Quick Summary – TLDR:
- S&P Global Ratings has partnered with Chainlink to bring its Stablecoin Stability Assessments (SSAs) on-chain.

What Happened?
S&P Global Ratings, the credit analytics giant behind benchmarks like the S&P 500, has teamed up with Chainlink to make its stablecoin risk assessments available on-chain. These Stablecoin Stability Assessments, while not credit ratings, provide an independent evaluation of stablecoins’ ability to maintain a stable value and are now accessible directly through decentralized finance applications.
We’re excited to announce that @SPGlobalRatings—the leading credit rating agency relied on by 95% of the top 20 global institutional investors—is collaborating with Chainlink to publish its Stablecoin Stability Assessments (SSAs) onchain for the first time via DataLink.… pic.twitter.com/aSAkAc4msp

Real-Time Risk Ratings Enter DeFi
For the first time, decentralized applications, institutional investors, and lending protocols can access S&P Global Ratings’ SSAs in real-time, embedded directly into smart contracts via Chainlink’s DataLink infrastructure. This integration eliminates the need for custom infrastructure, allowing existing DeFi platforms to seamlessly plug into trusted risk analytics.
- SSAs are scored on a 1 to 5 scale, with 1 meaning very strong stability and 5 indicating weak stability.
- The framework evaluates 10 major stablecoins, including USDT, USDC, and Sky Protocol’s USDS/DAI.
- Ratings consider elements like collateral quality, liquidity management, redeemability, regulatory compliance, and governance.
Chuck Mounts, Chief DeFi Officer at S&P Global, said, “The launch of SSAs on-chain through Chainlink underscores our commitment to meeting our clients where they are.” He added that this move enhances transparency and decision-making for institutions moving into DeFi.
Chainlink’s Proven Infrastructure
Chainlink’s reputation in decentralized data services is well-established. The platform has helped secure nearly $100 billion in total value locked across DeFi and processed over $25 trillion in on-chain transactions. Its clients include J.P. Morgan, Mastercard, Swift, Fidelity, and UBS, underscoring its role in bridging the gap between traditional finance and blockchain ecosystems.
Sergey Nazarov, Chainlink co-founder, commented:
The SSAs are initially being launched on Base, Coinbase’s Ethereum Layer 2 network, with plans to expand to other blockchain networks based on demand.
A Strategic Step in S&P’s Digital Finance Expansion
This collaboration is just the latest chapter in S&P Global’s ongoing digital asset strategy, which began in 2021 with the launch of its first crypto indices. Since then, the company has consistently deepened its presence in DeFi and blockchain analytics:
- 2023: Debut of Stablecoin Stability Assessments covering USDC, USDT, and more.
- 2025: Ratings assigned to tokenized treasury funds and DeFi protocols like Sky Protocol.
- October 2025: SSAs go live on-chain via Chainlink.
S&P’s expanding role in digital finance is backed by its analyst-driven methodology and commitment to providing transparent, data-rich tools that support risk-aware decision-making.
SQ Magazine’s Takeaway
I think this move is huge. Finally, we’re seeing a heavyweight like S&P Global bringing its trusted research tools into the decentralized world, and it’s doing so with a partner that knows DeFi inside out. This is not just about ratings. It’s about giving DeFi platforms the kind of risk insights that big banks and asset managers rely on daily. If DeFi wants to grow up and scale, it needs trust, standards, and data. And that’s exactly what this collaboration delivers.
