A new Citi report released June 1, 2026 — shared exclusively with CoinDesk ahead of Proof of Talk in Paris — puts a headline number on the tokenization trade: $5.5 trillion in tokenized securities by 2030, up from $17 billion today.

The base case sits at $5.5 trillion. Under a bear scenario, adoption stalls at $2.7 trillion; a bull run gets to $8.2 trillion. The report, titled Tokenization 2030: Wall Street On-Chain, is Citi's most direct statement yet on when and how mainstream capital markets move on-chain — and it names the specific institutions doing the work.

"You're seeing the full weight of American financial power and the global reserve currency moving on chain at scale," the report states. "When DTCC and the NYSE embed tokenization into capital markets, this marks a tipping point."

Three drivers

Citi identifies three structural shifts making this forecast credible rather than aspirational.

Traditional market infrastructure is building the rails. The Depository Trust & Clearing Corporation — the entity that settles the vast majority of U.S. securities trades — announced in early May that it would begin limited production trading of tokenized securities in July 2026, with a broader platform launch in October. Nasdaq received SEC approval to allow certain stocks to be issued and traded in digital on-chain form and is working on a framework for blockchain-based share issuance with a potential launch as early as 2027. Intercontinental Exchange, owner of the New York Stock Exchange, is in a strategic partnership with crypto exchange OKX targeting tokenized stocks. These are not pilot programs or proof-of-concepts. They are production timelines from the organizations that run the plumbing of U.S. equity markets.

Trusted digital cash closes the settlement gap. Stablecoins are projected to reach a $1.9 trillion market cap by 2030. The Citi report treats this not as a crypto story but as a financial infrastructure story: stablecoin issuers back their tokens with real assets, and Citi forecasts this growth alone will generate roughly $1 trillion in new demand for U.S. Treasury bills as reserves. Stablecoins working alongside digital bank deposits create the other side of the trade — assets and cash that can settle simultaneously, on-chain, at the moment of exchange. That simultaneous settlement has been the missing operational piece in prior tokenization attempts.

Regulatory clarity is arriving. On May 14, 2026, the Senate Banking Committee cleared the Clarity Act 15-9 in a bipartisan vote, ending a four-month stall and sending the bill to a full Senate vote. The Citi report cites this as the third structural driver — not a promise of clarity, but an actual procedural advance toward the legal framework that lets institutional capital move into tokenized instruments without ambiguity about what it owns.

Where the growth lands

Citi is deliberate about scope. The report's forecast concentrates on mainstream public markets — U.S. Treasuries and publicly traded equities — not private credit or private equity. The distinction matters because those two categories often dominate tokenization projections from firms looking to sell into illiquid asset digitization.

Citi's assumptions are transparent: 10% of the U.S. Treasury bill market and 3% of the U.S. public stock market tokenized by 2030. If 10% of retail U.S. investors move to digital trading platforms, that alone creates $2.6 trillion in demand for tokenized equities. Private credit and private equity each cap at $100 billion globally by 2030 — a notably modest estimate that reflects how slowly those markets change hands and how complex their legal structures remain.

The read is structural, not promotional: the growth happens where the assets are liquid, the infrastructure is already owned by regulated entities, and the investor base is large enough to move the numbers.

The transition model

Citi frames the shift using an analog: E-ZPass highway toll adoption. Electronic tolling did not eliminate cash lanes overnight. States built wider roads with parallel lanes running both systems simultaneously — adding cost and complexity in the middle period before full conversion. The same overlap is coming for capital markets. Old clearing infrastructure and new tokenized rails will run side by side for years.

The report names "Structural Orchestrators" as the winners in this middle period: large banks and investment firms that control both the real assets and the digital cash rails used to settle them. Firms that can handle the full trade inside their own network capture the spread from both sides. That framing points to who Citi sees benefiting most from the buildout — not crypto-native firms, but the institutions already at the center of capital markets.

The report lands at a moment when the infrastructure pieces it describes are already in motion. DTCC has a July date. Nasdaq has SEC approval. The Clarity Act has a floor vote coming. Citi's $5.5 trillion number is not a prediction about technology maturing — it is a forecast about known institutions executing against publicly announced timelines.
