What Is Liquidation in Crypto Lending?
Liquidation is the single biggest risk in crypto borrowing — and the most misunderstood. It's the forced sale of your collateral when its value drops too far. Here's exactly how it works, what it costs, and how to make sure it doesn't happen to you.
Liquidation is the forced sale of your collateral when your loan-to-value (LTV) ratio exceeds the platform's threshold. It protects lenders from bad debt — and it can cost you a significant portion of your deposited crypto.
How common is it? According to data tracked by DefiLlama, DeFi liquidations exceeded $2.18 billion across protocols in 2024 alone. Single-day liquidation events during major crashes have wiped out over $400 million in collateral in under 24 hours.
The key number: Most platforms liquidate between 75% and 90% LTV. If you borrow at 50% LTV, your collateral needs to lose roughly 40–50% of its value before you're at risk — a substantial safety buffer.
What liquidation actually means
When you take a crypto-backed loan, you deposit collateral worth more than the amount you borrow. This over-collateralization is what makes the loan possible without a credit check — the lender's safety net is your crypto, not your credit score.
Liquidation happens when the value of your collateral drops to the point where it no longer provides sufficient coverage for your outstanding loan. At that point, the lending platform — or in DeFi, an automated smart contract — sells some or all of your collateral to repay the debt.
Think of it like a margin call in traditional finance, but faster and often with less warning. In crypto markets, where 20–30% price swings can happen in a single day, the distance between a healthy position and liquidation can close rapidly.
How the liquidation process works
The mechanics follow a predictable sequence, though the speed varies significantly between CeFi and DeFi platforms.
First, the platform continuously monitors the value of your collateral against your outstanding loan. This is expressed as a loan-to-value (LTV) ratio or a "health factor." If you borrowed $10,000 and your collateral is worth $20,000, your LTV is 50%. If your collateral drops to $12,500, your LTV climbs to 80%.
Second, when your LTV approaches the danger zone, most CeFi platforms issue margin calls — notifications urging you to either add more collateral or repay part of your loan. DeFi protocols don't send notifications; your health factor is visible on-chain but it's your responsibility to monitor it.
Third, if your LTV breaches the liquidation threshold and you haven't acted, the liquidation triggers. On CeFi platforms, the company's risk engine initiates the sale. On DeFi protocols, third-party "liquidators" — bots and arbitrageurs — compete to execute the liquidation and earn a bonus for doing so.
The entire process can unfold in minutes on DeFi, or within a few hours on CeFi. During a market crash, thousands of positions can be liquidated simultaneously, creating a cascade effect that pushes prices down further and triggers additional liquidations.
Liquidation thresholds by platform
Each platform sets its own liquidation thresholds, and they vary based on the volatility and liquidity of the collateral asset. Here's how the major platforms compare for Bitcoin collateral as of early 2026:
| Platform | Type | Margin Call | Liquidation LTV | Penalty |
|---|---|---|---|---|
| Nexo | CeFi | 71.4% LTV | 83.3% LTV | Varies |
| Ledn | CeFi | ~70% LTV | ~80% LTV | Market sale |
| Aave v3 | DeFi | No margin call | 86% LTV (BTC) | 5% bonus |
| Compound v3 | DeFi | No margin call | ~83% LTV (BTC) | 5–8% penalty |
| MakerDAO / Sky | DeFi | No margin call | ~77% LTV (ETH) | 13% penalty |
Thresholds change with collateral type
The numbers above apply to Bitcoin or Ethereum collateral. More volatile assets like altcoins have lower liquidation thresholds — often 65–75% LTV — because their prices can swing more dramatically. Always check the specific threshold for your collateral type before borrowing.
How liquidation differs in CeFi vs DeFi
The economic outcome is similar — your collateral gets sold — but the experience is very different depending on where you borrowed.
CeFi liquidation typically gives you a grace period. Platforms like Nexo send email and app notifications when your LTV rises, giving you hours (sometimes up to 72 hours depending on the platform) to add collateral or repay. Some platforms liquidate gradually — selling just enough to bring your LTV back to a safe level rather than closing the entire position.
DeFi liquidation is instant and automated. There are no warnings, no grace periods, and no customer support to negotiate with. When your health factor drops below 1.0 on Aave, any liquidator bot can trigger the sale. The liquidator receives a 5% bonus on the collateral they help sell — this bonus comes from your pocket. DeFi liquidations are also public: anyone can see your position and its health factor on the blockchain.

