Bank Nifty level used in this article: Rs 57,762 (as of 21 Aug 2026). Next monthly (last Tuesday of the month) expiry: 25 August 2026 (Tuesday). Lot size 30. Weekly options on Bank Nifty were discontinued in November 2024 under SEBI’s one weekly index per exchange rule; only monthly contracts remain.
Quick Answer
The guts strategy Bank Nifty sells an in the money call and an in the money put, both on the same expiry, at strikes on opposite sides of the current index level. With Bank Nifty at Rs 57,762, the short guts strategy Bank Nifty collects a substantial net credit upfront because both options carry intrinsic value in addition to time value, but it carries unlimited risk on both sides, similar to a short strangle, and requires the index to move enough for the combined intrinsic value to be overcome before expiry for the position to reach a loss. The guts strategy Bank Nifty is less commonly used than the short strangle for premium collection because of the larger capital and margin typically required.
The this strategy is essentially a strangle built with in the money strikes instead of out of the money strikes. Selling in the money options generates a much larger credit upfront, since the premium includes substantial intrinsic value on both legs, not just time value. This larger credit provides a wider cushion before the position moves into a loss compared with a standard short strangle built from out of the money strikes.
Because of the large notional value tied up in in the money options, the guts strategy Bank Nifty typically requires more margin than an equivalent short strangle, and the mechanics of managing two in the money legs simultaneously add a layer of complexity not present in out of the money strategies.

What Is the The position?
The guts strategy Bank Nifty is a two leg options trade that sells an in the money call and an in the money put, with strikes positioned on opposite sides of the current index level, both on the same expiry. The net credit collected is substantial due to the intrinsic value in both legs, and this credit is also the maximum profit.
The two legs of the this trade are:
- Sell an in the money call at a strike below the current index level, which carries intrinsic value from the outset
- Sell an in the money put at a strike above the current index level, which also carries intrinsic value from the outset
Because both legs are already in the money, the combined premium collected is considerably larger than a comparable out of the money short strangle, but the position still carries unlimited theoretical risk beyond the breakeven points on either side, since there are no protective long options.
How Does the Guts Strategy Bank Nifty Work?
With Bank Nifty at Rs 57,762, the this options approach might sell a call near 57,450, which is below the current level and therefore in the money, and a put near 58,150, which is above the current level and also in the money. The wide breakevens created by the large credit collected are the defining characteristic of the guts strategy Bank Nifty.

The spread: Step by Step Setup
- Identify strikes on opposite sides of the current level. With Bank Nifty at Rs 57,762, the guts strategy Bank Nifty requires selecting an in the money call strike below the current level and an in the money put strike above it.
- Assess the combined credit relative to the width between strikes. The larger the credit relative to the distance between the two strikes, the wider the effective breakeven range for the this strategy.
- Sell the ITM call and ITM put simultaneously. Both legs of the guts strategy Bank Nifty should be placed at the same time to avoid legging risk given the large notional values involved.
- Calculate both breakeven points. Upper breakeven equals the put strike plus the net credit. Lower breakeven equals the call strike minus the net credit, for the the position.
- Confirm margin requirements before entry. Because both legs are in the money, the guts strategy Bank Nifty typically requires more margin than a comparable out of the money short strangle; verify this on your broker’s margin calculator.
Illustrative Payoff: This trade
Illustrative example for educational purposes only. The guts strategy Bank Nifty carries unlimited theoretical loss potential on the upside. Strikes and premiums are hypothetical and should not be interpreted as a trade recommendation.
Hypothetical setup: Sell 57,450 CE (in the money) at Rs 310 per unit. Sell 58,150 PE (in the money) at Rs 295 per unit. Net credit: Rs 605 per unit. Lot size: 30 units.
| Bank Nifty at Expiry | P&L Per Lot (approx, Rs) | Outcome |
|---|---|---|
| Far below 56,845 | Large loss, growing | Call intrinsic value loss accelerates below the lower breakeven |
| 56,845 (lower breakeven, approx) | 0 | Breakeven |
| Between the two strikes | +18,150 (max profit, illustrative) | Both legs settle near their intrinsic value; net credit largely retained |
| 58,755 (upper breakeven, approx) | 0 | Breakeven |
| Far above 58,755 | Large loss, growing without cap | Put intrinsic value loss accelerates above the upper breakeven |
The this options approach illustrates a wide profit zone funded by a large upfront credit, but the underlying risk beyond the breakevens remains unlimited, the same structural risk as a short strangle, just built with in the money rather than out of the money strikes.
Greeks for the Guts Strategy Bank Nifty
Delta: The guts strategy Bank Nifty starts closer to delta neutral when the two strikes are roughly symmetric around the current index level, though each leg individually carries a larger delta than a comparable out of the money strangle leg due to being in the money.
Gamma: The guts strategy Bank Nifty is short gamma, similar to a short strangle, with the effect concentrated as the index approaches either strike near expiry.
Theta: Theta decay benefits the guts strategy Bank Nifty, though a larger portion of the option’s value is intrinsic rather than time value compared with an out of the money strangle, so the daily time decay captured is proportionally smaller relative to the total premium collected.
Vega: The guts strategy Bank Nifty is short vega. A rise in implied volatility after entry generally increases the cost of buying back the position.
When the Guts Strategy Bank Nifty May Be Considered
The guts strategy Bank Nifty may be considered when a trader wants a wider effective breakeven range than a standard short strangle and is willing to commit the additional margin required; when in the money options are relatively liquid for the chosen index; or as an alternative structure for expressing a neutral view with more cushion before losses begin.
When NOT to Use the Guts Strategy Bank Nifty
Consider avoiding the guts strategy Bank Nifty when margin capital is limited, since it typically requires more than a comparable short strangle; when in the money option liquidity is poor for the chosen index, leading to wider bid ask spreads on large notional positions; or when a major event could move the index sharply, given the unlimited risk profile.
Risk Management
The unlimited risk profile of the guts strategy Bank Nifty requires the same disciplined approach as a short strangle: a pre defined exit rule based on a multiple of the credit received, a specific index level, or a time based rule ahead of expiry when gamma risk increases. Given the larger notional value involved, position sizing for the guts strategy Bank Nifty should account for the increased margin and capital commitment.
Transaction Costs
The guts strategy Bank Nifty involves two option legs with substantial notional value due to their in the money status. Brokerage, exchange transaction charges, STT, GST, SEBI charges, stamp duty, and bid ask spread impact can be more significant in absolute terms than for a comparable out of the money short strangle, given the larger premiums involved.
