Wall Street’s biggest balance sheets are quietly rebuilding the crypto stack under the banner of tokenization and custody.
What began as a defensive stance toward digital assets is turning into an infrastructure shift: bringing fund administration, cash management, and settlement onto blockchain rails that look more like BNY Mellon’s LiquidityDirect platform than a typical crypto exchange.
Money market funds are among the safest and most liquid investment vehicles in traditional finance. They hold short-term government and corporate debt, giving institutions a way to park cash while earning modest yields with minimal risk. Tokenizing them turns those holdings into digital units that can be transferred instantly and settled 24 hours a day.
For large institutions, the benefit is not speculative but operational: corporate treasurers can move cash faster, pledge assets as collateral, and reduce the frictions that come with banking cut-off times.
The structure resembles traditional custody, but settlement happens atomically, meaning payment and asset transfer occur simultaneously without intermediaries.
As tokenized cash and securities become mainstream, these percentages start to resemble the fees charged in fund administration and collateral management, creating an overlap that did not exist before.
In this version of tokenization, the appeal is not headline innovation but efficiency. A tokenized Treasury or fund share can move instantly between accounts and settle in real time, cutting costs for both clients and custodians. The conservative outlook for this market sees tokenized Treasuries hovering between $6 billion and $8 billion if regulation slows and yields fall.
A middle-ground projection expects around $10-15 billion by mid-2026 as more banks integrate money-market products. The optimistic scenario reaches $25-40 billion if tokenized cash accounts tied to ETFs take off and if banks start testing repo markets for tokenized collateral.
Repos are the backbone of short-term lending in finance. Banks lend cash in exchange for safe collateral such as Treasuries, agreeing to reverse the trade later. Tokenized repos would allow these transactions to settle automatically on a blockchain, reducing the operational delays and counterparty risk that currently require expensive intermediaries.
That collateral link is what turns tokenization from a bookkeeping experiment into real financial plumbing. Goldman and BNY’s tokenized money-market shares already move within closed, permissioned environments.
If the project succeeds, 2026 could bring the first bank-to-bank repo transactions executed entirely with tokenized assets.
Today’s systems still operate inside walled gardens. Networks such as Goldman’s GS DAP, SDX, and JPMorgan’s Onyx offer efficiency at the cost of interoperability. Regulators prefer this model because every participant is known and verified, but financial institutions are beginning to explore how permissioned systems might connect to public networks through cryptographic proofs that preserve compliance.
If that link is established, custody fees could expand toward $300–600 million in annual revenue, assuming tokenized cash and Treasury products reach $25–40 billion in assets and charge service fees near 0.1–0.15%.
The UK and Singapore are building similar frameworks through Project Guardian to standardize tokenization in asset and wealth management.
Money-market tokens may sound like plumbing, but plumbing determines who controls the flow of funds. In this race, the flow is not just digital assets but the future structure of the balance sheet itself.
