Funding Rate vs Basis in Crypto Derivatives

Funding rate applies to perpetual contracts that have no expiry. Basis compares a dated futures price with the spot price. Both can describe positioning, but they answer different questions.

Funding rate in plain language

Perpetual contracts use periodic payments between long and short holders to keep the contract near the reference price. A positive funding rate generally means longs pay shorts; a negative rate generally means shorts pay longs. The exact calculation and interval depend on the venue.

Basis in plain language

Basis is the difference between a futures price and the spot price, often expressed as a percentage. A positive basis means the futures contract trades above spot; a negative basis means it trades below spot. The expiry date, financing conditions, and contract specification matter.

When the signals disagree

• Positive perpetual funding with a small dated-futures basis can indicate leverage is concentrated in perps rather than the full futures curve.
• A positive basis with neutral funding can reflect term financing or institutional carry rather than crowded perpetual longs.
• A negative funding rate during a rising spot market can mean shorts are paying while price strength is being led by the cash market.

How to report the signal responsibly

1. Name the venue, contract, interval, and observation time.
2. Pair derivatives data with spot price, volume, and open interest.
3. Describe positioning as an observed condition, not a guaranteed future outcome.
4. Include a risk note when the page could be read as a trading recommendation.
