U.S. crude oil jumps as Biden comments on possible Israel retaliation on Iran

U.S. crude oil prices rose more than 4% on Thursday, on pace for a third consecutive session of gains on fears that Israel could strike Iran's oil industry in retaliation for Tehran's ballistic missile attack this week.

President Joe Biden was asked by reporters Thursday morning whether the U.S. would support an Israeli strike on Iranian oil facilities. Biden said: "We're discussing that. I think that would be a little – anyway." The president added that "there's nothing going to happen today."

Biden's comments were the catalyst that moved prices higher, said Daniel Ghali, senior commodity strategist at TD Securities. "Geopolitical risks in the Middle East are probably at their highest levels since the Gulf War," Ghali told CNBC.

The U.S. benchmark hit an intraday high of $73.95 per barrel, a gain of about 5.5%. West Texas Intermediate has gained more than 7% this week.

Here are Thursday's energy prices at 12:27 pm ET:

• West Texas Intermediate November contract: $73.33 per barrel, up $3.23, or 4.61%. Year to date, U.S. crude oil has gained more than 2%.
• Brent December contract: $77.11 per barrel, up $3.21, or 4.34%. Year to date, the global benchmark has is slightly ahead.
• RBOB Gasoline November contract:  $2.0769 per gallon, up 4.58%. Year to date, gasoline has pulled back about 1%.
• Natural Gas November contract: $2.961 per thousand cubic feet, up 2.6%. Year to date, gas has gained nearly 18%.

The risk of oil supply disruptions increases as fighting in the Middle East intensifies, but OPEC+ is sitting on a large amount of spare crude that could step into the breach, according to Claudio Galimberti, chief economist at Rystad Energy.

"This spare capacity is for now preventing runaway prices amid one of the deepest and most pervasive crises in the Middle East in the past four decades," Galimberti told clients in a Thursday note.

OPEC+ spare capacity would be sufficient to cover a disruption to Iran's exports if Israel strikes the Islamic Republic's oil infrastructure as retaliation for Tehran's ballistic missile attack, said Bjarne Schieldrop, chief commodities analyst at the Swedish bank SEB.

But traders would begin to worry about supply disruptions in the Strait of Hormuz, Schieldrop said. "That would add a significant risk premium to oil," he told CNBC's "Street Signs Europe."

As a consequence, oil prices could surge to $200 per barrel if Israel hits Iran's oil infrastructure, he said.
