Escalation of Tensions in the Middle East: Resumption of Hostilities and Impact on the Oil Market
The escalation of tensions in the Middle East intensified on July 8, 2026, with the resumption of hostilities between the United States and Iran, following American strikes in response to Iranian attacks in the Strait of Hormuz. This situation led to the end of the ceasefire and caused a sharp rise in oil prices, with Brent Crude reaching 76 dollars, and instability in global financial markets. The United States also reinstated oil sanctions against Iran, reducing global supply.
On July 8, 2026, the Middle East experienced a significant intensification of tensions, marked by the resumption of hostilities between the United States and Iran, ending a previously effective ceasefire [Source 9, 10]. US President Donald Trump announced the end of this truce during the NATO summit, declaring that the ceasefire with Iran « is over » and that strikes had resumed on both sides [Source 9, 10].
This escalation follows massive American strikes against Iran, which occurred on July 7, 2026 [Source 8]. These actions were carried out in response to Iranian attacks on three commercial vessels, including a Qatari LNG tanker, in the Strait of Hormuz [Source 6, 8]. Alongside these strikes, Washington reinstated sanctions on Iranian oil and revoked Iran's oil exemption, which is expected to reduce global supply by 500,000 to 800,000 barrels per day [Source 6, 8]. Mark Rutte described the American attacks on Iran as « absolutely necessary » [Source 7].
In response to the American strikes, Iran threatened retaliation [Source 3]. The Iranian president, who was attending the arrival ceremony of the coffin of the late Supreme Leader Ali Khamenei in Najaf, Iraq, was forced to cut short his visit due to these events [Source 2]. Khamenei's coffin arrived in Najaf, one of the holy cities of Shiite Islam, for his burial [Source 2]. Iran projects its regional power [Source 1].
The economic impact of this escalation was immediate and notable. Oil prices surged, with Brent Crude increasing by 5.5% to reach 76 dollars [Source 8]. Oil climbed by more than 2% and bond yields also rose [Source 5]. The US dollar reached its highest level in a week, strengthening its demand as a safe haven [Source 4]. On stock markets, European markets recorded sharp declines, and inflationary concerns were rekindled [Source 10].
