BlackRock’s 2026 Outlook: Stablecoins, Ethereum, and the Battle for Crypto’s Settlement Layer

BlackRock’s latest Global Outlook doesn’t treat stablecoins as a speculative side show. Instead, the firm frames them as emerging financial rails that are beginning to sit alongside – and in some cases inside – the existing payments and settlement stack. That shift has direct implications for which blockchains accrue value as the underlying settlement fabric, with Ethereum increasingly positioned as the default institutional anchor.

How BlackRock Reframes Stablecoins

In its 2026 Global Outlook, the BlackRock Investment Institute argues that stablecoins are moving beyond their origin as a crypto-native convenience and are becoming embedded in mainstream payment systems. The report points to three trajectories in particular:

• Integration into established payment networks
• Use in cross-border transfers where legacy rails are slow and costly
• Day-to-day transactions in emerging markets

That framing matters for market structure because it shifts the investor question from “are stablecoins good for crypto trading?” to “are stablecoins becoming a settlement rail that coexists with traditional finance?”

Samara Cohen, BlackRock’s global head of market development, encapsulates the thesis in a line the report highlights: stablecoins are “no longer niche” and are “becoming the bridge between traditional finance and digital liquidity.” For crypto investors, that language signals BlackRock views stablecoins less as an asset class and more as infrastructure.

Once stablecoins are treated as infrastructure, the next-order question becomes which chains actually matter when the system settles, not just where the cheapest or fastest transfers occur. That is where Ethereum’s role comes into focus.

From Trading Chip to Payments Rail

Stablecoins initially grew by solving a tactical problem inside crypto markets. Volatility was high, exchanges operated 24/7, and fiat banking rails remained constrained by business hours, weekends, and jurisdictional frictions. Dollar-pegged tokens offered traders a way to hold a quasi-dollar on-exchange, enabling instant movement between assets without touching bank wires.

BlackRock’s analysis suggests that phase is effectively over. Stablecoins are now large and mature enough that their next use cases naturally extend into mainstream payments and settlement, especially where:

• Banks and correspondent networks introduce latency and cut-off times
• Fees remain high for remittances and cross-border corporate flows
• Local infrastructure in emerging markets is underdeveloped

The regulatory backdrop is an important enabler in BlackRock’s view. In the US, the GENIUS Act, signed into law on July 18, 2025, created a federal framework for payment stablecoins, including rules on reserves and disclosures. That kind of statute does not guarantee mass adoption, but it substantially alters the risk calculus for banks, payment processors, and large merchants who must answer to compliance and regulators.

Scale is no longer hypothetical. As of Jan. 5, 2026, total stablecoin value was about $298 billion, with USDT and USDC still dominating. BlackRock, drawing on CoinGecko data through Nov. 27, 2025, notes that stablecoin market caps reached record highs even as broader crypto prices fluctuated. The report positions stablecoins as the core source of “dollar liquidity and on-chain stability” for the ecosystem.

This combination of legal recognition and size is pushing stablecoins into areas of finance that are usually invisible – namely, the back-office settlement layer. In December 2025, Visa provided a concrete example by announcing USDC settlement in the United States. Selected issuer and acquirer partners can now settle with Visa in Circle’s dollar stablecoin, with initial implementations running over Solana. Visa framed this as a modernization of its settlement layer, enabling faster fund movement and seven-day availability, including weekends and holidays.

For practitioners, the message is that stablecoins are no longer only a front-end trading tool; they are being tested as back-end plumbing.

Why the Settlement Layer Is Where Value Accrues

Once stablecoins function as digital dollars at scale, the location of final settlement becomes the key strategic battleground. BlackRock’s outlook connects stablecoin growth to more complex use cases: collateral, treasury management, tokenized money-market funds, and cross-border netting. In those scenarios, the base chain must provide:

• Predictable economic and technical finality
• Deep liquidity and broad counterparty support
• Mature tooling, custody, and compliance integrations
• A governance and security model credible over decades, not market cycles

This is where Ethereum enters the narrative. Its competitive edge in 2026 is not being the cheapest chain for a single stablecoin transfer—high-throughput chains like Solana clearly have relevance there, as Visa’s pilot demonstrates. Instead, Ethereum has become the anchor for an ecosystem that treats execution and settlement as distinct layers.

Ethereum’s own documentation around rollups makes that role explicit: Layer-2 networks handle high-volume execution, while Ethereum mainnet functions as the settlement layer that anchors security and provides objective finality for disputes. In practice, this means:

• Users transact rapidly and cheaply on L2s or alternative environments.
• High-value state – including collateral positions and tokenized assets – ultimately settles back to Ethereum.

For investors, the implication is that value tends to concentrate where final settlement and dispute resolution occur, not necessarily where raw throughput is highest. The more economically significant the activity that ultimately settles on a chain, the greater the potential value accrual to that chain’s native asset and ecosystem.

