How Crypto Lending Works: Collateral, LTV Ratios, and the Risks Most Guides Skip

Crypto lending allows you to borrow cash or stablecoins by pledging cryptocurrency as collateral, without selling your holdings or undergoing a credit check. You receive a loan based on a loan-to-value (LTV) ratio, typically 30% to 60%, and repay with interest to reclaim your collateral. The IRS generally treats loan origination as non-taxable under Notice 2014-21, but forced liquidation of collateral after a margin call is a taxable event.

Crypto lending lets you borrow dollars or stablecoins against your bitcoin or ether without selling a single satoshi. You pledge crypto as collateral, receive a loan at a set loan-to-value (LTV) ratio, and repay with interest to reclaim your assets. No credit check, no tax return, no pay stub. The trade-off is a set of risks most first-time borrowers do not see coming: collateral liquidation during a market crash, platform bankruptcy swallowing your deposited bitcoin, and surprise tax bills from forced sales you never authorized.

In brief

• Crypto-backed loans are overcollateralized: you must pledge more crypto value than you borrow, typically at 30% to 60% LTV.
• A sharp drop in collateral value triggers a margin call; if unmet within hours, the platform liquidates your crypto at market price.
• Custodial platforms hold your private keys: in bankruptcy, your collateral may become an unsecured creditor claim, not your property.
• Taking the loan is generally not taxable under IRS Notice 2014-21, but forced liquidation of collateral likely is a taxable event.
• DeFi protocols replace platform custody with smart contract code, trading counterparty risk for smart contract vulnerability.

What Crypto Lending Actually Is (and What It Is Not)

Crypto lending, in its simplest form, is borrowing money using cryptocurrency as collateral. You lock up bitcoin, ether, or another accepted asset with a lender, and in return you receive US dollars or stablecoins like USDC. You repay the loan over a set term or on an open-ended basis, with interest, and once repaid, your collateral is released back to you.

The defining feature is overcollateralization. Because crypto prices swing sharply, lenders demand that you pledge more value than you borrow. A 50% LTV ratio means a $20,000 bitcoin deposit secures a $10,000 loan. This cushion protects the lender: if bitcoin drops 25%, there is still enough collateral value to cover the outstanding balance.

Crypto lending has nothing to do with peer-to-peer lending or credit-based personal loans. Lenders do not pull your FICO score, request bank statements, or verify employment. The collateral alone underwrites the transaction. This is why the Consumer Financial Protection Bureau (CFPB) has flagged crypto-backed lending as an area where consumers may misunderstand the risks, particularly around liquidation mechanics and custody arrangements, according to its consumer tools portal updated through 2025.

What crypto lending is not: it is not a margin trading account, though the liquidation mechanics resemble one. It is not a way to avoid taxes on crypto gains permanently. And it is not insured by the FDIC, SIPC, or any federal backstop. If the platform fails, there is no government guarantee waiting to make you whole.

Borrowing against crypto vs. earning yield on crypto

The single biggest source of confusion among readers is the difference between borrowing against crypto and depositing crypto to earn yield. They are opposite sides of the same balance sheet.

When you borrow, you pledge your crypto as collateral and receive cash. You pay interest to the platform. Your crypto sits idle as security; it does not generate yield while locked. When you lend or deposit into a yield account, you are the one providing liquidity. You send your crypto to a platform that lends it out to borrowers or deploys it in DeFi strategies, and you receive a portion of the interest. The IRS treats yield earnings as ordinary income in the year received, per the general principle that crypto received as compensation or reward is taxable at fair market value.

These two activities carry different risk profiles. A borrower's primary risk is collateral liquidation. A yield depositor's risk is platform default or smart contract failure that wipes out the principal. Some platforms offer both services under one roof, which can blur the distinction. Read the terms: if you are earning a stated APY on your deposit, you are a lender, not a borrower, and your funds are likely being re-lent or deployed elsewhere.

Centralized platforms vs. DeFi protocols: the structural difference

All crypto lending falls into one of two architectural models.

Centralized finance (CeFi) platforms operate like traditional online lenders. A company holds your collateral in its custody, manages the loan on its internal ledger, and you interact through a web interface or mobile app. You must complete identity verification (KYC). The platform sets interest rates, LTV limits, and liquidation thresholds. Examples include several major US-accessible platforms that require state-level lending licenses.

