Stablecoins now handle USD 226 billion in real B2B payments yearly. This article breaks down market size, USDT vs USDC, the IMF’s USD 300 billion finding, GENIUS Act rules, and where India, the US, and Europe stand on regulation.
Overview:
- Stablecoin payments remain small but are gaining ground in B2B, payroll, remittances, and treasury use.
- USDT and USDC dominate supply, while dollar-pegged tokens account for nearly the entire market.
- New rules in the US, Europe, and India will shape stablecoin adoption and cross-border payments.
Money still moves slowly across borders. A wire transfer can take days and pick up fees at every stop. Banks work on different hours and follow different rules. Businesses and workers feel that delay every week.
Stablecoins offer another route. These tokens track a national currency, mostly the U.S. dollar, and settle on a blockchain within minutes. Total supply stood at USD 302.8 billion on September 10, 2026.
An IMF study examines how U.S. stablecoin legislation affected the market value of listed payment companies. This article reviews the numbers, the real use cases, and the rules that will shape the next phase.
Market Size and Key Players
Supply has grown fast, though it has cooled lately. Five years ago, it sat under USD 10 billion. The market crossed USD 320 billion in April 2026 and has slipped 0.8% over the past 90 days.
Two issuers hold most of the supply. Tether’s USDT accounts for 60.57%, and USDC follows with USD 74.2 billion. USDC leads in activity, though. It processed USD 18.3 trillion in 2025, compared with USD 13.3 trillion for USDT. Nearly all supply, 99.4%, is pegged to the dollar. About 269 million on-chain addresses held a stablecoin balance by mid-2026.
Trackers count differently, so figures vary slightly by source. The table below pulls the key numbers together.
Business Payments Lead Real Usage
Headline volume can mislead. Analysts counted about USD 33 trillion in stablecoin transfers during 2025. Most of it was trading and movement between wallets and exchanges. McKinsey and Artemis found only USD 390 billion reflected real payments, which equals 0.02% of global flows.
Business transactions carry that total. B2B payments reached USD 226 billion, up 733% from the prior year. Supply chain payments, supplier settlements, and treasury management drive that growth. Payroll and remittances added USD 90 billion, while card spending reached USD 4.5 billion. Asia accounted for about 60% of volume.
Infrastructure firms tell the same story. Monthly volume rose from USD 5 billion in January 2024 to above USD 30 billion by early 2026, BVNK reported. Stripe’s purchase of Bridge and Mastercard’s partnership with BVNK show large firms building on these rails.
What the IMF Study Found
An IMF working paper, dated March 20, 2026, tracked stock prices around U.S. stablecoin legislation. The paper estimates the legislation cut the market value of listed payment firms by 18%, roughly USD 300 billion. The effect was slightly larger than earlier shocks such as the Durbin Amendment and the digital euro plan.
Cross-border specialists were most exposed. Firms with strong network effects or existing crypto services fared better. The authors add that engaging with the technology could help firms prosper.
This view matches Grayscale Research, which expects the biggest inroads in cross-border payments. In short, markets treat stablecoins as a serious competitor to established payment firms.
Regulation Sets the Pace
US Rules Under the GENIUS Act
President Trump signed the GENIUS Act on July 18, 2025. It requires full reserve backing with liquid assets. The law takes effect on the earlier of January 18, 2027, or 120 days after final rules. The Treasury issued a proposed rule in August 2026 that defines who needs a license. From July 18, 2028, providers may sell only tokens from licensed issuers.
Europe and MiCA
In Europe, the MiCA rules reached their hard enforcement deadline on July 1, 2026. Together with the US law, this gives issuers clearer rulebooks in two large markets.
India’s Cautious Approach
July 2026 reports show the RBI still leans toward prohibition and opposes foreign and rupee-pegged stablecoins. Its May 2026 payments report argued that stablecoins fail the core test of money. The bank prefers the digital rupee, which has over 8 million pilot users.
Its tone has softened slightly. The June 30 Financial Stability Report described US, EU, and UK rules as steps toward clearer boundaries. Demand is real, as India has nearly 39 million crypto investors.
Quick Points to Remember
- Real stablecoin payments equal just 0.02% of global volume today.
- B2B transfers drive most genuine usage, led by Asia.
- USDT and USDC control most supply, and nearly all tokens track the dollar.
- GENIUS Act licensing will decide which tokens reach US users.
- India’s stance may shift, though the digital rupee remains the RBI’s priority.
Final Thoughts
Stablecoins have moved from trading desks into invoices, payroll, and treasury work. Real usage remains small beside a payments market above USD 20 trillion. Growth rates are steep, though, and large firms are already building around them. The IMF’s findings suggest that stablecoin legislation has affected how markets value established payment companies.
The next two years will test this shift. US licensing rules will take hold, and other countries will set their own terms. India’s path remains uncertain. Readers should track licensing decisions and actual payment data instead of headline volumes. Stablecoins are an emerging payment option, although their share of global payment flows remains small.
