Tokenized Treasury Funds Plug Fixed Income into the Internet

Tokenized Treasury funds have transformed the fixed income market by bringing it online. But how does the yield move onchain, and what gets lost or added along the way? The rate starts in short-term U.S. Treasuries and repo, which drive the gross yield. This is then passed through fund structures and token wrappers before hitting wallets, protocols, and markets that never close.

Fees, frictions, and risk accumulate at each step. When choosing a wrapper or using tokenized Treasuries as collateral, this is what makes or breaks your return. The key to understanding how yield moves onchain lies in the plumbing.

Short-term U.S. Treasuries and repo are the origin of the yield. With duration tiny and reinvestment frequent, policy changes pass through quickly. Tokenized money market fund shares, direct T-bill tokens, and synthetic yield tokens pay out differently: via rebases, NAV drift, or separate reward flows.

Settlement rails, such as delivery versus payment on permissioned ledgers and tokenized cash, are moving to production with big institutions, shrinking counterparty gaps. Access and liquidity come in two forms: KYC-only funds can be safer but less liquid, while new facilities aim to bridge to stablecoins after hours, tightening basis spreads.

Main leakages include management fees, mint-burn spreads, chain gas, custody costs, and slippage. Smart contract and legal risks sit on top. Use cases for tokenized Treasury funds range from parking idle cash to collateralizing loans or building basis trades.
