Oil Prices Reach New Highs Amid US-Iran Conflict

LONDON, April 30 (Reuters) - Global oil prices jumped to a four-year high of more than $122 a barrel on Thursday, on concerns that the U.S.-Iran war could worsen and lead to a protracted Middle East oil supply disruption that could hurt global economic growth.

The market moved higher after Axios, citing unidentified sources, reported late on Wednesday that U.S. President Donald Trump is slated to receive a briefing on Thursday on plans for a series of military strikes on Iran in hopes it will return to negotiations on its nuclear programme.

Brent and WTI Futures Performance

Global oil benchmark Brent crude futures rose $3.73, or 3.2%, to $121.76 a barrel as of 0820 GMT, after touching an intraday high of $126.41, the loftiest since March 9, 2022. The prompt contract for June delivery expires on Thursday. The more active July contract was at $111.89, up $1.45 or 1.3%.

The price of Brent crude has doubled since the U.S.-Israeli attack on Iran began on February 28 and the U.S. benchmark West Texas Intermediate crude is up around 90% due to the effective closure of the Strait of Hormuz, through which about a fifth of the world's oil and liquefied natural gas transits.

The oil price gains risk a renewed spike global inflation and higher pump prices in the U.S. ahead of mid-term elections later this year.

Market Sentiment and Analyst Commentary

"Oil prices need little encouragement to tempt them higher at present," said John Evans of oil broker PVM.

"For those who do not think Brent prices have the potential to reach $150 a barrel, you ought to look away now."

   WTI crude futures posed smaller gains,  rising $1.49, or 1.4%, to $108.37. The contract reached $110.93 earlier, the highest since April 7.

Both benchmarks are on track for their fourth month of gains, reflecting fears that the Iran conflict could choke global oil supplies for months to come.

Geopolitical Developments and Supply Disruptions

Trump called a ceasefire in the war earlier this month, but also imposed its own blockade on Iranian ports.

Talks to resolve the conflict, which has killed thousands and caused what the International Energy Agency says is the world's biggest oil disruption ever, have deadlocked, with the U.S. insisting on discussing Iran's alleged nuclear weapons programme and Iran demanding some control over the strait and reparations for damage from the war. 

"Prospects for any near-term resolution to the Iran conflict or a reopening of the Strait of Hormuz remain dim," IG market analyst Tony Sycamore said in a note.

TRUMP, OIL COMPANIES DISCUSS POSSIBLE EXTENDED BLOCKADE  

In a sign the conflict and resulting energy supply disruptions are set to continue for longer, Trump spoke on Wednesday with oil companies about how to mitigate the impact of a possible months-long U.S. blockade, a White House official said.

"In the near term, market participants remain focused on the dynamics of the U.S.-Iran conflict and the risk of a prolonged closure of the Strait of Hormuz," said OANDA senior market analyst Kelvin Wong.

This factor outweighs the long-term implications of the potential waning influence of OPEC+ following the exit of the United Arab Emirates from the group, he added.

OPEC+ Dynamics and UAE Exit

The UAE said on Tuesday it would quit the Organisation of Petroleum Exporting Countries after nearly 60 years as a member. The exit will complicate the efforts of OPEC+ - a wider group that includes OPEC plus Russia and other allies - to balance the market through adjustments to supply because the group would control less global production, OPEC+ sources said.

Even so, OPEC+ is likely to agree a small increase of around 188,000 barrels per day in its oil output quotas on Sunday, sources told Reuters on Wednesday, even though most producers cannot raise output due to the effective closure of the Strait of Hormuz.

Impact of UAE's Exit and Market Fundamentals

   The UAE's exit from OPEC and OPEC+  would allow it to raise production after exports restart, analysts say. However, this is unlikely to have much impact on market fundamentals for now given the Hormuz closure and production disruptions from the war.

Demand Destruction and Future Outlook

Analysts now say destruction in the demand for oil due to the high prices may be the most likely factor to alleviate the current tight supply situation.

ING analysts see about 1.6 million bpd of demand lost as consumers and end-users simply stop using oil products in some form because of high prices.

Though significant, "it’s clearly not enough to fill the supply gap we are currently facing," the analysts said in a note.
