Covered call writing turns your idle BTC and ETH holdings into a recurring income stream. By selling out-of-the-money calls against your spot crypto, you collect premiums month after month while still holding your underlying assets. For Indian crypto investors on CoinSwitch Pro, covered calls are one of the most accessible and reliable ways to extract yield from a long-term position.
This guide explains how covered calls work, what realistic annual yields look like in INR, and how to manage the position when BTC rallies past your strike.
What Is a Covered Call and How Does It Work?
A covered call is a two-position strategy. You own the underlying crypto (spot). You sell a call option against it.
You Own the Crypto, You Sell the Right to Buy It at a Fixed Price
By selling the call, you give the buyer the right (but not the obligation) to buy your crypto at the strike price by the expiry date. You collect the premium upfront.
If BTC stays below the strike at expiry, the call expires worthless. You keep the premium and your BTC.
If BTC rises above the strike, the call is exercised. Your BTC is sold at the strike. You receive the strike value in INR plus the original premium.
Covered Call Payoff Diagram in INR
BTC at ₹65,00,000. Sell a one-month ₹68,00,000 call for ₹4,500 premium.
- If BTC closes at ₹65,00,000 at expiry: call expires worthless. You keep ₹4,500 premium and your BTC. Net gain: ₹4,500.
- If BTC closes at ₹66,50,000: call expires worthless. You keep ₹4,500 and your BTC, which is now worth more. Net gain: ₹4,500 plus appreciation.
- If BTC closes at ₹68,00,000: call expires roughly at the money. Your BTC may or may not be called away. Premium kept.
- If BTC closes at ₹70,00,000: call is exercised. Your BTC is sold at ₹68,00,000. You receive ₹68,00,000 + ₹4,500 premium = ₹68,04,500. You missed the ₹2,00,000 rally beyond your strike.
- If BTC closes at ₹60,00,000: call expires worthless. You keep the ₹4,500 premium but your BTC has lost ₹5,00,000 in value. Net loss: ₹4,95,500. The premium offsets some of the loss but does not protect against a crash.
The premium is income. The strike defines where your upside caps.
How Much Income Can You Actually Earn?
Realistic numbers.
Real Example: 0.1 BTC: Selling Monthly Call: ₹X Premium
Suppose you hold 0.1 BTC (worth ₹6,50,000 at ₹65,00,000 BTC price). Each month, you sell a 0.1 BTC call at a strike 5% above spot (roughly 0.25 Delta).
Typical premium: ₹4,500 to ₹6,500 per month, depending on IV.
Over 12 months at ₹5,500 average: ₹66,000 per year.
Annualised yield: ₹66,000 on ₹6,50,000 = approximately 10.2% per year purely from covered calls, assuming the strike is rarely breached.
This is a strong yield for an asset that produces no native cash flow. It does come with the trade-off of capped upside above the strike each month.
Annualised Yield from Covered Calls in High vs Low IV Markets
High IV environments (IV Percentile above 70): premiums are rich. Annualised yields can reach 12% to 18% on BTC covered calls.
Low IV environments (IV Percentile below 30): premiums are thin. Annualised yields fall to 4% to 7%.
This is why volatility-aware traders run covered calls more aggressively in high-IV regimes and lighter in low-IV regimes.
Choosing the Right Strike Price
Strike selection is the most important decision.
Delta 0.20-0.30 Strikes: The Sweet Spot for Income vs Upside
A 0.20 to 0.30 Delta call is typically 5% to 10% OTM. Premium is meaningful, the probability of being called away is moderate.
This range balances income generation with reasonable upside participation. It is the standard choice for most covered call programmes.
What Happens If BTC Rallies Past Your Strike
If your call goes ITM near expiry, you have three choices.
Let it be called away. Your BTC is sold at the strike. You move to cash and re-enter when you want.
Buy back the call early. You take a small loss on the option (the premium has grown), but you keep your BTC. Useful if you have a renewed bullish view.
Roll up and out. Buy back the current call and sell a higher strike, later-expiry call. Often you can roll for a small additional credit.
Choosing the Right Expiry
Expiry selection is the second key decision.
Weekly vs Monthly: More Income vs Less Management
Weekly options earn premium fast (annualised yield can be higher). They also require constant management (52 cycles per year instead of 12).
Monthly options are the most popular choice. Reasonable yield, modest management overhead, decent risk-adjusted returns.
Quarterly options earn less per unit time but are easier to manage if you prefer a hands-off approach.
Theta Decay Curve: Why Shorter Expiry Earns Faster
Theta decay accelerates as expiry approaches. Roughly two-thirds of an option’s time value evaporates in its final week. This is why selling weeklies feels lucrative on a per-unit-time basis.
