Invesco Short Duration US Government Securities Fund

Invesco Short Duration US Government Securities Fund (USTB) is a tokenized private fund that holds short-duration U.S. Treasury and Agency securities and issues on-chain shares under the USTB ticker, letting qualified investors earn a rate targeting the federal funds rate directly on-chain.

How USDC subscriptions and redemptions work

Its distinguishing plumbing is USDC-native access: accepted U.S. Qualified Purchasers subscribe and redeem using USDC at a daily NAV, and an Ethereum-based allowlist enforces who can own and transfer shares while keeping compliance on-chain. The fund charges a lean 0.15% management fee, and its design anticipates future peer-to-peer transfers among approved holders.

Flexible self-custody for USTB shares

Custody is unusually flexible for a regulated fund. Holders can self-custody USTB in any allowlisted address — an EOA, a multisig, or an MPC wallet — or rely on a qualified custodian. That optionality, rare among tokenized treasuries, is the fund's pitch: institutional yield with wallet-level control rather than a walled custodian.

Why crypto treasuries use USTB

The bull case is efficiency and composability. Instant USDC subscription and redemption, self-custody, and a rock-bottom fee make USTB a cash-management tool that behaves like crypto while paying government-securities yield — attractive to crypto-native treasuries and funds parking dollars between trades.

Access limits and RWA risks to weigh

The constraints are access and dependency. Eligibility is limited to Qualified Purchasers, so this is not a retail instrument, and value is entirely rate-driven — returns compress if the Fed eases. RWA risks apply: reliance on the administrator's NAV, the allowlist contract, USDC's own peg as the settlement leg, and custodian soundness. It is a regulated yield vehicle for eligible institutions, best framed as tokenized short-term government exposure with crypto-grade settlement.
