Invesco Files Tokenized Stablecoin Reserve Fund

The Situation

Invesco filed with the SEC to add the Invesco Stablecoin Reserves Onchain Fund to its Short-Term Investments Trust, according to crypto.news, CoinDesk and The Block. The fund would operate as a Rule 2a-7 government money market fund, maintain a stable $1 NAV, and invest in cash, cash equivalents, repo agreements and short-term U.S. Treasuries.

Superstate will provide the tokenization layer and act as sub-transfer agent, with fund shares recorded on “designated” public blockchains that were not named in the filing. The structure targets stablecoin issuers looking for reserve assets that satisfy the GENIUS Act’s permitted-asset framework.

When we covered bank-led tokenized deposit tests on June 22, the open question was whether banks would pull settlement cash back inside the deposit perimeter. Invesco is taking the other side of that buildout: if payment stablecoins scale outside bank deposits, the reserve book becomes an asset-management mandate.

The Mechanism

• Stablecoin reserves become a fee pool for traditional managers. Invesco is not launching a payment token. It is positioning a government MMF as the reserve account behind issuers that need one-to-one backing in cash-like instruments.

• Superstate controls the onchain shareholder record. Invesco manages the portfolio; Superstate tokenizes the shares and maintains the blockchain-based registry as sub-transfer agent. The counterparty stack is asset-manager plus transfer-agent infrastructure, not exchange custody.

• Public chains get used inside a qualified fund perimeter. The filing references designated public blockchains, but access to the fund still runs through a registered money-market structure and stablecoin-reserve use case. Public rail. Controlled holder base.

• Daily liquidity matters more than secondary trading. Stablecoin issuers need reserves they can rebalance against mint and redemption flows. A tokenized fund share gives issuers faster operational visibility and potentially faster transferability, but the core product remains a 2a-7 government MMF.

• BlackRock, State Street, ProShares and others are now competing for the same reserve wallet. CoinDesk notes that Invesco joins a growing group of asset managers filing or launching stablecoin-reserve vehicles as GENIUS turns reserve eligibility into product design.

• The Invesco-Superstate tie-up is no longer experimental. Earlier this year, Invesco took over management of Superstate’s roughly $900 million tokenized Treasury fund, per CoinDesk. This filing extends that relationship from tokenized Treasury exposure into issuer reserve management.

The State of Play

Market Position

Invesco brings $2.45 trillion in AUM, according to The Block, and is entering a market where scale, liquidity operations and brand trust matter more than token novelty. Stablecoin issuers need reserve managers that can handle cash, T-bills, repo, subscriptions, redemptions and auditability without creating duration or counterparty surprises.

The product also tightens the link between tokenized Treasuries and stablecoin infrastructure. When we covered Ripple’s RLUSD Japan launch on June 25, distribution was the live issue: regulated corridors, local approvals and payment flow. Invesco’s filing sits behind that front end. Issuers that win payment volume will need institutional reserve partners; reserve managers that win mandates get recurring AUM tied to stablecoin float.

Regulatory Landscape

The filing is built around the GENIUS Act’s payment-stablecoin reserve requirements, which call for one-to-one backing in safe and liquid assets. Invesco is not waiting for a vague “tokenization” exemption. It is using an existing registered fund architecture — Short-Term Investments Trust plus Rule 2a-7 government MMF treatment — and adding onchain share registration through Superstate.

The regulatory design also avoids the hardest version of public-chain fund distribution. Shares may be represented on public blockchains, but the reserve use case narrows the expected holder base to stablecoin issuers and eligible counterparties rather than retail token holders. The filing still leaves open which chains will be designated and how transfer restrictions, whitelisting and redemption operations will work in production.

Key Data

• Fund name: Invesco Stablecoin Reserves Onchain Fund.

• Legal home: Invesco Short-Term Investments Trust, a Delaware statutory trust structure used for money-market-style portfolios.

• Regulatory category: Rule 2a-7 government money market fund with a targeted stable $1 NAV.

• Eligible assets: Cash, cash equivalents, repurchase agreements and short-term U.S. Treasury securities.

• Tokenization provider: Superstate, acting as sub-transfer agent and maintaining the onchain shareholder registry on designated public blockchains.

By The Numbers

• Invesco AUM: $2.45 trillion as of May 31, per The Block.

• Superstate platform relationship: roughly $900 million in tokenized Treasury fund assets already moved under Invesco management earlier this year, per CoinDesk.

• Stablecoin market size: roughly $300 billion today, with Citi projecting up to $4 trillion by 2030, according to CoinDesk’s summary of the filing context.

What’s Next

The next catalyst is the SEC review process and any amendment that names the designated public blockchains, transfer controls and operational counterparties. Watch for whether Invesco limits access to stablecoin issuers only, how Superstate enforces eligible-holder rules onchain, and whether the first disclosed mandate comes from an existing issuer seeking GENIUS-compliant reserve treatment before the rulebook hardens.
