Home Country Bias: Why Australian Investors Need to Diversify in 2025

Do you know how much of your portfolio is tied up in Aussie shares? If the answer is “almost all of it,” you’re not alone. But in 2025, home country bias could be limiting your wealth building more than ever.

What is Home Country Bias?

Home country bias is the tendency for investors to allocate a disproportionate share of their investments to domestic assets, such as Australian shares, property, or bonds. It’s a global phenomenon, but it’s especially pronounced here in Australia, where local equities often feel familiar and less risky.

According to Vanguard’s 2025 Global Investor Study, Australians on average hold over 65% of their equity investments in ASX-listed companies, despite Australia making up less than 2% of the world’s share market by value. That’s a big bet on one relatively small corner of the global economy.

Why Do Australians Favour Local Assets?

• Familiarity: We tend to trust companies we know, like the big four banks or major miners.

• Franking credits: Australia’s dividend imputation system makes local shares tax-effective, especially for retirees.

• Perceived safety: There’s a comfort in investing close to home, with local news and regulations.

• Currency concerns: Some fear that investing overseas exposes them to currency swings and complexity.

But this comfort comes at a cost. Australian shares are heavily concentrated in financials and resources, and our market is far less diversified than the global average. If local sectors stumble, so could your portfolio.

The Risks of Home Country Bias in 2025

The global investment landscape is shifting rapidly. In 2025, several factors are making home country bias riskier than ever:

• Market concentration: Over 50% of the ASX200’s value sits in just two sectors: financials and materials. If banks or miners face headwinds, so does your portfolio.

• Slower economic growth: The Reserve Bank of Australia (RBA) forecasts modest GDP growth of 2.1% for 2025, lagging behind the US and parts of Asia.

• Global innovation elsewhere: The world’s leading tech, healthcare, and green energy companies are mostly listed offshore. By staying local, investors miss out on the world’s growth engines.

• Currency risk cuts both ways: While the AUD can be volatile, global diversification can actually reduce your overall risk profile, especially if the Australian dollar weakens.

Real-world example: In 2024, the S&P/ASX 200 returned just 6.2%, while the MSCI World ex-Australia Index delivered over 18% in AUD terms, thanks to strong US and European performance. Investors with global exposure reaped the benefits.

How to Diversify Beyond Australia in 2025

The good news? Diversifying globally is easier and more cost-effective than ever. Here’s how Australians are overcoming home country bias in 2025:

• Global ETFs: Low-cost exchange-traded funds tracking the S&P 500, MSCI World, or emerging markets can provide instant international exposure.

• Managed funds: Many actively managed funds offer global or regional diversification, with professional oversight.

• Direct shares: Platforms now allow Australians to buy US, UK, and Asian shares directly, often with fractional investing and lower brokerage fees.

• Superannuation: Review your super fund’s investment mix. Many default options are still heavily weighted to Australian assets; consider switching to an option with more global diversification.

Remember, the right mix depends on your risk tolerance, investment goals, and time horizon. But even a modest allocation to global assets can dramatically reduce portfolio risk and open up new opportunities.

Breaking the Bias: Tips for 2025

• Review your portfolio’s geographic allocation at least annually.

• Don’t chase last year’s winners—focus on long-term, structural trends.

• Use technology: Portfolio tracking apps now make it easy to see your real exposure, sector by sector, country by country.

• Stay informed about global economic shifts, not just local headlines.

Conclusion

Home country bias is understandable, but in a world where opportunities are increasingly global, it’s a risk Australians can’t afford to ignore. By broadening your horizons in 2025, you’ll build a more resilient, growth-oriented portfolio—without leaving your comfort zone too far behind.
