USDC Extends Its Lead in Stablecoin Payments

Circle’s USDC has strengthened its position in the stablecoin market, taking a dominant share of adjusted transaction volume during the first half of 2026. The latest onchain data tracked by Visa shows that USDC accounted for about 70% of adjusted stablecoin transaction volume over the period, while Tether’s USDT represented roughly 25%. That gap marks a significant shift in a market long associated with USDT’s early dominance and deep liquidity across crypto trading venues.

The change is notable because stablecoins have evolved beyond their initial role as trading collateral on digital asset exchanges. Fiat-pegged tokens are increasingly being used for payments, treasury movement, settlement flows and institutional transaction infrastructure. As the market matures, adjusted transaction volume is becoming a closely watched indicator because it attempts to filter out activity that does not represent real economic use, including bot activity, exchange transfers and other blockchain transactions that can inflate raw figures.

For FXCOINZ readers, the latest data points to a broader rotation in stablecoin utility. USDT remains a major player, but USDC’s share of adjusted activity suggests that regulated financial institutions and payment-focused users may be gravitating toward networks and issuers that are seen as aligned with compliance-heavy use cases. That does not eliminate USDT’s role in global crypto liquidity, but it does show that the volume race is no longer defined solely by exchange trading depth.

June Volume Sets a New High

Adjusted stablecoin transaction volume rose to a record $1.79 trillion in June 2026. That marked a 63% increase from May’s $1.1 trillion and a 125% increase from about $795 billion in June 2025. The scale of that month-on-month and year-on-year growth highlights how quickly stablecoins are becoming embedded in digital payment and settlement rails.

The first six months of 2026 produced $8.82 trillion in adjusted stablecoin transaction volume. That total already exceeded the $5.8 trillion recorded during all of 2024. It also stood $2 trillion below the record $10.8 trillion reported in 2025, underscoring how strong activity has been in the current year even before the second half is complete.

Market participants are watching whether this pace can continue. A single record month does not guarantee that activity will remain elevated, but the scale of the first-half total suggests that stablecoin usage is no longer confined to speculative trading cycles. Instead, transaction flows appear to be benefiting from a wider set of use cases, including corporate treasury activity, payment settlement and institutional transfers.

Banks Move Toward Established Stablecoin Networks

The growth in stablecoin volume is occurring as banks and other financial institutions expand their use of digital currencies for payments, settlement and treasury operations. Standard Chartered and BNY recently added services around Circle’s USDC rather than building their own stablecoin infrastructure. That choice points to an important development in institutional strategy: major firms may increasingly prefer to integrate with established fiat-pegged digital asset networks instead of launching standalone systems from scratch.

For financial institutions, stablecoins can offer a way to move value across blockchain networks while maintaining a link to traditional currency units. The appeal is especially clear in settlement workflows, where tokenized dollars can potentially reduce friction between counterparties, platforms and time zones. However, institutional adoption depends on confidence in the issuer, operational controls, redemption mechanisms and the broader regulatory environment.

USDC’s growing share of adjusted transaction volume suggests that some users view it as well positioned for these institutional requirements. Circle has built USDC around a dollar-pegged framework, and the token has become a common choice for payment applications, fintech integrations and blockchain-based settlement flows. The recent addition of USDC-related services by major banks reinforces the idea that established stablecoin networks are becoming part of mainstream financial infrastructure.

USDT’s Share Has Fallen From Earlier Dominance

Tether’s USDT remains one of the most widely recognized stablecoins in the digital asset market, but its share of adjusted transaction volume has declined sharply from earlier years. In 2020, USDT made up nearly 90% of adjusted stablecoin transaction volume, while USDC accounted for less than 10%. By 2022, USDC had risen to about 45% of adjusted transaction volume. In the first half of 2026, USDC accounted for about 70%, while USDT represented roughly 25%.

That evolution reflects the changing structure of stablecoin demand. USDT’s historical strength has been tied to crypto trading venues, cross-border liquidity and broad market familiarity. USDC’s rise, by contrast, appears increasingly linked to payment infrastructure, institutional integrations and use cases where transparency, bank connectivity and compliance considerations can be decisive factors.

Still, the stablecoin market is not a simple winner-take-all contest. Different users choose different tokens for different reasons, and liquidity can vary by blockchain, exchange venue and regional preference. USDT’s roughly 25% share of adjusted transaction volume remains substantial. The more important signal is that USDC has become the leading token by adjusted economic activity in the first half of 2026, based on Visa’s filtering methodology.

Why Adjusted Volume Matters

Blockchain activity can be difficult to interpret because raw transaction totals may include movement that does not represent genuine economic transfer. Exchange wallet reshuffling, automated behavior, internal transfers and other technical activity can make networks look busier than they are from a payments perspective. Adjusted volume attempts to clean up that picture by removing bot activity, exchange transfers and other blockchain transactions that do not reflect real economic activity.

This distinction matters for investors, policymakers and financial institutions. If stablecoin adoption is being evaluated as a payments and settlement trend, the quality of transaction volume is just as important as the headline number. A record adjusted volume reading carries more weight than a raw figure because it is designed to better capture meaningful value transfer across the ecosystem.

For crypto markets, the rise in adjusted stablecoin volume can indicate deeper liquidity, greater network utility and stronger demand for fiat-linked blockchain assets. For traditional finance, it can signal that digital settlement rails are becoming practical enough to support real business needs. For regulators, it may increase attention on reserve quality, issuer oversight and operational risk, particularly as stablecoins become more important to payment flows.

Market Implications for the Stablecoin Sector

The first-half data suggests that stablecoin competition is moving into a more mature phase. The sector is no longer defined only by which token has the largest presence on crypto exchanges. Instead, the market is increasingly shaped by institutional adoption, settlement use cases, bank partnerships and confidence in the infrastructure supporting each token.

USDC’s lead in adjusted transaction volume gives Circle a stronger position in the stablecoin utility narrative. If banks, payment companies and treasury teams continue to favor established stablecoin networks, USDC could remain a major beneficiary. At the same time, USDT’s continued share shows that it remains deeply embedded in digital asset liquidity and global crypto activity.

The record $1.79 trillion in adjusted monthly volume in June 2026 also places stablecoins firmly in the broader conversation about the future of money movement. Whether used by crypto-native firms or traditional financial institutions, fiat-pegged tokens are increasingly viewed as infrastructure rather than a niche trading tool. The next phase of growth will likely depend on reliability, regulation, liquidity and the ability of stablecoin networks to handle institutional-grade settlement demands.
