## TL;DR

- A depeg is not a default. A stablecoin briefly trading at $0.87 doesn't mean it failed — but for a leveraged loop, **a temporary pricing event equals a permanent loss of equity**.
- What decides whether a loop survives isn't the final magnitude of the depeg, but the moment it first crosses the liquidation threshold. That moment often requires only **3–6% of deviation**.
- Minimum depeg that triggers liquidation = **(LT − LTV) / LT**. The more aggressive the leverage, the less depeg the position can absorb.
- Different depeg mechanisms have very different speeds and recovery curves. A risk system that only watches "price" cannot tell them apart.

## 1\. An Uncomfortable Fact

In March 2023, after Circle's exposure to Silicon Valley Bank became public, USDC traded down to $0.87.

That was a depeg. But USDC did not fail. Circle's reserves were intact. The market simply repriced bank counterparty risk within 48 hours. Two trading days later, USDC was back at $0.999.

**For an address holding a 10x USDC loop that weekend, the recovery meant nothing**. The position had already been liquidated the moment USDC touched $0.97. USDC came back. The principal did not.

This is the most counterintuitive thing about depegs and leverage: a depeg is not defined by whether the asset eventually recovers. **It is defined by whether you are still there at the bottom**.

## 2\. Leverage Translates Depeg Into Default

Mainstream narratives often conflate depeg and default. In research, they are two distinct event types.

**Default** is structural — reserves run short, contracts fail, the asset disappears. Value is unrecoverable.

**Depeg** is market-driven — at some moment, in some venue, an asset's quoted price diverges from its theoretical value. **Most depegs recover**.

But under leverage, the difference between the two disappears. **Liquidation is based on real-time price, not final price**. Once the moment arrives where your collateral mark-to-market × liquidation threshold \< your debt, you are liquidated — regardless of what happens a second later.

**Without leverage, depeg and default are two different things. At 10x leverage, they are the same thing.**

## 3\. How Big a Depeg Triggers Liquidation?

Let LTV be the maximum loan-to-value the protocol allows, LT be the liquidation threshold, and d be the depeg magnitude on the collateral. When a loop is maxed out, the liquidation condition simplifies to:

> **Minimum depeg triggering liquidation: d > (LT − LTV) / LT**

Plug in typical parameter sets and a sharp stratification appears.

An **aggressive stablecoin pair** with 90% LTV and 93% LT is liquidated by a depeg of just **3.2%**. An **extreme stablecoin loop** (92% LTV / 93% LT) is liquidated by **1.1%**. A typical **LST loop** (85% / 90%) tolerates **5.6%** before liquidation. A **conservative ETH / stablecoin** loop (75% / 85%) needs **11.8%** to be wiped.

This produces a counterintuitive conclusion: **leverage and depeg tolerance are inversely related**.

A 10x stablecoin loop sounds aggressive, but its depeg tolerance is only 3.2%. The March 2023 USDC drop to $0.87 would have liquidated any 10x USDC loop the moment the price touched $0.97 — before the market had time to understand what was happening. A 5x stETH loop sounds safer, but its tolerance is 5.6% — the 7% deviation in June 2022 was enough to wipe out every 5x stETH loop on Aave.

> **Part 1 introduced 1 / (1 − LTV) as the leverage formula — the "front side." (LT − LTV) / LT is its back side — the depeg threshold. Together, the two define the survival boundary of any loop.**

## 4\. Four Mechanisms That Produce Depegs

Different depegs have different speeds, recovery profiles, and signal patterns. Lumping them together obscures the strategic differences that matter.

**Type 1 — Reserve / Counterparty Risk**. The reference case is USDC-SVB in March 2023. The reserve structure itself is intact, but the counterparty holding the reserves is being repriced. Onset within hours; recovery within days (USDC took roughly 3 days). **For a leveraged loop, the damage approaches 100%** — even if the asset recovers, liquidation has already occurred.

**Type 2 — Redemption Queue Stress**. The reference case is stETH-Celsius in June 2022. The asset can theoretically be redeemed 1:1, but the redemption mechanism has time delays — validator exit queues, protocol settlement windows. When redemption isn't immediately available, the secondary market discounts. Slow widening over days to weeks; convergence once the queue clears. Damage to loops is moderate-to-high — discounts erode the health factor over time, **but the reaction window is far longer than in Type 1**.

