Your dashboard has a new row this morning: Looped stETH — up to 6% APY. Two lines down, plain stETH staking pays 2.9%. It's the same token. The difference is that somebody borrowed against it, and now the protocol is offering to let you do the same with three clicks. If your first reaction was "so… can I just do that?", you're exactly who this article is for.
Liquid staking looping — deposit stETH on a lending market like Aave, borrow ETH against it, swap that ETH back into stETH, deposit again — is DeFi's oldest yield multiplier. It's also the strategy that quietly liquidated a chunk of its users in June 2022, and the subject of a 2024 Imperial College London study that found it amplifies precisely the risks its dashboards don't display. You'll leave with three numbers you can compute yourself: the net APY your loop will actually earn (one formula, and the borrow rate decides everything), the exact ETH price at which your position gets liquidated, and the market conditions under which the whole structure unwinds on you. No spreadsheet required by the end.
TL;DR. Looping multiplies both sides of your balance sheet. Net APY = staking yield + (staking yield − borrow rate) × (leverage − 1). At 3% staking and 2% borrowing, 2x/3x/4x earns roughly 4%/5%/6% — but if the borrow rate climbs 2 points above staking, the same loops earn 2%/1%/0%. At a $3,000 ETH entry and an 80% liquidation threshold, liquidation lands near $1,875 (2x), $2,500 (3x) and $2,813 (4x). That 4x buffer is thinner than stETH's June 2022 depeg. Sane defaults: stay at or below 2–2.5x, set a health-factor alert, and write your unwind plan before you deposit.
The loop in plain English — and why 4x is the hard ceiling
Say you start with $10,000 of ETH and swap it into stETH, the staking receipt from Lido that keeps earning the ~2.9% consensus-layer rate while you hold it. You deposit it on Aave's Ethereum market ($12.8B in TVL, the deepest lending venue — SparkLend at ~$4.9B is the main alternative) and borrow ETH against it. Then you swap that borrowed ETH into more stETH and deposit it too. Each pass adds collateral and debt in the same breath, pushing your loan-to-value toward the market's maximum. The ceiling comes from arithmetic: max leverage = 1 ÷ (1 − max LTV). At Aave's 75% max LTV for wstETH, that's 4x — no amount of cleverness loops past it, because the last borrow can't exceed the collateral it's borrowed against.
| Target leverage | Your equity | Total collateral | Total debt | Effective LTV |
|---|---|---|---|---|
| 1x (just staked) | $10,000 | $10,000 | $0 | 0% |
| 2x | $10,000 | $20,000 | $10,000 | 50% |
| 3x | $10,000 | $30,000 | $20,000 | 66.7% |
| 4x (max at 75% LTV) | $10,000 | $40,000 | $30,000 | 75% |
Notice what the table hides: every pass costs gas, every swap pays a spread, and every dollar of debt accrues interest from day one. The machine is built. Now for the only question that matters — what does it earn?
The net APY math: the spread is the whole game
Here is the entire strategy compressed into one line: Net APY = staking yield + (staking yield − borrow rate) × (leverage − 1). Everything rides on the term in parentheses — the spread between what your stETH earns and what your debt costs. Lido's 30-day stETH APY has recently run in a 2.5–4% band, around 2.9% typical; Aave's ETH variable borrow rate has fluctuated roughly 2–4% with utilization. Run the optimistic case first: 3% staking, 2% borrowing, a +1 point spread. At 3x, that's $30,000 of collateral earning $900 a year, minus $20,000 of debt costing $400 — $500 on your $10,000, or 5% net. The leverage did exactly what the formula said.
| Leverage | Net APY at +1pp spread (3% stake, 2% borrow) | Net APY at −1pp spread (3% stake, 4% borrow) |
|---|---|---|
| 1x | 3.0% | 3.0% |
| 2x | 4.0% | 2.0% |
| 3x | 5.0% | 1.0% |
| 4x | 6.0% | 0.0% |
Look at the right-hand column. A negative spread doesn't get diluted by leverage — it gets amplified, with no floor. The borrow rate is set by utilization, which you don't control and can't forecast; a positive spread today is a promise the market can revoke tomorrow. That's the trade: you've doubled your sensitivity to a number someone else sets. (If all you want is staking exposure plus points and rewards without debt, LST yield stacking gets you some of the upside with none of the liquidation math.) And which receipt you loop matters too — Lido vs Rocket Pool is a liquidity-and-fee decision that shows up directly in your spread.
