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?
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.
How do I check pool parameters?
