Bitcoin-backed lending is borrowing cash, usually US dollars or another major currency, with Bitcoin pledged as collateral. For a company, it offers a way to raise short-term liquidity without selling a long-term holding. The trade-off is that the loan becomes exposed to Bitcoin's price, through margin calls and possible liquidation, and to the lender's handling of the collateral.
How Bitcoin-backed lending works
The structure is similar to any secured loan, with a few features specific to a volatile, continuously traded asset.
- Collateral is pledged. The company transfers Bitcoin to the lender, or to a custodian acting under a pledge or control agreement.
- Cash is advanced at a loan-to-value (LTV) ratio: the loan amount as a percentage of the collateral's market value.
- The LTV is monitored continuously. Because Bitcoin trades around the clock, so does the lender's risk system.
- Margin calls follow price falls. If the LTV rises above a set level, the borrower must add collateral or repay part of the loan within a short window.
- Liquidation is the backstop. If the borrower does not meet the call, the lender may sell enough Bitcoin to restore the LTV or close the loan.
- Repayment releases the collateral. When the loan and interest are repaid, the Bitcoin is returned.
Why a company might borrow against Bitcoin
Corporate uses tend to be practical rather than speculative.
- Bridging liquidity. Covering a temporary cash need, such as a seasonal working capital peak, without disturbing a long-term holding.
- Avoiding a forced sale. Keeping a reserve intact through a period when selling would breach the policy's holding intent.
- Tax timing. In some jurisdictions, borrowing does not trigger the tax a sale would. This depends entirely on local rules; take tax advice.
- Diversifying funding. Adding a secured facility alongside bank lines.
Some companies also consider borrowing against Bitcoin in order to buy more Bitcoin. That magnifies exposure to the same asset and is a different decision altogether. We discuss it in funding a corporate Bitcoin purchase.
Loan-to-value in practice
The LTV determines how much room the company has before a margin call. The table below is illustrative only; actual terms vary by lender and market conditions.
| Starting LTV | Margin call level | Price fall before margin call | Liquidation level | Price fall before liquidation |
|---|---|---|---|---|
| 25% | 50% | about 50% | 65% | about 62% |
| 40% | 60% | about 33% | 75% | about 47% |
| 50% | 65% | about 23% | 80% | about 38% |
Bitcoin has experienced falls of these sizes, sometimes within weeks. A starting LTV that looks comfortable in a calm market can become a margin call quickly.
CFO tip: set the company's own maximum LTV well below the lender's margin call level, and pre-fund a margin reserve in cash or unencumbered Bitcoin. If the reserve would not cover a fall of the size seen in past drawdowns, the loan is too large.
The risks to control
Price and margin risk
The obvious risk. A fall triggers calls that must be met quickly, often outside business hours. If the company cannot respond in time, it may lose Bitcoin at a low price through liquidation.
Counterparty and rehypothecation risk
This is the risk that caused the most damage in 2022, when several lenders in the digital asset market failed. Borrowers who had pledged Bitcoin found that the lender had reused, or rehypothecated, the collateral, and that it was not available to return.
Key questions:
- Does the agreement allow the lender to reuse, lend or pledge the collateral?
- Is the collateral held by an independent custodian, in a segregated account?
- What happens to the collateral if the lender becomes insolvent?
Our guides to settlement and counterparty risk and bankruptcy remoteness in custody cover these issues in depth.
Operational risk
Margin calls need fast action: approvals, transfers and confirmations. If the company's signing policy requires several senior approvers who are hard to reach at weekends, the process can fail at the critical moment. Plan the operational workflow before drawing the loan.
Legal and accounting risk
The loan documentation, the pledge, the governing law and the custodian's role all need legal review. On the accounting side, questions include whether pledged Bitcoin is still recognised on the balance sheet and how it is disclosed as restricted. Under ASU 2023-08, companies must disclose restrictions on their holdings. Companies should take their own accounting, tax and legal advice.
Structures that reduce risk
Not all Bitcoin-backed lending carries the same risk. Safer structures tend to share these features:
- Tri-party custody. The Bitcoin sits with an independent qualified custodian under a control agreement, not with the lender.
- No rehypothecation. The agreement forbids reuse of the collateral.
- Conservative LTV. Lower starting ratios and clear, generous margin call windows.
- Transparent liquidation terms. How, where and at what price collateral would be sold.
- Clear reporting. Daily LTV statements and real-time alerts.
Governance requirements
A Bitcoin-backed facility should be approved by the board as a borrowing decision, not only as a treasury operation. The Bitcoin treasury policy should state whether pledging Bitcoin is permitted, the maximum LTV, approved lenders and custodians, and who may respond to margin calls. Lender due diligence should be as thorough as custodian due diligence; see choosing a Bitcoin custodian.
How The Bitcoin World helps
We help companies decide whether Bitcoin-backed lending suits their needs, set LTV and margin policies, and design collateral and custody arrangements that limit counterparty exposure. Lending, execution and custody are carried out by licensed third-party institutions; we do not hold client assets or lend. See our custody architecture and corporate treasury services.