Your liquidation price, worked out to the dollar
This is the number the dashboard won't show you. Liquidation hits when your collateral (valued at the live price, times the market's liquidation threshold) no longer covers your debt. Solve for the price and you get: liquidation price = entry price × (debt ÷ collateral) ÷ liquidation threshold. Assume you entered at ETH = $3,000 and use Aave's 80% liquidation threshold for ETH-correlated collateral — the market has historically set it around 80–83%, so 80% is the conservative pick. Positions opened a few points below max LTV earn a little extra room; these are the clean, fully-built numbers.
| Leverage | Debt ÷ collateral | Liquidation ETH price | Drop from $3,000 entry |
|---|---|---|---|
| 2x | 0.50 | ~$1,875 | −37.5% |
| 3x | 0.667 | ~$2,500 | −16.7% |
| 4x | 0.75 | ~$2,813 | −6.25% |
Now put those buffers next to history. In June 2022, stETH traded roughly 6–7% below its ETH peg at the trough. A 4x position's entire buffer is 6.25% — the depeg alone puts it at the edge, before ETH itself moves a cent, and ETH has fallen more than 60% within months in past cycles. Even 3x's 16.7% buffer is one bad week. This is why experienced loopers run 2–2.5x: drop from 3x to 2.5x (debt ÷ collateral of 0.60) and liquidation moves to about $2,250, a 25% cushion — barely less yield, dramatically more survivability.
When looping blows up: the data from 442 real positions
The most rigorous answer comes from a 2024 Imperial College London study (arXiv:2401.08610) that reconstructed 442 leverage-staking positions on Ethereum over 963 days — 537,123 ETH, about $877M at the time. The honest headline: 81.7% of positions beat plain Lido staking on APR. Looping works, most of the time, in calm markets. But the same paper's stress tests show looping amplifies cascading liquidation risk and contagion when stETH devalues, with the Terra crash as the worked example. The mechanism is circular: prices dip → positions deleverage → everyone sells stETH and repays debt at once → utilization spikes, so borrow rates jump exactly when holders least afford them → thinner buffers liquidate, selling further into the dislocation. stETH traded ~6–7% under peg at the 2022 trough partly because of exactly this unwind. Our primers on DeFi liquidation cascades and depeg risk cover both halves of that loop.
| Market condition | Illustrative ETH borrow rate | Net APY at 3x (3% staking) |
|---|---|---|
| Calm (utilization ~45%) | ~2% | +5.0% |
| Busy (utilization rising) | ~4% | +1.0% |
| Stress (mass deleveraging) | 6%+ | −3.0% or worse |
Those borrow rates are illustrative, not live quotes — the point is the shape, not the decimals. In the stress row you're paying for the privilege of holding leveraged stETH through its worst week, and unwinding into it costs gas, spread and slippage on top. The strategy doesn't fail randomly; it fails precisely when it's crowded, and it's always most crowded at the bottom.

Frequently asked questions
What is liquid staking looping?
Liquid staking looping is depositing a liquid staking token such as stETH as collateral on a lending market like Aave, borrowing ETH against it, swapping that ETH back into stETH, and depositing it again. Each pass raises your total staked exposure, and the loop converges to a maximum leverage of 1 ÷ (1 − max LTV) — 4x at Aave's 75% max LTV for wstETH.
What net APY does liquid staking looping actually deliver?
Net APY = staking yield + (staking yield − borrow rate) × (leverage − 1). With staking at 3% and borrowing at 2% (a +1pp spread), 2x/3x/4x leverage earns about 4%/5%/6%. If the borrow rate rises to 4% (a −1pp spread), the same loops earn only 2%/1%/0%. The spread, not the leverage, decides the outcome.
What is the liquidation price of a looped stETH position?
Liquidation price = entry price × (debt ÷ collateral) ÷ liquidation threshold. At a $3,000 ETH entry with an 80% liquidation threshold, a 2x loop liquidates near $1,875 (37.5% below entry), 3x near $2,500 (16.7% below), and 4x near $2,813 (only 6.25% below). Opened slightly below max LTV, positions gain a few percent of extra room.
What leverage is safe for looping stETH?
No leverage is safe, but 4x is structurally fragile: its 6.25% price buffer is thinner than the roughly 6–7% discount stETH traded at during the June 2022 depeg. Real positions typically run 2–3x, and staying at or below 2–2.5x with a health-factor alert around 1.5 is the closest thing to a sane default. This is educational content, not financial advice.
What happened to looped stETH positions in June 2022?
After the Terra collapse, stETH traded roughly 6–7% below its ETH peg at the trough. Loopers who needed to unwind had to sell stETH into thin liquidity, deepening the dislocation, while borrow rates spiked as utilization jumped exactly when everyone deleveraged at once. A 2024 Imperial College London study of 442 leverage-staking positions (537,123 ETH, about $877M) found looping amplifies cascading liquidation risk and contagion during stETH devaluation.

If you loop, two habits pay for themselves: check the ETH borrow rate and recompute net APY weekly (it takes a minute with the formula above), and keep effective leverage at or below 2–2.5x with a health-factor alert around 1.5. Looping doesn't manufacture yield — it manufactures exposure; the APY is just the exposure wearing a nicer number.
