Circle reported Q2 2026 total revenue and reserve income of $701 million. This figure grew 7% compared to Q2 2025. USDC in circulation reached $73.3 billion at the end of the quarter. This amount increased 19% year-over-year. Onchain transaction volume for USDC reached $14.8 trillion in the second quarter. This volume grew 151% over the previous year. Net income from continuing operations reached $48 million. This amount increased $530 million year-over-year because of lower stock-based compensation impacts following the June 2025 IPO.
Circle faces intense interest rate risk.
The revenue model and interest rate vulnerability
The company earns 95% to 99% of its revenue from interest generated by investing USDC reserves in short-term U.S. Treasury securities. This makes the company highly dependent on the yield of the front end of the curve. When the Federal Reserve lowers interest rates, Circle’s primary revenue stream shrinks. The company reported an adjusted EBITDA of $143 million for the second quarter. This amount grew 8% year-over-year. However, this growth only occurred because USDC in circulation grew by 25%.
The high concentration of revenue in short-term interest income makes Circle’s earnings highly sensitive to the Federal Reserve’s decisions. Unlike traditional banks, Circle cannot easily reprice loans or manage a diverse mix of assets to mitigate duration risk. The GENIUS Act restricts the specific types of assets a stablecoin issuer can hold. This law limits holdings to USD, Treasury securities with a remaining maturity of 93 days or less, and overnight reverse repos collateralized by Treasuries. You should monitor the volatility of the 1-month T-bill yield.
Yield compression and the Treasury market
Stablecoin demand now impacts the sovereign debt market. The total stablecoin market capitalization reached $322 billion in May 2026. Tether holds $141 billion in Treasury exposure. Circle manages $79 billion in USDC reserves. These reserves link 84% to Treasuries through direct holdings and collateralized repurchase agreements. The GENIUS Act, signed July 18, 2025, forces all regulated issuers to maintain 100% reserve backing using short-duration assets. This concentration creates massive demand for the front end of the Treasury curve.
A stablecoin demand shock corresponding to a 1% increase in combined USDT and USDC market capitalization leads to a statistically significant decline in the 1-month T-bill yield of 0.42 basis points, according to researchers at the IMF. The Bank for International Settlements found that a two-standard-deviation stablecoin inflow lowers 3-month T-bill yields by 2.5 to 3.5 basis points. During periods of bill scarcity, these inflows compress yields by 5 to 8 basis points. As the stablecoin market grows toward a projected $2 trillion, this demand will likely suppress yields further.
Competition in the stablecoin landscape
Tether leads the market. Tether’s USDT circulation reached approximately $189 billion in May 2026. USDC circulation reached $78 billion in May 2026. Tether launched USA in January 2026 to compete for the U.S. institutional market. This new product aims for compliance with the GENIUS Act. PayPal and Ripple also compete for market share with PYUSD and RLUSD.
The competitive landscape creates pressure on margins. While USDC maintains a regulatory advantage, USDT maintains higher liquidity. Traders often prefer the deepest liquidity pools for high-frequency flows. Circle must narrow the volume gap with Tether to remain the preferred choice for market makers. The market remains divided between highly regulated assets and those with higher liquidity.
Payment rails and the Stripe integration
Stripe expands stablecoin access for global commerce. Stripe helps Shopify merchants in 34 countries accept USDC payments. These merchants use Stripe Connect to manage payments for multiple beneficiaries. Customers pay in USDC on the Base network using their preferred crypto wallet. Stripe allows merchants to receive these funds in their local currency via their bank accounts.
| Gateway | Fee | Payout | Chains |
|---|---|---|---|
| Stripe | 1.5% | USD or USDC | Solana, Ethereum, Polygon, Tempo |
| Coinbase Commerce | 1.0% | USDC (USD via add-on) | Base, Ethereum, Polygon, Solana |
| BitPay | 1.0% | USD bank or crypto | Ethereum, Polygon, Bitcoin + 10 others |
| PayPal Crypto | ~1.5% | PYUSD or USD | Ethereum, Solana |
Stablecoin-linked cards now process roughly $18 billion in annualized volume. Visa carries more than 90% of on-chain crypto card volume. This dominance stems from early alignment with crypto-native issuers like Rain and Reap. These full-stack issuers manage their own settlement and capture more interchange. They issue cards directly and manage the conversion of crypto to fiat at the moment of spend.
