Oil rises in choppy trade; US, Iran rhetoric heats up

Market Reactions and Geopolitical Tensions

Oil Price Movements

HOUSTON, April 6 (Reuters) - Oil prices climbed in choppy trade on Monday, as the U.S. and Iran ratcheted up their rhetoric even as the two countries are engaging in indirect talks that could lead to the de-escalation of hostilities.

Brent crude futures settled at $109.77 a barrel, up 74 cents, or 0.68%. U.S. West Texas Intermediate crude futures settled at $112.40, up 87 cents or 0.78%.

Impact of Strait of Hormuz Closure

For prices to decline to less exorbitant levels, any cessation of attacks would need to come with an agreement to open the crucial Strait of Hormuz, the shipping artery used by one-fifth of the world's oil and gas supply. Major oil consumers, particularly in Asia, are conserving barrels or cutting consumption in response to the closure of the strait. 

Diplomatic Efforts and Rhetoric

The U.S. and Iran received a framework from Pakistan to end hostilities, but Iran rejected the idea of immediately reopening the strait after President Donald Trump threatened to rain "hell" on the nation if it did not make a deal by the end of Tuesday. 

Current Status of the Strait of Hormuz

The strait, which carries oil and petroleum products from Iraq, Saudi Arabia, Qatar, Kuwait and the United Arab Emirates, remains largely closed due to Iranian attacks on shipping after the U.S.-Israel attacks began on February 28.

Some vessels, however, including an Omani-operated tanker, a French-owned container ship and a Japanese-owned gas carrier, have passed through the strait since Thursday, shipping data showed, reflecting Iran's policy to allow passage for vessels from countries it deems friendly.

Market Analyst Perspectives

"The market is trying to realise what to expect going forward. The most important headline this weekend has been that some ships passed through the strait," said SEB Research analyst Ole Hvalbye.

Hvalbye also highlighted that Europe continued to lose physical barrels and products to Asia due to the market tightening. 

Iran said it had formulated its positions and demands in response to recent ceasefire proposals conveyed via intermediaries.

"It's a very fluid situation with peace plans being put out there," said John Kilduff, a partner with Again Capital. "The rhetoric out of Iran seems to reject a ceasefire proposal, but they are allowing more ships through the Strait of Hormuz."

Monday's price moves followed an 11% surge for WTI and an 8% rise for Brent during the previous trading session on Thursday, the biggest absolute price increase since 2020. 

Seeking Alternative Sources

SEEKING ALTERNATIVE SOURCES 

Refiners' Response to Supply Disruptions

The Middle East supply disruptions have led to refiners seeking alternative sources for crude, particularly for physical cargoes in the U.S. and Britain's North Sea. Spot premiums for U.S. WTI crude have jumped to all-time highs on competition between Asian and European refiners.

Indian refiners have also postponed maintenance shutdowns of their units to meet local fuel demand.

OPEC+ and Saudi Arabia's Role

On Sunday, OPEC+, consisting of some members of the Organization of the Petroleum Exporting Countries and allies such as Russia, agreed to a modest rise of 206,000 barrels per day for May. 

"OPEC movements look to be challenged based on export availability," said Rystad analyst Janiv Shah.

Saudi Arabia also set the official selling price of May Arab Light crude oil to Asia at a record premium of $19.50 a barrel above the Oman/Dubai average, an increase of $17 from the previous month, Aramco said.

Russian Oil Supply and Export Updates

Russian supply has been disrupted recently by Ukrainian drone attacks on its Baltic Sea export terminals. Media reports on Sunday said its Ust-Luga terminal resumed loadings on Saturday after days of disruptions.

Exports from the Black Sea port of Tuapse are set to rise to 794,000 metric tons in April, up 8.7% on a daily basis from 755,000 metric tons planned for March, according to two traders and Reuters calculations.

Key Takeaways

  • The escalation in the U.S.–Israeli war against Iran, including threats to bomb power plants and bridges unless the Strait of Hormuz reopens, has heightened oil supply risk.
  • Global markets remain on edge, with the Strait of Hormuz still largely closed, choking off about 20% of daily oil and LNG flows.
  • Analysts warn that sustained disruptions could push prices even higher—forecasts now see Brent in the $105–$118 range or potentially surging to $130–$160 if escalation continues.
