Original Title: Inside Circle’s Stablecoin Economics
Compiled and Edited by: BitpushNews
Currently, Circle is still viewed as a reserve-income business, rather than a scaled software or payment fee platform. Its profit model remains tightly linked to stablecoin balances, short-term interest rates, and the share of reserve income retained after paying substantial distribution fees.
Fiscal Year 2025 clearly illustrates this point: reserve income accounted for $2.637 billion of the total revenue and reserve income of $2.747 billion, while other income contributed only $110 million. Therefore, the company's recent financial performance is still primarily driven by the average circulating supply of USDC, the realized reserve yield, and the economics of partner revenue-sharing agreements, particularly the agreement with Coinbase.
FY 2025 showed strong nominal revenue growth, with total revenue and reserve income increasing from $1.676 billion in FY 2024 to $2.747 billion. Reserve income grew from $1.661 billion to $2.637 billion, while other income increased from $15 million to $110 million. Despite this, Circle reported a net loss attributable to common shareholders of $70 million for FY 2025, with a significant increase in operating expenses, including $845 million in compensation costs.
The core debate for 2026 is not whether Circle is pursuing strategic expansion, but whether this expansion is financially substantive. The key variables remain:
Whether USDC balances continue to grow, how the reserve yield evolves in a low-interest-rate environment, whether distribution costs remain structurally heavy, and the pace at which emerging revenue streams—such as those related to CCTP, CPN, and USYC—expand relative to the reserve income base.
At this stage, Circle's strategic footprint is clearly expanding, but the core investment framework remains unchanged: it is still an interest-rate-sensitive, balance-sensitive financial infrastructure company whose profitability is dominated by reserve income, not diversified platform monetization.
Circle Overview
Circle is a financial technology company listed on the New York Stock Exchange (NYSE) under the ticker symbol CRCL. The company filed its FY 2025 10-K annual report for the year ended December 31, 2025, on March 9, 2026. Circle's FY 2025 balance sheet shows "stablecoin holder deposits" of $74.9 billion, highlighting that the company's economic core still lies in the scale of its reserve-backed stablecoins and their management, rather than a traditional pure-software model.
From an analytical perspective, Circle can be divided into four layers. First, it is a stablecoin issuer, primarily through USDC and EURC, with liabilities tied to outstanding stablecoins and segregated reserve assets held for users. Second, it is a reserve income business, monetizing reserve assets through interest and dividend income. Third, it is building a developer, payment, and infrastructure layer aimed at increasing the utility and transaction density of its stablecoins. Fourth, it is assembling a broader strategic stack around an "Internet Financial System," including Arc, the Circle Payment Network (CPN), and tokenized asset infrastructure. However, the disclosed performance shows that the current financial engine is still the reserve income model, not a scaled software or transaction fee business. Circle reported total revenue and reserve income of $2.747 billion for FY 2025, with reserve income contributing $2.6368 billion, leaving only a relatively small portion attributable to non-reserve activities.
This distinction is crucial for valuation. Circle's strategic narrative is clearly broadening, but the revenue structure does not yet support valuing the company primarily as a software platform rerating story. In Circle's earlier disclosures, "other products" accounted for only 1% of total revenue in 2024, although management separately indicated that other revenue accelerated significantly in 2025, with Q4 2025 other revenue at $37 million, a $34 million year-over-year increase. This supports a directionally positive platform narrative but has not yet replaced the centrality of reserve balances, reserve yields, and partner economics in shaping profitability.
Another strategic pillar is the regulatory structure. Circle disclosed that in December 2025 it received conditional approval from the U.S. Office of the Comptroller of the Currency (OCC) to establish a national trust bank called First National Digital Currency Bank, N.A. Management characterized this as a significant step to strengthen USDC infrastructure and potentially expand regulated custody and reserve management capabilities. Analytically, this may enhance perceived regulatory durability and institutional confidence in reserve governance but should not yet be viewed as a disclosed profit driver.
