Phemex review

What Phemex is

Phemex was founded in 2019 by eight former Morgan Stanley executives. They came from systems engineering. Jack Tao led the team at first. The team built the platform around four things. The first is low-latency matching. The second is REST and WebSocket API docs at pro depth.

The third is sub-account management as a standard feature. The fourth is demo trading against live market data. That engineering background shows all through the product.

Sub-account support is not standard at this tier. On Phemex, a trader can run more than one strategy in separate accounts under one master login. Each account has its own risk settings. A trader can give collaborator access and still hide the master balance. PnL does not mix across books.

Some traders run several strategies at the same time. One example is a BTC trend-following account plus a separate altcoin mean-reversion account. For these traders, the account setup removes the friction of separate logins. Mixed positions in one margin pool are no longer a problem. See Phemex's current open interest and volume on PerpFinder.

Fees in detail

Phemex's contract fee schedule starts at 0.01% maker and 0.06% taker on USDT-margined perpetual futures. The 0.01% maker rate ties with WhiteBIT for the lowest on this list.

The rate is half the 0.02% charged by Binance, OKX, and Bybit. The taker rate of 0.06% is above average. At base level, it matches KuCoin and Bitget.

The fee page sets the futures level by 30-day volume:

• Standard (default, 30-day volume under 8M USD): 0.01% maker, 0.06% taker
• VIP 1 (8M USD 30-day volume): 0.008% maker, 0.055% taker

The Phemex Token (PT) gives a 10% discount on futures fees. The discount needs no minimum volume. The Market Maker Incentive Program offers up to -0.005% maker rebates for qualifying makers.

Take a $10,000 BTC/USDT round-trip that opens and closes at market. The base taker cost is $12.00 on Phemex. KuCoin and Bitget charge the same. Now take a $10,000 round-trip that opens and closes on limit. The maker cost is $2.00 on Phemex and $4.00 on Binance. Some strategies run mainly on limit orders.

Examples are grid strategies, mean-reversion entries and algo maker logic. For these strategies, Phemex's 0.01% maker rate saves $2 per $10k round-trip compared to Binance. At $500k daily limit-order volume, the saving is $1,000 per day. Model your own mix at the fee calculator.

Security and proof of reserves

Phemex publishes monthly Merkle tree Proof of Reserves. The May 2026 PoR report confirmed a total reserve ratio of 131%. BTC was at 133%, ETH at 142%, USDT at 104%, and SOL at 156%. On 2026-09-26 the Proof of Reserves page showed BTC at 104.00%, ETH at 121.50% and SOL at 148.40%.

That page shows no snapshot date. The exchange states that it does not lend, borrow, or rehypothecate customer funds. No corporate loans are secured against user assets.

Custody runs through Fireblocks. Fireblocks is an MPC platform. Large asset managers, ETF custodians, and banks use it. Fireblocks is not cheap. Firms that must document their security stack to auditors use it. The choice of Fireblocks signals a design built on pro-grade standards, not on cost cutting.

On January 23, 2025, attackers hit the Phemex hot wallets. Phemex stopped deposits and withdrawals. Its incident post says Phemex restored all withdrawals in February 2025. The post gives no loss amount. The Terms of Use name one group company in Poland and no licence.

Singapore law governs the terms. No MAS Digital Payment Token license exists. Phemex does not serve US residents. Phemex has no FCA or CFTC licensing. The PerpFinder team cross-checked Phemex's PoR portal in May 2026. BTC reserve ratios were above 100%.

Leverage and pairs

Phemex lists over 200 perpetual futures pairs. Max leverage is 150x on the BTC/USDT perpetual. The inverse BTCUSD contract allows 100x. Phemex lists both USDT-margined linear contracts and inverse (coin-margined) contracts. Traders can post BTC and ETH as collateral on inverse contracts.

Crypto holders can then skip the USDT conversion. Leverage steps down for smaller-cap assets and at larger notional sizes. The position tier table sets these steps.

Phemex lists copy trading with risk limits that you can set per position. The premium membership program gives zero-fee spot trading for a flat monthly fee. The program is useful for traders who run spot next to their futures. Phemex lists native grid bots and DCA bots for range-bound and build strategies.

The REST and WebSocket API has docs at pro standards. The docs cover order types, account management, sub-account access, and position streaming. Some algo teams need well-kept API docs but do not want to pay pro minimum volumes to get them. Phemex is a good fit for these teams.

How it compares

In PerpFinder's daily snapshot on 2026-09-04, Phemex's 24-hour perp volume was 0.9% of Binance's. The figure is one dated observation, not a trend. Order book depth on BTC and ETH is fine for positions under $100k notional. Below the top 30 assets by market cap, open interest thins and spreads widen.

Two numbers define Phemex pricing on a $10k round-trip. The first is $12.00 at market. That cost is level with KuCoin and Bitget and $2 above Binance. The second is $2.00 on limit orders, half of Binance's $4.00 maker cost.

The inversion makes Phemex worth a look for any strategy that avoids market orders. Check the cost comparison tool for side-by-side scenarios at your usual order type mix.

Who Phemex is for

Algo traders who work mainly on limit orders: these traders want the lowest possible maker fee. They do not want to lock capital in exchange tokens. Phemex's 0.01% maker rate is the most direct path to that goal, alongside WhiteBIT.

Traders who run more than one strategy and need sub-accounts: Phemex's sub-account tools are more developed than what Bybit or OKX gives to non-pro accounts. A small trading desk may manage 3-5 separate strategy books. For that desk, Phemex handles account-level splits natively.

Traders who mainly use market orders, need US account access or need pro depth: Binance, Bybit, or Hyperliquid fit better on each of those points.
