Super Fund Returns Hit Hard in March 2026: Why Switching to Cash Could Be the Worst Move You Make

Your Super Statement Just Got Uglier. Don’t Panic.

If you have logged into your superannuation account recently, you have probably noticed the damage. After three consecutive years of strong returns, March 2026 has delivered a sharp reminder that markets do not move in one direction.

Chant West, one of Australia’s leading superannuation research houses, estimates the median growth super fund has lost approximately 3.8% in March alone (as at 23 March 2026). That single month has wiped out most of the gains accumulated since the start of the financial year, dragging the 2025-26 financial-year-to-date return down to around 2.5%.

For a member with a $400,000 super balance in a growth option, that March decline translates to roughly $15,200 in paper losses in less than four weeks.

The temptation to do something, anything, is strong. Switch to cash. Move to conservative. Lock in what is left.

But the evidence is overwhelming: that is almost certainly the worst thing you can do.

What Happened to Markets in March 2026

The Trigger: Middle East Conflict Escalation

On 28 February 2026, the United States and Israel launched strikes against Iranian military targets. Iran’s response, including disruption to shipping in the Strait of Hormuz, sent oil prices surging above US$102 per barrel (Brent crude) and triggered a global risk-off event in equity markets.

The ASX 200 has fallen approximately 9% from its February highs, hitting 10-month lows on 23 March. The sell-off has been broad-based, hitting technology stocks, consumer discretionary, and financial services particularly hard. Energy and gold stocks have been the notable exceptions, benefiting from rising oil and gold prices.

The Flow-On Effects

The oil price shock has had cascading effects on the Australian economy and markets:

For super funds, the ASX decline is the primary driver of losses, since the median growth fund holds 50-65% in equities (both Australian and international). International shares have also fallen, and the decline in the Australian dollar has only partially offset losses on overseas holdings.

How Different Super Options Have Performed

Not all super fund options have been hit equally. Here is how the major investment categories have fared in March 2026 (estimates based on Chant West data and index movements to 23 March):

The irony is that cash, the option panicking members are tempted to switch into, has the highest financial-year-to-date return. But that is because cash benefited from high interest rates throughout the year while avoiding the March equity decline entirely. The question is not which option performed best over the last four weeks. It is which option will perform best over the next 10, 20, or 30 years.

Why Switching to Cash During a Sell-Off Almost Always Backfires

The Mathematics of Missing the Rebound

Market recoveries tend to be concentrated in a small number of trading days, and those days often come when sentiment is at its worst. Research from Vanguard Australia shows that missing just the 10 best trading days on the ASX over a 20-year period can reduce your total return by more than half.

Here is a simplified example using a $400,000 super balance:

The member who panics, switches to cash for six months, and then switches back gives up an estimated $203,000 over 20 years. The member who stays in cash permanently retires with less than half the wealth of the member who stayed the course.

These are not hypothetical numbers. They reflect the real cost of trying to time the market with your retirement savings.

The Track Record: Growth Funds Over 30 Years

The median growth super fund has delivered positive returns in approximately 25 of the last 30 financial years. That means negative years happen roughly one year in six. The average annual return over that period is approximately 7.5% after fees.

Here are the worst calendar-year returns for the median growth fund over the past two decades:

Even after the worst financial crisis in living memory (the GFC), growth funds recovered and went on to deliver exceptional returns over the following decade. Members who switched to cash during the GFC and stayed there missed the recovery entirely.

What Chant West Says

Mano Mohankumar, head of superannuation investment research at Chant West, has been direct in his advice to members during the March sell-off:

“It’s critical for members to keep in mind that super is a long-term investment and there will inevitably be periods of market weakness through their super journey.”

He warned specifically against switching during downturns: “Far more often than not, that approach results in poorer long-term outcomes than if they stay the course. Not only do they crystallise their losses, but also risk missing part or all of the subsequent market rebound.”

What You Should Actually Do

If You Are Under 45: Do Nothing

If retirement is 20 or more years away, a month like March 2026 is noise in the context of your super journey. Your growth option will experience several more months like this before you retire. The long-term return differential between growth and conservative options is so large that staying invested through downturns is one of the most important decisions you can make for your retirement.

In fact, if you are making regular super contributions (as most employed Australians are through the Superannuation Guarantee), a market downturn is actually beneficial. Your fortnightly contributions are buying units at lower prices, which means you accumulate more units during the downturn. When the market recovers, those cheaper units appreciate in value. This is known as dollar-cost averaging, and it works powerfully in your favour during volatility.

