"The right way is native tokenization, working with the issuer, where the token is the real share with the same rights and value." — Carlos Domingo, CEO, Securitize
The $322 billion stablecoin market has triggered a new front in Wall Street's asset management wars: the fight to manage stablecoin reserves. JPMorgan, BlackRock, Morgan Stanley, Franklin Templeton, and Goldman Sachs have all filed or launched tokenized money market funds explicitly designed to capture the reserve deposits that stablecoin issuers are legally required to maintain under the GENIUS Act, signed into law in July 2025.
The stakes are substantial. Tether alone holds $141 billion in U.S. Treasury exposure. Circle holds between $45 billion and $55 billion. Under GENIUS Act reserve requirements, every dollar of stablecoin in circulation must be backed one-to-one by eligible reserve assets — primarily short-dated Treasuries, cash, and overnight repos. That creates a captive demand pool worth hundreds of billions, and Wall Street wants to intermediate it through tokenized fund shares rather than letting issuers manage reserves independently.
The result is an emerging market infrastructure layer where traditional asset managers issue blockchain-native fund tokens that serve simultaneously as regulated money market instruments and stablecoin reserve collateral. Six months after the GENIUS Act's passage, at least five major financial institutions have entered this market.
The Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act), signed into law in 2025, created the first comprehensive federal framework for payment stablecoins. Its reserve requirements define the addressable market that Wall Street is now targeting.
Under the Act, permitted payment stablecoin issuers must maintain reserves backing their outstanding tokens on an at least one-to-one basis. Eligible reserves are narrowly defined: U.S. coins and currency, demand deposits at insured depository institutions, U.S. Treasury securities, repurchase and reverse repurchase agreements backed by Treasuries, and — critically — tokenized representations of these eligible assets that meet specified criteria. Stablecoins themselves and other crypto assets are explicitly excluded from eligibility.
The law requires issuers to redeem stablecoins within two business days, imposing strict liquidity constraints on reserve portfolios. Regulators must finalize implementation rules by July 18, 2026, one year after enactment.
The effect is straightforward: every stablecoin issuer operating under U.S. law needs a compliant, liquid, and auditable reserve portfolio. For an industry managing $322 billion in outstanding tokens as of May 2026, according to KuCoin data, that translates to hundreds of billions in mandated demand for short-duration Treasury instruments.
Five major financial institutions have moved to capture this market in the first half of 2026. Their products share a common architecture: registered or private money market funds that issue blockchain-native tokens, allowing stablecoin issuers to hold compliant reserves in tokenized form.
BlackRock operates the largest existing tokenized Treasury fund, BUIDL (BlackRock USD Institutional Digital Liquidity Fund), with approximately $2.5 billion in assets across eight blockchains including Ethereum, Solana, and Aptos. In May 2026, the firm filed for two additional products — BSTBL and BRSRV — both investing in cash and short-term U.S. Treasuries and designed for stablecoin reserve compliance, according to SEC filings dated May 8, 2026.
JPMorgan launched the OnChain Liquidity-Token Money Market Fund (JLTXX) on May 13, 2026, a registered government money market fund deployed on the public Ethereum blockchain via the firm's Kinexys Digital Assets platform. JPMorgan Asset Management seeded the fund with $100 million, with Anchorage Digital as an early participant. The fund explicitly states it invests only in GENIUS Act-eligible reserve assets, noting that its yield may be lower than other money market funds as a consequence. JPMorgan also operates the MONY fund for private fund structures. The JLTXX token is live on Ethereum at address 0x09864f52B035AE22eE739dFa5c748fA080D07bD8.
Morgan Stanley entered with the MSILF Stablecoin Reserves Portfolio (ticker: MSNXX), launched on April 16, 2026. The fund invests exclusively in cash, T-bills, notes, and bonds with maturities of 93 days or fewer, plus overnight repos collateralized by U.S. securities. The fund maintains a weighted average maturity of approximately 12 days and charges a net expense ratio of 0.20%. As of late April 2026, assets stood at roughly $1 million — a figure that reflects the fund's nascent stage rather than market demand.
Franklin Templeton adapted two existing fund structures for stablecoin reserve compatibility. The Western Asset Institutional Treasury Obligations Fund (LUIXX) invests exclusively in short-term U.S. government obligations and is positioned as "plug-and-play infrastructure" for payment stablecoin treasuries. The Western Asset Institutional Treasury Reserves Fund (DIGXX) added a blockchain-enabled "Digital Institutional" share class for 24/7 onchain collateral and cash management. Franklin Templeton's BENJI tokenization platform now spans eight blockchains.
Goldman Sachs announced on June 4, 2026, a tokenized real estate fund with Apex Group and Archax using its GS DAP platform. While not a direct stablecoin reserve product, the initiative extends Goldman's tokenization infrastructure — the same GS DAP platform that could service future reserve-eligible fund products.
The business case for capturing stablecoin reserves is built on management fees applied to a mandatory, growing asset base. At a 0.20% expense ratio — the rate Morgan Stanley's MSNXX charges — $100 billion in stablecoin reserves under management would generate $200 million in annual fee revenue. At BlackRock's scale, even basis-point-level fee compression on a multi-hundred-billion-dollar pool represents significant recurring revenue.
The economic incentive extends beyond management fees. Serving as a stablecoin reserve manager creates a durable institutional relationship with issuers, generates data on stablecoin flows, and positions asset managers as infrastructure providers in the payments stack — a market that processed over $27 trillion in stablecoin transaction volume in 2024, according to Chainalysis data.
