Deep Tide Guide: The game of listed companies borrowing money with Bitcoin as collateral is becoming deadly—once a warning line is triggered, some contracts only give 12 hours to top up collateral or repay the loan, otherwise the lender has the right to sell the coins directly. In February 2026, two companies have already received margin calls. This is not a theoretical risk, but a liquidity trap that is happening right now. For investors, the "holding XX BTC" numbers in a company's financial reports could turn into the trigger for a forced sell-off at any moment.
When a listed company's Bitcoin treasury reserves are pledged to a lender, their nature changes. They become collateral, measured by loan-to-value ratios, potentially forcing the company to add more Bitcoin, repay the debt within hours, or face the lender's right to sell.
This risk is no longer theoretical. Fold received a formal collateral maintenance notice in February and added 50 BTC. Empery Digital's ongoing loan crossed the margin call threshold, and the company added 576 BTC. Nakamoto separately added 688 BTC to meet maintenance requirements.
Fold disclosed the formal lender notice. Empery and Nakamoto reported adding collateral after hitting loan thresholds. However, there is no indication that any lender issued a formal call. Furthermore, none of the companies reviewed by CryptoSlate reported lenders selling their pledged Bitcoin.
Throughout July 14th, Bitcoin traded between $61,988 and $64,207, down 19-23% from 60 days ago. No documents show that a 12- or 24-hour response clock has been triggered due to the current price drop. However, breaching thresholds again could turn market volatility into immediate liquidity decisions.
Collateral Pressure Has Already Forced Companies to Act
Fold provides the clearest example of a formal call. The company received a collateral maintenance notice on February 5th after Bitcoin fell below the threshold in its loan agreement. It added another 50 BTC within the stipulated notice period.
Fold reported a $20 million outstanding balance and 430 BTC pledged as of March 31st. In June, it sold approximately $45 million worth of Bitcoin at an average price of around $71,000 and repaid the entire $20 million balance.
The company initiated this sale and repayment.
Empery Digital's filings used different wording. Its ongoing Two Prime financing fell below the margin call threshold on February 4th, leading the company to add 576 BTC to restore coverage.
Six days later, Empery amended the loan. New terms lowered the initial collateral ratio from 250% to 174%, the margin call line from 175% to 153%, and the liquidation line from 150% to 143%.
As of March 31st, Empery had a $45 million outstanding balance under this agreement with 1,096 BTC pledged. Its July update again reported $45 million in debt (after actively repaying $10 million) but did not provide a new pledged BTC figure.
The company also stated that since May 7th, it had sold 1,400 BTC at an average price of approximately $62,200, leaving it with 1,514 BTC and $73.9 million in cash. These were company-initiated treasury and repayment decisions, not reported lender liquidations.
Nakamoto disclosed another form of collateral pressure. On February 5th, it added 688 BTC to meet maintenance requirements for a 210 million USDT loan, bringing the pledged amount to approximately 4,405 BTC.
Nakamoto later refinanced this position. It sold about 600 BTC and exited derivative positions, generating approximately $48 million in net proceeds. It used $45 million to reduce the loan to 165 million USDT, with the new financing initially collateralized by 3,805.112 BTC.
Its filings describe maintenance and liquidation thresholds but do not disclose specific numbers. This makes it impossible to reliably calculate how much Bitcoin would need to fall to trigger another action.
These filings track what can happen before liquidation. The lender flags a default, the borrower adds collateral, and then may sell assets, refinance, or repay debt.
Some Contracts Give Borrowers Only Hours to Respond
These agreements show how quickly companies might need to act when collateral buffers shrink. Because each contract measures risk and issues notices differently, headline ratios cannot provide a like-for-like ranking.
USBC provides the clearest company calculation of its buffer. It stated that the value of its pledged Bitcoin could fall another 18.2% from July 2nd levels before hitting the 130% margin call ratio, assuming it neither repays principal nor adds collateral.
USBC also stated that as of July 2nd, no collateral calls, mandatory repayments, or liquidation events had occurred. In fact, Bitcoin has risen about 5% since then.
Its quarterly filing said the February amendment shortened the period to provide collateral below the liquidation level to 12 hours.
However, the submitted loan amendment also stated that breaching the 143% liquidation level automatically constituted an event of default, allowing the lender to sell the collateral without notice. The disclosure does not support treating the 12 hours as an unconditional grace period.
We can also look at Hut 8, which added another active financing with a short timeline. The company entered into a $200 million "Charlie" loan with FalconX on May 1st at 7% interest, using the proceeds to repay an earlier Coinbase financing.
According to Hut 8's quarterly filing, the refinancing freed approximately 3,300 BTC from the previous collateral arrangement. The company did not disclose the exact amount pledged under the new FalconX loan.
Under the FalconX agreement, falling below the 130% margin call level allows the lender to issue a notice, requiring funds or collateral within 24 hours.
At the 105% default level, a borrower providing the required officer certificates promptly may receive an extension, but for no more than 12 hours or the remainder of the original 24-hour period, whichever is shorter. If these conditions aren't met, lender rights may accrue without extension.
The Clock Matters Before Liquidation Begins
These filings cannot tell us which borrower is closest to a margin call. They can show how quickly pressure builds once coverage is broken.
The lack of standardized reporting metrics truly muddies the waters.
USBC does not directly state its pledged Bitcoin amount. Empery's last disclosed collateral figure is from March 31st, even though its debt was updated in July. Hut 8 did not disclose the exact amount securing its FalconX loan, and Nakamoto omitted the specific numbers for maintenance and liquidation thresholds.
Using these mismatched disclosures to calculate Bitcoin trigger prices creates false precision. Repayments, collateral transfers, interest, and contract-specific valuation rules can all alter a company's coverage without a corresponding move in the Bitcoin spot price.
This doesn't mean the contractual risk is theoretical. Companies receiving notices will have to raise cash, transfer more Bitcoin, or repay debt within the applicable window. In some agreements, that decision can be measured in 12 or 24 hours.
The most important distinction lies between a forced response and lender liquidation. Fold, Empery, and Nakamoto have already disclosed notices, threshold breaches, or maintenance additions. They later sold assets, refinanced financing, or reduced debt, but reviewed filings describe these as borrower actions.
Lenders don't have to sell pledged Bitcoin to tighten company positions. The loans themselves can lock up more reserves, force companies to scramble for cash, and turn passive holdings into immediate liabilities.
The next meaningful signal will be filings reporting new notices, collateral transfers, repayments, threshold changes, or lender actions.
Until then, corporate Bitcoin reserves can sit untouched for years when unencumbered. But once they back a loan, contractual ratios and response clocks determine how long a company has to act. And Bitcoin financing is becoming a trend, especially for miners trying to weather the winter.
Bitcoin is up 3.99% in the past 24 hours and is currently ranked #1 by market cap.
