Global oil prices moved higher on Monday as fears about supply disruptions intensified following U.S. strikes on Iran’s key oil export facility at Kharg Island and renewed tensions around the Strait of Hormuz.

Brent crude rose about 1.8% in early trading, reaching roughly $104.98 per barrel, as markets reacted to another weekend of violence across the Middle East. Analysts say the escalating conflict is heightening concerns that energy supplies could be disrupted in one of the world’s most critical oil-producing regions.

President Donald Trump said Saturday that U.S. strikes had “totally demolished” much of the Kharg Island facility, Iran’s primary oil export hub. In remarks to NBC News, Trump also suggested further attacks on the site could follow.

At the same time, the president urged allied nations to help ensure the reopening and security of the Strait of Hormuz, a narrow waterway through which a significant share of the world’s oil shipments passes. The ongoing conflict and threats to shipping in the area have added volatility to global energy markets and raised fears of broader economic consequences.
