"Stablecoin usage is rising faster than expected as new use cases emerge." — Standard Chartered Research Note, June 2026
Adjusted stablecoin transaction volume hit $8.82 trillion in the first half of 2026, according to Visa's Allium-powered on-chain analytics dashboard. June alone set a monthly record at $1.79 trillion — up 63% from May and 125% year-over-year. Circle's USDC accounted for 70% of that adjusted volume despite holding only 24% of total stablecoin market capitalization. Tether's USDT, which commands 59% of supply at $184.7 billion in circulation, processed roughly 25% of adjusted volume.
The divergence between supply dominance (USDT) and velocity dominance (USDC) represents a structural shift in how the two largest dollar-denominated stablecoins are used. USDC is becoming the transactional layer — payments, DeFi settlement, AI-agent transactions — while USDT functions increasingly as a store-of-value instrument in emerging markets. The annualized velocity of stablecoins reached 49.7x in mid-2026 according to DWF Labs, compared to M1 money velocity of 1.65x, suggesting that a small fraction of circulating supply is doing most of the economic work.
The numbers, per Visa Onchain Analytics (which uses Allium Labs data filtered for bot activity, exchange-internal transfers, and other non-economic noise):
| Month | Adjusted Volume | MoM Change | |-------|----------------|------------| | January 2026 | $1.18T | — | | February 2026 | $1.78T | +51% | | March 2026 | $1.42T | -20% | | April 2026 | $1.35T | -5% | | May 2026 | $1.10T | -19% | | June 2026 | $1.79T | +63% | | H1 Total | $8.82T | — |
For context: full-year 2024 adjusted volume was $5.8 trillion. Full-year 2025 was $10.8 trillion. H1 2026 alone has already reached 82% of the 2025 full-year figure, putting the market on pace for approximately $17-18 trillion annualized — a 57-67% year-over-year increase.
Total stablecoin market capitalization stood at $313 billion as of June 30, 2026, up 23% year-over-year from approximately $255 billion in June 2025 and up 93% from $161 billion in June 2024.
The market structure split is clear in the data:
By Market Cap (Supply):
By Adjusted Transaction Volume (H1 2026):
This means USDC turns over its supply approximately 83.6 times annualized, while USDT turns over roughly 24 times. In 2020, USDT accounted for nearly 90% of adjusted stablecoin volume and USDC less than 10%. By 2022, USDC had reached 45%. The current 70% share represents a complete inversion of the historic relationship.
The divergence maps directly to use-case segmentation:
USDC's volume drivers: DeFi protocol settlement, institutional payments, corporate treasury operations, AI-agent micropayments, and Coinbase ecosystem activity. Circle's compliance-first positioning and U.S. regulatory clarity make it the default rail for regulated entities.
USDT's supply drivers: Savings vehicle in dollarization-seeking emerging markets, peer-to-peer remittances (particularly in Latin America, Sub-Saharan Africa, and Southeast Asia), and exchange collateral. USDT's lower velocity reflects holders using it as a dollar-proxy savings account rather than a transactional medium.
June 2026 adjusted stablecoin volume by network:
| Network | Volume | Share | |---------|--------|-------| | Base (Coinbase L2) | $565B | 31.5% | | Ethereum | $562B | 31.4% | | Tron | $320B | 17.9% | | Solana | ~$200B | ~11.2% | | Others | ~$143B | ~8.0% |
Base overtaking Ethereum mainnet for the first time in June 2026 marks a significant infrastructure shift. Coinbase's L2 handled $565 billion — nearly identical to Ethereum's $562 billion — at a fraction of the gas cost. The implication: high-frequency stablecoin settlement is migrating to low-cost execution environments.
Earlier in 2026, Solana briefly led all networks in weekly adjusted stablecoin transfer volume (32.6% share in April according to one data set), though its ranking fluctuates monthly. Tron maintains consistent 18-20% share, primarily from USDT-denominated peer-to-peer transfers in developing markets.
By supply (as opposed to volume), the distribution differs markedly: Ethereum holds $154 billion (49%), Tron holds $90 billion (29%), Solana $15 billion, BNB Chain $14 billion, and Base $4.9 billion. Base's $4.9 billion supply generating $565 billion in monthly volume implies extreme velocity — over 115x monthly turnover — suggesting heavy automated/institutional usage rather than retail savings.