Business Model and Economics
Circle's business model is primarily driven by the interaction of two variables: outstanding stablecoins and the yield earned on reserve assets. The company explicitly defines reserve income as a function of reserve balances and reserve returns. In FY 2025, Circle reported reserve income of $2.6368 billion, up from $1.6611 billion in FY 2024. In contrast, other income totaled $109.8 million in FY 2025, compared to $15.2 million in FY 2024, with $84.8 million in subscription and service revenue representing the largest non-reserve component in FY 2025. This confirms that Circle's profitability remains extremely sensitive to interest rates and balance growth, even as auxiliary revenue streams have begun to expand from a relatively small base.
The reserve base is designed for conservative management. Circle disclosed that as of June 30, 2025, approximately 87% of USDC reserves were held in the Circle Reserve Fund, a government money market fund regulated under Rule 2a-7, managed by BlackRock, and custodied by BNY Mellon. The remainder was held as cash in accounts maintained for the benefit of USDC holders, primarily deposited at global systemically important banks. Circle also stated that its reserve management framework is designed to comply with relevant regulatory requirements, including NYDFS guidelines for USDC and MiCAR-related reserve requirements for EURC. This implies the reserve construction is optimized first for liquidity, principal protection, transparency, and regulatory compliance, not for yield-maximizing portfolio risk.
Circle's economics are also deeply influenced by distribution arrangements, most notably with Coinbase and other ecosystem partners. While reserve income is recorded on a gross basis, the company pays substantial downstream payments through distribution and transaction costs. Prior disclosures suggest these costs are linked to the generation of reserve income and platform balances, meaning a significant portion of gross reserve economic benefits is contractually shared rather than fully retained. This is visible in the cost structure: in FY 2025, Circle reported Revenue Less Distribution Costs (RLDC) of $1.083 billion on total revenue and reserve income of $2.747 billion, implying a large portion of gross monetization was paid out through the distribution layer before operating expenses.
This is critical for modeling. Circle is not a pure beneficiary of rising rates or increased USDC balances, as growth in gross reserve monetization does not translate 1:1 into retained profit. In Circle's prior sensitivity disclosure, a +100 basis point change from the 4.26% average reserve yield as of June 30, 2025, implied an estimated $618 million change in reserve income but also a $315 million change in distribution and transaction costs. This suggests a large portion of gross reserve yield is shared, with only the remainder flowing to RLDC before operating expenses. For institutional analysis, RLDC is therefore a more useful intermediate profitability measure than mere reserve income, though it remains inherently sensitive to rates and balances.
The reported earnings quality for FY 2025 was also significantly impacted by non-core and non-cash items. Circle disclosed a net loss from continuing operations of $70 million for FY 2025, despite reporting $582 million in Adjusted EBITDA, a gap partly stemming from anomalously large equity incentive expenses tied to IPO-related vesting conditions. In the FY 2025 earnings report, Circle stated that performance was significantly impacted by $424 million in equity incentive expense related to IPO vesting. In the filing, Circle further disclosed that $423.8 million in stock-based compensation expense was recognized because the commencement of trading on the NYSE made the related RSU performance conditions probable. This implies GAAP net income is not the best lens to assess underlying unit economics or profitability.
The most significant reason is Circle's arrangement with Coinbase, which remains one of the most notable and often underestimated aspects of its business model.
When USDC launched in 2018, Circle and Coinbase formed a joint consortium to govern the stablecoin. This structure was dissolved in 2023, with Circle assuming full control of issuance. However, Coinbase retained a highly attractive revenue-sharing arrangement.
Under this agreement, Coinbase receives 100% of the reserve income from USDC held on its own platform, plus 50% of the reserve income generated elsewhere. In 2024, $908 million of Circle's total distribution costs of $1.01 billion were paid to Coinbase. Effectively, this means that for every $1 Circle earns, about $0.54 is paid to a company that neither issues USDC nor manages its reserves. By early 2025, Coinbase's share of total USDC supply held was 22%, up from 5% in 2022. As USDC concentration on Coinbase continues to rise, Circle's payment burden increases correspondingly.
