Failure mode: borrow APR spikes (utilization shock) while PT implied yield compresses → carry turns negative, you de-lever into bad liquidity. ##### B) Liquidation is driven by oracle + LLTV/LT, not “fundamentals”[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=6 "Edit section: B) Liquidation is driven by oracle + LLTV/LT, not “fundamentals”") Even if PT “should” converge, your position lives/dies by the money market’s collateral valuation rule. * Morpho Blue: liquidation eligibility is when LTV > LLTV, and health factor is computed directly from collateral value, debt, and LLTV. Morpho Docs[[3]](https://freemwiki.com/index.php?mobileaction=toggle_view_mobile&title=Openai%2F6973721c-28b0-8007-a991-09211709d274&veaction=edit#cite_note-3) * Euler: liquidation is triggered when risk-adjusted collateral value < debt, and can happen due to price moves or debt growth. Euler Docs[[4]](https://freemwiki.com/index.php?mobileaction=toggle_view_mobile&title=Openai%2F6973721c-28b0-8007-a991-09211709d274&veaction=edit#cite_note-4) Key economic risk: oracle design (spot vs smoothed vs PT-specific risk oracle). If the oracle can be pulled by secondary-market dislocations, you can be liquidated even though “maturity value” is fine. ##### C) “Liquidity gap” risk (the silent killer)[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=7 "Edit section: C) “Liquidity gap” risk (the silent killer)") Liquidators must sell seized PT somewhere (or hedge it). If the PT market is thin / out of range / stressed, liquidation execution can fail or clear at huge discounts → bad debt risk for the market and forced liquidation losses for you. This is explicitly called out in PT risk discussions for money markets.

Pendle contracts (tokenization + redemption flow) 2. the underlying yield-bearing token / protocol (LST/LRT, stable yield token, etc.) A failure in either can reprice PT sharply and instantly. docs.pendle.finance[[6]](https://freemwiki.com/index.php?mobileaction=toggle_view_mobile&title=Openai%2F6973721c-28b0-8007-a991-09211709d274&veaction=edit#cite_note-6) ##### F) Reflexivity + “loop convexity”[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=10 "Edit section: F) Reflexivity + “loop convexity”") Looping makes your liquidation distance nonlinear: * small adverse move → higher LTV * higher LTV → less buffer * any further move → liquidation cascade This is why “2–3x is fine, beyond that gets hairy” is a common heuristic in PT looping guides. Medium[[7]](https://freemwiki.com/index.php?mobileaction=toggle_view_mobile&title=Openai%2F6973721c-28b0-8007-a991-09211709d274&veaction=edit#cite_note-7) #### 2) “Optimal LTV” calculation (practical framework)[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=11 "Edit section: 2) “Optimal LTV” calculation (practical framework)") There isn’t one universal optimum because it depends on: * oracle type + update frequency * liquidation bonus / close factor / auction mechanics * PT liquidity + slippage under stress * your rebalance frequency (do you monitor hourly, daily, weekly?) * borrow rate volatility (util shock probability) So the right way is: choose an acceptable liquidation probability over a horizon and back out a safe LTV. ##### Step 1 — Define variables (per market)[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=12 "Edit section: Step 1 — Define variables (per market)") * LLTV (Morpho) or LT (Euler equivalent trigger) * h = risk horizon (e.g., 1 day if you monitor actively; 7 days if you want “sleep well”) * σ = volatility of collateral value in loan terms (PT priced in borrowed asset) * r_b = borrow APR (use a stressed value, not today’s) * LB = liquidation bonus / penalty (how much collateral you lose when liquidated) * s = stress slippage haircut for unwinds (PT liquidity + DEX depth) * z = quantile (e.g., 2.33 for 99%, 3.09 for 99.9%) ##### Step 2 — Compute a conservative “survival buffer”[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=13 "Edit section: Step 2 — Compute a conservative “survival buffer”") Two things push LTV up over horizon h: 1. collateral value can drop 2. debt grows via interest A simple (usable) bound: * Collateral shock factor: q=exp⁡(−z⋅σh)q = \exp(-z \cdot \sigma \sqrt{h})q=exp(−z⋅σh​) * Debt growth factor: g=exp⁡(rb⋅h)g = \exp(r_b \cdot h)g=exp(rb​⋅h) * Execution haircut for liquidation mechanics + slippage (rule of thumb): η=1−(LB+s)\eta = 1 - (LB + s)η=1−(LB+s) (If LB=7% and you assume 5% slippage in stress, η≈0.88\eta \approx 0.88η≈0.88) ##### Step 3 — Safe initial LTV[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=14 "Edit section: Step 3 — Safe initial LTV") For Morpho Blue, you want to stay below LLTV even after shocks: LTV0,max⁡≈LLTV⋅qg⋅η\textbf{LTV}_{0,\max} \approx LLTV \cdot \frac{q}{g} \cdot \etaLTV0,max​≈LLTV⋅gq​⋅η This gives you an LTV that has roughly “(1 − tail probability)” chance of staying solvent over horizon h, under your σ/r assumptions, and acknowledges that liquidation is lossy. #### 3) Translating LTV into “how many loops” (quick)[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=15 "Edit section: 3) Translating LTV into “how many loops” (quick)") If you loop by borrowing and buying more PT repeatedly, leverage roughly scales like: Leverage≈11−LTV\text{Leverage} \approx \frac{1}{1-\text{LTV}}Leverage≈1−LTV1​ So: * LTV 0.70 → ~3.33x gross exposure * LTV 0.80 → 5x * LTV 0.85 → 6.67x This is why tiny LTV changes massively change liquidation fragility. #### 4) What I need from you to compute your optimal LTV numbers (no fluff)[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=16 "Edit section: 4) What I need from you to compute your optimal LTV numbers (no fluff)") Send: 1. Which PT (e.g., PT-sUSDe-YYYYMMDD) and chain 2. Borrow asset (USDC? DAI? ETH?) 3. Market + parameters (Morpho: LLTV + oracle type; Euler: LT / risk params if shown) 4. Your desired monitoring horizon: 1d / 3d / 7d 5. Your stress assumptions (or I’ll apply defaults): - σ (daily vol of PT/borrow) - stressed borrow APR (e.g., 2× current or p95) If you don’t want to pull vol data, I can still give you a parameterized LTV curve (LTV as a function of σ and horizon) so you can plug numbers in instantly. ##### Default “founder-safe” settings (if you want an immediate starting point)[edit](https://freemwiki.com/index.php?title=Openai/6973721c-28b0-8007-a991-09211709d274&action=edit§ion=17 "Edit section: Default “founder-safe” settings (if you want an immediate starting point)") Without your specifics, a conservative institutional heuristic is: * target liquidation probability ≤ 0.1% over 7d * assume stressed borrow APR = 2× current * assume stress slippage 5–10% on PT * then set LTV 10–20 points below LLTV/LT for looping (bigger buffer if oracle is spot-like) This aligns with how PT-as-collateral risk is discussed: liquidation execution + oracle behavior dominate outcomes, not the “it converges at maturity” story.
