As the geopolitical landscape shifts dramatically with the ongoing conflict in Iran, Asian markets have been shaken to their core, particularly those nations heavily dependent on imported energy. Following missile strikes by the United States and Israel on Iranian targets, oil prices have surged, raising alarm bells for investors and economists alike.
Oil Prices Spike Following Military Escalation
In recent days, the global oil benchmark has spiked by an astonishing 17%, surpassing US$85 per barrel. This surge is largely attributed to the heightened tensions in the Middle East, specifically the closure of the Strait of Hormuz—a critical waterway through which approximately 20% of the world’s oil and gas supplies transit. The ramifications of these developments have rippled through financial markets, provoking widespread concern.
While Australia’s stock market has fared somewhat better than its Asian counterparts, it still faced a notable decline of 3.8% in the past week. In stark contrast, South Korea experienced a catastrophic fall, with its stock market plunging by 13% in a single day, marking its most significant loss on record.
Investor Sentiment Wavers Amid Uncertainty
As the situation unfolds, investors have begun to question the potential for a prolonged conflict in the region. Historically, Donald Trump’s administration has exhibited a tendency to reverse course on military actions under pressure. However, with the current situation escalating, analysts warn that market optimism may be overly complacent in assuming a swift resolution.

Shane Oliver, Chief Economist at AMP, expressed his unease regarding this complacency, stating, “The mildness of the response has surprised me.” He highlights that the markets seem to be banking on a rapid de-escalation rather than preparing for a drawn-out conflict.
This uncertainty is reflected in the performance of the Australian dollar, which remains above 70 US cents—a sign of resilience amid the chaos. Ray Attrill, head of foreign exchange strategy at National Australia Bank, noted that Australia’s strength as a significant energy exporter is playing a role in this stability. He suggested that the prevailing assumption is that oil shipments through the Strait of Hormuz will soon resume, preventing significant long-term disruption.
The Stagflation Threat
The surge in oil prices poses a stagflationary risk, where rising fuel costs contribute to inflation while simultaneously hampering economic growth. This scenario places central bankers in a precarious position: they must choose between increasing interest rates to combat inflation or easing monetary policy to support economic activity.
Current forecasts from NAB economists indicate inflation may peak at around 4.75% in the year leading up to June, which is notably half a percentage point higher than previous predictions made before the Iran conflict escalated. Should oil prices continue to climb towards US$100 a barrel, inflation could potentially exceed 5%, marking a significant high not seen since late 2023.
Michele Bullock, Governor of the Reserve Bank of Australia, has signalled her awareness of the risks associated with rising petrol prices, stressing the importance of managing inflation expectations. She remarked, “This one might be a little bit harder… we already have elevated inflation, and I think there is a risk that inflation expectations might become a little bit unanchored.”
Investors Cautiously Monitor the Situation
Brett Solomon, a senior portfolio manager at QIC, noted that while investors have grown accustomed to geopolitical fluctuations, this situation may differ from past events that resolved within a week. The potential for a more protracted conflict introduces a level of uncertainty that could reshape market dynamics.

For now, many analysts maintain that the Reserve Bank of Australia may implement one more interest rate hike in May. However, the evolving situation surrounding oil prices will be crucial in determining whether this outlook holds.
Kerry Craig, a global market strategist at JP Morgan, echoed this sentiment, indicating that most investors still expect the conflict to remain short-lived. “The outlook for the global economy is fairly decent,” he stated, but cautioned that a shift in sentiment could materialise if the conflict persists.
Why it Matters
The ongoing conflict in Iran and the subsequent spike in oil prices have deep implications not only for the region but for the global economy at large. As countries grapple with the fallout from rising energy costs, the spectre of inflation looms large, compelling central banks to tread carefully. The interconnectedness of global markets means that investors must remain vigilant, as prolonged instability could lead to broader economic repercussions, affecting everything from consumer prices to employment levels.
