Divergent funding rates and exchange fee tiers create significant holding cost variances for identical perpetual positions over 30 days.
Divergent funding rates across exchange order books create holding cost spreads up to 3.393% per 30 days for identical long positions.
Perpetual futures contracts use periodic funding payments to tether contract prices to spot index prices. Every eight hours, open positions settle funding payments directly between long and short market participants. When contract prices trade at a premium to the spot index, long position holders pay shorts. When contract prices trade at a discount, short position holders pay longs.
Each venue operates an isolated order book with independent depth and market participant skew. Local contract premiums drift apart across venues as a result. A long position on a venue with a negative funding rate receives payments from short position holders. The identical long position held on a venue with a positive funding rate pays short position holders every eight hours.
Trading fees apply upon opening and closing a position. Maker and taker fees represent fixed transactional drag. Over extended holding periods, cumulative funding payments dominate total holding friction.
The following tables list normalized 8-hour funding rates and default fee schedules across venues using current market figures.

A 30-day holding window contains 90 funding cycles of eight hours each. Evaluating a $100,000 long position opened and closed via default taker market orders isolates venue-level holding variance over 90 cycles.
On OKX, the SNDK 8-hour rate is +0.0377%. Over 90 cycles, funding paid equals: 90 0.000377 $100,000 = $3,393.00
OKX default futures taker fee is 0.0005 ($50.00 per $100,000 order). Roundtrip taker execution costs: 2 0.0005 $100,000 = $100.00
Total 30-day friction on OKX = $3,393.00 + $100.00 = $3,493.00
On Bitget, the SNDK 8-hour rate is +0.0000%. Over 90 cycles, funding paid equals: 90 0.000000 $100,000 = $0.00
Bitget default futures taker fee is 0.0006 ($60.00 per $100,000 order). Roundtrip taker execution costs: 2 0.0006 $100,000 = $120.00
Total 30-day friction on Bitget = $0.00 + $120.00 = $120.00
Holding the SNDK long position on OKX instead of Bitget costs an additional $3,373.00 per $100,000 notional over 30 days.
On Bitget, the ETH 8-hour rate is +0.0085%. Cumulative 30-day funding paid equals: 90 0.000085 $100,000 = $765.00
Bitget roundtrip taker execution fee equals: 2 0.0006 $100,000 = $120.00
Total 30-day friction on Bitget = $765.00 + $120.00 = $885.00
On MEXC, the ETH 8-hour rate is -0.0005%. The negative rate generates a credit for the long position. Cumulative funding received equals: 90 0.000005 $100,000 = $45.00
MEXC default futures taker fee is 0.0002 ($20.00 per $100,000 order). Roundtrip taker execution costs: 2 0.0002 $100,000 = $40.00
Net 30-day position cost on MEXC = $40.00 fees - $45.00 funding credit = -$5.00 net cost (a $5.00 net credit to the margin account).
Holding the ETH long position on Bitget instead of MEXC costs an extra $890.00 per $100,000 notional over 30 days.

Funding rate calculations assume static rates across the entire 30-day window. In active markets, rate adjustments occur every eight hours based on order book changes. Ongoing funding debits subtract directly from available maintenance margin. Unfavorable funding rate divergence drains margin balances, moving liquidation prices closer to the current mark price without any movement in underlying index prices.