The broader analytical conclusion is that Circle should currently be viewed as an interest-rate-sensitive financial infrastructure company built around a stablecoin-dominated reserve income engine, not a software platform whose economics are primarily driven by subscription or transaction revenue. Platform option value is becoming clearer, particularly through Arc, CPN, and the expansion of non-reserve revenue streams. However, Circle's disclosed FY 2025 revenue structure still supports a framework centered on reserve balances, reserve yields, and distribution sharing mechanisms. Until non-reserve revenue becomes a material portion of total revenue, the reserve income model will remain the primary driver of Circle's earnings sensitivity and the core of its valuation debate.
Deep Dive into USDC and EURC
The regulatory backdrop for Circle's flagship stablecoins improved substantially in 2025. In the U.S., the White House stated that President Donald Trump signed S. 1582, the GENIUS Act, into law on July 18, 2025, establishing a federal framework for payment stablecoins. Reuters similarly reported that the law requires issuers to back stablecoins with liquid assets like dollars and Treasury bills and to disclose reserve composition monthly. Circle's FY 2025 10-K described the GENIUS Act's expectations for reserve assets (including cash, deposits, short-term Treasuries, and repos or reverse repos) as broadly consistent with Circle's existing USDC reserve management practices. Analytically, this consistency reinforces Circle's regulation-first positioning, though the company's profitability remains more influenced by distribution agreements and market structure than by regulation alone.
USDC
Heading into 2026, USDC remains the core economic engine of Circle's model. Circle reported in its FY 2025 10-K that USDC in circulation stood at $75.266 billion as of December 31, 2025. Circle's USDC product page subsequently showed circulation at $79.2 billion as of March 16, 2026. On this basis, USDC circulation increased by approximately $3.9 billion, or about 5.2%, between year-end 2025 and mid-March. This is not an explosive step-change but does indicate continued net growth on top of an already strong 2025 base.
USDC Stablecoin Supply (Source: Allium)
Circle's own disclosed FY 2025 data points to a strong year of growth for USDC. In Q4 2025, the company reported USDC in circulation grew 72% year-over-year to $75.3 billion, while USDC on-chain transaction volume grew 247% year-over-year to $11.9 trillion. For the full year, Circle reported an average USDC circulation of $64.87 billion, up from $33.342 billion in FY 2024, while the reserve return rate for FY 2025 was 4.1%, down from 5.0% in FY 2024. The key takeaway is that the company's 2025 revenue growth was driven more by balance growth than by yield tailwinds, as the reserve return rate declined year-over-year rather than increased.
Circle also disclosed operational metrics suggesting USDC is a high-velocity monetary instrument, not a static collateral asset. Management reported FY 2025 USDC minting of $257.5 billion and redemption of $226.1 billion, with a year-end stablecoin market share of 28% based on third-party market cap data and 6.8 million meaningful wallets based on Circle's own definition. The scale of minting and redemption activity relative to the ending supply indicates significant transactional churn, likely related to exchange settlement, liquidity routing, collateral management, and DeFi-related flows, rather than a simple buy-and-hold reserve asset profile. However, Circle does not publicly provide a clear breakdown of USDC usage across these categories, limiting the precision of attribution analysis.
The payment narrative around USDC is becoming more credible, though still in its early stages relative to the reserve income model. Visa has publicly launched USDC settlement capabilities in the U.S. for selected issuer and acquirer partners, enabling the settlement of certain VisaNet obligations in USDC on supported blockchains outside traditional banking hours. Circle highlights this as evidence that USDC can function as a continuous settlement asset, not just a crypto-native trading tool. Even if the current scale remains small relative to Visa's total network volume, the analytical significance is substantial: it is one of the clearest public signals that USDC is being positioned as a component of real-world back-office payment infrastructure.
Distribution into consumer and SMB ecosystems through partner-led conduits is also broadening. Circle announced a partnership with Intuit in December 2025 to enable USDC functionality within products including TurboTax, QuickBooks, and Credit Karma. Strategically, this reinforces Circle's thesis of pushing USDC beyond venues and crypto-native users into mainstream financial workflows. Economically, however, the monetization path remains unclear. Circle has not disclosed pricing, share rates, or revenue-sharing mechanisms tied to this integration, so the existence of distribution progress should not be confused with proof of high-margin payment income.
