Oil settles up 9% as Iran vows to keep Strait of Hormuz closed

Oil Prices Surge Amid Escalating Middle East Tensions

By Siddharth Cavale

NEW YORK, March 12 (Reuters) - Oil prices settled up about 9% on Thursday, at their highest in nearly four years, as Iran stepped up attacks on oil and transport facilities across the Middle East, and the country's supreme leader vowed to keep the vital Strait of Hormuz shut.

Brent futures settled at $100.46 a barrel, up $8.48, or 9.2%, after touching a session high of $101.60. U.S. West Texas Intermediate crude settled at $95.70, up $8.48 or 9.7%. Both contracts settled at their highest since August 2022.

Market Reactions and Expert Insights

"The market is seriously unbalanced and that will continue until the Strait is reopened and upstream and downstream operations return to normal. It will not happen quickly,” said Jim Burkhard, vice president and global head of Crude Oil Research at S&P Global Energy. 

U.S. Energy Secretary Chris Wright told CNBC on Thursday that the U.S. Navy could not escort ships through the Strait of Hormuz now but it was "quite likely" that could happen by the end of the month.

Global oil prices are unlikely to hit $200 a barrel, Wright said, even as Iran continues to strike merchant ships.

Regional Impacts and Security Concerns

Two fuel tankers in Iraqi waters were struck by explosive-laden Iranian boats, Iraqi security officials said on Thursday. An Iraqi official told state media the country's oil ports have completely stopped operations. 

Oman shifted all vessels out of its main oil export terminal at Mina Al Fahal outside the Strait of Hormuz in a precautionary move, a Bloomberg News report said.

Recent Price Fluctuations

On Monday, Brent hit $119.50 a barrel, its highest since mid-2022, then dropped after U.S. President Donald Trump said the Iran war could be over soon.

To combat rising prices, the Trump administration is considering waiving the century-old Jones Act for a limited period to ensure energy and agricultural shipments can move freely between U.S. ports, White House press secretary Karoline Leavitt said on Thursday.

Supply Disruptions and Strategic Responses

SUPPLY HITS

The war is causing the biggest oil-supply disruption in the history of global markets, the International Energy Agency said on Thursday, a day after approving the release of a record volume of 400 million barrels of oil from strategic stockpiles.

IEA and Market Skepticism

A detailed breakdown has not been provided yet, so there is skepticism in the market that the full volume will actually be released, Energy Aspects analysts said, adding that the total barrels of mostly crude and some products inventories are only equivalent to 25 days of the current disruption to flows.

Production Cuts and Refinery Shutdowns

Middle East Gulf countries have cut total oil production by at least 10 million barrels per day - a volume equaling almost 10% of world demand, the IEA said in its latest monthly oil market report.

Middle East refineries have also shut in 2.35 million barrels per day of crude and condensate refining capacity, consultants IIR said.

Geopolitical Escalation and Global Responses

Regional Conflict and Shipping Disruptions

Lebanon's Hezbollah launched its biggest rocket salvo of the war on Wednesday, prompting Israeli strikes that shook Beirut. Hezbollah's attack also raised fears about Yemen's Houthis joining the war alongside Iran, which could further disrupt Red Sea shipping. 

Saudi Arabia has ramped up crude exports from its Red Sea port of Yanbu in recent days. 

China’s Measures to Secure Domestic Supply

China has ordered an immediate ban on refined fuel exports in March, a further step to preempt a potential domestic fuel shortage caused by the Middle East conflict, sources said on Thursday.

Key Takeaways

  • Explosive‑laden boats, reportedly from Iran, attacked two foreign fuel oil tankers in Iraqi territorial waters, igniting fires and escalating market concerns about Middle East supply stability (en.wikipedia.org).
  • In response, the International Energy Agency’s 32 members unanimously approved the largest coordinated release ever—400 million barrels from emergency reserves—to counter near‑total disruption of oil flows via the Strait of Hormuz (iea.org).
  • Despite the IEA’s intervention, oil prices remained under upward pressure due to the severity of the supply crunch—flows through the Strait of Hormuz fell to under 10% of pre‑conflict levels, intensifying fears of prolonged shortages (iea.org)
