Global financial markets are being driven by a geopolitical shock—an escalating conflict involving Iran that has disrupted oil flows and injected sustained volatility into energy prices—yet equity markets in Australia and Japan are showing signs of resilience rather than panic.

What is confirmed is that oil prices have surged to multi-year highs amid fears that the conflict could severely constrain supply, particularly through the Strait of Hormuz, a critical artery for global energy transport.

Prices briefly spiked above levels not seen in years before retreating, reflecting extreme volatility rather than stability.

The swings are being driven by alternating expectations of military escalation and partial de-escalation, alongside profit-taking by investors.

Against that backdrop, stock markets in Australia and Japan have recently edged higher or stabilized, even as the broader global picture remains fragile.

This apparent contradiction reflects a shift in investor behavior: markets are increasingly pricing in the possibility that the conflict, while severe, may not fully halt global energy flows, or that governments and supply chains can adapt quickly enough to avoid worst-case economic outcomes.

The mechanism behind the market gains is not optimism about the conflict itself but a recalibration of risk.

Earlier phases of the war triggered sharp sell-offs across Asia-Pacific equities, with Australian markets losing tens of billions in value in days and Japan’s benchmark index recording steep declines.

Those moves were driven by sudden spikes in oil prices, inflation fears, and expectations of slower global growth.

The recent rebound reflects a partial unwinding of those fears as oil prices pulled back from peak levels and investors reassessed immediate supply risks.

Energy price dynamics remain central.

Oil has nearly doubled since the conflict intensified, raising the cost of transport, manufacturing, and electricity generation worldwide.

For import-dependent economies like Japan, this represents a direct hit to corporate margins and household spending.

Australia faces a different mix of pressures, as a major energy exporter but also a country exposed to global inflation and financial market swings.

The key issue is that equity markets are attempting to look past immediate disruption and focus on medium-term earnings and policy responses.

Strong corporate results in some sectors, particularly technology and energy, have provided support.

At the same time, expectations that central banks may proceed cautiously on interest rates—despite inflation risks—have helped stabilize valuations.

However, the underlying risks have not diminished.

The conflict has already reduced shipping through one of the world’s most important oil corridors to a fraction of normal levels, tightening supply and increasing the likelihood of prolonged high energy costs.

This raises the prospect of stagflation, where economic growth slows while inflation remains elevated, a combination that historically undermines equity performance.

The divergence between rising markets and worsening geopolitical conditions highlights a critical feature of modern financial systems: prices are driven not just by current events but by expectations of how those events will evolve.

Investors are effectively betting that the conflict will not escalate to a level that causes sustained, systemic disruption to global trade.

The immediate consequence is a fragile equilibrium.

Markets in Australia and Japan are holding up, but that stability rests on assumptions about containment, supply adaptation, and policy support.

As long as oil flows remain partially intact and volatility does not translate into physical shortages, equities can continue to recover ground even in the shadow of an active geopolitical crisis.
