Funding Arbitrage Explained: Opportunity, Cost and Risk

Funding arbitrage usually means trying to earn funding payments while hedging directional price risk. A common example is holding a spot asset while shorting a perpetual future when funding is strongly positive. In theory, the trader collects funding while price exposure is partially offset.

Simple example

If BTC perpetual funding is positive, a trader might buy spot BTC and short BTC perpetual futures. If the hedge is balanced, price changes on the spot position and short futures position may offset each other, while the short futures side receives funding.

Important costs

• Trading fees for entry and exit.
• Spread and slippage.
• Borrowing or margin costs.
• Withdrawal or transfer delays between venues.
• Risk of funding changing before the trade earns enough to matter.

Risks people underestimate

Funding can flip quickly. Liquidity can disappear. Exchanges may have different index prices, contract specifications, and margin rules. A hedge that looks neutral on paper may behave differently in stressed markets.

When spreads matter

Cross-exchange funding spreads are useful because they show where traders are paying different premiums for similar exposure. But the highest spread is not automatically the best trade. Execution, fees, account limits, and exchange risk must be considered.
