Coin Metrics examines two pressing developments reshaping crypto fundamentals: the evolving economics of stablecoin firm Circle (NYSE:CRCL) and a sharp liquidity crisis triggered by a major exploit in the restaking sector. Circle, which went public nearly a year ago, continues to dominate headlines as investors scrutinize its transition from a high-yield reserve business to a broader payments platform.
According to the research report, the company posted approximately $2.7 billion in revenue for fiscal year 2025—a 64% year-over-year increase—driven almost entirely by interest earned on USDC reserves.
USDC’s circulating supply reached $75.3 billion by year-end, holding a steady 28% share of the stablecoin market, while adjusted transfer volumes surged roughly 320%.
Subscription and service fees added a modest $110 million, signaling early diversification, but reserve income still accounted for 96% of the total.
After sharing proceeds with distribution partners, Circle’s revenue less distribution costs (RLDC) stood at $1.08 billion, delivering a 39% margin.
The firm’s profitability remains highly sensitive to interest rates. Coin Metrics estimates that a 100-basis-point decline in yields would slash annual revenue by 25–30%.
Using FY2025 as a baseline (roughly 4.1% effective yield on an average $65 billion supply), the report models various scenarios.
At sustained higher rates of 4–4.5%, combined with USDC supply growth to $90–110 billion, reserve income could exceed $4 billion.
Moderate easing to 3–3.5% (aligned with current Fed projections) would allow supply expansion to keep income roughly flat.
However, deeper rate cuts to around 2.5% could reduce income 30–50% even with strong growth in circulation.
A critical variable is the August 2026 renewal of Circle’s revenue-sharing agreement with Coinbase.
Under current terms, Coinbase receives all interest on USDC held on its platform plus half the interest earned elsewhere—capturing roughly 51% of gross reserve income in 2025.
Renewed terms could improve Circle’s take-rate through diversified distribution, but any weakening would heighten exposure to lower yields or slower USDC adoption.
Emerging fee streams, including the Circle Payments Network and Cross-Chain Transfer Protocol (CCTP), remain small yet promising, though potential provisions in the CLARITY Act could indirectly constrain yield-sharing programs.
On the DeFi side, Coin Metrics highlights a severe liquidity shock stemming from a roughly $290 million exploit on April 18.
An attacker exploited a misconfigured LayerZero decentralized verifier network (DVN) in KelpDAO’s rsETH cross-chain bridge, minting approximately 116,500 unbacked rsETH—about 18% of total supply.
Coin Metrics pointed out that the fake tokens were deposited as collateral, primarily on Aave, to borrow WETH.
This rapidly pushed Aave’s v3 WETH market to 100% utilization, sparking a broader “bank run” with utilization rates spiking across USDC and USDT pools and more than $9 billion in deposits withdrawn.
The incident underscores how interconnected DeFi risks—spanning bridges, restaking derivatives, and lending protocols—can cascade rapidly when collateral curation fails.
Coin Metrics describes Circle’s future as somewhat of balancing act between rate-sensitive reserve income and growing usage-driven revenue, while the KelpDAO event serves as a reminder of systemic vulnerabilities in today’s layered DeFi infrastructure. As the web3 sector evolves in 2026, both traditional financial metrics and on-chain resilience will determine long-term trajectories of crypto industry participants.
