Invesco, the $2.2 trillion asset manager, announced this week that it will take over investment management of Superstate’s Short Duration US Government Securities Fund, known by its ticker USTB. The deal marks Invesco’s formal entry into the tokenized treasury market, and it does so in an unusual way: not by building a competing product, but by stepping into an existing fund that crypto-native firm Superstate spent years constructing.

The fund currently holds around $967 million in assets under management, making it one of the five largest tokenized treasury products in existence. When the transition completes in Q2 2026, it will be renamed the Invesco Short Duration US Government Securities Fund while keeping its USTB ticker, its existing smart contracts, and its token address. The institutional clients who already hold shares will not need to do anything.

What Invesco gets and what Superstate keeps

The division of labour in this deal is worth understanding. Invesco is taking over portfolio management: buying and selling the short-term Treasury bills that back the fund, making the day-to-day investment decisions, applying the same discipline its Global Liquidity team uses across more than $200 billion in similar assets. That team, led by Laurie Brignac, has over four decades of experience in short-duration fixed income. USTB becomes one more mandate.

Superstate keeps everything else. The on-chain infrastructure, tokenized issuance, blockchain settlement, and digital transfer agency services all remain under Superstate’s ownership. Rather than giving any of that to Invesco, Superstate will expand it: adding more DeFi integrations, broadening support across the crypto ecosystem, and positioning its tokenization stack as a product other asset managers can use.

This is not, in other words, a traditional acquisition where one company absorbs another. It is closer to a white-label arrangement where Superstate built the rails and Invesco drives the train.

Why this deal matters for the RWA market

The tokenized treasury space has grown quickly. Total assets in tokenized U.S. government debt products have reached approximately $12 billion, up from near zero two years ago. BlackRock’s BUIDL fund, Franklin Templeton’s BENJI, and a handful of others have drawn institutional capital that wants yield, stability, and the operational efficiencies of blockchain settlement, mainly same-day liquidity and 24/7 transferability.

Each of those earlier products was built from the ground up by the institution offering it. BlackRock worked with Securitize to construct BUIDL. Franklin Templeton built its own custody and transfer infrastructure. The model was: hire crypto specialists, build the on-chain product, launch under your own brand.

Invesco chose a different path. Superstate had 150 institutional clients, a multi-year operating track record, and a fund structure that had already proven it could accept subscriptions in both dollars and USDC, process same-day redemptions, and hold up under real usage. Building that from scratch takes time. Taking it over does not.

Superstate founder Robert Leshner, who previously founded the DeFi lending protocol Compound, framed USTB explicitly as a prototype designed to show Wall Street that the model works. If his account is accurate, that prototype has now attracted its intended audience.

The yield picture

USTB’s 30-day yield currently sits near 3.44%, with holdings concentrated in Treasury bills maturing between March and May 2026. That is not a dramatically different return from what investors can get through traditional money market funds. The value proposition for institutional holders is not yield enhancement. It is settlement speed, programmability, and the ability to use USTB as collateral or integrate it with other on-chain protocols.

Same-day liquidity with USDC subscription and redemption is genuinely faster than the T+1 or T+2 settlement that still governs most traditional fund transactions. For trading firms and market makers who want to hold idle cash in something yield-bearing but keep it accessible within hours, that distinction matters.

What Superstate does next

Superstate raised an $82.5 million Series B in January 2026. That capital was not raised to compete with Invesco. It was raised to build the infrastructure layer that Invesco and others will eventually sit on top of.

The company is now positioned as a digital transfer agent and tokenization platform. In March, it was named as the first transfer agent eligible to mint blockchain-native securities on the NYSE-affiliated tokenized securities platform, following a Memorandum of Understanding between NYSE and Securitize. Superstate’s infrastructure is appearing in multiple places simultaneously.

The USTB deal fits this trajectory. Superstate handed off investment management to a firm with more credibility in fixed income and more distribution reach, while retaining ownership of the on-chain layer that it believes will become valuable infrastructure for a much larger market. Whether that bet pays out depends on how broadly tokenized securities catch on with institutional allocators over the next few years.

For now, Invesco has a tokenized treasury product and a path into a market it was previously absent from. Superstate has a well-known brand managing its flagship fund and fresh motivation to keep building the infrastructure underneath.
