Naked Put Strategy Australia: Risks, Rewards & 2025 Updates

Australian investors are always on the lookout for new strategies to boost returns, and in 2025, ‘naked puts’ have emerged as a hot topic among options traders. But what exactly is a naked put, how does it work, and what are the new risks and rules you need to know? Let’s break down the essentials and see how this high-stakes play fits into the modern Aussie investing landscape.

What Is a Naked Put?

A naked put—sometimes called an uncovered put—is an options trading strategy where you sell (or ‘write’) a put option on a stock you don’t own. You pocket the premium upfront, but you’re exposed to the risk of being forced to buy the underlying shares at the strike price if the stock drops below that level.

For example, if you sell a naked put on BHP Group at a strike price of $40, and the share price falls to $35 before expiry, you may be obligated to buy BHP at $40—even though it’s trading much lower. Your profit is limited to the premium collected, but your loss can be substantial if the stock plunges.

• Income Generation: You collect an upfront premium from the buyer.
• Obligation: If the stock falls, you must buy at the agreed price.
• Uncapped Risk: Losses can mount if the stock price tanks.

Who Uses Naked Puts—and Why?

This strategy is not for the faint-hearted. Naked puts are generally used by experienced investors who are either:

• Looking to generate extra income in a flat or rising market
• Happy to own the underlying shares at a lower price
• Confident in their market outlook and risk management skills

For instance, a seasoned investor might sell naked puts on blue-chip ASX stocks they’re willing to buy anyway, hoping to acquire them at a discount or simply pocket the premium if the share price stays above the strike price. In 2025, with volatility picking up in mining and tech stocks, some traders have used naked puts to take advantage of rich option premiums—but not without risk.

2025: Regulatory Updates and Market Trends

Australian regulators have stepped up scrutiny of high-risk options strategies, especially after increased retail participation in 2024. The ASX and ASIC now require stricter margin requirements for selling naked puts, reflecting the potential for outsized losses. Key changes for 2025 include:

• Higher Minimum Margins: Brokers may require up to 50% of the contract value as collateral for naked put positions.
• Suitability Assessments: Investors must pass updated knowledge checks and risk assessments before being approved for naked put trading.
• Mandatory Disclosures: Enhanced risk warnings are now standard when placing uncovered options trades.

These shifts aim to protect investors from misjudging their risk exposure, especially as AI-driven volatility and global macro events shake local markets. For example, in early 2025, a sharp correction in lithium stocks caught some traders off guard, highlighting the dangers of being overexposed to naked puts without adequate margin or a fallback plan.

Managing the Risks: Real-World Considerations

If you’re considering naked puts, risk management is everything. Here’s what savvy investors are doing in 2025:

• Only selling puts on stocks they want to own—so assignment isn’t a disaster.
• Using stop-loss orders or rolling positions to cap downside if the market turns.
• Keeping cash reserves to meet margin calls and avoid forced selling in a downturn.
• Staying informed about company news and sector trends—because a profit warning or regulatory change can send stocks tumbling.

As always, position sizing is crucial: experienced traders rarely risk more than a small percentage of their portfolio on naked puts, given the possibility of large, sudden losses.

Conclusion

Naked puts can be a powerful tool for generating income or acquiring shares at a discount, but they come with real risks—especially in an unpredictable 2025 market. With tighter regulations and more volatility, it’s more important than ever to know exactly what you’re getting into, have a clear plan, and only use naked puts as part of a well-diversified strategy.
