The recent escalation of tensions in the Middle East raises serious concerns regarding the global energy supply. Following missile attacks by U.S. and Israeli forces on Iran, an oil tanker docked off Oman caught fire, marking the beginning of a troubling trend of attacks on maritime vessels in the region. As these aggressive actions unfold, experts warn that the risks to global economies are mounting alarmingly.

The Strategic Importance of the Strait of Hormuz

Oman, located at the southern end of the Strait of Hormuz, serves as a critical maritime corridor that connects oil-rich nations in the Persian Gulf to the broader global market. Under normal circumstances, this narrow strait sees approximately 20 million barrels of oil traverse its waters each day, accounting for about 20% of the world’s liquid petroleum supply. However, amid rising regional instability, this vital shipping route could become a strategic bottleneck, leading to widespread economic repercussions.

The renewed conflict involving Iran has raised fresh alarms about the security of this maritime passage. As tensions escalate, analysts warn that even slight disruptions to petroleum shipments could send shockwaves throughout the global marketplace. The weekend’s missile attacks have compelled experts to predict that sustained fluctuations in oil supply could lead to a significant recession, an idea underscored by Bob McNally, founder of consultancy Rapidan Energy, who stated that a long-term closure of the Strait of Hormuz would almost certainly precipitate a global economic downturn.

Consequences for Global Energy Supply

It’s not only oil that stands at risk; the Strait of Hormuz also handles around 20% of the world’s liquefied natural gas (LNG) trade. In 2024 alone, Saudi Arabia was reported to have shipped about 5.5 million barrels of oil daily through the strait. While alternative routes exist, including pipelines through the Arabian Peninsula, their limited capacity is unlikely to compensate for any substantial loss of oil flows in the event of a prolonged strait closure. As such, the global energy market remains exceptionally vulnerable to persistent disruptions.

While the Iranian military has not yet made moves to enforce a closure, threats have prompted a considerable decline in maritime traffic through the strait. Reports indicate a staggering 70% drop in ship movement on the last observed day compared to previous figures, as alerts regarding the safety of this passage circulate. This dramatic decrease raises eyebrows among energy analysts and underscores the escalating risks associated with navigating these perilous waters.

Global Economic Fallout

Should the shipment of oil and gas come to a standstill, the global economy would likely experience severe ramifications. A simulation by the Oxford Institute for Energy Studies highlighted the potential impact of a year-long closure, predicting that 15% of the global LNG supply could vanish, with Europe and Asian countries like India and Japan being the hardest hit. The recent uptick in oil prices, including Brent crude soaring to $86 per barrel, reflects the anxiety gripping energy markets as uncertainty looms over the Strait of Hormuz.

While some banks and analysts assert that the likelihood of an oil price spike to $120 is relatively low, persistent tensions could change the calculus. The Iranian regime faces significant challenges in executing a full closure of the strait, including overwhelming U.S. naval presence. Despite previous threats to disrupt shipping, Iran has never fully acted on such intentions. However, the fear of economic instability may prompt them to reconsider their strategies.

Experts from Wood Mackenzie note that the most significant analogous event in history was the oil crisis of the 1970s, which led to economic downturns worldwide. Nowadays, the global economy exhibits less dependence on oil, indicating that oil prices would need to soar to around $200 a barrel to trigger similar upheaval. Still, the potential consequences of a sustained conflict affecting the Strait of Hormuz pose considerable risks not just for nations in the region but for international stability as a whole.
