Wall Street Is Building Digital Asset Infrastructure

Four Banks, One Direction

The scale and specificity of recent announcements distinguishes this moment from prior cycles of institutional interest in digital assets.

Morgan Stanley submitted a formal application to the OCC on February 18, 2026 for a national trust bank charter for digital asset custody. The proposed entity, Morgan Stanley Digital Trust, would offer custody, trading, and staking services across the bank's $8 to $9 trillion client base. The bank is also planning direct digital asset trading on E*Trade in the first half of 2026. Morgan Stanley is building wallet technology in-house rather than outsourcing. As Amy Golenberg, the bank's head of digital assets, stated: "We need to build this internally. We can't just rent the technology."

JPMorgan's Kinexys platform, a blockchain-based settlement network, has processed over $3 trillion in cumulative transaction volume, averaging $5 billion daily. JPM Coin, the bank's tokenized deposit product, is being issued on the Canton Network with a phased rollout through 2026. The bank plans to accept Bitcoin and Ethereum as loan collateral.

Citigroup is targeting a digital asset custody launch later in 2026, building a single master safekeeping account that combines digital assets, securities, and cash with cross-margining between asset classes. Citi Token Services, a 24/7 blockchain-based network for internal cross-border money movement, is already operational.

Barclays invested in Ubyx, a stablecoin clearing startup, in January 2026 and is building a blockchain payment platform with supplier selection expected by April.

The common thread is not experimentation. It is infrastructure buildout. These are custody solutions, settlement networks, and trading platforms designed for institutional scale.

Why Now: The Regulatory Reversal

Eighteen months ago, these same institutions faced systematic regulatory discouragement. A November 2025 House Financial Services Committee report documented the extent: the FDIC had sent letters to 25 banks advising them to "pause" digital asset activities. Thirty entities and individuals were documented as debanked. The SEC's Staff Accounting Bulletin 121 (SAB 121) required custodians to record digital assets as balance-sheet liabilities, effectively making custody uneconomical for banks.

The reversal has been swift and comprehensive. SAB 121 was rescinded in January 2025. The OCC granted conditional trust charters to five digital asset firms in December 2025 and retired "reputation risk" as a supervisory lever. The GENIUS Act, signed into law on July 18, 2025, established the first federal regulatory framework for stablecoins: one-to-one reserve backing, federal oversight, and priority claims for holders in insolvency. SEC Chair Paul Atkins launched a joint "Project Crypto" initiative with the CFTC to bring coordinated oversight to digital asset markets.

For the first time, banks have a regulatory framework that makes digital asset custody and settlement economically viable. They are responding accordingly.

The Infrastructure They Are Building On

The bank buildout is happening on top of two infrastructure layers that matured over the past twelve months: tokenized funds and stablecoin payment rails.

Tokenized money market funds now hold over $9 billion in U.S. Treasuries, nearly tripling from $3.9 billion earlier in 2025. BlackRock's BUIDL fund, a tokenized money market fund where each token represents $1 backed by short-term Treasuries, grew to $2.85 billion and was listed on Uniswap, the largest decentralized exchange, in February 2026. Franklin Templeton's BENJI fund holds over $800 million across seven blockchain networks. These are not speculative instruments. They are cash-equivalent holdings that settle around the clock without waiting for wires, cutoffs, or business-day constraints.

The more important development is how these instruments are being used. BUIDL is now accepted as trading collateral. Franklin Templeton has modified its money market funds to meet stablecoin reserve standards. Tokenized Treasury holdings are being deployed as building blocks within the broader digital asset settlement infrastructure.

Stablecoin payment volume reached $9 trillion in the twelve months ending September 2025, up 87% year-over-year. The companies processing these payments include Stripe, which acquired stablecoin infrastructure company Bridge for $1.1 billion and now supports stablecoin payments in 101 countries. Visa launched USDC settlement in the United States in December 2025, settling over the Solana network seven days a week. A Fireblocks survey found that 49% of 295 financial institutions were already using stablecoins, with another 41% in pilot or planning stages.

Stablecoins (digital tokens designed to maintain a 1:1 peg with the U.S. dollar) function as a payment rail, not a speculative asset. A cross-border wire takes three to five business days and involves intermediary banks with compounding fees. A stablecoin transfer settles in minutes at a fraction of the cost.

What Has Not Changed

Better settlement infrastructure does not eliminate risk. It changes its shape.

Tokenized funds settle faster than their traditional equivalents, but the smart contracts executing those settlements introduce a category of operational risk that does not exist in legacy infrastructure. Stablecoin payments clear in minutes, but if the issuer's reserves are opaque or the redemption mechanism fails under stress, speed becomes a liability.

The stablecoin yield debate illustrates a structural tension that remains unresolved. The OCC's proposed GENIUS Act rules explicitly prohibit stablecoin issuers from paying interest or yield to holders. Over 40 banking associations lobbied for this provision, arguing that yield-bearing stablecoins could drain bank deposits. Whether stablecoins are permitted to pay yield will determine whether they remain a payment rail or become a direct competitor to the banking system.

And the accounting, tax, and compliance infrastructure for digital asset operations remains immature. The tools are improving, but the risk management frameworks are still catching up to the technology.
