Deleveraging in DeFi: What It Means and How to Handle It

Educational content only, not financial, investment, tax, or legal advice. DeFi and borrowing involve risk, including loss of capital. Income and appreciation are not guaranteed.

Geometric illustration of debt being reduced

Picture a Sunday night. You borrowed against your ETH months ago, and over time the loan crept up to around 70% of your collateral’s value. Then the market drops 15% while you’re at your kid’s soccer game. By Monday morning, either you chose to shrink your loan, or a bot did it for you at a discount. That’s deleveraging in DeFi, and the difference between those two outcomes is mostly preparation.

In plain terms, deleveraging is reducing the debt you carry against your crypto. You can do it on purpose by repaying a loan or adding collateral. Or the protocol does it to you through liquidation. This guide covers both, what sets them off, and what we’d do before the market gives us a vote.

TL;DR

Deleveraging means reducing borrowed money relative to what you hold. In DeFi it’s either voluntary (you repay or add collateral) or forced (a liquidator repays part of your debt and takes your collateral at a discount).
Forced deleveraging is the expensive kind. Research on liquidation designs finds borrowers can end up giving up more collateral than needed.
When many positions get forced down at once, prices can fall further and trigger more liquidations. Regulators flag this as a systemic risk.
Your best defense is a lower loan-to-value ratio, a written plan for what you’ll repay first, and alerts that fire before your health factor gets thin.
Deleveraging isn’t good or bad by itself. It’s a tool, and timing decides which one it turns out to be.

What deleveraging means in DeFi

Borrowing to hold more exposure than your own cash would allow is what finance people call leverage. Think of a mortgage: you put down some of your own money and the bank covers the rest. Deleveraging is paying that mortgage down.

In DeFi, the loan works a little differently. There’s no credit check. Instead, you lock up crypto as collateral and borrow against it. Academic work on liquidations notes that DeFi loans are usually over-collateralized, meaning you deposit more value than you borrow, and that borrowing is what makes leverage possible in the first place.

Two flavors matter for you:

Borrowing to spend or earn. You borrow stablecoins against BTC or ETH to fund life or put the cash to work, and you keep your coins. Your debt is modest relative to your collateral, and your main job is not getting liquidated.
Looping for bigger exposure. You borrow, buy more of the same asset, deposit it, and borrow again. That’s explicit leverage, and it’s where deleveraging tools get used most.

If you’re newer to the first flavor, our guide on how to stress-test your loan-to-value is a good companion to this one.

Voluntary deleveraging: reducing your own risk

This is the version you control, and it’s the one we want you using. Some protocols even build it into a single transaction.

Exactly’s documentation describes a feature where deposited collateral is used to repay debt. Its example takes a 4x position, built from a 100 USDC deposit and a 300 USDC borrow, and brings it down to 1x. In everyday terms: instead of selling your coins and then paying off the loan in two messy steps, the position unwinds in one move.

Curvance’s documentation draws a useful line between two kinds of unwind. A partial deleverage reduces debt and collateral while leaving the position open. A full unwind repays the debt and pulls out as much of the selected collateral as possible.

That gives you three practical moves when risk climbs:

Add collateral. Your debt stays the same, but the cushion gets bigger.
Repay part of the debt. Your cushion stays the same, but the debt shrinks. Apart from network fees, this costs only the cash you use, as long as you already hold the repayment asset and don’t have to sell crypto to get it.
Unwind the position. You close the loop and accept that the strategy is over for now.

Which one fits depends on what you have on hand. If you hold spare stablecoins, repaying is clean. If you only hold more of the volatile asset, adding collateral raises your exposure to the very thing falling. It’s worth knowing that before you need it.

