How does yield on Suilend work?

In this article we'll explain how yield works in lending protocols like Suilend and why it's considered a reliable yield source in DeFi.

Where does the yield come from?

Depositing into the USDC pool on the Suilend main market.

When you deposit on Suilend, you’re supplying liquidity to a shared pool. Borrowers take loans from that same pool by posting collateral. The interest borrowers pay becomes the yield depositors earn, minus a small protocol fee, usually 20% of the borrow interest rate, called the interest rate spread.

Utilization

Lending rates revolve around one key metric: utilization.

• If utilization is low: liquidity is abundant, then rates stay low.

• If utilization is high: liquidity is scarce, then rates rise to attract deposits.

Suilend uses a dynamic interest rate curve to set rates automatically.

What happens when rates rise?

When liquidity gets tight, interest rates rise.

This discourages excessive borrowing and rewards depositors with higher yields - keeping the market in balance.

As seen below: USDC rates spiked but quickly reverted to the average 9.7% APR as liquidity returned.
