Aviva tokenizes its £22 billion sterling fund as US, EU regulators eye the plumbing

Aviva Investors has added a blockchain-recorded share class to its largest money market fund, the latest sign that tokenized cash products are moving into mainstream asset management. The launch lands days after the SEC and ESMA both put tokenization on their supervisory agendas.

Aviva Investors on Monday opened a tokenized share class of its Sterling Liquidity Fund, a money market fund of about £22 billion, on the XRP Ledger. The British asset manager put £50 million of its own money into the new class. The move comes in a month when regulators on both sides of the Atlantic have started asking harder questions about how tokenized assets behave inside the financial system, rather than whether they should exist at all.

What happened

The Sterling Liquidity Fund is the firm's largest fund. It was set up in 2002 as an Irish-domiciled UCITS money market fund that buys short-term, high-quality debt denominated in pounds and lets investors in and out daily. Under the structure Aviva chose, the fund keeps running in the conventional way, while the new share class records each investor's holding on a public blockchain. Industry participants call this a "digital twin" model. Investors need an eligible digital wallet to hold the shares.

Aviva says the tokenized shares carry the same investment objective, risk profile, liquidity terms and regulatory protections as the existing classes. BNY Mellon remains the custodian of the fund's underlying assets. Ripple worked with Aviva on the launch, with support from digital asset custodian Komainu and tokenization platform Licuido, according to The Block and crypto.news.

The sterling class follows a tokenized share class of Aviva's U.S. Dollar Liquidity Fund, launched on the same ledger on July 29 after approval from the Central Bank of Ireland. Across the two, Aviva has now committed more than £86 million of its own capital. The partnership with Ripple was first announced in February, when Ripple described Aviva as its first European investment management partner. Aviva chief executive Mark Versey said, "We believe tokenized funds can increase efficiency and ultimately lead to improved client outcomes." He added that the firm plans to look for further projects with Ripple.

The size of the onchain slice is still small. Aviva's £50 million seed is roughly 0.2% of the fund's total assets, and neither report disclosed how many outside investors have signed up. The launch adds a large European name to a field already populated by U.S. managers. BlackRock's BUIDL fund, Franklin Templeton's Benji platform and JPMorgan Asset Management's MONY fund all offer tokenized exposure to cash-like assets.

Regulators have been moving in parallel. On Oct. 23 the SEC's Division of Examinations published its priorities for fiscal 2027, which begins this month and covers more than 34,000 registered firms. For the first time, the list names tokenization as a high-risk area in examinations of clearing agencies, alongside default management, recovery and wind-down planning, securities lending and operations, according to Unchained and crypto.news. Exams under Regulation SCI, the SEC's rule on the resilience of core market systems, will look at tokenized securities together with extended trading hours and quantum computing. Transfer-agent reviews will cover emerging technology and the accuracy of ownership records. The document does not use the word crypto, and the SEC notes it creates no new legal obligations.

Earlier in October, the SEC proposed rules on how investment advisers and regulated funds may hold crypto assets. The plan would let state trust companies act as custodians and allow self-custody in some circumstances, with comments open for 60 days after publication in the Federal Register. In Europe, the European Securities and Markets Authority opened a call for evidence on Oct. 9 about using tokenized assets as collateral at central clearing houses. ESMA wants to know whether a clearing house could seize and sell tokenized collateral quickly if a member defaults, and whether transferring a token actually transfers enforceable rights to the underlying asset.

The debate

Supporters of tokenized money funds argue that the gains are practical rather than speculative. A fund share that lives on a ledger can, in principle, move between wallets at any hour and settle almost instantly. That makes it easier to use as collateral or to swap into a stablecoin without waiting for bank hours. For asset managers, it is also a way to keep cash from crypto-native firms and trading desks inside regulated funds instead of losing it to stablecoins that pay holders no yield.

Skeptics point out that the digital twin approach leaves most of the old machinery in place. The fund's assets, valuation and dealing still run through traditional administrators and custodians, so the blockchain mainly serves as a second ownership register. Critics say that limits the efficiency gains until settlement itself moves onchain. They also note that much of the money in early tokenized funds has come from the sponsors themselves, which makes it hard to judge real client demand.

The regulators' questions sit between these camps. Neither the SEC nor ESMA is trying to stop tokenization. Their concern is what happens under stress. If a tokenized share and the underlying fund record disagree, which one wins? If a clearing member fails, can its tokenized collateral be sold as fast as a Treasury bill? And how do firms manage outages at the blockchain networks or outside vendors they now depend on? Those are the issues the SEC's exam list and ESMA's call for evidence flag directly.

A separate fight over tokenized equities shows how sensitive ownership can become. Under an SEC exemption issued in September, blockchain venues that want to list tokens tracking U.S. stocks must first notify the companies involved, which then have 30 days to object. Several issuers, including Broadcom and Verizon, have used that window to block their shares from the planned OKX and Intercontinental Exchange joint venture, citing possible investor confusion and effects on liquidity. Money market funds raise fewer of these issues, because the manager issues its own tokens. But the episode shows that who controls the token can matter as much as the technology underneath it.

What it means

For investors in Europe, the Aviva launch suggests UCITS money market funds can carry tokenized share classes without a new legal regime, using Ireland's existing fund rules. Investors in the U.S. and Singapore will find similar products, though often limited to qualified or institutional buyers. In each case, the tokenized share is a claim on the same conventional fund, with the same risks. It is not a stablecoin.

Several items are worth watching in the coming weeks. Ripple holds its Swell conference in New York from Oct. 27 to 29, where partners often detail new tokenization deals. The SEC's custody proposal will draw comments from banks, trust companies and crypto custodians on who can safely hold tokenized assets for funds. ESMA's findings on tokenized collateral will help decide whether the EU writes new rules or adapts existing ones. Another signal is whether outside clients, not just sponsors, start moving meaningful sums into tokenized share classes like Aviva's.

The direction of travel is clear enough. Large managers are putting their core cash products onchain, and supervisors are now focused on how those products fail, settle and change hands, rather than whether they belong in regulated markets at all.
