Looping & Leverage Deep Dive

Deep dive on looping and leverage — how looping changes exposure, how CR maps to leverage, and the main failure modes to understand

This page expands the mechanics behind loop strategies (leveraged CDP positions): what “leverage” means inside a Trove, how it relates to CR, and what usually breaks first in real usage.

Not investment advice — Looping increases leverage and liquidation risk. This page is educational and focuses on mechanics and failure modes.

At a glance

• A loop is: mint USDHN → swap to collateral → add collateral → repeat.

• Looping increases your gross collateral exposure but also increases your debt.

• The key safety metric is still Collateral Ratio (CR), but it helps to also think in equity and leverage terms.

• Real outcomes depend on fees, interest, slippage, oracle pricing, and USDHN market price.

What “looping” means (precisely)

In Hann Finance, “looping” usually refers to building a leveraged Trove by repeating:

1. mint USDHN against collateral

2. swap USDHN into more of the collateral (or a collateral wrapper)

3. add the collateral back into the same Trove

You end up with:

• more collateral posted

• more USDHN debt owed

• a lower CR buffer than a non-levered Trove (all else equal)

Equity and leverage inside a Trove

We can define three values in USD terms:

• V = collateral value (USD)

• D = debt value (USDHN, plus any accrued interest/fees)

• E = equity (USD) ≈ V - D (a simplified view)

Then a simple “leverage” definition is:

$$L = \frac{V}{E}$$

Interpretation:

• L = 1.0x means “no leverage” (no debt).

• L = 2.0x means “$2 of collateral exposure per $1 of equity” (roughly).

Important simplification — The equality E ≈ V - D is a mental model. It assumes USDHN is valued at ~$1 and ignores liquidation penalties, swap fees, interest growth, and oracle vs market differences.

CR ↔ leverage (useful conversion)

CR is:

$$CR = \frac{V}{D}$$

Using the simplified equity model above:

$$L = \frac{V}{V - D} = \frac{1}{1 - \frac{D}{V}} = \frac{1}{1 - \frac{1}{CR}} = \frac{CR}{CR - 1}$$

So, lower CR implies higher leverage.

Quick table (illustrative)

CR	Approx leverage L = CR/(CR-1)
300% = 3.0	1.5x
200% = 2.0	2.0x
150% = 1.5	3.0x

This table is not a recommendation. It only shows the math relationship.

How looping changes “distance to liquidation”

Liquidation happens when your Trove’s CR drops below the branch minimum (often called MCR, shown in the official UI).

If your current CR is CR_now, and the branch minimum is MCR, then a simple way to think about liquidation price distance is:

$$P_{liq} \approx P_{now} \times \frac{MCR}{CR_{now}}$$

Meaning:

• if CR_now is only slightly above MCR, then P_liq is close to the current price

• looping usually reduces CR_now, making P_liq closer

The three common flows (lever up / lever down / close)

Flow A — Lever up (loop)

High-level:

1. open or start from a Trove with collateral

2. mint USDHN (keeping a CR buffer)

3. swap USDHN → collateral

4. add collateral to the Trove

5. repeat until you reach your target CR/leverage

One-click tools (Zappers) can bundle the steps, but they do not change the underlying mechanics.

Flow B — Lever down (deleverage)

High-level:

1. withdraw or use a portion of collateral (if allowed)

2. swap collateral → USDHN

3. repay USDHN debt

4. re-check CR and repeat until risk is acceptable

Flow C — Close the Trove

To close:

1. repay all USDHN debt (including any accrued interest/fees)

2. withdraw collateral and close

Key reality: if you swapped away the USDHN you minted earlier, you must obtain USDHN again later to repay.

Worked example (numbers, but simplified)

Assume:

• initial deposit: collateral worth $1,000

• you aim to end at CR = 200% = 2.0

• ignore swap fees, interest, and price impact

• treat USDHN as $1.00

From the leverage conversion:

• CR = 2.0 corresponds to L = 2.0x

So your end state is approximately:

• collateral value V ≈ $2,000

• debt D = V/CR ≈ $2,000/2 = $1,000 (≈ 1,000 USDHN)

• equity E ≈ V - D ≈ $1,000

If the collateral price drops 20%:

• V ≈ $1,600

• D ≈ $1,000 (unchanged in units)

• CR ≈ 160%

Whether that liquidates depends on the branch’s MCR. That’s why looped positions are sensitive to small moves.

Repayment cost can change even if CR math looks stable

If you owe 1,000 USDHN:

• if USDHN trades at $1.02, repaying costs about $1,020

• if USDHN trades at $0.98, repaying costs about $980

Looping usually increases debt size, which increases your sensitivity to USDHN market price when you unwind.

Failure modes (what usually breaks first)

Liquidation risk (primary)

• Looping reduces your CR buffer.

• Interest/fees can increase debt over time, slowly pushing CR down even if collateral price is flat.

Guardrails:

• keep a conservative CR

• watch collateral volatility and oracle update cadence

• deleverage early rather than “at the last moment”

Execution risk (swaps + routing)

Exit friction (LSTs and wrappers)

USDHN peg risk

Practical checklist (non-numeric)

• Know your unwind path before you loop: “How do I get USDHN to repay?”

• Treat the UI liquidation price as a risk indicator, not a goal.

• Assume you may need to deleverage fast in a drawdown.

• If you use automation, first understand the manual flow and start small.
