Strait of Hormuz Tensions: Oil Markets at Risk Amid US-Israel Attacks on Iran

Tensions are escalating in the Middle East as the Strait of Hormuz, a vital maritime channel for the global oil and gas supply, becomes the center of a conflict involving the US, Israel, and Iran. Amid military strikes by the US and Israel against Iran, Tehran has imposed a full blockade on the Strait of Hormuz, effectively halting all navigation through the vital waterway. This has led to a sharp increase in oil prices and widespread concern over potential global economic disruption.

The Importance of the Strait of Hormuz

The Strait of Hormuz, a narrow waterway between Iran and Oman, is of crucial strategic importance. Approximately 20 to 30 percent of the world's oil and gas supplies are shipped through this strait. Currently, around 150 tankers have dropped anchor in open Gulf waters on either side of the Strait following the escalation of conflict in the region.

The Escalation of Conflict

US-Israeli military strikes against Iran under Operation Epic Fury have triggered electronic warfare activity and multiple attacks on vessels along the Strait of Hormuz. In response, Tehran has declared the American military and any of their contingents in the region as legitimate targets. The escalation of conflict comes amid strikes on Iranian nuclear sites and a fragile ceasefire. Meanwhile, US and Iranian representatives have been meeting in Geneva to discuss Tehran's nuclear program, though hopes for a breakthrough are slim.

The Impact on Oil Markets

The blockade and ongoing conflict have brought oil shipments via the Strait of Hormuz to a standstill. Major oil companies and trading houses have suspended crude oil and fuel shipments through the Strait due to the heightened security risks. This has resulted in a significant surge in global oil prices; Brent crude, the global benchmark, surged as much as 14 percent to more than US$82 per barrel, the highest since January 2025.

Global Reaction and Implications

The international reaction to the conflict has been mixed. The US Congress is split on the issue, with Republicans broadly supporting President Donald Trump's decision to launch strikes against Iran, while Democrats criticize the operation as an undeclared war. A senior Iranian official has warned that there are no red lines in defending our country and that everything American or Israeli has become a legitimate target for the Iranian armed forces.

The sudden escalation of conflict and the effective closure of the Strait of Hormuz has alarmed global markets and led to fears of significant economic disruption. However, the global economy today is less vulnerable than during the 1973 oil crisis, despite the closure of the Strait of Hormuz and the ongoing US-Israeli strikes in Iran.

Current Status

At the moment, the Strait of Hormuz remains closed and the conflict shows no signs of abating. While Iran has stated that it has no intention to block navigation through the Strait, an official from the European Union's naval mission Aspides reported that vessels have been receiving transmissions from Iran's Revolutionary Guards stating that no ship is allowed to pass the Strait of Hormuz. As the situation unfolds, the world watches with bated breath, hoping for a peaceful resolution to the escalating conflict in this critical region.
