How long do you have to meet a bitcoin loan margin call?
Strike's page says 72 hours, Arch says typically 24, Ledn and SALT print LTV levels rather than hours. Each lender's cure window, read 4 October 2026.
By Staff, Lend Ledger
How long you have to meet a margin call on a bitcoin loan depends on the lender, and some published pages give no time at all. Strike’s borrow page says 72 hours. Arch says it typically provides 24 hours. Ledn’s and SALT’s pages give LTV levels, not hours. No lender page read here promises the clock beats the price.
That last sentence is the one that matters. A margin call has two limits, a clock and a price, and whichever is hit first decides what happens to the collateral. This is an evergreen explainer: the question of how long you have to meet a margin call on a bitcoin loan does not change with the market, though each lender’s figure can. So every figure below is pinned to the page it came from, and this desk read each of those pages on 4 October 2026. The binding number is always the one in your own loan agreement, which no page read here replaces.
How long do you have to meet a margin call on a bitcoin loan?
The table puts each lender’s stated time beside the level at which collateral can be sold anyway. The securities row is there as a baseline, not because a crypto loan works under the same rules. Where a page states nothing, the row says so; that is a statement about the page read, not about the lender’s contracts.
| Lender and page read | Time to respond, as the page puts it | Level where collateral can be sold or converted anyway | Can the window be skipped? |
|---|---|---|---|
| Strike, borrow page | “Advance notice before a margin call. 72 hours to respond.” | No liquidation LTV stated in the page text | Not stated; only the collateral needed to restore the LTV is liquidated |
| Strike, Volatility Proof Loans (same page) | No margin calls | No price-driven liquidations while payments are current | No price window to skip; the clock is the payment schedule |
| Arch, margin-call explainer | “Typically” a 24-hour window; an extension can be requested | 70% / 80% / 90% shown only as a generic example | Yes: an extension is never guaranteed and typically won’t apply at the liquidation threshold |
| Ledn, loan-management guide (updated 9 September 2026) | No time stated; notifications at 70% and 75% LTV | Automatic liquidation at or above 80% LTV | Yes: a notification is not a guaranteed opportunity to act |
| SALT, margin-call page (published 3 July 2026) | No figure in hours or days; a call “usually comes with time to respond” | 90.91% LTV, where Stabilization converts collateral to a stablecoin such as USDC | SALT Shield, where eligible, forbears margin calls and liquidation for the rest of the term |
| Merrill Edge, US securities margin (baseline) | Maintenance and Reg T calls resolved within 2 business days | 30% maintenance requirement on long shares trading over $10 | Yes: it can sell immediately without notice, even after giving a date |
Read across the columns rather than down. Strike prints the longest clock but no sale level in words; Ledn prints a sale level but no clock; SALT prints a level and a protective conversion but no clock; Arch prints a short clock and warns it can be overtaken. Not one of the lender pages read promises that the clock beats the price.
Why Strike’s window appears as both 72 hours and 24 hours
Strike’s borrow page, read 4 October 2026, lists under “Protection”: no surprise margin calls, advance notice before a margin call, 72 hours to respond, and only the collateral needed to restore your LTV liquidated. The page’s calculator is labelled illustrative only and “Available in select US states”, and its footer says credit products may be available to eligible users in certain jurisdictions. So the 72 hours is what Strike’s own marketing page states, scoped to the loans that page describes.
A second figure is in circulation. Ledn’s comparison of the two lenders, last updated 7 September 2026 and carrying Ledn’s own disclosure that it has a commercial interest in its products, attributes to “Strike’s current FAQ” a margin call at 70% LTV after which the borrower “generally has 24 hours” to bring the ratio to 60% or below, and a partial liquidation at 85%. This desk did not read Strike’s FAQ, so it cannot say which document is current or whether the two describe different products or jurisdictions. What can be said is that a competitor’s page and Strike’s own page disagree by a factor of three, and that a borrower should take the figure from their own Strike agreement, not from either web page.