Another strategic issue is market structure. Circle and Polymarket announced that Polymarket would transition from bridged USDC (USDC.e) on Polygon to native USDC over the coming months. This development is significant because it illustrates Circle's effort to reduce reliance on bridged liquidity and increase the footprint of natively issued USDC across chains. Native issuance improves redemption clarity, reduces some operational complexities around wrapped or bridged forms, and aligns better with a regulation-first model. Simultaneously, the need for such a transition highlights a structural challenge for stablecoins: fragmented liquidity across bridges and chains remains a friction point for adoption, not just a technical footnote.
In summary, USDC's best characterization is a hybrid instrument. First, it is a primary exchange and venue settlement asset; second, it is an on-chain, high-velocity dollar used for collateral, liquidity routing, and crypto market plumbing; third, it is an emerging institutional settlement rail in select integrations. Evidence for payment rail growth is improving, particularly through Visa settlement, Intuit integration, and Circle's broader infrastructure build-out. But Circle's disclosed dominant economic driver remains the reserve income from USDC reserves, not explicit transaction fee monetization from payment activity.
EURC
Even if EURC remains small in direct economic terms, it is strategically significant. The regulatory backdrop in Europe is particularly relevant here. MiCA (Regulation (EU) 2023/1114) came into effect in 2023, with rules for asset-referenced tokens and e-money tokens applicable from June 30, 2024, and the broader regime fully applicable from December 30, 2024. This sequencing is important because euro-denominated stablecoins became "regulatable" earlier than many adjacent crypto asset services, enhancing the ability of regulated issuers and exchanges to support compliant euro stablecoin offerings and boosting institutional confidence.
Circle reported EURC in circulation of €309,608,590 as of December 31, 2025. By March 16, 2026, Circle's EURC page showed circulation of €382.8 million. This implies growth of approximately €73 million, or about 23.6%, from year-end to mid-March. In absolute terms, this remains small relative to USDC, but the growth rate is meaningful and suggests EURC is gaining momentum from a still-small base.
The broader euro stablecoin market size remains very small. Reuters, citing data from the Italian central bank, reported in September 2025 that euro-denominated stablecoins totaled only about $620 million, compared to global stablecoin issuance of around $300 billion at the time. Even accounting for subsequent growth, Circle's reported €382.8 million EURC circulation as of March 2026 suggests EURC is likely one of the dominant euro stablecoins by supply. Nonetheless, in the absence of a recent, high-quality consolidated market dataset as of March 2026, I would avoid stating precise market share, and no such data was found in the reviewed materials.
Circle positions EURC as MiCA-compliant, available on Avalanche, Base, Ethereum, Solana, and Stellar, and states it publishes monthly attestation reports. Strategically, EURC's value to Circle likely exceeds its current direct financial contribution. It helps anchor Circle's regulatory posture in Europe, supports on-chain euro-dollar workflows parallel to USDC, and gives the company an option should European stablecoin policy priorities further intensify. Reporting by Reuters through late 2025 also noted growing focus among European institutions and policymakers on building alternatives to U.S.-dominated stablecoin infrastructure, supporting this optionality thesis.
Over the next 12 to 24 months, EURC is more reasonably viewed as an enabling layer rather than an independent profit driver. Its base remains below €500 million, and Circle does not separately disclose EURC-specific revenue. For EURC to become financially material, three things would likely be needed: a substantially larger euro-denominated float, evidence of payment and treasury adoption beyond crypto-native capital markets, and a distribution path that avoids some of the heavy economic sharing burdens seen in the USDC model. In other words, EURC may already be strategically important but does not yet appear to be financially core.
2025 Financial Analysis and Key Metrics
Circle's FY 2025 financials reinforce the view that the company is first and foremost a reserve income business. The company reported total revenue and reserve income of $2.747 billion for FY 2025, up from $1.676 billion in FY 2024. This FY 2025 figure consisted of $2.637 billion in reserve income and $110 million in other income, compared to $1.661 billion and $15 million, respectively, in FY 2024. Thus, the year-over-year step-change growth was overwhelmingly driven by the expansion of reserve income, not a broad structural shift toward software or transaction fee monetization.
