What Is a Bitcoin-Backed Loan? How to Borrow Against BTC Without Selling
Key Takeaways
- •Bitcoin-backed loans let holders borrow U.S. dollars or stablecoins against pledged BTC, usually at loan-to-value ratios of 30% to 70%, while keeping their market exposure and often avoiding capital gains tax.
- •Borrowers face margin calls and liquidation when falling Bitcoin prices push loan-to-value ratios higher, making volatility the central risk of the product.
- •The sector has rebounded since the 2022 Celsius and BlockFi bankruptcies, with centralized lending more than tripling from its late-2023 low and total crypto-backed loan volume reaching $56.16 billion in Q2 2026.
- •In February 2026, Ledn closed a $188 million Bitcoin-backed securitization whose $160 million senior class received a preliminary BBB- rating from S&P Global, described by SVB as the first investment-grade rating for a Bitcoin-collateralized lending portfolio.
- •Published rates as of October 2026 run from about 5.8% at Coinbase to roughly 14% at Unchained, and fees such as origination, prepayment and liquidation charges can push effective costs above headline rates.
Bitcoin-backed loans let holders pledge BTC as collateral to borrow U.S. dollars or stablecoins, preserving exposure to Bitcoin's price and often avoiding a taxable sale.
Loan-to-value ratios typically run from about 30% to 70%, and borrowers face margin calls or liquidation if Bitcoin's price falls sharply. The market has matured considerably since the 2022 lender collapses, with an investment-grade securitization completed and major banks joining the field, though published rates still run from roughly 5.8% to 14%.
Most long-term Bitcoin holders know the problem. Cash is needed for a house deposit, a business or a tax bill, but selling BTC means giving up exposure to its future price, and in many countries it also triggers capital gains tax. A Bitcoin-backed loan offers a way around that: pledge the Bitcoin as collateral and borrow dollars or stablecoins against it.
The concept is as old as lending itself. People have long borrowed against homes, stock portfolios and gold. What is new is the collateral: an asset that trades around the clock and can swing in price by double digits within a single week.
The market collapsed in 2022, when lenders including Celsius and BlockFi went bankrupt. It has since returned in a more cautious form, with centralized lending more than tripling from its late-2023 low, according to Galaxy Research.
This guide explains what Bitcoin-backed loans are, how they work, who offers them, and the risks borrowers should understand before taking one out.
What Is a Bitcoin-Backed Loan?
A Bitcoin-backed loan is a secured loan that uses BTC as collateral. The borrower deposits Bitcoin with a lender or locks it in a smart contract, and in return receives a loan worth a fraction of that Bitcoin's value, paid out in fiat currency such as U.S. dollars or in a stablecoin such as USDC.
The Bitcoin stays locked while the loan is open. Once the borrower repays the principal plus interest, the collateral is returned.
Because lenders rely on the collateral rather than a borrower's income history, many of these loans require little or no traditional credit check. They come in two broad types:
- Centralized (CeFi) loans, offered by companies such as Ledn, Strike, Unchained, Nexo and Coinbase. Borrowers pass identity checks, and the company or its custodian holds the BTC.
- Decentralized (DeFi) loans, offered by protocols such as Aave and Morpho. A smart contract holds the collateral, and native BTC usually has to be "wrapped" into a token on another blockchain first.
Wrapped Bitcoin is a token on another blockchain, such as Ethereum, that is backed 1:1 by real BTC held in custody. It enables Bitcoin to be used in DeFi applications.
How Does a Bitcoin-Backed Loan Work?
The key number is the loan-to-value (LTV) ratio: how much is borrowed relative to the value of the collateral. Industry LTVs typically range from about 30% to 70%, and many lenders start at 50%. At a 50% LTV, $100,000 of Bitcoin secures a $50,000 loan.
That cushion matters because Bitcoin is volatile. When BTC's price falls, the LTV rises. Lenders set two thresholds:
- Margin call: if the LTV rises past a set level, the borrower is asked to add more collateral or repay part of the loan.
- Liquidation: if the LTV keeps rising, the lender sells some or all of the Bitcoin to cover the debt. In DeFi, smart contracts carry this out automatically.
For borrowers, these mechanics are the flip side of skipping the credit check: the collateral does the underwriting, and the pledged coins themselves are what is at stake when the market turns.
Terms vary by product. Some loans carry fixed 12-month terms with monthly interest. Others, such as Coinbase's loans, have no monthly payments and no repayment deadline; interest simply builds up on the balance.
