• The overall impact on oil markets from the attack on Israel by Palestinian militants Hamas will likely be limited, provided the conflict does not escalate further, energy experts said.
• "We may see a knee-jerk surge in crude prices when markets open on Monday," Vandana Hari, CEO of Vanda Insights, told CNBC.

Crude oil prices could see a spike on Monday but the overall impact of the attack on Israel by Palestinian militants Hamas will likely be limited, energy experts told CNBC.

That's provided the conflict does not escalate further, they said.

"We may see a knee-jerk surge in crude prices when markets open on Monday," Vandana Hari, CEO of Vanda Insights, told CNBC via email.

"There will be some risk premium factored in as a default, until the market is satisfied that the event is not setting off a chain reaction and Mideast oil and gas supplies won't be affected," said Hari.

Militants from Hamas — designated by the U.S., European Union and the U.K.as a terrorist organization — infiltrated Israel by land, sea and air on Saturday, during a major Jewish holiday. The incursion came hours after the Islamist militants fired thousands of rockets into Israel from Gaza. 

Civilians including women, children and the elderly have been abducted, and others killed in their homes, Israeli Prime Minister Benjamin Netanyahu said.

Israel has begun the offensive phase, and will "continue with neither limitations nor respite until the objectives are achieved," Netanyahu said.

He vowed to "exact an immense price from the enemy, within the Gaza Strip as well." Late Saturday, Israel cut off the supply of electricity, fuel and goods to the narrow strip where 2.3 million Palestinians live.

At the time of publication, there were at least 250 Israelis killed and more than 1,860 injured, including 320 in serious condition, NBC News reported. The Palestinian Health Ministry recorded 256 deaths and 1,790 injuries in Gaza.

How much oil is involved?

Both Israel and Palestine are not major oil players, but the conflict sits in a wider key oil producing region, analysts told CNBC, warning that it has the potential to conflagrate further.

Hari noted that while the conflict does not directly impact oil production or supply, it is still "on the doorstep of an important oil-producing and exporting region."

Israel boasts two oil refineries with a combined capacity of almost 300,000 barrels per day. According to the U.S. Energy Information Administration (EIA), the country has "virtually no crude oil and condensate production." The Palestinian territories produce no oil, data from EIA shows.

Hari's sentiments were echoed by other market watchers.

"The impact on the oil price will be limited unless we see the 'war' between the two sides expand quickly to a regional war where the U.S. and Iran and other supporters of the parties get directly involved," Middle East managing director of energy consultancy Facts Global Energy, Iman Nasseri, told CNBC.

Similarly, French businessman and hedge fund manager Pierre Andurand said that since the Levant is not a large oil producing region, the war is unlikely to impact oil supply in the short term. 

"One should not expect a large oil price spike in the coming days. But it could eventually have an impact on supply and prices," he said in a post on X, the social media platform that was formerly Twitter.

Many people asked me if the Hamas attacks on Israel will have an impact on oil prices. As the Levant is not a large oil producing region, it is unlikely to impact oil supply in the short term. And therefore one should not expect a large oil price spike in the coming days. But it…

Andurand said global oil inventories are low, and production cuts by OPEC kingpin Saudi Arabia, as well as Russia, will lead to more inventory draws over the next few months.

"The market will eventually have to beg for more Saudi supply, which I believe, will not happen sub $110 Brent." 

Crude oil prices recently hit their highest level in more than a year before pulling back.

Still, Hari warned that the ongoing Israeli-Palestinian conflict "has the potential to widen into regional hostilities."

On Sunday, Lebanon's Hezbollah militant group confirmed it launched attacks on three sites in the Shebaa Farms — a strip of land that sits at the intersection of the Lebanese-Syrian border and the Golan Heights, which is occupied by Israel.

The Israeli Defense Force confirmed it has returned fire and "struck Hezbollah terrorist infrastructure."
