Maximum Drawdown (MDD) Explained: 2025 Guide for Australian Investors

Maximum Drawdown (MDD) isn’t just another bit of financial jargon—it’s a powerful measure of risk that every Australian investor should be tracking in 2025. As markets face ongoing volatility and regulatory shifts, understanding MDD can mean the difference between weathering a financial storm and sinking with the ship.

What Is Maximum Drawdown (MDD)?

Maximum Drawdown (MDD) is the largest single drop from peak to trough in the value of an investment portfolio, before a new peak is achieved. Put simply, it’s the worst-case loss scenario an investor might experience in a given time frame, without cashing out. Unlike simple loss percentages, MDD focuses on the most severe sustained loss, offering real insight into downside risk.

• Example: If your portfolio hits a high of $100,000 and then drops to $75,000 before recovering, your MDD is 25%.

• Relevance: MDD helps you understand the resilience of your investments during turbulent periods.

Why MDD Matters More in 2025

With global markets in flux and ongoing aftershocks from inflation, interest rate hikes, and geopolitical uncertainty, Australians are more exposed to sharp market swings than ever before. In 2025, regulators like ASIC are pushing for better risk disclosure and stress-testing, making MDD an even more essential tool for both professional and retail investors.

• Superannuation Funds: The Your Future, Your Super reforms have put pressure on funds to improve transparency around performance and risk. Many super funds now report their MDD figures alongside returns, helping members make informed choices.

• Managed Funds & ETFs: Platforms like ASX and Morningstar have begun highlighting MDD in their fund analysis tools, recognising its growing importance to retail investors.

• Policy Update: In 2025, APRA’s updated Prudential Standard SPS 530 requires superannuation trustees to include drawdown scenarios in their stress-testing frameworks, directly referencing MDD as a key metric.

How to Use MDD to Strengthen Your Portfolio

Understanding MDD can empower you to build a portfolio that matches your risk tolerance and investment horizon. Here’s how Australians are putting MDD to work in 2025:

• Comparing Investments: Don’t just chase high returns—compare MDD figures between similar funds or ETFs. A fund with slightly lower returns but a much smaller MDD may offer a smoother ride in turbulent times.

• Stress-Testing Your Holdings: Use MDD as a gut-check: Would you stay invested if your portfolio lost 20%? 30%? Knowing your psychological limits helps you avoid panic selling during downturns.

• Blending Assets: Diversifying with assets that have low correlation and different MDD profiles—like combining equities with bonds, infrastructure, or even gold—can help reduce overall portfolio drawdown.

Example: In 2022–2023, many Australian balanced super funds saw MDDs of 8–12% during market corrections, while high-growth funds experienced drawdowns as steep as 20%. Investors who understood these risks were better prepared to ride out the volatility.

Beyond the Numbers: The Human Side of MDD

MDD isn’t just about statistics—it’s about investor behaviour. Research shows that investors often sell at the bottom when fear peaks. By understanding and planning for MDD, you can build emotional resilience and stick to your long-term strategy, instead of reacting impulsively to market noise.

• Set realistic expectations for temporary losses.

• Review your financial goals and time horizon annually.

• Discuss MDD and risk tolerance with your adviser or family to ensure everyone’s on the same page.

Conclusion: Make MDD Your Secret Weapon in 2025

Maximum Drawdown is more than a backward-looking statistic—it’s a forward-looking risk management tool. In a world where market shocks are the new normal, tracking and understanding MDD can help you build a portfolio that’s not just profitable, but resilient. As you review your investment strategy in 2025, make MDD a core part of your decision-making process—and turn market volatility into an opportunity, not a threat.
