Global Oil Prices Rise Again After Trump Administration Conducts «Self-Defense» Strikes in Iran

Global oil prices surged again after the Trump administration launched new «self-defense» strikes inside Iran, shaking already fragile peace efforts and reigniting fears of a prolonged regional conflict that could further destabilize global energy markets. The renewed escalation came only days after President Donald Trump suggested a major diplomatic breakthrough was close regarding a possible accord involving Iran and broader Middle East normalization efforts linked to the Abraham Accords. Global energy markets had briefly reacted positively to signs of a possible de-escalation before fresh military action erased the short-lived optimism. Oil prices rapidly rebounded above the symbolic $100-per-barrel threshold after U.S. CENTCOM operations in southern Iran intensified fears that negotiations could once again collapse into broader warfare across the region.

Over Memorial Day weekend, international crude markets experienced dramatic swings as investors reacted to conflicting signals coming from Washington and Tehran. Brent crude reportedly fell more than 5% Monday to around $97.22 per barrel while West Texas Intermediate dropped near $90.68 after optimism spread that a diplomatic deal could eventually reopen safer shipping conditions through the Strait of Hormuz. Trump fueled those expectations after publicly stating that a peace agreement was close. «An agreement has been largely negotiated, subject to finalisation between the United States of America, the Islamic Republic of Iran, and the various other Countries, as listed. Final aspects and details of the deal are currently being discussed, and will be announced shortly,» Trump declared Saturday. Investors initially interpreted the statement as a signal that military escalation might finally slow following months of conflict that severely disrupted global oil supply chains.

Trump continued projecting cautious optimism Monday morning while simultaneously warning that negotiations could still collapse into renewed fighting if Iran refused final terms proposed by Washington and its regional allies. «Negotiations with the Islamic Republic of Iran are proceeding nicely! It will only be a Great Deal for all or, no Deal at all — Back to the Battlefront and shooting, but bigger and stronger than ever before — And nobody wants that!» Trump wrote as markets closely monitored every new development. The administration has reportedly attempted to combine negotiations with pressure campaigns tied to expanding diplomatic normalization between Israel and several Arab countries under a broader Abraham Accords framework. However, optimism surrounding the possible agreement rapidly weakened after Iranian officials publicly stated that no final accord was imminent while U.S. military operations resumed shortly afterward.

By Tuesday, crude markets had fully reversed course after fresh U.S. strikes in southern Iran reignited fears of deeper disruptions across the Middle East. Brent crude surged back above the psychological $100 mark while traders increasingly priced in the possibility of prolonged instability surrounding the Strait of Hormuz, one of the world's most strategically important oil transit corridors. Since hostilities first erupted in late February 2026, global energy markets have experienced historic volatility. Before the conflict, Brent crude traded relatively steadily between $70 and $73 per barrel. But the temporary closure of Hormuz triggered an immediate 51% surge in March that pushed oil above $103. Intensifying attacks and suspended Gulf transit later drove prices to an annual peak above $126 per barrel in late April before recent peace hopes briefly cooled markets again.

An hour away

The latest escalation came after Trump openly acknowledged the possibility of further military action against Iran despite ongoing diplomatic discussions. When questioned by reporters about whether the United States could strike Iran again, Trump responded: «I was an hour away […] We may have to give them another big hit. I am not sure yet. You will know very soon.» The comments immediately added to uncertainty already gripping global financial and commodity markets. Analysts warned that even limited strikes risk triggering retaliation from Iran or further disruptions to maritime shipping routes used to transport roughly one-fifth of the world's oil supply. Several shipping insurers and logistics firms have already raised rates dramatically in response to the growing security risks surrounding Gulf transit routes since the conflict began earlier this year.

International energy analysts now warn that oil markets could remain highly unstable for months if diplomatic negotiations fail to produce a lasting ceasefire agreement between the United States, Iran and regional actors. Governments across Europe and Asia have become increasingly concerned about the economic impact of sustained high energy prices as inflationary pressures continue affecting transportation, manufacturing and food supply chains worldwide. While Trump continues insisting that diplomacy remains possible, investors appear increasingly skeptical that peace negotiations can survive alongside continued military operations. The latest rebound in crude prices erased what traders had briefly described as a temporary «peace dividend» during the weekend decline, reinforcing fears that the conflict could once again spiral into a broader regional energy crisis with global economic consequences far beyond the Middle East.