**Type 3 — Algorithmic / Hedging Mechanism Failure**. The reference case is the UST collapse in May 2022. The peg-maintenance mechanism itself fails under extreme market conditions — algorithmic arbitrage, delta-neutral hedging, reserve rebasing. The failure self-accelerates: depegs trigger redemptions, redemptions trigger more depeg. **This is the only category of depeg events that regularly leads to permanent asset destruction**. Damage to loops approaches total loss regardless of leverage level.

**Type 4 — Oracle / Price Source Divergence**. Different price sources (CEXs, different DEXs, aggregators) quote the same asset at different prices, and the lending protocol's oracle is using a stale or thin-liquidity source. Instantaneous; recovery within minutes — **but not necessarily above your liquidation threshold**. Liquidations from this category are "false liquidations" — the asset has not actually depegged, but your position is already gone.

The key difference among the four is not severity — it is **signal pattern**. Type 1 has counterparty news leading the price. Type 2 has redemption queue metrics. Type 3 shows imbalance in on-chain flows and hedges before the break. Type 4 only appears as cross-venue spread. **A risk system that watches only "price" will miss the early signals from the first three and the false signals from the fourth — simultaneously.**

## 5\. The LST / LRT Exception

Yield-bearing assets like stETH, wstETH, weETH, and ezETH have a structurally unique property in depeg analysis: **their depegs are not continuous drifts. They are step jumps.**

Ordinary stablecoin depegs are usually smooth — the market gradually reprices new risk, and price moves continuously.

LSTs and LRTs behave differently. In normal conditions, their secondary market prices track theoretical value within a few basis points. Then at some moment — a large unstaking request, a validator slashing event, a wave of points farming capital exiting at once — **the main Curve pool tilts instantly, and the price jumps from 1.000 to 0.96 in a single block**.

The impact on loops is non-linear. The frequency of depegs is lower than with stablecoins, but the immediate impact of a single event is larger. **Any strategy that depends on "see deviation, then react" fails on LSTs and LRTs — by the time deviation appears, the reaction window has already closed.**

## 6\. How AllDefi Handles Depeg

Continuing Part 2's three-layer architecture, with the specific variables adjusted for depeg events.

**Layer 1 — Continuous Monitoring**. The system tracks, every block: real-time prices for the collateral asset across multiple liquidity venues, the deviation between price sources, and the rate of change in that deviation (continuous vs. step-jump). **Cross-source price comparison is the core signal for identifying oracle-divergence-type depegs**.

**Layer 2 — Threshold-Tiered Response**. Deviation crosses preset alert threshold (e.g., 0.5%) → halt new loop additions. Deviation continues widening without converging within a reasonable window → actively unwind part of the position. Deviation approaches the pair's liquidation threshold (per the formula in Section 3) → exit fully. Significant divergence appears between price sources → switch execution path to avoid pools that feed the oracle. Each rule is pre-defined. No human decision required in the loop.

**Layer 3 — Execution Optimization**. Unwinding is split across multiple transactions and DEX venues to avoid single-point impact. Execution pace adjusts dynamically based on observed slippage and gas. Deeper pools are preferred even when the path is longer.

In a moderate-severity depeg event, the system typically completes risk reduction within 30 minutes — which is precisely the window where most depeg events still have an open reaction window.

## 7\. Back to the Question

> **How big a depeg wipes out a loop?**

Not 5%. Not 10%. Not any single number.

**It depends on the leverage, the type of depeg mechanism, and how fast the position responds.**

A 10x stablecoin loop liquidates at 3.2% depeg — an event that happened in March 2023, and will happen again. A 5x LST loop is wiped at 5–7% deviation — happened in June 2022, and in several recent LRT incidents. When an algorithmic mechanism breaks, no leverage level and no reaction speed gets you out in time.

Part 1 showed how looping leverage is calculated. Part 2 showed how interest rates can give back the profits. This part shows how a depeg can take the principal in a single moment.

The three reports together form the complete mathematical skeleton of looping risk.

**A skeleton is not a tool. Turning the math into executable real-time risk management is what AllDefi is building.**
