BTC and ETH Futures Now Offer Up to 150× Leverage
Phemex has increased the maximum leverage available on selected BTC and ETH perpetual futures markets from 100× to 150×. The update covers the BTCUSDT, BTCUSDC, ETHUSDT, and ETHUSDC contracts shown in Phemex’s product communication.
The change gives experienced traders more flexibility when managing capital and exposure. At the same time, 150× leverage significantly reduces the margin buffer available before liquidation. It should therefore be viewed as a capital-efficiency feature, not as a reason to increase risk automatically.
Phemex’s published risk-limit updates for BTCUSDC and ETHUSDC show maximum leverage of 150× in the lowest position tiers, with higher margin requirements applied as position size increases. See the BTCUSDC risk-limit update and the ETHUSDC update.
What Does 150× Leverage Mean?
Leverage allows a trader to control a larger notional position with a smaller amount of initial margin.
For example, at 150× leverage, a $15,000 futures position may require approximately $100 in initial margin before trading fees and other contract-specific requirements. The calculation is simple: notional position value divided by leverage.
However, this does not mean that a trader can safely lose the entire $15,000 position while risking only $100. The position’s profit and loss is calculated on the full notional value. A 1% movement in the underlying asset would represent approximately $150 of profit or loss on a $15,000 position.
The margin is simply the collateral used to open and maintain the position. It is not a maximum-loss guarantee.
Why Has Phemex Increased the Leverage Limit?
The update reflects the changing structure of the crypto derivatives market. Compared with the early market conditions of 2019, BTC and ETH now benefit from broader participation, more mature derivatives infrastructure, and greater trading activity across global markets.
Those developments can support tighter execution and deeper liquidity in major contracts. They may also allow experienced traders to use capital more efficiently when implementing hedging, arbitrage, market-neutral, or short-term strategies.
The important distinction is that lower or more orderly volatility does not mean low risk. BTC and ETH can still move sharply during macroeconomic announcements, liquidation cascades, network events, or sudden changes in market sentiment.
Higher maximum leverage gives traders more choice. It does not remove the need for stop-losses, position limits, or a sufficient account buffer.
Which BTC and ETH Contracts Are Covered?
The product communication highlights four contracts:
| Contract | Margin currency | Maximum leverage shown |
|---|---|---|
| BTCUSDT | USDT | Up to 150× |
| BTCUSDC | USDC | Up to 150× |
| ETHUSDT | USDT | Up to 150× |
| ETHUSDC | USDC | Up to 150× |
Actual leverage depends on the contract, position size, risk-limit tier, margin mode, and current platform parameters. The maximum advertised leverage normally applies only to smaller position brackets. Larger positions generally require a higher initial-margin rate and maintenance-margin rate.
Phemex’s published BTCUSDC table, for example, shows 150× leverage in the first risk tier, followed by lower maximum leverage levels as position value rises. The ETHUSDC table follows a similar tiered structure. Traders should always confirm the applicable tier in the order panel before opening a position.
Initial Margin and Maintenance Margin
Two margin concepts are especially important when using 150× leverage.
Initial margin is the collateral required to open a position. At 150× leverage, the theoretical initial-margin rate is approximately 0.67%, although fees and platform rules can affect the final amount.
Maintenance margin is the minimum collateral required to keep the position open. If account equity falls below the maintenance requirement, the position may be liquidated.
Phemex’s risk-limit tables show that maintenance-margin rates rise with larger position tiers. This means a trader cannot assume that the same leverage and margin percentage apply to every position size.
Phemex explains that maintenance margin directly affects liquidation prices and that larger positions can move into brackets with higher requirements. Review the Phemex risk-limit guide for more detail.
Why 150× Leverage Can Increase Liquidation Risk
Leverage magnifies the effect of price movements on margin. A position opened with 150× leverage has a much smaller initial collateral buffer than a position opened with 10× or 20× leverage.
A small adverse move can therefore produce a large percentage loss relative to the margin posted. The exact liquidation level depends on factors such as:
- Entry price
- Position direction
- Position size
- Initial margin
- Maintenance margin
- Trading fees
- Funding payments
- Margin mode
- Mark price
- Other open positions in the account
Liquidation is not necessarily triggered by the last traded price. Phemex states that mark price is used for liquidation and unrealized PnL calculations. Read Phemex’s futures liquidation protocol.
This is why traders should not estimate liquidation risk using leverage alone. The estimated liquidation price displayed by the trading interface is more useful because it reflects the selected contract and position parameters.
A Simple 150× Trading Example
Assume a trader opens a BTC perpetual futures position with a notional value of $15,000 at 150× leverage.
The approximate initial margin is $100. If BTC rises by 0.5%, the gross position profit is about $75. Relative to the initial margin, that represents a 75% return before fees and funding.