A simple worked example

Say you’ve borrowed against ETH and your loan sits at a 50% loan-to-value ratio. A drop in ETH’s price pushes that ratio up, because your collateral is worth less while your debt hasn’t moved. If your protocol liquidates at, say, 80%, you have room, but not unlimited room. In that hypothetical, ETH would have to fall about 37.5% before you reach 80% (1 − 0.50 ÷ 0.80). A 15% drop only takes you to about 59% (0.50 ÷ 0.85). The exact numbers vary by protocol and asset, so check the one you use.

Now compare two Monday mornings. In the first, you wake up, see the alert, and repay a slice of the loan from savings. You pay a network fee and lose a little time. In the second, you don’t see it, and the protocol handles it for you.

Forced deleveraging: how liquidation does it for you

When a position gets too thin, protocols don’t call you. They let someone else step in.

According to a 2023 OECD working paper on liquidations, a liquidator generally repays part of the underwater debt and receives part of the borrower’s collateral at a discount. The report adds that some systems use auctions, while others use instant liquidation with a predetermined incentive.

So the sequence looks like this:

Your collateral falls, or your debt grows, or both.
Your health factor (a score where below 1 means the position can be liquidated) drops under the line.
A liquidator, usually an automated bot, repays some of your debt.
The bot receives your collateral at a discount as payment.
Your loan is smaller, and so is your collateral. You’ve been deleveraged, and you paid a penalty for it.

That penalty is the point. Think of it like a tow truck: the service works, nobody asked for it, and the bill is yours.

What can trigger it

The OECD lists three drivers: falling collateral value, rising value of the borrowed asset, or higher borrowing interest. Any of them can push your health factor below 1 or your collateral under the protocol’s liquidation ratio.

The third one catches people. A variable interest rate can quietly eat your cushion even when prices are flat. A BIS working paper adds that leverage is driven mainly by loan-to-value requirements, borrowing cost, price movements and market sentiment, which is a decent summary of everything you’d want to watch.

Our crypto loan liquidation guide walks through the mechanics step by step, and the stETH collateral guide covers a case where your collateral and your price risk don’t always move together.

When pools run short: protocol-level deleveraging

Sometimes a conventional sale isn’t possible, because the collateral is hard to sell in size. Marginly’s documentation describes a mechanism for that case. Rather than selling unavailable collateral, the protocol closes the liquidated position against opposing positions and proportionally reduces those positions’ collateral and debt.

The design goal is keeping the system solvent. The tradeoff, which you should know about if you use margin-style protocols, is that other users’ positions can be reduced too. Read how your specific protocol handles shortfalls before you deposit, the same way you’d read a policy before you sign it.

What forced deleveraging costs you

There are two kinds of cost: the one you pay and the one everyone pays.

The cost to you

The 2021 study by Qin and colleagues finds that existing liquidation designs motivate liquidators well but can sell excessive discounted collateral at the borrower’s expense. The OECD working paper raises a similar concern. In other words, the system is built to make sure the bot gets paid, and your outcome is a secondary concern.

That’s not a conspiracy. It’s just incentives. A protocol has to make liquidation attractive enough that someone will do it at 3 a.m. during a crash, and the discount is how it pays for that.

The cost to everyone

When many positions get liquidated together, the selling itself can push prices down. A 2023 OECD working paper analyzed three major lending protocols and found a positive relationship between liquidations and later price volatility in major decentralized-exchange pools.

BIS researchers Lehar and Parlour add that liquidators on some protocols can use flash loans and sell collateral immediately, which produces both temporary and permanent price effects across several exchanges.

The Financial Stability Board puts it in bigger terms. It says leverage has an outsized impact on crypto-market dynamics and that automatic collateral liquidation can make deleveraging in DeFi especially disruptive. It also notes that DeFi lacks the orderly liquidation arrangements and circuit breakers of traditional finance, so fire-sale risk is real.

Here’s the loop that matters for your wallet: prices fall, liquidations fire, liquidators sell, prices fall more, and more positions cross the line. You don’t have to be reckless to get caught in it. You just have to be near the edge when it starts.

