Track aggregate exposure against usable equity, value collateral after the exchange’s discounts, understand which positions share a margin pool, and preserve headroom above the venue’s maintenance requirements. There is no universal safe leverage or liquidation threshold: rules depend on the exchange, contract, margin mode, account and jurisdiction.
Why multiple positions can create one shared risk
With cross margin, positions that use the same shared wallet or account can draw on the same collateral. A loss in one position can therefore reduce the funds available to support other positions. Kraken’s Portfolio Management documentation describes shared portfolio risk and notes that effective leverage changes with prices and unrealized profit or loss.

Isolated margin assigns collateral to a particular position under the exchange’s rules. It can limit how much of the broader account is exposed to that position, but it does not reduce the position’s market risk. The exact boundary between shared and isolated funds depends on the venue and on whether the setting applies per position or across an account.
Altcoin positions may also react to the same market shock. Grouping exposures that could move together is a useful risk-management practice, not an assumption that every altcoin behaves identically. Portfolio-margin systems may group positions by underlying risk unit, but an exchange’s model—not a trader’s informal hedge label—determines whether an offset is recognized.

How to measure exposure against usable equity
For a simple portfolio-level check, divide the combined notional value of open positions by current account equity available to support them. Treat this as a planning ratio, not a replacement for the exchange’s own margin metric; venues may define equity, eligible collateral and margin requirements differently.
For example, if open positions have a combined notional value of $60,000 and usable equity is $10,000, the planning ratio is 6x. If losses reduce equity to $8,000 while notional exposure remains $60,000, it rises to 7.5x. The example is illustrative, not an exchange threshold or a recommended leverage level. It shows why a position’s displayed leverage can understate portfolio risk when several positions share collateral.
Use current account values, including unrealized P&L, and revisit the calculation as prices move. Kraken describes effective leverage as positions relative to portfolio value and notes that it changes when prices and unrealized gains or losses change. Your platform’s displayed figure may use its own definitions, so check the account’s margin interface and product documentation.

How collateral haircuts change the buffer
A token’s displayed market value is not necessarily the amount the exchange will count toward margin. Exchanges can limit eligible collateral and discount its value using a haircut, collateral ratio or discount rate. A conceptual estimate is:
Margin value of an asset ≈ its market value × the exchange’s current collateral factor.
This is only a way to understand the discount; it is not a complete venue-specific equity formula. The actual calculation may also account for liabilities, unrealized P&L, conversion rates and other rules.

- OKX says its portfolio-margin system converts crypto equity into a USD-equivalent value using discount rates that reflect liquidity differences.
- Kraken’s Multi-Collateral Derivatives guidance for EEA clients says non-USD assets are subject to haircuts.
- Binance says its margin calculations use asset collateral ratios and price indices.
Before relying on an asset as a buffer, check whether it is eligible for your account and contract, what factor applies now, and whether the exchange can change that factor. A collateral token can lose market value at the same time that open positions lose value, tightening headroom from both sides.

How to choose between cross and isolated margin
Neither mode is universally safer. Cross margin can make more funds in a shared pool available to support positions, while also allowing losses to consume that pool. Isolated margin can contain the collateral assigned to a position, while leaving the market risk of that position intact.
| Question | Cross margin | Isolated margin |
|---|---|---|
| Which funds can support a position? | Funds in the shared wallet or account, as defined by the venue. Kraken documents shared portfolio risk for its Portfolio Management product. | Collateral assigned to that position under the venue’s rules. Kraken documents isolated margin as a way to confine collateral risk to the position. |
| Can a loss affect other positions? | Yes, when those positions draw on the same pool. | The assigned collateral is the intended boundary; verify the exchange’s precise liquidation and settlement rules. |
| Does the mode remove market risk? | No. | No. |
| Where is the exact setting scope documented? | In the exchange’s account and product rules; it can vary. | In the exchange’s account and product rules; it can vary. |
When comparing venues or modes, establish which positions and wallets share collateral; what assets qualify and how their discounts work; whether margin is position-tiered or based on portfolio stress; what metric triggers liquidation and in what sequence; and how funding, conversion fees and settlement currency affect equity. Kraken describes a Holding wallet as segregated from active trading wallets, which can be relevant when deciding what funds to keep outside trading activity.

How position tiers and portfolio stress tests affect requirements
A position can require a different maintenance margin as its size changes. Kraken says its maintenance-margin schedule increases required margin as position size increases, so adding to a position may change its requirement rather than simply scaling it in a straight line. Check each contract’s current tier schedule before increasing exposure.
Portfolio margin can work differently from a simple position-by-position calculation. OKX’s “Portfolio margin mode: cross-margin trading (Risk Unit Merge)” documentation describes grouping by underlying risk unit and stress-testing scenarios that include extreme market moves, basis risk and stablecoin depeg risk. It also describes a minimum charge intended to cover liquidation fees, transaction costs and slippage. The documentation was published December 3, 2024, and updated August 5, 2026; these details apply to that OKX product, not all portfolio-margin systems.

How to run a practical account check
- List positions: Record each open contract, direction, notional value, collateral currency and margin mode. Mark which positions use a shared wallet or account.
- Group related shocks: Identify altcoin positions that could be exposed to the same broad market move. This is a planning aid, not a prediction that the assets will move identically.
- Check account-level exposure: Review combined position value against current usable equity, including unrealized P&L. Use the exchange interface for its official margin measures; use a portfolio-level ratio only as a separate planning check.
- Revalue collateral: Confirm each asset’s eligibility and current haircut or collateral ratio, then use the platform’s margin value rather than its headline spot value.
- Review maintenance tiers and stress rules: Check the current requirements for every contract at the intended position sizes, and understand whether the venue uses position tiers, portfolio stress tests or both.
- Choose the risk boundary: Decide whether a shared pool’s flexibility is appropriate or whether assigning collateral per position better matches your risk plan. Confirm the setting’s scope in the product documentation.
- Set a review trigger: Recheck headroom after sharp price moves, losses, funding, collateral-factor changes, conversions or withdrawals. Leave enough room for the venue’s requirements and potential costs rather than relying on a single displayed leverage number.
What liquidation thresholds can—and cannot—tell you
Liquidation triggers are product-specific. OKX describes alerts and a 100% maintenance margin ratio trigger for the portfolio-margin mode documented on its page; that threshold is not a general futures rule. It should not be combined with another exchange’s tiers or margin definitions.
Binance’s “Binance Margin Level and Risk Control” page, updated September 28, 2026, gives thresholds for Binance Cross Margin Classic: for the 3x product, a margin-call band above 1.1 and at or below 1.3, with liquidation at or below 1.1; for the 5x product, a margin-call band above 1.1 and at or below 1.16, with liquidation at or below 1.1. These are Binance cross-margin thresholds, not altcoin-futures thresholds or general recommendations. Do not use them to estimate a futures liquidation price.
For your own positions, confirm the current maintenance tiers, collateral schedule, liquidation metric and liquidation sequence in the exchange’s documentation and interface. Those details may vary by contract, account mode, jurisdiction or account tier, and can change.
How withdrawals and conversions affect headroom
Removing funds from a trading wallet while positions remain open reduces available equity and can raise effective leverage. Kraken explicitly warns that withdrawing funds from a trading wallet with open positions can increase effective leverage and may lead to liquidation.
Funding payments and other realized costs can also reduce equity. Converting collateral may change its margin value, and settlement or conversion rules can add costs; Kraken’s Multi-Collateral guidance describes USD conversion and conversion fees in certain settlement situations. Recheck the account after these operations instead of assuming the prior buffer is unchanged.
