Bankex level used in this article: Rs 59,500 (as of illustrative reference level; verify current level on BSE). Next monthly (last Thursday of the month) expiry: 27 August 2026 (Thursday). Lot size 15. Weekly options on Bankex were discontinued in November 2024 under SEBI’s one weekly index per exchange rule; only monthly contracts remain.
Quick Answer
The collar strategy Bankex combines a long Bankex futures or equivalent position with a protective put purchase and a covered call sale, creating a rangebound payoff that limits both downside loss and upside gain. With Bankex at Rs 59,500, the collar strategy Bankex may be considered by traders who already hold a bullish Bankex futures position and want to reduce downside risk, typically at little to no net cost since the premium from the sold call can offset the cost of the purchased put. Because Bankex only trades monthly options, the collar strategy Bankex is generally structured around the monthly expiry cycle.
Unlike the other strategies in this series, the this strategy is built around an existing directional position rather than being a standalone options trade. It is most commonly used by traders or investors who hold Bankex futures and want to define a floor and a ceiling on their potential outcome over the monthly cycle, in exchange for giving up unlimited upside.
The collar strategy Bankex is sometimes structured as a zero cost collar, where the premium received from selling the call closely offsets the premium paid for the put. This is not guaranteed and depends on the specific strikes chosen relative to the current index level and the prevailing implied volatility skew.

