Forget the easy crypto-fad take. BlackRock (NYSE: BLK) just filed not one but two new tokenised fund products on Friday — a $7bn (~£5.1bn) Treasury liquidity fund moving onchain, plus a brand-new stablecoin reserve vehicle. The world’s biggest asset manager is voting with paperwork. The tokenised finance sector that just crossed $30bn (~£22.0bn) for the first time has its institutional anchor.
The $7bn number that just moved onchain
The Friday SEC filing outlines how BNY Mellon Investment Servicing, the fund’s transfer agent, will maintain official ownership records on Ethereum using ERC-20 token standards.
BlackRock’s Select Treasury Based Liquidity Fund — a traditional money-market fund with nearly $7bn (~£5.1bn) in assets under management — is getting an onchain share class. The Friday SEC filing outlines how BNY Mellon Investment Servicing, the fund’s transfer agent, will maintain official ownership records on Ethereum using ERC-20 token standards.
Translation: the same investors who own this fund today will, if the SEC clears the filing, see their ownership tracked on a public blockchain rather than a private back-office database. The fund itself stays a money-market fund. The recordkeeping plumbing just shifts onto Ethereum’s rails.
That’s not a token launch. It’s not a crypto pivot. It’s the world’s biggest asset manager rewiring the back-office of a $7bn (~£5.1bn) Treasury product to run on a public blockchain. The signal matters more than the mechanics — when BlackRock files paperwork like this, every traditional asset manager’s board reviews the same option fast.
The second filing nobody is talking about
The second SEC filing is the BlackRock Daily Reinvestment Stablecoin Reserve Vehicle — a brand-new fund that invests in cash, short-term US Treasury securities, and overnight repurchase agreements backed by Treasuries.
That product profile matters. It’s almost identical to what stablecoin issuers hold as reserves. Tether and Circle’s USDC are both backed primarily by short-term Treasuries and cash equivalents. BlackRock just filed a regulated fund product purpose-built to sit alongside — or underneath — that infrastructure.
If the SEC clears it, BlackRock is positioned to siphon the institutional back-end of the entire stablecoin economy. That’s a far bigger structural play than launching a tokenized fund — capturing reserve management for the stablecoin sector at BlackRock fee structures generates meaningful annual revenue from a single SEC approval, and binds stablecoin issuers’ fortunes to BlackRock’s regulated wrapper for years.
From BUIDL to today: BlackRock’s two-year arc
BlackRock’s tokenisation push isn’t new. In March 2024 it launched BUIDL — its first tokenised money-market fund — with Securitize as the tokenisation partner. BUIDL grew quickly, and BlackRock CEO Larry Fink has repeatedly framed tokenisation as the modernisation of financial infrastructure, not a crypto sideline.
The Friday filings are the next two products in that arc. Same partner (Securitize). Same chain (Ethereum). Higher AUM at risk ($7bn (~£5.1bn) versus BUIDL’s smaller starting base). And a new category — the stablecoin reserve vehicle — that didn’t exist in BlackRock’s playbook before this week.
The pattern smashes the experimental-tokenisation narrative. BlackRock’s $14tn (~£10.3tn) under management isn’t being deployed via headline-grabbing Bitcoin announcements. It’s being deployed via SEC paperwork that quietly rewires the rails of existing flagship products. Same playbook Larry Fink ran for ETFs in the 2010s, now applied to onchain finance.
What this means for UK retail investors
Tokenised finance as a sector has crossed $30bn (~£22.0bn) this year. That growth happened with niche crypto-native firms doing most of the heavy lifting. BlackRock filing two new products at $7bn (~£5.1bn)-plus scale flipped the centre of gravity decisively toward traditional asset managers.
UK retail investors should expect two structural shifts to follow. First, abrdn (LON: ABDN), M&G, and Legal & General (LON: LGEN) will face board pressure to file their own tokenised share classes — likely within 12 months. Each will struggle to justify NOT having an onchain product when BlackRock has set the standard.
Second, existing UK-listed ETF wrappers tracking BlackRock’s BUIDL-adjacent products will see fresh inflows as the institutional thesis hardens from theoretical to filed. Retail flows tend to chase institutional signals on a six-to-nine-month lag — and the institutional signal just got filed, in writing, with the SEC.
The fad story is dead. The tokenisation sector is becoming infrastructure — and UK asset managers caught flat-footed will spend the rest of 2026 catching up.
The Bottom Line
Watch for the next BlackRock filing. If the BUIDL trajectory holds, by year-end 2026 we’ll see brand-name UK asset managers filing their own tokenised products. The institutional infrastructure for crypto-native finance is being built quietly, one SEC filing at a time. You’re either positioning for it or you’re already late.

FAQ
What is BlackRock’s BUIDL fund?
BUIDL is BlackRock’s first tokenised money-market fund, launched in March 2024 with Securitize as partner. It records ownership on the Ethereum blockchain using ERC-20 token standards — the same approach now proposed for the $7bn (~£5.1bn) Select Treasury Based Liquidity Fund.
Does the onchain share class change how the fund works?
No — the underlying fund stays a regulated money-market fund holding Treasuries and cash; only the ownership-record plumbing moves from BNY Mellon’s private database to the public Ethereum ledger. Investors get blockchain transparency without the product itself changing.
Why does BlackRock care about stablecoin reserves?
Stablecoin issuers like Tether and Circle hold billions in short-term Treasuries to back their tokens. A regulated BlackRock fund purpose-built for that reserve profile positions BlackRock to capture the institutional back-end of the entire stablecoin economy — bigger than any single tokenised fund product.
