How a treasury can fund a falling health factor

A treasury facing a falling health factor should first work out how much of the borrowed asset it can repay, then compare that with adding collateral. In lending markets such as Aave, the health factor compares collateral value, adjusted by each asset’s liquidation threshold, with the value of the debt. A fall in collateral prices, a rise in debt value or accrued interest can lower it; below 1, a position becomes eligible for liquidation.

What raises a health factor most directly?

Repaying debt reduces the denominator of the calculation, so it usually improves the health factor more directly than supplying more collateral. The repayment generally has to be in the borrowed token, plus any interest accrued. If the treasury already holds that token, it can repay directly; otherwise, it must source it, for example by selling another liquid treasury asset.

The conversion route affects how much reaches the repayment. A swap can lose value to fees, price impact and slippage, and the resulting token still has to be repaid in a separate transaction unless the route combines those steps. For an overview of four ParaSwap routes for moving and swapping crypto, see the linked guide; the choice of route matters because execution costs reduce the amount available to retire debt.

Adding eligible collateral raises the numerator instead. It can help when the treasury wants to avoid selling an asset, but it leaves the debt in place and ties up more funds in the position. The collateral must be accepted by that market and enabled for collateral use. Its value can also fall, so the improvement may not last.

How should a treasury choose where the funds come from?

Start with a position snapshot: the current health factor, debt tokens and amounts, collateral balances, and the prices and liquidation thresholds the protocol applies. Then set a target buffer above the liquidation boundary, rather than funding only enough to move just above it. There is no universal safe target: volatility, asset correlation, market liquidity and the treasury’s ability to act again all matter.

Next, rank available sources by cost and reliability. A practical order is:

• Use liquid balances of the debt token for a direct repayment.
• Sell a liquid treasury asset for the debt token, allowing for swap costs and execution delay.
• Add eligible collateral if preserving the asset matters more than keeping it liquid.
• Consider a combined repay-with-collateral route only after checking its fees, required approvals and minimum output.

One analogy helps: repaying debt is like lowering the water in a tank, while adding collateral raises the level of the rim. Both increase the gap before the danger line, but the first also reduces what is owed. For most treasuries with debt-token liquidity, a partial repayment is therefore the clearer first move; collateral is a useful alternative when selling would be more costly or strategically undesirable.

What should the treasury check before acting?

Estimate the result before signing. Protocol interfaces may preview the health factor after a repayment or supply, but the figure depends on the market’s current prices and parameters. Check that the transaction uses the correct network, debt asset and account, and that any required token approval is limited to the intended operation. For a swap, review the route, minimum received and slippage setting. If the transaction fails or takes time to confirm, prices can move in the meantime.

A treasury should also keep some working liquidity aside for gas, further repayments and operational needs. Committing every available token to collateral can leave no easy way to respond to another adverse move. Record the position after execution and assign someone to monitor it; a one-off top-up does not stop prices or interest from changing the calculation.

The funding choice changes the balance between debt, collateral and liquid reserves: repayment cuts debt, while a collateral deposit adds backing but locks up assets. The next things to watch are the health factor, debt growth, collateral prices and the cost of converting treasury funds into the borrowed token.
