Stablecoins Moved $11.6 Trillion in 2025: What the Transaction Data Actually Shows

Stablecoins processed over $33 trillion in raw on-chain transaction volume during 2025. After applying filters to remove bot activity, flashloans, and exchange rebalancing, the adjusted figure lands near $11.6 trillion: a 91% increase over the prior year, according to data from the Visa Onchain Analytics Dashboard powered by Allium Labs. That adjusted number places stablecoin transfer volume in the same range as Visa's annual payments volume. But what does the data actually represent, and how much of it is real economic activity?

This article breaks down the $11.6 trillion figure: what gets filtered out, which chains carry the load, what types of activity drive volume, and how stablecoins compare to traditional payment rails once you apply consistent methodology.

Raw vs. Adjusted: Why the Gap Matters

The gap between $33 trillion in raw volume and $11.6 trillion in adjusted volume is not rounding error. It reflects a fundamental challenge in measuring blockchain economic activity: on-chain transactions mix genuine value transfer with automated infrastructure operations that have no parallel in traditional finance.

What Gets Filtered Out

The Visa and Allium methodology, co-developed with Castle Island Ventures and Artemis, uses over 3 million labeled addresses and probabilistic entity classification to separate organic transfers from inorganic activity. The filtering typically removes 70 to 90 percent of raw volume, depending on the chain and time period.

Categories stripped from the adjusted figure include:

• Flashloan cycles: single-transaction borrows repaid within the same block, accounting for 23 to 65 percent of volume on some chains
• DEX liquidity provisioning: automated deposits and withdrawals from liquidity pools that inflate volume without representing economic transfers
• MEV bot activity: maximal extractable value extraction through sandwich attacks, arbitrage, and backrunning
• Exchange treasury rebalancing: internal transfers between hot wallets, cold storage, and omnibus accounts
• Self-transfers: the same entity sending stablecoins to itself across addresses

The filtering problem is not unique to crypto: When comparing stablecoin volume to Visa or SWIFT, note that card networks only count consumer and merchant transactions. They do not include internal settlement flows, interbank transfers, or network overhead. The adjusted stablecoin figure attempts a similar scope, but the filtering remains imperfect and varies by provider.

Why Different Sources Report Different Numbers

The stablecoin volume figure depends heavily on who is counting and what they filter. Chainalysis reports approximately $28 trillion in "real economic volume" using less aggressive filtering. A January 2026 BCG and Allium white paper uses a broader transaction definition to arrive at $62 trillion. Meanwhile, when BCG narrowed the lens to real-economy payments between distinct parties for goods and services, the figure dropped to $350 to $550 billion.

The difference between $62 trillion and $350 billion is not fraud: it reflects different answers to the question "what counts as a payment?" The broader figures include legitimate DeFi operations, trading settlement, and treasury management that represent real economic value but are not comparable to a Visa card swipe.

Chain-by-Chain Distribution

Stablecoin volume does not distribute evenly across blockchains. Network choice reflects different use cases, fee structures, and user demographics.

Tron dominates adjusted transfer volume despite holding only about 30 percent of stablecoin supply. This asymmetry reflects Tron's role as the preferred network for cross-border transfers and peer-to-peer dollar-denominated payments in emerging markets, where low fees matter more than DeFi composability.

Ethereum commands the largest share of stablecoin supply (over $174 billion including L2s) but generates proportionally less adjusted volume. Much of Ethereum's raw volume comes from DeFi infrastructure: flashloans, liquidity provision, and MEV activity that the adjustment methodology filters out. A Talos and CoinMetrics analysis found that 65 percent of USDC volume on Ethereum consisted of flashloans, while USDT on Tron showed roughly 80 percent "residual" volume: peer-to-peer transfers, payments, and remittances that survive filtering.

Solana set a monthly stablecoin volume record of $650 billion in February 2026, briefly surpassing both Ethereum and Tron. The chain's low-latency architecture and sub-cent transaction fees make it competitive for high-frequency payment applications.

What Drives $11.6 Trillion in Volume

Decomposing the adjusted figure reveals several distinct categories of economic activity. None of them map cleanly onto consumer payments.

DeFi and Trading Settlement

The largest share of adjusted volume comes from DeFi protocol interactions and centralized exchange flows. Stablecoins serve as the base pair for most crypto trading: they account for approximately 40 percent of total cryptocurrency trading volume despite representing only 7 percent of crypto market capitalization. Every spot trade, perpetual futures settlement, and stablecoin swap generates adjusted transfer volume even when the adjustment methodology removes obvious automated activity.

Treasury and Corporate Operations

Standard Chartered estimated that corporates settled $2.4 trillion in B2B stablecoin payments during 2025. The BCG white paper found that 60 percent of real-world stablecoin payment volume is business-to-business, representing approximately $240 billion of the $400 billion midpoint estimate for real-economy payments. These include supplier payments, intercompany transfers, and trade finance settlement.

