

How experts define and measure stablecoin payments share

What counts as real payments vs on-chain or protocol transfers

Real payments are settlements for goods and services, remittances, and B2B invoices. On-chain transfers commonly include exchange internal movements, crypto-for-crypto trading, protocol-level operations, and bot-driven flows that do not settle commerce.

FAQ about stablecoin payments share

How do McKinsey and TD Economics estimate stablecoin payments compared to total global payments?

McKinsey estimates about US$390 billion, or ~0.02% of global flows. TD Economics finds payments near 6% of stablecoin activity, far below trading-dominated volumes.

What qualifies as a real payment versus an on-chain or trading transfer?

Real payments settle goods, services, remittances, or B2B invoices. On-chain transfers include trading, exchange shuffling, protocol operations, and bot-driven movements not tied to commerce.