The catch: weekly options also have higher Gamma. A sharp BTC move in the final days can put a previously safe short call deep ITM. The trade-off is real.
Step-by-Step: Selling a Covered Call on CoinSwitch Pro
The execution workflow.
How to Place the Covered Call Order
Confirm you hold the underlying. CoinSwitch Pro will not let you sell a covered call without sufficient BTC or ETH in your account.
Open the BTC options chain. Select your expiry (monthly is the standard starting point). Find a strike at your target Delta (0.20 to 0.30 OTM).
Tap SELL on the call side. Enter quantity matching your spot holding (one 0.1 BTC contract per 0.1 BTC of spot). Confirm the premium collected and net debit/credit (you should see a net credit).
Submit. The premium appears in your account immediately.
Managing the Position: Roll, Close, or Let Expire
Set a calendar reminder for one week before expiry. Check the position.
If the call is well out of the money (Delta below 0.10): let it expire worthless. Keep the premium.
If the call is in the money (Delta above 0.40): decide between rolling or accepting assignment.
If the trade has reached 50% of max profit before expiry: consider closing early to lock in the gain and free up the BTC.
Risks and Limitations of Covered Calls
The strategy is not risk-free.
You Miss Out on Big Rallies Above Your Strike
The fundamental cost of covered calls. If BTC rallies 30% in a month, you miss most of it. Your BTC is called away at the strike (5% above spot) and you keep only the premium.
This is acceptable for steady-yield holders. It can be painful for bulls who underestimated the move.
The Option Can Be Exercised Against You (How CoinSwitch Handles This)
Most crypto options on CoinSwitch Pro are cash-settled European-style, meaning early exercise is not possible. Settlement happens at expiry based on the index price.
Verify the contract specifications before trading. Different contracts may have different settlement rules.
Tax on Covered Call Premium Income in India
Premium income is taxable.
The premium received at the time of sale is not immediately taxable in the strict sense. The taxable event is when the option is closed or expires.
If the call expires worthless: the full premium is realised as a gain at expiry. Under Section 115BBH (conservative interpretation), this is taxed at the flat 30% VDA rate. Under business income classification (if applicable), slab rates may apply.
If the call is exercised: the BTC is sold at the strike. Both the spot sale (potentially a VDA gain) and the option close (premium realised) are taxable events.
If the call is closed early: the difference between the premium received and the premium paid to close is the realised gain or loss.
The 1% TDS rule applies on the gross proceeds of each option transaction.
For Indian covered call programmes, the cumulative tax friction across 12 months can be significant. Account for it when calculating net yield.
Key Takeaways
Covered call writing is a high-quality income strategy for Indian crypto holders who already own BTC or ETH. Realistic annualised yields range from 6% to 15% depending on IV regime and strike choice.
The trade-off is capped upside above the strike each month. For long-term holders who do not need to hit BTC’s absolute high, this is a fair exchange. For aggressive bulls expecting moonshots, covered calls are too conservative.
CoinSwitch Pro’s options chain and Strategy Builder make execution straightforward. Set monthly expiries, sell at 0.20 to 0.30 Delta strikes, manage at 50% max profit or 21 days to expiry. Account for the 30% VDA tax friction in your expected return calculation.
FAQs
Q: How much BTC do I need to start a covered call programme? You need at least the underlying quantity for one contract (typically 0.01 to 0.1 BTC per contract on CoinSwitch Pro). Start with one contract to learn the workflow before scaling.
Q: Can I run covered calls on ETH too? Yes. ETH covered calls are popular and ETH IV is usually higher, giving better premiums per rupee invested. Same mechanics apply.
Q: What if BTC crashes after I sell the call? The call expires worthless. You keep the premium. Your BTC has lost value but the premium partially offsets the loss. Covered calls are not a hedge against major crashes.
Q: How is covered call income taxed? Premium is realised at expiry or close, taxed at 30% under Section 115BBH (conservative interpretation). 1% TDS applies on gross proceeds.
Q: Should I sell weekly or monthly calls? Monthly is the most common for retail investors. Weekly earns faster but requires more management. Quarterly is hands-off but earns less per unit time.
Q: What does “rolling a covered call” mean? You buy back the current short call and sell a new call at a different strike and/or expiry. Usually done to defer assignment when BTC rallies near your strike.
Q: Is the premium I collect immediately spendable? The premium appears in your account immediately. The taxable event happens at expiry or close. You can spend the cash but be aware of the eventual tax liability.
