Iran war sparks oil surge and global market turmoil

Published: 02 March 2026. The English Chronicle Desk. The English Chronicle Online.

Oil prices surged sharply on Monday as the escalating Iran war rattled global financial markets. Investors reacted swiftly after coordinated strikes by the United States and Israel intensified tensions across the Middle East. The sudden spike in oil prices and the slump in major stock indices signalled deep anxiety about the global economy. Traders fear prolonged disruption to energy supplies as the Iran war shows little sign of easing.

Brent crude leapt by as much as 13 percent in early trading. Prices briefly touched 82 dollars a barrel, the highest level in fourteen months. Although gains later eased, Brent remained nearly eight percent higher at around 79 dollars. Analysts described the movement as a classic geopolitical shock amplified by fragile market confidence.

At the centre of these fears lies the strategically vital Strait of Hormuz. Roughly one fifth of global oil supplies and significant volumes of liquefied natural gas pass through the narrow waterway. Any disruption there carries immediate and severe consequences for energy markets worldwide. Following the weekend strikes, Tehran reportedly warned vessels against attempting transit.

Marine tracking services indicated congestion building rapidly on both sides of the strait. Several tankers appeared to delay passage amid concerns over safety and insurance coverage. While Iranian authorities have not formally declared a closure, market behaviour reflects genuine apprehension. Even partial disruption can tighten supply chains and inflate prices quickly.

Reports from the British maritime security body United Kingdom Maritime Trade Operations confirmed two separate attacks. One vessel was struck near Oman, while another incident occurred off the coast of the United Arab Emirates. Details remain limited, but the developments heightened shipping risks considerably.

The head of the International Maritime Organization, Arsenio Dominguez, urged caution among global shipping operators. He expressed concern about reports of injured seafarers during the attacks. Dominguez advised companies to avoid the affected waters where possible until security conditions improve. Such guidance underscores the gravity of the situation for international trade.

Shipping giant Maersk announced a temporary suspension of routes through both the Strait of Hormuz and the Suez Canal. The company cited safety risks for crews and cargo as its primary concern. This decision adds further strain to supply chains already challenged by geopolitical tensions.

Financial markets responded with immediate volatility across Europe and Asia. In London, the FTSE 100 dropped around one percent, closing near 10,798 points. Airline groups suffered notable losses as rising fuel costs threatened profitability. IAG fell close to ten percent, while easyJet declined by about seven percent.

Conversely, energy producers benefited from higher crude prices. Shares in Shell and BP climbed roughly six percent during trading. Investors also moved into defence stocks, anticipating sustained military activity. BAE Systems saw its share price jump around seven percent.

Elsewhere in Europe, markets mirrored London’s downward trajectory. Germany’s DAX fell by more than two percent. France’s CAC 40 and Italy’s FTSE MIB both recorded declines exceeding two percent. Spain’s Ibex 35 followed a similar pattern, reflecting broad regional unease.

Energy markets experienced even sharper reactions. European gas prices surged by up to 28 percent, marking the largest increase since August 2023. Electricity contracts in Germany and France also rose as fuel costs climbed. Higher wholesale prices threaten to renew inflationary pressures across the continent.

In Asia, Japan’s Nikkei 225 initially dropped nearly 2.4 percent before recovering slightly. Australia’s ASX 200 opened sharply lower but finished flat by day’s end. Mainland China’s Shenzhen Composite slipped modestly, indicating cautious regional sentiment.

Safe haven assets attracted renewed interest amid uncertainty. Gold prices climbed around 2.5 percent as investors sought stability. Traditionally, bullion performs well during periods of geopolitical turmoil and financial volatility. The current environment fits that pattern closely.

Military operations by the United States and Israel appear set to continue. Former US president Donald Trump suggested the conflict could extend for several more weeks. He indicated that operations would persist until strategic objectives were achieved. Such remarks have reinforced expectations of prolonged instability.

Iran remains a significant oil producer within the Opec+ alliance. It accounts for approximately 4.5 percent of global crude supply. Any interruption to its exports compounds broader concerns over shipping constraints. Even additional output agreed by Opec+ may struggle to reach markets if transport routes remain threatened.

Energy consultancy Wood Mackenzie described the crisis as a dual supply shock. Analysts warned that not only are current exports halted, but spare production capacity is effectively inaccessible. Without safe transit through the Strait of Hormuz, balancing the global oil market becomes challenging.

Some analysts now predict prices could exceed 100 dollars per barrel. Such levels would intensify inflation and strain household budgets worldwide. For the United Kingdom, higher fuel costs would directly impact transport and manufacturing sectors. Consumer confidence, already fragile, may weaken further under sustained pressure.

Central banks are likely monitoring developments closely. Rising energy prices complicate efforts to stabilise inflation after recent tightening cycles. Policymakers face a delicate balance between supporting growth and controlling price rises. Prolonged volatility may force difficult decisions in coming months.

Businesses dependent on stable supply chains also confront fresh uncertainty. Shipping delays increase costs and disrupt delivery schedules. Insurance premiums for voyages through contested waters are rising sharply. Smaller firms may struggle to absorb these additional burdens.

Despite heightened tensions, diplomatic channels remain active behind the scenes. International mediators are reportedly exploring avenues to reduce escalation. However, public rhetoric from all sides suggests compromise remains distant. Markets therefore continue to price in significant risk.

The human dimension of the Iran war should not be overlooked. Civilians across the region face insecurity and economic hardship. Seafarers navigating dangerous waters bear immediate physical risks. Global consumers, meanwhile, feel the consequences through higher living costs.

Financial strategists advise caution rather than panic. While markets often overreact initially, sustained conflict can alter fundamentals. Diversification and prudent risk management become essential during such periods. Investors are adjusting portfolios accordingly.

As the week unfolds, traders will watch shipping movements and official statements closely. Confirmation of any formal blockade would likely trigger further volatility. Conversely, signs of de-escalation could stabilise sentiment swiftly. For now, uncertainty dominates the outlook.

The Iran war has once again demonstrated the interconnected nature of global markets. A regional military escalation can ripple rapidly across continents. From London to Tokyo, investors are recalibrating expectations in real time. Whether stability returns soon depends largely on developments in the Gulf.
