High LTV and high leverage

More information on Loan-To-Value

LendBook offers higher leverage than other lending protocols.

To understand how, let’s examine how borrowers leverage their position. As in other protocols, they can borrow Y and swap them to amplify their position in X, or they can borrow X and swap them to short X. Borrowers can easily do loops of borrowing and swapping to amplify their leverage. High LTV translates into high leverage. Abstracting from gas and swap costs, the n-loop maximum leverage factor is:

\(1+LTV+LTV^2+...+LTV^n\)

Assuming borrowers could infinitely loop at the same limit price, their maximum leverage would be :

\(\dfrac{1}{1-maxLTV}\)

As the limit price gets closer to the market price, the maxLTV tends towards LLTV (Liquidation Loan-To-Value). We can then calculate the theoretical maximum leverage for each type of asset pair :

Asset tier LLTV pool step MaxLTV for pool closest to market price Theoretical Max leverage Examples
Pegged assets 99% 0.03% from 98.9% to 99% x100 DAI/USDC, wstETH/ETH
Correlated assets 98% 1% from 97% to 98% x50 USDM/USDC, FRAX/USDC
Volatile assets 96% 10% from 87.3% to 96% x25 ETH/USDC, WBTC/ETH
