Oil Prices Rise for Second Consecutive Week Amid US-Iran Conflict

Market Overview and Geopolitical Impact

SINGAPORE, Aug 21 (Reuters) - Oil prices were little changed on Friday, but were on track for a second weekly rise as the stalemated U.S.-Iran war continues to disrupt supply from the key Middle East producing region.

Recent Oil Price Movements

Brent crude futures rose 4 cents to $93.82 a barrel by 0142 GMT, after climbing 2.4% in the previous session. U.S. West Texas Intermediate crude futures slipped 6 cents to $86.78 a barrel, after climbing 2.3% in the prior session.

During the previous five days of gains, Brent gained more than 7% and WTI climbed more than 8%, reaching their highest since July 24.

Supply Concerns and Producer Reactions

Prices have climbed on concerns the inconclusive state of the U.S.-Israeli war on Iran will mean the continued curtailment of supply from major oil producers such as Saudi Arabia, Iraq, the UAE and Kuwait.

The earlier peace deal between them expired this week with no effort by either side to restart talks and U.S. President Donald Trump threatened economic retaliation against nations supporting Iran.

Analyst Perspectives

"Both sides are dug in but lacking the luxury of time to play the waiting game, against a backdrop of crude prices grinding unerringly higher," IG analyst Tony Sycamore said on Friday.

Escalating Tensions and Global Responses

On Wednesday evening, Trump threatened "economic warfare and isolation on an unprecedented scale" against Tehran, warning of consequences for any country that provided "any type of lifeline to Iran".

This week, the United Arab Emirates suspended all financial and economic transactions with Iran until further notice, highlighting the fraught ties between the major Gulf Arab oil producer and Tehran.

Impact on Oil Flows and Shipping

Thousands of people have been killed in the Iran war, which began on February 28 when the U.S. and Israel launched military strikes on Iran. Since then, Tehran's blockade of the Strait of Hormuz and Iranian attacks on energy facilities across the Middle East have disrupted global oil and gas flows.

Shipping traffic through the Strait of Hormuz on Wednesday was unchanged from the day before with nine vessel transiting the waterway, far below pre-war levels. Prior to the Iran war, shipments equal to about one-fifth of global consumption moved through the waterway.

Key Takeaways

  • Brent crude and WTI are both heading for second consecutive weekly rises, with Brent gaining over 7% and WTI more than 8% in the past five days.
  • Ongoing U.S.–Iran hostilities continue to suppress oil flows from Gulf producers, and vessel traffic through the Strait of Hormuz remains far below pre‑war levels of one‑fifth of global oil shipments.
  • Market sentiment remains elevated amid stalled peace talks, economic pressure threats from Washington, and Gulf states halting transactions with Iran, sustaining a substantial geopolitical risk premium.
