A risk reversal is a two-leg options trade that creates a synthetic directional position at low or zero net cost. For Indian crypto traders on CoinSwitch Pro, risk reversals exploit volatility skew to set up bullish or bearish bets that cost almost nothing upfront, with the right structure.
This guide explains both the bullish and bearish versions, breaks down how crypto’s volatility skew makes the trade attractive, and walks through setup on CoinSwitch Pro.
What Is a Risk Reversal?
A risk reversal combines a short OTM option and a long OTM option on opposite sides of the market.
Sell an OTM Put, Buy an OTM Call (Or Vice Versa)
The bullish risk reversal: sell an OTM put, buy an OTM call. The premium from the short put helps fund the long call. You are net long directional, with limited upfront cost but unlimited downside if BTC crashes (the put obligates you to buy at the strike).
The bearish risk reversal: sell an OTM call, buy an OTM put. Mirror image. You are net short directional, with limited upfront cost but unlimited upside risk (the short call has unbounded loss potential).
How It Creates a Synthetic Long/Short with Little Upfront Cost
The trick is that the short option pays for the long option. If the premiums roughly match, you enter the trade at near-zero cost. You get directional exposure for almost nothing.
The cost shows up if the trade goes against you. The short option’s strike becomes a level you must defend or accept being assigned.
Bullish Risk Reversal vs Bearish Risk Reversal
Same structure, opposite direction.
When and Why Traders Use Each Direction
The bullish risk reversal suits a trader who is moderately bullish on BTC, willing to buy BTC at a lower strike if the market dips, and wants leveraged upside if BTC rallies.
The bearish risk reversal suits a trader who is bearish on BTC, willing to sell BTC at a higher strike if the market rallies, and wants leveraged downside if BTC falls.
In both cases, the trade benefits if implied volatility favours one side of the strikes you are using.
Volatility Skew and Why It Makes Risk Reversals Attractive in Crypto
Crypto has a unique IV profile. OTM puts are usually more expensive than OTM calls of the same Delta. This is called “downside skew.”
Skew Explained: OTM Puts vs OTM Calls: Which Is More Expensive?
In a normal crypto market, traders are willing to pay more for downside protection (puts) than upside speculation (calls) at the same Delta. The result: implied volatility on a 0.30 Delta put is often higher than the IV on a 0.30 Delta call.
This skew creates a real edge for bullish risk reversals. You sell the expensive put and buy the cheaper call. The net credit (or near-zero cost) is favourable.
How to Use Skew to Enter Risk Reversals at a Credit
If skew is steep, a bullish risk reversal can sometimes be entered at a small net credit. You get paid to take the trade.
In ETH options, skew often runs even steeper than BTC, making bullish risk reversals on ETH a popular play among institutional desks.
For bearish risk reversals, skew works against you. You sell the cheaper call and buy the more expensive put, so the trade usually starts at a debit.

Strike Selection and Expiry Choice
For a bullish risk reversal on BTC at ₹65,00,000:
- Sell a one-month 0.20 Delta put, say at the ₹61,00,000 strike, for ₹35,000.
- Buy a one-month 0.20 Delta call, say at the ₹69,00,000 strike, for ₹30,000.
Net credit: ₹5,000. You receive a small credit just to enter the trade.
For a bearish risk reversal, reverse the strikes:
- Sell a one-month 0.20 Delta call at ₹69,00,000 for ₹30,000.
- Buy a one-month 0.20 Delta put at ₹61,00,000 for ₹35,000.
Net debit: ₹5,000. You pay a small amount to enter.
Strike choice depends on how aggressive you want the trade. Closer strikes (higher Delta) generate more premium and more exposure. Farther strikes (lower Delta) cost less and have less impact.
Net Premium Calculation (Debit or Credit Trade?)
Whether the trade is net debit or credit depends on three things: which direction you take, how steep the skew is, and which strikes you choose.
The CoinSwitch Pro Strategy Builder calculates this automatically when you assemble both legs. You can see net debit/credit, max profit, max loss, breakeven, and net Greeks before submitting.
Risk Reversal vs Buying a Call/Put Outright: Comparison
| Feature | Long Call | Bullish Risk Reversal |
|---|---|---|
| Cost | Full premium | Near zero or small credit |
| Upside | Unlimited | Unlimited |
| Downside | Limited to premium | Unlimited below short put strike |
| Best when | Cheap IV, big move expected | Bullish view, willing to own BTC at lower strike |
A long call caps your loss but costs more. A bullish risk reversal lowers the upfront cost but adds downside risk. The choice depends on whether you want defined or undefined risk.
For bearish: long put vs bearish risk reversal works the same way in reverse.
Managing and Exiting a Risk Reversal Position
The trade is not set and forget.
If BTC moves in your favour, the long option gains value and the short option loses value (in your favour). You can close both legs together for a profit.
If BTC moves against you toward the short strike, you face two choices. Close the trade at a loss before assignment, or accept being assigned (you buy BTC at the put strike for a bullish risk reversal, or sell BTC at the call strike for a bearish one).
A key rule: never let a short option leg drift into deep ITM territory without a plan. Either close it, roll it, or accept the assignment.
Key Takeaways
The risk reversal is an elegant way to express a directional view in crypto options at low cost. Bullish risk reversals (short put, long call) work best because crypto’s natural downside skew makes them attractive. Bearish risk reversals are workable but typically cost more to enter.
Use them when you have a strong directional view, are comfortable with the obligation on the short leg, and want better capital efficiency than a single long option.
CoinSwitch Pro’s Strategy Builder handles the two-leg execution cleanly. Watch your net Delta, manage breaches with discipline, and never let a short option go unmanaged into expiry.
FAQs
Q: Is a risk reversal the same as a synthetic future? Close but not identical. A synthetic long future uses ATM strikes (sell ATM put, buy ATM call). A risk reversal uses OTM strikes, which creates a flat zone in the middle where neither leg has intrinsic value.
Q: Can I lose more than I make on a risk reversal? Yes. The short option leg has potentially large downside (for a short put) or upside (for a short call) risk. The long option only partially hedges that risk.
Q: What is the best Delta for risk reversal strikes? 0.15 to 0.25 Delta is a common range. Lower Delta strikes are more conservative. Higher Delta strikes give more exposure but more risk.
Q: Why does crypto have a downside skew? Traders are willing to pay more for downside protection in volatile assets like BTC and ETH. This is consistent across most crypto markets and even applies to many equity indices.
Q: How is a risk reversal taxed in India? Each leg is a separate taxable event. The 30% flat VDA tax applies if classified as VDA income, with 1% TDS on gross proceeds per leg.
Q: When should I close a risk reversal early? If your long leg gains 50% or more, consider closing the trade. If the short leg drifts toward ITM, close or roll well before expiry.