Decentralized finance (DeFi) protocols replace the company with code. You connect a self-custody wallet like MetaMask to a protocol such as Aave or Compound, deposit collateral into a smart contract, and borrow against it. No account, no KYC, no customer support line. The smart contract enforces the loan terms automatically: if your collateral ratio falls below the liquidation threshold, anyone can trigger liquidation and earn a small reward for doing so. The protocol itself cannot go bankrupt in the traditional sense, but its smart contract can contain bugs, be exploited, or be governed by a small group of token holders whose decisions may not align with your interests.

How the Loan Mechanics Work Step by Step

A crypto-backed loan follows a predictable lifecycle. Understanding each stage, and the math that drives it, is the difference between using the product intelligently and being blindsided by a liquidation notice at 3 a.m.

This section walks through the entire process using a concrete numerical scenario. The dollar amounts are illustrative, chosen to make the mechanics transparent. Real platform terms vary, sometimes significantly, so the numbers here serve as a thinking tool, not a quote.

Loan-to-value ratio: what it means and how it moves

The loan-to-value ratio measures how much you borrow relative to the dollar value of your collateral. A $20,000 bitcoin deposit with a $10,000 loan means 50% LTV: you borrowed half the collateral's value.

LTV moves constantly because crypto prices move constantly. If bitcoin drops from $20,000 to $15,000, your collateral is now worth $15,000 while your loan remains $10,000. LTV jumps from 50% to 66.7%. The lender's cushion shrinks from $10,000 to $5,000.

Each platform sets two critical LTV thresholds: the origination LTV, the maximum at which it will issue the loan, often 50% to 60%. The liquidation LTV, the point at which the platform can seize and sell your collateral, often 75% to 85%. The gap between them is your margin of safety.

If bitcoin instead rises, LTV falls. At $30,000 per bitcoin, your $20,000 deposit is now worth $30,000 against a $10,000 loan: 33% LTV. You can borrow more against the appreciated collateral or simply enjoy a wider safety buffer.

The margin call trigger: a step-by-step scenario

Take a concrete scenario. A borrower deposits one bitcoin worth $30,000 on a platform offering 50% maximum LTV with an 80% liquidation threshold. The borrower takes a $15,000 loan.

Initial state: collateral $30,000, loan $15,000, LTV 50%. Liquidation would trigger at 80% LTV, which means the collateral must stay above $18,750 ($15,000 divided by 0.80). The safety cushion is $11,250, or a 37.5% drop in bitcoin's price.

Now bitcoin falls to $22,000. Collateral value: $22,000. LTV: 68.2%. Still safe, but the cushion has shrunk to $3,250. The platform may send a warning, but no action is required yet.

Bitcoin drops further to $19,000. Collateral value: $19,000. LTV: 78.9%. The platform issues a margin call. The borrower now has a narrow window, sometimes as short as a few hours, to either deposit additional collateral, or repay part of the loan principal, enough to bring LTV back below the liquidation threshold.

If bitcoin hits $18,700, LTV crosses 80%. The liquidation engine activates. The borrower no longer has a choice.

Liquidation: what happens to your collateral if you don't act

Once LTV breaches the liquidation threshold, the platform sells enough collateral at the prevailing market price to restore a safe LTV ratio. The borrower does not authorize this sale. It is automatic and contractual.

The typical liquidation process: the platform sells a portion of the collateral, often at a slight discount to market price via an internal auction or on-chain liquidation mechanism, uses the proceeds to repay part of the loan, applies a liquidation penalty, usually 5% to 15% of the liquidated amount, and returns any remaining collateral to the borrower.

In the scenario above, if bitcoin hits $18,500, the platform might liquidate 0.2 BTC from the 1 BTC collateral to bring LTV back to a safe level. The borrower receives roughly 0.8 BTC back after the loan is settled, plus a liquidation fee deducted from the proceeds.

This is the moment where tax consequences crystallize. The platform sold your bitcoin. Even though you never clicked "sell," the IRS views this as a disposition of property. If you bought that bitcoin at $10,000 and the platform sold it at $18,500, you realize an $8,500 capital gain per coin, taxable in the year of liquidation.

A common mistake: borrowers track their LTV when markets are calm, then go on vacation or stop monitoring during a volatile week. A 20% intraday drop with a starting LTV of 65% can breach an 80% liquidation threshold in a single candle. Miss the margin call notification, and the platform liquidates before you even see the email.

