Renewed US-Iran Strikes Send Oil Prices Higher as Global Markets React

WASHINGTON/DUBAI — Renewed military strikes between the United States and Iran have intensified tensions in the Middle East, with the escalation already reverberating through global energy and financial markets.

The United States launched a new series of airstrikes against targets in Iran on Tuesday, while Iran responded with attacks of its own, according to Reuters and The Associated Press. The latest exchanges have raised concerns about a wider regional conflict and the security of one of the world’s most important energy corridors.

The escalation has also pushed oil prices sharply higher.

Brent crude rose about 4.6 per cent to approximately $94.65 a barrel, while US West Texas Intermediate crude gained about 5.2 per cent to roughly $90.22, according to Reuters. The increases reflected renewed concern that military activity could disrupt energy supplies and shipping through the Strait of Hormuz.

The Strait of Hormuz is a critical passage for international energy shipments, making any sustained disruption there a potential concern for governments and markets far beyond the Middle East.

Markets respond

Financial markets also came under pressure as investors assessed the economic consequences of the renewed conflict.

Reuters reported that government bond yields rose across major markets, while stocks declined. The yield on the 10-year US Treasury note reached 4.792 per cent, its highest level since January 2025.

Higher energy prices can feed into transportation, manufacturing and household costs, adding to inflationary pressure at a time when central banks are closely monitoring price growth.

The renewed conflict has therefore introduced another source of uncertainty for policymakers, particularly if higher oil prices persist.

Civilian casualties reported

The military exchanges have also resulted in civilian deaths.

The Associated Press reported that a US strike hit an area in southern Iran where a wedding was taking place, with deaths and injuries reported. The Guardian reported that four people, including a child, were killed and more than 50 injured in the incident.

The competing military actions have raised fears that the conflict could expand beyond the immediate targets and draw additional countries or armed groups into the confrontation.

US President Donald Trump has warned Iran against further retaliation, while Iranian authorities have indicated that they intend to respond to the US attacks.

A broader economic risk

For countries dependent on imported fuel, a sustained rise in crude prices could have consequences beyond financial markets.

Higher oil prices can increase the cost of electricity generation, transportation and imported goods, placing additional pressure on consumers and businesses. Developing economies with limited fiscal room can be particularly vulnerable to prolonged energy shocks.

The Caribbean, which imports much of its fuel, is among the regions that could face indirect economic effects if higher global energy prices persist.

For now, the immediate focus remains on whether the latest military exchanges develop into a broader confrontation and whether shipping through the Strait of Hormuz remains secure.

The next stage of the conflict could have consequences not only for the Middle East but for energy markets, inflation and economic policy around the world.
