Yearn OG USDC
Plain-English summary of this vault — what it does, who runs it, where the yield comes from, and what could break it. Generated from the same deterministic inputs shown elsewhere on this page; the numbers are the source, this is just the explanation.
You deposit USDC and Yearn lends it out to borrowers who've posted collateral — mostly OETH (Ethereum staking derivatives), plus smaller positions in stablecoins and Pendle fixed-yield tokens. The lender earns interest from borrowing demand against that collateral; rates are set by supply and demand on Morpho Blue.
Yearn runs this vault with a conservative posture — 81% weight on OETH borrowing, the rest in stablecoin collateral, all on Ethereum.
The 4.26% APY comes from borrowing interest on USDC lent against OETH (utilization 86%) and smaller stablecoin collateral positions; no idle cash and no listed incentive programs.
OETH concentration is the material shape — an 81% allocation to a single staking derivative means depeg or liquidation stress in OETH would directly hit recoveries. Borrowing utilization is also high (85–90% across markets), leaving little buffer if demand drops.
Good fit for an allocator seeking stablecoin yield with minimal complexity (risk score 27, complexity 35) if comfortable with OETH as a primary collateral bet; avoid if OETH liquidity or peg stability concerns you.

Yearn OG vaults lend underlying assets to markets labeled as moderate risk by the Yearn team. Optimization across markets is handled automatically via an algorithm developed by Yearn. Supply caps are set based on various factors and continuously monitored by the Yearn team as well.
Morpho V2 vault — wraps downstream Morpho markets and V1 vaults via adapters.
Some V2 adapters point at Morpho Blue markets directly; their underlying market detail isn't resolvable in the universe-level fetch, so this vault carries a V2 opacity surcharge in the risk model.
What this vault is actually exposed to — including dependencies that are not visible from the strategy name.
Every market the vault has supplied into, with current LTV, LLTV, oracle, and IRM. Idle balances are listed explicitly.
Modeled NAV impact under historical and hypothetical tail events. Each impact = − (shock magnitude) × (vault exposure) × (pass-through). Hover the calculator icon for the per-scenario formula.
March 2023 SVB episode: USDC traded as low as $0.88 before banking exposure was clarified. Mark-to-market loss on 100% of vault TVL (the loan asset is USDC).
V2 vaults route through adapters into downstream venues. A misbehaving adapter (paused, drained, or pointing at a compromised target) can lock or mismark a portion of the vault until governance acts.
Vault has $1M idle buffer (100% of $1M TVL). $49M of the $50M request queues; the redeemer takes a ~0.50% forced-exit discount weighted across collateral mix plus 0-day TVM cost. $49M of the request exceeds the vault's $1M TVL and cannot be redeemed at all.