Liquidation penalties and hidden costs
Losing collateral to liquidation is bad enough, but the real cost is often higher than borrowers expect. Several factors stack against you:
Liquidation penalty: Most platforms charge a fee on top of the debt repayment. On Aave v3, liquidators receive a 5% bonus — meaning 5% more of your collateral is sold than strictly necessary to cover the debt. MakerDAO's penalty is a steep 13%. CeFi platforms are less transparent about penalties but typically sell at market rates with some spread.
Slippage during crashes: Liquidations cluster during market crashes — exactly when liquidity is thinnest. Your collateral may be sold at prices 2–5% below the displayed market price due to slippage, especially for less liquid assets.
Cascade effect: Large-scale liquidations push prices down further, which triggers more liquidations. During the May 2021 crash, over $8 billion in crypto positions were liquidated across exchanges and lending protocols within 48 hours, according to Coinglass data. The selling pressure from liquidations amplified the crash by an estimated 15–20%.
Tax liability: In jurisdictions like the United States, a liquidation is treated as a taxable disposal of your asset. If your Bitcoin appreciated from $30,000 to $80,000 and gets liquidated, you owe capital gains tax on the $50,000 gain — even though you didn't choose to sell.
A real-world liquidation example
Let's walk through a concrete scenario to illustrate how quickly things can escalate.
Starting position: You deposit 1 BTC (worth $90,000) as collateral and borrow $45,000 in USDC. Your starting LTV is 50%.
Price drops 30%: Bitcoin falls to $63,000. Your 1 BTC is now worth $63,000 against a $45,000 loan. Your LTV jumps to 71.4%. On most platforms, you'd receive a margin call here.
Price drops 45%: Bitcoin falls to $49,500. Your LTV is now 90.9%. On a platform with an 83% liquidation threshold, your position was already partially or fully liquidated.
The cost: Assuming a 5% liquidation penalty on a DeFi protocol, approximately $47,250 of your collateral is sold (loan + penalty). You're left with roughly $2,250 in remaining collateral — and a tax bill on the forced sale. From a $90,000 deposit, you kept $45,000 in loan proceeds plus ~$2,250 in leftover collateral. You lost approximately $42,750.

How to avoid liquidation
Liquidation is avoidable in the vast majority of cases. These strategies significantly reduce your risk:
Borrow conservatively. The single most effective protection is starting with a low LTV. At 50% LTV, your collateral needs to lose roughly 40% of its value before you're liquidated (depending on the platform threshold). At 25% LTV, it would need to lose roughly 70%. For Bitcoin — which has historically experienced maximum drawdowns of 50–80% during bear markets — a 50% LTV provides reasonable but not bulletproof coverage. According to Glassnode data, Bitcoin's largest drawdown in the 2022 bear market was approximately 77% from its all-time high.
Set price alerts. Configure notifications at key price levels well above your liquidation price. Most portfolio trackers (CoinGecko, Blockfolio, Delta) let you set custom alerts. Set at least two: one at the margin call level and one 10% above your liquidation price. DeFi users can use services like Tenderly or DeFi Saver for position monitoring.
Keep collateral ready to top up. Have additional crypto or stablecoins accessible so you can add collateral quickly if prices drop. Keeping your entire portfolio locked as collateral with nothing in reserve is a common mistake that turns manageable dips into liquidations.
Use stablecoin collateral where possible. Some platforms allow borrowing with stablecoin collateral, which eliminates price volatility risk entirely. This doesn't apply to most use cases (the point is usually to borrow against volatile assets), but for certain strategies it's a safer option.
Automate protection on DeFi. Tools like DeFi Saver offer automated collateral management — they can automatically add collateral or repay part of your loan when your health factor drops, even when you're not watching. This adds a layer of safety for DeFi positions where there are no margin calls.
Tax implications of liquidation
This is where liquidation adds insult to injury. In the United States, the IRS treats a liquidation as a disposal of property — functionally the same as selling your crypto. If you originally purchased your Bitcoin at $30,000 and it was liquidated at $49,500, you have a taxable gain of $19,500 on top of the loss you've already suffered.
The tax applies even though you didn't voluntarily sell. You had no control over the timing, the price, or whether the sale happened at all. This makes liquidation one of the most tax-inefficient outcomes in crypto.
In some cases, if your collateral was liquidated at a loss (e.g., you bought BTC at $90,000 and it was liquidated at $49,500), you may be able to claim a capital loss — but the rules around crypto wash sales and collateral disposals are still evolving. Consult a tax professional familiar with crypto for your specific situation.

Frequently asked questions
What is liquidation in crypto lending?
Liquidation is the forced sale of your collateral when its value drops below a platform's required threshold. It exists to protect lenders — if your collateral can no longer safely cover your loan, the platform sells enough of it to repay the debt.
At what LTV ratio does liquidation happen?
Most CeFi platforms trigger liquidation between 83% and 90% LTV. DeFi protocols vary — Aave v3 has liquidation thresholds ranging from 75% to 86% depending on the collateral asset. The exact threshold depends on the platform and the type of collateral you've deposited.
Do I lose all my collateral when liquidated?
Not necessarily. In a partial liquidation, only enough collateral is sold to bring your loan back to a safe LTV ratio. However, you'll pay a liquidation penalty (typically 5–15%), so you lose more than just the loan amount. In severe market crashes, full liquidation can occur and you may lose all deposited collateral.
Can I get my collateral back after liquidation?
If the liquidation was partial, the remaining collateral stays in your position and you can withdraw it once your loan health improves. If your position was fully liquidated, the collateral is gone — you keep whatever loan proceeds you received, but the crypto is sold. There's no way to reverse a liquidation.
How can I avoid liquidation on a crypto loan?
The most effective strategies are: borrow at a lower LTV ratio (50% or below gives substantial buffer), set price alerts on your collateral asset, keep additional crypto ready to top up your collateral if prices drop, and avoid volatile or low-liquidity collateral types. Monitoring your loan health ratio regularly is essential.
Is liquidation a taxable event?
In most jurisdictions including the United States, yes. A liquidation is treated as a disposal of your crypto asset, which triggers capital gains or losses. If your collateral appreciated since you acquired it, you'll owe capital gains tax on the difference — on top of losing your collateral.
