Oil prices could be pushed into "uncharted waters" if the violence between Israel and Palestine intensifies, which could result in increased food prices worldwide, the World Bank warned Monday.

The World Bank’s Commodity Markets Outlook found that while the effects on oil prices should be limited if the conflict doesn’t widen, the outlook "would darken quickly if the conflict were to escalate."

Israel launched a complete siege and unprecedented strikes on Gaza after a surprise cross-border attack by the Palestinian resistance group Hamas on Oct. 7, raising fears of a wider Mideast conflict.

Israeli bombing has now killed more than 8,000 people in Gaza, mostly children, according to Palestinian officials.

Some 1,400 people are said to have been killed in Israel.

And the threat of escalation looms.

Israeli tanks and infantry pushed into Gaza over the weekend as Israeli Prime Minister Benjamin Netanyahu announced a "second stage" in the conflict. Hamas officials have called for more regional assistance from allies.

The World Bank report simulates three scenarios for the global oil supply in the event of a small, medium, or large disruption.

Effects should be limited if the conflict doesn’t widen in a "small disruption" scenario – as oil prices are expected to decline to an average of $81 a barrel next year, the World Bank estimates.

But during a "medium disruption" – equivalent to the disruptions experienced during the Iraq War – the global oil supply would decline by 3 million to 5 million barrels per day, driving oil prices up possibly by 35%.

In a "large disruption" scenario – comparable to the Arab oil embargo of 1973 – the global oil supply would shrink by 6 million to 8 million barrels per day and prices could go up by 56% to 75%, or $140 to $157 a barrel, according to the report.

Indermit Gill, the World Bank’s chief economist, said Russia’s invasion of Ukraine has already had disruptive effects on the global economy "that persists to this day."

"If the conflict were to escalate, the global economy would face a dual energy shock for the first time in decades – not just from the war in Ukraine but also from the Middle East," Gill said.

Ayhan Kose, the World Bank’s deputy chief economist, said higher oil prices will inevitably result in higher food prices.

"If a severe oil price shock materializes, it will push up food price inflation that has already been elevated in many developing countries" as a result of Russia’s Ukraine invasion, Kose said. "An escalation of the latest conflict would intensify food insecurity, not only within the region but also across the world."

Overall, oil prices have risen about 6% since the start of the conflict. And gold – a commodity that tends to rise in periods of conflict – has increased by roughly 8%, according to the World Bank.

Some analysts are skeptical that the U.S. would experience massive oil shortages since U.S. oil production is at an all-time high.

At a Bloomberg event on Thursday, Treasury Secretary Janet Yellen said the Biden administration was monitoring the economic consequences of Israel’s war against Hamas carefully.

"So far, we have not yet seen much that has global consequences," she said, but if the war spreads, "of course there could be more meaningful consequences."

International Energy Agency Executive Director Fatih Birol said between Russia’s invasion and the latest violence between Israel and Hamas in Gaza, "no one can convince me that oil and gas are safe and secure energy choices for countries or consumers."