The cost structure is equally important for the underwriting framework. Circle reported distribution and transaction costs of $1.662 billion for FY 2025, up from $1.011 billion in FY 2024. Operating expenses increased from $492 million to $1.179 billion, with compensation expense at $845 million, compared to $263 million in the prior year. This confirms that the gross profitability from higher reserve income is largely shared out through partner economics and then further absorbed by a significantly higher operating cost base.
A useful way to frame operating leverage is to look at Revenue Less Distribution Costs (RLDC), not just top-line revenue. Circle disclosed FY 2025 RLDC of $1.083 billion, up from $659 million in FY 2024, with RLDC margin holding steady at 39% in both years. This flat margin is important: it suggests distribution costs expanded roughly proportionally with reserve income growth, limiting the degree to which higher rates and larger balances translated into structurally better retained economic benefits. In other words, Circle demonstrated growth but did not demonstrate material improvement in the core economic share retained post-distribution.
A clearer signal of operating leverage appears in management's adjusted framework, not the GAAP headline results. Circle disclosed FY 2025 adjusted operating expenses of $508 million and guided to FY 2026 adjusted operating expenses of $570-$585 million (under a revised definition effective Q1 2026). This guidance implies Circle plans to continue investing in growth initiatives, not shifting to a near-term harvest mode. In other words, even if reserve income conditions remain favorable, management appears willing to maintain a higher expense base to build product, infrastructure, and distribution.
The balance sheet also supports a specific interpretation of the business model. As of December 31, 2025, Circle reported $75.068 billion in cash and cash equivalents segregated for the benefit of stablecoin holders and $74.913 billion in stablecoin holder deposits. This structure is consistent with a reserve-backed issuance model built around segregated balances, not a traditional loan-based balance sheet model. Analytically, this structurally positions Circle closer to a narrow-spread business than a high-margin fintech, with the important qualification that the reserves are described as held for the benefit of token holders and are intended to be bankruptcy-remote under Circle's disclosed structure.
Q1 2026 Preview and FY 2026 Bull, Base, Bear Forecasts
Entering Q1 2026, the interest rate backdrop is less favorable than the peak conditions Circle enjoyed earlier in the cycle. On March 16 and 17, 2026, the Effective Federal Funds Rate was 3.64%, and SOFR was 3.65% on March 17, 2026. Circle's own sensitivity framework used a 3.64% average as of December 2025 as a reference point. This implies a reserve return environment in early 2026 is below the 5.0% reserve return rate disclosed for FY 2024 and closer to year-end 2025 levels, meaning balance growth must do more work if Circle is to maintain reserve income growth.
The starting point for Q1 2026 is at least directionally favorable for balances. Circle disclosed USDC circulation of $79.2 billion as of March 16, 2026, up from the $75.266 billion reported at 2025 year-end. EURC also grew from €309.6 million at year-end to €382.8 million on March 16, 2026. This setup suggests Q1 average stablecoin balances likely improved from Q4 exit levels, partially offsetting the lower yield mechanism.
Management's guidance for FY 2026 points to continued diversification but not a change in the foundational economic model. Circle guides to other income of $150-$170 million, an RLDC margin of 38% to 40%, and adjusted operating expenses of $570-$585 million. The signal here is twofold: first, management expects non-reserve income to grow; second, even by their own guidance, these revenues remain small relative to the reserve income engine.
Bull Case: In a bull case, USDC circulation expands steadily through Q1 and Q2, supported by growth in institutional settlement usage, higher on-chain turnover, and incremental distribution wins. In this outcome, reserve income remains resilient even if realized yields hold at the short-end levels seen in late 2025 and early 2026. Distribution costs also rise, but the retained economic benefit post-distribution grows sufficiently to absorb the higher planned operating expenses while maintaining margins at or near guidance levels. This is essentially a "balance growth offsets rate compression" case. Supported by current balance trends and a still-expanding ecosystem, this is plausible but still contingent on sustained transaction volume and adoption momentum.
Base Case: In a base case, USDC circulation growth slows to low single digits quarter-over-quarter as trading activity and DeFi usage normalize. Reserve returns anchor around the short-end, roughly in line with EFFR and SOFR around 3.5%. In this setup, reserve income may hold steady or grow slightly with average balances, but distribution costs remain structurally high as the partner sharing model does not disappear. RLDC margin thus holds within the company's guided 38% to 40% range, with modest revenue progression but limited structural margin expansion.
