Crude Oil Prices Edge Higher as US Threatens Indefinite Naval Blockade of Iran | August 14, 2026

Oil prices edged higher on Friday, August 14, 2026, after the United States threatened to maintain a naval blockade of Iran indefinitely, reviving concerns over crude supply, as per news reports. The gains came after oil prices fell more than 2% in the previous session amid a weaker global demand outlook. 

Brent crude futures rose 9 cents, or 0.1%, to US$87.16 a barrel by 0130 GMT, while US West Texas Intermediate (WTI) crude futures gained 4 cents to US$81.29 a barrel.  

Despite the previous session's decline, Brent was on track for a weekly gain of around 4%, while WTI was also heading for a weekly rise of approximately 4%. 

US Threatens Indefinite Blockade of Iran 

As per news reports, the United States said on Thursday (August 13, 2026) that it could maintain a naval blockade of Iran indefinitely and increase economic pressure on Tehran as ceasefire talks have stalled. 

US Treasury Secretary Scott Bessent also indicated that Washington could announce additional economic measures against Iran in the coming week, adding to uncertainty surrounding the conflict and its potential impact on global energy supplies. 

Strait of Hormuz Remains a Key Supply Concern 

Iran has continued to restrict traffic through the Strait of Hormuz, a critical global energy route that carried around 20% of the world's oil before the conflict. The disruption has contributed to higher fuel prices and increased concerns about crude supply. 

Iran's recently appointed Basij paramilitary chief, Hossein Taeb, said the strait remains under the management and control of the Islamic Republic, according to semi-official Fars news. 

Demand Concerns Limit Oil Price Gains 

Supply risks have been partly offset by weaker demand expectations. The Organisation of the Petroleum Exporting Countries (OPEC) and the International Energy Agency lowered their outlooks for oil demand growth this week. 

US crude inventories also recorded their largest weekly increase in more than three and a half years, adding to concerns about demand and limiting the impact of geopolitical supply risks.

Vessels Attacked in Strait of Hormuz 

Two vessels operated by state-owned Abu Dhabi National Oil Company were attacked while transiting the Strait of Hormuz on Thursday evening, according to the UAE state news agency WAM. The UAE government condemned the incident as an Iranian attack. 

Conclusion 

Oil prices remain influenced by competing supply and demand pressures. The US blockade threat, disruptions around the Strait of Hormuz and attacks on vessels have heightened supply concerns, while weaker demand expectations and rising US crude inventories have weighed on prices.
