What Is a Cash-Secured Put? Strategy, Risk and NIFTY Example
Learn how a cash-secured put works, its premium, breakeven, downside risk and how it differs from an unhedged short put.
What Is a Cash-Secured Put?
A Cash-Secured Put is a strategy in which a trader sells a put while keeping sufficient capital available for the intended obligation.
The strategy is often associated with a willingness to acquire the underlying at the chosen strike.
For index options such as NIFTY, settlement mechanics are different from physically delivered stock options because the index itself cannot be delivered.
NIFTY Example
Suppose NIFTY is near 25,000.
A trader sells a 24,500 Put for an illustrative premium of 100 points.
The trader receives:
100 points of premium
If NIFTY expires above 24,500, the put expires out of the money and the premium is retained, before costs.
Expiry Payoff
For a short put:
P&L = Premium Received − Max(Strike − Spot, 0)
Using:
If NIFTY expires at 24,000:
Intrinsic value = 500
P&L:
100 − 500 = −400 points
Breakeven
Breakeven = Strike − Premium
Therefore:
24,500 − 100 = 24,400
Below 24,400, the short put loses money at expiry.
Maximum Profit
Maximum profit is limited to the premium received.
Here:
100 points
Downside Risk
A short put can experience substantial losses if the underlying falls significantly.
For stock options, assignment can result in acquiring shares at the strike under the relevant contract terms.
For NIFTY index options, settlement is cash-based, so the mechanics are different.
Cash-Secured Put vs Naked Put
The short option can be the same, but the capital arrangement differs.
A cash-secured approach keeps sufficient capital available for the intended obligation.
An insufficiently funded or naked short put can have a different margin and risk-management profile.
NIFTY Payoff Table
| NIFTY at Expiry | Intrinsic Value | P&L |
|---:|---:|---:|
| 25,200 | 0 | +100 |
| 25,000 | 0 | +100 |
| 24,500 | 0 | +100 |
| 24,400 | 100 | 0 |
| 24,000 | 500 | -400 |
This illustrates how premium provides a buffer but does not eliminate downside risk.
Implied Volatility
Higher IV can increase option premiums, but it also reflects greater uncertainty in option pricing.
A higher premium should not be treated as risk-free income.

Delta
Delta measures option-price sensitivity and is sometimes used as a rough probability proxy.
It should not be treated as a guaranteed probability of assignment or profit.

Final Thoughts
A Cash-Secured Put is not simply a premium-income trade.
It is fundamentally a short-put risk profile backed by capital.
The important numbers are the strike, premium, breakeven and downside exposure.
Frequently Asked Questions
Is a cash-secured put risk-free?
No.
Is the premium guaranteed profit?
No. The overall position can lose money if the underlying falls sufficiently.
Can it be used on NIFTY?
Yes, but NIFTY index options have cash-settlement mechanics rather than physical delivery.
