How a lending loop stacks yield through deposit-borrow-redeposit cycles, with the real APY math and the liquidation risk laid out plainly.
A lending loop is a DeFi strategy where you deposit collateral, borrow against it, redeposit the borrowed asset, and repeat the cycle to amplify your exposure or yield. People also call it looping or recursive lending. They mean the same thing.
Under the marketing, a lending loop is leverage. You are using lending markets like Aave or Morpho to build a bigger position than your starting capital would allow. Each turn of the loop stacks a little more yield on top, and a little more risk underneath.
That trade-off is the whole story. This guide walks the exact deposit-borrow-redeposit cycle, shows the yield math and the liquidation math side by side, and explains how to unwind a loop before a market drop does it for you.
A lending loop is a way to squeeze more yield or more directional exposure out of the same starting capital by cycling through a lending market. You supply an asset as collateral, borrow against it, put the borrowed asset back to work as collateral, then borrow again.
The words change but the mechanism does not. Looping and recursive lending both describe this deposit-borrow-redeposit cycle.
Here is the part the marketing pages tend to soften. A lending loop is leverage. You end up controlling far more of an asset than you deposited, which is great when it rises and painful when it falls.
The canonical version uses staked or liquid-staked ETH. You supply it, borrow ETH or a stablecoin, convert back, and redeposit to earn staking yield on a larger balance. To picture it, follow the four-stage cycle in the diagram below before the numbers get involved. If you want the deeper primer on the collateral itself, start with liquid staking.
One full loop is easier to follow than the abstract idea. Say you hold 1 ETH worth of liquid-staked ETH. You supply it to a lending market as collateral.
Next you borrow against it. With a conservative loan-to-value, you might borrow 0.7 ETH worth of a stablecoin or ETH itself. You swap or convert that borrowed amount back into the same collateral asset. Then you redeposit it.
That is one loop. Your supplied balance is now 1.7 ETH worth, and your borrowed balance is 0.7 ETH worth. Run the cycle again and both balances climb. Supply grows, debt grows, and your yield-earning base grows with them.
The loop cannot run forever. Loan-to-value (LTV) is the cap. Each protocol only lets you borrow a fraction of your collateral value, so every loop borrows a smaller slice than the last. The numbers converge toward a ceiling instead of exploding to infinity.
There are two ways to build the position. Manual looping means clicking through each supply-borrow-redeposit step yourself, paying gas each time. One-transaction looping uses a flash loan to assemble the whole stack in a single transaction, which saves gas and slippage.
The mechanics matter because they explain where the risk hides. Every loop raises your debt relative to your collateral, and that ratio is exactly what decides whether you stay solvent. Keep that in mind. The next section shows why anyone accepts the trade.
Looping only makes sense if the numbers work out. The engine is the carry spread. You earn supply APR plus any rewards on your collateral, and you pay borrow APR on your debt. When what you earn beats what you pay, the gap is profit.
A small spread does not sound like much. But looping multiplies it across a larger position, so the effective yield on your original capital rises with each loop.
The worked example below assumes a 4% net collateral yield and a 2.5% borrow cost, which leaves a 1.5% raw spread per unit borrowed. It shows how that compounds as you add loops.
| Loops on 1 ETH of capital | Approximate effective APY |
|---|---|
| No loops (plain deposit) | 4.0% |
| 1 loop | 5.0% |
| 3 loops | 6.5% |
| 5 loops (aggressive) | 7.5% |
Those numbers are illustrative, not a promise. Rates move constantly, and the spread can vanish or flip negative overnight.
The catch is symmetry. The same multiplier that lifts your yield also magnifies a drop in your collateral value. A 5x-looped position feels the market move roughly five times as hard. That is why the yield math and the liquidation math are two sides of one coin.
The honest answer to “is this just leverage” is yes. A lending loop is leverage built out of lending primitives instead of a margin account or a perpetual contract. You reach the same place, higher exposure than your capital, by a different road.
The difference is in the plumbing. Spot leverage on an exchange uses a margin account with a liquidation price. A perp uses a synthetic position priced against an index, and you pay or receive a funding rate every few hours. A loop uses real deposits and real borrows, and you pay a borrow rate that floats with market utilization.
Those cost structures behave differently. Funding on perpetual futures can swing hard and flip sign with sentiment. A loop’s borrow rate is usually steadier, though it spikes when everyone borrows the same asset at once.
