Oil Prices Surge as US-Iran Conflict Escalates, Threatening Global Supply
Financial markets began the week on high alert as escalating conflict between the US and Iran raised fears of disruptions to oil supplies from the Middle East. Investors are shifting towards safer assets, whereas riskier market segments face sell-offs. The most significant impact is in the oil market, with prices rising sharply due to concerns about the stability of supplies through the strategically vital Strait of Hormuz.
Oil Prices Climb Amidst Geopolitical Risk
Brent crude jumped by 13% during early trading on Monday, March 2, 2026, approaching the $80 per barrel mark. TradingKey reports that WTI crude futures rose by more than 11% at the opening. The market is reacting to the potential for conflict expansion to limit exports from a region that provides a substantial portion of global supplies.
Commerzbank Chief Economist Jörg Krämer warned that sustained high oil prices could increase eurozone inflation by over one percentage point and reduce economic growth by several tenths of a percentage point.
Strait of Hormuz: A Critical Chokepoint
The Strait of Hormuz, a narrow waterway between Iran and Oman, is a crucial chokepoint for global oil shipments. It handles approximately 20% of global oil shipments and 21% of global LNG trade, essential for Middle Eastern energy exports. Iran has banned transit through the Strait following military actions, severely heightening geopolitical risks.
Iran has a history of using the Strait as a geopolitical bargaining chip, repeatedly threatening to close it during times of crisis. The Times of Israel notes that while Tehran has frequently issued warnings, it has never fully acted on them, though it briefly closed part of the strait during recent military drills.
Market Reactions and Sector Impacts
Regional markets have also been affected. The United Arab Emirates ordered stock exchanges in Dubai and Abu Dhabi to remain closed on Monday and Tuesday.
Gold, a traditional safe-haven asset, saw growth, with its price rising around two percent to $5,400 a troy ounce as capital moved away from riskier assets. The US dollar also strengthened, fulfilling its role as a safe-haven currency.
European stock markets experienced significant declines. The PX index of the Prague Stock Exchange lost roughly two percent, while the broader European STOXX Europe 600 index, the German DAX, and the French CAC 40 fell by approximately two to three percent.
Sector-Specific Performance
Energy companies are benefiting from rising oil prices and expectations of higher earnings, while defense stocks are also gaining due to anticipated increased defense spending. Rheinmetall shares added almost five percent.
Conversely, sectors sensitive to energy prices and the economic cycle are under pressure. Airlines and transport companies are weakened by rising fuel costs, with Lufthansa shares down around seven percent. European travel group TUI is also weakening, as investors anticipate a negative impact on tourism due to increased geopolitical uncertainty and potential travel disruptions.
Supply Disruption and Potential Consequences
The US-Iran conflict has effectively led to a de facto closure of the Strait of Hormuz through insurance withdrawal, putting roughly 20% of global oil supply at risk, along with critical volumes of jet fuel, LPG, and LNG serving Asian and European markets. Kpler reports that Russia stands to benefit as India and China pivot towards alternative suppliers.
Ole Hansen, chief commodity strategist at Saxo Bank, warned that Iran may attempt to draw Gulf Cooperation Council states into the conflict, potentially creating a pretext for attacks on regional oil infrastructure and significantly increasing the risk of supply disruptions.
Looking Ahead
The situation remains highly volatile and dependent on the evolving geopolitical landscape. Further escalation could lead to higher fuel prices and negative economic impacts globally. Market participants will closely monitor developments in the region and adjust their strategies accordingly.
