What do current geopolitical events tell us about investing?

The recent escalation in the Iran conflict-marked by direct US and Israeli strikes and retaliatory exchanges, together with threats to key shipping lanes, such as the Strait of Hormuz-has thrust geopolitics back into the spotlight.

Energy supply risks and regional instability have caused significant market volatility.

The reason this is a very significant global issue is because energy is a key input to all sectors across the economy, and no sector is immune from its effects.

For investors, this is a timely reminder that the key principles, like diversification and horizon-based planning, matter more when the geopolitics are consistently in the headlines.

And the good news? Staying disciplined can help mitigate uncertainty and protect holdings and potential allocations from significant downside risk.

Immediate market shocks take hold

Markets reacted swiftly. Oil prices spiked on fears of disrupted supply, pushing energy stocks higher while broader equity indices dipped amid inflation worries.

This comes at a time when up until recently, markets valuations are at all-time highs. Safe-haven assets-gold, the US dollar, and longer-dated government bonds-saw inflows as investors shifted away from riskier exposures.

Asian and European markets have felt the 'pinch' harder due to their higher energy dependence.

There is ongoing uncertainty as to how long the conflict might play out, what implications there are for global supply chains, and indeed potential inflationary pressures that ripple across global economies.

Central banks are having to make additional and complex judgment calls on their monetary policy settings. This in turn has ramifications for economic growth, in the form of a likely slowdown, likely-higher domestic interest rates, and relative currency valuations.

These added complexities might be perceived as a sudden extra 'tax' on everything, for instance, increased fuel and freight costs.

It could also be taken as a sign that the traditional correlations between the asset classes are breaking down in the short term and becoming less uniform, thus departing from long-evident historical patterns.

Diversification's critical role

Against this backdrop, diversification isn't just textbook advice-it's an investors' primary defence.

Spreading investment exposures across asset classes, regions, and industry sectors helps to lessen the impacts of sudden (adverse) volatility when one investment driver, such as energy, becomes a 'flashpoint'.

For example, a portfolio invested heavily in US tech (which is increasingly reliant on energy to power AI) or oil-dependent emerging markets, might suffer disproportionately; whereas an investment strategy balanced across commodities, quality government bonds, and other non-correlated alternatives may well be less sensitive to exogenous shocks like war and supply-chain bottlenecks.

Portfolio rebalancing at regular intervals can help prevents drifts in asset allocation exposures, and low-cost ETFs help make this process of adjustment easier than ever.

Yet, chasing 'hot' war stocks after the fact rarely pays off-markets have already priced in future expectations regarding valuations very quickly. However, the timeless truth remains: While diversification doesn't eliminate portfolio losses, it does help keep them insulated from large drawdowns overall.

Making life-stage adjustments

This brings us to an important evaluation when implementing an investment approach. Your stage in life should shape how you might respond to critical moments over the (long) investment horizon.

Younger investors (typically in their 20s-40s), and still in accumulation mode, tend to have higher exposures to equities and are more likely to see volatility as a buying opportunity. Long time horizons provide a greater means to benefit from the multi-decade investment cycle.

Mid-stage investors (40s-60s) need more balance and flexibility, and a lower allocation to growth-oriented and volatile asset classes, compared with a younger cohort

For pre-retirees and retirees (60s and over), asset preservation is usually the main priority. They tend to place an emphasis on cash buffers (highly liquid assets), high-quality bonds, and stable income sources to help avoid sequence-of-returns risk. Hence, a diversified, conservative mix of assets helps to meet this investor group's lifestyle needs.

While the commentary above are only generalised guidelines, all investors should consider their own needs, and preferably consult a licensed financial adviser.

Summary

The Iran conflict underscores a core reality: Geopolitics will always create noise, but sound investment principles endure.

Stay diversified, align with your life stage, and maintain a long-term investment horizon. And seeking quality investment advice from a licenced financial adviser could make all the difference.
