The Problem with Variable Rates

Traditional DeFi lending protocols like Aave and Compound use variable interest rates that fluctuate based on utilization. While this works for the protocol, it creates significant problems for users.

Rate Volatility is Extreme

Variable rates in DeFi can swing 78%+ in a single day. This makes financial planning nearly impossible.

Real Consequences

For Lenders

You deposit expecting 8% APY. A week later, rates drop to 2%. Your yield projections are worthless.

For Borrowers

You borrow at 5% APY for a leveraged trade. Rates spike to 25%. Your position becomes unprofitable, or worse, liquidated.

80% of Liquidations Are Rate-Driven

Research shows that 80% of DeFi liquidations occur not because collateral prices dropped, but because borrowing rates spiked unexpectedly.
When rates surge:
  1. Borrower’s health factor deteriorates faster than anticipated
  2. They have no time to add collateral or repay
  3. Liquidation bots execute before borrowers can react
Fixed rates eliminate this entire category of risk.

Why Institutions Need Fixed Rates

Traditional finance operates almost entirely on fixed rates. Here’s why:
CFOs need to know exact interest expenses for quarterly reports. Variable rates make this impossible.
Many jurisdictions require clear disclosure of borrowing costs. Variable rates complicate compliance.
Hedging strategies require predictable cash flows. Variable rates introduce unhedgeable interest rate risk.
Auditors need to verify expected vs. actual returns. Variable rates create reconciliation nightmares.
