Proposal to optimize weETH collateral parameters on Ethereum Core by increasing LTV from 72.5% to 77.5%, increasing LT from 75% to 80%, and decreasing LB from 7.5% to 7%, based on strong liquidity, low-risk borrowing patterns, and minimal historical depegging.

Type
parameter change

Key changes

  • Increase Loan-to-Value (LTV) from 72.5% to 77.5%(medium)
  • Increase Liquidation Threshold (LT) from 75% to 80%(medium)
  • Decrease Liquidation Bonus (LB) from 7.5% to 7%(low)

Notable concerns

  • Liquidation bonus reduction from 7.5% to 7% requires careful monitoring of liquidation efficiency
  • Asset historical average discount of 5.6 bps over three months; larger discounts could reduce effective LB and prevent liquidations
  • 96% of weETH borrowing occurs in E-Mode, concentrating risk in specific collateral configurations

Simple Summary

A proposal to adjust weETH’s LTV, LT, and LB on the Ethereum Core instance.

Motivation

weETH’s collateral parameters are currently set to 72.5%, 75%, and 7.5% for LTV, LT, and LB, respectively, on Ethereum — Core. Following observations of user behavior and on-chain liquidity, we are able to recommend adjusting these parameters to make the asset more efficient as collateral. The vast majority of debt against weETH is WETH, making these positions low-risk due to weETH’s utilization of the ETH/USD oracle augmented with its exchange rate.

Additionally, as displayed above, 96% of borrowing is done in E-Mode, relying on different collateral values.

weETH has remained highly liquid against USDT, the top uncorrelated debt asset on Ethereum, indicating that liquidations of uncorrelated positions could be efficiently liquidated.

Our simulations, which take into account on-chain liquidity and user behavior and distribution, indicate that the protocol can increase LTV and LT for weETH, along with decreasing its LB. We recommend maintaining the 2.5 percentage point buffer between LTV and LT.

When reducing LB, it is also critical to note that the asset has not experienced significant depegs from its exchange rate value relative to ETH; its average discount over the last three months was just 5.6 bps. Large discounts can reduce the effective LB and prevent liquidations from being processed.