Custody Risk: The Danger Most Borrowers Underestimate

Many borrowers focus obsessively on LTV ratios and interest rates while ignoring the single biggest risk: the platform holding their collateral might disappear overnight. Several major centralized crypto lenders collapsed in 2022, and borrowers who had pledged bitcoin as collateral discovered a brutal legal reality. Their coins were not held in segregated trust accounts. They were treated as general assets of the bankruptcy estate.

This section explains why custody matters more than rate, and what you can ask before depositing a single satoshi.

Custodial (CeFi) platforms: who actually holds your bitcoin

When you pledge bitcoin to a centralized (CeFi) lending platform, you transfer it to an address controlled by that company. The private keys are theirs, not yours. Your loan agreement likely grants the platform broad rights: to hold the collateral in pooled wallets, to rehypothecate it, meaning lend it out to generate revenue, or to commingle it with other customer assets.

In bankruptcy, the legal question is whether your collateral belongs to you or to the platform's creditors. Under Chapter 11 of the US Bankruptcy Code, assets that are property of the debtor's estate are available to satisfy creditor claims. If the loan agreement treats your collateral as a secured loan with proper segregation, you may have a stronger claim. If the agreement allows commingling and rehypothecation, as many do, your bitcoin may simply be another unsecured creditor claim, recoverable at cents on the dollar after years of litigation.

The 2022 collapses of Celsius, Voyager, and BlockFi illustrated this risk in real time. Borrowers with outstanding loans found themselves in bankruptcy proceedings, uncertain whether their collateral would be returned, netted against their loan balance, or pooled with general assets. The outcomes varied by platform and by the specific terms each borrower had agreed to.

Non-custodial (DeFi) protocols: smart contract risk instead

Non-custodial DeFi protocols like Aave and Compound solve the custody problem by removing the intermediary. Your collateral is not held by a company with employees and a bankruptcy attorney. It is locked in a smart contract, a self-executing piece of code deployed on a public blockchain like Ethereum.

The smart contract holds funds according to rules that anyone can inspect on-chain. Liquidation conditions, interest rate models, and collateral factors are all visible in the code. No CEO can decide to freeze withdrawals, and no bankruptcy court can reclassify your deposit.

But this model introduces a different risk: code vulnerability. If the smart contract contains a bug, an attacker can drain funds. If the protocol relies on an oracle to fetch price data and that oracle is manipulated, the liquidation engine can be triggered incorrectly. Several DeFi protocols have lost hundreds of millions of dollars to exploits, flash loan attacks, and oracle manipulation.

The risk is technical, not institutional. Your collateral cannot be seized in bankruptcy, but it can vanish in a well-crafted exploit. Audits by reputable firms like Trail of Bits or OpenZeppelin reduce this risk but do not eliminate it. An audited smart contract still operates in a permissionless environment where new attack vectors emerge regularly.

What to ask before pledging collateral: a practical checklist

Before pledging crypto as collateral, get written or publicly documented answers to these questions. If a platform cannot answer them clearly, that silence itself is information.

• Custody structure: Are customer collateral assets held in segregated accounts, or are they commingled with platform operating funds? Does the platform rehypothecate collateral?
• Insolvency treatment: What happens to pledged collateral if the platform files for bankruptcy? Is there a legal opinion or public disclosure on this point?
• Insurance: Does the platform carry any insurance covering customer collateral against theft, hack, or internal fraud? What are the coverage limits and exclusions?
• Jurisdiction and licensing: Where is the platform incorporated, and what lending licenses does it hold? State-level lending regulation varies widely; a platform operating from an offshore jurisdiction may offer no US consumer protections.
• Withdrawal terms: Are there lock-up periods, withdrawal delays, or gates? Can the platform unilaterally suspend collateral withdrawals during market stress?
• Audit history: For DeFi protocols, have smart contracts been audited, by whom, and when was the last audit? For CeFi platforms, are proof-of-reserves or attestation reports published regularly?

Tax Implications of Crypto Loans in the US

Tax treatment of crypto loans is one of the most misunderstood topics in the space. The IRS has provided guidance, but gaps remain. This section explains what is known, what is uncertain, and where the tax liability hides.

For a deeper dive into the rules, see our dedicated article on crypto loan tax rules for US borrowers.

Borrowing against crypto: why it is not a sale (generally)

The IRS has stated clearly, since Notice 2014-21, that virtual currency is treated as property for federal tax purposes. Receiving a loan against property is not a sale or exchange. No gain is realized, no loss is recognized. The borrower simply takes on a debt obligation.

