JPMorgan: Private Blockchains Could Reroute $4.7T

JPMorgan warned that shifting tokenization, payments and settlement onto bank-run private blockchains could siphon activity, liquidity and capital away from public crypto networks and fee markets.

The bank described private, permissioned ledgers run by banks, custodians and market infrastructure providers as capable of routing tokenized deposits and securities through closed systems that do not rely on public-chain settlement. Swift has begun tests with 17 banks, including Citi, HSBC, Standard Chartered, UBS, Wells Fargo and Itaú Unibanco, to trial live tokenized deposit payments on a new blockchain ledger designed for round-the-clock transfers. The Depository Trust & Clearing Corporation reported more than 50 firms, including BlackRock, Goldman Sachs, Morgan Stanley, Nasdaq and the NYSE, joined its tokenization working group; limited production trades are planned for July 2026 and a full launch is scheduled for October 2026.

The scale of existing market infrastructure is large. The Depository Trust Company custodizes over $114 trillion in assets and DTCC subsidiaries processed about $4.7 quadrillion in securities transactions in 2025. JPMorgan noted that if tokenized deposits and securities settle inside bank-controlled ledgers or DTC/DTCC systems, those flows might not touch public blockchains, stablecoin rails or decentralized finance platforms that currently capture settlement-layer fees and liquidity.

Research and forecasts quantify the potential market. Citi’s Tokenization 2030 report projects a tokenized asset market ranging from $2.7 trillion to $8.2 trillion by 2030, with a base case of $5.5 trillion. The Bank for International Settlements has observed that private permissioned networks can meet regulatory and governance requirements while presenting a risk of creating closed ecosystems that limit competition.

JPMorgan outlined three possible outcomes. One scenario sees tokenization scale inside gated, reversible rails controlled by banks and intermediaries, reducing demand for public-chain settlement services. A second scenario treats private-rail adoption as the capture of the infrastructure opportunity, with ETFs and liquidity shifting away from public-chain crypto. A third scenario has both systems operating side by side: banks using permissioned ledgers for settlement while public chains retain some utility.

Context on market behavior and risk metrics was provided. Spot Bitcoin ETFs offer custody-wrapped exposure to Bitcoin; BlackRock’s IBIT held about $45.6 billion in net assets as of July 8 despite a year-to-date net asset value return near -29%. JPMorgan reported that Bitcoin’s price history has shown higher volatility than global equities, roughly four times greater over the past decade, and estimated that a 5% allocation to Bitcoin added 13% to portfolio risk compared with 2% for a similar gold allocation.

Public-chain payments remain concentrated in stablecoins, with an aggregate market capitalization near $312 billion. Tokenized U.S. Treasuries are near $15 billion compared with a roughly $30 trillion Treasury market. Some crypto firms are developing technical defenses against potential future threats from quantum computing.

JPMorgan framed the development as a competition between closed, regulated rails and open public networks. The eventual impact on public-chain fees, liquidity and token values will depend on investor flows, macro liquidity conditions and how broadly tokenization is adopted on permissioned ledgers versus public chains.
