"Imagine if that same digital wallet could also let you invest in a broad mix of companies for the long term—as easily as sending a payment. Tokenization could help accelerate that future by updating the plumbing of the financial system." — Larry Fink, CEO, BlackRock (2026 Annual Chairman's Letter)
Tokenized money market funds (TMMFs) have grown from $770 million at the end of 2023 to approximately $9 billion in assets under management as of March 2026, according to a Bank for International Settlements bulletin published in March 2026. The 1,068% expansion in 27 months makes TMMFs the fastest-growing segment of the $12 billion tokenized real-world asset market tracked by rwa.xyz.
Three events in the final week of March 2026 alone underscore the acceleration: Invesco ($2.2 trillion AUM) assumed management of Superstate's $967 million USTB tokenized treasury fund on March 24; Franklin Templeton ($1.7 trillion AUM) partnered with Ondo Finance on March 25 to tokenize five ETFs for 24/7 blockchain trading; and the CFTC outlined an August 2026 deadline for rulemaking that would formally approve tokenized fund shares as margin collateral in derivatives markets. Each move extends the same thesis: traditional fund shares, reissued as blockchain tokens, can serve simultaneously as yield-bearing instruments and programmable settlement collateral — collapsing two functions that have operated in separate plumbing for decades.
The BIS, however, flagged material risks. Liquidity mismatches between instant token transfers and T+1 underlying asset settlement, concentrated holder bases, and stablecoin redemption interlinkages create contagion channels that did not exist in the pre-tokenized fund architecture. The question is no longer whether Wall Street will tokenize its fund complex, but whether the regulatory and operational infrastructure can absorb the pace.
The tokenized money market fund sector has followed a compounding growth curve since its inception:
| Period | Total AUM | Key Catalyst | |--------|-----------|-------------| | End of 2023 | $770M | Franklin Templeton FOBXX early mover | | March 2024 | ~$1B | BlackRock BUIDL launch on Ethereum | | Start of 2025 | $4B | Multi-issuer expansion | | November 2025 | $8.6B | BUIDL multi-chain, JPMorgan MONY launch | | March 2026 | ~$9B | Invesco entry, Ondo-Franklin ETF deal |
The broader tokenized U.S. Treasury market, which includes TMMFs and other short-duration government bond products, stands at approximately $5.8 billion on-chain as tracked by rwa.xyz, within a total tokenized RWA market of $12 billion. The distinction matters: TMMFs specifically invest in money market instruments (T-bills, repos, overnight paper), while the broader category includes longer-duration government bonds and structured products.
Growth from $4 billion to $9 billion in approximately 15 months represents a 125% increase. By contrast, the traditional U.S. money market fund industry holds approximately $6.7 trillion, according to the Investment Company Institute. Tokenized funds represent roughly 0.13% of that total — a figure that contextualizes both the opportunity and the distance remaining.
Five issuers control the majority of tokenized fund AUM as of March 2026:
| Issuer | Fund | AUM | Blockchain(s) | |--------|------|-----|---------------| | BlackRock / Securitize | BUIDL | ~$2.85B | Ethereum, Solana, Avalanche, Aptos, Arbitrum, Optimism, Polygon, BNB Chain | | Ondo Finance | OUSG + ecosystem | ~$2.7B (total platform) | Ethereum, Solana | | Superstate → Invesco | USTB | $967M | Ethereum | | Franklin Templeton | FOBXX | $671M | 8 blockchains | | JPMorgan | MONY | Seeded at $100M (Dec 2025) | Ethereum |
BlackRock's BUIDL dominates with roughly 32% market share by AUM. The fund launched in March 2024 at a $100,000 minimum investment threshold and reached $1 billion within 12 months. It currently pays approximately 4% APY via daily token-denominated dividends, generating an estimated $8.5–14 million annually in management fees for BlackRock, according to Laika Labs analysis.
Ondo Finance holds the second position with approximately $2.7 billion across its tokenized products. The platform has not yet begun collecting fees, with monetization planned for the second half of 2026 — a deliberate growth-over-revenue strategy. Franklin Templeton's FOBXX, the oldest tokenized fund (launched 2023), remains distributed across eight blockchains but has been outpaced in AUM growth by newer entrants.
The week of March 24–31, 2026, compressed several months of expected institutional activity into seven days.
March 24: Invesco acquires Superstate's USTB management. Invesco Advisers, Inc., a subsidiary of the $2.2 trillion asset manager, agreed to become investment manager of Superstate's $967 million USTB fund. The fund will be renamed "Invesco Short Duration US Government Securities Fund" upon transition completion in Q2 2026, while retaining its existing smart contracts, token address, and USTB ticker. Invesco's Global Liquidity team — with 45 years of cash management experience — will manage the portfolio. According to Robert Leshner, Superstate founder: "When Invesco enters the picture, it's going to expand the types of investors that are interested in this kind of product." Invesco becomes the first asset manager to use Superstate's digital transfer agent infrastructure.
March 25: Franklin Templeton tokenizes five ETFs via Ondo Finance. Franklin Templeton partnered with Ondo Finance to issue blockchain-based tokens representing the economic exposure of five ETFs: Franklin Focused Growth ETF, Franklin U.S. Large Cap Multifactor Index ETF, Franklin Responsibly Sourced Gold ETF, Franklin High Yield Corporate ETF, and Franklin Income Equity Focus ETF. The products will trade 24/7 through crypto wallets, initially available in Europe, Asia-Pacific, the Middle East, and Latin America. U.S. availability depends on further regulatory clarity. Ondo controls roughly 70% of the tokenized equity market, which stands at approximately $950 million.
