Covered call: Earn premium while capping upside

A covered call combines long exposure to an underlying asset with a short (sold) call option on the same underlying and quantity. The seller receives a premium upfront, which can partially offset a decline in the long position. In return, the strategy gives up additional net upside beyond the strike price at expiration. In a traditional covered call, the long exposure may come from holding the asset itself. Bybit’s Covered Call preset uses the same basic idea, but pairs the short call with a supported long futures position rather than a Spot holding.

Key Takeaways:

• A covered call exchanges some potential upside for the premium received from selling a call against long exposure to the same asset.

• Strike and expiry determine how much upside is retained, how much premium is received and how long the obligation remains open.

• Bybit's Covered Call preset pairs a supported long futures position with a short call; the option settles separately in USDT and does not automatically close the futures leg.

How does a covered call work?

The covered call strategy has two legs that move in opposite directions above the strike:

• Leg 1 — Long exposure: You hold a long position in the underlying asset, such as a BTCUSDT Perpetual contract. This leg profits when the price rises and loses when it falls.

• Leg 2 — Short call: You sell a call option on the same asset with matching quantity. As the seller, you receive the premium and take on the obligation to pay the buyer the intrinsic value if the option finishes in the money at expiration.

When the underlying price stays below the strike, the call expires worthless and you keep the full premium alongside your long position. When the price rises above the strike, the short call offsets additional gains, capping the combined payoff. The premium does not remove downside risk: if the underlying falls sharply, you still bear the loss on the long position, reduced only by the premium.

How do strike and expiry shape a covered call?

For a given underlying and expiry, the strike you choose sets the boundary between retained upside and premium income.

• Out-of-the-money call (strike above the current price): Retains more upside before capping, but earns a smaller premium, all else equal.

• At-the-money call (strike near the current price): Balances premium income against upside retention.

• In-the-money call (strike below the current price): Generates the most premium, all else equal, but caps the combined payoff immediately.

Expiry works alongside the strike. A later expiry generally carries a higher premium, all else equal, because the underlying has more time to move. However, the obligation to forgo upside beyond the strike also lasts longer. Choosing an expiry involves balancing income against the period during which upside is capped.

Worked example: covered call payoff at expiration

Assume BTC is trading at $50,000 when you establish the position.

• Long futures position: 0.1 BTC of BTCUSDT Perpetual entered at $50,000

• Short call: 0.1 BTC option quantity, strike $55,000

• Premium received: $800 per BTC × 0.1 = $80

Assume the futures position remains open through option expiration and is not liquidated. The example uses the same BTC price for futures P&L and option settlement and excludes trading fees, funding and other costs.

• Maximum gain at expiration: (Strike − Entry price) × Quantity + Premium = ($55,000 − $50,000) × 0.1 + $80 = $580. This is reached when the settlement price is at or above the strike.

• Breakeven at expiration: Entry price − (Premium ÷ Quantity) = $50,000 − ($80 ÷ 0.1) = $49,200. Below this level, the combined position produces a net loss.

• Simplified downside at expiration: If the futures position remains open and BTC settles at zero, the combined result would be −$4,920 before fees and funding. In practice, a leveraged futures position may be liquidated earlier if margin requirements are not maintained.

These results describe the payoff at expiration. Before expiry, the position's value can change due to price movement, time decay, implied volatility shifts and liquidity conditions.

How the strategy settles on Bybit

Bybit Options are European-style and cash-settled in USDT, so an in-the-money short call settles as a cash payment rather than through physical delivery of the underlying. The futures leg remains a separate position and is not automatically closed when the option settles.

In the Bybit Covered Call preset, the long leg is a supported futures contract while the short leg is a call option with matching exposure. The two legs interact economically but remain separate positions with their own P&L and margin mechanics.

This means the capped payoff shown in the worked example assumes the futures position remains open through option expiration. A futures position carries its own margin and liquidation risk before then, so the theoretical expiration payoff does not guarantee the account will reach that outcome.

How to set up a covered call on Bybit

The route depends on the market you want to trade. For crypto Options, start from Trade → Options. For Perp Options on TradFi assets, start from TradFi → Options. The strategy setup is otherwise similar.

On the Bybit App, switch to Pro mode and open Strategies. Select Covered Call, then tap on Trade Now to configure the strategy.

Choose an expiry, then select the futures contract for the long leg. If you're trading crypto options, the App currently supports USDT Perp, USDC Perp and USDT Futures. Set the leverage and quantity for the futures position, then choose the strike and matching quantity for the short call.

Review the payoff, displayed maximum profit and total margin before tapping Create Strategy. On the confirmation screen, check both legs, their quantities, the option expiry and the margin information before confirming the order. Note that changing the futures leverage affects all positions and active orders for the current pair.



Benefits and risks of a covered call

Benefits:

• Premium income. The premium is received upfront when the call is sold, regardless of what happens at expiration.

• Partial downside offset. The premium reduces the effective entry price, lowering the breakeven.

• Flat or moderately bullish markets. If the price stays near entry, the premium can improve the combined result compared with the long futures position alone, before fees and funding.

Risks:

• Capped upside. If the underlying rallies well past the strike, the additional gains are forfeited. The combined payoff is fixed at the maximum gain.

• Continued downside exposure. The premium cushions only a small portion of a large decline.

• Margin and liquidation risk. The Bybit Covered Call preset includes a futures position and a short call. Both contribute to the strategy's margin requirements, and adverse moves can lead to liquidation if sufficient margin is not maintained.

• Early exit cost. Closing the short call before expiry means buying it back at the current market price, which may be higher than the premium received. The bid-ask spread and fees add to the cost.

When might a covered call be suitable?

The strategy is often used when you expect the price to stay flat or rise modestly. In that scenario, the premium adds income the long position alone would not generate. A covered call may be less suitable if you expect a strong rally or cannot maintain the required margin.

The bottom line

A covered call lets you earn premium income while accepting a limit on potential upside. On Bybit, the strategy pairs a long futures position with a short call, allowing you to benefit from a flat or moderately rising market. However, the premium isn't a free gain. The option settles separately without automatically closing the futures leg, and margin and liquidation risks remain. The key is knowing how much upside you're willing to give up and whether you can manage the risks along the way.
