Overview
On 14 July 2026, Reuters reported that oil markets extended a sharp rally in Asian trade after the United States reinstated a naval blockade on Iran. President Donald Trump announced the blockade and a 20 % charge on cargo transiting the Strait of Hormuz, citing security‑cost recovery.
Enforcement Details
The U.S. military stated that enforcement would begin on Tuesday, targeting vessel traffic linked to Iran while permitting neutral commercial shipping to continue through the waterway.
Iranian Retaliation
Iran launched drone attacks on U.S. assets in Kuwait and struck a vessel in the Strait of Hormuz with cruise missiles. The United Arab Emirates also reported that two of its tankers were attacked in Omani waters.
Price Reaction
At 20:56 ET (00:53 GMT), Brent Oil Futures for September expiry rose 2.1 % to $85.01 per barrel, and West Texas Intermediate (WTI) futures increased 2.1 % to $79.78 per barrel. Both benchmarks had surged nearly 10 % in the previous session, reaching one‑month highs and posting their biggest one‑day percentage gains in months on Monday.
Market Impact
The price jump weighed on global equities and heightened inflation concerns, prompting investors to reassess the potential impact of higher energy costs on global growth and central‑bank policy. Approximately 20 % of global oil consumption flows through the Gulf, and further military escalation could disrupt these supplies.
Contextual Note
The renewed hostilities follow a weekend of missile and drone exchanges that ended a fragile understanding reached the previous month to reduce tensions around the Strait of Hormuz.
