S&P Global Ratings Revolutionizes Stablecoin Assessment with Chainlink On-Chain Integration

Traditional finance meets blockchain as S&P Global Ratings takes its stablecoin scoring system on-chain through strategic Chainlink partnership.

Breaking Down the Wall Street-Blockchain Bridge

S&P's move marks the first major credit rating agency to deploy its assessment framework directly on blockchain infrastructure. The integration leverages Chainlink's oracle network to deliver real-time stablecoin ratings directly to smart contracts and DeFi protocols.

No more waiting for quarterly reports or manual updates—the scoring system now operates with blockchain's signature transparency and immediacy. Financial institutions can access verified stablecoin ratings programmatically, while DeFi platforms gain institutional-grade risk assessment tools.

The partnership represents another step toward traditional finance's reluctant embrace of crypto infrastructure—because apparently, even rating agencies can't ignore the efficiency gains of blockchain technology anymore. Because nothing says 'trust' like needing multiple billion-dollar corporations to verify what should be transparent by design.

Smart contracts now have direct access to S&P's stablecoin evaluations, potentially transforming how DeFi protocols manage risk and collateral. The move could finally bring the 'stable' back to stablecoins—or at least provide better warning signs before the next algorithmic collapse.

S&P Global Ratings distributes risk score through Chainlink 

The S&P Stablecoin Stability Assessment is not an official credit rating, but assigns a value of 1-5 based on the token’s ability to maintain its value relative to their respective fiat currencies. As adoption of stablecoin accelerates, the available data is now directly integrated with accessible on-chain infrastructure. 

“The launch of SSAs on-chain through Chainlink underscores our commitment to meeting our clients where they are,” said Chuck Mounts, Chief DeFi Officer at S&P Global. 

“By making our SSAs available on-chain through Chainlink’s proven oracle infrastructure, we’re enabling market participants to access our assessments seamlessly using their existing DeFi infrastructure, enhancing transparency and informed decision-making across the DeFi landscape,” said Mounts.  

The stablecoin assessment includes market value and custody risks, collateral requirements, and liquidation mechanisms where applicable. S&P Global Ratings also explores governance, regulatory requirements, redeemability and liquidity, as well as technology and third-party dependencies. The assessment points apply to both asset-backed and algorithmic stablecoins. 

Chainlink to launch stablecoin rankings on Base

Sergey Nazarov, co-founder of Chainlink stated that it will be able to deliver the stablecoin rankings to some of the world’s biggest institutions. Following the news, LINK tokens traded within their usual range at around $18.30, following the recent market downturn from a local peak of over $21. 

Chainlink retains its leading position as a data provider for the on-chain economy, securing nearly $100B in DeFi value. Chainlink has also collaborated with other institutions in traditional finance, including Swift, Euroclear, J.P. Morgan, Fidelity, UBS, and Mastercard. 

The stablecoin assessments will be published on Base, the ethereum L2 chain, with expansion to other networks based on market demand and client feedback. 

The published rankings arrive as the supply of stablecoins broke above $300B, with over 70 different alternatives. In 2025, USDT and USDC remain the leading assets, but USDC has spread its ecosystem to a larger number of chains to serve niche use cases and bring liquidity to DeFi communities.

Initially, the stablecoin assessment prepared reports on eight major stablecoins. Over time, the types of tokens increased, making the choice of assets more difficult for DeFi protocols. Stablecoins remain key to trading and lending, with even more attention paid to their risk of de-pegging and causing liquidation cascades.