Cross-Border Remittances and P2P

Survey data from Castle Island Ventures and Brevan Howard across emerging markets found that 39 percent of stablecoin users cite cross-border remittances as a use case. Dollar access and savings ranked even higher at 47 percent. This aligns with Tron's dominance in adjusted volume: USDT on Tron is the de facto remittance rail in corridors across Sub-Saharan Africa, Southeast Asia, and Latin America.

On-Ramp and Off-Ramp Flows

Every fiat-to-crypto conversion and crypto-to-fiat exit generates stablecoin volume. As the stablecoin market cap grew from $205 billion to $300 billion during 2025, minting and redemption activity alone contributed meaningfully. The continued supply expansion shows that new capital keeps entering the stablecoin system.

Stablecoins vs. Traditional Payment Networks

The headline comparison: stablecoins versus Visa. But this comparison requires careful framing, because the networks serve fundamentally different functions.

On raw volume, stablecoins surpassed the combined total of Visa and Mastercard ($23.7 trillion) by roughly 39 percent. On adjusted volume, they sit close to Visa's payments volume but have not clearly exceeded it. On real-economy payments, stablecoins represent less than 4 percent of Visa's total.

The comparison trap: Visa processes consumer purchases at checkout. SWIFT routes interbank settlement messages. Stablecoins do both, plus DeFi settlement, plus treasury operations, plus remittances, in a single undifferentiated data stream. Comparing any single stablecoin figure to any single traditional network figure without specifying methodology produces misleading headlines in both directions.

The more meaningful metric may be growth rate rather than absolute volume. Adjusted stablecoin volume grew 91 percent year-over-year in 2025, with a 133 percent compound annual growth rate since 2023 according to Chainalysis. No traditional payment rail is growing at anything close to that pace.

Velocity: How Fast Each Stablecoin Dollar Moves

Money velocity: the rate at which each unit of currency changes hands: tells a different story than raw volume. A $200 billion stablecoin supply generating $11.6 trillion in adjusted annual volume implies each dollar turned over roughly 50 to 60 times during the year. But velocity varies dramatically by stablecoin and methodology.

USDT's 166x annual turnover reflects its role as the primary trading and remittance medium. USDC at 56x turns over less frequently but grew its supply base 78 percent during the year, suggesting expanding use cases rather than pure trading velocity. USDS (the Sky/Maker rebranding of DAI) barely turns over at all because most of its supply sits locked as collateral.

Standard Chartered found that overall stablecoin turnover ran at approximately 6x per month in 2025, roughly double the rate from two years prior. The bank flagged this acceleration as potentially reducing future demand for new stablecoin issuance: if each dollar works harder, fewer new dollars need to be minted to support the same level of economic activity. By mid-2026, the stablecoin market experienced its first supply contraction in four years while volumes continued growing, illustrating exactly this dynamic.

The 91% Growth Trajectory

The year-over-year growth in adjusted stablecoin volume tells a story of accelerating adoption. Monthly adjusted volume roughly doubled during 2025, rising from approximately $340 billion in December 2023 to $714 billion in December 2024, then continuing upward through 2025.

Several factors drove the acceleration:

• Stablecoin supply expanded from $205 billion to $300 billion, providing more liquidity for all use cases
• Monthly active stablecoin wallets grew 53 percent during the year, indicating new user adoption rather than existing users transacting more
• Monthly transaction counts rose from 755 million in January to 1.55 billion by December 2025, doubling in twelve months
• The GENIUS Act signed into law in July 2025 provided the first comprehensive US stablecoin regulatory framework, and the Federal Reserve noted a 50 percent increase in Ethereum stablecoin transaction volumes following its passage

The Chainalysis-reported 133 percent compound annual growth rate since 2023 outpaces every comparable financial metric. For context, global card payment volume grows at roughly 8 to 10 percent annually, and ACH transfers grow at about 6 percent.

The Skeptics: How Much Volume Is Real Commerce?

Critics argue that headline stablecoin volume numbers wildly overstate genuine economic activity. They have a point, and the data supports significant nuance.

BCG's Tiered Analysis

The most rigorous skeptical assessment comes from the January 2026 BCG and Allium white paper. It applied progressively stricter filters to arrive at a tiered view of what stablecoins actually do:

1. $62 trillion in total stablecoin transfers (broadest definition)
2. $4.2 trillion in estimated actual payments after removing non-economic activity
3. $350 to $550 billion in real-economy payments between distinct parties for goods and services

Despite the absolute growth in real-economy payments (up roughly 60 percent year-over-year), BCG noted that stablecoins' share of global payment flows remained at approximately 1 percent, unchanged from 2023 to 2024. The paper explicitly warned against comparing raw stablecoin volume to Visa or Mastercard.

