USDC activity has surged, but the amount of stablecoin that payment firms actually need to hold may depend less on headline transaction volume and more on how efficiently those firms manage liquidity.
Circle reported $13.9 trillion in USDC onchain transfers during the third quarter, up 49% from a year earlier.
Average USDC circulation, however, increased by only 8% to $73.3 billion.
That gap highlights an important question for Circle’s Arc blockchain: if businesses can move far more money while keeping relatively small working balances, how much new USDC demand will payments actually create?
Arc uses USDC for both settlement and gas
Circle launched Arc publicly on September 16 with USDC as the network’s gas currency.
That means businesses can use the same asset to pay transaction fees and settle dollar-denominated transfers.
For payment providers, this can simplify treasury management because network costs and payment balances are measured in the same currency.
However, using USDC for gas does not automatically mean firms must hold large balances.
A company that replenishes its gas wallet frequently may need only a small amount of USDC available at any one time.
Another provider that prefunds several days of activity may keep a much larger balance.
Payment volume does not equal stablecoin demand
A payment company can process very large transaction volumes without holding an equally large amount of USDC.
Consider a firm that sends $100,000 in supplier payments each business day.
If it receives enough USDC each morning to cover the day’s payments, it may need only around one day of working capital plus a safety buffer.
If the same company must prefund five days of payments, it could need roughly $500,000 before adding any operational reserve.
The total payment flow is similar.
The amount of USDC sitting on the company’s balance sheet is very different.
Timing is the key variable
The biggest factor is the gap between incoming money and outgoing obligations.
If customer funds arrive before a payment needs to be made, a provider can reuse those funds quickly.
If the business must pay recipients before customer money arrives, it needs more working capital.
That is where recurring payments can create stablecoin demand.
A company may keep USDC onchain because it needs to be ready to settle transfers quickly.
At the same time, faster settlement can reduce the size of that buffer by making funds reusable sooner.
Both effects can happen at once.
USDC transfers rose much faster than supply
Circle’s third-quarter numbers show how quickly transaction activity has expanded.
USDC onchain transfer volume reached approximately $13.9 trillion during the quarter.
Average circulating supply stood at around $73.3 billion.
Dividing transfer volume by average circulation produces a rough turnover ratio of about 190 times.
A year earlier, the comparable ratio was closer to 137 times based on the reported growth rates.
This does not mean every USDC coin changed hands 190 times.
The same tokens can move repeatedly through exchanges, liquidity pools, payment systems, and settlement accounts while other balances remain untouched.
The calculation simply shows that activity grew much faster than average supply.
Not every USDC transfer is a payment
Gross onchain transfer data includes far more than purchases or supplier payments.
USDC can move because of:
- Exchange activity
- DeFi trading
- Liquidity management
- Cross-chain transfers
- Internal treasury movements
- Payments
- Settlement between financial institutions
That makes it difficult to use total transfer value as a direct measure of payment demand.
A better analysis would identify which addresses belong to payment providers and then measure how much USDC they actually retain between settlements.
Circle Payments Network is a separate measure
Circle also reported that Circle Payments Network reached approximately $41.3 billion in annualized payment volume.
That figure should not be added directly to the $13.9 trillion quarterly transfer total.
The two numbers measure different things.
The $13.9 trillion figure covers broad USDC onchain activity across networks.
The $41.3 billion figure represents the annualized pace of activity through Circle Payments Network.
Annualized volume is a run rate based on recent activity, not a record of an entire year already completed.
Arc was live for only part of the quarter
Arc launched publicly on September 16.
That means the third-quarter company-wide data includes only a few weeks of Arc activity.
Most of the reported USDC transfers occurred across the wider stablecoin ecosystem.
A clearer picture of Arc’s contribution will require a full quarter of operating data.
Analysts will need to compare Arc-specific transaction activity with balances held by known payment providers and liquidity firms.
What would show real payment-driven USDC demand?
Several metrics would provide a clearer picture than gross transfer value.
One is the average USDC balance held by payment providers.
Another is net issuance.
If Arc attracts existing USDC from Ethereum or another network, local Arc balances may increase without total USDC supply growing.
But if businesses need additional stablecoins that ultimately require new issuance, that would represent stronger evidence of new demand.
Recurring settlement activity is also important.
A provider that uses Arc repeatedly over several months provides stronger evidence of sustainable demand than a one-time transfer.
Moving USDC to Arc is not the same as creating new USDC
Circle’s cross-chain infrastructure allows USDC to move between blockchain networks.
In a burn-and-mint transfer, USDC is destroyed on the source chain and recreated on the destination chain.
Arc may therefore show an increase in local USDC supply even though the global supply has not changed.
For example, if $10 million of USDC moves from Ethereum to Arc, Arc gains $10 million while Ethereum loses roughly the same amount.
That is a relocation of existing supply, not necessarily $10 million of new stablecoin demand.
Net issuance matters more than gross minting
Circle reported large amounts of both USDC issuance and redemptions during the quarter.
Gross minting can be very high even when total circulating supply changes only modestly.
If $10 billion is minted and nearly the same amount is redeemed, the net supply increase can remain small.
For stablecoin demand, the more important measure is whether issuance consistently exceeds redemptions over time.
That shows whether more digital dollars are actually remaining in circulation.
Gas spending creates its own USDC demand
Arc’s decision to use USDC for gas gives the stablecoin another role.
Every network transaction requires some USDC to cover fees.
