Interest Rate Model Types: A Comparative Overview
A technical comparison of the most common interest rate model architectures, detailing their mechanics, risk profiles, and ideal use cases to help you choose the optimal foundation for your lending or borrowing protocol.
| Model Type | Mechanism | Risk Profile | Ideal For | Implementation Complexity |
|---|---|---|---|---|
Linear / Jump Rate | Interest rate changes linearly or with discrete jumps based on utilization | Predictable, moderate | General-purpose lending, stablecoin pools | Low to Medium |
Kinked Rate | Introduces a 'kink' point with different slopes above/below target utilization | Managed, incentivizes target | Protocols needing strong liquidity guidance | Medium |
Dynamic / Adaptive | Algorithmically adjusts parameters (e.g., slope, kink) based on market conditions | Sophisticated, requires tuning | Advanced protocols, volatile asset markets | High |
Yield-Based / Oracle-Driven | Rates are derived from external yield sources (e.g., staking rewards) | Exogenous, market-linked | Liquid staking tokens (LSTs), yield-bearing collateral | High |
Time-Based / Vesting | Interest rate decays or changes based on loan duration | Encourages specific behaviors | Fixed-term loans, credit delegation | Medium |
Custom Hybrid | Combines multiple models (e.g., kinked base + oracle premium) | Tailored, maximum flexibility | Niche products, competitive differentiation | Custom / Very High |

METHODOLOGY
Our Design and Implementation Process
A systematic, four-phase approach to building secure, efficient, and market-ready interest rate models. We move from strategic analysis to production deployment with clear deliverables at each stage.
01
Phase 1: Market & Risk Analysis
We analyze target assets, competitor models, and on-chain data to define optimal rate parameters. Deliverables include a risk-adjusted target rate curve and a volatility assessment report.
