# Risk parameters

> The per-market parameters that decide how much you can borrow, when you are liquidated, and how much room sits between the two.

Every borrow market on AGI3 publishes a small set of parameters. Together they decide how much you can borrow against a given collateral, and how far prices can move before your position is liquidated. They are set by the underlying protocol per market, not by you, and they can be changed by that protocol.

## The parameters

| Parameter             | Typical value       | What it controls                                                                    |
| --------------------- | ------------------- | ----------------------------------------------------------------------------------- |
| Max borrowable LTV    | 85%                 | The most you can owe, as a percentage of collateral value, at the moment you borrow |
| Liquidation threshold | 90%                 | The LTV at which your position becomes liquidatable                                 |
| Liquidation buffer    | 5 percentage points | The gap between the two; the room you have after borrowing the maximum              |
| Oracle price          | Per market          | The price the market itself uses to value your position                             |
| Available liquidity   | Varies              | How much of the borrow asset the market can currently lend                          |

## Loan-to-value

Your LTV is the value of what you owe divided by the value of what you have posted:

```
LTV = debt value / collateral value
```

Both sides are valued at the market's own **oracle price**, not at the market price you see quoted elsewhere. This matters: the protocol's solvency check runs against the oracle, so the oracle is the only price that decides whether an action succeeds or a position is liquidatable. A position can look comfortable at market prices and still be refused at oracle prices.

## The liquidation buffer

The two thresholds are separate on purpose.

* Max borrowable LTV is a limit on new borrowing. Ask for more than this and the transaction is refused.
* Liquidation threshold is the point at which your position can be liquidated.

The difference between them is your buffer. With an 85% max LTV and a 90% liquidation threshold, borrowing the absolute maximum leaves you five percentage points of LTV before liquidation. That is a smaller cushion than it sounds, because LTV rises both when collateral falls *and* when interest accrues on your debt.

This buffer is what [health factor](/risk/health-factor) measures. A position at exactly the max borrowable LTV has a health factor of 1.00, and one at the liquidation threshold has 0.00.

## The 3% safety margin

When the platform shows you a maximum borrow amount or a maximum withdrawal, it quotes **97% of the theoretical limit**.

This is deliberate. The protocol re-runs its solvency check at execution time, against the live oracle price and against debt that has accrued interest since you opened the form. A number computed at the theoretical limit would frequently be rejected by the time it reached the chain. The 3% reduction leaves room for that drift.

If you want to borrow the true maximum, expect to do it in stages rather than in one transaction.

## Available liquidity

Separately from your own limits, a market can only lend what it actually holds. If a market's available liquidity is lower than your collateral would otherwise permit, your borrow is capped by liquidity instead. The platform shows you the lower of the two.

The same constraint applies in reverse when you supply: if a market's assets are heavily borrowed, only part of your supply may be withdrawable at that moment. This feeds the liquidity component of your [portfolio health score](/risk/portfolio-health-score).

## Parameters can change

Max LTV, liquidation threshold, and available liquidity are properties of the underlying market. They can be revised by the protocol that operates it, and a revision applies to positions already open: a reduction in the liquidation threshold moves you closer to liquidation without you having done anything. Monitor open positions rather than setting them and leaving them.
