Oil Climbs to Four Week High as US Iran Conflict Fuels Hormuz Supply Fears

Oil prices climbed more than 3% on Tuesday, reaching their highest levels in four weeks, as renewed military tensions between the United States and Iran reignited concerns over global energy supplies moving through the Strait of Hormuz.

Oil prices climbed more than 3% on Tuesday, reaching their highest levels in four weeks, as renewed military tensions between the United States and Iran reignited concerns over global energy supplies moving through the Strait of Hormuz. Traders reacted to Washington’s decision to reimpose a naval blockade on Iran and escalating attacks that have increased fears of prolonged disruptions in one of the world’s most important oil transit routes.

Brent crude rose $2.74, or 3.29%, to $86.04 a barrel, while U.S. West Texas Intermediate gained $2.21, or 2.83%, to $80.35. The rally pushed Brent to its highest level since June 12 and WTI to its strongest level since June 16.

Why Oil Prices Are Rising

Market sentiment deteriorated after U.S. President Donald Trump reinstated a blockade of Iranian shipping and proposed a 20% security fee for vessels using the Strait of Hormuz. The move came despite a memorandum of understanding signed between Washington and Tehran on June 17 that was intended to end hostilities.

Analysts said investors are increasingly pricing in the possibility that the agreement may collapse if military confrontations continue.

ANZ analyst Soni Kumari said the market had expected tensions to ease following the agreement, but the rapid return of hostilities has forced traders to reassess geopolitical risks. While ANZ believes the worst escalation may be over, continued disruptions could keep Brent crude trading in the $85 to $90 range.

Hormuz Remains the Biggest Risk

The Strait of Hormuz remains the world’s most strategically important energy chokepoint, handling roughly one fifth of global oil and liquefied natural gas shipments before the conflict intensified.

Concerns grew further after two United Arab Emirates oil tankers were struck by Iranian cruise missiles in Omani waters, killing one Indian crew member and injuring eight others. Shipping data also showed tanker traffic through the strait fell to its lowest level in two months, raising fears that energy exports from the Gulf could face further disruptions.

Sanctions and Regional Tensions Add Pressure

Investment bank Citi warned that Iran could effectively suspend its understanding with Washington until after U.S. midterm elections, creating a scenario where oil prices remain elevated for a prolonged period.

Despite the renewed confrontation, Iranian Oil Minister Mohsen Paknejad said the country’s oil exports continue normally even after Washington cancelled a 60 day sanctions waiver last week.

Regional tensions also widened after Yemen’s Houthi movement launched missiles toward Saudi Arabia following accusations that Riyadh bombed an airport under Houthi control. Analysts said any expansion of attacks against Saudi oil infrastructure or Red Sea shipping would add fresh uncertainty to global crude supplies.

China Demand Provides Some Balance

Offsetting some supply concerns, China reported a sharp decline in crude imports. June imports fell 41.3% from a year earlier to their lowest level in nearly a decade as weak domestic demand, reduced refinery activity, and export restrictions on refined fuels weighed on purchases.

The weak Chinese demand outlook could partially limit further gains in crude prices, even as geopolitical risks continue to dominate market sentiment.

Why This Matters

The latest oil rally highlights how quickly geopolitical tensions in the Middle East can reshape global energy markets. With shipping through the Strait of Hormuz already slowing and regional attacks expanding, traders remain highly sensitive to any threat that could disrupt exports from Gulf producers. Higher oil prices also increase inflation risks worldwide, potentially complicating monetary policy for major central banks.

Future Outlook

Oil markets are likely to remain driven by geopolitical developments rather than fundamentals in the near term. Investors will closely monitor whether military activity around the Strait of Hormuz intensifies, whether tanker traffic recovers, and whether the United States and Iran make any renewed diplomatic efforts. While weaker Chinese demand could limit further gains, any additional attacks on energy infrastructure or shipping routes could quickly push Brent crude above the $90 per barrel mark.