For stablecoin issuers, the calculation is different. Tether reported over $10 billion in profit in 2025, driven largely by yield earned on its $141 billion Treasury portfolio. Outsourcing reserve management to fund managers compresses that margin. The GENIUS Act's prohibition on paying interest or yield on stablecoins means issuers retain the spread between reserve yield and zero-cost stablecoin liabilities — but fund management fees eat into that spread.
This creates a tension: smaller issuers benefit from outsourced compliance and custody, while large issuers like Tether may prefer to maintain direct Treasury holdings to maximize revenue. Tether's Q1 2026 attestation reported $122 billion in direct T-bill holdings and $141 billion in total Treasury exposure, managed through its own operations and attested quarterly by BDO Italia.
Two parallel regulatory processes are shaping how this market will operate.
The OCC issued a notice of proposed rulemaking on February 25, 2026, to implement the GENIUS Act for OCC-licensed payment stablecoin issuers. The proposed rule covers application requirements, permissible activity limits, reserve maintenance obligations, redemption standards, and capital adequacy requirements. The 60-day comment period closed on May 1, 2026.
The FDIC Board approved its own proposed rulemaking on April 7, 2026, establishing requirements for FDIC-supervised stablecoin issuers and insured depository institutions engaged in stablecoin activities. The FDIC rule requires permitted issuers to redeem stablecoins within two business days, and provides clarity on deposit insurance coverage for reserves held at insured depository institutions. The FDIC comment period closes June 9, 2026.
The Treasury Department issued a separate proposed rule addressing anti-money laundering and sanctions compliance requirements for permitted stablecoin issuers, published in the Federal Register on April 10, 2026.
All three agencies face a July 18, 2026 statutory deadline to finalize regulations, one year after the GENIUS Act's enactment. The final rules will determine key operational details: which tokenized fund structures qualify as eligible reserves, what custodial requirements apply, and how blockchain-based attestation maps to traditional audit requirements.
The reserve mandate has a macroeconomic dimension. Stablecoin issuers have become among the largest holders of U.S. government debt. Tether ranks as the 17th largest holder of U.S. Treasuries globally and the largest non-sovereign holder, according to its 2025 year-end attestation. Circle holds between $45 billion and $55 billion in T-bills, per company transparency reports.
Combined, the two largest stablecoin issuers hold an estimated $186 billion to $196 billion in U.S. Treasuries — more than Saudi Arabia's holdings, according to the IMF's July 2025 External Sector Report. At the $322 billion total stablecoin market size reported in May 2026, the sector's aggregate Treasury demand approaches the holdings of major sovereign nations.
According to an S&P Global Ratings analysis, increased international adoption of dollar-backed stablecoins could raise structural demand for U.S. Treasuries, reinforcing the dollar's reserve currency status. ARK Invest has argued that stablecoins could become "one of the most resilient financial allies" for U.S. government borrowing.
The GENIUS Act effectively codifies this relationship. By mandating Treasury-heavy reserve portfolios, the law ensures that stablecoin market growth mechanically increases demand for U.S. government debt. If stablecoin supply doubles to $640 billion — a trajectory consistent with current growth rates — the sector would need to absorb an additional $320 billion in Treasuries, equivalent to roughly 1% of the $35 trillion U.S. national debt.
Several unresolved issues could reshape this market.
Concentration risk. If a small number of tokenized funds become the dominant reserve vehicles for most stablecoin issuers, a run on stablecoins could trigger simultaneous large-scale redemptions from those funds. The two-business-day redemption requirement imposes liquidity obligations that could strain fund structures during market stress.
Tokenized deposits vs. tokenized funds. JPMorgan and Bank of New York Mellon already offer tokenized deposits to institutional clients on private and privacy-enabled public blockchains. Tokenized deposits carry FDIC insurance up to coverage limits — a structural advantage over money market fund shares. According to Simon McLoughlin, CEO of Uphold, tokenized deposits could disrupt stablecoin dominance by combining digital-native functionality with bank-level protections. Whether bank-issued tokenized deposits eventually compete with or complement stablecoin reserve funds remains unclear.
Yield compression. The GENIUS Act prohibits stablecoin issuers from paying interest or yield to holders, but fund managers earning fees on reserves face no such constraint. As more managers enter the market and compete for reserve deposits, fee compression will follow. The question is whether the business remains attractive at 5-10 basis points on a $300 billion pool or requires scale advantages that favor only the largest managers.
International regulatory divergence. A separate webthreepedia comparative analysis has documented how the Fed, Bank of England, and ECB are pursuing different stablecoin regulatory strategies. Stablecoin issuers operating globally face a patchwork of reserve requirements, and whether U.S.-registered tokenized funds qualify as eligible reserves under MiCA or other international frameworks is unresolved.
The GENIUS Act has accomplished what years of crypto-native experimentation could not: it created a regulated, mandated market for tokenized Treasury products with a built-in customer base worth hundreds of billions of dollars. Wall Street responded predictably — within six months, the largest names in asset management launched products designed to capture stablecoin reserve flows.
The competitive dynamics are straightforward. Stablecoin supply is growing. Reserve requirements are mandatory. Tokenized fund shares offer compliance-ready, on-chain reserve management. The institutions that establish early relationships with issuers and achieve scale will capture recurring fee revenue on an expanding asset base.
What remains uncertain is the equilibrium structure. Tether and Circle may resist outsourcing reserve management to protect profit margins. Fee compression will intensify as more managers enter. Tokenized bank deposits could emerge as a competing format. And final regulatory rules — due in six weeks — will determine which fund structures actually qualify.
The stablecoin reserve market is not speculative. It is a regulatory creation, backed by statute, with defined participants and measurable economics. For Wall Street, it represents a new asset-gathering channel built on blockchain infrastructure. For the stablecoin industry, it represents the cost of regulatory legitimacy.
