Moonwell MIP-X66 Could Cut Bad-Debt Interest 85% on Base

Moonwell’s MIP-X66 governance proposal entered its vote collection period with changes to market risk settings, interest-rate models and protocol reserves aimed at recapitalizing the USDC market. The package could reduce monthly interest on bad debt across seven Base markets from about $338,785 to $50,273, a projected monthly saving of $288,512, or roughly 85%, assuming balances and utilization remain unchanged.

The estimate concerns slower growth in existing debt, not cash returned to suppliers. The Sept. 4 recovery update did not confirm reserve transfers or set a timetable for USDC repayments, while execution status and subsequent USDC transfers remain unverified. The proposal would withdraw only protocol-owned assets on Base and OP Mainnet for conversion to USDC, without directly transferring user funds.

Why it matters

Moonwell is addressing two different problems: reducing the cost of bad debt and restoring liquidity to a market affected by the Aug. 27 MAMO incident. That incident involved inflated collateral accounting and oracle-price manipulation, with Anthias Labs estimating roughly $9.1 million in residual borrower obligations at its Aug. 27 evidence cutoff, including about 2.35 million USDC in remaining borrower debt.

The distinction matters for depositors. A lower interest rate can improve the protocol’s trajectory, but it does not itself create withdrawal liquidity. Suppliers also sought separate figures for market cash, performing and impaired debt, reserves and recoveries, plus a policy for post-incident deposits and fair withdrawals. Moonwell retained Zero Shadow to assist with recovery efforts, but announced no recovered-cash amount or guarantee of full repayment.

Market impact

MIP-X66 could create conditions for Moonwell to consider reopening Base borrowing, but any restart remains subject to further risk assessment. Until the proposal is executed, reserves are transferred and suppliers receive a clear recovery plan, the central market impact remains uncertainty around access to USDC and the value that can ultimately be recovered.
