Tokenised money market funds — short-dated government paper wrapped in a transferable on-chain claim — have quietly become one of the fastest-growing instruments in digital assets.
Trading firms are the main users. A fund unit that pays a yield and can be posted as collateral is strictly better than an idle stablecoin balance, provided the venue accepts it.
Exchanges have begun to accommodate that preference, adding tokenised funds to margin frameworks with haircuts that reflect redemption timelines rather than price volatility.
The growth has implications for stablecoin issuers, whose business model depends on holding reserves that earn a yield they do not pass on. Every dollar that migrates into a yield-bearing wrapper is a dollar of foregone revenue.
Regulators have so far treated the instruments conventionally, as fund units subject to existing rules. Distribution, rather than the wrapper, remains the area drawing supervisory attention.