The Plumbing Argument

A Talos and CoinMetrics analysis broke down volume by activity type on individual chains and found infrastructure operations dominate:

• USDC on Base: 69% DEX liquidity provision, 23% flashloans
• USDC on Ethereum: 65% flashloans, 2% CEX flows
• USDT on Ethereum: 46% flashloans, 9% CEX flows
• USDT on Tron: 19% CEX flows, ~80% residual (P2P, payments, remittances)

Their conclusion: "stablecoin transfer volume today is largely driven by the plumbing of crypto markets" rather than consumer payments. This does not mean the volume is fake. DeFi settlement, arbitrage, and market making are legitimate economic functions. But they are not analogous to someone buying coffee with a Visa card.

Where the Critics Overreach

Dismissing stablecoin volume as purely speculative ignores several realities. The $350 to $550 billion in confirmed real-economy payments grew 60 percent year-over-year and already exceeds PayPal's early growth trajectory. B2B stablecoin settlement reached $2.4 trillion, a figure that reflects genuine commercial activity between businesses. And the Castle Island survey data shows that in emerging markets, dollar savings and goods purchases rank as the top stablecoin use cases alongside trading.

The more honest framing: stablecoins in 2025 are a settlement infrastructure used primarily by crypto markets, with a fast-growing tail of commercial payment activity. The commercial tail is what matters for the next phase of adoption.

Supply Growth and the Velocity Question

Understanding the relationship between stablecoin supply and transfer volume reveals where the market is heading.

Stablecoin market capitalization grew from $205 billion to $300 billion during 2025, a 46 percent increase. But adjusted transfer volume grew 91 percent over the same period. This means velocity: the ratio of volume to supply: is accelerating. Each stablecoin dollar is being used more frequently for transactions.

USDT maintains the dominant market position at $186 billion (58 percent of total supply), but USDC grew its supply base 78 percent year-over-year, driven partly by regulatory clarity and Circle's positioning around the GENIUS Act. The competitive dynamics between the two largest stablecoins continue to shape the market.

The Federal Reserve's April 2026 analysis noted that USDT reserves cover approximately 1.04x coins in circulation, but higher-quality reserves (Treasuries, repo, bank deposits) cover only 0.74x. USDC maintains full 1.0x backing with high-quality reserves. These reserve composition differences become increasingly relevant as volume and systemic importance grow.

What the Volume Data Means for Infrastructure

Whether stablecoin adjusted transfer volume is $11.6 trillion or $28 trillion, the infrastructure implications are the same: settlement systems need to handle high-velocity, global, 24/7 atomic settlement at a scale that is already comparable to major traditional networks and growing at double-digit multiples annually.

Traditional card networks process payments at approximately 65,000 transactions per second at peak. Stablecoins on Ethereum L1 currently manage roughly 15 to 30 transactions per second, with L2s and alternative chains providing additional throughput. The throughput gap is narrowing as multi-chain infrastructure matures, but it highlights why payment-optimized layers matter.

This is where Bitcoin-native settlement infrastructure becomes relevant. Spark, built as a Bitcoin Layer 2 with instant settlement and native stablecoin support, is designed for exactly this type of high-velocity value transfer. Stablecoins like USDB on Spark can settle without the gas fee volatility and throughput constraints that affect Ethereum-based stablecoins during peak demand. As stablecoin transaction volume continues its trajectory toward and beyond card-network levels, settlement layers that combine low cost, high throughput, and self-custody will capture a growing share of the flow.

Builders looking to integrate stablecoin payment infrastructure can explore Spark's developer documentation and SDK. For a live example of a Spark-powered wallet handling stablecoin transfers, see General Bread.

Key Takeaways

The $11.6 trillion adjusted figure is neither a mirage nor a direct analogue to Visa's payment volume. It represents a mix of trading settlement, treasury operations, cross-border remittances, and growing commercial payments flowing through a new class of global payment infrastructure.

• Raw stablecoin volume ($33T) surpassed Visa and Mastercard combined, but 70 to 90 percent is automated infrastructure activity
• Adjusted volume (~$11.6T) is comparable to Visa, growing at 91 percent year-over-year versus single-digit growth for card networks
• Real-economy payments ($350-550B) are a small but fast-growing segment at 60 percent annual growth
• Tron dominates adjusted volume through emerging-market remittances; Ethereum dominates supply
• Velocity is accelerating: each stablecoin dollar works harder each year, potentially reducing the need for proportional supply growth
• Regulatory clarity from the GENIUS Act measurably increased on-chain activity, suggesting the commercial tail will grow as legal frameworks mature

The question is no longer whether stablecoin volume is real. It is how fast the commercial payment share will grow, and which settlement layers can handle the velocity when it does.
