Core Facts
According to a June 17 report from Korea’s Tokenpost, Fidelity Investments has launched a money market fund aimed at stablecoin issuers and institutional investors, positioned to absorb stablecoin issuers’ reserve assets. The product structure is reportedly aligned with the reserve requirements under the U.S. GENIUS Act. The report also notes that State Street launched a similarly positioned “stablecoin reserve money market fund” a few days earlier. The full official names, minimum subscription amounts, and fee structures of both products are currently only available through secondary reporting in Chinese-language media—as of the usdtcard editorial fact-check, no independent links to official Fidelity or State Street press releases could be found. The analysis below is based on the Tokenpost report cited above; readers should refer to disclosures on both issuers’ official websites for final terms.
This marks the second and third public bet by a major Wall Street asset manager on the “stablecoin reserve management” business line, following BlackRock’s BUIDL.
Editorial Take: Practical Impact on USDT Card Users
Short term (within 7 days): nothing changes for the card in your wallet. Whether you’re holding the MPCard Asia Elite variant, a Bybit Card, or a Coinbase Card, the settlement path for a swipe still runs Tether or Circle → card network → merchant bank. Whether an asset manager enters the reserve business has no bearing on the 5-second transaction that pays for your coffee.
Medium term (30 days), watch Tether’s reserve disclosure report. Tether publishes a quarterly reserve composition report, in which “U.S. Treasuries + money market funds” have long accounted for over 70%. If the Q3 report shows a share held with institutional money market funds like Fidelity or State Street, it would signal a shift in USDT’s reserve counterparty structure—from “Tether self-managed + third-party custody” toward “held on behalf by traditional asset managers.” This is a long-term positive for products deeply dependent on the USDT funding rail, such as the MPCard’s USDT channel—the more transparent the reserves, the more confident issuing banks will be about renewing partnerships.
Long term (90 days): After the U.S. GENIUS Act takes effect, the next step is implementing rules. If the Fidelity / State Street approach is recognized by regulators as a “compliant reserve arrangement,” issuers who haven’t entered this track will face a structural disadvantage in the U.S. market. This is neutral-to-positive for the USDC-based Coinbase Card, but adds pressure on smaller issuers relying on purely on-chain paths.
Historical Comparison: How This Differs from BUIDL, SVB, and MiCAR
Difference from BlackRock’s BUIDL in 2024: BUIDL is a tokenized money market fund—an on-chain asset in itself. The Fidelity / State Street products this time are traditional money market funds that absorb fiat reserves from stablecoin issuers. The former is “traditional assets moving on-chain”; the latter is “traditional assets absorbing on-chain business”—opposite directions.
Difference from the USDC de-pegging in March 2023: Back then, Circle’s reserve exposure to Silicon Valley Bank briefly pushed USDC down to 0.87. Circle’s official March 11, 2023 statement disclosed the size of its SVB exposure (see that statement for the exact figure). Today, Wall Street asset managers entering the reserve business essentially spreads “single commercial bank risk” across “multiple licensed asset managers’ money market funds”—a structural de-risking for both USDC and USDT, which are the underlying stablecoins for commonly used U-cards among Chinese users and Japan scenarios.
Difference from MiCAR in 2024: MiCAR is a framework EU legislators proactively drew around stablecoins; the Fidelity / State Street entry is the market proactively responding to new U.S. legislation. One is a compliance framework driving the industry; the other is the industry reverse-defining the boundaries of compliance—readers can compare the two regulatory philosophies side by side via the EU compliance guide and U.S. compliance guide.
Regulatory Boundaries: Where It’s Allowed, Gray, or Restricted
- Clearly allowed: In the U.S., stablecoin issuers holding money market funds from licensed asset managers as reserves is a path explicitly encouraged by the GENIUS Act.
- Gray zone: In the Asia-Pacific region—Japan’s Payment Services Act requires domestic custody of stablecoin reserves. Whether the Japan compliance guide recognizes U.S. asset managers’ money market funds as qualified reserve assets remains officially unstated; Hong Kong’s HKMA stablecoin regime is similarly undecided—see the Hong Kong compliance guide.
- Clearly restricted: Mainland China still has not granted retail legal status to stablecoins themselves, and progress at the asset management level does not change this.
Milestones Worth Watching Next
- Official English-language press releases from Fidelity and State Street—all current Chinese-language references trace back to Tokenpost’s secondary reporting; the product names, minimum investment amounts, and counterparty eligibility can only be confirmed once original documents are released.
- Tether’s Q3 2026 reserve report (expected in October)—watch for whether new asset management counterparties appear.
- Circle announcements—whether USDC follows suit by shifting reserves from existing partner banks to newly entered money market funds.
- GENIUS Act implementing rules—the timing of guidance from the U.S. Treasury and OCC on “qualified reserves.”
Editorial Recommendations
- Existing holders of MPCard, Bybit Card, or Coinbase Card: no action needed. This news doesn’t affect your next swipe.
- Users currently choosing a primary card for 2026: add “transparency of the issuer’s stablecoin reserve arrangements” to your selection checklist, but there’s no need to change your current decision because of this news.
- Users heavily reliant on USD subscriptions (ChatGPT Plus, Claude Code): improvements in USDC / USDT reserve structure are a medium-to-long-term positive, with no short-term impact on your payment success rate.
- Users planning to hold large amounts of USDT: wait for the Q3 reserve report before drawing conclusions—don’t adjust your holdings based on a single secondary report.
- What not to do: don’t trust any interpretation claiming “Fidelity’s entry means USDT will rise / fall”—institutionalization on the reserve side is a slow-moving structural variable, not a short-term price signal.