Stablecoin velocity provides the clearest window into economic utility. Key metrics:
The 49.7x aggregate velocity figure means that $313 billion in stablecoin supply supports roughly $15.5 trillion in annualized adjusted transaction volume. According to the European Central Bank, approximately 88% of stablecoin transactions remain tied to crypto trading rather than consumer or B2B payments. However, this ratio is shifting: B2B stablecoin payments surged from under $100 million monthly in early 2023 to over $6 billion monthly by mid-2025 — a 60x increase in 30 months.
The velocity data creates a counterintuitive dynamic for stablecoin issuers. If velocity continues rising, the market may not need proportionally more supply to support higher volumes. This compresses the traditional business model of stablecoin issuance — earning yield on reserves — because fewer reserves are needed per dollar of economic throughput.
Several institutional developments are concentrating volume in USDC:
Banking integration: Standard Chartered and Bank of New York Mellon (BNY) have expanded USDC-based services for clients, providing digital-dollar settlement and treasury management tools. The GENIUS Act's federal framework gives these institutions regulatory certainty to build on USDC rails.
Circle's public-company status: Circle priced its NYSE IPO at $31 per share in June 2025, giving it a $6.8 billion initial valuation. The stock has since appreciated significantly. Public-company transparency requirements — including SEC reporting — provide institutional buyers additional confidence versus privately-held stablecoin issuers.
Visa's direct engagement: Visa settled $4.5 billion annualized in stablecoins by January 2026, integrating USDC into core settlement operations. Mastercard acquired stablecoin infrastructure firm BVNK for $1.8 billion, signaling that card networks view stablecoin rails as complementary rather than competitive.
Cross-border enterprise payments: 71% of Latin American firms surveyed use stablecoins for cross-border payments. Nigeria processed an estimated $26 billion in stablecoin transaction volume in 2024, with USDC volume specifically jumping 412% year-over-year in 2025.
The regulatory environment has shifted from ambiguity to structured framework:
GENIUS Act (signed July 18, 2025): Establishes federal requirements for "permitted payment stablecoin issuers" including mandatory 1:1 reserve backing with high-quality liquid assets, monthly attestation requirements, and a path for nonbank issuers to obtain limited federal bank charters.
OCC Implementation (March 2026): The Office of the Comptroller of the Currency published proposed regulations for national banks and nonbank entities issuing stablecoins under the GENIUS Act framework. The OCC conditionally granted national trust bank charters to Circle, Paxos, and three other nonbank firms in December 2025.
AML/Sanctions Layer (April 2026): FinCEN and OFAC issued joint proposed rules requiring permitted payment stablecoin issuers to meet full BSA/AML and sanctions compliance obligations, treating them as financial institutions.
Tether's response: Tether announced engagement of an unnamed Big Four accounting firm for a comprehensive financial statement audit (not merely an attestation) on March 24, 2026. As of reporting, the audit remains incomplete. USDT's reserves are approximately 80% U.S. Treasuries, with the remainder in overnight repo, cash, ~$8 billion in gold, ~$7 billion in Bitcoin, and secured loans, per BDO Italia's quarterly attestations.
The regulatory asymmetry — USDC operating under a U.S. federal banking framework while USDT operates from El Salvador with attestation-only transparency — may be contributing to institutional volume favoring USDC. However, this same asymmetry may reinforce USDT's position in jurisdictions where U.S. regulatory compliance is irrelevant or undesirable.
The stablecoin market in H1 2026 no longer resembles its 2020 structure. What was once a monolithic USDT-dominated market has bifurcated along regulatory, geographic, and use-case lines. USDC's volume dominance reflects institutional preference for compliance clarity. USDT's supply dominance reflects demand for dollar-denominated savings in markets with limited banking access.
The $8.82 trillion in H1 adjusted volume represents real economic infrastructure — still predominantly crypto-native but increasingly penetrating B2B payments, remittances, and settlement. The key question for H2 2026 is whether velocity gains continue compressing the relationship between supply growth and volume growth, or whether new use cases (AI-agent payments, payroll, invoicing) require proportional supply expansion.
The data suggests the stablecoin market has crossed from experimental phase to infrastructure phase. The economics now resemble traditional payments networks more than crypto trading tools — albeit with 30x the velocity and without the intermediary extraction layers.
