US Iran War: Oil Prices Surge Past $100 as Crisis Enters Third Week

The US Iran war has sent shockwaves through global energy markets, with oil prices surging past $100 per barrel as the conflict enters its third week. The Strait of Hormuz, a critical chokepoint for approximately 20% of global oil supply, remains effectively closed, triggering what the International Energy Agency calls the largest oil supply disruption in global market history.

The situation represents a dramatic escalation in Middle East tensions, with Iranian forces continuing attacks on commercial vessels and the United States responding with military strikes on strategic infrastructure. According to the International Energy Agency, the disruption has already surpassed previous records, and market analysts warn of prolonged volatility ahead.

Strait of Hormuz Under Siege

The strategic waterway has become the epicenter of this escalating crisis. According to Reuters, oil settled up 9% as Iran vowed to keep the Strait of Hormuz closed, with Iranian forces continuing attacks on commercial vessels in the Persian Gulf. Iran's new Supreme Leader Mojtaba Khamenei has declared the Gulf will remain closed as a pressure tool against the United States and its allies.

The US military has responded with targeted strikes on Iran's Kharg Island, which handles about 90% of Iran's crude oil exports. As reported by CNBC, these strikes aimed to degrade Iran's ability to attack commercial vessels, but the situation remains highly volatile with no signs of de-escalation. The attacks on Kharg represent a significant escalation in the US Iran war, targeting the heart of Iran's oil export infrastructure.

IEA Launches Historic Reserve Release

In an unprecedented move, the International Energy Agency announced the release of over 400 million barrels from emergency reserves, marking the largest strategic petroleum release in history. The United States contributed an additional 172 million barrels from its Strategic Petroleum Reserve.

According to Goldman Sachs analysis, this represents the start of a new macro cycle, with oil prices surging 36-39% since the US Iran war began. The investment bank forecasts that by Q4 2026, Brent and WTI will average $71 and $67 respectively, reflecting a prolonged disruption modeled as a 21-day period of severely reduced flow through Hormuz.

The IEA's response highlights the severity of the situation. Countries around the world are coordinating to release strategic reserves in an attempt to stabilize prices and prevent economic chaos. However, many analysts remain skeptical that these measures will be sufficient to fully offset the supply gap caused by the ongoing conflict.

Human Cost and Regional Instability

The conflict has had devastating consequences beyond economic markets. According to NPR, the US Iran war has resulted in over 1,300 deaths in Iran, Lebanon, and Israel, with approximately 3.2 million Iranians displaced from their homes. Military casualties have been reported on both sides, including six US troops killed in a plane crash in Iraq.

The violence has spread beyond Iran's borders, with attacks expanding into Iraqi waters. Several commercial ships have been hit, including the Thai-flagged Mayuree Naree, heightening security concerns across the region. Insurance companies have dramatically increased war-risk premiums, adding further costs to global shipping.

Global Coalition Response

President Trump has urged allies to deploy warships as part of a coalition to escort tankers through the Strait of Hormuz. The US is also considering temporarily waiving the Jones Act to facilitate domestic energy and agricultural shipments amid the disruption.

The United States plans to form an international naval coalition to ensure safe passage for vessels through the contested waterway. However, as noted in recent reports from The New York Times, the US Navy is currently focused on degrading Iran's offensive capabilities rather than immediately escorting tankers.

Economic Fallout and Market Outlook

The US Iran war's impact extends far beyond the energy sector. Rising oil prices threaten to fuel inflation worldwide, potentially derailing economic recovery efforts in major economies. The Federal Reserve has responded by pausing interest rate adjustments in March 2026, but analysts doubt this will fully offset the supply constraints.

Market uncertainty persists regarding the duration of the Strait's closure and the speed of reserve releases. As the situation develops, investors and policymakers worldwide are closely monitoring the conflict's progression and its potential to further destabilize global energy markets.