What Is the The position?
The collar strategy Bankex involves three components: an existing long position in Bankex futures (or a proxy long exposure), the purchase of a protective out of the money put, and the sale of a covered out of the money call. Together these create a defined range for the combined position’s outcome over the monthly cycle.
The two options legs of the this trade are:
- Buy an out of the money put below the current index level, which protects against a decline beyond the put strike
- Sell an out of the money call above the current index level, which caps the upside gain beyond the call strike and helps fund the cost of the put
Both options legs of the collar strategy Bankex share the same monthly expiry as each other, though they need not match the futures contract’s own expiry precisely. The net cost of the options legs (put premium paid minus call premium received) is added to or subtracted from the futures position’s cost basis.
How Does the This options approach Work?
With Bankex at Rs 59,500, a trader holding a long Bankex futures position might buy a put at 59,150 and sell a call at 59,850 for the collar strategy Bankex, both on the next monthly expiry. This defines a floor near 59,150 and a ceiling near 59,850 for the combined position’s outcome, regardless of how far the index moves beyond either level.
| Parameter | Details |
|---|---|
| Index | BSE Bankex (BSE) |
| Expiry | Monthly only, last Thursday of the month. Effective September 2025 (NSE and BSE index expiry swap). Weekly contracts discontinued November 2024. |
| Lot Size | 15 units (effective from January 2026 per NSE circular, reduced from 20) |
| Strategy Type | Protective, requires existing long futures exposure |
| Legs | 1 long put plus 1 short call (in addition to the underlying futures position) |
| Max Profit | Capped at the short call strike minus the futures entry price and net options cost, times lot size |
| Max Loss | Capped at the futures entry price minus the long put strike plus net options cost, times lot size |
| Margin | Varies dynamically. Check live margin on your broker’s calculator before placing any order. |
The spread: Step by Step Setup
- Start with an existing long Bankex futures position. The collar strategy Bankex is a protective overlay, not a standalone directional bet, so it assumes you already hold or intend to hold the underlying exposure.
- Select the protective put strike. With Bankex at Rs 59,500, a put strike below the current level, such as 59,150, defines the floor for the this strategy. A strike closer to the current level costs more but offers tighter protection.
- Select the covered call strike. A call strike above the current level, such as 59,850, defines the ceiling. Selling a call closer to the current level generates more premium but caps the upside sooner.
- Compare the put cost and call credit. If the call premium received roughly offsets the put premium paid, the collar strategy Bankex approaches zero net cost on the options legs, though this depends on the specific strikes and market skew at the time.
- Monitor the position through the monthly expiry. Decide in advance whether to let the options expire, close them early, or roll the the position into the next monthly cycle if you intend to maintain the hedge.
Illustrative Payoff: Collar Strategy Bankex
Illustrative example for educational purposes only. Strikes, premiums and calculations are hypothetical and should not be interpreted as a trade recommendation.
Hypothetical setup: Long Bankex futures at Rs 59,500. Buy 59,150 PE. Sell 59,850 CE. Assume the options legs are close to zero net cost. Lot size: 15 units.
| Bankex at Monthly Expiry | Combined P&L Per Unit (approx, Rs) | Combined P&L Per Lot (15 units, Rs) | Outcome |
|---|---|---|---|
| Below 59,150 | -350 | -5,250 | Loss capped by protective put |
| 59,500 (unchanged) | 0 (approx) | 0 (approx) | Near breakeven on futures leg |
| 59,850 and above | 350 | 5,250 | Gain capped by covered call |
The collar strategy Bankex caps both the downside loss and the upside gain of the combined futures plus options position. Between the two strikes, the outcome broadly tracks the futures position’s own P&L, adjusted for any net options cost or credit.
Greeks for the Collar Strategy Bankex
Delta: The collar strategy Bankex retains a positive delta from the underlying long futures position, partially offset by the short call and partially reinforced by the long put once the index approaches either strike.
Gamma: The options legs of the collar strategy Bankex introduce gamma exposure near each strike, most relevant close to the monthly expiry.
Theta: The net theta of the collar strategy Bankex depends on the relative size of the put and call premiums; if structured near zero cost, the theta impact of the two options legs tends to partially offset each other.
Vega: The collar strategy Bankex has modest net vega exposure since the long put and short call carry opposing vega, though the exact balance depends on the specific strikes chosen.
When the Collar Strategy Bankex May Be Considered
The collar strategy Bankex may be considered when you hold an existing long Bankex futures position and want to protect against a significant decline while being willing to give up some upside potential; ahead of an event with uncertain outcome where you want to remain invested but limit the downside; or as a lower cost alternative to buying a standalone protective put.
When NOT to Use the Collar Strategy Bankex
Consider avoiding the collar strategy Bankex when you do not hold or intend to hold the underlying futures position, since the collar is a hedge rather than a standalone directional trade; you have strong conviction in a large rally, since the covered call would cap those gains; or the strikes available do not offer an attractive cost structure relative to the protection provided.
Risk Management
The collar strategy Bankex is itself a risk management tool, but the trader should still monitor both option legs through the monthly expiry, decide in advance whether to roll the collar into the next cycle, and reassess the strikes if the underlying futures position is adjusted.
Transaction Costs
The collar strategy Bankex involves three positions (futures, long put, short call), each with its own transaction costs. Brokerage, exchange transaction charges, STT, GST, SEBI charges, and stamp duty apply to the futures leg as well as both options legs, and should be weighed against the cost savings versus a standalone protective put.

Collar vs Other Bankex Protective Strategies
| Strategy | Requires Existing Position | Downside Protection | Upside Participation | Net Cost |
|---|---|---|---|---|
| Collar | Yes (long futures) | Capped at put strike | Capped at call strike | Low, often near zero |
| Protective Put | Yes (long futures) | Capped at put strike | Unlimited | Full put premium |
| Covered Call | Yes (long futures) | None beyond call premium received | Capped at call strike | Negative (credit received) |
The collar strategy Bankex sits between a standalone protective put, which preserves unlimited upside at a higher cost, and a covered call alone, which generates income but offers no downside protection beyond the premium collected.

Conclusion
The collar strategy Bankex is a protective structure for traders who already hold Bankex futures exposure and want to define a floor and ceiling on their outcome over the monthly options cycle. It is not a standalone directional trade, and its value depends on already having the underlying position to hedge. Always verify current lot size (15 units from January 2026) and the monthly expiry schedule on NSE before executing any trade.
