Who Owns the Float: Why Morgan Stanley's Circle Downgrade Is About Money Rails, Not Just a Stock Target

Morgan Stanley cut its price target for Circle to $38 on Monday, down from $106, and downgraded the stock to Underweight. The move sent shares down roughly 4% and made headlines across crypto-adjacent financial media. The number is the headline, but it's not really the story. The story is what Morgan Stanley analyst James Faucette is pointing to beneath the valuation: that the economic model which made Circle's USDC stablecoin profitable is being unraveled from two directions at once.

Circle makes money by holding the reserves that back USDC. Those reserves sit primarily in short-term U.S. Treasury bills and government money market funds, and the interest they earn flows to Circle's bottom line. When USDC was growing fast and rates were high, that was a compounding engine. Now USDC growth is slowing, rates are trending down, and two new categories of product are offering institutions reasons to route their onchain dollars elsewhere.

The more revealing development isn't the price target itself. It's that we're watching the first serious contest over who gets to sit between the dollar and the blockchain - and Circle's claim to that position is no longer unchallenged.

Three Models of Onchain Dollar Liquidity

To understand what's shifting, it helps to sort the products that are competing for the same dollars. They sit on the same blockchains, settle in seconds, and all look like digital cash to the casual observer. But they are legally and economically different animals.

The first model is what Circle and Tether run: issuer-capture stablecoins. USDC is a payment token redeemable one-for-one for the U.S. dollar. It moves freely between wallets, 24 hours a day, and it pays the holder nothing. The issuer - Circle - holds the reserves, parks them in Treasuries, and keeps the interest. That's the business model. Under the GENIUS Act, which was signed into law in July 2025, compliant payment stablecoins are explicitly prohibited from paying interest or yield to holders. The yield stays with the issuer by design and by statute.

The second model is the tokenized money market fund. Products like BlackRock's BUIDL, Franklin Templeton's BENJI, and Circle's own USYC are registered securities that hold short-term Treasuries and overnight repo agreements. Their shares are issued as onchain tokens, and holders earn the fund's yield - roughly the front-end Treasury rate minus a small fee. BUIDL held about $2.5 billion in assets as of mid-2026; USYC, which Circle acquired through its purchase of Hashnote, grew to roughly $3 billion, making it the largest tokenized money market fund in the world. These are KYC-gated and transfer-restricted: they are not permissionless. But they do something USDC cannot: they let the holder, not the issuer, capture the reserve income.

The third model is the partner-governed stablecoin, and it's the newest entrant. Open USD, announced in late June by a consortium called Open Standard, brings together more than 140 firms including Visa, Mastercard, Stripe, BlackRock, Coinbase, Google, and Standard Chartered. Its design shares the reserve float among the distribution partners rather than concentrating it in a single issuer. Minting and redemption are zero-cost and uncapped. The product isn't live yet, but the architecture is a direct structural challenge to the single-issuer economics that Circle depends on.

The reason this taxonomy matters is that it maps to three different answers to the same question: who captures the value generated by onchain dollar liquidity?

The GENIUS Act Locked In the Split

The legal boundary between these models is now statutory, not just customary. The GENIUS Act - the Guiding and Establishing National Innovation for U.S. Stablecoins Act - created the federal framework for payment stablecoins and drew a line through the middle of the market. It defined what a payment stablecoin is, set reserve and disclosure requirements for issuers, and then prohibited yield payments to holders.

The prohibition was not an accident. It was the result of a sustained push by the Banking Policy Institute and other bank-aligned trade groups, who argued that if stablecoins could pay yield, they would function as unregulated savings accounts and pull deposits out of the banking system. The Treasury Department's own report estimated that yield-bearing stablecoins could trigger up to $6.6 trillion in deposit outflows. The GENIUS Act's yield ban was the compromise: let stablecoins exist, but keep them as payment instruments, not savings products.

