US eyes indefinite Iran naval blockade as oil supply shortfall deepens

• Vessel traffic through the Strait of Hormuz has plummeted to 8 ships on Tuesday from a pre-war average of 130-140, with Iran attacking UAE oil tankers and demanding removal of sanctions before reopening the strait
• Global oil supply is forecast to drop by 4.3 million barrels per day (4%) in 2026, up from a 3.7 million barrel projection just one month earlier
• President Trump faces domestic pressure to end the unpopular war as high fuel prices drag down his approval ratings ahead of November midterm elections, though economic sanctions have failed to bring Iran back to negotiations

US Eyes Indefinite Iran Naval Blockade as Oil Supply Shortfall Deepens

Key Developments:

U.S. Defense Secretary Pete Hegseth announced Thursday that the United States may maintain an indefinite naval blockade of Iran, intensifying economic pressure as ceasefire negotiations have collapsed. The blockade, which can be sustained through rotating naval deployments, aims to restrict Tehran's access to hard currency from oil exports.

Critical Infrastructure Impact:

The Strait of Hormuz, which previously handled one-fifth of global oil and liquefied natural gas flows, has seen vessel traffic plummet to just eight ships on Tuesday from pre-war levels of 130-140 vessels. Iran maintains the strait will remain blocked until the U.S. removes economic sanctions and releases frozen Iranian assets.

Market Implications:

The International Energy Agency (IEA) now forecasts global oil supply will decline by 4.3 million barrels per day (4%) this year, up from last month's projection of 3.7 million bpd. Despite this supply constraint, oil prices settled lower Thursday due to weaker demand signals and rising U.S. crude inventories. However, Iranian drone attacks on a Saudi Aramco refinery have renewed concerns about regional escalation.

Geopolitical Tensions:

The UAE condemned Iran for attacks on two state-owned Abu Dhabi National Oil Company vessels transiting the strait Thursday. President Trump faces mounting domestic pressure over high fuel prices ahead of November midterm elections, while repeatedly asserting U.S. "total control" over the waterway.

Economic Outlook:

Global economists warn of sharp growth deceleration and potential recession in some regions if the conflict persists, with impact severity increasing the longer hostilities continue.
