# Why Fixed Rate?

> Understanding the volatility problem in DeFi lending and how fixed rates solve it

## 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

<Warning>
  Variable rates in DeFi can swing **78%+ in a single day**. This makes financial planning nearly impossible.
</Warning>

| Protocol      | Average Daily Volatility | Max Single-Day Swing |
| ------------- | ------------------------ | -------------------- |
| Aave USDC     | 15-25%                   | 78%                  |
| Compound USDC | 12-20%                   | 65%                  |
| Centuari      | **0%**                   | **0%**               |

### Real Consequences

  <Card title="For Lenders" icon="chart-line-down">
    You deposit expecting 8% APY. A week later, rates drop to 2%. Your yield projections are worthless.
  </Card>

  <Card title="For Borrowers" icon="triangle-exclamation">
    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

<Info>
  Research shows that **80% of DeFi liquidations** occur not because collateral prices dropped, but because borrowing rates spiked unexpectedly.
</Info>

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:

  <Accordion title="Financial Planning" icon="calculator">
    CFOs need to know exact interest expenses for quarterly reports. Variable rates make this impossible.
  </Accordion>

  <Accordion title="Regulatory Compliance" icon="scale-balanced">
    Many jurisdictions require clear disclosure of borrowing costs. Variable rates complicate compliance.
  </Accordion>

  <Accordion title="Risk Management" icon="shield-halved">
    Hedging strategies require predictable cash flows. Variable rates introduce unhedgeable interest rate risk.
  </Accordion>

  <Accordion title="Audit Requirements" icon="clipboard-check">
    Auditors need to verify expected vs. actual returns. Variable rates create reconciliation nightmares.