This means the moment you receive $10,000 in USDC against your bitcoin collateral, you have not triggered a taxable event. Your cost basis in the bitcoin remains unchanged. There is nothing to report on Form 8949 or Schedule D at loan origination.

Repaying the loan with fiat currency, such as wiring dollars from your bank account, also does not create a taxable event. Your collateral is simply released.

However, repaying the loan using cryptocurrency, either the same asset or a different one, likely constitutes a disposition. Selling bitcoin to raise dollars for repayment triggers capital gain or loss. Using bitcoin directly to repay a loan denominated in dollars is treated as a sale at fair market value. The tax obligation attaches to the repayment method, not the loan structure.

Forced liquidation: the taxable event borrowers forget to plan for

This is the tax trap most borrowers fail to anticipate.

If the platform liquidates your collateral after a margin call, the IRS treats this as a taxable disposition of property. The platform sold your bitcoin at the prevailing market price. You realize a capital gain equal to the sale price minus your cost basis. If you held the bitcoin for more than one year, the gain is long-term and taxed at preferential rates, 0%, 15%, or 20% depending on your income. If held for one year or less, it is short-term, taxed as ordinary income.

This creates a painful scenario: you borrowed against your bitcoin, the market dropped, the platform liquidated 0.3 BTC to cover the margin call, and now you owe capital gains tax on a sale you never initiated, using cash you no longer have, because that cash went to repay the loan and cover the liquidation penalty.

The IRS does not excuse forced sales from taxation. The fact that the sale was involuntary does not change its character as a disposition of property. Taxpayers who fail to report liquidation proceeds on Form 8949 risk underpayment penalties and interest.

Revenue Ruling 2023-14, while not directly addressing lending liquidations, confirmed the IRS's consistent position that crypto transactions are taxable events when value is realized or exchanged. Forced liquidation fits squarely within this framework.

Yield accounts vs. loans: different tax treatment

The tax treatment of borrowing against crypto differs sharply from the treatment of depositing crypto into a yield account.

When you deposit bitcoin or stablecoins into a platform's interest-bearing account, you typically receive periodic payments in crypto. These payments are taxable as ordinary income in the year received, based on the fair market value on the date of receipt. The platform may issue a Form 1099-MISC or similar information return, though compliance is inconsistent across the industry.

When you borrow against crypto, you pay interest. That interest is generally not deductible unless the loan proceeds are used for a business or investment purpose that qualifies under the Internal Revenue Code. Using a crypto loan to buy a car, pay personal expenses, or fund a vacation does not generate deductible interest.

The distinction matters at tax time. A borrower with a $20,000 loan at 9% APR pays roughly $1,800 in interest over a year, none of it deductible for personal use. A yield depositor with $20,000 earning 5% APY reports $1,000 of ordinary income, taxable at marginal rates. Same capital, opposite tax profiles.

DeFi Lending vs. Centralized Platforms: Key Trade-offs

Choosing between a centralized platform and a DeFi protocol is not about which is better in the abstract. It is about which risks you can tolerate and which protections you value.

Both models serve the same core function, letting you borrow against crypto without selling it, but they differ fundamentally in who controls your assets, how transparent the operation is, and what recourse you have if something goes wrong.

Transparency and on-chain auditability in DeFi

DeFi protocols operate on public blockchains. Every deposit, every loan origination, every liquidation is recorded on-chain and verifiable by anyone with a block explorer. You can audit the protocol's total collateral, total borrows, bad debt, and liquidation history in real time.

The smart contract code is open source. Anyone can inspect the liquidation logic, the interest rate model, and the collateral factors. If a parameter change is proposed through governance, the proposal and its potential effects are visible before execution.

This transparency has practical value. You can verify that a protocol is solvent without trusting a company's attestation. You can simulate what happens to your position under various price scenarios by reading the code or using on-chain analytics tools like DeFiLlama or Dune Analytics.

The trade-off is complexity. Reading a smart contract requires technical skill most borrowers do not have. Relying on audit reports from third-party firms bridges some of this gap, but an audit is a point-in-time assessment, not an ongoing guarantee. Exploits have occurred in audited protocols.

For borrowers who want to understand the mechanics without relying on a company's promises, DeFi offers an audit trail that CeFi cannot match. For borrowers who prefer a customer support ticket over a block explorer, CeFi remains the practical choice.