If BTC falls by 0.5%, the gross loss is also about $75. The trader would have used most of the initial margin buffer even though the underlying asset moved by only half of one percent.
This example shows both sides of high leverage. It can make capital usage more efficient, but it also leaves less room for normal market noise. A stop-loss placed too close to the entry price may be triggered frequently, while a stop-loss placed too far away may leave the position exposed to liquidation.
How Experienced Traders May Use the New Limit
The availability of 150× leverage does not mean every trade should use 150×. Professional traders often use high leverage in more specific ways.
Capital efficiency
A trader may use higher leverage to reserve more account capital for other positions, hedges, or liquidity needs while keeping the same notional exposure.
Short-term strategies
Scalpers and high-frequency traders may hold positions for a short period and seek to limit the amount of collateral committed to each trade.
Hedging
A trader holding spot BTC or ETH may use perpetual futures to hedge directional exposure. The objective is not necessarily to maximize profit, but to reduce portfolio sensitivity to price changes.
Market-neutral structures
Some traders use offsetting positions across related instruments. These strategies can still carry basis risk, funding risk, execution risk, and liquidation risk.
In each case, the notional position should be determined by the trading plan first. Leverage should be selected afterward.
A Better Way to Choose Position Size
A practical position-sizing process begins with the amount the trader is willing to lose—not with the maximum leverage displayed on the platform.
Suppose an account contains $10,000 and the trader decides that the maximum acceptable loss on one setup is 1%, or $100.
If the BTC entry price is $100,000 and the stop-loss is $99,000, the distance to the stop is 1%. The trader should calculate a position size that would lose approximately $100 if the stop is reached, allowing for fees and slippage.
Only after determining the position size should the trader choose leverage. If 150× creates a liquidation price too close to the stop-loss, the trader can reduce leverage, reduce the notional position, or avoid the trade.
This approach separates three different decisions:
- How much account equity can be risked?
- How large should the position be?
- How much margin should be committed?
Confusing these decisions is one of the most common causes of avoidable losses in leveraged trading.
Use Phemex’s Built-In Margin and Risk Calculator
Before confirming a BTC or ETH futures order, traders should use the Phemex order preview and risk tools to review:
- Required initial margin
- Estimated liquidation price
- Position value
- Leverage level
- Maintenance-margin requirements
- Potential fees and funding impact
If the estimated liquidation price is uncomfortably close to the planned stop-loss, the position may be too large for current market conditions.
Phemex’s interface allows traders to adjust leverage and position parameters before submitting the order. This makes the order preview an important final checkpoint rather than a purely administrative step.
Risk Management Checklist for 150× Leverage
Before opening a high-leverage BTC or ETH position, ask:
- Is the trade based on a tested setup or a spontaneous market reaction?
- What is the exact dollar amount I can afford to lose?
- Where is the trade invalidated?
- Is the stop-loss outside normal market noise?
- Does the estimated liquidation price leave enough room?
- Am I accounting for fees and funding?
- Is cross margin appropriate, or would isolated margin limit contagion?
- Would a lower leverage level produce a more resilient position?
- Have I checked the latest contract risk limits?
High leverage should be treated as a precision instrument. It is most useful when the trader already understands the strategy, the contract mechanics, and the maximum acceptable loss.

Frequently Asked Questions
Did Phemex increase BTC and ETH futures leverage to 150×?
Phemex has communicated maximum leverage of up to 150× for selected BTC and ETH USDT- and USDC-margined perpetual futures contracts. The applicable level depends on risk-limit tiers and position size.
Does 150× leverage mean a position can fall 150%?
No. Leverage does not allow an asset to fall 150%. It determines how much notional exposure can be controlled with a given amount of margin. A small adverse move can create a large percentage loss on the margin posted.
Is 150× leverage suitable for beginners?
High leverage is generally unsuitable for inexperienced traders because the liquidation buffer is small and losses can accumulate quickly. Beginners should first learn margin, maintenance-margin, mark-price, and liquidation mechanics.
How can I check my liquidation price on Phemex?
Enter the contract, price, position size, leverage, and margin mode in the Phemex trading interface. Review the estimated liquidation price shown in the order preview before confirming the trade.
Trade With More Flexibility, Not Automatically More Risk
The move from 100× to 150× maximum leverage gives BTC and ETH futures traders more flexibility in how they allocate collateral and manage exposure. It does not change the need for disciplined position sizing.
The strongest use of the new limit is strategic: keeping notional exposure aligned with a tested plan while using only the margin that is operationally necessary. Before every order, review the margin requirement, liquidation price, stop-loss distance, and total account risk through Phemex’s built-in tools.
