WTO: Stablecoins Make Up 3% of Cross-Border Payments

The World Trade Organization released a research paper titled Stablecoins in International Trade in Geneva on Sept. 14, 2026, finding stablecoins represent roughly 3% of international payments. Juan Marchetti, director of the WTO’s trade in services and investment division, presented the report and argued regulatory fragmentation, rather than limits in settlement technology, constrains broader use.

The paper lists five trade finance frictions stablecoins could address: high costs, slow settlement, limited access, weak transparency and foreign exchange constraints.

The 3% figure measures stablecoins against total international payments, not headline on-chain volume. On-chain throughput runs into the tens of trillions of dollars a year, much of it trading, decentralized finance activity and arbitrage. The WTO cites an estimate that real-economy stablecoin payments total about $390 billion annually, roughly 1% of on-chain volume. Cross-border stablecoin use grew roughly 35-fold between 2020 and mid-2024.

The report references a Financial Stability Board review showing 11 of 28 surveyed jurisdictions had finalized stablecoin frameworks as of October 2025, about 39%. It notes that even where frameworks exist, key details remain unresolved. The EU’s Markets in Crypto-Assets regulation applied in June 2024 and the transitional window for existing providers closed on July 1, 2026. In the United States, the GENIUS Act was signed in July 2025 and takes effect Jan. 18, 2027. The U.S. Treasury issued a proposed rule on stablecoin issuance in August 2026 with a public comment period ending Oct. 19, 2026.

The WTO describes a practical compliance problem for operators: a cross-border stablecoin payment typically falls under at least two regulatory regimes, and reserve composition rules, licensing categories and redemption obligations do not align cleanly between major frameworks such as MiCA and the GENIUS Act or with rules in Singapore, Hong Kong, the UAE and Nigeria. Marchetti warned, ‘what remains unresolved is whether a payment that is compliant in one jurisdiction stays compliant when it crosses a border.’ Firms seeking multi-region coverage must absorb mismatches internally, raising compliance costs as the number of corridors served increases.

Business-to-business flows make up the largest portion of real-economy stablecoin activity and are most exposed to the regulatory patchwork described in the report. The WTO highlights developing economies as places that could see the largest reductions in fees and delays on remittance and trade corridors where correspondent banking is thin, while noting those markets often have less developed rulebooks.

The WTO identified near-term milestones to watch: the U.S. Treasury comment window on proposed GENIUS Act rules closes Oct. 19, 2026 and the GENIUS Act becomes effective Jan. 18, 2027. The next FSB review will show whether more jurisdictions have completed rulebooks beyond the current 39%. The WTO Public Forum will run Sept. 15–17, 2026 in Geneva, where trade policy makers will discuss services and digital payments.

The report states immediate priorities for market participants include building licensing footprints, ensuring corridor-level compliance and developing interoperable arrangements that keep payments lawful at both ends of a border.
