Oil prices surged and global stock markets faced pressure on Monday as escalating tensions in the Middle East following US-Israeli strikes on Iran raised fears of significant economic disruption. Brent crude jumped as much as 13% in early trading, reaching $82 per barrel, driven by concerns over potential supply disruptions as the Strait of Hormuz, a critical global trade route, faced increasing restrictions.

Why it matters

The Strait of Hormuz is a crucial global trade route, through which approximately 20% of the world's oil supply and seaborne gas tankers pass daily. Any disruption to traffic through the strait could have significant economic implications, particularly for the global oil market.

The details

Within hours of the US-Israeli strikes, Iranian Revolutionary Guards reportedly warned tankers in the strait that no ship would be allowed to pass. Reports indicated attacks on two ships in the strait, and marine tracking sites showed a buildup of tankers on either side, potentially due to safety concerns or difficulties securing insurance for passage. The International Maritime Organization urged ships to avoid the strait, and the global shipping company Maersk announced it was halting passage through the strait and the Suez Canal, citing 'safety' reasons.

What they’re saying

“I urge all shipping companies to exercise maximum caution. Where possible, vessels should avoid transiting the affected region until conditions improve.”

— Arsenio Dominguez, Secretary-General, International Maritime Organization (world-today-news.com)

“The most immediate and tangible development affecting oil markets is the effective halt of traffic through the strait of Hormuz, preventing 15m barrels per day of crude oil from reaching markets. Unless de-escalation signals emerge swiftly, we expect a significant upward repricing of oil.”

— Jorge León, Head of Geopolitical Analysis, Rystad Energy (world-today-news.com)

What’s next

The International Maritime Organization and global shipping companies will continue to monitor the situation in the Strait of Hormuz and provide guidance to vessels on the safety of transiting the area.
