Silo Finance — Weekly Risk Report (Week 3)

This report provides a structured weekly risk review of lending markets on Silo Finance. The objective is to identify pools with elevated liquidation, oracle, and liquidity risk under stressed market conditions.

Markets are divided into two segments:

Section A: Core Pools (> $100K collateral deposits)

Section B: Long-Tail Pools (< $100K collateral deposits)

For week 3 we’ll take into account only Section A pools

Risk labeling excludes smart contract exploit risk and focuses on market structure, liquidity depth, oracle design, and liquidation viability.

High Risk Pools — Detailed Breakdown

Pool 181 — siUSD / USDC

Key Observations

  • Total siUSD DEX liquidity: ~$3.5M
  • Total siUSD used as collateral: ~$6.4M
  • Documented siUSD depeg history
  • Collateral size exceeds reliable exit liquidity

Primary Risk Drivers

  • Liquidation cascade risk under stress conditions
  • siUSD depeg → liquidation failure → bad debt formation
  • Potential death spiral scenario if:
    • price deviates,
    • liquidation incentives are insufficient,
    • gas costs spike simultaneously

Failure Mode

If siUSD depegs and liquidators cannot exit positions profitably due to shallow liquidity and execution costs, liquidations stall and protocol bad debt accumulates.

Suggested Actions

  • Increase siUSD DEX liquidity depth
  • Reduce siUSD deposit cap
  • Temporarily reduce mLTV to ~80% until liquidity and stability metrics improve

Pool 168 — siUSD / USDC

Key Observations

  • siUSD collateral exposure remains elevated
  • Known historical depeg behavior

Primary Risk Drivers

  • Same structural exposure as Pool 181
  • Liquidation cascade and death spiral dynamics
  • Liquidity vs collateral imbalance risk

Suggested Actions

  • Increase siUSD liquidity depth
  • Reduce deposit caps
  • Lower mLTV to ~80% until stabilization

Pool 141 — reUSD / USDC

Key Observations (Week 1 – week 2)

  • reUSD DEX liquidity (Avalanche): ~$1.4M
  • reUSD collateral deposited: ~$1.4M
  • Oracle-dependent valuation

Primary Risk Drivers

  • Oracle freshness dependency
  • Liquidity depth insufficient vs collateral
  • Stablecoin-style peg fragility risk

Failure Mode (Detected in week 1 – 2)

Oracle lag + liquidity gap → liquidation slippage → bad debt risk.

Status: Capital at risk largely removed

  • -99% TVL change → Pool declassified

Pool 121 — savBTC / BTC.b

Key Observations

  • savBTC DEX liquidity: < $100K
  • savBTC collateral deposited: ~$1.7M
  • Custom oracle pricing

Primary Risk Drivers

  • Extremely low exit liquidity
  • Custom oracle trust assumptions
  • Depeg and death spiral risk profile

Failure Mode

Collateral cannot be liquidated at scale → liquidations fail → systemic bad debt.

Suggested Actions

  • Freeze market temporarily
  • Reopen only after:
    • liquidity depth improves materially
    • oracle robustness is validated

Pool 161 — PGOLD / PUSD

Key Observations

  • Chainlink oracle tracks XAU forex price
  • Collateral asset = PGOLD token
  • Oracle tracks reference asset, not token market price

Primary Risk Drivers

  • Oracle/reference mismatch risk
  • Peg trust assumption between PGOLD and XAU
  • Token-specific deviation risk not captured by oracle

Failure Mode

If PGOLD deviates from gold price while oracle tracks XAU, protocol may overvalue collateral → bad debt risk.

Suggested Actions

  • Validate peg mechanism transparency
  • Add token-specific pricing safeguards
  • Consider haircut or reduced mLTV

Pool 184 — hgETH / ETH

Key Observations

  • Vault-based asset used as collateral
  • Oracle relies on NAV valuation
  • NAV potentially manipulable depending on vault mechanics

Primary Risk Drivers

  • NAV manipulation risk
  • Oracle reliability concerns
  • Valuation attack surface

Failure Mode

Inflated NAV → overvalued collateral → under-liquidated positions → protocol bad debt.

Suggested Actions

  • Freeze market until valuation methodology is fully verified
  • Require hardened oracle design
  • Add conservative valuation buffers

Pool 162 — sUSDp / USDC

Key Observations

  • Custom oracle
  • Thin secondary market liquidity

Primary Risk Drivers

  • Oracle reliability concerns
  • Liquidity depth risk

Suggested Actions

  • Require hardened oracle design
  • Increase liquidity depth on secondary markets

Highly inefficient Pools

Pool 158 and 172 — PT tokens 19/02/2026 expiry date

Key Observations

  • PT-sUSDai (19 Feb 2026) expired
  • PT-iUSD (19 Feb) expired
  • TVL reduced but sill highly inefficient

Suggested actions

  • Update pools ID: 158 and 172 with newest PT collateral

Pool 185 agETH/ ETH

Key Observations

  • $1M unused ETH
  • $10 worth of collateral deposited