So why do some traders prefer looping? A few reasons show up again and again.
If you want the wider map of leveraged instruments and how they compare, the crypto derivatives primer sets the context. Looping is one route among several, and knowing the alternatives helps you pick the right tool.
A lending loop concentrates several risks that a plain deposit avoids entirely. They do not hit with equal force, so it helps to know which one usually ends positions first.
Health factor is the number that decides everything. It measures how far your collateral value sits above your debt, and once it drops below 1, the protocol liquidates you and sells your collateral at a penalty.
More loops push the health factor lower because debt climbs relative to collateral. As DL News reported, a conservative 1-2x loop might only liquidate on a roughly 60% collateral drop, while an aggressive stack can liquidate on a much smaller dip. The tighter you loop, the less room a bad candle leaves you.
Your spread depends on borrow APR staying below your collateral yield. When borrowing demand surges, borrow rates can spike above what you earn. Then the loop bleeds money every block until you unwind or the rate settles.
Loops built on liquid staking tokens or stablecoins assume the collateral tracks its reference asset. If a staked ETH token or a stablecoin depegs, the ratio between your collateral and debt breaks, and a liquidation can trigger even when the underlying asset barely moved.
Every extra protocol in the loop is another surface for a bug or exploit. Lending markets, the collateral token, and any automation layer all carry code risk that stacks with each moving part.
Because looping is fundamentally a bet on collateral holding its value, understanding what backs the position is essential. The collateral and margin explainer digs into how that backing actually works.
Getting out of a loop is the reverse of building it, and doing it in the wrong order is how people get caught. The goal is to shrink debt faster than collateral so your health factor rises as you go.
The unwind cycle runs like this:
Each partial repayment lifts the health factor, which buys you breathing room before the next step. That is why you deleverage in stages instead of all at once.
There is a one-transaction option too. A flash loan can unwind the whole stack in a single transaction, repaying all debt and returning your collateral without you juggling steps or gas.
Timing matters more than most people expect. Unwinding during sharp volatility is dangerous, because prices move against you between steps and a thin health factor can cross the line mid-exit. Trim your loops before the storm, not during it. And check for leftover dust, since small unrepaid balances can keep a position technically open.
Whether a lending loop is worth it depends almost entirely on how hard you push it. Conservative looping at 1-2x adds a modest yield bump while leaving real room before liquidation. Aggressive looping chases a bigger number and hands most of your safety margin to the market.
The points meta muddies the picture. Many protocols advertise eye-watering APYs that lean heavily on token incentives rather than durable carry. Treat any headline yield built on points as a temporary campaign, not a reliable rate, and ask what the number looks like once the rewards dry up.
A simple gut-check cuts through the noise. If a 20-30% drop in your collateral would liquidate you, you are over-looped. Full stop. Size the loop so an ordinary market wobble does not end your position.
This is not financial advice, just a frame for deciding. Looping is a leveraged form of yield farming, and the same rule applies to both. The strategies that survive are the ones you can hold through a bad week, not the ones that only work in a calm one.
A lending loop is not safe in the way a plain deposit is. It is leverage, so it carries liquidation risk, interest-rate risk, and smart-contract risk that a simple supply position avoids. A conservative 1-2x loop is far more forgiving than an aggressive one, but no loop is risk-free.
There is no universal number, but most cautious users stay at 1-3 loops so a normal market drop cannot liquidate them. The right count depends on your collateral’s volatility and the liquidation threshold. If a 20-30% collateral drop would wipe you out, you have looped too many times.
Looping is a specific way to create leverage using lending markets rather than a margin account or a perpetual contract. All looping is leverage, but not all leverage is looping. The mechanism differs, but the effect, controlling more of an asset than you deposited, is the same.
Yes, you can be liquidated when looping a stablecoin, mainly if the stablecoin depegs from its reference value. A stablecoin loop feels low-risk because prices barely move, but a depeg breaks the collateral-to-debt ratio and can trigger liquidation even in a calm market.
People loop staked ETH to earn staking yield on a larger balance than their capital alone would allow. The staked ETH keeps earning while it sits as collateral, so the loop stacks staking rewards on top of the leveraged position, often with extra protocol points on top.
Before you build a single loop, get the groundwork right so the strategy does not surprise you.
