This article explores why fixed-rate lending hasn't gained traction in decentralized finance (DeFi). It argues that while institutional borrowers need predictable rates, the flexibility of on-chain lending options often conflicts with fixed-rate demands. A proposed solution is to create a rate exchange layer that allows for better matching between borrowers and lenders.

Fixed-rate lending hasn't gained traction on-chain due to a mismatch between borrower demand and lender preferences. Institutions, such as private equity firms and real estate sponsors, seek fixed rates for cash-flow predictability and to mitigate exposure to rising interest rates. In contrast, lenders often favor floating rates because they maintain profit margins and reduce risks associated with rate volatility. Without consistent borrower demand for fixed-rate products in decentralized finance (DeFi), these loans struggle to gain liquidity and scale.
Current borrowing from platforms like Aave illustrates two main borrower groups: long-term holders who want liquidity without selling assets and yield loopers who aim for higher net yields through recursive strategies. However, looping strategies falter when borrowing rates fluctuate, erasing potential profits. If both borrowing and yield rates were fixed, it would stabilize these strategies, allowing for better capital deployment. Despite significant demand, fixed-rate loans haven't expanded due to the inherent flexibility valued by on-chain participants, who prefer to adjust or exit positions without penalties.
Lenders are typically unwilling to sacrifice flexibility for fixed rates unless compensated with high yields. For instance, Pendle PT holders face risks and generally seek yields of 10% or more, which is unsustainable for non-speculative borrowers. Platforms like Term Finance and TermMax have struggled to attract liquidity because borrowers find fixed rates unattractive compared to lower floating rates on Aave. The article proposes a solution: instead of pairing fixed-rate borrowers with fixed-rate lenders, create a market where fixed-rate borrowers can interact with rate traders. This would allow borrowers to access capital without locking in full loan terms, enhancing capital efficiency while tapping into the liquidity and security of established platforms like Aave.
