Definition
Basis trading in futures markets refers to strategies that involve exploiting the difference, or the basis, between the price of a futures contract and the price of the underlying asset in the spot market. In the context of cryptocurrency, the underlying asset is typically the spot price of the cryptocurrency itself (e.g., Bitcoin or Ethereum).
This topic is part of the broader pillar page: Introduction to Cryptocurrency Futures.
A futures contract is an agreement to buy or sell an asset at a predetermined price at a specified time in the future. This contrasts with spot trading, where assets are exchanged immediately at the current market price. While perpetual futures contracts (which do not have an expiry date) are common in crypto, basis trading is most clearly defined when applied to traditional futures contracts that have a set expiration date, though the concept still applies to the relationship between perpetual prices and spot prices via funding rates.
Why it matters
The basis is a critical indicator of market sentiment and the relationship between immediate supply/demand (spot) and future expectations (futures).
- Contango: When the futures price is higher than the spot price. This often suggests that market participants expect the price to rise or that there is a premium associated with holding the futures contract, perhaps due to the cost of carry.
- Backwardation: When the futures price is lower than the spot price. This can indicate immediate high demand for the spot asset, or bearish sentiment regarding the future price.
Understanding the basis allows traders to identify potential arbitrage opportunities or hedge existing positions more effectively. For example, if the basis widens significantly, it might signal a temporary dislocation between the two markets that could correct itself.
How it works
The calculation for the basis is straightforward:
Basis = Futures Price - Spot Price
Basis trading strategies often involve simultaneously taking long and short positions to profit from the expected convergence of the futures price and the spot price as the expiration date approaches.
Convergence
As a futures contract approaches its expiration date, its price generally converges toward the spot price of the underlying asset. This is because, at expiration, the futures contract must settle at the spot price.
For example, if a [[Bitcoin futures contract]] expiring in three months is trading at $75,000, and the current spot price of Bitcoin is $73,000, the basis is +$2,000. A trader employing a convergence strategy might enter a trade anticipating that this $2,000 difference will shrink to zero by expiration.
Arbitrage and Hedging
Basis trading techniques often overlap with Arbitrage strategies. If the basis becomes too large (either positive or negative), arbitrageurs might execute trades to capture the difference, which, in turn, helps push the futures price back toward the spot price through market mechanics.
In the case of perpetual futures, the equivalent mechanism to the convergence seen in traditional futures is the funding rate. The funding rate is a periodic payment exchanged between long and short position holders designed to keep the perpetual contract price closely tethered to the spot index price. A high positive funding rate means longs pay shorts, which incentivizes shorting and discourages holding long positions, thus pushing the perpetual price down toward the spot price.
Practical examples
Consider a trader observing a standard futures contract for Ethereum (ETH) expiring next month:
- Current Market Data:
* ETH Spot Price: $3,500 * ETH Futures Price (Next Month Expiry): $3,540
- Calculation:
* Basis = $3,540 - $3,500 = +$40 (Contango)
- Basis Trade Example (Convergence Strategy):
* The trader believes the $40 premium is too high relative to the time remaining until expiration and the cost of carry.
* The trader executes a cash-and-carry trade:
* Short the futures contract at $3,540.
* Long the equivalent amount of ETH in the spot market at $3,500.
* If, at expiration, the spot price is $3,520:
* The futures contract settles at $3,520 (Loss on short futures: $20).
* The spot position is worth $3,520 (Gain on spot long: $20).
* The net result is that the initial $40 basis premium has narrowed to $20, resulting in a profit of $20 per unit, less any transaction fees. This strategy attempts to lock in the initial favorable basis spread.
Common mistakes
- Ignoring Cost of Carry: In traditional markets, holding the physical asset incurs costs (storage, insurance, interest). In crypto, this might relate to the opportunity cost of capital or borrowing costs if using leverage. If the premium (basis) is less than the cost of carry, the trade may not be profitable even if convergence occurs.
- Miscalculating Expiration Convergence: Assuming perfect convergence to the spot price is dangerous. Factors like high volatility or market manipulation close to expiration can cause temporary deviations or unexpected settlement prices.
- Failing to Account for Funding Rates (Perpetuals): When trading perpetual contracts based on basis-like deviations, the trader must constantly account for funding payments. Holding a position against the prevailing funding rate can quickly erode profits through continuous payments.
Safety and Risk Notes
Basis trading, while sometimes framed as lower risk due to simultaneous long and short positions, is not risk-free.
- Basis Risk: The primary risk is that the spread between the futures price and the spot price does not converge as expected, or that it moves further against the trader before expiration.
- Liquidation Risk (Leverage): If leverage is used to magnify the basis capture (e.g., borrowing to fund the spot leg of a cash-and-carry trade), adverse spot price movements can lead to margin calls and liquidation, even if the basis relationship seems favorable overall.

- Exchange Risk: Reliance on two different market venues (one for spot, one for futures) introduces counterparty risk and execution risk, including the possibility of Flash crashes impacting one leg of the trade more severely than the other.
