Oil rises as U.S. threatens Iran with economic isolation

• U.S. Treasury Secretary Bessent warned of unprecedented measures for Iran's 'economic isolation' while Defense Secretary Hegseth confirmed U.S. forces could maintain an indefinite port blockade
• The UAE reported that Iran attacked two state-owned Abu Dhabi National Oil Company vessels transiting the Strait of Hormuz on Thursday evening
• Both oil benchmarks remain up approximately 4% for the week despite a 2% dip Thursday, as concerns persist about energy supply disruptions through the critical strait

Summary: Oil Rises on U.S.-Iran Tensions Over Strait of Hormuz

Key Price Movements:

Oil prices climbed Friday morning amid escalating U.S.-Iran tensions. Brent crude rose 0.96% to $87.91 per barrel, while West Texas Intermediate (WTI) gained 1.08% to $82.13 by 2:55 a.m. ET. Both benchmarks are tracking weekly gains of approximately 4%, despite a 2% decline in Thursday's session.

Geopolitical Developments:

The rally follows aggressive U.S. rhetoric toward Iran, with Treasury Secretary Bessent warning of unprecedented "economic isolation" measures in a Newsmax interview. Defense Secretary Pete Hegseth indicated the U.S. naval blockade of Iranian ports could continue "indefinitely," heightening concerns about energy supply disruptions through the Strait of Hormuz—a critical global oil transit chokepoint.

Triggering Incident:

The United Arab Emirates reported Thursday evening that Iran attacked two vessels belonging to state-owned Abu Dhabi National Oil Company while transiting the strait, escalating regional tensions.

Market Context:

Thursday's price retreat came after reports suggesting oil exports through the strait remain higher than many independent estimates. However, expectations indicate global oil demand may fall further than previously forecast this year due to ongoing disruptions around the strait.

Implications:

The situation presents significant supply risk for energy markets, with the Strait of Hormuz handling a substantial portion of global oil flows. Continued blockade threats and regional attacks could sustain elevated oil prices and volatility, impacting inflation expectations and broader market sentiment. Investors should monitor diplomatic developments and actual supply disruptions closely.
