Looking at utilisation alone misses something. For instance, tokenised gold should behave like gold; most holders want exposure, not yield. The low utilisation reflects the asset, not a failure of the market.
The State of RWAfi report points to three blockers keeping assets idle:
1) Tokens represent claims through legal wrappers and not direct ownership, which limits how freely they can move into DeFi.
2) Liquidity is fragmented across issuers, chains, and venues, making it harder for lending protocols to integrate them.
3) Regulation varies by jurisdiction, so what you can do with an asset onchain depends heavily on where you are.
The assets that have cracked it so far (private credit, gold) share one thing: their economic function maps naturally onto DeFi use cases like collateral and yield.
The ones still sitting idle mostly haven't found that fit yet.
