Tokenized Treasuries

Tokenized treasuries are blockchain tokens that represent ownership of real-world US government debt — typically Treasury bills (T-bills), bonds, or money market funds holding government securities — giving crypto users access to risk-free rates on-chain.


Why Tokenized Treasuries Matter

From 2022–2025, the US Federal Reserve raised interest rates significantly:

  • T-bills yielded 4–5%+ annually
  • DeFi stablecoin yields collapsed post-2021 to near-zero in many cases

This created a massive opportunity: on-chain dollars could earn nothing, while off-chain dollars earned 4–5% in T-bills. Tokenized treasuries bridge this gap — giving DeFi users yield without exiting to a bank.

How They Work

  1. User deposits USDC or USD with the issuer (KYC required for most)
  2. Issuer buys T-bills / money market securities with the USD
  3. Issuer mints an on-chain token representing the user’s share
  4. Token either:
    Accrues value: Token price increases as yield accumulates (e.g., OUSG)
    Distributes yield: Periodic USDC distributions (e.g., USDY)
  5. User can use tokens as DeFi collateral (on supported platforms)

Use in DeFi

Tokenized treasuries have become major DeFi collateral:

  • Maker/Sky: OUSG and BUIDL accepted as collateral for DAI
  • Morpho: USDY and BUIDL used in lending pools
  • Aave: Exploring RWA collateral onboarding

Market Size

By 2024, the tokenized treasury market exceeded $2 billion in on-chain AUM, with BUIDL becoming the largest product within months of launch due to BlackRock’s institutional distribution.
