Research by Tanaka reveals that while the Real World Asset (RWA) sector is expanding rapidly, decentralized finance (DeFi) protocols have captured only a small fraction of this growth. Currently, just 10% of RWA liquidity is active in DeFi. For instance, tokenized gold and commodities are valued at approximately $7 billion on-chain, yet only $184 million is utilized within DeFi platforms. The study highlights that most tokenized Treasury products are constrained by compliance mechanisms, such as KYC requirements, whitelists, and transfer agents. Products like BUIDL, FOBXX, USTB, and OUSG manage substantial assets but face limitations due to qualified purchaser checks and redemption windows, restricting their integration into DeFi.
