Oil prices surged more than $3 per barrel on Friday, reaching their highest closing levels in nearly six months as escalating attacks in Saudi Arabia, tanker security concerns and additional Middle East supply disruptions pushed geopolitical risk back to the center of the market.

MONTREAL (Oil Monster): Oil prices climbed sharply on Friday as traders returned their focus to the risk of further Middle East supply disruption following an escalation of attacks in Saudi Arabia and renewed concerns over shipping security around the Gulf.
Brent crude futures settled at $116.72 per barrel, up $3.55, or 3.14%, marking their highest close since April 29.
U.S. West Texas Intermediate crude settled $3.80 higher, or 3.8%, at $103.27 per barrel.
The rally marked a dramatic reversal from early Asian trading, when both benchmarks were slightly lower.
Friday Market Close
Brent: $116.72/barrel | +$3.55 | +3.14%
WTI: $103.27/barrel | +$3.80 | +3.8%
Brent weekly move: +6%
WTI weekly move: +2.3%
The latest oil rally was driven largely by renewed concern over energy infrastructure and shipping security in Saudi Arabia and surrounding Gulf markets.
Fighting between Saudi Arabia and Yemen's Iran-aligned Houthi movement has intensified, with attacks increasingly reaching airports, oil facilities and other strategic infrastructure.
LPL Financial strategist Adam Turnquist said fears of further supply disruption strengthened after a series of attacks across Saudi Arabia, including strikes involving energy infrastructure.
The developments have raised questions over whether the recent recovery in Middle East crude exports can be sustained if attacks continue to broaden.

The market is no longer reacting only to barrels that have already been lost.
Middle East exports have recovered significantly, but traders are increasingly pricing the risk that those flows could be disrupted again.
That explains why oil can rise even while current export volumes improve: the premium reflects uncertainty over whether today's supply can still be delivered tomorrow.
Saudi Aramco instructed employees at its headquarters in Dhahran to evacuate and work remotely on Thursday, according to people familiar with the decision.
The move came one day after an attack on King Fahd International Airport in nearby Dammam killed two people and injured eight others.
Dhahran is approximately 15 kilometres south of the airport and sits at the center of Saudi Arabia's eastern oil-producing region.
Aramco's headquarters had also suffered extensive damage from a Houthi strike earlier in October, according to Reuters sources.
The building hosts an operations center used to oversee oil fields, refineries, export terminals and pipeline systems.
The reason for Thursday's evacuation was not publicly confirmed, and the order should not be interpreted as evidence that Saudi oil production itself had been halted.
Saudi authorities said two people were killed Wednesday after air defenses intercepted a drone targeting a facility at Aramco's Shaybah oilfield.
Shaybah is located in southeastern Saudi Arabia near the border with the United Arab Emirates and is one of the kingdom's major producing areas.
The incident followed a series of attacks and attempted strikes on Saudi energy and transportation infrastructure.
Saudi Arabia has responded with attacks on Houthi missile-launch positions while continuing efforts to strengthen defenses around critical infrastructure.
Concern is also increasing around commercial vessels operating in the Gulf and nearby waterways.
October has been one of the most disruptive months for commercial shipping around the Strait of Hormuz and surrounding waters since the conflict intensified.
Shipping operators have faced repeated attacks, elevated war-risk insurance costs and continuing uncertainty over the safety of tanker routes.
Oil flows have nevertheless increased in recent weeks as producers rely on alternative routes, shuttle tankers and ship-to-ship transfers.
Why Shipping Risk Matters
Another potential supply concern emerged Friday when the United Arab Emirates reported an oil spill off the coast of Umm Al Quwain.
The UAE Ministry of Climate Change and Environment said the spill originated from a tanker.
Authorities had not publicly identified the vessel or disclosed the cause of the incident when the market closed.
The spill added to broader concerns about tanker operations in regional waters, although there was no immediate indication that it had disrupted major UAE oil exports.
Outside the Gulf, oil production in Libya also came under pressure.
The head of Libya's National Oil Corporation said a pipeline valve carrying crude from the Hamada and Tahara oilfields toward the Zawiya export system had been shut.
The closure reduced production at both fields.
No precise volume reduction was disclosed in the Reuters report.
The Libyan disruption is smaller than the potential risks facing Gulf exports, but it adds another source of uncertainty to a global market already operating with expensive freight and tight refined-product supply.
Diplomatic developments involving Russia and Ukraine continue to provide some downward pressure on the geopolitical oil premium.
Russia said it is prepared to resume U.S.-mediated negotiations with Ukraine next month.
Ukrainian President Volodymyr Zelenskiy said Friday that Ukrainian, Russian and U.S. negotiators had agreed to hold technical-level talks in Abu Dhabi during the first half of November.
Any reduction in hostilities could improve the outlook for Russian refining and petroleum-product exports, particularly diesel, which remains unusually tight globally.
However, fighting continues while negotiations are being prepared, limiting the immediate effect on physical supply.

The Russia-Ukraine talks are bearish for oil in theory, but Middle East risk is dominating the market today.
A peace agreement could eventually return more Russian fuel supply and reduce pressure on diesel markets.
But the potential impact is months away and remains uncertain.
By contrast, tanker attacks, Saudi infrastructure risk and Gulf shipping disruptions are affecting the market now.
The United States also took additional emergency supply action Friday.
The Department of Energy authorized an exchange of up to 400,000 barrels of crude from the Strategic Petroleum Reserve to address a temporary supply disruption affecting Phillips 66's Lake Charles refinery in Louisiana.
The crude will come from the West Hackberry SPR site for immediate delivery.
Under the exchange structure, Phillips 66 must return the borrowed crude plus additional premium barrels to the reserve.

Volume: Up to 400,000 barrels
Recipient: Phillips 66 Lake Charles refinery

Structure: Borrowed crude must be returned with premium barrels
Another supply development came from Russia.
The first Russian diesel cargo bound for the United States since Moscow and Washington reached a new export arrangement departed Russia's Baltic port of Primorsk on October 22.
The tanker is carrying approximately 40,000 metric tons of ultra-low-sulfur diesel and is expected to arrive in New York in early November.
The shipment is intended to form part of a broader effort to increase global diesel availability while prices remain elevated.
Its near-term impact on the oil market is limited by the relatively small volume, but it is another sign that governments are pursuing multiple channels to increase petroleum supply.
Additional oil production does not automatically mean cheaper delivered crude.
Tanker shortages and war-risk costs have pushed international crude transportation expenses sharply higher.
OilMonster reported this week that U.S.-to-Asia crude freight had approached $40 per barrel in some trades, while Goldman Sachs estimates average global crude freight costs above $20 per barrel.
That means refiners can still face high feedstock costs even when headline export volumes are recovering.
The early Friday market initially appeared headed toward a mixed weekly performance.
That changed after crude prices rallied strongly through the session.
Brent ultimately finished the week approximately 6% higher.
WTI gained about 2.3%, extending its overall recovery despite the earlier expectation that it could finish the week lower.
The move illustrates why early-session pricing should be treated cautiously during periods of extreme geopolitical volatility.
Next Week's Key Oil Signals
The Bottom Line
Middle East crude exports have recovered substantially from the severe disruptions seen earlier in the year.
But Friday's price action shows that traders remain unconvinced those flows are secure.
The market is increasingly focused on the resilience of the infrastructure behind the barrels: tankers, pipelines, airports, export terminals and the facilities coordinating Saudi production.
Oil supply has recovered faster than confidence in that supply, and that gap is now supporting a significant geopolitical premium in crude prices.