Ongoing: CFTC August 2026 rulemaking deadline. Acting CFTC Chairman Caroline Pham outlined a timeline for technical amendments to margin, collateral, clearing, settlement, and reporting regulations to formally accommodate tokenized assets, with completion targeted by August 2026. The rulemaking extends guidance issued in December 2025, which established that tokenized versions of currently eligible margin assets — including U.S. Treasury securities and money market fund shares — can be used as regulatory margin, provided they satisfy existing requirements.
The economic logic driving institutional adoption of tokenized funds is not primarily about distribution efficiency or 24/7 trading. It is about collateral optimization.
In traditional derivatives markets, institutions post margin collateral in the form of cash or government securities. That collateral sits idle during settlement windows. Tokenized fund shares offer a structural advantage: they continue to earn yield (via the underlying money market instruments) while simultaneously serving as posted collateral. This dual-use function — yield generation plus settlement utility — is what the American Bankers Association terms "the key benefit of tokenized deposits" in its March 2026 analysis.
Carlos Domingo, CEO of Securitize (BlackRock's tokenization partner), framed it: "DeFi needs institutional adoption to grow, and institutions need high-quality collateral."
The implications are measurable. In derivatives markets, where the Bank for International Settlements estimates notional outstanding exceeds $700 trillion, even marginal improvements in collateral efficiency compound. If tokenized fund shares reduce capital lockup by enabling continuous yield accrual on posted margin, the savings represent billions in opportunity cost recovered annually for large dealers.
BlackRock's decision in November 2025 to approve BUIDL as trading collateral on Binance — with a simultaneous launch of a BNB Chain share class — demonstrated the collateral thesis in practice. The world's largest asset manager explicitly positioned its tokenized fund not as a standalone investment product, but as infrastructure for derivatives settlement.
The CFTC's December 2025 guidance (Letter No. 25-39) established the regulatory framework for tokenized collateral in U.S. derivatives markets. Key provisions:
If the August deadline holds, U.S. derivatives clearinghouses would have formal regulatory sanction to accept tokenized fund shares as margin. This would remove the current reliance on no-action relief and guidance letters, providing the permanent regulatory infrastructure that institutional risk committees require before scaling adoption.
The BIS Bulletin 115, published in March 2026, provides the most comprehensive regulatory risk assessment of the TMMF sector to date. The central findings:
Liquidity mismatch. TMMF tokens can be transferred instantly on-chain, but the underlying money market instruments settle on T+1 cycles (or longer for some repo agreements). Under normal conditions, this mismatch is manageable. During periods of market stress, mass redemption requests could exhaust available liquidity before underlying assets settle, creating a run dynamic functionally identical to traditional money market fund stress — but operating at blockchain speed.
Concentrated holder base. A small number of large holders dominate TMMF positions. The BIS flagged that this concentration increases the probability of sudden, large outflows that could trigger the liquidity mismatch described above.
Stablecoin contagion channel. Several TMMFs offer instant redemption facilities through partnerships with stablecoin issuers, allowing whitelisted investors to exchange fund tokens for stablecoins. This creates a bidirectional contagion pathway: stress in stablecoin markets could trigger TMMF redemptions, and TMMF redemption pressure could destabilize partnered stablecoin reserves. The BIS noted this channel "introduces additional vectors for shock propagation" between the TMMF and stablecoin markets.
Operational risk. Reliance on public blockchain infrastructure exposes funds to smart contract vulnerabilities, cyber-attacks, and service outages. The BIS noted these risks are additive to, not substitutes for, the traditional operational risks of fund management.
The New York Federal Reserve's Liberty Street Economics blog published a parallel analysis in September 2025 examining the financial stability implications of tokenized investment funds, reaching broadly consistent conclusions about liquidity risk amplification.
The competitive battle among tokenized fund issuers has shifted from single-chain deployment to multi-chain distribution. BlackRock's BUIDL is now available across nine blockchains. Franklin Templeton's FOBXX spans eight. This reflects a pragmatic calculation: institutional demand is fragmented across blockchain ecosystems, and issuers that limit deployment to Ethereum alone forfeit capital sitting on Solana, Avalanche, or Aptos.
The multi-chain approach introduces its own complexity. Each blockchain deployment requires separate smart contract audits, compliance configurations, and liquidity provision arrangements. Wormhole, the cross-chain messaging protocol, facilitated BlackRock's expansion to BNB Chain, providing interoperability infrastructure between share classes on different networks.
Ethereum remains the primary settlement layer. According to BIS data, the majority of TMMF AUM is deployed on Ethereum, consistent with institutional preference for the network's validator set size, time-in-market, and regulatory familiarity. However, Ethereum's share of BUIDL specifically has declined 60% as BlackRock has distributed across alternative chains, according to The Defiant.
The tokenized money market fund sector has passed the proof-of-concept stage. At $9 billion in AUM, it is large enough to attract BIS risk assessments and CFTC rulemaking, yet small enough relative to the $6.7 trillion traditional MMF industry that the growth curve has substantial room to extend. The March 2026 convergence of Invesco's entry, Franklin Templeton's ETF tokenization, and the CFTC's collateral rulemaking deadline marks a structural inflection: three of the five largest traditional asset managers now operate tokenized fund products on public blockchains.
The remaining question is not adoption — that trajectory is established. It is plumbing. The BIS liquidity mismatch warning, the stablecoin contagion channel, and the concentrated holder base all describe a sector that has outgrown its infrastructure. The CFTC's August 2026 deadline represents the first attempt at permanent regulatory architecture. Whether that timeline holds will determine whether tokenized funds evolve into a standard institutional collateral layer or remain a parallel experiment operating on temporary regulatory accommodations.
The data is clear on one point: the institutions are not waiting for the regulations to be finalized. They are building in production.
