Crypto Futures and Basis

Besides perpetual swaps, crypto trades through dated futures that expire on a fixed date, such as monthly and quarterly contracts. They are listed on regulated exchanges like CME and on crypto native exchanges. Because dated futures converge to spot at expiry, the difference between the futures price and the spot price, the basis, tells traders how much the market is paying to hold leveraged long exposure. Crypto basis has at times been far larger than in traditional markets, creating popular arbitrage trades.

Where crypto futures trade#

Basis and annualised basis#

basis = futures price - spot price
annualised basis = (futures / spot - 1) × (365 / days to expiry)

Why crypto basis is often high#

In traditional markets, arbitrage keeps futures close to spot plus financing costs. In crypto, basis has often been higher because:

• Demand for leverage: many traders want long exposure without paying full price.
• Limited arbitrage capital: institutions face custody, capital and regulatory hurdles.
• Counterparty and exchange risk: arbitrageurs demand compensation.

In the 2021 bull market, annualised Bitcoin basis on some exchanges exceeded 30% at times. In bear markets, it has dropped near zero or turned negative. See Contango.

Basis as a sentiment signal#

Basis and perpetual funding rates usually move together. See Funding Rates.

CME basis and ETFs#

After US spot Bitcoin ETFs launched in January 2024, many hedge funds bought ETF shares and sold CME futures to capture the basis, a regulated version of the cash and carry trade. Changes in CME basis and open interest became closely watched indicators of institutional activity. See Cash-and-Carry Arbitrage.

Rolling dated futures#

Holders of dated futures must roll before expiry to keep exposure, selling the expiring contract and buying a later one. In contango, rolling long positions costs money; in backwardation, it earns money. See Rolling Futures Contracts and Roll Yield.

Perps vs dated futures#

Risks#

• Basis can widen or collapse before expiry, causing mark to market losses.
• Exchange and custody risk on crypto venues.
• Margin calls on the short futures leg in sharp rallies.
• Settlement differences between reference rates and spot.

Frequently asked questions#

What is basis in crypto futures?#

The difference between a dated futures price and the spot price, often expressed as an annualised percentage.

Why do crypto futures trade above spot?#

Mostly because of strong demand for leveraged long exposure and limited arbitrage capital, plus financing costs.

How do you annualise the basis?#

Divide the futures price by spot, subtract 1 and multiply by 365 divided by the days to expiry.
