Oil Prices Surge as U.S.-Iran Conflict Escalates and Strait of Hormuz Risks Grow

Oil prices extended their strong rally in Asian trading on Tuesday after recording their biggest one-day gains in months, as escalating tensions between the United States and Iran heightened concerns over global crude supply and shipping through the Strait of Hormuz.

Brent crude futures for September delivery climbed 2.1% to $85.01 per barrel, while U.S. West Texas Intermediate (WTI) crude futures also rose 2.1% to $79.78 per barrel. Both benchmarks had surged nearly 10% in the previous session, reaching one-month highs as geopolitical risks intensified.

The latest gains came after U.S. President Donald Trump announced the reinstatement of a naval blockade on Iran following renewed military exchanges between Washington and Tehran. Trump also said the United States would impose a 20% charge on cargo passing through the Strait of Hormuz to help cover maritime security costs.

The U.S. military said enforcement of the blockade would begin on Tuesday, targeting vessels linked to Iran while allowing neutral commercial ships to continue using the strategic waterway.

Meanwhile, Iran launched drone attacks on U.S. assets in Kuwait and fired cruise missiles at a vessel in the Strait of Hormuz. The United Arab Emirates also reported attacks on two of its oil tankers in Omani waters, adding to fears that the conflict could spread across the region.

The Strait of Hormuz remains one of the world's most critical energy routes, carrying roughly 20% of global oil consumption. Any disruption to shipping through the corridor could significantly tighten global crude supplies and fuel further volatility in energy markets.

The renewed hostilities follow a weekend of missile and drone exchanges between U.S. and Iranian forces, effectively ending a fragile agreement reached last month to ease tensions around the vital shipping lane. Tehran has warned that continued U.S. military operations could lead to additional strikes on regional energy infrastructure.

The sharp rise in crude prices also weighed on broader financial markets, increasing inflation concerns and prompting investors to reassess the outlook for global economic growth and future central bank policy as higher energy costs threaten to keep price pressures elevated.
