BlackRock adds tokenized share classes to European money market funds holding $311bn

What was announced

BlackRock on August 4, 2026 launched Ethereum-based tokenized share classes for selected funds in its Institutional Cash Series, a money market range with a combined $311 billion under management, made available across 15 European markets including the UK, Germany and France.

The share classes come in sterling, euro and dollar denominations and are structured to comply with UCITS rules — the European fund framework that governs what can be sold to retail and institutional investors across the bloc. The onchain infrastructure was developed with Kinexys, JPMorgan's blockchain platform.

It is the second announcement in two days. On August 3, BlackRock extended the same idea in the United States with onchain shares of the BlackRock Select Treasury Based Liquidity Fund and a vehicle described as a Daily Reinvestment Stablecoin Reserve Vehicle.

Reading the $311bn figure

The $311 billion is the assets under management of the underlying funds, not the value of tokens issued against them. A tokenized share class is a wrapper: the same fund, recorded on a blockchain rather than only in a transfer agent's ledger. How much of that $311 billion ends up represented onchain is a separate question, and nothing in the announcement quantifies it.

For scale, the tokenized real-world asset market has grown more than 200% over the past year to above $30 billion. That total is roughly a tenth of the AUM in the European funds now carrying a token wrapper — which is why the headline number and the market-size number should not be compared directly.

The reason this segment matters to anyone trading crypto or prediction markets is collateral. Tokenized money market shares can, in principle, move between counterparties on the same rails as stablecoins while still paying a yield, which is the pitch behind both the UCITS classes and the US stablecoin reserve vehicle. Whether venues actually accept them as margin is the test that follows.

Caveat

The details above come from a search summary of the launch. None of the sources credited below carries the announcement, so the specifics — market count, share class currencies and the Kinexys involvement — warrant checking against BlackRock's own disclosure before they are treated as settled.