Institutional infrastructure and the Arc network
Circle plans to launch its Arc network on the public mainnet on September 16. The network includes over 100 ecosystem and institutional builders. A founding third-party validator cohort includes BlackRock, DTCC, Galaxy, Global Payments, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered, Sumitomo Corporation, and Visa. These institutions provide the infrastructure that secures the network.
BlackRock expects to deploy its BUIDL fund on the Arc network. DTCC will enable the tokenization of DTC-custodied assets on Arc. BNY expanded its partnership with Circle to add USDC minting and redemption to its Digital Asset Custody platform. Standard Chartered also launched integrated access to USDC minting and redemption. This allows institutional clients to convert between fiat and USDC through a single bank-led onboarding experience.
The Agent Stack launched in May 2026. This platform currently hosts over 900 paid services. Approximately 99.3% of the x402 agent-payment volume settles in USDC. Circle aims to enable agents to earn through this infrastructure.
The banking displacement risk
Stablecoins create significant competition for traditional bank deposits. Standard Chartered estimated in January 2026 that stablecoins could drain $100 billion from U.S. bank deposits. Citigroup projected deposit displacement between $182 billion and $908 billion by 2030. This shift occurs because stablecoin reserves sit in Treasury bills and bank deposits outside the traditional banking system.
Large institutions capture most of this movement. Stablecoin issuers custody their reserves at large regulated banks rather than community institutions. As deposits migrate to stablecoins, they migrate toward the largest custodians. Community banks face a disproportionate share of the deposit risk. They lack the tools to compete with the scale of global asset managers.
JPMorgan, Bank of America, Citigroup, and Wells Fargo are exploring joint stablecoin initiatives. Wells Fargo filed a trademark application for WFUSD in March 2026. This filing covers crypto-payment processing and digital asset trading. SoFi Bank launched SoFiUSD, a fully reserved dollar-pegged stablecoin.
The regulatory environment
The GENIUS Act established a federal framework for stablecoins in July 2025. It requires 100% reserve backing for all regulated issuers. The law also mandates monthly public disclosures of reserve composition. Circle received approval from the U.S. Office of the Comptroller of the Currency to establish Circle National Trust. This makes Circle one of the first stablecoin issuers to hold a federal bank charter.
This charter allows Circle to manage the USDC reserve directly. It also enables federally regulated digital asset custody. The New York Department of Financial Services also approved Circle to open a digital asset-focused limited purpose trust company. These approvals strengthen the regulatory moat for Circle.
Will regulatory changes in Europe eventually create a similar liquidity divide between USDC and euro-denominated stablecoins? The European Central Bank expressed concerns that easing euro stablecoin regulations could destabilize bank funding. EU policymakers worry about the impact on monetary policy transmission.
The future of the Circle IPO
Circle’s stock volatility remains high. The stock reached a record high of $300 in late June 2025. It fell to a closing price of $113 by May 22, 2026. This represents a 62% decline from the peak. The company’s Q1 2026 revenue of $694 million missed consensus forecasts by approximately 3%.
Circle’s ability to scale depends on its capacity to outrun the revenue losses from declining Treasury yields. The market’s interest in the company depends on whether it can convert regulatory clarity into transaction volume. Stablecoin transaction volume reached $33 trillion in 2025. USDC led this volume with $18.3 trillion. Circle’s success hinges on its ability to maintain market share as the yield advantage of stablecoins erodes.