Regulatory uncertainty and consumer protections in CeFi

Centralized platforms operate in a gray regulatory zone. Crypto lending is not banking. Platforms do not hold FDIC insurance, are not supervised by the Federal Reserve for safety and soundness, and are not subject to the Bank Secrecy Act in the same way depository institutions are. However, they must comply with state money transmitter licensing requirements, federal anti-money-laundering rules enforced by FinCEN, and in some cases, state lending licenses.

The SEC has signaled, through enforcement actions against several crypto lending platforms, that certain lending products may constitute securities offerings subject to registration requirements. The CFPB has authority to investigate unfair, deceptive, or abusive acts or practices in consumer financial products, including crypto lending, as outlined on its consumer tools portal.

What does this mean in practice? A CeFi platform may offer a complaints process, a terms-of-service agreement governed by US law, and a corporate entity you can sue. These are real consumer protections compared to DeFi, where there is no corporate defendant and no regulator to call. But they are weaker protections than those governing a bank loan or a brokerage margin account.

DeFi protocols exist largely outside this framework. There is no entity to license, no customer service department, and no US court with clear jurisdiction over a decentralized autonomous organization (DAO). When a DeFi protocol fails, the recourse is zero unless law enforcement identifies and prosecutes an attacker, which is rare and slow.

Borrowers who want regulatory fallback protections should favor CeFi, with the understanding that those protections are thinner than they appear. Borrowers comfortable with code-as-law and zero intermediary risk may prefer DeFi. Our article on crypto loans without collateral covers an adjacent set of lending models with their own risk profiles.

Is Crypto Lending Right for You? Honest Risk Assessment

Crypto lending is a financial tool, not a life philosophy. It makes sense in specific situations and is reckless in others. The following assessment is not advice. Only you, with your financial advisor and tax professional, can determine whether it fits your circumstances.

What follows is a framework for thinking clearly about the decision.

Four risks to weigh before pledging your crypto

Bien que les prêts garantis par des cryptomonnaies ne soient pas des prêts peer-to-peer au sens traditionnel, il existe des options pour ceux qui se demandent comment obtenir un prêt peer-to-peer sur Bitcoin.

Crypto-backed borrowing concentrates four distinct risks that do not exist in a conventional cash loan.

• Volatility risk: Bitcoin can drop 30% in a week. Your LTV can breach the liquidation threshold in hours. A loan that looked safe at 50% LTV on Monday can be liquidated by Thursday. This is not a theoretical concern; it has happened repeatedly during crypto market corrections.
• Liquidity risk: Meeting a margin call requires having cash or additional crypto ready to deploy. If your wealth is concentrated in the same asset that is declining, you may have nothing liquid to add. Borrowers who pledge their entire stack with no cash reserve are one sharp move away from forced liquidation.
• Platform and custody risk: As detailed in the custody section above, a CeFi platform failure can convert your collateral into a bankruptcy claim. A DeFi smart contract exploit can drain your deposit. Neither scenario is covered by FDIC or SIPC insurance.
• Regulatory risk: US crypto regulation is in flux. A platform operating legally today may face enforcement action, asset freezes, or mandatory shutdown tomorrow. The SEC's expanding interpretation of securities laws, the CFPB's growing interest in crypto consumer products, and state-level licensing changes all introduce uncertainty that does not exist in traditional bank lending.

Questions to ask yourself before taking a crypto-backed loan

Before taking a crypto-backed loan, answer these questions honestly. If any answer gives you pause, reconsider the transaction.

• Why am I borrowing? Borrowing against a volatile asset to fund consumption, vacations, cars, or lifestyle expenses puts your long-term holdings at risk for short-term wants. Borrowing to bridge a temporary cash need while avoiding a taxable sale of appreciated crypto has a clearer rationale.
• Can I meet a margin call at 3 a.m.? Crypto markets trade 24/7. Margin calls can arrive on a Saturday night during a flash crash. Do you have liquid funds, stablecoins or cash, accessible within hours? Have you set price alerts and do you check them?
• What is my tax exposure if I get liquidated? Calculate the capital gain on your pledged collateral: current market price minus your cost basis. If that number is large and the gain is short-term, a liquidation could create a tax bill worth a significant fraction of the lost collateral.
• Do I understand where my collateral sits? If CeFi, who holds the keys and what happens in bankruptcy? If DeFi, has the smart contract been audited, and do I understand the oracle mechanism that feeds price data into the liquidation engine?