The same Strike page offers a separate product, Volatility Proof Loans, which it describes as having no margin calls and no price-driven liquidations as long as payments are current. On that product the question in the title has no answer in hours, because there is no price-triggered call; the deadline that matters is the payment date. What that promise does and does not cover is set out in our Strike assessment.
What Arch means by a “typically” 24-hour window
Arch’s margin-call explainer is the only page read here that explains the cure window as a concept. It says a stockbroker might give two to five days, an exchange running leveraged perpetuals might give minutes, and a crypto lending platform like Arch typically provides a 24-hour window, with borrowers able in some cases to request an extension.
Three qualifiers sit inside that sentence and the ones around it. “Typically” means the 24 hours is not presented as a fixed term. The extension is, in Arch’s words elsewhere on the page, never guaranteed, and it typically won’t apply if the position hits the liquidation threshold. And Arch says that in highly volatile markets the price can blow straight through the margin call level and hit the liquidation threshold before the borrower has time to react.
Two things on the page are easy to misread as Arch’s terms. The 70% / 80% / 90% ladder is introduced as what “a lending platform might” do, an example rather than a schedule. And the FAQ’s answer that lending platforms “typically” give 24 to 72 hours is a general statement with no lender named behind it. Neither belongs in a comparison as a published Arch figure, and the table above does not use them as one. What Arch does state as its own practice is partial liquidation: if the borrower neither adds collateral nor repays, it sells just enough collateral to bring the LTV back to its pre-defined threshold.
Ledn and SALT print levels, not hours
Two of the four lenders give a borrower no clock on the pages read. That is not the same as having no cure period; their loan agreements were not read, and either may set one. It does mean a borrower comparing lenders from their public pages cannot compare a number that is not printed.
Ledn: two notices, then a sale at 80%
Ledn’s loan-management guide, which shows “Updated 9 September 2026” (and also a “Last updated: June 8, 2026” line), says Ledn’s published guidance identifies notifications at 70% and 75% LTV and automatic liquidation at or above 80%. It adds that notification delivery is not a guaranteed opportunity to act before a rapid market move. The guide frames the job as preparing while the loan is healthy, not assuming an alert will leave enough time.
Because Ledn gives levels rather than hours, the useful conversion is from levels to a price move. On a constant balance, the collateral has to lose a further 12.5% of its value to take a loan from the 70% notice to 80%, and 6.25% to go from the 75% notice to 80%. That is this desk’s arithmetic on Ledn’s published levels (1 minus 70/80, and 1 minus 75/80); interest accruing on the balance shortens both distances. On those figures the second notice arrives with little room behind it.
Ledn’s optional Auto Top-Up acts at the first level: the guide says an enabled loan reaching 70% LTV uses BTC from the Transaction Account to target 68%, and that if the balance is insufficient, the available amount may be used without restoring the full target. It also notes that bank and blockchain transfers have processing times, which is the practical reason a time window matters less than having the money already in place.
SALT: a conversion at 90.91%, and a fee-based exemption
SALT’s margin-call page, published 3 July 2026, says a margin call usually comes with time to respond. A search of the page for hours and days found no figure, so the page does not say how much time. What it does state is a high threshold: SALT sets its threshold at 90.91% LTV, at which its Stabilization feature converts the crypto collateral to a US dollar stablecoin such as USDC. Once the borrower brings the LTV back to 83.33% or below through a payment or a deposit, they can convert back into crypto. Loans are offered at LTV tiers of 30%, 50% or up to 70%.
The page also describes SALT Shield, an upgrade for a one-time fee under which SALT will forbear the triggering of margin calls and liquidation events for the remainder of the loan term. Eligibility, as the page states it, includes loans above $50,000, a current LTV under 70%, and enrolment at least three months before maturity, and availability depends on jurisdiction. On a shielded loan, as with Strike’s Volatility Proof product, the margin call clock is replaced rather than lengthened. Where SALT’s warning and margin-call levels sit on its full ladder is tabulated in our post on liquidation LTVs.
Can a lender liquidate before the margin call deadline?
