In every market crisis, investors are told that “this time is different”. In 2008 it was credit, in 2020 it was a virus, but in 2026, investors face a strange mix of high valuations, AI enthusiasm, geopolitical risk, and uncertainty over interest rates.

How much of your portfolio depends on one story being right?

Global diversification is a way of navigating not knowing which country, sector or asset class will lead next. A good portfolio does not need perfect predictions, just enough balance to survive bad ones.

The GFC: when “safe” assets were not so safe

The Global Financial Crisis began in the US housing market and spread through the banking system, becoming a worldwide crisis because banks, investors and financial products are all connected (RBA, 2026).

The GFC’s central lesson is that diversification can fail when everything is linked to the same hidden risk. Before the crisis, many mortgage backed securities looked diversified but the loans were exposed to the same broad forces of falling house prices, loose lending standards and too much debt. When they collapsed, the ‘diversification’ did too. This matters for global portfolio management because a portfolio can look diversified while still depending on one theme. An Australian investor may own five different funds and still be heavily exposed to the same banks, miners or large US technology companies.

The GFC also showed why liquidity matters. In a crisis, it can become difficult to exit seemingly stable positions at a fair price. The practical takeaway is to check whether different holdings share the same underlying risks and keep enough liquid assets to avoid forced selling at the worst moment.

COVID-19: when the market moved faster than the toilet paper

The COVID crash was different because it was sudden. In early 2020, markets had to price in a global health crisis, lockdowns, border closures, and a sharp hit to business activity almost simultaneously with a speed that shocked investors.

MSCI’s analysis found that global investing still offered diversification benefits during COVID because the pandemic affected regions at different times and with different intensities (MSCI, 2020). Travel, banks, energy and small businesses were hit hard, but technology and healthcare recovered faster.

The COVID period also showed that market timing is brutally difficult. Many investors sold out of fear but the recovery came quickly, investors who waited for market certainty missed the recovery. This shows that a plan needs to exist before the crisis. During panic, the brain wants certainty, which markets don’t provide. When the news is moving fast and the analysis can’t keep up, a plan made in advance is the only thing that holds.

The COVID lesson is that different parts of the world and different sectors recover at different speeds. A global portfolio spread across them has more paths back.

2026: the problem of crowded confidence

The uncertainty facing investors in 2026 is harder to read as investors are dealing with several pressures at once. 

Vanguard’s March 2026 Australian outlook shows that global and Australian equities have similar expected returns, but global equities have lower median volatility (Vanguard, 2026), suggesting that a global allocation can change the risk profile of an Australian portfolio.

BlackRock’s Q2 2026 outlook warns that portfolios may look diversified but often make large concentrated bets because a few major themes like artificial intelligence dominate markets (BlackRock, 2026). This means that buying a global fund is useful, but investors should check country exposure, sector exposure, currency exposure and the largest underlying holdings.

Listed investment companies are another way to get managed investment exposure; they trade on the ASX like shares, some invest locally and some globally. Morningstar’s 2026 LIC (Listed Investment Company) reporting tracks whether ASX listed LICs trade at a premium or discount to their net tangible assets (Morningstar, 2026), or, put simply, whether the share price is above or below what the LIC actually owns. A discount isn’t automatically a bargain, and a premium isn’t automatically a ripoff; investors need to assess the manager, fees, strategy and dividend policy and long term track record. ETFs, managed funds and LICs can all build global exposure, but the right structure depends on what the investor is trying to achieve.

What can we learn?

The GFC showed that hidden links can break a portfolio. COVID showed that speed matters and that recovery can arrive before confidence does. The 2026 environment shows that investors can be crowded into the same trades without realising it.

Each crisis has a different shape but the underlying problem was that the portfolio ‘looked diversified’ and wasn’t. In 2008, the one thing was house prices, in 2020 it was the pace of recovery; in 2026, it may be the assumption of the continued dominance of a small 

number of technology themes running through almost every major index in the world. An Australian investor who owns local shares, a global ETF and a few managed funds may feel diversified while sitting on a concentrated bet on AI and large cap US equities.

An Australian portfolio concentrated in local shares is already heavy on banks, resources and AUD exposure. Adding global diversification means different sectors, currencies and economic cycles, not just a global fund that holds the same major technology names as everything else in the portfolio. Investors who know exactly what they own are far better placed for when conditions change.

Building a portfolio for Australian investors may involve ETFs, managed funds, direct international shares or listed investment companies in Australia. The structure matters less than the discipline behind it.

The measure of a portfolio is how it performs during bad times, not when the market is good.
