Perpetual futures on Hyperliquid pay funding every hour. When longs outnumber shorts, longs pay — and that payment goes directly to whoever is on the other side. The funding rate arbitrage trade is built on one idea: collect that payment with no directional exposure.
The mechanics are straightforward. Buy spot. Short the equivalent amount on the perpetual. You are now delta-neutral — price going up or down does not affect your total position. What remains is the funding rate, paid to you every hour as long as longs keep paying shorts.
This is a crypto-native version of the carry trade that TradFi practitioners will recognise immediately. The TradFiDefi Arbitrage Signal page tracks the annualised yield and basis in real time across all major Hyperliquid perps.
Why Hyperliquid Pays More Often
Most centralised exchanges settle funding every 8 hours. Hyperliquid settles every hour — 24 times per day, 8 760 times per year.
This matters in two ways. First, compounding works in your favour on a shorter cycle. Second, the rate resets to market conditions more frequently, meaning extreme readings correct faster and the signal is more responsive to what the market is actually doing right now.
The annualised yield calculation is simple:
Hyperliquid caps the funding rate at 0.00125% per hour in either direction. At the cap, the annualised yield for the cash-and-carry trade is approximately 11% — collected with no directional exposure, assuming you can execute spot and the perp simultaneously.
The Basis — A Health Check on the Trade
The basis is the difference between the perpetual price (mark price) and the spot reference price (oracle price):
A positive basis means the perp trades at a premium to spot. A negative basis means the perp is cheaper than spot.
The basis and the funding rate are related — funding is the mechanism that pulls the perp price back toward oracle. When funding is high and positive, the perp is expensive relative to spot and longs are paying to hold that premium. When basis is near zero, the two prices are already aligned and funding is likely to moderate soon.
For the arbitrage trade, a large positive basis at entry is an added bonus: not only do you collect the funding rate, but the basis itself is likely to compress back toward zero, delivering additional profit as the perp price falls toward oracle.
Reading the Signal
| Annualised Yield | Signal | Interpretation |
|---|---|---|
| > 10% | Strong | Market at or near funding cap. Clear carry trade opportunity. |
| 3 – 10% | Moderate | Positive carry. Viable if execution costs are low. |
| −3 – 3% | Neutral | Insufficient yield. Execution costs likely outweigh the carry. |
| < −3% | Reverse | Funding is negative. Longs are being paid — market is positioned short. |
The Reverse signal is a different trade. Longs collect funding, but shorting spot requires a borrowing facility most retail traders do not have access to. For most participants, the reverse signal is more useful as a directional indicator — heavy negative funding means the market is crowded short, which often precedes a squeeze.
Risks
Basis risk. If the spot price and perp price diverge significantly during a liquidation event, your hedge may not be perfect for a brief period. This is usually temporary but can cause mark-to-market losses at the worst moment.
Execution risk. The two legs — spot buy and perp short — need to be sized and entered simultaneously. A delay between legs creates momentary directional exposure.
Rate risk. Funding rates change every hour. A yield that looks attractive today can compress to near zero if sentiment shifts. The trade works best when funding has been elevated for a sustained period, not a single spike.
Counterparty risk. Both legs sit on Hyperliquid. This is not a cross-exchange arbitrage — it is a single-venue carry trade. Exchange risk applies to the full position.
Advanced Setup — Using Spot as Collateral on Hyperliquid
The standard trade deploys two separate pools of capital: spot BTC in a wallet and USDC margin on Hyperliquid. The yield on invested capital is roughly half the notional yield because you are funding both legs independently.
There is a more capital-efficient version. Hyperliquid allows you to deposit BTC directly as cross-margin collateral and use it to back a short perp position on the same exchange. The two legs then share the same capital:
The delta neutrality holds in the same way: if BTC drops 10%, the collateral loses 10% in USD terms but the short perp gains 10% in unrealised P&L. The net equity stays roughly flat. The margin ratio remains stable because the perp gain offsets the collateral decline — so the liquidation risk that would normally concern a leveraged position is substantially mitigated here.
The trade-off is exchange risk. In the standard setup, your spot BTC sits in your own wallet. In the collateral setup, the full position is on Hyperliquid. If the exchange experiences a technical issue, a smart contract exploit, or an unexpected halt, both legs are exposed simultaneously. For the standard trade, only the perp margin is at exchange risk.
This is the core decision in sizing the trade: capital efficiency versus custody risk. Many practitioners use the collateral setup for a portion of the position and keep a separate spot allocation in cold storage, effectively blending the two approaches.
