Stablecoin Yield vs Short-Term T-Bill Arbitrage

Compare on-chain stablecoin yields to T-bills, park capital where risk-adjusted return wins.

Overview

Aave, Compound, Morpho, Maker DSR, Ondo (OUSG), Mountain Protocol (USDM) yield 4–8% on stablecoins. Compare to 4-week T-bill (~5% fed rate) — decide risk/return based on smart-contract risk, protocol solvency, custody. For tax: on-chain yields = ordinary income (uncertain sourcing); T-bill interest = federally taxable, state-exempt. Some UHNW rotate between the two based on rate spreads.
