Funding Rates

BitMEX has permanently delisted 35 derivatives contracts in an orderly early settlement, marking an irreversible step toward its September 23 shutdown and signaling how institutional traders must now manage exit liquidity before forced closures begin in late August. The settlement completed without margin liquidations or settlement fees, but traders still holding positions face punishing forced closures once reduce-only trading begins on August 26.

• BitMEX settled 35 derivatives on July 30 at noon UTC, closing all remaining positions and canceling open orders permanently.
• Reduce-only trading begins August 26, allowing traders only 57 days from settlement to exit positions before forced closures commence.
• The exchange charged no settlement fees and applied lifetime profit/loss directly to user Bitcoin and Tether balances without margin liquidation.

• 35 Derivatives delisted in single settlement, compared to total exchange product suite before shutdown
• Aug 26 Date reduce-only trading begins, 27 days after settlement and 58 days before full shutdown
• Sept 23 Final exchange shutdown date, when all services and remaining positions terminate

BitMEX executed a coordinated delisting of 35 cryptocurrency and financial derivatives on July 30, closing all open positions across tokens, forex pairs, and commodities in what the exchange characterized as an early settlement rather than a forced liquidation event.

The settlement log shows 33 contracts closed at precisely 12:00:05 UTC, with currency pairs EURUSD and USDCHF following moments later at 12:32:25 and 12:33:25 UTC respectively.

This action represents the first major reduction in BitMEX’s product offering since the exchange announced its planned September 23 shutdown, and it establishes a critical timeline for institutional traders managing exposure across the platform’s remaining active markets.

The delisting process unfolded across two distinct phases. Before 04:00 UTC on settlement day, BitMEX fixed the final funding rate, called F0, using reference prices from the preceding eight hours, then halted all new funding calculations and set the next rate to zero. This funding checkpoint established the input for final settlement but did not immediately end trading.

Contracts continued trading until 12:00 UTC, when BitMEX forcibly closed all remaining open positions at the pre-announced 30-minute reference index prices now posted in the exchange’s public records.

The contracts affected included major cryptocurrency pairs like XBTETH at 33.6603, LINKUSDT at 8.4382, and AVAXUSDT at 6.4892, alongside equity indices and currency crosses including GOOGLUSDT (337.83), GBPUSD (1.3379), and USDJPY (162.97).

BitMEX chose settlement fees of zero to avoid margin calls during orderly wind-down

The exchange explicitly rejected the liquidation framework that characterizes distressed exchange failures. Instead of triggering margin calls or charging settlement premiums, BitMEX applied each contract’s lifetime profit or loss directly to user Bitcoin and Tether balances without extracting fees.

This decision to absorb settlement costs internally rather than pass them to traders represents a departure from conventional exchange closure procedures and suggests BitMEX management chose to prioritize an orderly wind-down over revenue extraction during its final two months of operation.

Institutional investors monitoring the closure should note that this zero-fee approach applies only to the 35 contracts delisted on July 30. BitMEX’s regulatory filings and prior announcements indicate that contracts surviving beyond August 26, when reduce-only trading mode activates, will face forced closures under different terms once traders can no longer open new positions.

The distinction matters for portfolio managers tracking cash flows: the July 30 settlement provided final pricing and immediate cash settlement without surprise deductions, but traders holding positions in remaining contracts after August 26 will be forced into closed-only exit conditions with only 58 days to unwind holdings before full platform shutdown on September 23.

The 35 delisted contracts spanned crypto-native assets, traditional equities, forex, and commodities, indicating BitMEX reduced product breadth rather than targeting specific asset classes for early closure.

Reduce-only trading window leaves traders only 57 days to exit before September shutdown

BitMEX’s shutdown timeline now operates under a three-phase framework clearly established by prior exchange communications. Phase one, the early settlement completed July 30, removed 35 derivatives entirely, leaving traders in those contracts with no further exposure.

Phase two begins August 26, when the exchange shifts all remaining contracts to reduce-only trading, meaning traders can only close positions, cancel orders, and withdraw funds, but cannot open new long or short positions. Phase three executes September 23, when BitMEX ceases all services, closes any remaining forced positions at market prices, and ends its operations completely.

For institutional portfolio managers, the August 26 date functions as a hard deadline for strategy adjustment. Any positions held across BitMEX’s remaining contracts after that date will be subject to forced closure mechanics if traders do not voluntarily exit before September 23.

The 27-day window between the July 30 settlement and the August 26 reduce-only activation provides a final period when traders can still adjust hedge ratios, execute synthetic positions, or rebalance across correlated contracts. After August 26, that flexibility disappears: traders lose the ability to establish new positions that might offset existing exposures or to execute calendar spreads.

The regulatory context matters here. BitMEX did not face the kind of solvency crisis or platform hack that forced exchanges like FTX into sudden shutdown. Instead, the exchange appears to have proactively decided to cease operations, giving traders approximately two months from the July 23 announcement to plan their exits.

This orderly approach contrasts sharply with exchanges that collapsed suddenly, offering no settlement windows and leaving traders with immediate margin calls or total loss of funds.

Settlement prices anchored to 30-minute reference indices prevent last-minute manipulation

BitMEX announced in advance which reference indices would determine settlement prices for each delisted contract, allowing traders to monitor the exact pricing mechanism for 24 hours before settlement executed.

The 30-minute reference indices, each designated as a specific BitMEX price feed, established transparent, predictable inputs that removed discretion and prevented exchange operators from manipulating final pricing in favor of particular traders or positions.

This transparency also enabled traders to calculate their exact profit and loss impact before settlement rather than discovering results after the fact.

The exchange fixed funding rates at 04:00 UTC using the preceding eight-hour price window, then froze all further funding rate calculations. This sequence allowed traders to settle any funding obligations and adjust their positions based on known rates rather than facing surprise funding deductions at settlement.

AAVEUSDT settled at 98.249 against its reference index, BRENTUSDT at 87.22, and MSFTUSDT at 428.84, each price now locked into immutable exchange records that traders and compliance teams can audit against reference data.

Locking pricing references 24 hours in advance and posting settlement results immediately in public records prevented the pricing disputes and settlement uncertainty that plague rushed exchange closures.

Institutional traders now face forced closures on remaining BitMEX contracts starting late August

The July 30 settlement eliminated one-third of BitMEX’s product offering, but the exchange continues to operate contracts across the remaining portfolio through September 23. The distinction between settled and surviving contracts becomes operationally critical for any institution maintaining positions across multiple BitMEX pairs.

Traders who exited the 35 delisted contracts during the final trading window received final settlement and cash closure on July 30; traders holding positions in non-delisted contracts face a different exit path.

Between now and August 26, institutions can still actively trade, hedge, and rebalance positions across all remaining BitMEX contracts at full liquidity. After August 26, the reduce-only mode removes that flexibility permanently. Institutional risk managers must now model their exit timing under constrained conditions: reduce-only trading often experiences wider bid-ask spreads and lower liquidity than normal trading, meaning large positions that could exit cleanly during normal conditions may face slippage or partial execution during forced-closure windows.
