S&P Global partners with Chainlink to boost stablecoin confidence - Crypto Economy

TL;DR

• Stablecoin ratings: S&P Global and Chainlink launched onchain Stablecoin Stability Assessments, rating coins from 1 to 5 based on peg strength.
• Institutional adoption: Chainlink’s DataLink delivers S&P’s trusted evaluations onchain, giving institutions real-time risk insights.
• Market outlook: With stablecoins at $300 billion and projected to hit $2 trillion by 2028, demand for transparent risk profiles is set to grow.

S&P Global Ratings has entered a landmark collaboration with blockchain oracle provider Chainlink to deliver onchain stablecoin stability assessments, aiming to strengthen institutional trust in the $300 billion stablecoin market. The initiative introduces a standardized framework for evaluating how well stablecoins maintain their peg, a critical factor for adoption across traditional finance and decentralized finance ecosystems.

Launch of Stablecoin Stability Assessments

The Stablecoin Stability Assessments (SSAs) debuted on Ethereum’s layer-2 network Base, with plans to expand to other blockchains depending on demand and client feedback. Each stablecoin is rated on a scale from 1 (very strong) to 5 (weak), reflecting its ability to hold value relative to fiat currencies. By embedding these ratings directly into blockchain infrastructure, institutions gain real-time access to risk profiles that can guide investment and compliance decisions.

Chainlink’s DataLink Integration

The assessments are powered by Chainlink’s DataLink, an institutional-grade data publishing service that ensures tamper-resistant delivery of S&P’s evaluations. This integration marks the first time S&P Global Ratings, long trusted for corporate and sovereign credit ratings, is accessible onchain for decentralized applications. Chainlink co-founder Sergey Nazarov emphasized that the move provides a secure and compliant foundation for institutions scaling into digital assets, bridging the gap between traditional finance and blockchain-based markets.


Market Growth and Regulatory Context

The stablecoin sector recently surpassed $300 billion in circulation and could expand to $2 trillion by 2028, according to U.S. Treasury estimates. With the GENIUS Act establishing a regulatory framework for stablecoins, demand for transparent and standardized risk assessments is expected to rise. Institutions now have tools to evaluate both fiat-backed and algorithmic stablecoins, enabling more informed decisions in a market often scrutinized for volatility and systemic risk.

Expanding Chainlink’s Institutional Reach

This partnership adds to Chainlink’s growing roster of collaborations with major financial players, including Swift, Euroclear, JPMorgan, Fidelity, UBS, and Mastercard. The U.S. government has also leveraged Chainlink to publish economic data onchain, underscoring its role as a trusted oracle provider. Having already secured nearly $100 billion in DeFi total value locked and enabled over $25 trillion in transaction value, Chainlink’s integration with S&P Global Ratings further cements its position as a critical infrastructure provider for digital markets.
