Global oil prices have surged to over $100 (£75.11) per barrel as fears mount over the ongoing US-Israeli military actions against Iran, which threaten to disrupt crucial oil shipments through the Strait of Hormuz. The current geopolitical turmoil has sent shockwaves through stock markets, with significant declines seen across Asia as investors react to the potential for prolonged instability in the region.
Escalating Tensions Fuel Price Hikes
This past Sunday, Iranian officials appointed Mojtaba Khamenei as the successor to his father, Ali Khamenei, as Supreme Leader, maintaining a hardline stance just one week into the conflict. The situation intensified as the US and Israel launched a series of airstrikes targeting Iranian oil facilities, exacerbating concerns over energy supply disruptions that could have far-reaching implications for global markets.
As of Monday morning in Asia, Brent crude climbed nearly 18% to reach $109.25, while Nymex light sweet crude increased by over 20% to touch $109.37. The immediate repercussions were evident in stock exchanges across the Asia-Pacific region, with Japan’s Nikkei 225 index plummeting more than 5%, South Korea’s Kospi dipping over 6%, and Australia’s ASX 200 falling nearly 4%.
Strait of Hormuz: A Critical Passage Under Threat
Approximately 20% of the world’s oil supply typically transits through the Strait of Hormuz. However, since the onset of hostilities, traffic through this vital waterway has significantly dwindled. Prior to this escalation, the markets appeared relatively unfazed, with many analysts predicting a rise to the $100 mark. Yet, the latest developments have triggered an immediate and dramatic market reaction.

The oil prices experienced a rapid spike, jumping 10% almost instantaneously and marking another 10% increase within just 15 minutes of early trading. Such volatility underscores the precarious nature of energy supplies in the Gulf, where the ongoing conflict has led to widespread destruction of critical infrastructure.
Future Projections: Higher Prices Ahead?
Analysts are now contemplating the potential for record oil prices should the closure of the Strait of Hormuz persist through the end of March. Adnan Mazarei from the Peterson Institute for International Economics remarked that the surging prices were anticipated given the halt in production across several Gulf nations and the signals pointing toward a protracted conflict.
“People are realising that this won’t end quickly,” Mazarei noted, emphasising that the commitments and assurances from the US appear increasingly unrealistic in light of the current situation. The rise in oil prices may also have cascading effects, raising costs for essential products including jet fuel and key ingredients for fertilisers.
Impact on Global Markets and Consumers
The implications of these price hikes are already being felt globally, particularly in Asia where demand for US gas is rising as buyers pivot from European sources. The fallout has led to some tankers initially destined for Europe changing course mid-Atlantic to satisfy growing Asian demand.

US President Donald Trump addressed the spike in oil prices, deeming short-term increases a “small price to pay” for the elimination of Iran’s nuclear threat. His energy secretary clarified that it is Israel, rather than the US, that is primarily targeting Iran’s energy infrastructure amid concerns regarding rising domestic fuel prices resulting from the conflict.
Why it Matters
The current situation in the Middle East has far-reaching consequences that extend beyond immediate price fluctuations. As tensions escalate, the potential for significant disruptions in oil supply could lead to heightened inflation and increased living costs worldwide. This scenario underscores the delicate balance of global energy markets and the vulnerability of economies reliant on stable oil prices. Stakeholders must remain vigilant as the conflict unfolds, recognising that the repercussions could ripple through every corner of the global economy.