For businesses, this can make costs easier to understand because fees are denominated in dollars rather than a volatile native token.
However, gas spending and gas balances should still be treated separately.
A provider might spend $1,000 on transaction fees during a month while maintaining only a small gas wallet because it replenishes the account regularly.
Another business might prefund months of expected network fees and keep a much larger standing balance.
Payment firms can separate gas and settlement balances
Using USDC for both purposes does not mean companies must manage everything from one wallet.
A payment company could maintain a small account dedicated to network fees.
A separate treasury account could hold the much larger amount needed to settle customer payments.
Platforms can also sponsor gas on behalf of users.
In that arrangement, customers may never directly see the gas cost even though the provider still needs USDC to pay it.
StableFX adds another layer of demand
Circle has also introduced StableFX on Arc.
StableFX allows institutions to exchange stablecoins or tokenized currencies using a request-for-quote model.
This creates another reason for market makers to hold USDC.
A liquidity provider may need balances in multiple currencies so it can respond to customer trades.
Those balances can be reused repeatedly.
But if trading flows become heavily one-sided, the provider may need additional inventory or need to rebalance between markets.
Liquidity providers may hold USDC even when customers do not
A customer does not necessarily need to maintain a long-term USDC balance for the stablecoin to be important to a payment route.
A market maker may hold USDC to provide quotes.
A payment company may hold it to fund customer settlements.
A treasury may use it for supplier payments.
Several firms can interact in the same payment chain.
This makes it important not to count each transfer as if it represented a completely new dollar of demand.
Local payouts can reduce visible stablecoin balances
Circle’s planned acquisition of Tazapay illustrates another issue.
Recipients often want money in their local bank account rather than in USDC.
A payment provider might receive USDC, convert it almost immediately into local currency, and send the recipient a bank payment.
In that case, USDC is important to the settlement process but may remain on the provider’s balance sheet only briefly.
Another provider might keep large USDC reserves available because it expects to make additional payments later.
Both businesses can generate substantial stablecoin payment activity while creating very different levels of persistent USDC demand.
Tazapay could expand Circle’s payout reach
Circle says Tazapay provides payout connectivity across more than 100 markets.
The acquisition is expected to close in 2027, subject to regulatory approval.
If completed, the deal could expand Circle’s ability to connect stablecoin settlement with local banking systems.
That could increase payment activity on Arc or within Circle’s broader infrastructure.
But the impact on USDC demand will still depend on how providers manage their working balances.
More payment routes do not necessarily mean equally large increases in circulating supply.
Daily snapshots may miss liquidity needs
Looking at a provider’s wallet balance at one moment can also be misleading.
A company may build up a large USDC balance during the afternoon before processing a batch of payments.
It might then move the remaining funds back to a treasury account before midnight.
A midnight balance snapshot could therefore understate how much USDC the company needed during the day.
The reverse can also happen.
A snapshot taken just before a large payout could make the provider appear to hold more USDC than it normally does.
Analysts need repeated observations across similar time periods.
Circle reported $865 million in quarterly revenue and reserve income
Circle reported approximately $865 million in third-quarter revenue and reserve income, up 17%.
Reserve income accounted for about $658 million.
That figure declined 8% from a year earlier even though average USDC circulation increased.
The reason was that lower returns on reserve assets outweighed the benefit of having a larger average stablecoin supply.
This highlights another distinction.
Higher USDC adoption does not automatically translate into proportionally higher reserve income if interest rates on the backing assets fall.
Reserve income and payment activity measure different things
Circle earns reserve income from the assets backing outstanding stablecoins.
Payment volume measures how actively those stablecoins are being used.
The two can move in different directions.
USDC could circulate much faster without total supply increasing significantly.
Alternatively, payment firms could begin holding larger working balances, increasing supply even if transaction growth slows.
For investors evaluating Circle or Arc, these should be treated as separate indicators.
What would prove Arc is creating sustainable USDC demand?
The strongest evidence would come from several measures moving together.
Payment providers would maintain meaningful USDC balances on Arc across multiple settlement cycles.
The same firms would repeatedly process transactions over weeks or months.
Global USDC issuance would grow after accounting for redemptions.
Liquidity firms would maintain inventory in USDC for StableFX and other markets.
And Arc-specific activity would increase without simply reflecting tokens moved from another blockchain.
Together, those indicators would show that Arc is creating a persistent need for digital dollars rather than only increasing turnover.
What investors should watch
The most useful indicators include:
- Payment provider USDC balances
- Repeat settlement activity
- Global USDC issuance and redemptions
- USDC moved onto Arc from other chains
- Arc gas spending
- StableFX liquidity balances
- Tazapay rollout and payment volumes
- Provider balances held between settlement cycles
These measures can help distinguish genuine inventory demand from simple movement of existing tokens.
Arc’s real test is how much USDC stays in the system
Circle’s numbers show that USDC usage is expanding rapidly.
Third-quarter onchain transfers increased 49%, while average circulation grew only 8%.
That suggests each dollar of USDC is supporting significantly more activity than before.
Arc could strengthen demand if payment firms, market makers, and merchants need larger stablecoin balances to keep their operations running.
But faster settlement could also allow businesses to recycle the same funds more efficiently and operate with smaller buffers.
That is the central question.
The success of Arc as a payment network should not be measured only by how many dollars move through it.
For USDC demand, the more important number is how many digital dollars businesses need to keep available after the transfers are complete.
