Uphold RLUSD Earn vs. Ethena Pay Earn+: Lending and Leverage Compared

Uphold launched RLUSD Earn, a lending product paying 4% APY on Ripple's RLUSD stablecoin, positioning it against Ethena's Pay Earn+ on USDe, which offers a variable rate tied to sUSDe yields that have ranged between roughly 8% and 12% APY. The comparison, framed around an equal $10,000 allocation on each product, highlights a structural difference: Uphold's rate is fixed, while Ethena's return depends on funding rates from its delta-neutral basis trade backing USDe, which currently carries about $5.5 billion in circulating supply. The article's core illustration shows that a leveraged loop—borrowing against RLUSD collateral to redeploy into higher-yielding assets—can flip negative when borrow costs rise above the earned yield, even if RLUSD holds its $1 peg throughout. That matters because it separates two risks often conflated: depeg risk, which is token-specific, and rate risk, which hits any leveraged stablecoin strategy when lending markets tighten. RLUSD's circulating supply stands near $950 million, a fraction of USDe's float, so small inflows or outflows move its on-chain lending rates more sharply. Watch next: whether Uphold holds the 4% floor as benchmark rates fall, and whether Ethena's funding-driven yields compress further if perp open interest on USDe pairs declines.