What the law cemented is a structural problem for Circle. The company's revenue engine - earning interest on reserves while offering holders a free, permissionless payment token - is now legally bounded. Circle can keep its model, but it can never bridge the gap between stablecoin and yield-bearing product without running into the statute. That gap is exactly where its institutional customers are looking.

Why Morgan Stanley Thinks It Will Widen

Faucette's note is worth reading not because $38 is a precise prediction but because the mechanics of the squeeze are real. He cut his USDC supply forecasts by 33% for 2027 and 44% for 2028, which drove his GAAP earnings estimates roughly 20% below Wall Street consensus for 2028. He pointed to several forces that would erode USDC balances: tokenized money market funds, tokenized bank deposits, and Open USD's shared-governance model. He also flagged that the payments use case Circle needs to justify lower-margin fee revenue is still tiny - McKinsey data estimates only about $390 billion of identifiable payments out of roughly $35 trillion in adjusted stablecoin volume, or about half of one percent.

Morgan Stanley isn't alone in losing patience. Mizuho's Dan Dolev, who initiated coverage last Friday, rated Circle a Hold with a $45 target. JPMorgan started coverage at Underweight back in June 2025. Across 30 analysts, 16 rate the stock a Hold or Sell.

But TD Cowen went the other way, initiating with a Buy and an $82 target. Analyst Bryan Bergin argued that investors are fixated on reserve income while underappreciating Circle's pivot toward fee-based products - the Circle Payments Network, its cross-chain transfer protocol, StableFX, and the Arc blockchain. TD Cowen projects USDC circulation growing at a 31% compound annual rate through 2030 and expects fee revenue to expand faster than reserve income over time.

Both sides are right about parts of the picture. The question is which side of the balance sheet moves faster: Circle's diversification, or the fragmentation of the dollar liquidity pool it currently sits atop.

Circle Knows It

Circle's own filings and earnings calls acknowledge the threat. In its IPO registration statement, filed earlier this year, Circle warned that "certain major trading firms have moved, and will increasingly move away from, using stablecoins as collateral in favor of TMMFs" - tokenized money market funds. The prospectus also noted that competing TMMF issuers may not offer the same settlement speed as USDC, which is Circle's counter-argument. But the company then spent much of the same document describing its own TMMF product, USYC, and how it plans to let customers "move between the non-yield-bearing Circle payment stablecoins and USYC at the settlement speed of the blockchain."

That's telling. Circle is building the bridge between the two categories it once claimed were separate, because the market is already choosing between them. USYC is now Circle's largest non-USDC product and the world's biggest tokenized money market fund. The company is effectively competing with itself.

What This Changes

The Morgan Stanley downgrade crystallizes a structural shift that has been moving quietly beneath the surface for months. The question is no longer whether tokenized alternatives matter. They already do. The question is how much USDC's float will shrink as institutions that currently park dollars in USDC for convenience begin to demand yield, shared economics, or both.

Circle's answer - build fee revenue fast enough that shrinking reserve income doesn't kill the model - is a harder path than it sounds. Faucette's note calls agentic commerce "immaterial" at $41,900 in daily volume. Payments adoption is real but incremental. The fee-based revenue that TD Cowen counts on has to scale from a small base while the core business is being competed away.

I'm less interested in whether the stock hits $38 than in what the $38 target reveals about the system we're building. We are constructing three parallel layers of onchain dollar liquidity, each with a different legal form, a different claim on the yield, and a different set of beneficiaries. The GENIUS Act made the boundary between payment token and yield-bearing security permanent in U.S. law. What it didn't do was decide which one institutions prefer.

That preference will settle over the next two years, not through legislation but through balance sheets. Watch whether tokenized money market funds continue pulling institutional collateral away from stablecoins. Watch whether Open USD's consortium model actually ships and whether its partners use it over USDC in practice. Watch whether Circle's fee revenue can grow fast enough to matter before USDC's reserve income shrinks below the level that makes the stock look expensive at any price.

The float is the valuable asset in a stablecoin. The contest over who keeps it has just gotten its first institutional audience.
