Kraken’s newly regulated U.S. margin push is bringing a familiar crypto risk back into focus: traders using crypto as collateral may be relying on a liquidation price that does not stay fixed after the trade is opened.
The issue appears directly in Kraken’s own margin documentation. The exchange explains how traders can estimate a margin-call price for a leveraged long position, but warns that the calculation assumes collateral balances are fully composed of USD.
The assumption changes how much protection a trader actually has when markets move against a leveraged position. With USD collateral, the margin buffer remains fixed in dollar terms as the trade moves. With BTC or ETH collateral, the collateral itself can lose USD value during the same market move that pushes the position toward liquidation.
Kraken’s BTC Example Shows the Difference
Kraken gives an example of a trader opening a 5x long BTC spot margin position at $20,000. In the example, the trader buys 1 BTC, uses $4,000 in margin, and the account metrics assume collateral balances are 100% composed of USD.
Under that setup, Kraken estimates that BTC would need to fall to around $13,200 for the trader’s margin level to drop to 80%, which is the exchange’s approximate margin-call level.
But Kraken adds an important caveat. If digital assets such as BTC or ETH are used as collateral, the USD value of that collateral would fall as the price of that asset falls. Kraken says this can cause the margin-call price to be higher than the standard calculation suggests.
In other words, the $13,200 level applies to the clean USD-collateral example. It does not behave the same way when crypto collateral is also falling in dollar terms.
Why the Margin Floor Moves
For a BTC long backed by USD, only the position is moving against the trader when BTC falls. The collateral balance remains stable in dollar terms.
For a BTC long backed by BTC, two things happen at once. The long position loses value, and the BTC used as collateral also becomes worth fewer dollars. That weakens the account’s margin position faster than a static entry calculation may imply.
Kraken’s margin call level is approximately 80%, though the exact threshold can vary with price volatility. The exchange says spot margin liquidation begins when margin health reaches 40%, and once the liquidation process starts, it is automated and cannot be stopped.
That makes collateral selection central to liquidation risk. The leverage ratio may be the same, and the entry price may be the same, but the effective margin-call level can change depending on what asset is used to back the trade.
U.S. Margin Rollout Puts Collateral Risk in Focus
The timing is important because Kraken’s parent company, Payward, completed its $550 million acquisition of Bitnomial in May, giving the group a full CFTC-regulated derivatives stack in the United States.
Kraken then launched CFTC-regulated spot margin trading for eligible U.S. clients on Kraken Pro.
In a separate expansion of its U.S. derivatives push, Kraken also announced plans to launch CFTC-regulated perpetual futures for eligible U.S. traders through Bitnomial, with the contracts expected to sit alongside spot trading, margin trading, and CME-listed crypto futures on Kraken Pro
That opens regulated onshore margin access to a wider group of U.S. retail traders. It also means more traders may now be dealing with a product where liquidation risk depends not only on price direction and leverage, but also on the market value of collateral.
For new margin users, the distinction can be easy to miss. A trader may write down a liquidation or margin-call estimate at entry, assuming the number is fixed. But if the collateral is BTC, ETH, or another volatile digital asset, the account’s dollar-value support can move during the trade.
Experts say traders may be using the wrong assumption, Anton Palovaara, founder at Leverage.Trading, said,“Kraken flags it in their own documentation: when you use crypto as collateral, the margin call price at entry is already wrong. The 80% threshold is fixed. The value of what backs your position is not. By the time BTC has fallen enough to hurt the trade, your collateral is worth less too — and the floor has already moved up.”
Leverage.Trading’s analysis of crypto collateral and liquidation risk explains that traders can face different effective liquidation levels across platforms even when they use the same leverage and entry price. The difference comes from how collateral is valued and how quickly the account’s margin buffer changes during a move.
Weekend Gaps Can Make It Worse
The risk can become sharper during thin liquidity periods, especially on weekends. A sudden move lower can reduce the value of the open position and the crypto collateral at the same time.
That can compress the margin buffer before a trader has time to respond. Kraken also says margin call notifications are not guaranteed, making active monitoring important for leveraged accounts.
For traders using BTC as collateral on a BTC long, the risk is not just that Bitcoin falls. The risk is that the same fall also weakens the collateral supporting the position.
The result is simple but important: the liquidation price calculated at entry may not be the liquidation risk that matters once the market starts moving.
