Funding Rate Arbitrage
Funding rate arbitrage seeks periodic payments between perpetual-futures longs and shorts while using an offsetting position to reduce broad market direction.
Market-neutral arbitrage, capturing price differences while hedging out market direction, is an established institutional trading strategy, not a crypto invention.
For Axis, funding rate arbitrage is not the primary source of yield. The funding trade has been well arbitraged across the industry over many years, so its standalone return has compressed. The desk has deep experience managing it, and it still carries real risk. Its main role at Axis is to hedge the spot inventory held for the bread-and-butter cross-venue and cross-currency strategies, not to serve as a primary revenue driver.
Illustrative structure
When a BTC perpetual has positive funding paid by longs to shorts, a structure can:
buy spot BTC;
short an equal notional amount of the BTC perpetual; and
receive funding on the short perpetual while the long spot position offsets much of the directional exposure.
The two legs are equal at entry in this example. Price changes, contract mechanics, fees, and rebalancing can change the hedge ratio over time.
Funding is not basis
The funding rate is a periodic payment between perpetual-futures longs and shorts. The basis is the price difference between two related instruments, such as spot and a perpetual.
A funding rate strategy can experience gains or losses from basis changes, but its intended return driver is the funding payment. A basis trade instead seeks a change or convergence in the price difference itself.
Residual risks
Positive funding can shrink or reverse. The perpetual can diverge from spot, margin requirements can rise, the short can be liquidated, either leg can fill incompletely, and a venue can restrict trading or withdrawals. Fees, borrow or collateral costs, and rebalancing can exceed funding received.