On the pages read, the answer is yes wherever the price keeps falling, and no page read here promises otherwise. Arch says the price can pass straight through the call level to the liquidation threshold, and that an extension typically does not apply once it does. Ledn says a notification is not a guaranteed opportunity to act. Strike’s page, for its standard loan, states a 72-hour window but no liquidation level in words, so it does not say what happens if the LTV keeps climbing inside those 72 hours.
The securities baseline is blunter. Merrill Edge’s margin page says maintenance calls and Regulation T calls must be resolved within 2 business days. It then says that even if Merrill has contacted the customer and given a specific date, it can still take steps to protect its interests, including immediately selling the securities without notice, and that the customer is not entitled to an extension. That is US securities margin, not a crypto loan, and nothing here suggests a crypto lender is bound by Regulation T. It is included because it is the plainest statement read of a principle the crypto pages imply: the deadline is a courtesy to the borrower, and the lender’s right to sell does not wait for it.
There is also a second clock that has nothing to do with price. Ledn’s guide says that loans in ineligible jurisdictions do not automatically renew and, if not repaid, are liquidated at maturity with no grace period. Under its renewal guidance, updated 2 September 2026, an eligible loan above 65% LTV at renewal has enough BTC sold to bring it to 64% before the rest renews. A borrower can do everything right on margin calls and still face a sale on the maturity date.
How do you cure a margin call on a bitcoin loan?
The lender pages read here that describe a cure give the same two actions: add collateral or repay part of the loan, until the LTV is back below the lender’s level. SALT’s page names a third, on some platforms: relying on a built-in protective feature. Ledn adds Auto Top-Up. What differs is how far back each lender wants the LTV. Arch sells to its pre-defined threshold; Ledn’s Auto Top-Up targets 68%; Ledn’s comparison says Strike’s FAQ targets 60% or below; SALT’s re-entry level is 83.33%.
The window is measured from the notice, not from when a borrower sees it. A 24-hour window that opens overnight, or a bank transfer that settles the next business day, can consume most of the time before any collateral moves. Strike’s 72 hours is the longest clock printed on any crypto lender page read here, but even that assumes the LTV stops rising while the borrower acts.

Questions borrowers ask about margin call deadlines
How long do I have to respond to a crypto margin call?
As long as your lender’s agreement says, and the published figures differ. Strike’s borrow page says 72 hours; Arch’s explainer says it typically provides 24 hours; Ledn’s and SALT’s pages read here give LTV levels rather than a time. Arch’s own FAQ quotes a general 24 to 72 hours for lending platforms, but it names no lender behind that range.
How can I cure my margin call?
On the lender pages read here that describe a cure, it is the same pair of actions: add collateral, or repay part of the loan, until the LTV is back under the lender’s level. Ledn adds an optional Auto Top-Up that moves BTC from a funded Transaction Account at 70% LTV. Bank and blockchain transfers take time, so the money needs to be ready before the call arrives.
What happens if you don’t meet a margin call?
The lender sells collateral. How much differs: Strike’s borrow page says only the collateral needed to restore the LTV is liquidated, and Arch says it partially liquidates to bring the LTV back to its threshold. Ledn’s guide says liquidation is automatic at or above 80% LTV. Arch adds that a liquidation is generally treated as a sale, and so as a taxable event.
Can a lender liquidate before the margin call deadline?
On the pages read, yes, if the price keeps falling. Arch warns that price can blow straight through the margin call level to the liquidation threshold, and says an extension typically won’t apply once that threshold is hit. Ledn says a notification is not a guaranteed opportunity to act. A cure window is time to fix a call, not a promise that nothing is sold meanwhile.
Nothing above describes any of these lenders as regulated, licensed or authorised anywhere; no register was read for this piece, and no right to an extension or a cure period is claimed beyond the words each page uses. Every window and threshold quoted is the lender’s own published figure as read on 4 October 2026, and the loan agreement overrides it. Borrowing against bitcoin carries a high risk of loss, up to the whole of the collateral through liquidation or counterparty failure, and nothing here is financial advice.