"Rehypothecation" means a lender re-lends a customer's collateral to someone else to earn extra yield. It was a major reason customers of the lenders that failed in 2022 lost their deposits.
What Makes Bitcoin-Backed Loans Different?
The main draw is access to cash while keeping the Bitcoin. In many jurisdictions, borrowing is not a taxable event, while selling is, though borrowers should check their local rules.
The sector has also matured. Lenders now advertise that they do not rehypothecate collateral, and some offer "collaborative custody," both changes made with the 2022 failures in mind. Unchained, for example, keeps loan collateral in a 2-of-3 multisig vault: the borrower, Unchained and an independent key agent each hold one key, and no single party can move the coins alone.
Wall Street is paying attention as well. In February 2026, Ledn closed a $188 million Bitcoin-backed asset-backed securitization. S&P Global assigned its $160 million senior class a preliminary "BBB-" rating, which SVB described as the first investment-grade rating for a Bitcoin-collateralized lending portfolio. That threshold matters, since many institutional mandates limit holdings to investment-grade debt.
Galaxy put total crypto-backed loan volume at $56.16 billion in Q2 2026, down 16.8% from the previous quarter as borrowers cut back on leverage, with centralized lenders now holding more loans than DeFi protocols.
Coinbase has passed $1 billion in Bitcoin-backed loan originations, according to the company.
Who Offers Bitcoin-Backed Loans?
- Ledn: a Bitcoin-focused lender with custodied loans whose collateral is not lent out.
- Unchained: commercial loans held in multisig vaults where the borrower holds a key.
- Strike: Bitcoin-backed loans for individuals and businesses in select U.S. states.
- Coinbase: on-chain loans run through the Morpho protocol, available in most U.S. states.
- Aven: launched a Bitcoin-backed Visa credit line in April 2026 with limits up to $1 million, bringing Bitcoin-collateralized credit into everyday card spending.
- Nexo: instant credit lines against BTC and more than 100 other assets, aimed mainly at non-U.S. users.
- Aave: a DeFi lending protocol where users can borrow against wrapped BTC.
What Does a Bitcoin-Backed Loan Cost?
Rates depend on loan size, LTV and provider, and they change often. As of October 2026, published rates start at about 5.8% at Coinbase. SALT advertises 7.49% to 10.5% APR, while Ledn's rates run from 11.49% APR on loans below $250,000 down to 9.25% on loans of $2 million or more. Strike charges between 10.5% and 13% APR on loans with monthly interest payments, and a percentage more if interest is paid at maturity. Unchained quotes a 12% interest rate, or 14.18% APR. DeFi rates float with supply and demand.
Lower LTVs and bigger loans usually command better rates. Borrowers should also watch for origination fees, prepayment penalties and liquidation fees, which can push the effective cost well above the headline rate, one reason comparing APRs rather than sticker rates is the more reliable way to weigh offers.
How to Get a Bitcoin-Backed Loan
- Pick a provider. Compare the custody model, rehypothecation policy, rates and geographic availability.
- Complete KYC. Centralized lenders require identity verification.
- Choose the LTV and term. A conservative LTV leaves more room before a margin call.
- Deposit BTC into the lender's custody, a multisig vault or a smart contract.
- Receive funds in fiat or stablecoins, then monitor the LTV and repay to unlock the Bitcoin.
The Future of Bitcoin-Backed Loans
Bitcoin lending is starting to look like ordinary finance. Regulation is clearer after the GENIUS Act passed in the U.S., and the administration is friendly to crypto, although the broader CLARITY Act stalled in the Senate in September 2026, leaving the sector's fuller regulatory framework still unwritten. SVB notes that several major financial institutions launched Bitcoin-backed lending for select clients in the first half of 2026, extending a product that began with crypto-native firms into traditional banking channels.
More bank participation, more rated securitizations like Ledn's, and more consumer products such as credit cards and longer-term loans are expected. The core risk will not change, however: if Bitcoin's price drops sharply, borrowers who are overextended get liquidated.
DeFi borrowers face added risks, too. In April 2026, after attackers drained $291 million from infrastructure linked to the Kelp DAO project, users of the lending protocol Aave struggled to withdraw funds as $6.2 billion flowed out, a reminder that DeFi risk extends beyond a borrower's own collateral position.
The guidance for prospective borrowers is straightforward: borrow conservatively, and know exactly who is holding your coins.
