Stablecoins facilitated approximately $46 trillion in transfers over the last 12 months, according to a new report from a16z crypto. Additionally, crypto trading volume exceeded $80 trillion during the same period.
When measured against payment “flows,” stablecoins represent a low single-digit percentage of global settlement. They are beginning to match mainstream payment rails in scale for specific applications, such as cross-border transfers and 24/7 treasury operations.
The context of this comparison is important. With global payments valued at roughly $2 quadrillion in 2024, stablecoins account for approximately 2.3% of the world’s payment flows on a flow-to-flow basis.
This approach maintains a consistent denominator and avoids the common error of comparing a flow series against a money stock.
For those seeking a different perspective, dividing the $46 trillion flow by the U.S. M2 money stock of approximately $22.195 trillion (August 2025 reading) yields a raw ratio of nearly 207%. However, these series measure different metrics and should not be interpreted as a “share of dollars.”
According to data from FRED and McKinsey, the accurate conclusion is that stablecoins have entered the payments conversation in terms of flow.
In U.S. benchmarks, stablecoins remain smaller than wholesale wires and roughly half the size of the Automated Clearing House (ACH) system on an annualized basis.
The Federal Reserve’s Fedwire Funds Service processed approximately $1.133 quadrillion in 2024, while Nacha’s ACH value, annualized from third-quarter 2025 volumes, stands near $93 trillion.
These benchmarks illustrate where on-chain dollars currently fit and where growth could head if policy and distribution continue to expand.
| Rail / Metric | Value | Timebase | Source |
|---|---|---|---|
| Stablecoin settlement (TTM) | ~$46T | Trailing 12 months, 2025 | a16z crypto |
| ACH value (annualized) | ~$93T | Q3 2025 run-rate | Mastercard |
| Fedwire Funds value | ~$1.133Q | Full year 2024 | FRBservices |
| Global payments value | ~$2.0Q | Full year 2024 | McKinsey |
A stock-to-stock perspective helps assess the footprint of tokenized dollars within the monetary base.
With an average stablecoin float ranging between $250 billion and $300 billion over the past year, the tokenized portion represents slightly more than 1% of the M2 money stock.
This framing aligns with the view that stablecoins act as instant-settlement wrappers on money market-style reserves rather than deposits. This has implications for Treasury market infrastructure, as reserve composition favors short-dated bills. The key variables are the float size and its turnover rate.
Velocity indicates how frequently each on-chain dollar turns over.
Dividing the $46 trillion in trailing-twelve-month transfers by an average float of $250 billion to $300 billion results in an implied annualized turnover of approximately 150 to 185 times. This figure serves as a color metric rather than a welfare indicator, as internal hops, exchange wallets, and automated flows can inflate counts.
Adjusted transfer methodologies, such as the netting of internal movements used by a16z, can narrow the gap between raw and economic volume.
According to a16z crypto, combining raw and adjusted series provides a clearer method for tracking adoption across retail transfers, B2B corridors, and exchange settlement.
Policy is increasingly defining how and where these flows interact with the regulated sector. The U.S. GENIUS Act, signed into law in July, establishes a federal framework for reserves, licensing, and issuer disclosures that banks and payment processors can underwrite.
The legislation provides agencies with timelines for rulemaking and sets the baseline for supervised issuance, custody, and attestations. Issuer behavior is already shifting toward a compliance-focused approach.
Reserve composition brings the Treasury market into focus. Stablecoin issuers collectively hold over $150 billion in U.S. Treasury bills, positioning the sector among the larger marginal buyers at the front end.

If stablecoin float expands through new distribution channels, the resulting demand for T-bills becomes a mechanical function of growth and reserve policy rather than a discretionary trade. This connection is becoming increasingly relevant to rates desks and public-sector observers monitoring bill supply.
Distribution is the second key driver behind throughput numbers.
Card networks, processors, and enterprise wallets are beginning to integrate on-chain settlement into checkout flows, supplier payments, and remittance rails. Often, stablecoins are confined to the interbank leg while user interfaces remain familiar.
Multiple dollar stablecoins are now enabled across selected pilots and programs, expanding acceptance pathways without requiring changes in consumer behavior.
This template, combined with lower-fee base layers and faster block times, contributes more to throughput figures than pure speculative churn.
Stablecoin payment flow modeling
Forward scenarios through 2027 focus on three variables: policy cadence, distribution depth, and reserve carry.
A base path featuring normalized U.S. oversight and expanding fintech integrations projects a stablecoin float of roughly $450 billion to $650 billion and trailing-twelve-month transfers near $70 trillion to $90 trillion. This implies a 3% to 4.5% share of global payment value if the McKinsey denominator grows at its historical pace.
A higher-uptake path, including payroll, merchant settlement, and issuance by supervised U.S. banks, could push the float toward $800 billion to $1.2 trillion. This would result in $110 trillion to $150 trillion in annualized transfers and a 5% to 7% global share, alongside $300 billion to $500 billion in T-bill holdings if reserve policies remain bill-heavy.
A slower path, reflecting stricter filtering of non-economic transfers and delayed on-ramp rules, would keep the float in a $350 billion to $450 billion band with throughput near $50 trillion to $60 trillion, maintaining a global share closer to 2.5% to 3%.
These ranges are directional and should be evaluated using adjusted transfer series to account for noise from internal wallet moves.
Flow metrics include internal hops and automated strategies that do not always map directly to economic activity. Additionally, cross-source timebases vary, with global payments anchored in 2024 while the stablecoin tally is trailing and current.
Distinction between flow and stock, and pairing raw with adjusted series, prevents overstating adoption while still reflecting the scale of settlement clearing on public chains.
According to a16z crypto, the combination of adjusted volume and wallet cohorting offers a better gauge for new use cases.
Regulatory alignment is now influencing issuer roadmaps. Tether has outlined a U.S.-regulated USA₊ product to be issued under the new framework, with Anchorage Digital acting as the issuing entity.
What does this mean for Bitcoin and crypto?
For markets, a $46 trillion, ~2.3% share of global payment value running through “dollar tokens” indicates that the dollar leg of crypto is deepening and accelerating, which is bullish for BTC/ETH liquidity.
For Bitcoin, thicker stablecoin pools on exchanges and in market-maker inventories reduce fiat friction and tighten spreads. This tends to lift spot and perpetual contract volumes and improves price discovery during risk-on periods.
For Ethereum, stablecoins are a primary user of blockspace (increasingly on L2s). Higher payment throughput generally translates to more fee revenue, a higher propensity for burn under EIP-1559, and a clearer link from payments activity to ETH cash flows and supply dynamics.
If policy continues to widen distribution (banks, processors, enterprise wallets), stablecoin float and turnover could become a leading indicator for the next phase of BTC demand and a structural tailwind for ETH network economics. Additionally, on-chain dollars provide 24/7 liquidity during macro shocks, potentially dampening some volatility.
