# Aave efficiency mode: correlated assets and a narrower risk assumption

Aave Efficiency Mode, or E-mode, applies a selected category’s borrowing permissions and collateral parameters. It can permit more borrowing for certain asset combinations, but it also restricts eligible borrowing. Higher capacity is not protection against a breakdown in the assets’ expected relationship or against liquidation.

## Key facts

- **Category rules:** Each category specifies its own LTV, liquidation threshold and bonus. ([Efficiency Mode](https://aave.com/help/borrowing/e-mode))
- **Borrowing scope:** Borrowing is restricted to the selected category’s permitted assets. ([Efficiency Mode](https://aave.com/help/borrowing/e-mode))
- **Multiple categories:** The retrieved liquid E-mode description permits assets in more than one category. ([Efficiency Mode](https://aave.com/help/borrowing/e-mode))

## More capacity can mean a smaller buffer

Consider hypothetical eligible collateral worth 1,000 and a category liquidation threshold of 95%. Borrowing 900 gives health factor 950 / 900 ≈ 1.056. If collateral value drops to 940 while debt remains 900, the result is 893 / 900 ≈ 0.992.

The assumed 6% relative decline crosses the threshold despite the assets initially being treated as related. These are teaching parameters, not a current market configuration.

## Read permissions for the specific category

Do not infer eligibility from a familiar ticker or from another network’s settings. Review the category’s collateral list, borrowable list and parameters. Existing borrowing can constrain whether a category change is valid.

## Watch the relationship and the total debt

The useful risk question is how the collateral’s value can move relative to what is owed. Interest also increases debt. Check the proposed post-change health factor and the exact selected category rather than treating E-mode as a universal safety setting.

## Questions

### Does E-mode make every supplied asset better collateral?

No. Benefits and permissions are category-specific; assets outside the relevant rules do not automatically receive them.
