Australia's economy has shown remarkable resilience, marking 17 consecutive quarters of growth by the end of 2025, with GDP expanding by 2.6% year-on-year. This growth has been driven by robust private investments, particularly in dwelling construction and data centres in New South Wales and Victoria. However, this economic expansion has not been without its challenges. Resurgent inflationary pressures have become a significant concern, fuelled by strong private sector demand and a tight labour market, with unemployment hovering around 4.2%. Additionally, the transition from coal to renewable energy has led to a surge in electricity costs, further contributing to structural inflationary pressures.

In response, the RBA has shifted from a cautious hold to active tightening, raising the cash rate by 25 basis points to 3.85% in February 2026, marking the first hike since November 2023. The escalation of geopolitical tensions, particularly the recent war in the Middle East, has exacerbated inflationary concerns, prompting the RBA to raise rates again in March to 4.1%. The central bank cited geopolitical risks and resultant inflationary pressures as key reasons for the rate hike.

Australia's geopolitical positioning adds another layer of complexity. While politically aligned with Western countries, Australia's economic fortunes are closely tied to trade partners in Asia, such as China, Japan, South Korea, and India. This dual alignment leaves Australia vulnerable to geopolitical shocks and economic uncertainties, particularly if tensions between the East and the West were to escalate.

In this context, Australian investors are urged to reconsider the relationship between bonds and equities. Inflationary concerns and potential further rate hikes are likely to push up local yields, adversely affecting both bonds and equities. "Our analysis shows that the correlation between bonds and equities rises alongside bond yields," noted Marissa Salim, Senior Research Lead at the World Gold Council. This could present significant challenges for investors seeking diversification.

Gold, however, offers a compelling alternative. Historically, gold has delivered positive returns across all RBA rate regimes since 2010, appreciating notably in Australian dollar terms since 2022. "Gold has maintained a consistently negative relationship with Australian equities over time, offering investors a reliable source of diversification and portfolio resilience," explained Ray Jia, Research Head APAC ex India at the World Gold Council.

The global nature of gold, driven by supply and demand dynamics and influenced by global geopolitical risks and major central banks' monetary policy paths, makes it largely independent of Australia's domestic monetary cycle. This independence underscores gold's role as a global asset, providing a hedge against both domestic and international uncertainties.

In recent years, gold has proven its worth as a portfolio risk diversifier. Since 2022, higher global inflation and frequent geopolitical shocks have driven bond–equity correlations higher. Yet, gold has consistently offered a negative correlation with Australian equities, providing a buffer during periods of market stress. "Gold has been put to the test during periods of systemic market stress and has proven to be the asset class that performed better than others during such periods," Jia highlighted.

The opportunity cost argument, often used against gold, has shifted in gold's favour since 2022. While cash deposits have yielded around 3%, and fixed income instruments have seen real returns fall, gold has appreciated significantly in AUD terms. This appreciation has more than offset the opportunity cost of holding a non-yielding asset, reinforcing gold's strategic value in investment portfolios.

In summary, the case for gold in Australian portfolios has only grown stronger amidst current economic and geopolitical uncertainties. As Salim aptly put it, "The question for Australian investors is no longer whether gold belongs in portfolios, but how can it not." Gold's role as a strategic asset remains highly relevant, offering both a hedge against macroeconomic uncertainties and a means of diversification in an increasingly complex global landscape.
