How Basis Trade Works
Frequently Asked Questions
What is a basis trade in simple terms?
A basis trade is a way to earn yield from crypto derivatives without betting on whether Bitcoin goes up or down. You buy Bitcoin in the spot market and simultaneously open an equal short position in perpetual futures at 1x leverage. These two legs perfectly cancel each other out — if Bitcoin rises $1,000, the spot gains $1,000 and the short loses $1,000, netting zero from price movement. The income comes from funding payments collected by the short leg every 8 hours when the derivatives market is priced above spot — which happens when most traders are net long.
How does a basis trade work in crypto derivatives?
The basis trade works through two simultaneous positions that offset each other. The long spot leg gains when price rises. The 1x short perpetual leg loses an equal amount when price rises. Combined, the position is delta-neutral — insensitive to price direction. Every 8 hours, the exchange settles funding payments: when the perpetual futures market trades at a premium to spot (positive funding), long perpetual holders pay short holders. The basis trade's short leg collects these payments as income. At 0.05% per 8-hour interval — typical during high-carry bull market periods — the annualized yield reaches approximately 54.75% on deployed capital.
How do traders manage the risks of a basis trade?
The basis trade has three manageable risks requiring specific responses: (1) Funding normalization — monitor funding rate daily; if annualized funding falls below your minimum threshold (e.g., 15-20%), unwind both legs simultaneously and redeploy capital. (2) Exchange counterparty risk — apply the 30% single-exchange rule: never hold more than 30% of total capital in a basis trade on any single exchange, regardless of the funding yield; spread across two or three exchanges. (3) Execution slippage — set limit orders for both legs simultaneously or as close together as possible to minimize the spread between your spot purchase price and your futures short entry price. Do not leg into the trade sequentially if price is moving.
Common Misconceptions About Basis Trade
The basis trade has no risk because the long and short legs cancel out
The long and short legs cancel out price exposure — the position is delta-neutral. But two significant risks remain. First, exchange counterparty risk: both legs are claims on the same exchange; if the exchange becomes insolvent, both positions are affected regardless of their delta-neutral structure. The FTX collapse affected basis traders running positions on that exchange identically to directional traders. Second, funding rate normalization risk: if funding turns negative, the short leg pays rather than collects, converting the strategy from income-generating to cost-incurring. The basis trade is lower risk than directional leveraged trading, but it is not risk-free.
The basis trade can be run at leverage above 1x on the short leg for higher returns
The 1x leverage on the short perpetual leg is the critical structural feature that eliminates liquidation risk. At 1x short, the spot holding perfectly covers any adverse move in the short leg — if Bitcoin rises, the spot gains exactly enough to fund the short leg's margin. At 2x short, the spot can only cover half the short leg's loss on a price advance; the other half creates a real margin deficit that can trigger liquidation. Running the basis trade at leverage above 1x on the short leg introduces directional and liquidation risk that destroys the strategy's bounded-risk property.
A basis trade is only profitable during bull markets when funding is high
While funding is highest and most consistent during sustained bull markets, the basis trade can be profitable any time funding is persistently positive above the minimum threshold. Funding can be elevated during local rallies within bear markets, during periods of high retail speculation, or during any market environment where perpetual futures trade at a sustained premium to spot. The decision criterion is the current annualized funding rate relative to the minimum acceptable yield — not the prevailing market trend. Conversely, a raging bull market with zero or negative funding generates no income from the basis trade.
