US considers indefinite Iran naval blockade as oil shortfall worsens

• Daily vessel traffic through the Strait of Hormuz has plummeted to 8 ships compared to 130-140 before the war began in February, with Iran demanding removal of sanctions and release of frozen assets before reopening the strait
• The IEA now projects global oil supply will drop by 4.3 million barrels per day (4%) in 2026, up from a 3.7 million bpd forecast just one month ago
• President Trump faces domestic pressure to end the unpopular war as high fuel prices drag down approval ratings ahead of November midterm elections, though he has resisted ground troop deployment

Summary: US Threatens Indefinite Iran Naval Blockade Amid Oil Supply Crisis

The United States is considering maintaining an indefinite naval blockade of Iran as regional tensions escalate and global oil supplies shrink, Defense Secretary Pete Hegseth announced on August 13, 2026. The blockade has severely damaged Iran's economy by cutting off its primary hard currency source.

Key Developments:

• Iran has attacked vessels attempting to transit the Strait of Hormuz, including two UAE state-owned Abu Dhabi National Oil Company ships on Thursday
• Daily vessel transits through the strait dropped to just 8 ships on Tuesday, down from a pre-war average of 130-140 vessels
• The strait previously handled one-fifth of global oil and liquefied natural gas flows before conflict began in February 2026

Economic Impact:

• The International Energy Agency forecasts global oil supply will fall 4.3 million barrels per day (4%) in 2026, up from a previous estimate of 3.7 million bpd
• High fuel prices are pressuring President Trump's approval ratings ahead of November midterm elections
• Economists warn of sharp global growth declines and potential recession if the conflict continues

Diplomatic Stalemate:

• A tentative June ceasefire deal has collapsed
• Iran demands removal of economic sanctions and release of frozen assets before reopening the strait
• The U.S. briefly lifted its blockade in mid-June for one month but has since reimposed it
• Washington previously stated it would lift the blockade once Iran and Oman agree to restore commercial shipping

Despite Trump's repeated threats of military escalation and claims of "total control" over the strait, he has avoided deploying ground troops while tightening economic sanctions that have failed to bring Tehran to negotiations.
