Bernstein: Clarity Act yield compromise locks in Circle's float income edge as stablecoin supply hits records!

Bernstein analysts say the yield compromise embedded in the Clarity Act effectively ends the rate arms race among stablecoin issuers — and in doing so, cements Circle's float income model as the structural winner. Rather than competing on yield passed to holders, issuers will now compete on trust, compliance, and distribution, all areas where USDC already leads.
