BREAKING: S&P Global Partners with Chainlink to Bring $300B Stablecoin Ratings On-Chain

Traditional finance meets decentralized oracle networks in a landmark collaboration that could reshape crypto credibility.

The Rating Revolution Begins

S&P Global just dropped a seismic announcement—they're publishing ratings for $300 billion worth of stablecoins directly on-chain through Chainlink's oracle network. This isn't just another partnership; it's institutional validation hitting the blockchain where it matters most.

No more checking separate websites or waiting for quarterly reports. Real-time rating updates will flow directly into smart contracts, giving DeFi protocols instant access to trusted credit assessments. The move effectively bridges the gap between traditional financial due diligence and blockchain's transparency requirements.

Stablecoins representing nearly the entire market cap now face the music—public, immutable scrutiny that either validates their reserves or exposes the empty promises. Finally, someone's bringing actual financial oversight to the wild west of digital assets—though Wall Street will probably find a way to charge fees for reading the on-chain data anyway.

• S&P Global Ratings joins forces with Chainlink to publish Stablecoin Stability Assessments (SSAs) on-chain for the first time.
• The initiative arrives as the stablecoin market surpasses $300 billion amid new U.S. regulations.
• The collaboration aims to bring transparency and institutional confidence to DeFi and on-chain financial systems.

S&P Global Ratings has entered a major collaboration with Chainlink, marking a new phase for blockchain-based finance. The partnership enables the publication of S&P’s Stablecoin Stability Assessments (SSAs) on-chain through Chainlink’s DataLink service. This MOVE allows institutions, DeFi protocols, and developers to access real-time stablecoin stability data directly from smart contracts.

The timing aligns with a growing stablecoin sector that now exceeds $301 billion in market capitalization, up from $173 billion last year. The introduction of the GENIUS Act in July 2025 gave the U.S. its first regulatory framework for stablecoins, paving the way for large-scale institutional involvement.

With on-chain SSAs, investors can now evaluate risks such as liquidity, custody, and asset backing, helping them determine a stablecoin’s ability to maintain its fiat peg.

S&P’s system rates stablecoins on a scale from 1 (very strong) to 5 (weak), offering clarity for both traditional and decentralized investors seeking risk insights before adopting stablecoin-based products.

S&P Uses Chainlink to Add Ratings to Blockchain

The partnership utilizes Chainlink’s proven infrastructure that has supported over $25 trillion in on-chain transaction volume and secures close to $100 billion in DeFi TVL. By bringing its ratings on chain, S&P Global Ratings indicates that it will address the transparency requirements of institutional investors entering digital markets.

S&P’s Chief DeFi Officer, Chuck Mounts, noted that the move serves clients seeking trustworthy data in their current DeFi configurations. With the DataLink of Chainlink, banks may incorporate the evaluation of S&P into self-executing smart contracts in real time for enhanced risk management.

This integration may raise confidence levels of the 2,400+ institutions in the Chainlink ecosystem, allowing for greater stablecoin SAFE adoption in lending, settlement, and trade.

Expanding S&P’s Digital Finance Footprint

The new step is the latest in S&P’s increased activity in decentralized finance. Over the past few years, the company has launched crypto indexes, tokenized treasury bond grades, and DeFi-oriented indexes.

Now, SSAs are possible on a blockchain chain, so regulated institutions have a safe way to play blockchain markets thanks to S&P Global Ratings.

First released on Coinbase’s Base network, the service will be launched on additional blockchains dependent on demand. S&P currently evaluates 10 prominent stablecoins, such as USDT, USDC, and USDS/DAI by Sky Protocol.

Providing verified data directly to the blockchain, the partnership creates a bridge between traditional finance and DeFi and forges a clearer and more responsible digital economy.
