New BlackRock Report Reveals Historic Shift in Crypto: Ethereum Emerges as Sole Blockchain Controlling Settlement Layer
By Andjela Radmilac | January 10, 2026
A groundbreaking report from BlackRock’s Investment Institute highlights a historic transformation in the cryptocurrency landscape, underscoring a consolidation of power in the settlement layer of the market. According to BlackRock’s 2026 Global Outlook, stablecoins are transitioning from niche trading tools to foundational infrastructure that bridges traditional finance with digital liquidity — and Ethereum is positioned to become the dominant blockchain anchoring this settlement layer.
Stablecoins Evolve Beyond Trading Convenience
Initially, stablecoins like USDT and USDC served as convenient dollar-pegged tokens for traders needing a reliable unit of account in volatile markets. They enabled users to park funds in crypto form without reverting to traditional fiat currencies, providing 24/7 liquidity for crypto exchanges independent of banking hours.
However, the BlackRock report signals a fundamental evolution. Stablecoins have matured beyond their initial role and are now rapidly integrating into mainstream payment systems. As regulators establish clearer frameworks—most notably the US GENIUS Act signed into law in July 2025, which provides a federal regulatory structure for payment stablecoins with reserve and disclosure requirements — stablecoins are beginning to serve as vital rails for everyday finance.
Samara Cohen, BlackRock’s global head of market development, is quoted in the report saying, "Stablecoins are no longer niche. They’re becoming the bridge between traditional finance and digital liquidity."
Regulation and Market Scale Drive Adoption
Ambitious regulatory developments are critical in this evolution, particularly in the United States. The GENIUS Act’s clear guidelines on stablecoin operations have lowered compliance uncertainties for banks, merchants, and payment networks, encouraging broader implementation.
The total stablecoin market value reached approximately $298 billion as of January 5, 2026, with USDT and USDC maintaining leadership in market capitalization. This size, combined with regulatory clarity, has triggered stablecoins’ use in areas previously uncommon, including the back-office operations of global payment giants.
In December 2025, Visa announced the launch of USDC settlement services in the United States. Its partner banks settled transactions over Solana’s network — a move Visa described as an effort to modernize its settlement infrastructure by enabling faster funds movement, weekend availability, and improved resilience. This represents stablecoins stepping into the traditional finance settlement space, where operational reliability is critical.
Ethereum: The Settlement Layer Powerhouse
A key question raised by BlackRock’s report is where stablecoins “live” within the blockchain ecosystem as transaction volumes and complexity increase. While many blockchains offer fast transaction speeds, the report emphasizes that Ethereum has become the preferred base layer blockchain for stablecoin settlement.
Ethereum’s strength is not necessarily in speed or low transaction fees but in the security, finality, and governance that it provides. Its architecture supports rollups and Layer 2 solutions, which handle execution off-chain while retaining Ethereum as the final arbiter of security and settlement. This separation of execution and settlement functions positions Ethereum as the blockchain best suited to handle the increasingly complex financial activities supported by stablecoins, such as collateralization, tokenized money markets, treasury management, and cross-border payments.
Ethereum’s role as the settlement "court" lends trust and predictability critical for institutions which require robust custody integrations and compliance-ready smart contract infrastructure.
Tokenization Solidifies Ethereum’s Dominance
Beyond stablecoins, tokenization of real-world assets (RWAs) is another key development advancing Ethereum’s dominance. Tokenization involves issuing blockchain-based representations of traditional financial assets, such as treasury bills or money-market funds.
According to data compiled by RWA.xyz and cited in BlackRock’s report, roughly $12.5 billion in tokenized RWAs currently reside on Ethereum—a commanding 65% market share. BlackRock itself has contributed to this momentum by launching its own tokenized money-market fund called BUIDL initially on Ethereum, expanding later to Solana and Ethereum Layer 2 platforms.
Similarly, major institutional players, including JPMorgan, have issued tokenized money-market funds on Ethereum, allowing subscriptions in cash or USDC and leveraging the regulatory advantages ushered in by stablecoin-focused legislation.
These moves suggest that institutional finance increasingly views Ethereum as the settlement fabric for collateralized digital assets, tokenized cash equivalents, and secure yield-bearing instruments.
Challenges and Risks Ahead
Despite the promising outlook, BlackRock’s report underscores certain risks. In emerging markets, increasing stablecoin adoption could challenge national monetary control, potentially triggering restrictive regulatory pushback in regions where stablecoins might offer significant benefits for financial inclusion.
Market risks also remain. Not all stablecoins are created equal; trust and issuer credibility are crucial. For instance, S&P Global Ratings downgraded its assessment of Tether’s reserve quality in November 2025, highlighting ongoing concerns about stablecoin backing and market structure integrity.
Conclusion
BlackRock’s 2026 Global Outlook paints a transformative picture for crypto markets — stablecoins are no longer peripheral but are becoming central to the future of payments and settlement. As the industry evolves, Ethereum has emerged as the dominant blockchain anchoring the settlement layer, supported by its unmatched security, governance, and growing institutional ecosystem.
With regulatory frameworks evolving and institutional adoption accelerating, the crypto settlement landscape is entering a new era marked by consolidation and maturation, with Ethereum at the helm of this historic shift.
