In a landmark move uniting traditional finance & decentralized systems, S&P Global Ratings has partnered with Chainlink Labs to deliver its Stablecoin Stability Assessments (SSAs) directly to smart contracts through Chainlink’s institutional-grade DataLink service.

Bringing Institutional-Grade Risk Data On-Chain

Through Chainlink’s DataLink, these assessments can be securely published to blockchain networks, enabling smart contracts, lending protocols, & institutional investors to integrate S&P’s independent risk evaluations into their automated processes.

According to 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, enhancing transparency & informed decision-making across the DeFi landscape.”

Why This Matters for Stablecoins & DeFi

S&P’s SSAs aim to bring clarity, trust, & comparability by evaluating stablecoins on parameters like asset quality, governance, liquidity, & redemption mechanisms.

The timing is strategic: the stablecoin market has grown to $301 billion as of October 2025 (up from $173 billion a year earlier). This coincides with the GENIUS Act, the first U.S. federal stablecoin regulatory framework, providing institutional clarity for on-chain finance.

Inside the Collaboration: S&P Global & Chainlink

The collaboration leverages Chainlink’s data infrastructure, which powers over $25 trillion in transaction value and secures nearly $100 billion in DeFi total value locked (TVL). S&P’s assessments are first launched on Base, Coinbase’s Layer-2 built on Ethereum, with further network expansion planned based on demand.

Sergey Nazarov, Co-Founder of Chainlink, said:

“This integration empowers the world’s largest institutions to adopt stablecoins at scale, establishing a secure & compliant foundation for digital markets.”

This partnership continues S&P’s momentum in blockchain analytics:

• 2021: Launch of S&P Digital Market Indices for Bitcoin & Ethereum.
• 2023: Release of Stablecoin Stability Assessment framework.
• 2025: Ratings for tokenized treasury funds & DeFi protocols like Sky Protocol.
• 2025: SSAs go on-chain via Chainlink.

The S&P Global–Chainlink collaboration represents a pivotal step toward institutional-grade DeFi, merging legacy financial standards with blockchain-native infrastructure.