How falling prices can trigger cascading liquidations

For context, a BIS working paper covering 2021 to early 2023 reports that overall borrower leverage typically ranges from 1.4 to 1.9 (measured as assets divided by the borrower’s own equity, roughly a 29% to 47% loan-to-value), and that the largest and most active users run higher. Higher leverage also raises the share of debt sitting close to liquidation, which weakens the whole lending market. Staying at the low end isn’t only safer for you. It keeps you out of the part of the curve where trouble starts.

Is deleveraging good or bad?

Honest answer: neither, and it depends on who’s pulling the lever.

Voluntary deleveraging is usually good for the borrower. You’re reducing the chance of a forced sale, you’re lowering interest costs, and you’re buying sleep. The price is that you give up some upside, because less debt means smaller gains in a rally. If your strategy depends on borrowing to fund daily cash flow, some of that cost is worth paying.

Forced deleveraging is usually bad for the borrower. You lose collateral at a discount, you may trigger a taxable event depending on how the position is handled, and you lose the choice of timing.

For the market, it cuts both ways. Debt that’s been worked down makes lending systems sturdier. A violent wave of liquidations does the opposite in the short run. How far that stress could spread beyond crypto markets is uncertain, so we’d treat any past episode as a snapshot, not a guarantee for the future.

And a reality check from us: we can’t predict when the next wave comes, and anyone who says they can is selling something.

A deleveraging plan you can write down today

The best time to decide how you’ll deleverage is when nothing is happening. Here’s the version we’d put on a single page.

Set your lines before the market does

Pick a ceiling for loan-to-value. Choose a number well below your protocol’s liquidation threshold, and treat it as a trigger to act, not a target to hold.
Decide the order of moves. For example: repay with stablecoins first, add collateral second, partial unwind third. Having the order written down keeps panic out of it.
Keep a reserve. Stablecoins parked outside the loan are the cheapest deleveraging tool you can own.

Watch the right numbers

Your health factor is the headline, but interest rates and the price of the borrowed asset matter too. Tracking all of it in one place beats checking five dashboards. Our piece on crypto portfolio tracking for DeFi borrowers covers what to monitor and how often.

Choose collateral with the exit in mind

Collateral that’s deep and liquid is easier to unwind and less likely to hit a shortfall. We cover the tradeoffs in how to choose a collateral asset, and the broader routine in our collateral management guide.

Size positions like a parent, not a gambler

If a liquidation would change what you can do for your family this year, the position is too big. That’s not a financial rule, just a sanity check. For a structured way to size, see how to size BTC and ETH income positions, and for the wider picture, crypto risk management for BTC and ETH holders.

A tax note, since it comes up: repaying a loan with cash isn’t the same as selling crypto, but liquidations and swaps can create taxable events in the US and many other places. The outcome depends on where you live and how the transaction happens, so talk to a qualified tax professional who knows crypto before you build a strategy around any assumption here. Our overview of accessing cash without selling BTC or ETH explains the basics.

FAQ

What does deleveraging mean in simple terms?

It means reducing the amount you owe relative to what you own. In DeFi, that usually looks like repaying part of a crypto-backed loan or adding collateral so the loan is a smaller share of the total. It can also happen to you automatically through liquidation.

What’s the difference between leveraging and deleveraging?

Leveraging means borrowing to hold more exposure than your own money would allow. Deleveraging is the reverse: working that borrowing back down. Exactly’s documentation uses an illustrative example of moving a 4x position (100 USDC deposited, 300 USDC borrowed) down to 1x.

Is deleveraging in DeFi the same as liquidation?

Liquidation is one way deleveraging happens, and it’s the forced, costly way. A liquidator repays part of your debt and takes your collateral at a discount. Deleveraging on your own terms avoids that discount.

How can I avoid being deleveraged by force?

Keep your loan-to-value well below the liquidation line, hold a stablecoin reserve for repayments, and use alerts on your health factor. Check your borrowing rate too, because rising interest can erode your cushion even if prices don’t move.
