Holding identical perps across venues costs up to $2,358 monthly per $100k
Live funding rate spreads create a 30-day holding cost gap of up to $2,358 per $100,000 position across major perpetual exchanges.
Holding a long position on Bybit, OKX, Bitget, or MEXC incurs starkly different cumulative holding costs due to baseline funding rate divergence. On a $100,000 long position in SNDK, the spread between the cheapest and most expensive exchange yields a holding cost differential of $2,358 over 30 days.
Perpetual contract funding rates settle every eight hours, totaling 90 settlement periods across a 30-day month. When funding is positive, long position holders pay short position holders. While execution fees are charged twice (once on entry and once on exit), funding fees compound continuously across the entire holding duration. Exchange funding algorithms sample index premium and interest rate differentials independently, generating persistent structural spreads between order books on identical underlying assets.

Execution Fee Amortization vs Funding Drag
Execution fees are fixed upfront transactions. Funding payments compound across time.
On Bybit, opening and closing a $100,000 taker position incurs a combined 0.1100% in execution fees ($110.00). On MEXC, the same round trip incurs 0.0400% ($40.00). The execution fee variance is $70.00.
On SOL, MEXC charges 0.0030% per 8 hours ($3.00 per interval per $100k nominal), whereas Bybit charges 0.0067% ($6.70 per interval per $100k nominal). The funding rate spread is $3.70 per 8 hours ($11.10 per day).
After 7 funding intervals (56 hours), the funding rate savings on MEXC ($25.90) combined with lower entry fees offset Bybit's execution structure. By day 30, cumulative SOL funding payments total $270.00 on MEXC versus $603.00 on Bybit, generating a net spread of $333.00 in favor of MEXC despite initial execution costs.
Margin Decay and Liquidation Mechanics
Funding charges reduce available account margin directly. For positions carried at elevated leverage, funding debits shift liquidation price levels closer to current market prices over time.
At 20x leverage on a $100,000 position, initial margin requirement is $5,000. An adverse index movement of 4.50% brings the account balance to liquidation thresholds depending on maintenance margin rates.
If a position incurs 2.3580% in cumulative funding drag over 30 days (such as SNDK on Bybit), $2,358.00 is deducted from account equity. On $5,000 initial margin, funding payments consume 47.16% of collateral. This deduction shifts the effective liquidation point from a 4.50% adverse market move down to an approximate 2.14% move.
