## What happened

Sky Core GovOps proposed reducing the Capital Ratio Requirement for Osero's Ethereum SparkLend USDS instance from 100% to 25%.

## What changed

If approved, the instance's required capital buffer would fall by 75 percentage points, permitting greater reliance on Sky-supplied capital relative to Osero capital.

## What did not change

The cached record does not establish ratification, an executive payload, execution, or the resulting live exposure. Other instance and protocol parameters were not shown as changing.

## Confirmed

- The current stated Capital Ratio Requirement is 100%.
- The proposed requirement is 25%.
- The proposal was triggered for the weekly Atlas-edit process.
- The same proposal also documents a 5% tolerance for maximum-exposure overruns caused solely by accrued interest.

## Still open

- The final governance outcome and effective Atlas text.
- The risk analysis supporting the reduction.
- The instance's live exposure, Osero capital, and post-change loss-allocation profile.
- Whether a coordinated on-chain spell was required or executed.

## What it means for an advisor

- Review the Sky backing and allocator-risk assessment if the reduction becomes operative.
- Verify the final capital ratio, instance exposure, and loss-allocation mechanics before incorporating the change into the memo.
- Do not treat the proposal as evidence that Osero or SparkLend is approved.
