# E-Mode

E-Mode is Current’s high-efficiency borrowing mode for correlated assets.

Instead of applying one generic collateral rule across the entire market, Current groups closely related assets into dedicated E-Mode groups. Within each group, users can access elevated LTVs, higher liquidation thresholds, and pair-specific risk parameters designed around the behavior of that asset pair.

This allows users to borrow more efficiently when the supplied and borrowed assets are highly correlated, such as Sui and ui-pegged LSTs, or USD-pegged stablecoin pairs.

### Why E-Mode Matters

Most lending markets apply conservative parameters uniformly at the asset level. This works for general borrowing, but it limits capital efficiency for assets that are naturally correlated.

Current’s E-Mode is designed to unlock higher borrowing capacity where the risk profile supports it.

For example, borrowing between Sui and Sui-pegged LSTs carries a different risk profile from borrowing between unrelated volatile assets. The same applies to USD-pegged stablecoins. By separating these relationships into dedicated E-Mode groups, Current can offer higher capital efficiency without applying the same risk assumptions to the entire market.

### Isolated E-Mode Positions

Each E-Mode position on Current is isolated from the user’s main lending position and from other E-Mode positions.

* Each E-Mode group has its own collateral and debt position.
* Risk is calculated independently for each E-Mode position.
* Parameters are applied at the pair/group level, not globally.
* Users can manage different E-Mode strategies separately.

### Current E-Mode Groups

Current supports multiple E-Mode groups across the Main Market and other isolated markets.

{% hint style="info" %}
**Some E-Mode groups on Current are directional**.

This means that two assets may have different E-Mode configurations depending on the borrowing direction. For example, `USDC → USDsui` and `USDsui → USDC` can exist as separate E-Mode groups, each with its own parameters.

This design allows Current to set more precise risk controls for each direction of exposure, instead of assuming both directions carry the same risk.

### Risk Parameters

E-Mode does not mean risk-free borrowing. It means higher efficiency under stricter, group-specific assumptions.

Each E-Mode group can have its own:

* Maximum LTV
* Liquidation threshold
* Borrow cap
* Supply cap
* Oracle configuration
* Risk monitoring rules

These parameters are calibrated based on asset correlation, liquidity depth, oracle reliability, volatility, and market structure.

Current also monitors E-Mode borrow exposure as part of its risk system.
