Funding rate divergence across exchanges creates a cost of carry spread reaching 0.0136 percentage points per 8-hour window on active contracts.
Cross-venue funding rate spreads reach up to 0.0136 percentage points per 8-hour settlement window across major perpetual contracts. Perpetual futures contracts lack an expiration date. To prevent the perpetual contract price from drifting away from the spot index price, exchanges enforce periodic funding payments between traders. Long position holders pay short position holders when funding is positive. Short position holders pay long position holders when funding is negative. The exchange collects no fee from the funding payment itself; capital transfers directly between trader accounts.
This payment acts as an ongoing cost of carry for holding open position notional. A position held across multiple settlement periods accrues funding charges or credits that adjust the net break-even price of the trade. Because local exchange order book liquidity, open interest distribution, and trader positioning differ across venues, funding rates diverge across exchanges for the same underlying asset.
The current normalised 8-hour funding rates and 24-hour trading volumes across BTC, ETH, SOL, SNDK, TRUMP, and XAU show distinct cost distributions across venues.

Across these markets, SNDK exhibits the largest absolute funding spread at 0.0136 percentage points per 8 hours, followed by SOL at 0.0104 percentage points per 8 hours. BTC displays a spread of 0.0043 percentage points between Bitget (+0.0057%) and OKX (+0.0100%).
To evaluate the financial impact of venue selection, consider a long position of 100,000 USD notional on SNDK held for 30 calendar days.
On Bitget, the 8-hour funding rate for SNDK is +0.0273%. Per 8-hour settlement: 100,000 0.000273 = 27.30 USD paid by the long. Daily cost across 3 settlements: 27.30 3 = 81.90 USD. 30-day cumulative cost across 90 settlements: 81.90 * 30 = 2,457.00 USD.
On OKX, the 8-hour funding rate for SNDK is +0.0137%. Per 8-hour settlement: 100,000 0.000137 = 13.70 USD paid by the long. Daily cost across 3 settlements: 13.70 3 = 41.10 USD. 30-day cumulative cost across 90 settlements: 41.10 * 30 = 1,233.00 USD.
Holding the 100,000 USD long SNDK position on Bitget incurs 1,224.00 USD more in carry cost over 30 days compared to OKX.
Now examine a 100,000 USD long position on SOL held for 24 hours (3 settlement windows).
On Bitget, the SOL 8-hour rate is -0.0098%. Per 8-hour settlement: 100,000 0.000098 = 9.80 USD credited to the long. 24-hour total credit: 9.80 3 = 29.40 USD.
On OKX, the SOL 8-hour rate is +0.0006%. Per 8-hour settlement: 100,000 0.000006 = 0.60 USD paid by the long. 24-hour total charge: 0.60 3 = 1.80 USD.
The net variance between holding long SOL on Bitget versus OKX over 24 hours equals 31.20 USD per 100,000 USD notional.
Holding cost decisions must factor in initial entry and exit trading fees. Default published taker and maker schedules for futures contracts dictate entry friction:
| Exchange | Futures Maker Fee | Futures Taker Fee |
|---|---|---|
| Bitget | 0.0200% | 0.0300% |
| Bybit | 0.0200% | 0.0550% |
| MEXC | 0.0000% | 0.0200% |
| OKX | 0.0200% | 0.0500% |
On a 100,000 USD position, opening via taker order costs 30.00 USD on Bitget, 50.00 USD on OKX, 20.00 USD on MEXC, and 55.00 USD on Bybit.
On the SNDK long trade, OKX charges 20.00 USD more than Bitget on taker entry fees (50.00 USD vs 30.00 USD). However, OKX saves the position 40.80 USD per day in funding payments (81.90 USD minus 41.10 USD). The lower funding rate on OKX offsets the higher entry taker fee in less than 12 hours of holding time.
Funding payments directly modify the margin balance of an open position. On a long position paying positive funding, funding deductions reduce available collateral, bringing the liquidation price closer to the market price without any movement in the underlying index price.
For a 100,000 USD position maintained with 5,000 USD initial margin (20x leverage), a 5.0% price move against the position liquidates the margin balance. On Bitget SNDK perps, 30 days of holding costs (2,457.00 USD) absorb 49.14% of the initial 5,000 USD margin balance solely from funding carry. This shifts the effective adverse price movement required for liquidation from 5.0% down to 2.543% over a 30-day holding period.
On OKX SNDK perps, 30 days of holding costs (1,233.00 USD) absorb 24.66% of the initial 5,000 USD margin balance, placing the effective liquidation threshold at a 3.767% adverse price movement.