Tokenization Is Steering Institutions Toward Ethereum

BlackRock’s discussion of stablecoins explicitly links them to tokenization. The firm characterizes stablecoins as a “modest but meaningful step toward a tokenized financial system” in which digital dollars coexist with and reshape traditional intermediation and policy channels.

Tokenization makes that idea concrete: a real-world asset such as a Treasury bill fund is represented as a blockchain token. Stablecoins become the cash leg for subscriptions, redemptions, and secondary market trading of those tokenized claims.

On this front, Ethereum is currently the primary venue. Data from RWA.xyz, cited as of Jan. 5, 2026, shows roughly $12.5 billion in tokenized real-world assets on Ethereum, representing about 65% market share. That concentration reflects where institutions have found the deepest liquidity, the most mature custody and compliance stacks, and the most battle-tested smart contract standards.

BlackRock itself has contributed to Ethereum’s gravitational pull. Its tokenized money-market fund, BUIDL, launched on Ethereum and later expanded to multiple chains, including Solana and several Ethereum Layer 2s. Tokenized Treasuries have become one of the clearest real-world use cases for on-chain finance, and the pattern BlackRock followed is illustrative:

• Start on the chain with the most developed institutional infrastructure (Ethereum).
• Then extend distribution to other networks as they mature and as client demand warrants.

JPMorgan has moved along a similar path. The bank launched a tokenized money-market fund with shares represented as digital tokens on Ethereum, accepting subscriptions in cash or USDC. The initiative was tied, in part, to the regulatory clarity around stablecoins following the GENIUS Act.

Taken together, these examples suggest that for institutional-grade tokenization and collateralization, stablecoins need more than fast payments. They require a settlement fabric that can reliably host large tokenized portfolios, integrate with existing financial plumbing, and support long-term risk management. Today, Ethereum is the default answer to that requirement, not because it wins every technical benchmark, but because it is perceived as the settlement “court” where the most valuable cases are heard.

Risks and Constraints: Policy, Issuers, and Multi-Chain Reality

BlackRock’s outlook is not uncritical. It flags several areas of risk and friction that could shape how the settlement race plays out.

First, in emerging markets, wider use of dollar-linked stablecoins could erode domestic currency usage and complicate monetary policy. That is a political-economy issue rather than a technical limitation, but it is precisely the kind of concern that can elicit restrictive regulatory responses in jurisdictions where stablecoins have strong product-market fit.

Second, issuer risk remains central. Stablecoins differ sharply in governance, transparency, and reserve composition. In November 2025, S&P Global Ratings downgraded its assessment of Tether’s reserves, citing transparency concerns. The episode underscored that the stability of on-chain “dollars” ultimately depends on what sits behind the peg and how clearly those reserves are disclosed.

Third, Ethereum’s dominance as a settlement layer is not guaranteed. Visa’s USDC settlement work, conducted over Solana in its initial US rollout, illustrates that large incumbents will choose alternative chains when they fit operational requirements. Circle, for its part, positions USDC as a natively multi-chain stablecoin supported across dozens of networks. That strategy intentionally makes liquidity portable and reduces dependence on any single chain.

However, this portability cuts both ways. As stablecoins spread across environments, the strategic premium moves to the layers that can offer:

• Credible, legally and technically robust settlement
• Tight integration with tokenized real-world assets
• Security and governance credible enough for institutions to park real cash and collateral on-chain over long horizons

Within that multi-chain context, Ethereum still looks like the leading candidate for the settlement standard of tokenized dollars. The chain may not host every transaction, but it is increasingly the environment where high-value claims and disputes are ultimately resolved.

What This Means for Crypto Investors and Market Structure

For crypto investors and digital asset professionals, BlackRock’s outlook reframes several core theses:

• Stablecoins as infrastructure, not just instruments: Their role is shifting from trading chips to foundational rails that connect traditional and digital markets.
• Settlement as the value locus: The chains that anchor final settlement for stablecoins and tokenized assets, rather than those that simply process cheap transfers, are likely to capture a disproportionate share of value.
• Ethereum as current settlement bedrock: Institutional tokenization flows, regulatory-aligned stablecoin use, and rollup-centric architecture all reinforce Ethereum’s role as the main settlement layer, even as execution fragments across L2s and alternative L1s.
• Policy and issuer risk as key variables: Monetary sovereignty concerns, regulatory responses, and the credibility of stablecoin issuers can still reshape how – and where – stablecoin rails develop.

BlackRock portrays stablecoins as a bridge between traditional finance and digital liquidity. Bridges, however, are only as reliable as the foundations they rest on. In the current architecture of the crypto market, Ethereum is the bedrock institutions keep returning to for settlement, collateral, and tokenized cash – even as the broader ecosystem remains unmistakably multi-chain.
