USDC Overtakes USDT in Transaction Volumes as Stablecoin Regulation Debate Intensifies

Key Highlights

• USDC has surpassed USDT in adjusted stablecoin transaction volume for the first time since 2019
• Analysts estimate USDC processed roughly $2.2 trillion in adjusted volume in 2026 compared with USDT’s $1.3 trillion
• USDC now reportedly accounts for around 64% of adjusted stablecoin transaction activity
• Despite the shift in volume, USDT remains the largest stablecoin by market capitalization
• Growing regulatory pressure is increasingly benefiting compliance-focused stablecoins like USDC
• Governments and central banks worldwide are accelerating stablecoin regulatory frameworks
• Institutional adoption continues driving demand for regulated dollar-backed digital assets

The stablecoin market is undergoing a major structural shift after Circle’s USDC overtook Tether’s USDT in adjusted transaction volume for the first time in years, signaling changing dynamics across digital payments and institutional crypto infrastructure.

According to estimates from Mizuho analysts, USDC has processed approximately $2.2 trillion in adjusted transaction volume so far in 2026, compared with roughly $1.3 trillion for USDT. That gives USDC an estimated 64% share of combined adjusted stablecoin flows, marking a significant reversal from the period between 2019 and 2025 when USDT consistently dominated transaction activity.

The “adjusted” transaction metric removes exchange reshuffling, wash trading, and automated internal transfers in order to better reflect real economic activity such as payments, settlements, peer-to-peer transfers, and institutional transactions. Analysts say this provides a clearer picture of actual stablecoin usage across financial infrastructure.

Despite the volume shift, Tether’s USDT still remains the dominant stablecoin by total market capitalization, with circulating supply significantly larger than USDC’s. USDT continues maintaining strong liquidity dominance across global exchanges and emerging markets, particularly in regions where access to traditional dollar banking infrastructure is more limited.

Analysts increasingly attribute USDC’s rise to growing institutional preference for compliance-focused stablecoins amid intensifying global regulation. Circle has generally positioned USDC as a transparency-oriented and regulator-friendly product, which appears to be resonating with payment firms, fintech platforms, and institutional settlement systems.

The shift is occurring as regulators worldwide accelerate efforts to formalize stablecoin oversight. Governments in the United States, Europe, and the United Kingdom are developing new frameworks governing reserve requirements, licensing standards, redemption rules, and consumer protections tied to fiat-backed digital assets.

Central banks and policymakers are increasingly treating stablecoins as part of core financial infrastructure rather than simply crypto trading tools. Stablecoin transaction volumes have expanded dramatically in recent years, with industry estimates suggesting the sector processed tens of trillions of dollars in annual transfer activity during 2025 alone.

Institutional adoption is also reshaping the competitive landscape. USDC has gained traction within payment systems, tokenized asset settlement, enterprise treasury operations, and regulated financial applications where compliance standards are often prioritized over pure liquidity dominance.

At the same time, Tether continues maintaining strong advantages in global trading markets and crypto-native liquidity infrastructure. Many analysts believe USDT is unlikely to lose overall market cap leadership in the near term, particularly due to its entrenched role across international exchanges and emerging-market payment ecosystems.

The competition between USDC and USDT increasingly reflects a broader divide emerging within the stablecoin sector: one model centered around regulatory integration and institutional finance, and another focused on global liquidity access and crypto-native market dominance.
