Hyperliquid Funding Arbitrage: Carry Trade Risks
How a spot-and-perp funding carry trade on Hyperliquid works and the costs and risks that make it far from risk-free.
Direct answer
A funding carry trade holds spot and an offsetting short perp to collect positive funding while staying roughly price-neutral. It is not risk-free. Four trading fees, slippage, basis moves, changing funding, and liquidation risk on the perp leg can erase the carry. Work out the cost break-even first, then ask what happens if funding turns negative.
In short
- 1Carry is collected only while funding stays favourable.
- 2Entry and exit cost four fees, which sets a break-even holding time.
- 3The perp leg can be liquidated even when the combined position looks neutral.
How does the trade work?
Buy spot, short the same size in the perp. If funding is positive, the short receives it. Price moves roughly cancel, leaving the funding as the return. The structure is a hedge, not a guarantee.
What does it cost to run?
Opening and closing both legs is four trades. At the base tier a taker spot trade is 0.070% and a taker perp trade is 0.045%, so a full taker open and close costs 0.23% of notional before slippage. Funding collected must exceed that to profit.
At a hypothetical 0.001% paid per hour, 0.23% takes about 230 hours of carry to recover. The rate you actually receive may be lower or reverse.
What can go wrong?
Funding can flip sign. The spot and perp prices can diverge, a basis risk. The perp leg uses margin, so a sharp rally can push a short toward liquidation even though the spot leg gains. Maintenance margin and mark price decide that, not your net exposure.
- Funding changes sign: you pay instead of receive.
- Basis moves between the spot and perp price.
- Margin on the short leg is liquidated in a spike.
- Slippage on a thin spot or perp book.
How do I model it safely?
Enter all four fees, a slippage estimate, a conservative funding path, and a liquidation buffer. The HYPE carry calculator on this site does this for HYPE, and it never describes the result as risk-free or expected profit.
Example: a $20,000 carry on paper
Say you buy $20,000 of spot and short $20,000 of perp, and funding pays 0.0008% per hour to the short. That is $0.16 an hour, or $3.84 a day. A taker open and close at the base tier costs 0.23%, or $46.00, before slippage.
It takes about 12 days of unchanged funding to repay $46 of fees, and only if the rate does not move. If it turns negative on day three, the trade is a loss. This is an illustration, not an expected return.
Common mistakes
Stress funding to zero and negative, add slippage, and keep enough margin on the perp leg.
- Forgetting the four trading fees.
- Assuming the hedge removes all liquidation risk on the short leg.
- Using the current funding rate as the rate for the whole holding period.
