Ethena Labs USDe Growth Surges 100% in Three Weeks Driven by Pendle Finance Borrow Loops

Ethena Labs has achieved a significant milestone, surpassing $1 billion in USDe growth within just three weeks. This remarkable surge is primarily driven by the increasing adoption of Pendle Finance borrow loops, a strategy that allows users to leverage principal tokens (PTs) to generate higher yields from interest-bearing assets. The borrow loop strategy has positioned Ethena’s synthetic dollar (USDe) and related assets (sUSDe, eUSDe) as key players in the yield-seeking ecosystem within the decentralized finance (DeFi) landscape.
The rapid growth in USDe reflects a strong market appetite for structured yield products that offer predictable returns, especially in the volatile crypto lending environment. Ethena’s integration with Pendle and various money market platforms has facilitated this growth, making its synthetic stablecoins attractive to both individual and institutional investors seeking low-risk, high-yield strategies.
In response to the growing demand, Aave has increased its Principal Token (PT) cap for sUSDe by $300 million. This move underscores confidence in Ethena’s protocol and the increasing appetite for yield-generating assets across DeFi. By raising the PT cap, Aave allows for greater capital inflows and more efficient use of sUSDe within borrowing loops on the platform. This expansion is expected to attract larger-scale participation, particularly from DeFi-native treasuries and structured product funds.
Ethena Labs has also announced the launch of a new August-dated Pendle pool for USDe on BNB Chain. This strategic expansion beyond Ethereum and other Layer 2 solutions aims to deepen liquidity and broaden exposure for USDe holders, especially those operating in the BNB Chain ecosystem. The new pool is expected to benefit from lower transaction fees and strong retail adoption on BNB Chain, aligning with Pendle’s roadmap of multi-chain liquidity optimization. This move reflects the broader trend of interoperable finance, where protocols seek exposure across major Layer 1 and Layer 2 networks.
Despite the rising demand, borrow rates on major money market platforms remain below PT yields, making the arbitrage loop attractive. On Aave, borrow rates hover slightly above 5%, while Lista offers USD1 borrow rates around 3.5%. Meanwhile, PT yields for eUSDe, USDe, and sUSDe have consistently ranged between 8–11% over the past month. This interest rate differential is the core engine of the borrow loop strategy, where users borrow against stable assets at relatively low rates, purchase PTs that yield higher returns, and repeat the cycle to amplify gains. While this strategy is not without risks, particularly if borrow rates spike or PT prices decline, it remains appealing in the current environment.
The rapid growth of Ethena Labs raises questions about sustainability. Critics have cautioned against over-leverage and systemic risk in the DeFi borrow-loop model. However, Ethena’s approach, anchored by synthetic stablecoin architecture and robust partner integrations, aims to mitigate some of these concerns. For now, the yield remains, the demand is rising, and Ethena Labs appears firmly positioned at the intersection of DeFi innovation and capital efficiency. The coming months will reveal whether this momentum can hold, especially as interest rate dynamics and regulatory scrutiny evolve.
