S&P Global Ratings and Chainlink Collaboration Brings S&P's Stablecoin Stability Assessments On-Chain
Industry First: S&P Global Ratings' Stablecoin Risk Assessments Now Available Directly to Smart Contracts via Chainlink's Institutional-Grade DataLink Publishing Service, Powering the Next Generation of Institutional DeFi
NEW YORK, Oct. 14, 2025 /PRNewswire/ -- S&P Global (NYSE:SPGI) today announced a collaboration between S&P Global Ratings, the world's leading provider of credit ratings, benchmarks and analytics, and Chainlink, the industry-standard oracle platform bringing the capital markets on-chain, to deliver S&P Global Ratings' Stablecoin Stability Assessments (SSAs) on-chain via DataLink—an institutional-grade data publishing service powered by the Chainlink data standard. This initiative makes S&P Global Ratings' deep, independent stablecoin risk analysis directly accessible within decentralized finance (DeFi) protocols and smart contracts for the first time.
The on-chain SSAs provide real-time access to S&P Global Ratings' comprehensive stablecoin stability assessments, which, while not credit ratings, evaluate stablecoins on a scale from 1 (very strong) to 5 (weak) based on their ability to maintain stable value relative to fiat currencies. As institutional adoption of digital assets accelerates, the ability to access real-time risk assessments directly within blockchain infrastructure has become crucial for market participants. The collaboration enables DeFi protocols, lending platforms, and institutional investors to incorporate S&P Global Ratings' robust analytical risk assessments directly into their automated decision-making processes.
"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."
As a turnkey service, DataLink empowers data providers like S&P Global Ratings to publish data to blockchains and on-chain markets in a secure and reliable manner—without the need to build or maintain new infrastructure.
"I'm very excited that S&P Global Ratings is leveraging Chainlink to bring its Stablecoin Stability Assessments on-chain for the first time, empowering the world's largest institutions to adopt stablecoins at scale," said Sergey Nazarov, Co-Founder of Chainlink. "By making its SSAs available on-chain, Chainlink enables S&P to extend its reach directly into the digital asset economy. S&P Global Ratings is one of the world's most trusted providers of credit ratings, relied upon by the largest banks, asset managers, and governments. This unlocks a critical framework for institutions adopting stablecoins at scale, enabling a more secure and compliant foundation for digital markets."
The collaboration leverages Chainlink's infrastructure, which has powered the majority of the on-chain economy for more than half a decade, enabling over $25 trillion in transaction value while actively securing nearly $100 billion in DeFi TVL. Chainlink also has an established track record working with major financial institutions including Swift, Euroclear, J.P. Morgan, Fidelity, UBS, and Mastercard. The on-chain SSAs initially launch on Base, the Ethereum Layer 2 blockchain incubated by Coinbase, with expansion to additional networks planned based on market demand and client feedback.
The launch comes at a pivotal moment in the evolution of digital assets. As of October 2025, the stablecoin market's capitalization reached $301bn, marking a substantial increase from $173bn a year ago (Source: Coingecko). The signing of the GENIUS Act into law on July 18, 2025, established the first federal regulatory framework for stablecoins in the United States, providing clarity for institutional participants. The availability of S&P Global Ratings' SSAs on-chain further supports market participants as they develop and adopt easy-to-use DeFi solutions that meet the high-risk management standards that regulated institutions require to move capital on-chain at scale.