If You Are 45 to 55: Review, Don’t React

This is the stage where many members start thinking about their risk tolerance. A review of your investment option is perfectly sensible at this age, but it should be driven by your overall retirement plan, not by last week’s headlines.

Consider whether your current option matches your time horizon. If you plan to retire at 67, you still have 12-22 years of investment ahead of you, which is plenty of time to ride out market cycles.

If you find that your risk tolerance genuinely does not match your current option (meaning you cannot sleep at night during sell-offs), then a considered, planned shift towards a balanced or growth-balanced option is reasonable. But do it as a strategic decision, not a reactive one.

If You Are Over 55: Think About Your Actual Time Horizon

Many people assume their investment horizon ends at retirement. It does not. Most Australians do not withdraw their entire super as a lump sum at age 67. Instead, they transfer it to an account-based pension and draw it down gradually over 20-30 years of retirement.

This means even at age 60, much of your super will remain invested for another two or three decades. A 100% conservative or cash allocation at this stage may feel safe, but it dramatically increases the risk that your savings will not last through retirement.

That said, if you are within five years of retirement and plan to make a large lump sum withdrawal (for example, to pay off a mortgage), it makes sense to hold that specific portion in a more defensive allocation. This is where professional financial advice becomes particularly valuable.

If You Have an SMSF: Review Your Investment Strategy

Self-managed super fund (SMSF) trustees have more control over their investment allocations but also more responsibility. If your SMSF is heavily concentrated in Australian equities, the March sell-off may have exposed a lack of diversification.

Now is a good time to review your SMSF investment strategy document and consider whether your actual asset allocation still aligns with the documented strategy. SMSF trustees are legally required to implement and regularly review their investment strategy under section 52B of the Superannuation Industry (Supervision) Act 1993.

Key questions for SMSF trustees:

• Is your portfolio adequately diversified across asset classes, sectors, and geographies?
• Do you have enough liquidity to meet pension payment obligations without being forced to sell assets at depressed prices?
• Have you considered defensive assets like bonds, term deposits, or gold as part of your allocation?
• Is your investment strategy document up to date and reflecting current market conditions?

The Bigger Picture: Super Fund Returns in Context

It is easy to fixate on short-term losses, but context matters. Here is how $100,000 invested in the median growth fund at various points in the past would have grown (after fees, before tax):

Every one of those starting points was followed by significant market turbulence. Every one still delivered substantially positive returns over the period. The message is consistent: time in the market beats timing the market.

Contribution Strategies During a Downturn

If you have the financial capacity, a market downturn is actually one of the best times to make additional super contributions. You are effectively buying assets at discounted prices.

Concessional (Before-Tax) Contributions

The concessional contribution cap for 2025-26 is $30,000 per year. This includes employer Superannuation Guarantee contributions, salary sacrifice contributions, and personal deductible contributions.

If your employer pays the minimum SG rate of 12% on a salary of $100,000, that is $12,000 in employer contributions, leaving you room to salary sacrifice up to $18,000 more before hitting the cap.

Concessional contributions are taxed at 15% within the fund (or 30% for individuals earning above $250,000), compared to your marginal tax rate outside super. For someone on a $120,000 salary (34.5% marginal rate including Medicare levy), each dollar contributed to super via salary sacrifice saves approximately 19.5 cents in tax.

Non-Concessional (After-Tax) Contributions

The non-concessional contribution cap for 2025-26 is $120,000 per year, or $360,000 using the bring-forward rule over three years (available if your total super balance is below $1.66 million).

Non-concessional contributions are not taxed when they enter the fund, and the investment earnings within super are taxed at a maximum of 15% (compared to your marginal rate outside super).

Carry-Forward Contributions

If your total super balance was below $500,000 on 30 June 2025, you can carry forward any unused concessional contribution cap amounts from the previous five financial years. This can allow significantly larger concessional contributions in a single year, which is particularly useful if you have had years of lower income or part-time work.

When to Seek Professional Advice

Chant West explicitly recommends that members considering switching options during volatile markets should see a financial adviser. This is sound advice.

A good financial adviser can help you:

• Assess whether your current super option matches your genuine risk tolerance and time horizon
• Model different scenarios for your retirement income
• Identify whether you should be making additional contributions
• Review insurance within super (which many members forget about)
• Develop a retirement income strategy for the transition from accumulation to pension phase
• Navigate SMSF-specific requirements if you are a trustee

The cost of professional advice is typically $2,000 to $5,000 for a comprehensive super review. Given that the difference between staying invested and panic-switching could be hundreds of thousands of dollars over a retirement lifetime, it is one of the best investments you can make.
