The chart visualises the algorithmic relationship between supply and demand. The sharp rise (kink) typically occurs at 80-90% utilisation to protect liquidity.
Think of Utilisation as the 'Occupancy Rate' of a hotel. A 100% rate makes the most money, but leaves no room for error. A 0% rate is safe but unprofitable.
USDT is currently sitting at 84.81%. Equilibrium achieved. The protocol is effectively matching borrower demand with lender supply. At 84.81%, the system is in the 'sweet spot' of the interest rate curve.
Forecast: Cost of capital is rising. The protocol is algorithmically increasing rates to discourage new loans and protect the remaining liquidity buffer. Traders should monitor this metric daily, as it precedes APY changes.
Projecting pool stability under hypothetical high-demand scenarios.
| Scenario | Remaining Liquidity | Risk Level |
|---|---|---|
| Current State | $45,087,576 | High |
| At 90% Utilisation | $29,682,407 | Critical |
| At 95% Utilisation | $14,841,203 | Insolvent Risk |
Utilisation Rate: The percentage of the pool's total capital currently lent out to borrowers. It is the primary driver of interest rates in DeFi.
The Kink: A specific point in the interest rate curve (usually 80-90%) where borrowing costs jump exponentially to discourage depleting the pool entirely.
Safety Buffer: The remaining 15.2% of liquidity ensures lenders can withdraw their assets without waiting for borrowers to repay loans.
The Utilisation Rate is the single most important metric in DeFi lending. It balances the ecosystem. If utilisation is too low (e.g., 10%), there is too much idle capital earning no interest, leading to low APY for lenders. If utilisation is too high (e.g., 99%), there is a "liquidity crunch," meaning lenders cannot withdraw their funds until borrowers repay loans.
Protocols use an algorithmic "Interest Rate Model" to manage this. As utilisation rises, the borrowing interest rate rises to encourage repayments. Most protocols aim for an "Optimal Utilisation" rate (usually around 80%), where capital efficiency is maximised without risking a liquidity crisis.