Bear Case: In a bear case, USDC circulation stagnates or declines due to risk-off flows, exchange-driven outflows, or market share pressure, while rates slide further from already reduced levels. Under Circle's own sensitivity framework, lower yields would reduce reserve income and mechanically reduce some distribution costs, but the net effect would still be negative for RLDC. This would become more significant as Circle enters FY 2026 with a higher planned expense base, meaning weak balances and weak yields would expose the business more directly to partner concentration and operating cost rigidity.
Strategic Positioning and Competition
Circle is best underwritten as a regulated digital currency network operator with two tiers: a core of issuance and reserve management that dominates financially today; and a broader perimeter of applications, interoperability, and developer services that is strategically important but not yet economically dominant. This distinction is important because, until non-reserve revenue becomes materially larger, Circle's valuation, earnings sensitivity, and risk profile remain tightly linked to monetary policy and stablecoin market structure.
The most significant example of current strategic option value is the Circle Payment Network (CPN). Circle introduced the concept in April 2025 and disclosed that as of February 20, 2026, 55 financial institutions had joined, 74 were undergoing qualification, and annualized transaction volume over the past 30 days had reached $5.7 billion. These are meaningful early indicators of network formation and institutional interest. However, in the absence of disclosed share rates, revenue contribution, or profit profile, CPN is easier to justify strategically than financially.
A second credible non-reserve vector is interoperability tools. Circle disclosed it launched CCTP V2 in March 2025 and that it can generate transaction fees when customers opt for the fast transfer feature. This is one of the stronger non-reserve monetization paths because it prices specific technical capability, not just hoping usage translates into value. Even so, Circle's disclosed FY 2025 transaction revenue line remains small, so the contribution relative to reserve income is still negligible for now.
Circle's acquisition-oriented expansion into adjacencies through Hashnote and USYC is also strategically noteworthy. Circle describes USYC as the on-chain representation of money market fund shares primarily used for collateral purposes in digital asset markets and discloses it earns fees including performance fees. This is a logical adjacency to USDC because it addresses yield-bearing collateral and margin needs that the stablecoin itself cannot fully solve. But the market still lacks separate public disclosure on USYC assets, revenue, or profitability, so it is currently more of a strategic building block than a fully underwritable standalone driver.
On the competition front, Circle's most direct dollar stablecoin rival remains Tether. Reuters reported in February 2026 that USDT's issuance was approximately $1.84 trillion, highlighting Tether's substantial scale advantage. However, Circle's differentiation remains clear: public company disclosure transparency, reserve asset constraints more closely aligned with emerging regulation, and a stronger positioning within regulated institutions and payment networks. In this sense, Circle's competitive advantage is less about absolute scale and more about institutional credibility and regulatory transparency.
Another competitor is PayPal's PYUSD, which PayPal announced would be available in 70 markets globally. PYUSD is strategically relevant because it is embedded within a global consumer and merchant payment distribution network, a very different go-to-market advantage compared to Circle's exchange- and infrastructure-heavy footprint. Circle's current advantages remain deeper USDC liquidity, greater scale, and stronger crypto market integration; PYUSD's differentiation is native wallet and merchant distribution within a mainstream payment platform.
In Europe, the competitive landscape could become more challenging over time. Reuters reported that a consortium of major European banks, including ING, UniCredit, and later BNP Paribas, formed a company planning to launch a euro stablecoin in the second half of 2026, while policymakers have also publicly discussed strengthening euro-denominated digital currency to counter dollar dominance. This poses a substantive medium-term competitive threat to EURC, as a bank-led euro stablecoin could combine regulatory credibility with embedded corporate and banking distribution. However, as of March 2026, this remains more a future competitive risk than an immediate supply-side displacement.
Conclusion
Circle's FY 2025 performance reaffirms the底色 of its reserve income model. While USDC transaction volume and new initiatives like CPN improve the strategic narrative, their financial significance is not yet comparable to reserve income. Therefore, the core evaluation framework should still focus on: balance growth, interest rate sensitivity, and the distribution cost structure tied to Coinbase.
